Airline Catering Security Seals: A Verifiable Dispatch and Handover Checklist

Key takeaways

• A seal is evidence of a controlled handover, not a substitute for an approved aviation-security procedure.
• Buyers should specify the seal, the numbered record and the exception workflow together.
• Fit and breakage tests on the actual catering cart or container are more useful than a generic “tamper-proof” claim.

Airline catering passes through production, dispatch, transport, ramp handover and aircraft loading. A broken or unrecorded seal at any of these points can create an avoidable security investigation and a service delay. The procurement question is therefore not simply “Which plastic seal is cheapest?” It is “Can the operator identify who secured each unit, when custody changed and what happened when the condition did not match the record?”

IATA’s 2025 supporting guidance for aircraft-operator and supplementary security programmes discusses catering security and the protection of supplies during preparation, dispatch and transport. It treats tamper-evident sealing and validation within a broader security process. The operator and the applicable national rules determine the actual procedure; the document is not a certificate for a particular XHANCO seal.

ICAO’s 2025 USAP-CMA protocol questions ask reviewers to examine national-level security controls for catering, stores and supplies through aircraft loading. Where a State uses a regulated or known supplier process, the questions refer to tamper-evident seals or physical protection for vehicles and containers transporting in-flight supplies. This is oversight guidance, not a universal product specification or approval of any particular seal.

What should be controlled at dispatch?

A usable dispatch record connects the physical seal to a specific cart or container. Record the flight or service reference, unit identifier, seal type and unique number, dispatch location and time, and the name or ID of the person applying it. Before a unit leaves the controlled area, a second check should confirm that the closure engages correctly, the number is legible and the record matches the unit. If a seal has been replaced, preserve the old number and the reason for replacement rather than overwriting the original entry.

Transport and receiving teams need a corresponding handover check. The receiver compares the unit ID and seal number with the dispatch record and notes whether the closure is intact. An exception should stop the routine handover and follow the airline or caterer’s approved escalation process. The record should capture who found the discrepancy, the time, the unit status, any inspection and the authorised disposition. A photograph may help document condition, subject to the operator’s privacy and security rules; it does not replace the written custody trail.

Two product applications that need different specifications

For a cart latch or container closure, XHANCO lists a 230 mm numbered disposable PP security seal. Sequential numbering can support reconciliation, while barcode or QR printing may support scanning if the customer defines a compatible code format. Before ordering, test the seal on the actual latch: the usable length, locking-head clearance, pull direction, number visibility and removal method all matter. Do not infer suitability from the 230 mm nominal length alone.

For a different attachment geometry, XHANCO lists 40 × 60 mm custom-printed hang-tab security seal tags. A tag can carry a unit reference or handover identifier where a hanging format is operationally convenient. Buyers should validate attachment strength, print readability and whether the tag’s loss or removal would be apparent during the receiving inspection. Neither listing establishes approval for every airline’s security programme; a customer trial and written acceptance are necessary.

A procurement and validation checklist

1. Map the custody points. Identify where the cart or container is closed, transferred, received and opened. Define who can apply or replace a seal.
2. Specify the physical interface. Supply photographs and dimensions of the latch or aperture, the expected handling route and any cold, moisture or cleaning exposure.
3. Define identification. Choose number length, uniqueness, print contrast, barcode/QR symbology if needed, and how unused or damaged numbers are controlled.
4. Run a representative trial. Test fitting and removal with gloved staff, assess accidental breakage in normal transport, and check whether deliberate interference leaves an observable discrepancy.
5. Test the record. Reconcile issued, used, rejected and returned numbers against the dispatch and receipt logs; record how discrepancies are escalated.
6. Approve the final sample. Keep a signed reference sample and written acceptance criteria for production inspection and future reorders.

The GS1 EPCIS standard offers a useful model for digital event records—the object, time, place and business step associated with a movement. EPCIS is an optional data-design reference here, not an IATA requirement for catering seals. A simpler controlled log may be entirely appropriate if it meets the operator’s programme and provides reliable reconciliation.

Current obligations versus future changes

As of 25 October 2026, buyers should work from their airline’s current approved security programme, local regulatory requirements and the caterer’s documented procedure. There is no universal future phase-in date for one seal material, QR format or EPCIS workflow in the sources cited above. If a tender refers to a future implementation milestone, request its exact authority and effective date before incorporating it into the product specification.

The practical result is a narrow but valuable purchasing brief: a seal that fits the unit, an identifier that survives the workflow, and a record that makes exceptions visible. For samples of the two formats above or a fit trial against your actual cart, send XHANCO the latch drawing, intended use and validation criteria. We can discuss a sample specification without implying that a product alone certifies your security process.
