Lighting is one of the categories where the current tariff era can stack up, because decorative and household fixtures are often produced in a relatively concentrated set of overseas factories, and a base duty that was once minor may now sit underneath a heavier country-specific load. The category is also bulky and low-margin per unit, so freight and duty tend to move together, and even a few points of added duty can flip a fixture from profitable to underwater. Lighting SKUs are also easy to misclassify, and the wrong code can attach a meaningfully different rate to a product you have been selling for years.
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 lamp from South Korea at a 10% stacked rate, that means charging $39.60 to hold a 40% margin. Round to a clean price point and test it; the point is to stop selling underwater.
The core of lighting classification is HTS heading 9405, which covers luminaires and lighting fittings (lamps, ceiling and wall fixtures, string lights, and their parts) regardless of the light source. The base duty for many finished fixtures is relatively modest, but the rate that actually hits your landed cost tends to be driven by three attributes: the material of the fixture body (a brass or glass lamp may sit at a different subheading than a plastic one), whether the item is a complete fixture versus a part such as a shade or base, and the country of origin, which is what can pull in the heavier current-era load. Light sources themselves can fall outside the heading, which is one place rate surprises tend to come from. The exact per-SKU duty depends on the precise HS code, so two products that look identical on your storefront can carry different rates.
A common lighting pitfall is the LED line: an LED bulb or retrofit lamp is often classified outside the 9405 fixture heading (an electric lamp can fall under a different heading entirely), and an integrated LED module or driver may be pulled toward yet another heading. Merchants who file an entire lighting catalog under one 9405 code because everything ships as a 'lamp' can end up applying the wrong duty to their LED-source items, and because LED products are a growing share of many stores, that single misread can distort the margin on high-volume SKUs. When the bulb and the fixture ship together as one sellable unit, the classification can hinge on which component gives the article its essential character, so it is worth confirming the code per SKU rather than per category.
Lighting assembly is relatively mobile, which can make origin shifting more realistic here than in categories with concentrated raw-material supply, and some Southeast Asian countries already run fixture assembly lines that may change the country-specific load on your landed cost. The catch is that origin for duty purposes generally follows where substantial transformation happens, not where the box ships from, so moving final assembly while still importing the metalwork, glass, and electronics from a high-load origin may not move your rate the way you expect; that analysis is fact-specific. Before committing to a supplier change, price the same fixture against a few candidate origins and confirm the classification holds, since a heavy glass or metal fixture also carries freight cost that can erase a duty saving. This is general guidance, not a customs ruling, and the defensible answer for any specific SKU comes from its actual HS code and origin documentation.
Do string lights and seasonal fairy lights fall under the same heading as a table lamp?
Decorative lighting sets, including string and fairy lights, are generally captured within heading 9405 as lighting fittings, so they typically share the fixture base duty rather than a bulb rate. That said, battery-powered or novelty sets can fall under a different subheading depending on construction, and the country-specific load still applies on top. Confirm the exact code per product, because seasonal SKUs are often imported in bulk and a small rate difference can add up at volume.
Are replacement lampshades and fixture parts dutied differently from a complete lamp?
Parts of lighting fittings, such as standalone shades, bases, and arms, have their own provisions within the 9405 structure and can carry a different rate than the finished fixture they belong to. If you import components and assemble or kit them domestically, you may be classifying the parts rather than the complete lamp, which can change the duty and sometimes the country-of-origin analysis. It is worth treating parts SKUs as their own line in your costing rather than assuming they inherit the finished-fixture rate, and confirming the code per SKU.
My fixtures ship with the bulbs included. Does that change the tariff?
It can. When a fixture and its light source are imported together as one packaged article, classification may turn on which part gives the item its essential character, and an integrated-LED fixture can be treated differently than a traditional lamp sold with a separate replaceable bulb. Because the bulb side may pull in a code outside the 9405 fixture heading, a bundled product can land at a different rate than the bare fixture would. Check the combined article's code rather than assuming it follows the fixture alone.
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.
