Selling on Amazon or eBay opens doors to a global marketplace, but with great opportunity comes the challenge of customs clearance. Importing products from overseas into the United States requires understanding regulations, documentation, and duties to ensure your shipments arrive on time and are compliant with U.S. law. This guide will help sellers navigate the complexities of customs clearance, minimize delays, and save costs.
Every product shipped internationally must pass through U.S. Customs and Border Protection (CBP). Proper clearance ensures:
Compliance with federal laws and import regulations
Avoidance of costly delays, fines, or seizure of goods
Accurate calculation of import duties and taxes
Smooth delivery to Amazon fulfillment centers or your warehouse
Without understanding the customs process, online sellers risk stockouts, negative reviews, and financial penalties.
Import duties are taxes imposed on certain imported goods based on their Harmonized System (HS) code. Sellers should:
Determine the correct HS code for each product
Check the applicable duty rate on the CBP website or via a licensed customs broker
Include duties and taxes in your pricing strategy to maintain profitability
Failing to calculate duties correctly can lead to unexpected costs or shipment delays.
To clear customs successfully, ensure your shipment has the following:
Commercial Invoice: Details the seller, buyer, product description, quantity, and value.
Packing List: Breaks down each box, quantity, and contents for inspection.
Bill of Lading or Airway Bill: Proof of transport from origin to U.S. port.
Certificates or Licenses (if applicable): Some products, like electronics, cosmetics, or food require additional certification.
A licensed customs broker can help prepare and verify these documents to prevent compliance issues.
Amazon and eBay sellers typically use:
Express Couriers (DHL, FedEx, UPS): Fast clearance, ideal for small packages, but higher shipping costs.
Freight Forwarders (FCL/LCL shipping): Cost-effective for bulk shipments but requires more planning.
Each method affects customs clearance timelines and paperwork requirements.
Working with a licensed customs broker is highly recommended for online sellers. They provide:
Expertise in import regulations and HS codes
Assistance with duty classification and tariff calculations
Preparation and submission of all customs documentation
