Customs dwell depends on the lane, document status and actual process; do not make packaging or product decisions from a fixed-hour assumption.
Confirm before dispatch. With the importer, broker and carrier, verify process steps, required documents, contacts and whether a controlled holding location is available.
Monitor during the hold
Set logger access and alarm recipients. If data stops or an excursion appears, record the event time and each action, then notify quality.
Consider moving goods to another area or equipment only after the authorized process and suitable conditions are confirmed.
Release decision
Completion of customs formalities does not release a product from quality control. Quality should assess temperature history, product information and approved criteria.
Check current customs and document requirements with the competent customs source and broker.
Keep an event record. Keep shipment identity, entry and exit times, logger file, communications and decisions together.
Review the plan when the process, documents or holding location changes.
When uncertain, act on the verified process and quality assessment, not an assumed number of hours.
