Tamper-Evident Security Seals & Bags

The consumable chain-of-custody layer: Security Tamper-Evident Bags (STEBs) for liquids bought airside, tamper-evident seals for air cargo, catering trolleys and bonded stores, security tapes, labels and identification ties. Governed by ICAO/IATA STEB standards and air-cargo secure-supply-chain regimes (RA3/ACC3 in the EU model), these are high-volume recurring purchases rather than capital assets, bought by airlines, caterers, ground handlers and duty-free operators as well as airports. A distinct, consumables-driven sub-category with its own specialist manufacturers and a procurement cadence measured in pallets per month, not refresh cycles.
