For many importers, customs clearance is a black box — cargo disappears into it, delays happen, and unexpected bills arrive. This guide demystifies the process, walking you through exactly what happens at each step.
Step 1: Arrival Notification
The process begins when the carrier notifies the consignee (or their freight forwarder) that the cargo has arrived. At this point, the clock starts — most countries have free time periods (typically 3-7 days at port) before storage charges begin accumulating.
Step 2: Document Submission
Your freight forwarder or customs broker submits a customs entry — a formal declaration to the customs authority — along with supporting documents: commercial invoice, packing list, bill of lading or air waybill, and any required licences or certificates.
Step 3: HS Code Classification and Duty Calculation
Customs classifies your goods using the Harmonised System code declared on the entry. This code determines the applicable duty rate. Duty is calculated as a percentage of the dutiable value (typically CIF basis in most countries).
Step 4: Risk Assessment and Examination
Customs uses risk-profiling algorithms to decide whether to examine the cargo physically or release it based on documents alone. Physical examinations can add 1-5 days to clearance time.
Step 5: Duty Payment
Once the customs entry is assessed, duties, taxes, and any other applicable levies must be paid before the cargo is released. Many importers set up deferred duty accounts with customs for monthly payment.
Step 6: Cargo Release
Once the customs authority issues a release order, your cargo can be collected from the port or airport. Your freight forwarder will coordinate this and arrange onward delivery.
How to Speed Up Customs Clearance
- Pre-file your customs entry before the vessel or aircraft arrives
- Ensure your commercial invoice is complete, accurate, and consistent with all other documents
- Use correct HS codes — misclassification is the most common cause of customs queries
- Apply for trusted trader or AEO status if you are a regular importer
