Calculate customs duties on imported goods based on customs value and duty rate. Estimate import duty costs for US, EU, and international trade.
Customs duties are taxes imposed by governments on goods imported across international borders. The duty amount is typically calculated as a percentage of the customs value — usually the transaction value (price paid or payable) plus freight and insurance costs to the port of entry. Duty rates vary by product category, classified using the Harmonized System (HS) code.
In the United States, customs duties are collected by U.S. Customs and Border Protection (CBP) and range from 0% (duty-free goods) to over 25% for certain products. The duty rate depends on the HS code classification, the country of origin, and any applicable trade agreements or special tariff programs.
This calculator estimates customs duty based on the declared customs value and applicable duty rate. Use it for import cost planning, landed cost analysis, and budgeting for international sourcing.
Supply-chain managers, warehouse operators, and shipping coordinators rely on precise customs duty data to maintain efficiency and control costs across complex distribution networks. Revisit this calculator whenever conditions change to keep your logistics plans aligned with real-world performance.
Customs duties directly impact the landed cost of imported goods and can make or break the economics of international sourcing. Accurately calculating duties before placing orders helps you compare domestic vs international suppliers, price imported products correctly, and avoid cash flow surprises at the port. Real-time recalculation lets you model different scenarios quickly, ensuring your logistics decisions are backed by accurate, up-to-date numbers.
Customs Duty = Customs Value × Duty Rate % MPF = Customs Value × 0.3464% (min $31.67, max $614.35) HMF = Customs Value × 0.125% (ocean only) Total Duties & Fees = Duty + MPF + HMF
Result: Total Duties & Fees = $2,735.70
Duty = $50,000 × 5% = $2,500. MPF = $50,000 × 0.3464% = $173.20. HMF = $50,000 × 0.125% = $62.50. Total = $2,500 + $173.20 + $62.50 = $2,735.70.
Customs valuation determines the price on which duties are calculated. The WTO Customs Valuation Agreement establishes six methods, with transaction value (actual price paid) as the preferred method. Adjustments may apply for royalties, assists, buying commissions, and post-importation payments.
Customs duties are one component of landed cost, which also includes freight, insurance, brokerage fees, storage, and inland transportation. A complete landed cost analysis compares the all-in cost of importing against domestic sourcing alternatives. Duties can represent 5-25% of landed cost depending on the product.
Free trade agreements (FTAs) like USMCA (North America), CAFTA-DR (Central America), and bilateral agreements with countries like Korea, Australia, and Chile can reduce or eliminate duties. To qualify, goods must meet rules of origin requirements and be accompanied by a valid certificate of origin.
Customs value is the value declared for duty assessment purposes. In the US, it's typically the transaction value — the price actually paid or payable for the goods when sold for export. It may include or exclude freight and insurance depending on the country's valuation method (FOB vs CIF).
Duty rates are published in the Harmonized Tariff Schedule (HTS). In the US, look up your product's HS code in the USITC HTS database (hts.usitc.gov). Each classification has a duty rate that applies based on the country of origin.
The MPF is a fee charged by CBP for processing formal import entries. It's currently 0.3464% of the customs value, with a minimum of $31.67 and a maximum of $614.35 per entry. Informal entries (under $2,500) have different fee structures.
The HMF is a 0.125% ad valorem fee on the value of cargo imported via ocean transportation. It funds harbor maintenance and improvement projects. It does not apply to air freight or overland imports from Canada/Mexico.
Duties can be legally reduced through trade agreements (FTAs), duty drawback programs, Foreign Trade Zones, temporary importation bonds, and proper product classification. Duty avoidance through misclassification or undervaluation is illegal.
Section 301 tariffs are additional duties (currently 7.5-25%+) imposed on certain goods imported from China. These are applied on top of normal customs duties and affect thousands of product categories. Check the USTR exclusion list for exemptions.
