Overview
This template is a C-TPAT container and trailer seal inspection log for documenting the security checks that happen before a sealed load is accepted, transferred, or released. It captures inspection details, equipment identification, the 7-point container or trailer inspection, high-security seal control, and any discrepancy or escalation that affects release.
Use it when your process requires proof that a container or trailer was checked for tampering indicators, that the seal number matched the shipment record, and that the seal was applied or removed at the correct time and location. It is especially useful for outbound export loads, cross-dock transfers, carrier handoffs, and any shipment where custody must be traceable. The form supports a clear audit trail by tying the inspection to a shipment reference, SOP, inspector identity, and release authorization.
Do not use this template as a general freight damage report or a substitute for a full cargo security program. It is not meant for loose pallet checks, non-sealed local deliveries, or inspections where the equipment is not a container or trailer. If a seal is missing, broken, mismatched, or the equipment shows tamper evidence, the log should capture the exception and prevent release until the issue is resolved. The strongest use of this template is real-time documentation at the dock, before the shipment leaves controlled custody.
Standards & compliance context
- This template supports C-TPAT cargo security expectations by documenting container integrity checks, seal control, and custody traceability.
- The 7-point inspection structure aligns with common supply chain security practices used in customs and carrier security programs.
- If your site operates under broader warehouse or transportation controls, the log can support internal procedures tied to ISO 9001:2015 document control and non-conformance handling.
- For regulated food, pharmaceutical, or high-value shipments, the form can be paired with customer SOPs and chain-of-custody requirements without replacing product-specific compliance records.
- Any tamper evidence, seal discrepancy, or document mismatch should be treated as a security non-conformance and escalated under your site procedure.
General regulatory context for orientation only — verify current requirements with counsel or the relevant agency before relying on this template for compliance.

High-Security Seal Control
This section documents the seal as a controlled security device, including its number, condition, custody, and application or removal timing.
- Seal number recorded and legible
- Seal type meets high-security seal requirements
- Seal applied at authorized location and closed properly
- Seal condition is intact with no evidence of tampering
- Seal application or removal date and time recorded
- Seal custody transfer documented when applicable
Discrepancies, Exceptions, and Release

- Corrective action or escalation documented
- Shipment released only after inspection completion and authorization
- Inspector signature
How to use this template
- Enter the inspection date, time, inspector name and role, shipment reference, inspection type, and the SOP or shipment instruction that governs the check.
- Record the container or trailer number, carrier name, equipment type, and seal location, then confirm the identification matches the shipping documents.
- Walk the 7-point inspection in order and document observable tampering indicators, damage, repairs, holes, concealed access points, or intrusion signs for each area.
- Record the seal number, seal type, application location, condition, and custody transfer details, and attach photos of the equipment identification and any defects if your process requires them.
- Document any discrepancy, exception, or corrective action immediately, then release the shipment only after the inspection is complete and authorization is recorded.
- Sign the log and route it to your retention or audit file so the inspection record is available for customer review, internal review, or security audits.
Best practices
- Inspect the container or trailer in the same sequence every time so missed areas are less likely.
- Record the seal number while the seal is in view and legible, not from memory after the inspection.
- Treat any mismatch between the seal record, shipment documents, and equipment ID as a hold condition until resolved.
- Photograph the equipment identification plate, door markings, and any tamper evidence at the time of inspection.
- Use clear, observable language such as fresh welds, pry marks, bent hinges, or concealed access points instead of vague comments.
- Document who transferred custody of the seal whenever the seal changes hands, including the time and reason.
- Do not release the shipment until the inspection is complete and the authorization field is filled in.

Common use cases
Frequently asked questions
What does this C-TPAT Container and Trailer Seal Inspection Log cover?
It covers the inspection details, equipment identification, the C-TPAT 7-point container or trailer check, high-security seal control, and final release documentation. The log is designed to capture whether the container or trailer shows tampering indicators, whether the seal is correct and intact, and whether any discrepancy was escalated before shipment release. It is a record for security verification, not a general freight condition report.
When should this log be used?
Use it before loading, after loading, at handoff points, and before dispatch when a shipment requires seal verification or C-TPAT-aligned security controls. It is also useful when custody transfers between warehouse, carrier, and cross-dock teams need a traceable record. If the move does not involve sealed containers or trailers, a different inspection form may be more appropriate.
Who should complete the inspection?
A trained inspector, warehouse lead, shipping supervisor, or other authorized employee should complete it, depending on your SOP. The person signing should be able to recognize tamper indicators, confirm seal integrity, and stop release when a discrepancy is found. If your process requires a second review, the log can capture both the inspector and the authorizing reviewer.
How often should the inspection be performed?
It should be completed every time a sealed container or trailer is received, loaded, transferred, or released under your security procedure. Many organizations also use it whenever a seal is replaced, a shipment is reworked, or a load is held for exception review. The right cadence is driven by your SOP, customer requirements, and site security controls.
Does this template replace a full cargo security program?
No. It documents one control point inside a broader cargo security process, including seal management, access control, and shipment verification. It helps create evidence that the inspection happened, but it does not replace training, approved seal inventory control, or carrier vetting. Use it as part of your operating procedure and audit trail.
What are the most common mistakes when using this log?
Common mistakes include recording a seal number without confirming it is legible and intact, skipping the undercarriage or roof check, and releasing the shipment before an exception is resolved. Another frequent issue is documenting the inspection after the trailer has already moved, which weakens the chain of custody. The log works best when the inspection is done in real time and every discrepancy is tied to a corrective action.
Can this template be customized for different carriers or facilities?
Yes. You can add carrier-specific seal rules, site-specific release approvals, dock door references, or photo fields for your equipment. Many teams also customize the form to match their SOP language, include customer shipment references, or add a second sign-off for high-risk loads. The core structure should still preserve the 7-point inspection and seal control fields.
How does this log support audits and compliance reviews?
It creates a dated record showing who inspected the equipment, what was checked, what seal was applied or removed, and whether any exception was escalated. That makes it easier to demonstrate consistent execution during customer audits, internal reviews, and security assessments tied to C-TPAT expectations. It also helps show that release decisions were made only after inspection completion.
