The Wenzhou Gcseal Co. Ltd bolt seal is a heavy‑duty security device for container doors. It locks by finger pressure and can be removed only with a bolt cutter. The body is carbon steel, hot‑dip galvanized for corrosion resistance. An ABS plastic cover shields the mechanism and can be supplied in any colour on request. Each seal carries a sequential number settable up to seven digits, enabling unique traceability.
The product meets ISO/PAS 17712, the global standard for freight‑container seals, and is accepted by U.S. customs. One carton holds 250 units and weighs 34.32 lb (15.6 kg). In the industry, bolt seals typically range from M12 to M30 in bolt diameter and are expected to sustain tensile forces of at least 2000 N. Standard operating temperature for similar seals is -20 C to +80 C.
Shipping lines, freight forwarders and customs agents use these seals to deter tampering and verify cargo integrity. Buyers should confirm MOQ, lead‑time and incoterm directly with the supplier, noting the listed response rate is zero.

Before placing an order, verify that the seals carry the ISO/PAS 17712 certification and that the sequential numbering system meets your tracking requirements. Ask the supplier to provide material test reports confirming the carbon‑steel composition and galvanising thickness, as these factors affect durability in a marine environment.
Confirm the preferred incoterm, typical lead‑time and any minimum order quantity directly with the supplier, because the listing does not disclose these details. Clarify payment terms and whether a bank guarantee or documentary credit is required, especially for first‑time transactions.
Arrange for a third‑party inspection at the factory or upon loading to check seal dimensions, material quality and proper numbering. Request a conformity certificate and a packing list that records the carton weight of 34.32 lb (15.6 kg) for each shipment. Documentation such as a test report for tensile strength will help smooth customs clearance.
