Tools and hardware sit in supply chains that several recent tariff actions touch, so a category that long moved on a modest base duty can now see stacked China-origin and steel-and-aluminum measures added on top. A drill set, wrench kit, or box of fasteners that once cleared near the base rate may now carry additional layers depending on its origin and materials, and a large share of this category is still sourced from China. For a merchant selling at a fixed shelf price, much of that gap tends to be absorbed out of margin rather than passed cleanly to the buyer.
Representative 2026 estimate stacking base MFN duty (USITC HTS 2026 Rev.10), Section 301 on China-origin goods (USTR), Section 232 on autos and steel/aluminum/copper articles (CRS IN12545), and the 10% Section 122 surcharge that expires 2026-07-24 and is under appeal (Skadden). South Korea duty-free treatment requires meeting USMCA or KORUS rules of origin; non-qualifying goods pay standard MFN duty. Your exact per-SKU duty depends on the precise HS code, which MarginGuard resolves from the live HTS schedule once connected. Not legal or customs advice.
South Korea trades with the United States under KORUS, a free-trade agreement, which means most qualifying goods can enter duty-free provided they meet the agreement's rules of origin. For a Shopify merchant, that duty-free treatment can remove a line item from landed cost compared with sourcing from countries whose goods face standard or higher tariffs. The treatment is conditional: the duty-free rate applies only to goods that actually originate in Korea under KORUS criteria, not to anything merely shipped or finished there. Whether your specific product qualifies, and what rate applies if it does not, turns on its exact HS code and origin, so the representative rate shown on this page is a starting point rather than a quote for your SKU.
South Korea can be a lower-duty alternative to China when goods qualify, because KORUS allows qualifying goods to enter duty-free rather than at the variable and sometimes higher rates Chinese imports can carry. It carries its own trade-offs, and they fall mostly on cost-of-goods and capacity rather than tariffs: Korean manufacturing tends toward higher-value, higher-labor-cost output (electronics, cosmetics and skincare, auto parts, industrial components), so unit prices can run above Chinese equivalents and minimum order quantities may not suit very small runs. The main condition is rules of origin. A factory in Korea that assembles imported Chinese components may not produce a KORUS-originating good, which means the duty break you budgeted for may not apply. To source here for margin safety, confirm with your supplier that the product qualifies as Korean-origin under KORUS, obtain documentation to support that, and price in the higher base cost rather than assuming duty-free entry erases the difference. This is general guidance, not customs advice; verify eligibility with a licensed customs broker for your goods.
That's a single SKU. Across a full catalog the tariff hits every imported product differently depending on its cost and price — which is exactly why margin damage hides until a quarter closes light.
Paste your Shopify URL. In about ten seconds you'll see every SKU that dropped below your target margin after the current South Korea tariffs — and the exact price to charge to recover each one. Free, no login.

For a $50 tool set from South Korea at a 35% stacked rate, that means charging $56.25 to hold a 40% margin. Round to a clean price point and test it; the point is to stop selling underwater.
What usually moves the landed rate is not the base MFN line in HTS chapter 82 on its own; it is the layers that can be added on top based on origin and material.
For a mixed tool set, customs generally classifies the set under the General Rules of Interpretation (GRI 3) by the component that gives it its essential character, rather than applying a blended rate. Confirm the classification for your specific set.
In general, country of origin is determined by where substantial transformation occurs, not by where goods are repackaged. Treat this as general guidance and confirm origin for your specific products.
Why did the duty on my imported tools go up so much when the base rate is still only a few percent?
The base MFN duty under HTS chapter 82 has not changed much, but a large share of tools and hardware ships from China, which can carry Section 301 tariffs along with newer reciprocal-tariff actions on top of that base rate. Steel-bodied tools may also pick up a Section 232 layer. Those stacked layers, not the base line, are typically what drive landed cost up, and the exact total depends on your specific HS code and origin.
Are hand tools and power tools treated differently for tariff purposes?
Often, yes, and it can matter. Non-powered hand tools generally sit in HTS chapter 82, while a tool with its own electric or pneumatic motor often falls under chapter 84 or 85, which can carry a different base rate and different Section 232 steel exposure. If you sell both, do not assume one duty rate covers your whole catalog, and confirm the heading for each powered SKU separately.
Will moving production out of China actually lower my duty on hardware?
It can, but generally only if the goods are genuinely produced or substantially transformed in the new country, not just repackaged or relabeled there. Country of origin generally follows where the substantial transformation happens, so Chinese-made tools routed through a third country can keep their Chinese origin and the associated tariffs. As general guidance, confirm that any alternate source represents real production rather than transshipment, and keep documentation such as mill certificates and bills of materials to support the origin you claim at entry.
Do goods from South Korea really enter the US duty-free?
Most qualifying goods can, under the KORUS free-trade agreement. The key word is qualifying: duty-free treatment applies only to goods that meet KORUS rules of origin, not to everything shipped from Korea. Goods that do not qualify fall back to the standard tariff rate for their exact HS code. Confirm your specific product's eligibility before assuming the duty-free rate, and treat the rate shown on this page as a representative figure rather than a quote for your SKU. This is general guidance, not customs advice; verify with a licensed customs broker for your goods.
What makes a product count as 'Korean origin' for the KORUS duty break?
Origin is determined by KORUS rules of origin, not just by where the item ships from or where final assembly happens. Generally a good must be either wholly produced in Korea or substantially transformed there, often with a minimum share of qualifying materials or a required change in tariff classification. A product assembled in Korea from largely imported components may not qualify. Ask your supplier whether the item meets KORUS origin criteria and can supply origin documentation to support a claim. This is general guidance, not customs advice; verify with a licensed customs broker for your goods.
Is sourcing from South Korea cheaper overall than from China?
Not necessarily on unit cost. KORUS can remove or reduce the tariff line that Chinese imports may face, which helps landed cost, but Korean goods often carry higher base manufacturing prices and sometimes higher minimum order quantities. Whether Korea wins on total landed cost depends on your product, order volume, and whether the goods actually qualify for duty-free entry, with the applicable rate turning on the exact HS code. Run the full landed-cost comparison, duty plus unit price plus freight, rather than assuming the duty advantage alone makes Korea the cheaper option. This is general guidance, not customs advice; verify with a licensed customs broker for your goods.
