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.
Goods from Taiwan generally enter the US under standard most-favored-nation (Column 1) duty treatment, so the base rate is set by each product's HS code rather than by any China-style punitive surcharge. Taiwan may carry some limited additional load on top of the base duty, but it is not subject to the China-specific Section 301 stack, which tends to keep landed cost more predictable than for Chinese-origin goods. For Shopify merchants this matters because the duty you pay tracks your classification, not a separate Section 301 list. The rate box on this page is a representative working figure tied to MFN duty plus any limited additional load that applies, not a guaranteed per-SKU rate. None of this is customs or legal advice, and your exact per-SKU duty still depends on how your product is classified under its specific HS code.
For many categories Taiwan can be a margin-friendlier alternative to China: there is no China-specific Section 301 layer, the base duty is the MFN rate for your HS code, and Taiwan is an established manufacturing base, particularly for electronics, semiconductors, and precision components, so quality and supplier reliability are often not the bottleneck. The catch is that "no China surcharge" does not mean "low cost." Taiwan still carries the MFN base duty plus whatever limited additional load applies, its labor and input costs typically run higher than lower-wage Southeast Asian hubs, and capacity for high-end manufacturing can come at a premium. There is also no comprehensive US-Taiwan free trade agreement, so you should not assume duty-free entry the way an FTA partner might offer, and qualifying for any reduced-duty program would depend on rules of origin you would need to verify against your actual bill of materials. Treat Taiwan as a de-risking option for electronics and precision goods rather than the cheapest possible origin, and run the landed-cost math per SKU, against your exact HS code, before shifting volume.
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.

Scan your store free →Landed cost = unit cost × (1 + tariff rate). To get back to a target margin M, the recovery price is landed cost ÷ (1 − M). For a $90 part from Taiwan 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 sourcing from Taiwan avoid the China Section 301 tariffs?
Generally yes for the China-specific layer. Section 301 tariffs apply to products of China, so Taiwanese-origin goods are typically not subject to that particular stacked surcharge. You would still pay the standard MFN base duty for your product's HS code plus any limited additional load that applies, so Taiwan is usually lower-duty than China but not duty-free. Origin is determined by where the product is substantially transformed, not just final assembly, so verify your supply chain actually qualifies as Taiwanese before assuming the China rate disappears. Confirm your specific HS classification, since that is what sets the rate.
Is there a US-Taiwan free trade agreement that makes imports duty-free?
No comprehensive US-Taiwan free trade agreement is in force, so you should not assume duty-free entry. Some narrower bilateral trade arrangements have been discussed or pursued, but none functions as a broad tariff-elimination FTA the way agreements with some other partners do. Your duty is the MFN rate for your classification plus any additional load that applies, and qualifying for any reduced-duty program would depend on specific rules of origin. Treat the rate box on this page as a working number and confirm your exact HS classification before committing volume.
Is Taiwan a good origin for electronics specifically?
Often, yes. Taiwan is a major electronics and semiconductor manufacturing hub with established capability in chips, components, and precision assembly, so for many electronics categories it can offer solid quality and supplier reliability without the China-specific Section 301 layer. The trade-off is cost: high-end Taiwanese manufacturing often prices above lower-wage Southeast Asian alternatives, and you still owe the MFN base duty for your HS code. Run the per-SKU landed-cost math, because the right answer depends on your specific product, its exact HS classification, and your target margin rather than the country alone.
