FDA traceability lot code overview
Primary US source used for the general relationship between lot identifiers and linked records; applicability to bottled water and a destination must be confirmed.
Connect the printed code to a usable production record
A visible date or lot mark supports traceability only when its content, source, readability and link to controlled production records are defined.
Direct answer
First confirm the code content and record requirements with the responsible quality and destination-market parties. Then select a marking method from the actual PET bottle, cap, label, film or carton substrate, available print area, surface condition, line speed and environment. Define how date, time, line, product and lot data reach the coder, who can change them, how the first code is approved and how unreadable or incorrect codes are detected and contained. Finally, link the printed identifier to material lots, process records, quality release and distribution records. A printer can apply a mark, but the plant traceability procedure gives that mark meaning.
System focus 01
List the information required on each packaging level and distinguish consumer-facing text from internal traceability identifiers. State the lot-creation rule, time zone, date format, product code and line identity, while avoiding unsupported universal shelf-life values. Map the identifier to production, material, sampling, hold, release and distribution records. Local label and record requirements need qualified confirmation before artwork or coding logic is approved.
System focus 02
Compare marking methods using approved samples at the intended code location. PET, labels, caps, flexible film and cartons can require different contrast, adhesion, energy and handling. Record line speed, product spacing, vibration, condensation, washdown, dust, ambient temperature and installation space. Review consumables, extraction or guarding where applicable, cleaning access and the effect of a coding stop on production.
System focus 03
Manual entry can be suitable for a limited operation, but it needs independent verification and restricted access. Automated data transfer needs a defined source, field mapping, communications response and fallback. Build product recipes that include code format and position and require first-off approval after start-up or changeover. The system should prevent or clearly alarm an expired, incomplete or unapproved coding job.
System focus 04
Define what constitutes an acceptable code for the selected substrate and downstream use. Checks may be periodic manual inspection or automated vision depending on risk and line design. If automatic inspection is used, specify the field or pattern checked, threshold, product tracking, reject mechanism and reject confirmation. Repeated failures should trigger a controlled response so incorrectly coded product is not simply accumulated elsewhere.
System focus 05
Commissioning should prove correct triggering, code content, position, changeover and stop-restart behavior with representative packaging. Traceability verification then follows selected finished units back to the related production and material records and forward to the first distribution records held by the plant. Record gaps and corrective actions through a controlled exercise. This technical guide does not decide which regulations apply or whether a particular market requires a code on a specific surface.
Coding and traceability brief
Use this matrix before selecting a printer or approving a packaging artwork revision.
| Control area | Question to settle | Required evidence | Failure response |
|---|---|---|---|
| Code definition | What identifies the product and lot? | Approved code and lot rule | Hold unidentifiable product |
| Application | Which substrate, location and line state? | Representative print trial | Stop, adjust and segregate |
| Verification | How is correctness and readability checked? | First-off and routine records | Reject and contain affected window |
| Traceability | Which records link backward and forward? | Completed trace exercise | Investigate and close record gaps |
Code content, retention and traceability duties must be reviewed against the actual product, plant and destination requirements.
Technical reading
Confirm the standards, guidance and legal requirements that apply to the project location and product before final design.
Primary US source used for the general relationship between lot identifiers and linked records; applicability to bottled water and a destination must be confirmed.
Equipment-industry source used to frame substrate, speed, code-content and integration decisions without recommending a product.
Buyer questions
Use these answers as a project-planning starting point. Final equipment and performance remain subject to the confirmed brief.
Not automatically. A date can form part of a lot identifier, but the plant must define how the printed code links to a specific production segment and its materials, quality and distribution records.
The position follows applicable requirements, substrate suitability, readability, permanence, consumer use and line access. Multiple packaging levels may carry related but different identifiers.
Manual entry may be possible, but access, independent verification, first-off approval and error containment should be defined. Automated transfer can reduce entry risk only when the source and interface are controlled.
No. A camera can verify selected visible features, but traceability also requires a lot-definition rule and linked production, material, release and distribution records.
Deep technical guides
Each guide answers one narrower project question and links the result back to complete-line scope.
A reliable hold-and-release workflow makes product status unmistakable in the warehouse, production record and business system while the evidence for disposition is still incomplete.
A mock recall should test whether the business can make and execute a product-protection decision under time pressure, not merely demonstrate that one shipment record can be found.
Laser and inkjet coders should be compared on substrate response, required code content, line speed, permanence, contrast, consumables, extraction and integration. The best technology depends on whether the code is placed on cap, bottle, label, film or case.
