Eyewear is a category where the headline duty is modest but the stacked landed cost may not be, because much of the production base sits in origins now carrying additional tariff layers. A meaningful share of sunglasses and frames is produced in China, where Section 301 duties and any current US tariff actions that apply can layer on top of the base rate, so a low single-digit base duty can translate into a noticeably higher effective rate per unit. For a low-AOV accessory often bought on impulse, that gap tends to land on margin rather than being absorbed in a high sticker price. The exact figure depends on the specific ten-digit HS code and the country of origin.
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). 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.
China is the highest-stacked common sourcing origin into the US, because duties tend to layer on top of one another rather than replacing each other. A China import can carry the normal HTS base rate, Section 301 tariffs that apply to many goods from China, and current reciprocal-era duties, and where they apply those layers can compound on the same customs value. The practical result is that the listed product duty rate often does not tell the whole story, and the gap between an order's invoice cost and its true landed cost can be wider for China than for many other origins. The combined rate depends on the exact HS code, so for margin planning that stacking is a leading reason a China-sourced SKU can look profitable on paper and still lose money after it clears customs.
China is often not the margin-safe choice on tariff exposure alone, since it carries one of the heaviest stacked-duty loads among the common origins, so the honest framing is that it tends to compete on unit cost, supplier depth, tooling, and speed rather than on landed-cost advantage. The catch with staying in China is duty volatility: Section 301 lists and reciprocal-era rates are set by policy and can change in ways you do not control, so a margin that works today can compress if rates move. The catch with leaving is that lower-tariff alternatives (for example in parts of Southeast Asia) often carry their own load, including higher per-unit pricing, longer qualification, thinner supplier networks, and closer review of whether goods are genuinely transformed there versus merely transshipped from China. Before assuming any alternative origin or trade program lowers your duty, confirm the product actually meets that country's rules of origin for its specific HS code, because qualifying is not automatic. A durable approach is to model total landed cost per SKU under each origin, keep a second qualified supplier outside China for your tariff-sensitive lines, and treat China's rate as something to monitor over time rather than set once. 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 $30 pair of sunglasses from China at a 37.5% stacked rate, that means charging $24.06 to hold a 40% margin. Round to a clean price point and test it; the point is to stop selling underwater.
These goods sit in Chapter 90 (optical instruments), usually heading 9004, with frames and mountings imported on their own generally falling under heading 9003. A primary driver of the effective rate is often country of origin rather than the base duty alone: China-origin eyewear can stack Section 301 plus any current US tariff actions that apply on top of the base rate, while goods qualifying under a trade preference may land lower. Within 9004 the rate also depends on what the article actually is at the eight- and ten-digit level: sunglasses with a tinted, UV-filtering lens (9004.10) are generally treated differently from other corrective or protective spectacles and clear-lens readers (9004.90), and value, materials, and whether the lens is prescription can each affect the precise per-SKU number. Because the exact rate turns on the full ten-digit code and the origin, treat any single percentage as indicative and confirm the line for your specific product.
A recurring trap is the line between 9004.10 (sunglasses) and 9004.90 (other spectacles), and it can be misread in both directions. Blue-light-blocking glasses and clear-lens readers with no meaningful tint are generally not sunglasses and typically belong in 9004.90, while a tinted, UV-filtering lens generally pulls the article into 9004.10 even when it also carries a prescription or fashion styling. A second pitfall is shipping frames separately: empty fashion frames and frame components generally classify under 9003, not 9004, so a "sunglasses" SKU brought in as frames-plus-lenses on different lines can be classified and rated differently than the assembled finished product. If you are unsure how a split shipment should be classified, confirm the treatment with a licensed customs broker before relying on it.
Origin is often what moves landed cost most in this category, because the added duty layers tend to be origin-driven rather than product-driven. Eyewear assembly has a credible footprint outside China, with sunglasses and frame production established in places such as Italy and growing capacity in Vietnam, so sourcing the same design from a non-China origin may reduce the surcharge layer that dominates the China figure. Whether an origin claim holds generally turns on where the lens and frame are actually assembled and finished rather than where a label is applied, so confirm any origin claim is defensible with a customs professional before counting on it. Even within China sourcing, confirming your ten-digit code, reviewing order structure, and reviewing valuation methods such as first-sale where they genuinely apply may help, though each should be confirmed with a customs professional rather than assumed.
Are sunglasses and prescription glasses classified the same way for duty?
Not exactly. Both generally sit in heading 9004, but sunglasses with a tinted, UV-filtering lens typically fall under 9004.10 while non-sun corrective and protective spectacles, including clear-lens readers, typically fall under 9004.90. A tinted prescription sunglass is generally still treated as a sunglass under 9004.10, so the UV-filtering tint, not the prescription, is usually what drives the subheading. Confirm the exact ten-digit code for your specific product.
Why is my eyewear import cost so much higher than the base duty rate suggests?
The base duty for this category is relatively low, but it is often not the whole story. China-origin eyewear can stack Section 301 duties and any current US tariff actions that apply on top of that base rate, so the effective rate per unit can be materially higher than the headline number. Model the stacked rate for your specific origin and ten-digit HS code rather than relying on the base line alone.
Does importing frames and lenses separately reduce my duty?
It generally changes the classification rather than reliably reducing the cost, and it can backfire. Empty frames and mountings generally classify under heading 9003, separate lenses may classify elsewhere, and assembled sunglasses generally sit in 9004, so splitting a finished product into components shifts which rate applies and may prompt a reclassification on review. Confirm the correct ten-digit code for how the goods actually arrive, ideally with a licensed customs broker, before assuming a component split saves money.
Why is sourcing from China more expensive on duties than other countries?
Often because the duties stack. A China import can carry its normal HTS base rate, Section 301 tariffs that apply to many goods from China, and current reciprocal-era duties at the same time, and where they apply those layers can compound on the same customs value rather than replacing one another. That compounding is a key reason China is the highest-stacked common sourcing origin into the US, and it is why the product's listed duty rate can understate what you actually pay at the border. The combined rate depends on the exact HS code, so check the combined rate for your specific HTS classification rather than the headline figure.
Should I move my sourcing out of China to avoid the tariffs?
Maybe, but run the full landed-cost math first instead of assuming an alternative is cheaper. Lower-tariff origins often offset their duty advantage with higher unit prices, longer lead times, smaller supplier bases, and qualification work, so the all-in cost can land close to China for some products. A second consideration is rules of origin: goods generally get an alternative country's treatment only if they are substantially produced or transformed there, not simply routed through it, and that determination depends on the specific HS code. The right answer is usually SKU-by-SKU, and a safer position is a qualified backup supplier outside China for your most tariff-sensitive lines. This is general guidance, not customs or legal advice.
Could the tariffs on Chinese goods change again?
They could, and planning for that is part of sourcing from China carefully. Section 301 tariff lists and reciprocal-era duty rates are set by policy and can be adjusted in ways no merchant controls, which is part of why China-sourced margins can be more exposed to rate changes than some other origins. Treat your current China rate as a number to monitor rather than a fixed input, and revisit landed cost whenever rates shift. Because the live combined duty rate depends on your exact HS code, confirm it before committing to a large order, since the rate at quote time may not be the rate at arrival. This is general guidance, not customs or legal advice.
