π¦ Tariff Cost Calculator
What import duties add to your landed cost.
Total landed cost
Estimates for planning only, not financial advice.
Import $50,000 of goods at a 25 percent tariff with $3,000 freight, and you owe $12,500 in duty at the border. Landed cost: $65,500, or $65.50 per unit on a 1,000-unit shipment. The tariff is paid by you, the US importer, not by the foreign seller.
How to Use This Calculator
Enter the customs value of the shipment (usually the price you paid the supplier), the tariff rate for your product's HTS code and country of origin, freight and insurance, and the unit count. The calculator shows duty, landed cost, and per-unit impact.
Enter shipment value. Duty is assessed on the transaction value, generally what you paid the supplier.
Enter the tariff rate. Find your exact rate by HTS code; the examples below are illustrations, not your rate.
Read the per-unit duty. That is the number to build into your pricing.
The Formula
US tariffs are ad valorem, a percentage of value, collected by Customs when goods enter. Multiple tariffs stack additively on the same value: a 25 percent Section 301 duty plus a 10 percent reciprocal tariff means 35 percent total. Rates change by executive order and trade action, so verify the current rate for your HTS code before quoting customers.
Worked Example
$50,000 shipment, 25 percent rate, $3,000 freight, 1,000 units. Duty: 50,000 x 0.25 = $12,500. Landed: 50,000 + 12,500 + 3,000 = $65,500. Per unit: $65.50 landed, of which $12.50 is duty. If your pre-tariff unit economics were $53 cost against a $79 retail price, the duty just ate $12.50 of margin: you raise prices, absorb it, or re-source.
Recent Tariff Picture (Illustrative)
| Measure | Illustrative rate |
|---|---|
| IEEPA reciprocal tariffs (2025) | 10% baseline, higher per country |
| Section 301 on China (2018-) | 7.5% - 25% by product |
| Section 232 steel/aluminum | 25% (varied by period) |
| Average US statutory rate, 2025 peak | ~24.8%, vs 2.6% pre-2025 |
These move constantly: the Supreme Court struck down the IEEPA tariffs in February 2026, the administration replaced them with other authorities, and country-specific deals change rates monthly. Treat any published rate as a snapshot. Your customs broker's HTS lookup is the source of truth, not a headline.
Who Really Pays
Legally, the importer pays at the border. Economically, the cost splits three ways: importers absorb margin, foreign suppliers cut prices to stay competitive, and US consumers pay higher retail prices. Research on the 2018-2019 tariffs found US importers and consumers bore nearly the full cost. For your pricing decision, assume you bear it until you prove otherwise: model the per-unit duty in your margin stack and decide explicitly how much to pass through versus absorb.
Mitigation Playbook
Five levers, in order of practicality: reclassify under a lower-duty HTS code (with counsel, not creativity), shift sourcing to lower-tariff countries, use foreign trade zones to defer or reduce duty, apply for product exclusions where processes exist, and redesign products to change classification. Each has compliance risk; tariff engineering without legal review is how companies earn penalties. For the demand side of the same shock, our inflation calculator frames what pass-through means for consumers.
Legal Ways to Lower the Duty Bill
Five compliant levers exist, in rough order of practicality. First, classification review: have counsel verify the HTS code, since a surprising share of importers overpay on misclassified goods, and the fix is a ruling request, not a gamble. Second, country diversification: shifting sourcing to lower-duty origins, the friend-shoring wave in action. Third, foreign trade zones: admit goods into a US FTZ and duty is deferred until they enter US commerce, or eliminated if re-exported.
Fourth, duty drawback: reclaim up to 99 percent of duties paid on goods that are subsequently exported or destroyed, a paperwork-heavy but real refund program. Fifth, first-sale valuation: when buying through a middleman, duty can be based on the factory price rather than the middleman's markup if the transaction chain qualifies. Each lever needs customs counsel; the penalties for getting creative without it (fines, seized goods, import bans) dwarf the savings.
Tariffs Are a Cost to Manage, Not Just a Headline
Importers have legal tools to reduce duty bills: tariff engineering (classifying goods under lower-duty HTS codes where the product genuinely fits), first-sale valuation (duty on the factory price rather than the middleman markup), duty drawback (refunds on re-exported goods), and foreign trade zones (deferring duty until goods enter US commerce). Each requires documentation and expertise, but for high-volume importers the savings dwarf the compliance cost.
Longer term, supply-chain diversification is the strategic response: shifting sourcing across countries changes the applicable duty rates entirely. Model the landed cost per origin country with this calculator's logic, including freight and compliance, before moving production. Tariff policy changes with administrations; a supply chain built for one regime breaks in the next. Build flexibility, document everything, and treat duty minimization as an ongoing discipline rather than a one-time project.

Frequently Asked Questions
How do I calculate tariff cost?
Multiply the shipment's customs value by the tariff rate, then add freight and insurance for landed cost. A $50,000 shipment at 25% owes $12,500 in duty. Divide by units for the per-unit impact to build into pricing. Get the rate from your HTS code and origin country: the same product can face 0% from one country and 25% from another.
Who pays US tariffs?
The US importer, legally, at the border when goods clear Customs. Economically the burden splits among importers (margin), foreign suppliers (price cuts), and consumers (higher prices). Studies of recent tariffs found Americans bore most of the cost. The 'foreigners pay' framing is politically popular and economically backwards: the check is written in dollars at a US port.
What is the current US tariff rate on China?
It changes frequently across stacked measures (Section 301, reciprocal, fentanyl-related). Recent history ranged from 10% to over 100% on various tranches at various times. Check the current HTS-specific rate with a customs broker; headlines are not reliable for your product.
Do tariffs stack?
Yes, additively on the same customs value. A 25% Section 301 duty plus a 10% reciprocal tariff equals 35% total duty on the shipment value. Always total every applicable measure for your HTS code and origin country. Missing one stacked measure is the most common and expensive error in landed-cost math.
What is landed cost?
The full cost of getting goods to your door: product value + duty + freight + insurance (+ handling). It is the true unit cost for pricing decisions. Businesses that price off product cost alone and forget duty systematically underprice.
Can small businesses get tariff relief?
Sometimes: product-specific exclusion processes have existed for Section 301 duties, duty drawback refunds duties on re-exported goods, and foreign trade zones defer or eliminate duty on re-exports. Each has paperwork and timelines; a customs broker earns their fee here. Drawback alone can recover up to 99 percent of duties on re-exported goods, real money for distributors.
Do tariffs apply to samples and gifts?
Generally yes if they exceed de minimis thresholds. The US $800 de minimis for informal entry has been narrowed for some tariff measures, so even small shipments can face duties now. Check current rules before assuming samples slide through. E-commerce sellers shipping direct to US consumers have been caught by this change mid-strategy.
How do tariffs affect consumer prices?
Importers pass a large share through to retail over months. Research suggests most of recent tariff costs reached consumer prices. Expect 6-18 month lags as old inventory clears and contracts reset. The lag means tariff headlines today become price tags next year; businesses that reprice early protect margins while competitors absorb the hit.
What is an HTS code?
The Harmonized Tariff Schedule code classifying your product for duty purposes (10 digits in the US). The code plus country of origin determines your exact rate. Misclassification, accidental or otherwise, draws penalties; get it right with professional help. A surprising share of importers overpay on wrong codes: a classification review by counsel is often the highest-ROI hour in trade compliance.
Should I raise prices because of tariffs?
Model it first: compute per-unit duty with this calculator, then decide the split between pass-through, margin absorption, and cost mitigation. Blanket price hikes can cost more in lost volume than the duty; targeted ones on tariff-hit SKUs usually work better.
