While you can't eliminate the chance of a customs hold entirely, several practical steps significantly reduce the likelihood — and most of them come down to accurate paperwork and prompt payment rather than anything complicated.
Choose couriers that handle their own customs brokerage (DHL, FedEx, UPS, Aramex) over postal-network shipping when speed matters, since brokered shipments tend to pre-clear much faster. If you're the sender, ensure the customs declaration includes an accurate, specific item description ("men's cotton t-shirt," not just "clothing") and a realistic declared value — vague descriptions and undervalued declarations are two of the most common triggers for manual customs review.
If you're ordering internationally, check whether the platform (Amazon, eBay's Global Shipping Program, Temu, Shein) collects import duties at checkout — pre-paid duty shipments generally clear faster since there's no payment step waiting on the receiving end.
Keep an eye on tracking for any customs-hold notifications and respond to duty payment requests as quickly as possible — this single step prevents the majority of extended holds. If you receive a request for additional documentation (invoice, proof of purchase), respond through the specific channel the courier provides rather than a general inquiry, since this routes faster to the right department.
For restricted or regulated categories (certain electronics, supplements, branded goods in bulk quantities), check your destination country's import rules in advance — these categories are far more likely to trigger an extended hold regardless of how well the rest of the paperwork is handled.
