Home > Guides > Package held at customs
Customs holds packages for three main reasons: missing or unclear paperwork, inspection, or money owed. Vague descriptions like 'gift' or 'parts', a missing invoice, or a value that looks wrong will stall a parcel. If duties or taxes are due, the package waits until someone pays. Most holds clear once the carrier gets the right document or the fee is paid.
| Reason for the hold | What it looks like in tracking | What fixes it |
|---|---|---|
| Unclear customs declaration | "Held for documentation" or "information required" | Sender provides a specific description, value, and HS code |
| Physical inspection | "Under review" or "selected for examination" | Nothing: you wait, usually a few business days |
| Duties or taxes owed | "Payment required" or "awaiting payment" | Recipient pays the carrier, or self-clears at a customs office |
| Restricted or prohibited item | "Seized" or "returned to sender" | Often nothing: the item may be destroyed or sent back |
| Address or recipient problem | "Undeliverable" or "recipient unidentified" | Correct the address with the carrier |
The customs declaration is the parcel's passport, and officers read it skeptically. The most common stall is a vague description: "gift", "parts", "samples", or "merchandise" tells the officer nothing, so the parcel gets set aside until someone clarifies. A declared value that looks wrong (a "used laptop" valued at five dollars) triggers the same response. Commercial shipments need a proper invoice attached; missing it is an automatic hold. Here is the part shippers learn the hard way: the declaration has to match the contents, not the story. Marking a purchased item as a gift to dodge duty is misdeclaration, and if the parcel is opened, the sender can face penalties while the parcel sits.
Sometimes for a reason, sometimes for no reason at all. X-ray flags (dense objects, liquids, organic material), sniffer-dog alerts, and risk profiles (certain origin countries, certain declared contents) all earn a closer look. But a meaningful share of inspections are random: officers pull parcels off the line to keep smugglers guessing, and your parcel can be the unlucky one. Random inspections usually clear in a few business days, though backlogs after holidays or during strikes can stretch that. One non-obvious detail: repackaging after an inspection is not always careful, so photograph valuable items before shipping in case you need to file a damage claim later.
It means the parcel's value exceeded the duty-free threshold, or the item type carries duty regardless of value (alcohol, tobacco, and some textiles are classic examples). The parcel is not moving until someone pays: the government does not release goods on a promise. With couriers, the company usually advances the payment and bills you, plus a brokerage fee for doing the paperwork. With postal shipments into Canada, Canada Post collects at delivery or at the post office counter. Until the money changes hands, the parcel sits in a bonded warehouse, and after a grace period, storage fees can start accumulating daily.
Start with the tracking page: it usually names the hold reason, and the carrier's customer service can see more detail than the public tracking shows. If it is paperwork, contact the sender: only they can amend the declaration or supply the missing invoice. If it is money owed, pay the carrier or look into self-clearing at a customs office, which skips the broker fee. If it is an inspection, there is genuinely nothing to do but wait; calling daily does not speed it up. And if the tracking says the item is prohibited, accept the outcome early: seized parcels are rarely released, and arguing with a border officer's classification is a losing battle.
Mostly, yes. Shippers should write specific descriptions ("men's cotton t-shirt", not "clothes"), declare honest values, attach commercial invoices for business shipments, and check the destination country's prohibited list before packing. Recipients ordering from abroad should expect that anything over the duty-free threshold will cost extra and take longer. And both sides should build in buffer time: a parcel that must arrive by a date should ship at least two weeks early across a border, because a single inspection can eat a week without anyone doing anything wrong.
