Section 301 tariffs on China-origin goods entered a new phase in 2026 after the staged increases that started in late 2024 fully phased in. For FBA sellers who built their unit economics around the lower 2023 tariff schedule, the cumulative impact this year is no longer theoretical — it shows up on every entry summary. Here is how we are seeing sellers reset, based on shipments we have moved through Long Beach and Newark over the past quarter.
Where the new rates bite hardest
The categories with the steepest cumulative climb since 2024 are predictable but worth restating because many sellers still underestimate them: lithium-ion battery products, EVs and components, semiconductors, certain solar inputs, syringes and PPE, and a wider sweep of steel and aluminum derivatives. For FBA sellers, the practical pain falls on three buckets we see every week:
- Consumer electronics accessories with batteries — wireless earbuds, power banks, smart trackers. Lithium-ion components push the effective duty meaningfully higher than the BOM suggests.
- Home goods and small appliances with steel or aluminum content — racks, frames, kitchen tools — that get caught by the broader derivative coverage.
- Health and wellness gear — TENS units, blood pressure monitors, certain massage devices — where component classification meaningfully changes the rate.
The three resets we are recommending
1. Re-run your HTS classification with a customs broker, not your forwarder. The single highest-leverage move this year is to challenge HTS codes that were assigned years ago. Subheading differences of a single digit can change the Section 301 list a product falls into, and CBP rulings published in 2025 opened legitimate reclassification paths for several common SKUs. Your forwarder will not do this for you; a licensed broker will.
2. Look at first sale valuation if you import through a middleman. If your goods pass through a Hong Kong, Vietnam, or Mexico trading company before reaching the US, first sale valuation can lower the dutiable value to the original factory price. It requires clean documentation back to the factory and a contract structure most sellers do not currently have — but the savings on a high-velocity SKU pay for the legal work in one or two cycles.
3. Stop overbuying inventory to “beat tariffs.” Several of our 2024 clients front-loaded six months of inventory ahead of the 2025 increases. By Q3 last year they were paying Amazon long-term storage fees that wiped out the tariff savings. The math rarely works once you factor in capital cost plus FBA storage. Order on a tighter cadence and use bonded warehousing if you genuinely need to defer duty.
What is still working: country-of-origin diversification
Sellers who began moving final assembly to Vietnam, Malaysia, or Mexico in 2023-2024 are seeing real tariff relief in 2026 — provided they can substantiate substantial transformation and meet origin documentation requirements. CBP has tightened audits on Vietnam-routed China-origin goods, so the paperwork bar is higher than it used to be. We are seeing the best results from sellers who do final assembly, packaging, and quality control in the new country rather than just trans-shipment.
What to do this week
Pull your last 90 days of CBP Form 7501 entries and calculate your blended effective tariff rate per SKU. If any single SKU has crossed 35% cumulative duty plus Section 301, that SKU needs an action plan before your next PO. If you want help running this exercise against your shipment history, contact our team — we will share the same SKU-level tariff exposure template we use with our active accounts.
