Interactive explainer

From information to customs release

01 Describe
Identify what the goods are, who is trading and where they originate.
02 Document
Align invoice values, packing details and any required authorisations.
03 Review
The declarant submits information; customs may request evidence or inspection.
04 Release
After applicable checks and payments, arrange release and onward delivery.

Understand the scope

Build a landed-cost worksheet for the actual destination and shipment. Record tariff classification, origin, customs valuation basis and the applicable date. Ask the broker which valuation adjustments are required; the invoice total alone may not be the complete customs value. Check whether freight, insurance or other adjustments are already included before adding them again.

Prepare and verify

List customs duty, import VAT or GST, and any other applicable government charges separately. Add brokerage, carrier handling and storage as service costs. A duty exemption does not automatically waive consumption taxes, declarations or private service fees; check each charge independently. The tax base can differ from the customs-duty base under destination rules.

Complete the process

Obtain an itemized estimate showing currency, exchange-rate basis and assumptions. Confirm who pays and whether any tax recovery is available under local rules. Reconcile the estimate against the final assessment and invoices, and retain the evidence supporting declared values. Import tax that is recoverable under local rules can still affect cash flow initially.

Worked example

Two offers quote the same goods price, but one includes international freight and the other lists it separately. Before comparing landed costs, normalize the cost items and confirm their valuation treatment. Otherwise freight may be omitted or counted twice, and a seemingly cheaper offer can produce a misleading budget.

Common mistakes

Typical errors are assuming duty-free means cost-free, reusing an old exchange rate or counting freight twice. When records disagree, trace each field to its source instead of choosing the most convenient value. Correct the source and affected documents, identify the approved version, and tell the broker what changed before filing.

Next actions

Keep an estimate-versus-actual table and explain each material difference. Keep the decision, supporting evidence and responsible person's name together. Set a review trigger for changes in the product, supplier or destination, so the next shipment starts from checked information rather than an unquestioned copy of the last file.

Before you ship

Separate duties, taxes and service fees.
Confirm the valuation basis with the broker.
Reconcile estimates with actual assessed charges.
