Apparel runs on thin retail margins, and most garments sold by Shopify merchants are produced overseas, so a typical item crosses a border and absorbs duty before it reaches a customer. This category has historically carried some of the higher baseline rates in the US tariff schedule, and recent country-specific surcharges layered on top of that base can hit clothing harder than many other goods. When the landed cost of a garment moves, a cheaper domestic alternative is often not available to pivot to, which is why a tariff change tends to show up directly in your unit economics.
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 $45 jacket from South Korea at a 10% stacked rate, that means charging $41.25 to hold a 40% margin. Round to a clean price point and test it; the point is to stop selling underwater.
Apparel is classified largely under HTS Chapters 61 (knitted or crocheted garments) and 62 (woven, not knitted), and the split between those two chapters is often the first thing that moves your rate. From there, duty is typically driven by the dominant fiber by weight (cotton, wool, man-made fiber, or silk), the construction (knit vs woven), the garment type, and gender or age cut, so a women's woven cotton blouse and a men's knit synthetic shirt can land on very different lines. The exact per-SKU rate depends on the full HS code, not the category average, and the same physical item can plausibly fall under more than one code until you confirm the fiber content and construction.
A common and costly mistake is misreading fiber content on blends: classification generally follows the fiber that predominates by weight, so a garment that is 60% polyester / 40% cotton is typically duty-rated as man-made fiber, not cotton, even if it looks and feels like a cotton tee. Merchants sometimes pull a code straight from a supplier's loose description and get the chapter or fiber basis wrong, which can change the rate meaningfully and can lead to back-duty if CBP later reclassifies it. As general guidance, confirm the actual content-label percentages, the knit-versus-woven construction, and whether trim or coatings push the item to a different heading before you rely on any code.
Apparel sourcing is relatively mobile, since cut-and-sew and knit capacity exists across many countries, so origin shopping can be a real lever here in a way it often is not for niche specialty goods. As a general rule, origin is set by where the garment is substantially transformed (commonly where it is cut and sewn) rather than where the fabric or the brand is from, though the specific substantial-transformation and origin rules vary by program and country, and some programs add yarn-forward rules that look further up the supply chain. Treat this as general guidance, not legal or customs advice, and price in the full landed cost per origin: a unit price that looks lower from a higher-tariff country can erase its own savings once duty is applied.
Why is the duty on my clothing higher than on other products I import?
Apparel has historically carried elevated baseline rates in the US schedule, and these tend to be higher than the average for many other consumer goods, in part because clothing has historically been treated as a protected category. Recent country-specific surcharges can stack on top of that base, so garments often absorb more duty than electronics or housewares from the same supplier country. That combination is why a small rate change can move your clothing margin noticeably. The exact rate still depends on the specific HS code for each item.
My supplier gave me an HS code. Can I just use it?
A supplier's code is generally a starting point, not a guarantee. As a general matter the importer of record is responsible for correct classification and can bear the cost if CBP disagrees, so it is worth verifying. Suppliers sometimes default to a familiar code or mislabel blend percentages, and the right line depends on confirmed fiber content, knit-versus-woven construction, and garment cut. Check it against the actual content label and the Chapter 61 or 62 headings before relying on it for landed-cost math. This is general guidance, not legal or customs advice.
Does changing where my clothes are made actually lower the tariff?
It can, because the rate depends on country of origin and apparel assembly is relatively mobile across many countries. As a general rule, origin is determined by where the garment is substantially transformed, usually where it is cut and sewn, rather than where you buy it or where the brand sits, though the specific origin rules vary and are worth confirming against current guidance. Some trade programs add yarn-forward or fabric-origin rules that require earlier supply-chain steps to qualify for a preferential rate. Compare the full landed cost per origin rather than the unit price alone, since a cheaper factory in a higher-tariff country can give back its savings in duty.
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.
