A container collected in Rotterdam may continue by truck, barge or rail before reaching a distribution centre. At each handover, the next operator needs a clear record of its seal identity and condition.
ISO 17712 certified seals can support that process. Choosing the right seal starts with understanding the application, the required security classification and the documentation behind the exact product.
Why seal verification matters in the Netherlands
Rotterdam’s container throughput was broadly unchanged in the first half of 2026, falling 0.1% in TEU. Within that total, deepsea volumes increased by 5.2%, while transhipment declined by 20% amid capacity constraints. The port expected additional terminal capacity from late 2026.
For logistics teams managing changing flows, a repeatable handover procedure helps keep seal records consistent across operators.
Portbase’s Secure Chain adds digital authorisation to import container release and collection. Collection rights pass between authorised parties, including the relevant inland operator.
Physical seal checks complement this process by checking the seal itself. They do not establish collection rights and replace terminal security procedures.
What does ISO 17712 certification mean?
ISO 17712 sets requirements for mechanical freight container seals. ISO currently lists the 2013 edition as valid, following confirmation in 2023.
The standard distinguishes indicative, security and high security seals. When your customer or transport arrangement requires high security, confirm that the exact product meets the classification.
Ask for documentation covering the supplied model and variant, including applicable physical strength and tamper evidence testing and manufacturer security practices. A general claim that a supplier offers ‘ISO seals’ is insufficient for selecting a specific product.
A tamper evident seal helps reveal interference. It does not guarantee that cargo cannot be accessed, establish the contents of a container or replace wider security controls.
ISO certification and Dutch customs transit
Dutch customs recognises competent body ISO 17712:2013 certification as satisfying specified technical requirements for seals of a special type.
However, certification does not replace the relevant authorisation, seal approval or identification conditions. Businesses using these seals for customs transit should check their particular arrangement with their customs specialist.
For US bound shipments involving CTPAT requirements, also confirm the applicable participants criteria and your customer’s sealing instructions. Buying a seal does not make a business CTPAT certified.
Make seal checks part of every handover
A suitable seal needs a consistent operating procedure.
Check the container and closure points. Apply the specified seal according to its instructions, verify that is it secured and record the seal number against the shipment.
Compare the number with the shipment record. Inspect the seal and closure area for damage or signs of interference. Follow the products verification instructions and record the check.
Routine handovers should not involve removing the seal.
Check identity and condition before authorised removal. If an inspection requires replacement, record the original and replacement numbers, the reason and the authorised party involved.
For missing, damage of mismatched seals, follow your escalation procedure and obtain instructions before opening or moving the shipment further.
What to ask your seal supplier
Before comparing prices, establish a common specification:
- Application: container, trailer or another closure point.
- Classification: the security level required by your customer or procedure.
- Evidence: documentation matching the exact model and variant.
- Identification: readable, unique numbering and suitable recording options.
- Handling: installation method, verification instructions and removal tools.
- Supply: order quantities, delivery schedule and numbering continuity.
Confirm fit on the equipment you actually use. A bolt seal and a cable seal are not automatically interchangable.

Requirements depend on the customs procedure, customer, carrier and destination. Confirm what applies to your movement.
No. Confirm the classification and supporting evidence for the exact model and variant.
Yes, where the container remains closed and the applicable procedures allow it. Verify and record its identity and condition at the relevant handovers.
Treat it as a discrepancy. Follow your escalation procedure, record the details and obtain instructions before proceeding.
