Import Bolt Seal With Barcode Seals For Containers — Buy in Bulk from Supplier in China

Shandong Yutong Commercial Trading Co., Ltd. offers the YTBS001 model high security bolt seal, engineered for container, truck, trailer, van truck, and tank truck applications. The seal pin and bush are fabricated from Q235A steel, a carbon structural grade with typical yield strength of 235 MPa, while the outer cover uses ABS polymer for impact resistance and weather protection. Laser printing accommodates company names, bar codes, or sequential numbers directly on the seal body. The standard pack configuration ships as 10 pieces per box and 25 boxes per carton.

Q235A steel is the standard Chinese structural grade equivalent to ASTM A36 in general mechanical properties, though actual tensile performance should be verified against mill certificates for each batch. The ABS cover provides chemical resistance against fuels, salts, and UV exposure typical of maritime and overland transit environments. Barcode integration enables automated scanning at port gates and warehouse management systems, reducing manual inspection time. The spring-loaded locking mechanism, once engaged, requires bolt cutters for removal, leaving clear tamper evidence. No coating specification is stated for the steel components, so corrosion protection in saline environments should be confirmed with the supplier.

Freight forwarders, customs brokers, and logistics operators across export-import corridors represent the core buyer segment for this SKU. Applications span ISO container doors, trailer rear doors, tanker manlids, and bonded warehouse enclosures where C-TPAT or AEO programs mandate high security seal compliance. Buyers should confirm ISO 17712:2013 certification status and request test reports for pull strength, shear resistance, and anti-pick performance. The supplier's research group claims development across seven product series, suggesting in-house design capability, though production capacity and third-party audit status are not stated.

Shandong Yutong Commercial Trading Co., Ltd. operates from Wanda Office J2-503/504 in Jinan, Shandong Province, postal code 250000, with manufacturing activity cited in Dezhou city within the same province. The supplier holds a harbor trust tier, indicating baseline marketplace verification without premium accreditation. The response rate registers at 0.00 percent with zero average response hours recorded, signalling that buyer enquiries through platform channels may go unanswered. The company profile positions itself as both manufacturer and exporter across security seal categories including plastic seals, bolt seals, cable seals, and meter seals.

The supplier's claimed research group has developed seven product series encompassing over 100 individual types, suggesting breadth rather than specialisation in container security hardware. No specific factory size, annual output, or OEM client references are provided in the available profile. The listing does not state ISO 17712 certification, C-TPAT membership, or third-party laboratory accreditation, all of which would strengthen buyer confidence for customs-compliant applications. Buyers should independently verify manufacturing location, quality system documentation, and whether laser marking is performed in-house or subcontracted.
