Which products should you submit the identifier_exists attribute with a value of no for?
Correct Answer
D) Custom-made clothing
Key takeaways
The exemption is for products no manufacturer ever assigned an identifier to.
Custom-made, handmade, vintage and one-off items qualify.
Used condition and pre-order status do not remove an existing identifier.
Why is this the correct answer?
The exemption is for products that genuinely have no manufacturer-assigned identifier, and custom-made clothing is the clearest case here — a one-off garment has no GTIN because no manufacturer ever assigned one. The other options all describe products that do have identifiers: bundles, used electronics and pre-order books were all manufactured as identifiable items, whatever their condition or availability.
Why are the other options wrong?
A) Items as part of a bundle
Bundles are handled with the is bundle attribute, and the components still carry manufacturer identifiers.
B) Used electronics
Used electronics were manufactured with a GTIN, which remains valid. Condition is declared separately through the condition attribute.
C) New books for pre-order
A book has an ISBN, which serves as its GTIN. Being on pre-order affects availability, not identity.
Frequently asked questions about this topic
How do I declare a used item correctly?
Keep the genuine GTIN and set the condition attribute to used. Accurate condition is a policy requirement, and declaring a used item as new can escalate from item disapproval to account-level action.
