What Customs Clearance Actually Involves

When your package crosses an international border, it must be presented to the destination country's customs authority for review. The customs agency determines:

For most commercial shipments moving through established carriers (DHL, FedEx, UPS), clearance happens quickly — often within hours. Problems arise when documentation is incorrect, items are on restricted lists, or customs officers choose to examine the goods physically.

What Customs Brokers Do and What They Cost

A customs broker is a licensed professional who files import documentation on your behalf, pays duties, communicates with customs officers, and ensures compliance. Their fees vary by market and complexity:

For express small parcel shipments, DHL/FedEx/UPS typically handle customs brokerage automatically (for a fee, often 2–3% of shipment value). For larger freight shipments, you'll engage your own broker.

Documentation That Must Be Correct

The most common cause of customs delays is incorrect or inconsistent documentation. Key documents and what they must show:

Commercial Invoice

The commercial invoice and packing list must agree exactly. If the invoice says 100 units and the packing list says 98, customs will flag it for physical examination.
