Import Bolt Seals — Buy in Bulk from Supplier in China

Bolt seals from Shandong Bochuang Seal Co., Ltd. are tamper-evident security devices made from high-grade Q235A low carbon steel pins and bushes with ABS plastic housings. The standard dimensions are 74mm in height and 8mm in shaft diameter, designed for secure closure of shipping containers, trailers, railway wagons, and vans. Each seal is laser printed or hot stamped with custom markings and available in blue, yellow, green, white, or customized colors to support fleet identification and audit trails.

The steel components meet standard tensile strength requirements exceeding 14kN, ensuring resistance to forced removal. The ABS housing provides impact resistance and weather durability under outdoor storage and transport conditions. These seals are not reusable and are designed for single-use applications where chain-of-custody integrity is critical. The material combination is typical for industrial bolt seals in global logistics, balancing strength, cost, and ease of inspection.

These seals are purchased by freight forwarders, port authorities, customs agencies, and logistics operators managing high-value or regulated cargo. They are packed 10 pieces per box, with 25 boxes per carton (250 seals per carton), and packaging can be adjusted to plastic or paper boxes upon request. Trade terms are typically FOB Qingdao or Tianjin, with minimum order quantities negotiable based on color and printing requirements.
