How long does customs clearance take?

Clearance is usually fast and invisible. The courier files an entry electronically before the aircraft lands, the system processes it, and the parcel moves on. When that does not happen, the cause is generally identifiable rather than mysterious.

An incomplete or vague declaration is the most common cause. A customs declaration that says only "gift" or "sample" without a description, value, and country of origin cannot be classified, so it stops. The fix is information from the sender, which is why these delays feel slow — the courier has to go back up the chain.

An unpaid duty bill is the second. Since de minimis was suspended, far more parcels generate a charge, and many recipients do not realise a payment link is waiting. The shipment sits until it is paid, and most couriers return or abandon it after a holding period.

Other-agency requirements catch people by surprise. Food, supplements, cosmetics, medical devices, and certain electronics can require review by an agency other than CBP, each with its own paperwork. And finally, a shipment can simply be selected for examination, which adds days and sometimes an examination fee.

Declared value matters here in an underappreciated way. Under-declaring to reduce duty tends to trigger scrutiny rather than avoid it, and it exposes the importer to penalties well beyond the duty saved.
