Why Are My Tariffs So High?

What Is Section 301?

Section 301 refers to a provision of the Trade Act of 1974 that gives the U.S. Trade Representative (USTR) authority to impose tariffs on imports from countries found to engage in "unfair trade practices." Starting in 2018, the Trump administration used Section 301 to impose sweeping additional tariffs on imports from China, citing intellectual property theft and forced technology transfer.

These tariffs were added on top of existing base duty rates — they don't replace them. If your product had a 5% base duty rate and Section 301 adds 25%, your effective rate is now 30%.

The Four Lists

Section 301 tariffs were imposed in four tranches — commonly called Lists 1 through 4. Each list covers different HTS chapters and carries a different rate:

List	Effective Date	Rate	Coverage
List 1	July 6, 2018	25%	Industrial goods, aerospace, machinery — ~$34B in trade
List 2	Aug 23, 2018	25%	Chemicals, plastics, electronic components — ~$16B
List 3	Sept 24, 2018	25%	Consumer goods, apparel, food products — ~$200B
List 4A	Sept 1, 2019	7.5%	Consumer electronics, footwear, apparel — ~$120B

Lists 1, 2, and 3 carry a 25% additional duty. List 4A carries 7.5%. The Biden administration kept all of these in place and the Trump administration's second term has layered additional IEEPA tariffs on top — meaning many China-origin goods now face effective rates of 50% or higher when all overlays are combined.

Who Actually Pays The Tariff?

The tariff is assessed at the time of U.S. customs entry and paid by the importer of record — the U.S. company or individual whose name appears on the customs entry. Not the Chinese factory. Not your freight forwarder. You.

Many importers are surprised to learn this. If your supplier quotes you a CIF or DAP price that "includes all tariffs," that money is still ultimately coming from your gross margin. The tariff is collected by CBP at the border as a percentage of the declared value of your goods.

Were There Exclusions?

Yes — the USTR ran exclusion processes that allowed companies to apply for product-specific exclusions from Section 301 tariffs. If granted, the exclusion allowed an importer to enter goods at the base duty rate without the 301 overlay.

Most exclusions have expired. Some were renewed; many were not. If you previously operated under a product exclusion, you need to verify its current status. CBP will not remind you — they'll just assess the duty.

What Are Your Options?

• Tariff engineering: Modify the product before import so it classifies under a different, lower-duty HTS code. Must be a real physical change — not just relabeling.
• Country of origin shift: Move manufacturing to a non-301 country (Vietnam, India, Mexico). Requires genuine manufacturing, not just transshipment.
• Valuation reduction: Even if you can't avoid the tariff, you can often reduce the dutiable value through §1401a deductions and the First Sale Rule — meaning you pay the rate on a lower base.
• Protest filing: If you've been assessed 301 tariffs incorrectly (wrong HTS, wrong country of origin determination, expired exclusion being applied), you can protest within 180 days of liquidation.
• First Sale Rule: If goods pass through an intermediary, declaring the factory price instead of the middleman price reduces your dutiable value by 15–25% on average.

How To Check Your Exposure

1. Pull your last 10 CBP entries — your broker can provide the CF 7501s. Look at column "A" for HTS codes.
2. Cross-reference against the Section 301 lists — the USTR publishes the full HTS lists at ustr.gov. Any code on those lists from a China-origin shipment is hit.
3. Calculate total 301 duty paid — multiply entered value × 301 rate for each entry. Sum across all entries.
4. Identify reducible value — look for embedded freight (if CIF/DAP terms), buying commissions, and U.S. IP fees in your invoices. These are deductible.
5. Get a licensed broker review — HTS codes and valuation are both areas where broker errors are common and consequential.
