Determines duty rates, statistical reporting, and regulatory requirements. ### HTS Code Structure 10-digit code: first 6 digits are international (HS), next 4 are US-specific. More specific codes have more precise duty rates. ### Classification Determination Importers must exercise reasonable care in classifying goods. Incorrect classification can result in duty underpayment and penalties. ### Binding Rulings CBP can provide binding classification rulings upon request, providing certainty on HTS classification for specific products. ## Customs clearance process 01 Determine HTS classification Classify your product using the Harmonized Tariff Schedule to determine duty rate and any special requirements. 02 Prepare import documentation Gather commercial invoice, bill of lading, packing list, and any required certificates or permits. 03 File entry with CBP Submit CBP Form 7501 through a customs broker or directly if you have importer status. Pay estimated duties. 04 Customs examination CBP may examine shipment to verify documentation and compliance. Most shipments clear without physical examination. 05 Duty payment and release Pay any additional duties assessed. Goods are released once all requirements are satisfied. 06 Record retention Maintain all import documentation for 5 years from date of entry as required by CBP. ## Common compliance mistakes Incorrect HTS classification - leads to wrong duty payment and potential penalties Incomplete commercial invoice - missing required information causes delays Inconsistent documentation - invoice, bill of lading, and packing list must match Not identifying required permits - some products need additional approvals before import Missing country of origin markings - products must be marked with country of origin Not maintaining records for 5 years - CBP can request documentation years after import ## Frequently asked questions ### Do I need a customs broker to import into the US? You can import directly if you obtain an importer number from CBP and understand customs requirements. However, most importers use customs brokers because customs procedures are complex and errors can be costly. Brokers handle classification, documentation, and communication with CBP. ### How do I determine the correct HTS code for my product? Start by searching the HTS using product keywords and descriptions. Review the descriptions and notes carefully. If uncertain, you can request a binding ruling from CBP for certainty. Classification requires careful analysis of the product's characteristics, composition, and intended use. ### What are Incoterms and why do they matter? Incoterms are standardized trade terms that define responsibilities between buyer and seller for delivery, risk transfer, and costs. They affect customs valuation because duties are calculated based on the transaction value at the US border. Different Incoterms (FOB, CIF, DDP, etc.) change what's included in the dutiable value. ### How long does customs clearance typically take? Most shipments clear customs within 1-2 days if documentation is complete and accurate. Shipments selected for examination may take 3-5 days or longer. Complex shipments requiring additional permits or documentation can take weeks. Proper preparation minimizes delays. ### What are the penalties for customs violations? CBP can impose penalties for various violations including negligence, gross negligence, and fraud. Penalties can range from the value of the merchandise to multiple times the duty loss. Criminal penalties may apply for intentional violations. Importers must exercise reasonable care in compliance. **Disclaimer:** This guide provides general information about US import documentation.
