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). Canada 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.
Canada is generally a favorable origin for US importers because most goods that meet USMCA rules of origin can enter the United States duty-free. Qualifying Canadian goods are also generally treated more favorably than goods from origins targeted by broad import surcharges, so when a product qualifies the duty line on your landed cost is often zero rather than a stacked add-on. That can make Canadian sourcing simpler to model than China-style origins, where a base duty plus additional trade actions can compound. The important caveat is that duty-free treatment is conditional: it depends on the product actually qualifying under the rules of origin, certain sectors (steel, aluminum, autos, and softwood lumber are recurring examples) can still carry their own duties or trade actions regardless of USMCA, and trade actions and surcharges can change. Confirm the duty outcome for your specific product, since the exact rate depends on its HS classification. This is general guidance, not customs or legal advice.
For many categories, Canada can be a margin-stable alternative to China rather than a like-for-like swap that just relocates the problem. When a good qualifies under USMCA, the duty line is typically zero, which can remove one of the more volatile inputs in your landed-cost math relative to origins exposed to broad surcharges. The honest catch is twofold. First, duty-free is not automatic: you generally have to confirm the product meets the rules of origin and keep supporting documentation, such as a USMCA certification of origin, available, because content made elsewhere and merely finished in Canada may not qualify. Second, Canada's input cost base is often higher than low-cost Asian sourcing, so the unit price before duty can be more expensive even when the tariff is zero, and a handful of sectors (steel, aluminum, autos, lumber) can carry their own duties that USMCA does not erase. Net it out per SKU on a landed-cost basis: Canada often wins on tariff certainty and lead time, but verify origin qualification and compare the all-in delivered cost, not just the headline duty rate, and remember the exact rate depends on your product's HS code. 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.
Paste your Shopify URL. In about ten seconds you'll see every SKU that dropped below your target margin after the current Canada tariffs — and the exact price to charge to recover each one. Free, no login.

For a $30 pair of sunglasses from Canada at a 0% stacked rate, that means charging $17.50 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.
Do goods from Canada really enter the US duty-free?
Often, yes, but only when the product qualifies under USMCA's rules of origin. USMCA generally allows qualifying goods to cross duty-free, but qualification depends on where the materials and production actually originate, not just the country you ship from. Goods that contain significant non-North-American content, or that are only lightly processed in Canada, may not qualify and could be dutiable. Treat duty-free as conditional and confirm each product's eligibility rather than assuming it applies catalog-wide. This is general guidance, not customs or legal advice.
What do I need to claim USMCA duty-free treatment on a Canadian import?
You generally need to establish that the good meets the applicable rule of origin and have a USMCA certification of origin available to support the claim. The certification can generally be completed by the importer, exporter, or producer, and you should keep the supporting records on file in case US Customs asks you to substantiate it. Because qualifying for any trade program depends on rules of origin, work with your supplier and a customs broker to confirm the specific rule for your product's classification before you rely on a zero duty rate in your pricing. This is general guidance, not customs or legal advice.
Is moving sourcing from China to Canada a safe way to avoid tariffs?
It can meaningfully reduce tariff exposure, but it is not a guaranteed zero-duty fix and it carries its own load. The potential benefit is real: USMCA-qualifying Canadian goods can avoid duties and surcharges that may apply to goods from other origins. The catch is that Canadian unit costs are often higher to begin with, certain sectors such as steel, aluminum, autos, and softwood lumber can still face their own duties, and the duty-free benefit only holds if the product genuinely qualifies under the rules of origin. The specifics depend on your product's exact HS code and on current trade actions, which can change. Compare the full landed cost per SKU, including verified origin status, before treating the switch as a margin win. This is general guidance, not customs or legal advice.
