Look Up US Import Tariffs for Electronic Components by Part Number

An HTS (Harmonized Tariff Schedule) code is the 10-digit number US customs uses to classify imported goods and set duty rates. The first 6 digits follow the international HS system; the last 4 are US-specific. Every electronic component imported into the US is entered under an HTS code.

Enter the manufacturer part number into PartGenie's tariff lookup. The AI identifies what the component is from catalog and datasheet data, then classifies it to the matching HTSUS heading and shows the reasoning — no need to read tariff chapter notes yourself.

It depends on the HTS classification. Many semiconductors and passives carry a 0% base MFN rate, but Section 301 tariffs add 7.5%–25% or more for China-origin goods, and other surcharges may apply on top. Enter your part number to see the current stacked rate for your component.

Section 301 tariffs are additional US duties applied to goods of Chinese origin under the Trade Act of 1974. They stack on top of the base MFN duty rate, so a component that is normally duty-free can still carry a 25% surcharge when it is made in China.

HS codes are the 6-digit international standard managed by the World Customs Organization and shared by most trading countries. HTS codes are the US 10-digit extension used to set exact duty rates for imports into the United States. PartGenie returns the US HTSUS code.

Yes — significantly. The same HTS code can be duty-free from one country and carry 25% or more from another once Section 301 and other origin-based programs apply. PartGenie shows rates by origin so you can compare sourcing scenarios before committing.

Yes. Upload your BOM in PartGenie and ask about tariff exposure — the assistant can classify lines and flag where origin drives cost. Pair it with the AI BOM Analyzer for risk and alternative coverage in the same pass.

No. PartGenie provides AI-assisted classification and duty estimates for planning and sourcing decisions. Final classification authority rests with US Customs and Border Protection; for binding certainty, request a CBP ruling or consult a licensed customs broker.
