Item package weight and dimensions refers to the weight and dimensions of the individual unit that you’re listing under a FNSKU. The weight and dimensions include the unit’s packaging, such as the individual box or poly bag. The item, item package, and case can all have distinct weight and dimensions. FBA fees are based on item package weight and dimensions.
In the illustration below, the duck is the standalone item. The duck in a box is the item package and the four ducks in boxes comprise a case.
Amazon uses a variety of sensors instrumented throughout fulfilment centres to capture item measurements. The measurement sensors will capture your item packaging from edge to edge, including loose material, such as plastic bags, or loose parts, such as handles.
To replicate potential machine measurements, take a single item package with the item inside, as it would be received by a customer. On a flat surface, fully extend loose packaging material, such as poly bag flaps and package handles, to capture the maximum item package dimensions. Measure the item package’s longest edge as its length, its second longest edge as its width, and its shortest edge as its height.
If one or more of these dimensions is varies across the package, due to a bulge in the packaging or something similar, measure the longest or thickest part of that dimension. To minimize the dimensions of deformable packaging, ensure that the packaging doesn’t exhibit loose material by using methods such as tight-fitting or vacuum-sealed poly bags, or taped flaps.
Fees that use item package weight and dimensions in their calculations include FBA fulfilment fees, monthly storage fees, long-term storage fees, FBA inventory storage overage fees, FBA removal order fees, FBA disposal order fees, fulfilment fees for Multi-Channel Fulfilment orders, FBA Inventory Placement Service fees, and FBA Prep Service fees.
Yes, the measurement sensors that capture dimensions in our fulfilment centres will evaluate packaging from edge to edge, including loose poly bag and protruding handles. To minimize the dimensions of deformable packaging, ensure that the packaging does not exhibit loose material by using methods such as tight-fitting or vacuum-sealed poly bags, or taped flaps, so that the dimensions of the same item packages are as similar to each other as possible.
Fees for FBA services, such as fulfilment fees and storage fees, are based on item package weight and dimensions. If you believe that the item package weight or dimensions associated with your FNSKU are incorrect, you can submit a request for a remeasurement. We will locate a unit belonging to your inventory and remeasure it in one of our fulfilment centres. Your FNSKU’s updated weight and dimensions will apply across all marketplaces within the region where we received your request.
The following packaging practices minimize size tier discrepancies:
When possible, avoid the following items and packaging types, which cause the most common discrepancies:
You can request a remeasurement through the Remeasure FBA products and confirm fees widget. Locate the widget by typing “remeasure” into the search bar.
Yes, effective 29 September, 2021, monthly request limits will be set at the account level. Limits per account allows us to respond faster to all requests.
Effective 29 September, 2021, your remeasurement limit will be displayed under the Remeasure FBA products and confirm fees widget. Locate the widget by typing “remeasure” into the search bar. The limit is based on the number of offers with inventory in your account. As you submit requests, we’ll subtract from this limit. On the first of each month, we’ll reset your account’s request count back to zero.
Only submit requests that you believe will result in a change to your fees. When you submit too many remeasurement requests that don’t result in fee changes, we may not be able to process requests that are affecting fees in a timely manner.
You may submit those requests the following month. However, in a given month, if we detect that a high percentage of your remeasurement requests are resulting in changes to your fees, we’ll increase your account’s request limit to ensure that we’re able to provide the assistance that you need. In this case, you’ll see a message to proceed with submitting your request.
Other reasons we may not be able to process remeasurement requests include the following:
