In international logistics, sealing containers, trailers, warehouses and cargo holds is essential to protect shipments from unauthorized access and ensure cargo integrity. A seal is not simply a locking device; it is an indicator of security, compliance and accountability throughout the entire transportation chain. Therefore, sealing and seal-breaking operations must be performed in accordance with global regulations, accurately documented and verified. At Kuzey Marine Survey, we manage these operations with strict adherence to international standards to minimize security risks and ensure shipment transparency.

Before sealing begins, the cargo type, container structure, transportation route and involved parties are evaluated. Our surveyors first inspect any existing seals, recording their number, specifications and physical condition. When applying new seals, ISO 17712 high-security seals are selected. After installation, seal numbers, application points, date-time logs and party details are recorded and reported. All steps are photographed and digitally archived to maintain complete traceability.

Depending on cargo type and security requirements, additional sealing methods may be applied such as dual sealing, cable security seals, container safety locks and reinforced sealing procedures. Our surveyors verify the seal’s durability and tamper resistance to ensure that cargo integrity remains intact throughout the transport.

Seal breaking is a highly sensitive process and must only be performed by authorized personnel. Before breaking the seal, its identification, condition, tamper marks and authenticity are examined. Once the seal is broken, the container or cargo hold is opened under supervision, and the condition of the cargo is inspected. Any damage, shortage, moisture or irregularity is documented.

A detailed sealing and seal-breaking report is then issued for shippers, consignees, customs authorities, insurance companies and logistics operators. These reports hold legal validity and play a critical role in resolving disputes and verifying transportation accuracy. Kuzey Marine Survey ensures every step is handled according to industry standards, providing clients with complete operational secu
