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.

US Tariff Rates on Imports from Canada

Canada follows the same USMCA-or-IEEPA bifurcation as Mexico. USMCA-compliant goods enter at 0%; non-compliant goods carry the 25% IEEPA-derived surtax (10% on covered energy and potash).

Energy products — the carve-out that matters

Canadian crude oil, natural gas, electricity, refined fuels, and potash benefit from a 10% IEEPA rate rather than the 25% general rate when not USMCA-qualified. The USMCA itself sets 0% on most energy, so the carve-out matters mostly for non-qualifying flows.

Crude oil (HTS 2709): 0% under USMCA when refinery-of-origin rules met.
Lumber (HTS 4407, 4409): historically subject to softwood lumber AD/CVD orders independent of USMCA status.
Electricity, natural gas: 0% under USMCA; 10% IEEPA otherwise.

Lumber and softwood — separate AD/CVD layer

Even when USMCA-qualified, Canadian softwood lumber is subject to AD/CVD orders that have been in place since 2017 and renewed periodically. Combined AD + CVD rates have ranged from 8% to 20% depending on the producer and review cycle. Track the current order via /pulse for updates.
