Many Korea-origin goods qualify for reduced or duty-free treatment under KORUS; Section 232 applies to certain metals.
South Korea currently falls in the standard country tariff tier (about 10%), added on top of the base HTS duty and any Section 232 product measure.
Search your product below — we pull the base HTS rate live and stack the Section 232 / 301 and country measures that currently apply to South Korea. Use “Refine” for USMCA origin and product-form factors.

Importing goods from South Korea into the United States in 2026 means working through several stacked layers of duty, not a single number. Every shipment starts with the base ("most-favoured-nation") duty for its exact HTS classification, and then any additional national-security or trade measures are added on top. South Korea currently falls under the standard country tariff tier (currently around 10%).
Section 232 measures on steel, aluminium, copper, autos and semiconductors can stack on top where the product is covered, so the effective rate depends heavily on what you are importing — two goods from South Korea with different HTS codes can land at very different totals.
Because these measures change frequently through executive action, the only reliable way to price a shipment is to classify it to the correct HTS code, confirm its country of origin, and check which measures are in force on the entry date. The calculator above does exactly that — pulling the live base rate for your code and layering the current measures — but always confirm the final figure with a licensed customs broker before you file.
There is no single rate — it is the base HTS duty for your product plus any Section 232 product tariff and the current country tariff layer. Enter your product and shipment value in the calculator above to see the stacked estimate for South Korea.
Customs value × the combined rate. The calculator pulls the live base (MFN) rate for your HTS code, adds Section 232 where your product is covered, and adds South Korea's country tariff layer, then shows the total in dollars and as an effective percentage.
The base HTS rate is pulled live from our HTS database; the Section 232/301 and country-tier overlays are compiled from public sources and are provisional. Treat the result as a planning estimate and confirm current rates with USTR/CBP or a licensed customs broker before filing.
