Auto parts are among the goods most exposed in the current tariff era, because a large share of the catalog is sourced from China and the parts that carry the most trade-remedy exposure are often the high-turnover ones merchants reorder constantly. The base duty on a chapter 87 part is generally modest, but it does not always arrive alone, and add-on rates can, depending on origin, turn a thin reseller margin negative on a single replenishment. If you sell brake pads, filters, sensors, or trim sourced overseas, the landed cost you priced against earlier may differ from what you pay today, so it is worth re-checking before you reorder.
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.
Sri Lanka is a long-established apparel and textile supplier to the United States, and like most trading partners it now sits in the current reciprocal-tariff era, which layers a country-level load on top of each product's base HTS duty. It does not have a US free-trade agreement, so there is generally no zero-duty shortcut on most goods, and its exports are among those that carry a reciprocal-era load. For landed cost, that means the duty on a Sri Lankan shipment is the stacked total of the product's base rate plus the prevailing reciprocal load, not the base rate alone. The exact number depends on the precise HS classification, so treat the rate box as a directional figure rather than a quote.
Sri Lanka is a workable alternative to China for apparel and soft goods, with a long track record in higher-end knitwear, intimates, and technical garments and a reputation for compliance-focused factories that larger buyers often look for. But it is not a margin-free escape hatch: it carries its own reciprocal-era load, so the question is always whether Sri Lanka's stacked rate beats your China stacked rate for your specific HS codes, not whether it is duty-free. The catches are practical as well as fiscal: capacity is concentrated in apparel, so non-textile categories have a thinner supplier base, lead times and freight from South Asia tend to run longer than from Vietnam or Mexico, and minimums at the larger factories can be high for a small Shopify catalog. Run the per-SKU landed-cost comparison before committing, because a lower base duty can be offset by the reciprocal load. Whether any preferential treatment applies would turn on the specific program and its rules of origin, which you would need to confirm for your own goods; 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 Sri Lanka tariffs — and the exact price to charge to recover each one. Free, no login.

For a $90 part from Sri Lanka at a 37.5% stacked rate, that means charging $113.44 to hold a 40% margin. Round to a clean price point and test it; the point is to stop selling underwater.
The duty starts with where the part lands in the Harmonized Tariff Schedule, and many finished vehicle parts fall under chapter 87 (parts and accessories of motor vehicles). The chapter alone does not set your rate: components are often classified by what they are made of or what they do rather than by the car they go on, so an electrical sensor can pull into chapter 85, a rubber hose into chapter 40, a fastener or bracket into chapter 73, and a bearing into chapter 84. What tends to move the rate is the part's primary function and material, whether it is a general-purpose article versus a part 'solely or principally' for a vehicle, and the country of origin, since origin is what can determine whether Section 301 China duties or other trade-remedy measures apply on top of the base rate. Those measures change over time, so confirm what is currently in force. The exact figure is per-SKU and depends on the precise HS code, so treat any single number as a starting point, not a quote.
A common trap is the 'parts' versus 'general-purpose article' line. A bolt, spring, gasket, or bearing you think of as an auto part is frequently classified by its own nature in chapters 73, 40, or 84 rather than as a chapter 87 vehicle part, which can land it at a different base rate and a different trade-remedy exposure than the rest of your catalog. The mirror-image trap is assuming everything that bolts to a car gets chapter 87 treatment, when an item with an independent commercial identity (a battery, a stereo, a standard bulb) is often classified by its function elsewhere. Pull the actual HS code your customs broker is filing rather than inheriting whatever the overseas supplier wrote on the commercial invoice, since their classification may be geared to export paperwork rather than to what you owe at US entry.
Because much of the auto-parts exposure is origin-driven rather than baseline-duty-driven, a high-leverage move can be shifting sourcing away from the origin that triggers the stacked rate, rather than chasing a lower base rate. Many parts have credible alternate-origin supply in countries such as Mexico, Taiwan, Vietnam, or Thailand, and for goods that qualify under USMCA rules of origin, Mexican-made parts may sit outside the China-specific layers. Substantial transformation is generally the standard that matters here, so simply trans-shipping a finished Chinese part through a third country does not change its origin and can be treated as evasion. This is a customs-compliance question to confirm with your broker before you act. Before you switch, confirm the new supplier's part carries the same HS code and price the full landed cost including the new origin's duty treatment, since a 'cheaper' factory can still cost more once its own classification and freight are included.
Why is my auto-parts duty higher than the roughly 2.5% base rate I expected?
The chapter 87 base rate is generally only the floor. For parts of Chinese origin, Section 301 duties and other trade-remedy measures may apply on top of it, which can produce a landed cost above the headline number; the specifics depend on the measures currently in force. Your effective rate is therefore driven largely by country of origin, not by the base classification alone, so two otherwise identical parts from different countries can carry very different total duty even when they share the same HS code. Confirm the current rate for your specific SKU.
Do I owe the same duty on a sensor or wiring harness as on a brake rotor?
Often no. Electrical components like sensors, harnesses, and control modules are frequently classified in chapter 85 rather than as chapter 87 vehicle parts, and they can carry a different base rate and different trade-remedy exposure. Mechanical parts like rotors, calipers, and suspension arms tend to stay in chapter 87 or pull into chapter 84. The reliable way to know is to check the specific HS code per SKU rather than applying one blanket rate across your catalog.
Can I avoid the China tariff by having the parts shipped through another country first?
Generally no. Routing a finished Chinese part through a third country to relabel its origin is trans-shipment, and US customs can treat it as evasion rather than a legitimate origin change. To actually change origin, the standard is usually substantial transformation, meaning the part is genuinely manufactured or substantially worked on in the new country. Real alternate-origin suppliers or USMCA-qualifying production are legitimate paths, paperwork rerouting is not, and the specifics are worth confirming with a customs broker.
Does the US have a free-trade agreement with Sri Lanka that lowers duties?
No. There is no US-Sri Lanka free-trade agreement, so most goods do not get a preferential or zero rate the way they might from an FTA partner. Sri Lankan imports generally pay the product's base HTS duty plus the prevailing reciprocal-era load. Any duty relief would hinge on a specific program and its rules of origin, which you would need to verify for your goods rather than assume. This is general guidance, not customs or legal advice.
Is Sri Lanka actually cheaper than China once tariffs are stacked?
Sometimes, but you cannot assume it. Sri Lanka carries its own reciprocal-era load, so the only honest answer comes from comparing the full stacked rate (base duty plus country load) for your exact HS codes against your China figure. Depending on the codes, the comparison can favor either origin, and a lower base rate can be offset by the reciprocal load, so check the landed cost per SKU before shifting orders. This is general guidance, not customs or legal advice.
What categories is Sri Lanka realistically good for sourcing?
Its strongest fit is apparel and textiles, especially knitwear, intimates, swimwear, and technical or performance garments, where it has mature, compliance-focused factories. Outside soft goods the supplier base is thinner, so for electronics, hard goods, or furniture you will usually find more depth in Vietnam, India, or China. Match the country to the category, and confirm a factory can meet your volume, since minimums at the larger plants can be high for a small catalog. This is general guidance, not customs or legal advice.
