For any hardware company with China-based manufacturing or sourcing, understanding the current rate schedule and your strategic options is a core part of product cost management.

List 1 (25%) covers $34 billion in goods including industrial machinery and some electronics components. List 2 (25%) covers a further $16 billion. List 3 (25%) is the broadest, covering $200 billion in goods and capturing most consumer electronics components. List 4A (7.5%) was introduced in the Phase One trade deal and covers a range of consumer goods. Most PCBs, semiconductors, and electronic subassemblies fall under List 3 at 25% on top of normal MFN duty rates. ### 2024 tariff increases — new rates on batteries, semiconductors, and strategic goods Following USTR's four-year review, the Biden administration announced significant rate increases in May 2024. Electric vehicle batteries and lithium-ion batteries (non-EV) face rates rising to 25% by 2026. Solar cells increase to 50%. Certain semiconductors increase to 50% by 2025. Ship-to-shore cranes and medical products also face increases. These rate changes phase in over 2024–2026 and are separate from — and stack on top of — existing List rates, making it essential to track the current applicable rate for your specific HTS code rather than relying on the initial list rate. ### Exclusion process — product-specific relief from USTR USTR has issued multiple rounds of product-specific exclusions that temporarily suspend Section 301 tariffs for defined products described by their HTS code and a written product description. Many exclusions have expired and required re-application. The exclusion process is highly technical — product descriptions must match your goods precisely — and exclusions can lapse without automatic renewal. Companies dependent on exclusions must monitor the USTR portal actively and file for renewal or new exclusions well in advance of expiry. ### Country of origin — substantial transformation and third-country manufacturing Section 301 tariffs apply based on country of origin as determined by US Customs and Border Protection (CBP) rules. For most manufactured goods, country of origin is where the product last underwent a 'substantial transformation' — a change in tariff classification or a meaningful manufacturing process that creates a new and distinct article of commerce. Moving final assembly to Vietnam, Mexico, or India may remove Section 301 exposure if CBP would agree that a substantial transformation occurred there, but this is a fact-specific analysis that requires a CBP ruling letter for certainty. ## How to manage Section 301 exposure for your electronics product 01 Identify your product's 10-digit HTS code using the US International Trade Commission's HTS search tool, then check it against the Section 301 list appendices published by USTR — the appendices are the authoritative source for which codes are subject to additional duties and at what rate. 02 Check the USTR exclusion database for any active exclusion applicable to your HTS code and product description — exclusions are narrowly written and must match your goods precisely; if an expired exclusion covered your product, assess whether to file for reinstatement under current USTR process. 03 Assess country of origin for your product — if components are manufactured in China but final assembly occurs in a third country, engage a licensed customs attorney or customs broker to conduct a country of origin analysis, and consider requesting a binding CBP ruling letter to provide certainty before committing to a manufacturing location change. 04 Model total landed cost with Section 301 tariffs included alongside normal MFN duty, any applicable ADD/CVD orders, MPF, and HMF — compare this against alternative sourcing scenarios from Vietnam (GSP-eligible categories), India (US-India trade dynamics), or Mexico (USMCA zero-duty potential for qualifying goods). 05 File for first sale valuation through your customs broker if you purchase goods through a middleman — first sale allows duty to be assessed on the manufacturer's price rather than the intermediary's price, reducing the dutiable value; monitor CBP ruling letters for similar HTS codes to anticipate classification disputes before they arise at the border. ## Frequently asked questions ### Which electronics products face the highest Section 301 tariff rates? Following the 2024 USTR review, the highest Section 301 rates now apply to electric vehicle batteries (100% by 2024), solar cells (50% by 2024), non-EV lithium-ion batteries (25% by 2026), and certain semiconductors (50% by 2025). For mainstream electronics components — PCBs, connectors, passives, discrete semiconductors — the applicable rate is generally 25% under List 3. Some lower-value consumer electronics on List 4A face 7.5%, though this distinction requires careful HTS classification to confirm. ### Can I avoid Section 301 tariffs by assembling in Vietnam? Potentially, but not automatically. If your product undergoes a substantial transformation in Vietnam — a change in HTS tariff classification heading at the four-digit level, or a manufacturing process that creates a new and distinct article of commerce — CBP would assign Vietnam as the country of origin, and Section 301 tariffs would not apply. However, CBP actively scrutinises country of origin claims for electronics assembled in third countries from predominantly Chinese components. Shipping Chinese subassemblies to Vietnam for final screwdriver assembly is unlikely to qualify as substantial transformation. A formal CBP ruling letter is the only way to obtain binding certainty before investing in a new manufacturing location. ### What is the current status of the USTR exclusion process? USTR periodically opens exclusion request processes for specific Section 301 lists. Many exclusions granted in 2019–2021 have expired, and reinstatement requires a new filing. As of 2024–2025, USTR has been processing exclusion requests primarily for List 3 and List 4A goods under its targeted exclusion process. Companies should monitor the USTR Section 301 portal for open comment and exclusion windows, as the process is not continuous — it opens and closes based on USTR's review schedule and Congressional direction. ### How do Section 301 tariffs interact with normal MFN duty rates? Section 301 tariffs are applied in addition to — not instead of — the normal Most Favoured Nation (MFN) duty rate that applies to all imports of that HTS code regardless of origin. The total duty payable is MFN rate plus Section 301 rate plus any applicable anti-dumping (ADD) or countervailing duties (CVD). For example, a PCB with a 0% MFN rate subject to a 25% Section 301 tariff pays 25% total; the same board with a 5% MFN rate would pay 30% total. Both ADD/CVD and Section 301 tariffs are assessed on the transaction value of the goods including assists. **Disclaimer:** Educational resource only.
