Summary
Who this is for: US importers who source goods from China and want a clear explanation of Section 301 tariffs, what changed in 2024 and 2025, and what options they have for managing the cost.
Key takeaways:
- Section 301 tariffs were originally imposed in 2018-2019 and applied rates of 7.5% to 25% on hundreds of billions of dollars of Chinese goods.
- 2024 and 2025 brought significant new rounds of increases, with some categories including EVs, solar cells, and steel products seeing rates jump to 50% or more.
- The tariffs work by adding a percentage to the dutiable value of your goods at the time of customs entry. That cost lands on the US importer, not the Chinese exporter.
- Strategies for managing tariff exposure include HTS classification review, first sale valuation, supplier diversification, bonded warehouses, and formal exclusion requests.
- Getting your HTS code wrong under a tariff environment is not just an accuracy issue. It’s a financial and legal one.
What’s inside:
- What Section 301 actually is and where it comes from
- How the tariff rates are structured (the four lists and current rates)
- What changed in 2024 and 2025
- How the tariff calculation works in practice
- Legitimate strategies for reducing your tariff exposure
- What importers are getting wrong about tariff compliance
If you import anything from China, you’ve been living with Section 301 tariffs since 2018. But the environment has changed significantly in the past two years, and what worked as a cost-management strategy in 2022 may not be holding up anymore.
This is not a political analysis of whether the tariffs are good policy. This is a practical explanation of what they are, how they work, what changed recently, and what options US importers actually have for managing the exposure.
What Is Section 301?
Section 301 refers to a provision of the Trade Act of 1974 that gives the US Trade Representative (USTR) authority to investigate and respond to foreign trade practices that are deemed unfair or discriminatory. The authority allows the US government to impose tariffs on goods from a specific country in response to those practices, without going through standard WTO dispute resolution processes.
In 2018, the Trump administration used Section 301 authority to impose tariffs on Chinese goods following a USTR investigation that concluded China was engaged in unfair technology transfer and intellectual property practices. Those tariffs were implemented in four phases, referred to as List 1 through List 4.
The Biden administration kept the tariffs in place and added to them in 2024. The Trump administration in 2025 escalated further. The result is a layered tariff structure that now affects an enormous range of goods across nearly every product category.
The Four Lists: What Gets Taxed and at What Rate
The original Section 301 tariff structure was organized into four lists based on the timing of implementation and the category of goods affected. Here’s how it breaks down at a high level:
List 1 (July 2018): 25% tariff
Applied to approximately $34 billion in Chinese goods. This list hit industrial machinery, aircraft parts, medical devices, and certain agricultural products. Products that the USTR determined had the most direct connection to the technology transfer concerns at the heart of the investigation.
List 2 (August 2018): 25% tariff
An additional $16 billion in goods. Semiconductors, electronic components, plastics, chemicals, and certain steel products were included here.
List 3 (September 2018, later modified): rates vary
This was the big one. Initially set at 10%, then raised to 25% in May 2019. It covered approximately $200 billion in goods, including a massive range of consumer and industrial products: furniture, apparel, electronics, auto parts, machinery, and much more.
List 4 (September 2019, partial implementation): 7.5% to 25%
The originally announced List 4 was split into 4A and 4B. List 4A went into effect at 7.5% in February 2020 after the Phase One trade deal was reached. List 4B was never implemented. The 7.5% rate on List 4A goods remains in place.
What Changed in 2024 and 2025
The Biden administration’s 2024 review resulted in targeted but significant rate increases on specific product categories. Electric vehicles from China went to 100%. Lithium-ion batteries climbed to 25%. Solar cells reached 50%. Steel and aluminum products under Section 301 saw increases to 25%.
The 2025 tariff environment accelerated this further. The Trump administration reimposed and expanded tariffs across a broader range of goods, including categories that had previously been at lower rates. Some electronics and consumer goods categories that were at 7.5% moved higher. Certain industrial goods saw rates shift again.
The practical reality for importers is that the tariff rate you budgeted with in 2023 may not be the rate applying to your 2025 shipments. If you haven’t reviewed your HTS classification and corresponding tariff rates recently, this is worth doing before your next order.
How Section 301 Tariffs Actually Work at the Border
Understanding the mechanics matters because the calculation isn’t always straightforward.
When your ocean shipment arrives at a US port and your customs broker files the entry, CBP assesses the applicable tariffs based on the HTS classification of your goods and the country of origin. For Chinese-origin goods subject to Section 301, the tariff adds a percentage on top of the normal MFN duty rate.
Example: You import steel shelving units from a factory in Guangdong. The HTS classification puts them under a List 3 product category at 25% Section 301 + the standard 2.9% MFN duty rate. Your CIF value (cost, insurance, freight) for the shipment is $100,000. Your total duty bill is approximately $27,900, before any other fees. That’s real money on every single shipment.
The tariff is assessed on the importer of record. Your Chinese supplier does not pay it. You do, at the point of US entry. Any supplier who told you the tariff is their problem or offered to “handle it” is either mistaken or trying to obscure the true cost in their pricing.
Country of Origin Matters More Than Ever
Section 301 tariffs only apply to goods originating in China. But “originating in China” has a specific legal meaning under US trade law, and it’s not simply where the goods shipped from.
Substantial transformation is the core test. If a product is manufactured in China and then undergoes minimal processing in Vietnam before being exported to the US, it may still be considered Chinese-origin for tariff purposes. CBP has been scrutinizing this aggressively, particularly for products in categories where China-origin tariffs are high.
Transshipment, which is routing Chinese goods through a third country to avoid tariffs without meaningful transformation, is customs fraud. Companies that do this intentionally face civil and criminal penalties that make the tariff itself look small. If a supplier pitches you on a country-of-origin scheme that sounds too convenient, that’s a serious red flag.
Genuine supplier diversification (actually manufacturing in Vietnam, Mexico, India, or other countries) is a legitimate strategy. It requires real supply chain changes, not just a different stamp on the box.
Strategies for Managing Section 301 Tariff Exposure
There is no magic solution. But there are legitimate approaches that reduce exposure without creating compliance risk.
HTS classification review
The most common (and most underused) tariff reduction strategy is making sure your goods are classified correctly. Different HTS codes within the same product family can carry different tariff rates. Misclassification that results in overpaying duties is surprisingly common. A licensed customs broker can review your current classifications and identify whether you’re paying more than you legally owe.
First sale valuation
Customs duties are normally calculated on the transaction value of your purchase from the Chinese seller. But if you’re buying through a trading company or agent and there was an earlier sale from the factory to the intermediary, US law allows you to use that lower first-sale price as the dutiable value. For importers buying through trading companies, this can meaningfully reduce the tariff base.
Bonded warehouses and FTZs
Goods stored in a CBP-bonded warehouse or a Foreign Trade Zone (FTZ) do not have duties assessed until they exit the bonded status and enter US commerce. For importers who redistribute goods internationally or need flexibility in timing their duty payments, this can be a useful tool. It delays the cost, though it doesn’t eliminate it.
Section 301 exclusion requests
The USTR periodically opens exclusion request processes that allow importers and industry groups to petition for specific product exclusions from the tariff lists. Exclusions are granted on a product-specific basis, not company-specific, and they have historically been time-limited. The exclusion process requires documentation that the product isn’t available from non-Chinese sources and that the tariff creates significant economic harm.
Supply chain diversification
For importers with the volume to justify it, moving production or sourcing to Vietnam, India, Mexico, or other countries outside China is the most permanent solution. This takes time, investment, and strong supplier relationships. Beyond Logix’s strategic sourcing team helps importers model total landed cost across different sourcing scenarios before committing to a supply chain shift.
What Importers Are Getting Wrong
A few mistakes show up consistently in conversations with importers who are getting hit harder than they should be.
Relying on old classification decisions. HTS classifications are not permanent. Products change. The tariff lists change. A classification that was correct in 2019 may not reflect the current rate structure. Review annually at minimum, and whenever you add new products.
Treating tariff cost as fixed. The strategies above are real. Importers who treat the tariff as a fixed pass-through cost without exploring classification, valuation, or sourcing options are leaving money on the table.
Underestimating the paper trail. CBP audits tariff declarations. If your claimed country of origin is wrong, if your first sale documentation doesn’t support the valuation, or if your classification doesn’t match the physical goods, you’re exposed. The documentation has to support the declaration.
Ignoring the downstream cost. Tariff increases get passed through supply chains. If you’re a manufacturer importing components, your finished goods cost goes up. If your competitors are sourcing from non-tariffed countries, your price disadvantage compounds. This is a strategic issue, not just a compliance one.
The Tariff Environment in 2025
As of mid-2025, Section 301 tariffs remain in place and are actively enforced. The political environment suggests continued pressure on China trade, regardless of which administration is in office, given bipartisan support for some form of trade restrictions on Chinese goods.
What that means for importers is that this is not a temporary problem to wait out. The tariffs that went into effect in 2018 are still there seven years later. Planning your import strategy around tariff removal is not a prudent approach.
What is prudent: working with a licensed customs broker who tracks tariff list updates, exclusion opportunities, and classification changes on your behalf. The customs brokerage team at Beyond Logix monitors these changes as part of standard service. If a new exclusion opens for a product category relevant to your imports, you’ll know about it.
Frequently Asked Questions About Section 301 Tariffs
What is Section 301 and why does it exist?
Section 301 is a provision of the Trade Act of 1974 that gives the US Trade Representative authority to impose trade restrictions on countries engaged in unfair trade practices. The current Section 301 tariffs on Chinese goods were implemented starting in 2018 in response to a USTR investigation into China’s intellectual property and technology transfer practices.
Which Chinese goods are subject to Section 301 tariffs?
The tariffs apply to products organized into four lists (List 1 through List 4), covering hundreds of product categories and hundreds of billions of dollars in trade value. The lists include industrial machinery, electronics, chemicals, consumer goods, auto parts, furniture, apparel, and more. To know whether your specific product is covered, you need its HTS classification and a check against the current USTR tariff list.
What are the current Section 301 tariff rates?
Rates vary by product list. List 1, 2, and 3 goods are generally at 25%. List 4A goods are at 7.5%. Certain product categories received additional increases in 2024, including electric vehicles (100%), solar cells (50%), and lithium-ion batteries (25%). The exact rate for your product depends on its HTS classification and which list it falls under.
Who pays Section 301 tariffs?
The US importer of record pays Section 301 tariffs at the time of customs entry. The tariff is assessed on the dutiable value of the goods. Your Chinese supplier does not pay it. If a supplier claims they will “handle” the tariff or include it in their pricing as a pass-through, clarify exactly what you’re being charged and how.
Can I get an exclusion from Section 301 tariffs?
Yes, through the USTR exclusion request process, but exclusions are product-specific, time-limited, and not guaranteed. Exclusion requests require documentation that the product is not available from non-Chinese sources and that the tariff causes significant economic harm. The USTR periodically opens comment periods for exclusion requests. A licensed customs broker can help evaluate whether your products qualify.
How do I know which tariff rate applies to my product?
The tariff rate is determined by the 10-digit HTS classification of your product. Once you have the correct HTS code, you can cross-reference it against the USTR Section 301 tariff lists. A licensed customs broker handles this as a standard part of import compliance. Given the complexity of the tariff lists, this is not something to rely on manual lookup for.
Are Section 301 tariffs permanent?
There is no current sunset date. The tariffs were imposed under executive authority and remain in effect until modified or revoked. Both the Biden and Trump administrations maintained and expanded them, suggesting bipartisan political support for some form of ongoing restrictions. Importers should plan their supply chains around tariffs continuing rather than expecting removal.
Can I avoid Section 301 tariffs by shipping from Vietnam or Mexico?
Only if the goods genuinely originate in those countries. Goods must undergo substantial transformation in the non-Chinese country to qualify for a different country-of-origin designation. Simply routing Chinese goods through a third country without real manufacturing activity is transshipment, which is customs fraud with serious civil and criminal penalties. Genuine supply chain diversification to other manufacturing countries is a legitimate strategy.
How do tariffs affect my total landed cost?
Total landed cost includes the product cost, ocean freight, insurance, customs duties (including Section 301), and any other fees to get goods to your US warehouse. For importers buying from China, the Section 301 tariff is now often the single largest variable in that calculation. Beyond Logix’s strategic sourcing team models total landed cost across different sourcing scenarios to help importers make informed decisions.
What should I do if I’m not sure my tariff classification is correct?
Talk to a licensed customs broker. Incorrect classification can mean overpaying duties (which is recoverable through protest or drawback) or underpaying duties (which exposes you to CBP penalties and back-duty assessments). Beyond Logix’s customs brokerage team reviews HTS classifications as part of onboarding new clients and monitors for classification changes that affect existing accounts.
