Amazon.com Inc. announced Dec. 20 that it will cancel some long-term storage fees for third-party sellers on units housed at Amazon fulfillment centers.

From Jan. 15, 2019, third-party items held for 181 to 365 days will not carry a charge. Additionally, Amazon will reduce the minimum storage fee on units placed for over 365 days to 15 cents per unit from 50 cents.

The e-commerce giant will introduce separate monthly storage fees for items that contain flammable or pressurized aerosol substances from April 2019. Monthly inventory storage fees for other products will remain unchanged.

Amazon is also making changes to its fulfillment fees. From Feb. 19, 2019, a separate fulfillment fee structure for dangerous goods will be introduced, and there will be increases in fulfillment fees for products other than small standard-size and large standard-size items, for which the rates will remain unchanged.

Additionally, Amazon decreased referral fees for third-party sellers.

Overall, the company expects fees for over 40% of fulfilled-by-Amazon units to either remain unchanged or decrease.
