Understanding import customs and duties is essential before you ship a single box of Korean products to an Amazon fulfillment center in the United States. Customs clearance, tariff classification, and import documentation determine how much you pay, how fast your goods arrive, and whether your inventory reaches Amazon without costly holds. This guide explains the key concepts Korean sellers need to move products from Korea into the US Amazon FBA network smoothly and legally.
Who Is the Importer of Record?
Every shipment entering the US needs an Importer of Record (IOR), the party legally responsible for ensuring the goods comply with US law and that duties are paid. Amazon does not act as the importer of record for your FBA inventory, so you cannot simply ship boxes to a fulfillment center and list Amazon as the consignee. Many Korean sellers set up a US entity or use a customs broker arrangement to serve as the importer of record. Getting this right matters because the IOR is accountable to US Customs and Border Protection (CBP) for accurate declarations and payment.
HS Codes and Tariff Classification
Every product is classified under a Harmonized System (HS) code, which determines the duty rate. Misclassifying your goods can lead to overpayment, underpayment, penalties, or clearance delays. Before importing, identify the correct classification for each product, because a small difference in category can change the duty rate substantially. A licensed customs broker can help you classify accurately, and it is worth confirming the code before your first large shipment rather than guessing. The declared value, which is generally the transaction value of the goods, also affects how duties are calculated.
The KORUS Free Trade Agreement
Korea and the United States have a free trade agreement (KORUS FTA) that can reduce or eliminate duties on many qualifying Korean-origin products. To claim preferential treatment, your goods must meet the agreement’s rules of origin, and you must be able to support the claim with proper documentation, such as an origin declaration. Not every product qualifies, and simply shipping from Korea does not automatically mean the goods are Korean-origin under the rules. Verifying eligibility can meaningfully lower your landed cost, so it is worth checking each product against the FTA criteria with a knowledgeable broker.
Import Customs and Duties: Fees to Expect
Beyond the basic duty rate, imports may incur other charges. A Merchandise Processing Fee and, for ocean shipments, a Harbor Maintenance Fee typically apply. Some products face additional duties or regulatory requirements from agencies such as the FDA (for food, cosmetics, and supplements) or the FCC (for electronics). Because these fees and rules vary by product, build them into your cost calculations early. Fees and rates change over time, so treat any figure as approximate and confirm current rates before importing. The total landed cost, which includes product cost, freight, duties, fees, and FBA prep, is what you must beat with your selling price to stay profitable.
De Minimis and Shipment Value
The US has historically applied a de minimis threshold allowing low-value shipments to enter with simplified treatment, but relying on splitting inventory into many small parcels to avoid duties is risky and rules in this area have been changing. For commercial FBA restocking, most sellers ship in bulk and clear the goods formally through a broker. Plan your logistics around formal entry for commercial quantities rather than depending on informal thresholds, and keep up to date because policy in this area evolves.
Preparing Inventory for Amazon FBA
Customs clearance is only half the journey. Amazon has strict FBA prep and labeling requirements, including product barcodes, shipment labels, poly-bag and suffocation warnings, and packaging standards. Goods that clear customs but fail FBA prep can be refused or charged extra fees at the fulfillment center. Many Korean sellers use a US-based prep center or third-party logistics provider that receives the imported goods, inspects and labels them to Amazon’s specifications, and forwards them to fulfillment centers. This extra step protects you from FBA rejections and keeps your inventory flowing.
Working With a Customs Broker and Freight Forwarder
For most sellers, the practical solution is to partner with a licensed customs broker and a reliable freight forwarder. The forwarder arranges shipping from Korea, and the broker handles the customs entry, classification, duty payment, and FTA claims on your behalf. Provide them with accurate commercial invoices, packing lists, and product details, and keep records of every shipment. Clear documentation and experienced partners are the difference between smooth, predictable imports and unexpected holds that can leave you out of stock during a critical sales period. Build a buffer into your restocking timeline to account for ocean transit, customs clearance, and FBA check-in, all of which can take longer than expected, so that a delay at any single step does not translate into lost sales while your listing sits without inventory.
Frequently Asked Questions
Can Amazon be the importer of record for my FBA shipment?
No. Amazon does not act as importer of record for seller inventory. You must designate yourself or a qualified party, often through a US entity and a customs broker, to be legally responsible for the import and duty payment.
Does the KORUS FTA eliminate all duties on Korean products?
Not automatically. The agreement reduces or removes duties on many qualifying goods, but products must meet rules of origin and be properly documented. Some items do not qualify, so verify each product’s eligibility before claiming preferential treatment.
What happens if I classify my product under the wrong HS code?
Incorrect classification can cause you to overpay or underpay duties and may trigger penalties or clearance delays. Confirming the correct code with a licensed customs broker before your first shipment reduces risk and helps you budget landed costs accurately.
