Import Anti-Spin Container Bolt Lock Security Seal — Buy in Bulk from Supplier in China

The Anti-spin Container Bolt Lock Security Seal from Shandong Bochuang Seal Co., Ltd. is a high-security mechanical seal designed to prevent tampering with shipping containers during transit. It features a bolt-and-lock mechanism that resists spinning or removal without visible damage, ensuring the integrity of the container’s contents. The seal is typically manufactured from hardened steel or zinc alloy, providing durability and resistance to cutting or tampering tools.

Bolt seals like this are standard in the logistics industry for securing intermodal containers, trailers, and trucks. They are often color-coded for easy identification and may include unique serial numbers or barcodes for tracking. Standard dimensions include a bolt diameter of 6 mm to 8 mm and a total length of 50 mm to 70 mm, with a typical tensile strength of 1,200 kg or more to prevent forced removal. The locking mechanism is designed to snap into place permanently, requiring bolt cutters for removal.

Primary buyers include freight forwarders, shipping lines, and customs authorities who require tamper-evident security for international cargo. The seals are suitable for one-time use and are discarded after the container is opened. Shandong Bochuang Seal Co., Ltd. offers flexible trade terms, including a minimum order quantity of 1 piece, but buyers should confirm packaging, lead time, and Incoterms (e.g., FOB Qingdao) directly with the supplier, as these are not specified in the listing.

Shandong Bochuang Seal Co., Ltd. is a manufacturer specializing in security seals, including container bolt seals, lead seals, cable seals, plastic seals, and high-security seals. The company is located in Qingyun County, Shandong Province, a region recognized as a major production hub for seals in northern China. Its facility covers over 6,500 square meters and employs more than 160 workers, including 15 professional personnel dedicated to production and quality control.

The supplier’s profile highlights its focus on producing seals with competitive pricing, short delivery times, and a low MOQ (as little as 1 piece). However, the listing does not provide details on certifications, such as ISO 9001 or C-TPAT, which are often required for security seals used in international shipping. Buyers should request verification of compliance with industry standards, as well as samples to test tamper resistance and durability before placing bulk orders.
