Daily Brief: Why Are International Packages Held by Customs & How To Resolve It Rapidly?

The status "held by customs" for international shipments is not random inspection; customs authorities review goods in accordance with standardized regulatory procedures. Mastering key detention causes helps buyers avoid delays, unexpected charges and cargo seizure to ensure smooth clearance and delivery.

Missing or Inaccurate Documentation (Top Cause)

Missing core documents including commercial invoices and CN22/CN23 customs declarations, blank fields, vague commodity descriptions or incomplete recipient info will trigger detention for verification. Buyers shall verify shipping details before checkout and cooperate with reputable sellers proficient in international documentation.

Undervalued Shipment & Tax Evasion Alert

Sellers may deliberately understate declared value to evade import duties and VAT. Customs will detain shipments with obvious value discrepancies and request payment proof. Countermeasure: Require sellers to declare actual transaction value and submit order/invoice documents promptly once flagged.

Unpaid Import Duties & Taxes (DDU Scenario)

Every country sets a De Minimis tax threshold; shipments exceeding the limit are subject to duties and import VAT. Packages under DDU (Delivered Duty Unpaid) will be held until recipients settle all fees. Buyers shall check local tax thresholds in advance and follow courier payment notifications.

Prohibited & Restricted Goods

Customs classify goods into prohibited and restricted categories. Prohibited goods will be seized and destroyed. Restricted items such as food, plants, cosmetics and lithium batteries (dangerous goods) require special permits or health certificates. Verify import regulations before purchasing.

Counterfeit Goods & IP Infringement

Replica luxury goods and unlicensed branded products will be confiscated and destroyed by customs. In some jurisdictions, buyers may receive legal notices or fines from trademark owners, which is the most severe clearance detention scenario.

Standard Handling Steps for Detained Packages

1. Check tracking information to confirm pending payment or contact requirements; 2. Await official notifications via email or SMS from couriers; 3. Submit authentic and complete supporting documents timely. Delayed responses or forged invoices may lead to return or abandonment of cargo.
