USPS Adds 8% Fuel Surcharge on Package Shipping Starting April 26
The U.S. Postal Service announced a temporary 8% price increase on competitive package products — including Priority Mail, Priority Mail Express, USPS Ground Advantage, and Parcel Select — effective April 26, 2026 through January 17, 2027. The surcharge is driven by a 40% spike in global crude oil prices and comes on top of a 7.8% general USPS rate increase already implemented in January 2026, creating a cumulative year-over-year cost jump of nearly 16% for high-volume shippers. FBM sellers who rely on USPS for affordable ground shipping face immediate margin pressure.
Real-World Impact
A FBM seller shipping 200 packages/month via USPS Ground Advantage at an average $8.50/label currently pays $1,700/month. After the 8% surcharge, that rises to $1,836/month — an extra $136/month or ~$1,632/year in shipping costs alone.

What You Should Do Now
- 1Audit your current carrier mix in Seller Central → Reports → Shipping to see what percentage of FBM orders ships via USPS
- 2Recalculate shipping cost assumptions in your FBM profit models for all affected USPS services
- 3Compare UPS and FedEx rates — with their own fuel surcharges, USPS remains competitive but the gap has narrowed
- 4Consider adjusting FBM product pricing or adding handling fees to offset higher per-order shipping costs
- 5Evaluate whether high-volume FBM SKUs should be shifted to FBA to eliminate carrier cost volatility
