Why FBA margins collapsed in 2025–2026
Four compounding cost shocks that spreadsheets and Amazon's own calculator don't capture.
Tariff whiplash: 145% peak → 10% → 12.5% forced-labor tariff
IEEPA tariffs peaked at 145% in 2025, were struck down in February 2026, and a 10% Section 122 surcharge ran until 24 July 2026, when a 12.5% forced-labor Section 301 tariff replaced it. MFN + Section 301 + 12.5% now stack on every China-sourced unit: a $10 unit on a 25% Section 301 list costs $13.75+ before a single FBA fee.
De minimis exemption eliminated
The $800 duty-free threshold ended for Chinese goods in May 2025 and for every country in August 2025. Every product in your FBA catalog is now subject to full duty, whatever its origin. Sellers who relied on small direct-to-consumer shipments lost a key cost advantage overnight.
FBA fees rising while margins shrink
Amazon's 2026 fee schedule added a 3.5% fuel and inflation surcharge on top of fulfillment fees. A large-standard item that cost $4.75 in fulfillment fees now costs an additional $0.17 per unit — and Amazon adjusts these mid-year without notice.
No single tool shows the true per-unit landed cost
Amazon's own revenue calculator shows FBA fees but ignores import duties entirely. Jungle Scout and Helium 10 estimate product revenue but don't calculate tariffs. Sellers are forced to stitch together 3–4 tools and a spreadsheet.
The FBA tariff stack — 2026
Each layer is applied on top of the previous, compounding the effective rate. This is why a 25% Section 301 product can have an effective duty rate above 60%.
| Cost layer | Rate | Note |
|---|---|---|
| MFN base duty | 0% – 37.5% | Varies by HTS code |
| Section 301 (Lists 1–4A) | 7.5% – 25% | Most FBA goods from China |
| Forced-labor Section 301 tariff | 12.5% | China since 24 Jul 2026 (replaced Section 122); computers, phones, chips exempt |
| Merchandise Processing Fee | 0.3464% | Min $34.58, max $670.86 per entry |
| Harbor Maintenance Fee | 0.125% | Sea shipments only |
| Amazon fuel & inflation surcharge | 3.5% | Applied on top of FBA fulfillment fee |

FBA tariff FAQ
Does Amazon's FBA Revenue Calculator include import duties?
No. Amazon's Revenue Calculator shows FBA fulfillment fees and referral fees only. It has no knowledge of import duties, Section 301 tariffs, the forced-labor tariff, or freight costs. You must calculate your landed cost separately before entering COGS in the Revenue Calculator.
What is the Section 301 tariff rate on FBA products from China?
Section 301 rates depend on which USTR List your product falls under. List 1 (machinery, electronics): 25%. List 2 (chemicals, metals): 25%. List 3 (general consumer goods): 25%. List 4A (consumer goods, apparel): 7.5%. Many plastic and household staples — plastic phone cases, kitchen items, fitness accessories — are on List 4A at 7.5%; pet leashes, LED lamps and many electronics accessories are on List 3 at 25%; most toys are on the suspended List 4B (0%). The 12.5% forced-labor tariff applies on top regardless of list, except for computers, phones and chips.
What happened to the $800 de minimis exemption?
The $800 duty-free exemption ended for Chinese goods on 2 May 2025 and for every country on 29 August 2025; CBP made it a regulation in June and July 2026, and Congress repeals it outright from July 2027. All shipments — regardless of value or origin — now pay full import duties. Sellers who used direct-to-consumer models (ship small to each customer) lost this exemption entirely.
How do I calculate landed cost per unit for FBA?
Landed cost per unit = (Unit FOB cost × [1 + MFN rate + Section 301 rate + forced-labor rate]) + (freight per unit) + (MPF per unit) + (HMF per unit, if ocean). The Zentria calculator does all of this automatically. You then add FBA fulfillment fee and Amazon referral fee (typically 15%) to get total cost before profit.
Should I switch from China to Vietnam sourcing?
Vietnam is the most common alternative for FBA sellers fleeing China tariffs. Vietnam pays standard MFN rates (0–37.5%) and the same 12.5% forced-labor tariff as China — but no Section 301 list rate. That makes identical products typically 7.5–25 percentage points cheaper in duty from Vietnam in 2026. Use the Zentria landed cost calculator to compare both origins side by side.
