5 Documents required for dispute
A summary of carton contents with the weight of each individual item, proving the total carton weight is less than 50 lbs [1]
Proof that the carton contained one sellable unit[1]

1 Definition≠ Differs from North America
An overweight carton occurs when you send a box to a fulfilment centre containing more than one sellable unit that weighs over 23 kg, unless the sellable unit itself is heavier than 23 kg. [2]
2 What triggers it & how to prevent it Final composition for this type
✕ What triggers it
A box with multiple sellable units exceeds 23 kg[2]
Heavy carton without warning label — a carton weighing more than 15 kg but less than 23 kg was shipped without warning labels[2]
For heavier cartons, ship one sellable unit per carton with warning labels in a highly-visible location [1][2]
Apply heavy warning labels to all cartons over 15 kg — a large, coloured label (red "caution heavy") on four sides, without covering carton or pallet labels (SSCC / AMZNCC / GTIN) [2]
Apply warning labels even when cartons are palletised, since pallets are decanted at inbound receiving [2]
Applies to hardlines, softlines, consumables (excluding Beer, Wines and Spirits), books and entertainment media; does not apply to Amazon Fresh, Advantage or Vendor Flex [2]
4 Official exemptions≠ Differs from North America
Cartons over the weight limit are permitted if they contain only one sellable unit, with proper warning labels affixed in a highly-visible location[1][2]
If the sellable unit itself weighs more than 23 kg, the carton is exempt [2]
Any single item over 31.5 kg should be routed automatically to a designated FC equipped for heavy items — ensure the ASIN weight is correct in the catalogue so this happens automatically [2]

A summary of box contents with each item's weight proving compliance — state the ASINs in the charged box[2]
Pictures of the box showing it contained just one unit and that a warning label was placed on four sides (only applicable if one ASIN was shipped in one box) [2]
Pictures of how the box is usually shipped — the inside with the ASINs, the outside showing box details (if applicable), and the box on a scale showing its weight [2]
