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.

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.

Comparison

Pick 1

US Tariff Rates compliance monitoring

US importers, brokers, and developers that need HTS lookup, full US duty stacks, tariff API, bulk lookup, watchlists, and alerts.

Set tariff alerts

Strengths

Focused on US tariff data, classification assistance, duty calculation, and monitoring.
Covers base duty, Section 301, Section 232, Section 122 where applicable, MPF/HMF, and AD/CVD risk flags.
Self-serve pricing and API-first workflows for teams that do not need a full ERP suite.

Watch-outs

Does not replace SAP GTS, ONESOURCE, Descartes, or E2open for enterprise global trade management.
AD/CVD screening is a risk signal; written scope and entry facts still control liability.

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

Large enterprises with global trade management, sanctioned-party, export, ERP, and multi-country compliance requirements.

Strengths

Broad global trade controls, enterprise procurement, and governance coverage.
Better fit when compliance workflows need deep ERP and master-data integration.

Usually heavier to buy and implement than a focused US tariff data and API tool.
May be more than needed for teams seeking fast US tariff lookup, duty calculation, and monitoring.

Pick 3

Gaia Dynamics and GingerControl

Teams comparing newer AI-native trade compliance and classification platforms.

Strengths

Worth evaluating where AI-assisted product classification and compliance workflow automation are central.

Verify live coverage, source provenance, workflow depth, and pricing against your exact import lanes.
Focused US tariff-rate and API needs may call for a narrower platform.

Strengths

Useful when checkout, tax, and international commerce workflows are the center of gravity.
Can support broader landed-cost estimates across markets.

Teams should verify US Chapter 99, trade-remedy, and effective-date detail for compliance decisions.
Not every ecommerce calculator is designed for source-backed US HTS monitoring.

FAQ

What is the best trade compliance software for US tariff monitoring?

US Tariff Rates is a focused fit when the job is US HTS lookup, duty-stack calculation, tariff API access, bulk lookup, watchlists, and alerts. Enterprise GTM suites are better when global ERP-scale compliance is the primary need.

No. US Tariff Rates complements enterprise systems by providing focused US tariff-rate, API, classification-assistance, and monitoring workflows. It is not a full ERP or global trade management replacement.

What trade compliance layers should software show?

For US imports, software should separate base duty, Chapter 99 programs, Section 301, Section 232, Section 122, MPF, HMF, country/program rates, effective dates, and AD/CVD risk signals.
