HTS-8 Tariff Calculator

This lookup finds a product's 8-digit HTS line and estimates duty as shipment value × that line's trade-weighted additional tariff rate. It covers 10,888 HTS-8 lines from the "Imposed Tariff Rate by Product Set" file published with the Penn Wharton Budget Model tariff simulator, last updated June 9, 2026. It is for informational purposes only. The rate is an estimate for planning, not the duty CBP will assess on your entry.

If you're not sure which line fits your product, read how to find your HTS code first. Choosing the wrong line is a bigger error than any rounding in the rate.

How to use the HTS lookup

1. Search by code or keyword. Type a code stem such as 7208 (flat-rolled steel) or a word from the official description such as aluminum. The list shows up to 40 matches, so add digits or words to narrow it.
2. Select the best-matching line. The 8-digit code and description are the legal tariff line. Read the whole description, since many lines differ only by size, value, or material.
3. Enter the shipment value. Use the customs value: the price paid to the supplier, excluding international freight and insurance when they are invoiced separately.
4. Read the estimate. Duty = shipment value × the line's rate.
5. Add the General rate. Look up the same 8-digit line on the USITC Harmonized Tariff Schedule and add its General column rate, unless you qualify for a Special rate.

Search tips for HTS descriptions

Official descriptions are terse and abbreviated, so plain-English searches can miss. Try:

• Root words: refrigerat matches refrigerators and refrigerating. footwear finds more than shoes.
• HTS shorthand: nesoi (not elsewhere specified or included), o/than (other than), w/ (with), pts. (parts).
• Material first: copper wire rather than electrical wire, because the schedule is organized by material before function in many chapters.
• Code stems: the first 4 digits (the heading) bring up every line in the family, so you can compare neighbors.

What the rate in this tool represents

The figure shown for each line is a trade-weighted average of the additional tariffs imposed since 2025, across all countries that ship that product to the United States. Three implications:

• It excludes the base General (MFN) rate. Line checks against the HTS confirm this. A pickup truck (8704.21.01) shows 0.74% here, but its General rate is 25%. Rubber-soled footwear (6402.99.31) shows 9.91%, plus a 6% General rate.
• It blends countries of origin. Cars under 8703.23.01 show 9.52%, a mix of USMCA-qualifying vehicles, partners with negotiated auto rates, and the full 25% Section 232 rate. Your rate depends on your origin.
• It is a snapshot from June 9, 2026. At that point the 10% Section 122 surcharge applied to most non-exempt goods. It expired July 24, 2026 and was replaced by Section 301 duties of 10% for 17 economies, including Canada, Mexico, India, and the UK, and 12.5% for most others, including China and Vietnam.

How the 10,888 lines are distributed

Most lines cluster between 5% and 10%, which reflects the old 10% surcharge averaged with exempt or duty-free origins. The 688 lines at 25% or higher are almost all Section 232 goods: metals, metal derivatives, autos, and wood products.

Worked examples from the lookup

Example: $25,000 of hot-rolled coil. Duty = $25,000 × 50% = $12,500. The General rate is free, so the tool's estimate is the full planning figure. Hot-rolled steel is a Section 232 article, so the July 2026 Section 301 duty does not add to it.

Example: $25,000 of leather-upper footwear. The tool gives $25,000 × 9.94% = $2,485. Adding the 10% General rate brings it to $25,000 × 19.94% = $4,985, twice the tool's figure. For a shoe from a country in the 12.5% Section 301 group after July 24, 2026, plan on about 22.5%: 10% + 12.5%, or $5,625.

Example: copper, two lines apart. Cathode (7403.11.00) shows 0%, while wire (7408.11.30) shows 50%. Under Proclamation 11021, semi-finished copper is covered and refined cathode is not. A $100,000 order costs $0 or $51,000 in duty depending on which line it falls under.

Reading the result card

After you select a line, the Selected Code Estimate card shows three things:

• HTS-8 code and description: the line you picked. Make sure the description matches your product's material, size, and value range before you go further.
• Weighted rate: the trade-weighted additional tariff for that line, to two decimals.
• Estimated duty: shipment value × weighted rate, rounded to the dollar.

The data date, currently June 9, 2026, appears under the search box along with the number of codes loaded. Write it next to any number you copy into a quote or budget, so anyone reading the quote later knows which tariff regime it reflects.

A rate with decimals, such as 9.94% or 24.6%, almost always means the line is shipped from a mix of origins with different treatment. A round 10%, 25%, or 50% usually means nearly all trade on that line faced the same rule.

How to see which Chapter 99 duties apply to a line

The tool gives one blended number. To see the legal pieces behind it, open the same line on hts.usitc.gov and check its footnotes, which point to Chapter 99 headings. Then read the matching notes in Chapter 99. The headings to know in 2026:

Your broker reports the applicable Chapter 99 number on the entry next to the product's 10-digit code. If no footnote points to Chapter 99 and your origin isn't covered by a trade action, the General rate is the whole duty.

When the line rate needs adjusting

Adjust the tool's rate before relying on it if any of these apply:

• Origin in China: the 2018–2019 Section 301 duties (USTR tariff actions) still apply on top, typically 7.5% or 25%.
• Origin in the 12.5% Section 301 group: add about 2.5 points for non-Section 232 goods entered after July 24, 2026.
• USMCA-qualifying goods from Canada or Mexico: the General rate may be free and the new Section 301 duty doesn't apply. Your rate may be below the average.
• Patented pharmaceuticals: chapter 30 lines show near 0% here, but Proclamation 11020 imposed up to 100% from July 31 or September 29, 2026, depending on the company.
• Wooden furniture: lines 9403.40.90 and 9403.60.80 show 45–46%, and upholstered wooden chairs (9401.61.40) about 29%. Those numbers match the 50% and 30% step-up rates that were postponed to January 1, 2027, applied to whole lines. Until then the Section 232 rate on cabinets, vanities, and upholstered wood furniture is 25%, and other wooden furniture on those lines, such as dining tables, is outside the wood action entirely.
• Antidumping or countervailing duty orders: check whether your product and producer are covered. These deposits can exceed the tariff itself.
• Specific or compound rates: some General rates are per unit, such as cents per kilogram or per pair. Convert them to a percentage of your unit value before adding.

How the HTS lookup relates to other tools

• The category tariff calculator blends these line rates into 22 chapter-level averages. Use it before you know the code.
• The importer landed cost calculator takes the combined rate from here and adds freight, fees, and your selling price to show margin impact.
• The highest tariff product categories page explains which policies push certain chapters to the top.

What this tool does not do

It doesn't classify products for you, file entries, claim trade-agreement preferences, or apply antidumping and countervailing duty orders. It doesn't track rate changes made after June 9, 2026. For any entry with material duty at stake, confirm the classification and the full stack of rates with a licensed customs broker, or with a CBP binding ruling.
