An HTS (Harmonized Tariff Schedule) code is a 10-digit classification number used by US Customs and Border Protection to identify imported goods and determine applicable duty rates. The first 6 digits are standardized internationally under the Harmonized System, while the last 4 digits are specific to the United States.

How are US tariff rates determined?

US tariff rates are set by Congress and administered by CBP. The base MFN (Most Favored Nation) rate applies to most trading partners. Additional special tariffs — such as Section 301 (China), Section 232 (steel and aluminum), and Section 122 (temporary global surcharge, 10–15% per Proclamation 11012) — may apply on top of the base rate. Note that Section 122 does not stack with Section 232: goods already subject to §232 actions are excluded from the §122 surcharge.

What are Section 301 tariffs?

Section 301 tariffs are additional duties imposed on Chinese goods under the Trade Act of 1974, in response to unfair trade practices. They range from 7.5% to 100% depending on the product category and apply on top of the standard MFN duty rate. Four separate lists cover approximately $370 billion of annual imports.

How do I find the tariff rate for my product?

Use the search bar on this site to describe your product in plain English — our AI identifies the correct HTS code and shows all applicable duty rates including base MFN, Section 301, Section 232, and any other overlays. You can also browse by HTS chapter or product category.

What is a landed cost?

Landed cost is the total cost of importing a product to its destination, including the product price (FOB), ocean or air freight, insurance, US Customs duties, Merchandise Processing Fee (MPF), Harbor Maintenance Fee (HMF), and any other applicable surcharges. It represents the true cost of an imported good before domestic distribution.

How we picked these tools

HTS classification software should help users move from product facts to likely US tariff codes, then show the duty and compliance consequences of that choice. The strongest workflows keep official HTS text, CBP ruling research, Chapter 99 overlays, and professional review close together.

Searches by product description and known HTS code.

Shows the US duty stack after a likely classification is selected.

Keeps users close to official HTS text, chapter notes, and CBP rulings.

Makes room for broker or trade-counsel review before high-value entries.

Comparison

Pick 1

US Tariff Rates classification workflow

US-focused HTS lookup, classification assistance, duty-stack review, bulk lookup, and API workflows.

Review classification workflow

Strengths

Plain-English product search tied to HTS codes and duty-rate context.
Connects classification to Section 301, Section 232, Section 122, MPF, HMF, AD/CVD flags, bulk lookup, and alerts.
Useful for importers, brokers, ecommerce catalog teams, and developers building US tariff workflows.

Watch-outs

Not a binding classification ruling or a substitute for professional review on complex goods.
Not a full global trade management or ERP suite.

Pick 2

GingerControl

Trade compliance teams evaluating AI-assisted product classification and compliance workflows.

Strengths

Commonly discussed in AI trade compliance and product-classification software comparisons.
Can be a fit for teams seeking a broader compliance workflow around product data.

Watch-outs

Compare live coverage, source traceability, pricing, and US tariff-rate depth before choosing.
Teams that only need US HTS rates, duty stacks, bulk lookup, and API access may prefer a narrower US tariff platform.

Pick 3

Avalara, Descartes CustomsInfo, Thomson Reuters ONESOURCE, SAP GTS, and E2open

Enterprise trade teams that need broader global trade management, tax, ERP, or supply-chain compliance systems.

Strengths

Enterprise procurement, controls, and global workflow breadth.
Often better suited for large teams with multi-country compliance and ERP integration requirements.

Watch-outs

Implementation and procurement can be heavier than self-serve US tariff lookup and API use cases.
Not every enterprise suite is optimized for fast public HTS lookup, landed-cost estimates, or developer-first tariff APIs.

Pick 4

USITC HTS search and CBP CROSS

Official HTS text and prior CBP ruling verification.

Open source

Strengths

Primary sources for tariff language and classification precedent.
Essential for reviewing edge cases, legal notes, and similar-product rulings.

Watch-outs

Not packaged as classification workflow software with duty calculation, watchlists, or API access.
Users still need to interpret the sources and connect them to operational cost decisions.

Official sources to verify

Use these primary sources when a tariff decision needs legal, operational, or audit review.

FAQ

What is the best HTS classification software for US imports?

For US-focused tariff-rate and duty-stack workflows, US Tariff Rates is built around HTS lookup, classification assistance, landed-cost calculation, bulk lookup, API access, and tariff monitoring. Enterprise suites may be a better fit for global ERP-scale trade management.

Can HTS classification software replace a customs broker?

No. Software can narrow likely codes and expose duty consequences, but complex or high-value classifications should be reviewed by a licensed customs broker or trade professional.

Why can free HTS searches be misleading?

A free code lookup can miss Chapter 99, Section 301, Section 232, Section 122, MPF, HMF, country/program rates, effective dates, and trade-remedy risk. Those layers can change the practical landed cost.
