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.
Brazil ships to the United States under standard Most-Favored-Nation (MFN) duty rates as a WTO member, and there is no comprehensive US-Brazil free trade agreement that zeroes out tariffs the way USMCA does for Mexico. On top of the baseline MFN duty, current-era trade measures can add further load, so the effective rate a Shopify merchant pays may sit above the column-one number alone. Brazil also no longer has a duty-free path through the US GSP program while that program remains lapsed, so importers that historically relied on it cannot assume it today. The practical takeaway is that you should price landed cost from the combined duty stack rather than the headline MFN rate, because any add-on loads can move the real number. The exact figure depends on your product's HTS classification, so treat the rate box on this page as a representative starting point, not your final number.
Brazil is a genuine manufacturing base in several categories (footwear, leather, furniture, processed foods, certain industrial and agricultural goods), and for merchants diversifying away from China it can reduce supply-chain concentration risk. But it is not an automatic margin-safe escape hatch: without an FTA and with GSP lapsed, you generally pay MFN plus whatever current-era loads apply to your category, so the duty side may not be meaningfully cheaper than alternatives once everything is stacked. The honest framing is that Brazil's appeal is diversification and category fit, not a guaranteed tariff discount. The catch is twofold: the combined duty load can erode unit-cost savings, and longer ocean transit plus currency (BRL) swings add landed-cost volatility. Run the math per HTS code on the all-in landed cost before committing, and treat any duty advantage as something to verify, not assume.
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 $90 part from Brazil 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 Brazil that lowers tariffs?
No. There is no comprehensive US-Brazil free trade agreement, so goods generally enter at standard MFN duty rates rather than the duty-free or reduced rates available under deals like USMCA. Brazil also does not currently benefit from the US GSP program, which previously gave some products duty-free treatment but has lapsed. Plan your landed cost around MFN duty plus any current-era loads that apply to your category, and confirm the specifics for your HTS code.
How do I figure out the actual tariff on what I'm importing from Brazil?
The duty depends on your product's HTS classification, and the all-in rate combines the MFN base duty for that code with any current-era add-on measures in effect. The rate box on this page shows a representative figure, but your real number can differ once your specific classification and any extra measures are applied. Confirm the exact HTS code for your product and verify the current stacked rate before you price, since this is general guidance and not customs or legal advice.
Could a product from Brazil still qualify for reduced or preferential duty?
Possibly, but it depends on the specific program and on rules of origin, not just the country of shipment. A good has to genuinely originate in Brazil under the applicable origin rules, and simple transshipment or light finishing usually will not qualify it. Because GSP has lapsed and there is no broad FTA, most goods default to MFN treatment, so treat any preferential claim as something to confirm with a licensed customs broker rather than assume.
