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.

Trade Context

The US steel and aluminum industries are heavily protected by Section 232 tariffs. Canada and Mexico have quota-based exemptions, while most other countries face the full Section 232 rate.

Tariff Impact Summary

Steel and metals face the highest cumulative tariff rates in the entire HTS — up to 85% for Chinese steel (50% Section 232 + 25% Section 301 + 10% Section 122). Even non-China steel faces 60% (50% + 10%). These rates have fundamentally reshaped global steel trade flows.

Frequently Asked Questions

What is the tariff on steel from China?

Chinese steel faces 50% Section 232, plus 25% Section 301, plus 10% Section 122 = 85% total duty on top of any MFN base rate. This is among the highest effective tariff rates in the entire HTS.

Is Canadian steel tariff-free?

Canada has a tariff-rate quota under USMCA for steel. Within the quota, steel enters at 0% duty. Over-quota steel faces the full 50% Section 232 tariff plus the 10% Section 122 surcharge.

Why is the Section 232 rate currently so high?

Section 232 rates on steel and aluminum were doubled from 25% to 50% in 2025, citing persistent foreign overcapacity and insufficient recovery of domestic production. Some derivative steel articles under Chapter 73 are also covered.
