How to Use the US Import Tariff Calculator
Importing goods into the United States in 2026 is more complex than ever. With the Trump administration's trade policies creating new tariff structures — including the 10% global baseline tariff, country-specific reciprocal rates, and aggressive Section 232 national security tariffs — importers need accurate, real-time landed cost calculations to protect their profit margins. This calculator gives you an instant, itemized breakdown of every fee your shipment will incur at the US border.
To use it, start by entering the Product Value — this is the price you paid for the goods, also known as the transaction value. Add your Shipping Cost (freight charges to the US port of entry) and Insurance Cost (cargo insurance premium). Then select the Country of Origin and Product Category — these two factors determine your base tariff rate and any additional Section 232 surcharges. The calculator instantly computes your Customs Value, Import Duty, Merchandise Processing Fee (MPF), Harbor Maintenance Fee (HMF), and your total Landed Cost.
This tool is essential for e-commerce importers calculating Amazon FBA landed costs, small businesses sourcing products internationally, customs brokers providing client estimates, and eBay or Shopify sellers evaluating whether imported products will be profitable after all duties and fees.
Detailed Tariff & Fee Formula Breakdown
Base Tariff Rates by Country (2026)
The base tariff rate varies dramatically by country of origin, reflecting the current administration's trade policy priorities. China faces the highest base rate at 20% — a combination of Section 301 tariffs from the first Trump term, the 10% global baseline tariff implemented in April 2025, and reciprocal China-specific rates. Vietnam and Other countries face 10% base rates. The UK and EU face lower 3.5% rates reflecting negotiated trade relationships. India falls in the middle at 5.5%. Canada and Mexico are at 0%under the USMCA agreement — but only for goods that meet USMCA rules of origin. Non-USMCA-compliant goods from Canada or Mexico face the "Other" rate of 10%.
Section 232 National Security Surcharges
In addition to base tariffs, the US applies Section 232 "national security" tariffs on specific product categories. Steel and aluminum products face a staggering +50% surcharge on top of the base tariff rate. Automotive parts (including finished vehicles and key components) face a +25% surcharge. Pharmaceuticals currently have a 0% surcharge, but this is scheduled to increase to 100% effective July 31, 2026 — a massive change that will reshape the pharmaceutical supply chain. Electronics, apparel, and general goods currently have no Section 232 surcharge. The formula is: Duty Rate = Base Tariff Rate + Section 232 Surcharge Rate. So Chinese steel faces 20% + 50% = 70% total duty rate.
Merchandise Processing Fee (MPF)
The MPF is a customs user fee applied to all formal entries into the US. The rate is 0.3464% of the customs value (product value + shipping + insurance), with a minimum of $31.67 and a maximum of $614.35 per entry. For a shipment with a customs value of $10,000: MPF = $10,000 × 0.003464 = $34.64 (above the $31.67 minimum, so the full calculated amount applies). For a $5,000 shipment: MPF = $5,000 × 0.003464 = $17.32 — but the minimum of $31.67 applies, so you pay $31.67. For a $200,000 shipment: MPF = $200,000 × 0.003464 = $692.80 — but the maximum of $614.35 applies, capping the fee.
Harbor Maintenance Fee (HMF)
The HMF is assessed on most commercial cargo shipments arriving at US ports by vessel. The rate is 0.125% of the customs value, applied to the value of the cargo. There is no minimum or maximum HMF. For a $10,000 shipment: HMF = $10,000 × 0.00125 = $12.50. This fee funds the maintenance and operation of US harbors and ports, including dredging and infrastructure improvements. Note that HMF only applies to ocean freight shipments — air freight entries are not subject to HMF, though they still incur MPF.
Total Landed Cost Calculation
Your Total Landed Cost is the true cost of getting your product from the factory to your warehouse. The formula: Landed Cost = Product Value + Shipping + Insurance + Import Duty + MPF + HMF. This is the number that matters for your pricing, profit margins, and break-even analysis. If your product costs $10,000 FOB China, with $1,200 shipping, $150 insurance, at 20% tariff, your landed cost is $10,000 + $1,200 + $150 + $2,270 + $39.34 + $14.19 = $13,673.53. Your effective duty rate on the product value alone is 22.7% — but on the full landed cost it is 16.6%. This distinction is critical for accurate pricing.
Frequently Asked Questions (FAQs)
What is the current US tariff rate from China in 2026?
The current effective base tariff rate on Chinese imports in 2026 is 20%. This includes the original Section 301 tariffs (typically 7.5–25% depending on the product list), the 10% global baseline tariff implemented in April 2025, and additional reciprocal China-specific tariffs imposed in 2025. However, the rate is scheduled to increase dramatically to 44%+ on November 10, 2026, under the reciprocal tariff framework. This will make Chinese imports significantly more expensive — a product that costs $10,000 today would incur $4,400+ in duties after the increase, versus $2,000 today. Importers should front-load orders before the deadline and explore alternative sourcing from Vietnam, India, or USMCA countries.
Are Canada and Mexico exempt from US tariffs in 2026?
Yes — goods that qualify under the USMCA (United States-Mexico-Canada Agreement) rules of origin are subject to 0% base tariff. To qualify, goods must contain a sufficient percentage of North American content (typically 60–75% depending on the product category) and meet specific production requirements. However, goods that do notqualify for USMCA treatment face the "Other" rate of 10%. Additionally, there have been temporary tariff actions on Canadian and Mexican goods in 2025–2026 related to fentanyl trafficking and immigration enforcement — these are separate from the trade tariff structure. Always verify your product's USMCA eligibility with a customs broker before assuming duty-free entry.
What is the Section 232 tariff and who does it affect?
Section 232 of the Trade Expansion Act of 1962 allows the US President to impose tariffs on imports that threaten national security. In 2026, these tariffs primarily affect steel and aluminum (additional 50% surcharge) and automotive parts and finished vehicles (additional 25% surcharge). The scope of Section 232 has expanded significantly under the current administration. For example, a Chinese steel product faces a combined rate of 70% (20% base + 50% Section 232). An EU auto part faces 28.5% (3.5% base + 25% Section 232). Pharmaceuticals are exempt for now but will face a 100% Section 232 surcharge starting July 31, 2026. Importers in these categories must factor these surcharges into their cost models or the business becomes unviable.
What are MPF and HMF fees?
MPF (Merchandise Processing Fee) is a customs user fee of 0.3464% of the customs value, with a minimum of $31.67 and a maximum of $614.35 per formal entry. It covers the cost of CBP (Customs and Border Protection) processing your import paperwork. HMF (Harbor Maintenance Fee) is 0.125% of the customs value for ocean freight shipments. It funds US harbor maintenance, dredging, and port infrastructure. HMF only applies to cargo arriving by vessel — air freight and truck shipments are exempt. Both fees are non-negotiable and apply to most commercial import shipments regardless of tariff rates. Together, they add approximately 0.47% to your effective duty rate on ocean shipments.
How do I calculate landed cost for Amazon FBA?
Amazon FBA sellers importing from China need to calculate their total landed cost to ensure profitability. Start with the product cost (FOB price from your supplier), add shipping (ocean freight or air freight to a US port), import duties (20% from China), MPF ($31.67 minimum or 0.3464%), HMF (0.125% for ocean freight), customs broker fees (typically $100–$200 per entry), drayage (trucking from port to warehouse, $200–$500), Amazon FBA inbound placement fees, and the FBA storage and fulfillment fees. A $10 product purchased from China at $8 FOB can easily have a total landed cost of $12–$15 by the time it reaches an Amazon fulfillment center — that 50–87% markup over the purchase price must be accounted for in your pricing strategy. Use our E-Commerce Profit Margin Calculator to model the full impact.
Will China tariff rates change after November 2026?
Yes — China tariff rates are scheduled to increase to 44%+ on November 10, 2026 under the reciprocal tariff framework. This is a phased increase from the current 20% base rate. The exact rate may vary by product category based on ongoing trade negotiations and legal challenges. After November 10, a $10,000 shipment from China would incur approximately $4,400+ in duties alone, compared to $2,000 today. This is a 120% increase in tariff costs. Importers who rely heavily on Chinese manufacturing should immediately begin: (1) diversifying suppliers to Vietnam, India, Mexico, or Turkey, (2) building inventory ahead of the deadline, (3) negotiating a supplier-funded tariff sharing arrangement, and (4) evaluating whether price increases can sustain their margins. After the increase, importing from Vietnam (10%), India (5.5%), or Mexico (0% under USMCA) will be significantly more attractive than China for most products.
How do tariffs affect eBay and Shopify sellers?
Tariffs directly impact the cost of goods sold for any seller importing products. An eBay or Shopify seller importing a widget from China at $10 with $2 shipping faces a current landed cost of approximately $15.20 after the 20% tariff. After November 2026, that same widget would cost approximately $17.70 landed — a 16% increase in cost. This forces sellers to either raise prices (risking lower conversion rates), reduce profit margins (risking business viability), or find alternative sourcing. The impact is most severe for sellers in competitive categories where price increases are difficult to pass on.

What products are completely exempt from US tariffs?
Certain categories of imports are exempt from US tariffs under various trade programs and legal frameworks. Goods imported from USMCA-qualifying Canadian and Mexican sources are exempt from base tariffs. Products imported under the Generalized System of Preferences (GSP) from designated beneficiary countries may qualify for duty-free entry, though China is not a GSP beneficiary. Section 321 de minimis shipments (value under $800) enter the US duty-free — this is why many direct-to-consumer e-commerce imports from China use this exemption, though there is ongoing discussion about lowering the de minimis threshold. Personal effects and household goods imported as part of a relocation are generally exempt. Returned US goods (goods manufactured in the US and returned without being advanced in value abroad) enter duty-free. Diplomatic shipments and shipments to certain government agencies may also be exempt. For commercial shipments over $800, however, very few exemptions apply, and most commercial goods from non-preferred trading partners face at least the 10% baseline tariff.
