Fitness equipment sits in a category where landing costs have shifted under the current tariff environment, in part because a large share of imported treadmills, dumbbells, benches, and resistance machines has historically come from China, an origin that has carried some of the steepest stacked add-on duties under recent measures. A piece that cleared at a modest base rate a couple of years ago may now arrive with additional layers on top, and those layers are generally charged on the full customs value, not your wholesale cost. For a heavy, low-margin good that already carries significant freight, even a few points of added duty can be enough to move a SKU from profitable to unprofitable.
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 $75 piece of equipment from South Korea at a 10% stacked rate, that means charging $68.75 to hold a 40% margin. Round to a clean price point and test it; the point is to stop selling underwater.
The base duty for most general exercise and gym equipment falls under HTS chapter 95 (heading 9506, "articles and equipment for general physical exercise, gymnastics, athletics"), and much of that subheading can carry a relatively low or even free general rate, so the base MFN duty may be only a small part of the total. What tends to move your total landed rate is country of origin, because origin is what can trigger Section 301 China add-ons (where they apply) and any applicable newer reciprocal-tariff layers on top of the base rate. Composition and function also matter: a steel weight plate, a powered treadmill with an electric motor, a rubber-coated kettlebell, and an electronic fitness tracker built into a machine can each pull toward different chapters (for example chapter 73 for plain steel articles, chapter 85 for motorized or electronic components), and the classification of the motor or electronics can carry its own duty. A key driver to pin down is origin and the precise heading, since the exact per-SKU rate depends on the specific HS code, and it is worth confirming yours rather than assuming a category average.
A common pitfall is defaulting everything to the 9506 "general exercise equipment" bucket when the item is really driven by a different material or component. Plain cast-iron or steel dumbbells, kettlebells, and weight plates with no mechanism may be classifiable as articles of iron or steel under chapter 73 rather than under 9506, and that distinction can change the base rate and which add-ons apply. The same issue can affect motorized and "smart" equipment: a treadmill's electric motor or a machine's built-in console and sensors can pull the item, or its parts, toward chapter 85 electronics. As a general matter, classification follows what the article actually is and how it functions, not the marketing label "fitness." A licensed customs broker can confirm the classification, and a binding ruling is an option, before committing to large orders.
Because origin is a major lever here, one option worth weighing is shifting sourcing away from the origin carrying the steepest add-ons toward suppliers in countries that face only the base rate. For commodity gear like benches, racks, mats, resistance bands, and basic free weights, manufacturing exists across Vietnam, Taiwan, India, and elsewhere, so this category may have more alternate-origin options than some. Two things are worth watching when you switch: substantial transformation rules generally mean that simply assembling or relabeling Chinese parts in a third country does not, on its own, change the origin for duty purposes, and the freight math on heavy steel goods can erase a duty saving if the new lane has worse shipping economics. It is worth running the full landed-cost comparison, including freight and any anti-dumping exposure on steel components, before moving volume.
Why did the duty on my treadmills jump when the base rate for exercise equipment is supposed to be low?
A low base rate under heading 9506 is only the starting point. If your treadmills are made in China, Section 301 and any applicable newer reciprocal-tariff layers can stack on top of that base, and such add-ons are generally charged on the full declared customs value. In a case like this, origin, rather than the category, is typically what drives the jump, which is why the same model from a different country may land at a very different total rate. Your exact rate depends on the specific HS code, so it is worth confirming with a customs professional.
Are plain steel dumbbells and weight plates classified the same as a rowing machine or treadmill?
Often not. A simple cast-iron or steel dumbbell or plate with no mechanism may be classified as an article of iron or steel under chapter 73 rather than as exercise equipment under chapter 95, while a powered machine may pull in chapter 85 electronics for its motor or console. Because each can carry a different base rate and different add-ons, the per-SKU duty depends on the specific HS code, so it is worth confirming each product's classification rather than treating your whole catalog as one rate.
If I move my gym equipment factory from China to Vietnam, do the extra tariffs go away?
They may, but generally only if the goods genuinely originate in Vietnam under the substantial transformation rules. Shipping Chinese-made parts to Vietnam for light assembly or relabeling typically does not change the country of origin for duty purposes, so the China add-ons may still apply. Keeping records of the manufacturing steps and weighing the freight cost of the new lane both help, since heavy steel goods can lose the duty saving to worse shipping economics. For a specific move, it is worth confirming the origin treatment with a customs professional.
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.
