Seller Flex fulfillment fees are based on the weight and dimensions of the packaged item – known as the product size tier.
A standard-size item is one that, when fully packaged, 12 kg or less and does not exceed:
Any item exceeding these dimensions is considered oversize.
To determine the correct tier for your item, find the row in the table below with measurements that do not exceed the weight or the dimensions of your item.
Use the larger of either the single unit weight or the dimensional weight. The dimensional weight is equal to the unit volume (length x width x height) divided by 5,000.
|Product size tier||Weight||Longest side||Median side||Shortest side|
|Standard size||< 12 kg||<= 45 cm||<= 34 cm||<= 26 cm|
|Oversize*||< 30 kg||> 45 cm||> 34 cm||> 26 cm|
*All items weighing more than 12 kg are classified as oversize
