Start with the movement type

Before documents are reviewed, identify whether the goods are being imported, exported, re-exported, transhipped, temporarily moved or returned after repair. The movement type affects the permit pathway, the parties involved and the supporting information that may be required.

State the origin, destination, transport mode, cargo-ready date and operational deadline. A clear movement brief helps the declarant distinguish a routine filing from a shipment that needs licensing, origin, valuation or checkpoint clarification.

Prepare consistent commercial data

The commercial invoice, packing list and transport document should describe the same transaction. Check names, addresses, quantities, package counts, weights, currency, values and goods descriptions before submission. Generic descriptions such as parts, samples or accessories often require more detail.

  • Importer, exporter, consignee and consignor details
  • Specific goods description and HS code where known
  • Quantity, gross weight, net weight and package count
  • Invoice value, currency, freight and insurance information
  • Licence, certificate or authority approval where applicable

Confirm ownership and escalation

Assign one person who can approve corrections, answer product questions and authorise additional charges. When deadlines are tight, unclear ownership is often a larger cause of delay than the permit submission itself.

IMPORT.SG can coordinate the declaration workflow within an agreed scope, but permit outcomes remain dependent on accurate information, complete documents and authority requirements.
