For international container transportation, security seals play an important role in cargo protection, shipment traceability, and customs inspection procedures. Shipping companies, freight forwarders, and logistics operators need seals that provide reliable locking performance, permanent identification, and compliance with recognized security standards.
Our ISO 17712 High Security Cable Seals are designed for securing ISO containers, trailers, and high-value cargo shipments where stronger protection and traceable identification are required.
Manufactured with high-strength galvanized steel cable and a durable locking mechanism, these seals are suitable for international freight applications, including ocean transportation, customs-controlled shipments, and intermodal logistics.
As a direct security seal manufacturer, we provide bulk supply and OEM customization services for shipping companies, logistics providers, security seal distributors, and industrial customers worldwide.
