What happened?
Amazon’s 2026 FBA fee changes involve several key metrics: low-inventory fees are now calculated by FNSKU rather than parent ASIN, significantly affecting sellers with multiple variations; the storage-fee threshold has moved forward from 271 days to 181 days; and return-processing fees now cover nearly all categories. These changes are intended to improve inventory turnover across the platform.
What does this mean for cross-border sellers?
Sellers should use Amazon’s Profit Analytics dashboard for detailed cost calculations and plan inventory for high-turnover SKUs to offset margin pressure from higher fees.
