Import Bolt Seal — Buy in wholesale FOB from Supplier in China

HeBei XuanYi import and export Co.,Ltd. supplies bolt seals constructed from hardened carbon steel with a zinc alloy lock body, designed for locking shipping containers and cargo during transport. The seal meets ISO 17712 standards for international trade compliance, providing tamper-evident protection through a unique stamped identification number on each unit. The standard size suits most container and trailer doors, with colour coding available for easy identification and security protocol compliance. The hardened steel construction resists cutting and tampering, while the locking mechanism provides visual indication of any interference attempt.

The material combination of hardened carbon steel shackle and zinc alloy lock body balances shear strength with manufacturing economy. Hardened carbon steel typically achieves Rockwell hardness in the C-scale range suitable for resisting bolt cutters and hacksaws, while the zinc alloy housing provides corrosion resistance and accepts clear laser or mechanical marking for identification numbers. Colour options allow fleet operators and logistics providers to implement visual coding systems for route identification, cargo type, or security level. The ISO 17712 compliance ensures the seal meets mechanical strength requirements for high-security applications, including tensile strength and bending resistance thresholds specified in the standard.

Primary applications span ocean freight container sealing, trucking trailer security, and rail cargo protection, serving freight forwarders, customs authorities, and logistics operators worldwide. Warehousing operations handling high-value goods also deploy these seals to maintain chain of custody. Buyers should confirm with HeBei XuanYi import and export Co.,Ltd. the specific ISO 17712 edition certified, available colour options, and whether the stamped identification numbers are sequential, randomised, or customisable. Packaging configurations for bulk supply and applicable Incoterms require direct negotiation with the supplier.

HeBei XuanYi import and export Co.,Ltd. is based in Hebei Province, China, and operates under organic supplier tier with harbour trust tier classification. The company profile shows a zero percent response rate and zero average response hours, indicating either limited platform activity or a newly established listing with minimal transaction history. No specific address, factory location, production capacity, workforce size, or year of establishment is disclosed in the available profile information.

The supplier positions itself as an import and export company offering bolt seals for supply chain security applications, with flexible minimum order quantities and distribution through FOB or CIF shipping terms. The listing does not state quality management system certifications such as ISO 9001, nor does it detail manufacturing processes for the hardening and marking operations. Buyers should independently verify the supplier's export licence status, ISO 17712 certificate validity with the issuing body, and any third-party audit reports before committing to large-volume contracts. Direct engagement with HeBei XuanYi import and export Co.,Ltd. is essential to assess technical competence and reliability.
