According to Amazon's latest announcement, in 2025 the US station FBA fees will remain stable, and even some of the fees have been reduced,

giving sellers a ray of hope. Most importantly, the inbound configuration service fee for large items will be reduced, with an average reduction of $0.58 per item.

This change is undoubtedly a big plus for cross-border sellers who sell large items.
In addition, Amazon also announced that it will not raise sales commissions and logistics fees on the U.S. site in 2025,

and will not add new types of fees. This initiative not only helps sellers reduce cost pressure, but also provides more space for sellers to optimize inventory, marketing and selection strategies.
