Container Seals
Container Seals
Container seals play a crucial role in international and domestic freight security. They ensure cargo integrity from the moment a container is packed to its final delivery, in accordance with international carrier and regulatory standards (ISO PAS 17712:2013).
What Are Container Seals?
Container seals are tamper-evident devices placed on the container doors once loading is complete. Each seal carries a unique serial number, which must be recorded on all key shipping documents, such as the bill of lading and shipping instructions.
An anti-tamper mechanism, it is designed to only be used once, verifying contents is free from alteration, theft and contamination while in transit.
ISO 17712:2013 Standard
All high-security container seals must comply with ISO 17712:2013, the internationally recognised standard for mechanical freight container seals. Under this standard, seals are classified into three types: “H” – High Security, which is required for international freight; “S” – Security; and “I” – Indicative. Champion Freight recommends using High Security (“H”) bolt seals for all export containers, as they are designed to resist tampering and meet international regulatory expectations, including the U.S. Customs-Trade Partnership Against Terrorism (C-TPAT) and similar global programs.
SES (Secure Export Scheme) Seals
Champion Freight also uses SES (Secure Export Scheme) seals for exports under New Zealand’s Secure Export Scheme. SES seals function in a similar way to standard container seals. They are applied after the container is loaded and remain in place throughout transit.
SES seals gives exporters confidence that their shipments meet all New Zealand export security standards while helping to streamline customs clearance.
Why Do I Need A Container Seal?
Seals provide assurance that containers remain secure and unopened throughout transit. They help maintain cargo integrity across every stage of the supply chain and ensure compliance with international shipping and customs requirements.
Using compliant seals not only safeguards cargo but also streamlines customs clearance and reduces the risk of delays, penalties, or security holds. Champion Freight’s team ensures your shipments meet all international and New Zealand requirements for container security and documentation.
Who Is Responsible for Using a Container Seal?
The responsibility for applying a container seal lies with the shipper or their authorised agent. Once loading is complete, the container must be sealed immediately and before it leaves for transport. The seal should always be affixed prior to dispatch, whether for coastal or international shipping. Each seal carries a unique serial number, which must be clearly recorded on all relevant shipping documents and verified at each stage of handling to ensure full traceability and compliance.
