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). Mexico 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.
Goods from Mexico that qualify under the United States–Mexico–Canada Agreement (USMCA) generally enter the US duty-free, which is one reason Mexico is often cited as a nearshoring option for merchants trying to reduce exposure to the China tariff stack. Because Mexico is land-adjacent to the US, sourcing there can also mean shorter transit, lower freight per unit, and faster replenishment cycles than transpacific routes. For landed cost, the appeal is that a properly qualifying product can avoid the regular duty and the additional China-specific tariff layers that apply to comparable imports; the exact rate that would otherwise apply depends on the product's HS code. The catch is that duty-free treatment is not automatic by virtue of shipping from Mexico; it depends on whether the specific good meets USMCA rules of origin.
Mexico can be a viable alternative to China for many categories, but generally only when the product actually originates in Mexico under USMCA rather than being merely shipped or lightly finished there. The key issue is rules of origin: if a supplier is essentially importing Chinese inputs, doing minimal assembly, and re-exporting, the good may not qualify for USMCA duty-free treatment and can still face regular duties, so the China stack you were trying to avoid can effectively follow the components in. Qualifying typically requires meeting the applicable tariff-shift or regional-value-content threshold for the product, plus a valid USMCA certification of origin from the producer or exporter kept on file in case of a customs review. It is reasonable to scrutinize unusually low quoted prices until you can confirm where the inputs come from and whether the finished good meets the origin test for its category. Done carefully, Mexico can pair duty savings with proximity advantages; done carelessly, it risks being a relabeling exercise that leaves landed cost exposed. This is general guidance, not customs or legal advice.
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.

For a $45 lamp from Mexico at a 0% stacked rate, that means charging $36.00 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.
Are all goods from Mexico duty-free into the US?
No. Duty-free entry generally applies to goods that qualify under USMCA's rules of origin, not to everything shipped from Mexico. A product made largely from non-originating inputs with only minor processing in Mexico may fail the origin test and still owe regular duties, at a rate that depends on the product's HS code. Confirm with your supplier whether the specific item meets USMCA origin rules and can be supported by a certification of origin before assuming a zero rate. This is general guidance, not customs or legal advice.
What do I need from my Mexican supplier to claim USMCA treatment?
You generally need a valid USMCA certification of origin from the producer, exporter, or importer attesting that the good qualifies, along with supporting records on the materials and where they came from. Keeping this documentation on file matters because US Customs can request it to verify the claim. Without it, the importer of record may not be able to substantiate duty-free treatment if the entry is reviewed. This is general guidance, not customs or legal advice.
Does sourcing from Mexico really avoid the China tariffs?
It can, but generally only if the product genuinely originates in Mexico under USMCA rather than relying on Chinese components passed through with minimal transformation. If the inputs are predominantly Chinese and the good does not meet the applicable tariff-shift or regional-value threshold, the savings you expected may not materialize. A practical way to protect margin is to verify the supply chain and origin qualification, not just the country listed on the shipping label. This is general guidance, not customs or legal advice.
