Some Amazon Buy Shipping rates need extra information before the label can be bought, usually customs details for international shipments. In the rates list these rates show Requires additional inputs.
How to fill in additional inputs
Select the Amazon rate in the ship window.
A button appears for each group of inputs Amazon asks for. A yellow warning icon means the group is required, a gear icon means it is optional.
Click a button, fill in the fields and click Save. For item details, a table opens with one row per item on the order. The button turns to a green check when it is filled in.
Buy the label as usual.
Field formats
The fields and their formats come from Amazon and the carrier for that rate, so they can differ between rates. If a value does not match the expected format, the field is outlined in red with Invalid format. Common fields and the formats Amazon usually expects:
Item Description: 3 to 25 characters; letters, numbers, spaces and - . _ & only. Example: Cotton T-Shirt
Item Description (translated): the same description in the language the carrier asks for, for example Chinese.
Country of Origin: the 2-letter country code where the item was made. Example: US, CN
HS Code: up to 10 digits; spaces and hyphens are allowed. Example: 6109.10 must be entered as 610910
Item Weight: choose the unit (gram, kilogram, pound or ounce) and enter the number.
Item Value: choose the currency and enter the value per item as a number. Example: 12.50
Hazardous: check the box if the item is hazardous material.
If Amazon asks for a field not listed here, the hint under the field shows what it expects. If you still cannot buy the label, contact SKULabs support with the order number and a screenshot of the field.
