US Customs Clearance for First-Time Importers: What Happens When Your Shipment Arrives

The Importer of Record (IOR) is the entity legally responsible for the imported goods — ensuring they comply with all US laws, paying duties and fees, and maintaining records for 5 years post-entry. The IOR is identified on the customs entry and is legally liable for any compliance violations.

For Taiwan brands shipping to Amazon FBA US, the IOR is typically either: your US entity (if you have one), your US-based freight forwarder acting as IOR on your behalf, or a third-party IOR service provider (companies that provide IOR-as-a-service for foreign sellers without a US entity). Not Amazon — Amazon is not the IOR for your FBA shipments, regardless of common misconception.

A US entity is not required to import goods into the US, but using a third-party IOR service adds cost and reduces direct control. If you plan to make regular US imports, establishing a US entity (LLC) provides cleaner IOR status and access to more financing options. Consult a US business formation attorney — costs are typically $500–2,000 for LLC setup.

Step 1 — Arrival: your shipment arrives at a US port of entry (e.g., Los Angeles, Long Beach, New York). CBP receives advance cargo information from the ocean carrier or airline.

Step 2 — Entry filing: your US customs broker files the customs entry with CBP using the ACE (Automated Commercial Environment) system. Entry type for commercial imports: Type 01 (Consumption Entry, formal entry for shipments valued over $2,500). For shipments under $2,500 from a single shipper, Type 86 (Section 321 informal entry) or postal entry may apply.

Step 3 — Duty assessment: CBP calculates import duties based on the HTS code, declared value (CIF — cost, insurance, and freight), and country of origin. Taiwan-origin goods pay the standard NTR (Normal Trade Relations) rate; check the specific HTS code for applicable duty rate.

Step 4 — Payment: duties and fees are paid by the customs broker on your behalf. The broker is reimbursed by you. Most brokers require either advance payment or a bond (continuous customs bond — approximately $500–800/year — covers all entries). A customs bond is required for all formal entries; your broker typically handles procurement.

Step 5 — Release: once duties are paid and CBP confirms compliance, the shipment is released. Release time ranges from same-day (automated clearance for low-risk shipments) to several weeks (if selected for physical examination).

CBP selects shipments for examination based on risk profiling, random selection, and specific intelligence. An estimated 3–5% of commercial shipments receive a physical examination, though rates vary significantly by origin, commodity, and importer history.

Exam types: Document Review (CBP reviews paperwork — no physical access to cargo; fastest). X-ray or NII scan (non-intrusive imaging at the port; minimal delay, typically 1–3 days). Intensive exam (physical inspection, container unloaded at a devanning facility; 3–10 day delay, cost typically $500–3,000 depending on container size and examination scope).

Examination costs (except document review) are borne by the importer. These costs are typically not recoverable — they are part of the risk of importing. Importers with CBP-approved Customs-Trade Partnership Against Terrorism (C-TPAT) certification receive reduced examination rates. C-TPAT certification requires supply chain security documentation and an application process, but is worthwhile for high-volume importers.

Section 301 scrutiny: while Taiwan-origin goods are not subject to Section 301 tariffs (unlike China-origin goods), CBP pays particular attention to country of origin claims, especially for goods with Chinese-manufactured components. If your product's Taiwan-origin status is questioned, be prepared to provide a Bill of Materials and manufacturing records demonstrating substantial transformation in Taiwan.

Cause 1 — Document errors: mismatch between commercial invoice, packing list, and bill of lading (quantity, description, HS code inconsistencies). Solution: have your freight forwarder review all documents for consistency before shipment, not at arrival.

Cause 2 — Incorrect or missing HS classification: CBP may reclassify your goods, triggering additional duty or admissibility review. Solution: obtain a binding ruling from CBP before your first shipment if you have any doubt about the correct HTS code. Binding rulings are free and legally binding — CBP cannot charge you a different duty rate if you comply with the ruling's conditions.

Cause 3 — Compliance holds (FDA, CPSC, EPA): products requiring agency clearance (food, supplements, cosmetics, children's products, electronics) may be placed on hold for the relevant agency's review. This can add 2–4 weeks to clearance. Solution: file required pre-market notifications (FDA Prior Notice for food, FDA registration for supplements, CPSC CPSIA testing for children's products) before shipment arrives.

Cause 4 — Pest interception by USDA-APHIS: wood packaging materials (pallets, crates) must comply with ISPM 15 phytosanitary treatment requirements (heat treatment or methyl bromide fumigation, marked with the IPPC symbol). Non-compliant wood packaging triggers immediate fumigation or return. Solution: specify ISPM 15-compliant packaging in your supplier contract and verify compliance documentation before shipment.
