What to Do When a Broken Seal Is Found?
Broken seal response protocol.
Direct answer
When a broken, missing or suspicious security seal is found, the first step is not to automatically conclude that theft occurred. Preserve the condition of the cargo or control point as far as practical, document the serial number and physical findings, notify the authorized person and initiate the organization's exception/deviation procedure. If resealing is required, link the old and new serial numbers in the same event record.
What you will learn
A broken seal is an event indicator; by itself it is not proof of theft or product compromise.
Photograph the seal and closure point before further handling where practical.
Record serial number, location, date/time, handover parties and cargo identity.
Unauthorized personnel should not simply fit a new seal and close the event.
If resealing occurs, preserve the old-to-new serial chain.
What does a broken seal mean?
A broken seal does not point to only one conclusion. Causes may include undocumented authorized opening, incorrect application, mechanical transport damage, accidental cutting or genuine unauthorized interference. Incident handling should therefore collect evidence and compare process records rather than assume a cause.
For food, pharma, chemical or high-value cargo, a broken-seal event may trigger a product safety/quality procedure, but final product disposition should be decided by the authorized team using temperature, packaging, quantity, access and other quality evidence.
Evidence to collect for a broken/suspicious seal
| Record | Example | Why needed |
|---|---|---|
| Seal identity | Serial, model, color | Identifies the expected physical control |
| Photo | Body, wire/strap/pin, closure point | Preserves the condition at discovery |
| Time and location | Date/time and warehouse/gate/vehicle location | Narrows the incident timeline |
| Chain of custody | Last inspector, sender, receiver | Shows responsibility and touchpoints |
| Cargo/asset identity | Order, vehicle, container, meter, lot | Defines incident scope |
| Replacement seal | New serial and authorized person | Restarts the control chain |
What not to do during a suspicious event
- Discarding the broken seal before photos and records are taken
- Silently overwriting the old serial number with the replacement
- Allowing unauthorized personnel to open or reseal the cargo on their own decision
- Treating a broken seal alone as definitive proof of theft
- Closing the incident without reviewing other records such as temperature, weight, CCTV or handover data
Broken-seal incident response flow
- 1
Preserve the condition
Where security and safety permit, keep the cargo/door in its discovered condition at the inspection point.
- 2
Document
Record serial, photos, time, location, cargo and handover parties.
- 3
Notify the authorized role
Escalate to the responsible security, operations, quality or customs role defined by procedure.
- 4
Investigate and decide
Compare documents, prior seal checks and relevant operational records; let the authorized role decide on opening, quarantine or other disposition.
- 5
Reseal if required
Link the new serial number to the old serial and incident record to start a new chain.
Frequently asked questions
Does a broken seal mean theft?
No. Unauthorized interference is one possibility, but accident, incorrect application or undocumented authorized opening can also be causes. Investigate the event.
Should the broken seal be retained?
Depending on risk and procedure, the physical seal may be retained for a defined period or documented through detailed photographs.
Can a new seal be applied immediately?
After authorized disposition and necessary evidence capture, a replacement may be applied if operations need to continue. Link the new serial to the original event.
Should the product be quarantined?
This depends on product, risk and quality/security procedure. The authorized team should perform a risk assessment especially for regulated or high-value cargo.
How should the system record be kept?
Do not delete the old serial. Keep event type, cause/outcome, photos, user and any replacement serial as an auditable history.
