FSMA 204 Implementation Guide: Building a Traceability Program from Scratch

TL;DR: The Food Safety Modernization Act (FSMA) Section 204 compliance deadline is July 20, 2028. You must map Critical Tracking Events (CTEs) and Key Data Elements (KDEs) to a Traceability Lot Code (TLC) scheme, connect those records to your existing systems, and prove the full chain of custody to the Food and Drug Administration (FDA) within 24 hours of a request. Meeting the paperwork standard satisfies the regulatory floor. Pairing that compliance program with real-time, sensor-based condition monitoring is what stops physical product loss during transit, which is the operational outcome your program should target. A single spoilage event caught in transit on a high-value produce lane covers months of monitoring costs.

The hardest part of FSMA 204 compliance is not designing the Traceability Lot Codes. It is closing the data gaps that occur during carrier handoffs, where paper records disappear and temperature excursions go undetected until a load reaches the dock already spoiled. A passive temperature logger tells you that a shipment of fresh berries deviated three days ago. A sortable audit spreadsheet tells you who was holding those berries when it happened. Neither tool stops the product from degrading in transit.

This guide walks through all six implementation phases, from product scoping to pilot testing, with direct attention to the decisions that determine whether your program holds up under an FDA inspection or collapses under missing lot codes and unrecorded carrier handoffs.

What FSMA 204 Requires from Your Traceability Program

Understanding those obligations starts with three specifics: which products are covered, which data fields must be recorded, and which supply chain events trigger that requirement.

FSMA Section 204 requires you to maintain traceability records for every food listed on the FDA Food Traceability List (FTL) that your facility manufactures, processes, packs, or holds. The FDA extended the federal compliance deadline to July 20, 2028, and Congress made that extension legally binding through appropriations legislation passed in November 2025, but that extension does not signal a softer standard. Retail contract terms in produce and perishables increasingly require faster-than-24-hour traceability data turnaround, ahead of the FDA's own deadline.

Mapping Products for FSMA 204 Compliance

Start by auditing every product in your inventory against the FDA's Food Traceability List. FTL categories include leafy greens (romaine, spinach, arugula, kale, chard), fresh and fresh-cut herbs, cucumbers, fresh peppers, fresh tomatoes, fresh melons, tropical tree fruits, sprouts, fresh-cut fruits and vegetables, ready-to-eat refrigerated deli salads containing at least one FTL food, shell eggs, nut butters, soft and semi-soft cheeses, fresh and smoked finfish, crustaceans, and mollusks. This is not exhaustive. Audit your inventory against the full FDA Food Traceability List directly, as the agency updates scope and guidance. Whether a multi-ingredient product falls under the rule depends on the form of the FTL food present and how it is used. Route any borderline product to Quality Assurance (QA) for a documented inclusion decision, and confirm the determination with your regulatory counsel or directly with FDA guidance before excluding it from scope.

Essential KDEs for FSMA 204 Compliance

KDEs are the specific data fields the FDA requires you to record at each CTE. KDEs include the Traceability Lot Code, product description, quantity and unit of measure, dates and times, location identifiers, and reference document numbers. Link each KDE to a specific TLC so investigators can filter records instantly by lot, location, or trading partner.

Mapping CTEs to Your Operational Flows

A CTE is the supply chain event that triggers the requirement to capture KDEs. The seven CTEs under FSMA 204 are Harvesting, Cooling, Initial Packing, First Land-Based Receiving (seafood), Shipping, Receiving, and Transformation. Shipping and Receiving apply to essentially every business that moves FTL food between entities. Map each CTE to the physical moment in your operation: a trailer being loaded triggers the Shipping CTE, and a trailer being unloaded triggers the Receiving CTE. Those are the exact moments KDE capture must occur, not at end-of-day batch processing.

Traceability Lot Code (TLC) Scheme Requirements

The TLC is the single identifier connecting a product's origin to its final destination. Design your TLC to remain unchanged through every Shipping and Receiving CTE unless a Transformation event occurs. Allowing lot codes to change during transit is the most common implementation failure, and it breaks the chain of custody that FDA investigators expect to trace in a single query.

Phase 1: Define Your Traceability Program Boundaries

Before assigning lot codes or configuring systems, establish exactly which products, facilities, and trading partners fall within your program scope.

FSMA 204 Product Inclusion Criteria

Answer three questions for each product in sequence:

1. Does the finished product contain any FTL ingredient, even as a minor component?
2. Does the product move between trading partners (farms, processors, distributors, retailers)?
3. Does the facility hold and process FTL foods as part of its commercial operations?

If all three are yes, the product is covered. Mixed-ingredient products require a bill-of-materials review, and QA must document the inclusion decision with a dated rationale retrievable during an audit.

Define Your FSMA Traceability Flow

Map the physical path of each FTL product from its initial supplier, through warehouses and carrier handoffs, to the final receiver. Mark every point where custody changes hands, because carrier handoffs are where paper records are most likely to disappear and where temperature excursions are least likely to be recorded. A single device traveling with the cargo across all modes reduces the fragmented records that accumulate when different carriers contribute separate logs.

Defining Internal Roles for FSMA 204 Compliance

Assign internal program ownership clearly before the design phase:

• QA: Owns the compliance standard, validates data completeness, and approves the KDE schema.
• Warehouse operations: Executes data capture at CTEs, manages physical lot code labeling, and escalates discrepancies during receiving.
• Information Technology (IT): Configures system integrations, establishes API connections, and maintains data retention infrastructure.

Defining External Roles for FSMA 204 Compliance

External roles carry equal compliance weight. Draft a supplier compliance matrix that assigns responsibilities to each trading partner:

• Upstream suppliers: Must provide TLCs and corresponding KDEs with every inbound shipment, delivered digitally in advance shipping notices (ASNs).
• Carriers: Must preserve lot code integrity during transport and document handoffs at each custody transfer.
• Third-party logistics providers (3PLs): Must have a designated compliance contact and a written process for recording Receiving and Shipping CTEs at their facilities.

Phase 2: Structure Your Lot Codes for FSMA 204

Lot code design determines whether your chain-of-custody documentation holds up under an FDA investigation or breaks at the first carrier handoff.

TLC Design for FSMA 204 Audits

Design your TLC to be readable by both human auditors and automated systems. Link the TLC to the facility registry number of the TLC source location, the harvest or production date, and the product description. GS1 guidance recommends physical data carriers (barcodes, QR codes, or RFID tags) on two adjacent sides of packages and GS1 Serial Shipping Container Code (SSCC) tags on pallets as best practice for linking pallet-level identifiers to all TLCs in a mixed or single-product pallet. FSMA 204 itself is technology-neutral and does not mandate a specific data-carrier format.

Choosing Between Sequential, Date-Based, or Hybrid Codes

Sequential codes are simple to generate but lack operational context. Date-based codes are immediately readable by auditors but create collision risk for high-volume facilities producing multiple batches on the same date. Hybrid alphanumeric codes embed facility, date, and product context directly into the lot identifier, making them the practical choice for cold chain programs with multiple suppliers, mode changes, and temperature-sensitive FTL products.

Preventing Errors in TLC Program Setup

Three failures account for most TLC program breakdowns:

• Carrier-assigned lot codes: Establish in carrier agreements that carriers never assign new lot codes during transit.
• Unlinking the TLC from shipping documents: Every bill of lading, ASN, and transfer receipt must reference the original TLC.
• Manual entry errors at receiving: Barcode scanning reduces keying errors. Automated sensor capture removes the manual entry step that generates them.

Standardizing Traceability Lot Codes

Establish a central registry of active lot codes accessible to QA, warehouse operations, and IT. Every facility and supplier must use the same TLC format. Standardization prevents translation errors at handoffs and ensures that automated matching between inbound KDEs and internal records works without manual intervention.

Phase 3: Connect KDEs to Existing Digital Records

Most organizations already hold portions of the required KDE data across Enterprise Resource Planning (ERP), Warehouse Management System (WMS), and Transportation Management System (TMS) systems. The work is connecting, validating, and closing the gaps.

Inventorying Current Traceability Data

Audit your existing ERP, WMS, and TMS against the required KDE list for each CTE. Many organizations find that shipping KDEs exist in the TMS but receiving KDEs rely on paper-based bills of lading scanned as image files. Image files cannot be sorted or filtered within 24 hours. Classify each data source as structured (queryable), semi-structured (extractable with effort), or unstructured (paper-only).

Audit-Ready KDE Deficiency Analysis

Perform a gap analysis against the full KDE list for each CTE your organization performs. The 24-hour sortable spreadsheet requirement makes paper-based receiving records operationally infeasible at scale. Common KDE gaps include: exact time of receipt, location identifiers at intermediate warehouses, and condition data across carrier handoffs.

Creating KDE Capture Points at Each CTE

Configure your WMS and TMS to force structured data entry at the physical moment of each CTE, not at shift end. For temperature-sensitive FTL products, automated sensor-based capture removes the manual data entry step entirely. A global cellular, WiFi, and GPS tracker traveling with the shipment generates a continuous, timestamped condition record on a preconfigured transmission schedule, independent of carrier reporting. That record satisfies both the location and condition KDE requirements without manual data entry at any handoff point.

Validating KDE Inputs for FSMA Compliance

Configure automated validation rules in your WMS and TMS to flag incomplete records before archiving. Validation checks should cover TLC format compliance, timestamp completeness, required field presence, and quantity-unit-of-measure consistency. Route records that fail validation to a QA queue for rapid resolution rather than holding them until the next audit cycle.

Phase 4: Choosing Your Traceability Tech Stack

The systems you select determine whether your program produces a compliant sortable spreadsheet within 24 hours or requires a manual scramble under deadline pressure.

Choosing Systems for Food Traceability

Software selection for FSMA 204 traceability should prioritize: the ability to generate a sortable electronic spreadsheet (ESS) within 24 hours of an FDA request, structured data export via Application Programming Interface (API), connectivity to your existing ERP and WMS, and a receiving interface that warehouse operators can use without extended training. The Tive 2026 Buyer's Guide frames visibility investment against the cost of not having it, where absence of real-time location and condition data leads to spoilage, compliance exposure, and carrier disputes.

Integration Requirements for Multi-System Environments

In most mid-market operations, traceability data sits across at least three systems: shipping data in the TMS, receiving data in the WMS, and lot information in the ERP. When an FDA request arrives, that fragmentation becomes a 24-hour scramble. Tive's public REST API (v3) provides full read and write access. Real-time webhooks push tracker location and condition data directly into your TMS, ERP, and WMS as events occur, not on a batch cycle. Pre-built TMS integrations with Shipwell, Transporeon, Freightgate, FreightPOP, Turvo, and Tai reduce the IT effort required to connect condition data to existing transportation records.

Selecting FSMA 204 Software Options

Software-only transportation visibility platforms aggregate carrier-reported milestone data. They cannot satisfy the physical condition KDE requirements because they do not measure what is happening inside the shipment. Temperature deviation, humidity excursion, and shock impact require a physical sensor. The practical question is not which platform has more integrations but whether the condition data is first-party and sensor-based, or carrier-reported and subject to reporting delays. First-party data from a device the shipper controls is what survives an audit challenge when carrier records differ.

Maintaining 24/7 Traceability Records

FSMA 204 requires traceability records to be stored for a minimum of two years. Tive holds System and Organization Controls (SOC) 2 Type 2 and International Organization for Standardization (ISO)/International Electrotechnical Commission (IEC) 27001 certifications, addressing data security and access controls so traceability records are stored with the security standard FDA auditors expect from regulated food systems. FSMA compliance is confirmed; buyers with specific validation requirements should confirm the scope directly with Tive.

Tive Hardware Tracker Line-Up for Food Traceability

The Solo 5G adds humidity and shock data for high-risk lanes where a single excursion could cost $90,000 to $120,000 in spoiled product if undetected. Alpine Fresh caught two such excursions in time to act and prevented both losses.

Phase 5: Onboard Partners for FSMA 204 Compliance

Your traceability program is only as complete as the data your trading partners supply. Onboarding requires contractual clarity, standardized formats, and a receiving verification workflow.

Defining TLC and KDE Supplier Requirements

Draft supplier compliance agreements mandating TLCs and KDEs with every inbound shipment, delivered digitally before or at pickup. Specify the TLC format, required KDE fields, and acceptable transmission method: Electronic Data Interchange (EDI), API, or structured spreadsheet upload. Include chargeback or rejected-shipment consequences for non-compliance and apply them consistently to maintain accountability during peak season.

Standardizing FSMA 204 Data Protocols

Use GS1 standards and Electronic Product Code Information Services (EPCIS, an industry-standard format for sharing CTE and KDE data between organizations) to exchange traceability data across trading partners. EPCIS provides a common event schema that prevents translation errors when two organizations use different field names for the same KDE. Standardizing on these formats means partner onboarding requires configuration rather than custom development.

Verifying Inbound Traceability Data Accuracy

Establish a receiving protocol where QA reviews the digital KDE record against the physical shipment before the trailer is unloaded. Confirm the TLC matches the ASN, product description and quantity are consistent, and timestamps are complete. For temperature-sensitive FTL products, pull the condition log from the device and confirm the temperature record falls within the acceptable range before product enters cold storage.

Tracking Ongoing Traceability Compliance

Build carrier and supplier scorecards tracking KDE delivery rates, TLC consistency rates, and temperature excursion rates by lane and partner. Use scorecard data to structure corrective action conversations with underperforming partners and to demonstrate a good-faith compliance program to FDA investigators when a gap occurs despite proper protocols.

Phase 6: Pilot Testing for FSMA 204 Compliance

A structured pilot on a single high-risk lane surfaces documentation gaps, system failures, and carrier handoff blind spots before they become findings during an actual FDA inspection.

Conducting FSMA 204 Traceability Trials

Design your pilot around a single high-risk product lane: high-value produce, temperature-sensitive dairy, or a fresh seafood lane where a single excursion triggers a rejected load. Deploy Tive Solo 5G trackers on pilot shipments to capture real-time temperature and location data alongside the manual TLC and KDE records. The parallel data stream lets QA compare what the carrier reported against what the device measured, identifying handoff gaps before they become audit findings.

"The Tive trackers are invaluable to provide real-time and real-world shipping data. The live updates in the online app were great and worked as intended." - Verified user on G2

Meeting the 24-Hour FSMA Data Deadline

Run a mock audit during the pilot. Simulate an FDA phone request and measure how long it takes to generate a compliant, sortable electronic spreadsheet covering all pilot shipments. The FDA's sample spreadsheet includes separate tabs for each CTE, with all required KDE fields in each tab. Measure time to extract records from each system, merge data from multiple sources, verify completeness, and format and deliver the file.

Mock Recall and Audit Readiness Checklist

• Identify the TLC for the pilot lot and confirm it appears consistently across the Shipping CTE, Receiving CTE, and any Transformation records.
• Extract all KDE records for that TLC from your ERP, WMS, and TMS and confirm they merge into a single sortable spreadsheet without manual rekeying.
• Verify every timestamp is a full date-and-time stamp, not a date-only field.
• Confirm the condition log from the Tive tracker covers the full transit period without gaps. Verify that offline periods show backfilled data upon reconnection.
• Validate the electronic spreadsheet can be filtered simultaneously by TLC, CTE, date, and trading partner.
• Confirm the spreadsheet can be delivered to an external recipient within the 24-hour window from the simulated request.
• Document all bottlenecks, missing fields, and system failures encountered and assign Corrective and Preventive Action (CAPA) owners to each finding.

Cataloging Gaps in FSMA 204 Pilots

Document every failure during the pilot: missing lot codes at handoffs, unrecorded carrier transfers, temperature excursions that appeared on the device log but were not captured in any WMS or TMS field, and KDE fields that existed in one system but could not be exported in a sortable format. Each failure becomes a gap entry in the program improvement log with a root cause and a remediation action assigned.

E.T.H. Cargo's pharma case study demonstrates what gap-free continuous records look like in practice: five trackers simultaneously pinging at the same out-of-range temperature confirmed a cooling failure that a ground handler denied, settling the dispute with device data rather than conflicting verbal accounts.

Mapping Corrective Actions to Risks

Connect pilot findings to formal CAPA workflows. Operational risks require operational corrections: a reefer unit that stops cycling correctly is an equipment failure addressed by Smart Reefer Cycle Detection Alerts and a carrier maintenance protocol, not just a documentation update. Administrative gaps require process corrections: a missing handoff KDE is addressed by updating the WMS receiving workflow and retraining the dock team. Both categories need a documented owner, due date, and verification step before the gap is closed.

Overcoming FSMA 204 Traceability Hurdles

Even well-designed programs encounter implementation obstacles. The most common involve legacy data quality, supplier capability gaps, and manual entry points that introduce errors at scale.

Updating Legacy Data for Compliance

Start with clean master data in your ERP. Inconsistent product descriptions, duplicate supplier records, and missing facility identifiers create the mismatches that break automated matching between inbound KDEs and internal product records. FSMA 204's two-year retention requirement is prospective: once your program is live, every record you create under the compliance regime must be retained for at least two years from the date of creation. There is no regulatory requirement to retroactively digitize historical records that predate your compliance date. That said, resolving those master data issues before go-live is still operationally necessary. Confirm your specific retention obligations and any pre-compliance recordkeeping questions with your regulatory counsel.

Suppliers Unwilling or Unable to Provide KDEs

Small or technologically limited suppliers present the most common onboarding obstacle. A practical solution that does not require those suppliers to invest in new IT infrastructure is the Tive Tag, a paper-thin Near Field Communication (NFC)-enabled temperature label starting at $5 per tag. The supplier applies the Tag at origin. The receiver taps it with an NFC smartphone at delivery to capture a condition record that syncs to the Tive cloud, generating an audit-ready temperature log without requiring the supplier to operate any software. For administrative KDEs, provide simple structured spreadsheet templates with mandatory fields until the supplier can support EDI or API transmission.

Fixing Manual Data Entry Gaps

Manual barcode scanning and clipboard-based record-keeping create opportunities for errors at the exact moments FSMA 204 requires precise data capture. A mis-scanned lot code or a transcription error during receiving becomes an audit finding when the FDA cross-references your records against supplier data. Configure WMS receiving workflows to make manual override of system-suggested TLCs a logged, supervisor-approved action rather than a silent correction. Deploy sensor-based capture for condition data so temperature and location KDEs arrive in the system without human intervention.

The CYSPACK multi-zone monitoring approach, placing Solo 5G trackers and Beacons inside and outside thermal liners in the same container, demonstrates how automated sensor data simultaneously satisfies condition documentation requirements and removes the manual steps that generate entry errors.

Centralizing FSMA Compliance Records

A centralized dashboard where QA, logistics, and operations can access both administrative records and physical shipment condition logs in a single query is what makes a 24-hour FDA response possible. When traceability data lives in four systems and condition data lives in a separate folder of downloaded logger files, the 24-hour window becomes a crisis. The Tive Platform serves as the centralized repository for in-transit location and condition data, with that data pushed via API into the WMS and TMS records so both data types are accessible in the same lookup.

Compliance vs. Operational Reality

Key Guidance for FSMA 204 Program Adoption

Supplier onboarding, system integration, and pilot testing all require lead time. These principles help you sequence the work and avoid the gaps that surface closest to the deadline.

FSMA 204 Compliance Deadlines

The July 20, 2028, deadline is firm. Building a program that satisfies all six implementation phases requires meaningful lead time for planning and execution. Factor in supplier onboarding, system integration, pilot testing, and CAPA resolution when you set your internal timeline. Plan for a multi-quarter rollout, longer for global, multimodal supply chains. Organizations starting from limited or no formal traceability infrastructure in 2026 have approximately two years until the July 2028 deadline, which is enough time to execute correctly if implementation begins now. The retailers demanding two-hour traceability data will apply commercial pressure before FDA enforcement begins.

Watch Tive Highlights from LogiPharma 2025 for a current view of how compliance-driven cold chain operations are approaching visibility programs in regulated industries.

Handling 24-Hour Record Gaps

When a supplier or carrier fails to deliver required KDEs within the 24-hour audit window, document the gap immediately: log the timestamp of the request, the supplier's response or non-response, and the internal retrieval attempt. FDA investigators evaluating a program look for evidence of good-faith effort alongside actual compliance. A program with documented gap-response protocols and a corrective action history demonstrates operational seriousness even when individual records are incomplete.

Managing FSMA 204 Data Architecture

The ideal data flow for a compliant cold chain program runs as follows: Physical sensors capture location and condition data on preconfigured transmission schedules. That data transmits to the Tive cloud platform. Webhooks push it into your TMS and WMS in real time. Your ERP receives lot-level condition summaries via API or through a bridging TMS partner. No step relies on manual data entry or carrier-reported milestones, and every record is timestamped at the moment of capture, not at end-of-day batch processing.

Documenting FSMA 204 Traceability Data

Treat every shipment as a potential audit subject. Archive condition logs alongside KDE records, not separately. Ensure CAPA records reference the specific TLC that triggered the corrective action. Generate the 24-hour sortable spreadsheet at least once per quarter in a drill format so the team can execute it under pressure rather than learning the process during an actual FDA request.

Compliance with FSMA 204 sets the regulatory floor. Real-time condition monitoring during transit, with in-transit alerts reaching quality and operations teams via email, push notification, and Short Message Service (SMS), is what keeps product off the reject dock and out of the waste stream.

FAQs

What Is the FSMA 204 Compliance Deadline?

The federal compliance deadline is July 20, 2028. The FDA announced the 30-month extension in March 2025, with a proposed rule published in the Federal Register on August 7, 2025. Congress made that extension legally binding through appropriations legislation passed in November 2025. Retail contract terms in produce and perishables increasingly require faster-than-24-hour traceability data turnaround, ahead of the FDA's own deadline.

Which Foods Are on the FDA Food Traceability List?

The FTL includes leafy greens, fresh and fresh-cut herbs, cucumbers, fresh peppers, fresh tomatoes, fresh melons, tropical tree fruits, sprouts, fresh-cut fruits and vegetables, ready-to-eat refrigerated deli salads containing at least one FTL food, shell eggs, nut butters, soft and semi-soft cheeses, fresh and smoked finfish, crustaceans, and mollusks. Confirm your product scope against the full FDA FTL page, as the agency updates the list and associated guidance. Whether a multi-ingredient product incorporating an FTL food falls under the rule depends on the specific form and use of that ingredient. Confirm scope for borderline products with your regulatory counsel or current FDA guidance before excluding them.

What Is the Difference Between a CTE and a KDE?

A CTE is the supply chain event that triggers the requirement to record data, such as Shipping or Receiving. A KDE is the specific data field that must be captured at that event, such as the Traceability Lot Code, timestamp, quantity, and location identifier.

Can a Tive Tracker Automate KDE Capture for FSMA 204?

A Tive Solo 5G, Tive Solo Pro, or Tive Solo Lite tracker captures timestamped location and condition data on preconfigured transmission schedules and pushes that data into TMS and WMS systems via the Tive REST API (v3) and real-time webhooks, automating the capture of location and condition KDEs at Shipping and Receiving CTEs without manual data entry. The Solo Pro adds a built-in ePaper display showing current temperature and alarm status, enabling immediate accept/reject decisions at the dock without additional equipment.

How Does Real-Time Temperature Monitoring Relate to FSMA 204 Compliance?

FSMA 204 requires chain-of-custody documentation but does not mandate real-time condition monitoring. Real-time temperature monitoring produces the continuous, timestamped condition record that closes the audit gap between departure and arrival readings. It also issues in-transit alerts that let your teams act before a temperature excursion becomes a rejected load.

Key Terms Glossary

Critical Tracking Event (CTE): A supply chain event defined by FSMA 204 that triggers the requirement to capture Key Data Elements. The seven CTEs are Harvesting, Cooling, Initial Packing, First Land-Based Receiving, Shipping, Receiving, and Transformation.

Key Data Element (KDE): A specific data field that must be recorded at each Critical Tracking Event. KDEs include the Traceability Lot Code, product description, quantity and unit of measure, timestamps, location identifiers, and reference document numbers.

Traceability Lot Code (TLC): The single identifier connecting a product's origin to its final destination across every Shipping and Receiving CTE. The TLC must remain unchanged unless a Transformation event occurs.

Food Traceability List (FTL): The FDA-maintained list of food categories subject to FSMA 204 requirements. Categories include leafy greens, fresh and fresh-cut herbs, cucumbers, fresh peppers, fresh tomatoes, fresh melons, tropical tree fruits, sprouts, fresh-cut fruits and vegetables, ready-to-eat refrigerated deli salads containing at least one FTL food, shell eggs, nut butters, soft and semi-soft cheeses, fresh and smoked finfish, crustaceans, and mollusks. Confirm current scope directly with the FDA FTL page before finalizing your product inclusion decisions.

Electronic Sortable Spreadsheet (ESS): The file format the FDA requires you to produce within 24 hours of a traceability data request. It must be filterable simultaneously by TLC, CTE, date, and trading partner.

EPCIS (Electronic Product Code Information Services): An industry-standard format for sharing CTE and KDE data between trading partners. EPCIS provides a common event schema that prevents translation errors when organizations use different field names for the same data element.

Advance Shipping Notice (ASN): A digital document transmitted by a supplier before or at pickup that contains the TLC and corresponding KDEs for an inbound shipment. ASNs allow receiving teams to validate traceability data before the trailer is unloaded.

Corrective and Preventive Action (CAPA): A formal process for documenting the root cause of a compliance gap, the corrective action taken, and the preventive measure implemented to stop recurrence. CAPA records must reference the specific TLC that triggered the finding.

Temperature Excursion: A deviation from the defined acceptable temperature range for a food product during storage or transit. Under FSMA 204, an unrecorded temperature excursion during a carrier handoff constitutes a chain-of-custody gap.

Chain of Custody: The documented, unbroken record of every entity that held or transferred a food product from origin to final destination. A complete chain of custody maps each CTE to the corresponding TLC and KDE set, and is the primary evidence FDA investigators examine during a traceability inquiry.
