Shandong Haoyu’s high-security seals, certified under ISO 17712, have become the industry benchmark for safeguarding high-value goods such as electronics, pharmaceuticals, and luxury items during transit. Unlike traditional locks, these seals feature tamper-evident designs and unique serial numbers, making unauthorized access immediately detectable. Logistics firms in Europe and the U.S. report a 60% reduction in theft incidents after adopting Haoyu’s seals, which are also compliant with C-TPAT (Customs-Trade Partnership Against Terrorism) standards for international shipments.
