#1 Free US Import Tariff Calculator 2026 — Calculate Duties Instantly
Calculate US import duties, Section 301 tariffs, and total landed cost for any product in seconds. Free AI-powered tariff calculator updated for 2026 rates.
Calculating US import duties in 2026 is more complex than ever. With stacking tariffs from Section 301 (China), Section 232 (steel and aluminum), Section 122 (universal surcharge expiring July 2026), plus standard MFN rates, MPF, and HMF — a $10,000 shipment from China can carry $4,000–$7,000 in total duties depending on the product category. TariffCheck is the only free tool that calculates all of these layers simultaneously.
What Is a Tariff Calculator?
A US tariff calculator estimates the import duties, fees, and total landed cost for goods entering the United States. It uses the HTS (Harmonized Tariff Schedule) code — a 10-digit product classification number — to look up the applicable duty rate, then adds any special tariffs and fees.
In 2026, a complete tariff calculation includes:
| Tariff Layer | Applies To | Rate Range |
|---|---|---|
| MFN (Base) Duty | All countries | 0%–37.5% |
| Section 301 | China only | 7.5%–100% |
| Section 232 | Steel, aluminum, autos (all countries) | 25% |
| Section 122 | Most imports (expires Jul 24, 2026) | 10% |
| MPF | All formal entries | 0.3464% (min $31.67, max $614.35) |
| HMF | Ocean shipments | 0.125% |
Most tariff calculators online only show the MFN rate. TariffCheck calculates all six layers.
How to Use TariffCheck
- Describe your product in plain English — "stainless steel water bottle" or "cotton t-shirts, men's, 200 units"
- Select the country of origin — the country where the product was manufactured, not shipped from
- Enter the goods value and estimated shipping — both are included in the dutiable value
- Get your full breakdown — HTS code, all tariff layers, MPF, HMF, and total landed cost in under 15 seconds
US Import Tariff Rates by Country (2026)
The country of origin determines which tariffs apply. Here's how the same product compares across common sourcing countries:
| Country | MFN | Section 301 | Section 232 | Section 122 | Total (est.) |
|---|---|---|---|---|---|
| China | ✓ | ✓ (7.5–100%) | If applicable | ✓ (10%) | Highest |
| Vietnam | ✓ | ✗ | If applicable | ✓ (10%) | Moderate |
| India | ✓ | ✗ | If applicable | ✓ (10%) | Moderate |
| Mexico | ✓ (USMCA may waive) | ✗ | If applicable | ✓ (10%) | Low–Moderate |
| Canada | ✓ (USMCA may waive) | ✗ | If applicable | ✓ (10%) | Low–Moderate |
Key insight: For Chinese-origin goods, Section 301 tariffs alone can add 25%–100% on top of the base MFN rate. A product with a 5% MFN rate imported from China with 25% Section 301 and 10% Section 122 faces an effective duty of roughly 40%+ before MPF and HMF.
Understanding HTS Codes
Every product imported into the US must be classified under an HTS (Harmonized Tariff Schedule) code. The HTS has 99 chapters organized by material and product type:
- Chapters 1–24: Agricultural products (live animals, meat, dairy, vegetables, beverages)
- Chapters 25–27: Minerals and fuels
- Chapters 28–38: Chemicals
- Chapters 39–40: Plastics and rubber
- Chapters 41–43: Leather and furs
- Chapters 44–49: Wood, paper, and printed materials
- Chapters 50–63: Textiles and apparel
- Chapters 64–67: Footwear and headgear
- Chapters 68–71: Stone, glass, and precious metals
- Chapters 72–83: Base metals (iron, steel, aluminum, copper)
- Chapters 84–85: Machinery and electronics
- Chapters 86–89: Transportation equipment
- Chapters 90–97: Instruments, furniture, toys, art
TariffCheck's AI analyzes your product description and matches it to the correct HTS chapter and heading — the same classification a licensed customs broker would use.
Section 301 Tariffs on Chinese Goods
Section 301 tariffs were originally imposed in 2018–2019 and significantly expanded in 2024. In 2026, they remain in full force on virtually all Chinese-origin goods.
| Product Category | Section 301 Rate | Typical Total Effective Rate |
|---|---|---|
| Consumer electronics | 25% | ~40–45% |
| Furniture and home goods | 25% | ~40–45% |
| Steel products | 25% | ~50–55% (+ 232) |
| Solar panels | 50% | ~65–70% |
| Semiconductors | 50% | ~60–65% |
| Electric vehicles | 100% | ~115–120% |
| Textiles and apparel | 7.5% | ~20–25% |
Section 122: The Expiring Surcharge
Starting April 2025, a 10% universal surcharge was applied to most US imports under Section 122 of the Trade Act. This surcharge expires July 24, 2026.
For businesses planning imports:
- Goods entering before July 24, 2026 will incur the 10% surcharge
- After expiry, this 10% drops off — reducing landed cost on a $10,000 shipment by $1,000+
- Plan shipment timing accordingly, especially for large orders
TariffCheck shows both your current landed cost and what it will be after the surcharge expires.
Landed Cost vs. Product Cost
Many importers focus only on product cost and miss the full picture. Landed cost includes:
- Product cost (FOB price or EXW + freight to port)
- Shipping and insurance (CIF or CPT to US port)
- All customs duties (MFN + special tariffs)
- Merchandise Processing Fee (MPF) — 0.3464% of customs value, min $31.67, max $614.35
- Harbor Maintenance Fee (HMF) — 0.125% of goods value (ocean only)
- Customs broker fee — typically $75–300 per entry (not included in TariffCheck estimate)
- Domestic freight — from port to warehouse (not included)
Example: Importing $5,000 worth of consumer electronics from China with $300 shipping:
| Cost Component | Amount |
|---|---|
| Product value | $5,000 |
| Shipping | $300 |
| MFN duty (3.9%) | ~$205 |
| Section 301 (25%) | ~$1,325 |
| Section 122 (10%) | ~$530 |
| MPF (0.3464%) | ~$185 |
| HMF (0.125%) | ~$6 |
| Total landed cost | ~$7,551 |
| Effective duty rate | ~51% of goods value |
Frequently Asked Questions
How accurate is TariffCheck?
TariffCheck provides AI-based estimates using 2026 tariff data. For informal entries under $2,500, accuracy is typically within 1–3%. For formal entries, the estimate gives you an accurate planning figure — always confirm with a licensed customs broker before importing.
What is the difference between MFN rate and total duty rate?
The MFN (Most-Favored-Nation) rate is the base duty that applies to all WTO member countries. The total duty rate adds Section 301 (China), Section 232 (steel/aluminum/autos), and Section 122 surcharges on top. For Chinese goods, the total can be 5–20x the MFN rate.
Do I need an HTS code to use TariffCheck?
No. Describe your product in plain English and TariffCheck's AI identifies the most likely HTS code. You can also enter an HTS code directly if you already know it.
What is a formal vs. informal customs entry?
Shipments valued over $2,500 require a formal entry filed by a licensed customs broker. Shipments under $2,500 are informal entries (de minimis over $800, informal between $800–$2,500). TariffCheck estimates apply to formal entries.
How often are tariff rates updated?
MFN rates change infrequently (typically through WTO negotiations). Section 301 rates have been updated several times since 2018. TariffCheck reflects the most current 2026 rates as of publication date.
Can I compare sourcing countries?
Yes. After calculating for your selected country, TariffCheck automatically shows you the landed cost for China, Vietnam, India, Mexico, and Thailand — so you can see exactly how much you'd save by shifting suppliers.
