According to the latest standards officially released by Amazon, starting in 2022, the long-term storage fees for standard-size inventory and oversized inventory will be adjusted. The long-term storage fee for standard-size inventory will be charged at $0.75 per cubic foot, while the long-term storage fee for oversized inventory will be charged at $58.46 per item. In addition, Amazon will also charge monthly storage fees and other fees based on the weight and size of the product. Therefore, sellers need to pay attention to Amazon's notifications in a timely manner and arrange inventory reasonably to avoid unnecessary additional costs.
