Duty or tax is owed and nobody has paid it
Very commonThe single most common reason a parcel sits still. Customs has assessed a charge and the carrier is waiting for the recipient to pay before it releases the goods. The request often arrives by SMS or email and gets filtered as spam.
What fixes it: Check your tracking page, spam folder and any carrier SMS for a payment link. Pay through the carrier's official site — never a link in an unexpected text.
The customs declaration is vague or incomplete
Very common"Gift", "sample" or "goods" is not a description. Customs cannot classify what it cannot identify, so the parcel is parked until the sender supplies a proper description, value and HS code.
What fixes it: Ask the sender for a corrected commercial invoice with a specific description, unit value, quantity, country of origin and HS code.
Routine or targeted inspection
CommonA percentage of parcels is physically examined, some at random and some because the lane, sender or declared category is flagged. Nothing has gone wrong — the queue is simply slow.
What fixes it: Wait. Recipients cannot expedite an inspection, and calling daily does not move the queue.
Restricted or prohibited contents
CommonFood, supplements, seeds, batteries, cosmetics, medicines, plant and animal products, and anything with a lithium cell all have import rules that vary by country and are enforced at the border.
What fixes it: Check the destination authority's prohibited and restricted list. If the item is restricted, the parcel is usually returned or destroyed — arrange a refund with the seller.
Value or origin looks wrong
Less commonAn obviously under-declared value, or an origin that does not match the shipping lane, triggers a valuation query. Customs can substitute its own valuation and add a penalty.
What fixes it: Supply the order confirmation or payment receipt showing what you actually paid. Never ask a sender to under-declare — it is illegal and it makes the hold longer.
The importer needs a licence or registration
Less commonCommercial quantities, controlled goods and some regulated categories require the importer to hold a registration number or permit before release.
What fixes it: If you are importing commercially, register with the destination authority or appoint a customs broker to clear on your behalf.
