Importing from China to the United States has become significantly more complex and expensive since 2018. Layered on top of the standard Most Favored Nation (MFN) duty rates in the Harmonized Tariff Schedule (HTS), US importers now face multiple additional tariff programs: Section 301 tariffs targeting Chinese goods specifically, Section 232 tariffs on steel and aluminum, and evolving de minimis rules that affect low-value shipments. Understanding this layered tariff structure is essential for any business importing from China in 2026.
Section 301 tariffs were imposed in four tranches (Lists 1-4) beginning in 2018, covering approximately $370 billion worth of Chinese imports. As of 2026, these tariffs remain in effect and have been expanded in several product categories following the 2024 review. Current rates range from 7.5% to 100% depending on the product category, with the most significant increases applied to electric vehicles (100%), semiconductors (50%), solar cells (50%), steel and aluminum products (25%), batteries and battery components (25%), and critical minerals (25%).
Some products have received temporary exclusions from Section 301 tariffs. Check the USTR Federal Register notices for current exclusions. Exclusions are product-specific (by HTS code) and time-limited. Camtom automatically flags 301 tariff applicability and current exclusions during classification.
Section 232 tariffs apply a 25% additional duty on steel imports and a 10% additional duty on aluminum imports from most countries, including China. These tariffs stack on top of both the MFN duty rate and any applicable Section 301 tariffs. For Chinese steel products, the effective tariff can exceed 50% when combining MFN duty + Section 301 + Section 232. Derivative steel and aluminum products (downstream articles like nails, wire, cans) are also covered under expanded 232 provisions.
The de minimis threshold allows goods valued at $800 or less to enter the US duty-free and with simplified customs procedures. This provision, under Section 321 of the Tariff Act, has been increasingly scrutinized as e-commerce platforms like Temu and Shein ship millions of low-value packages directly from China. In 2024-2025, CBP implemented stricter enforcement including requiring more detailed product descriptions, HTS codes for de minimis shipments, and proposed legislation to exclude China-origin goods from de minimis eligibility entirely. Importers relying on de minimis for China-origin goods should monitor these changes closely.
A $10,000 FOB shipment of consumer electronics (List 4A) with 2.6% MFN duty + 7.5% Section 301 = 10.1% total duty = $1,010. Add freight ($800), insurance ($50), MPF ($35), and broker fees ($200) = $12,095 landed cost. That same product before Section 301 would have been $11,095 — a 9% increase in total cost.
The China-US tariff environment is the most complex in global trade today. Getting your HTS classification right is the single most impactful thing you can do — it determines your MFN rate, 301 applicability, and regulatory requirements. Camtom's AI-powered classification tool helps you navigate this complexity by automatically identifying all applicable tariffs and fees for your products.
