Where each UGP grade lands in the condition names of Back Market, Amazon Renewed, Swappa, eBay and Google Merchant.

Maps to, not endorsed. These are the marketplaces' own condition names. UGP maps to them; no marketplace has endorsed this mapping, and each marketplace's own listing rules still apply.

A dash means the marketplace has no matching condition for that grade. Annex D

Why the names do not line up

The same word means different things from one site to the next. "Excellent" is the top used tier on some sites and the second on others. "Good" is UGP's third used grade but another site's second. That is why UGP never borrows these words: adopters use the UGP name in the reader's language, and map to a marketplace's word only when listing there. §11.4

Listing on a marketplace

  • Use the marketplace's condition from this table for its condition field, and keep the UGP name, its test and the version in the description where the marketplace allows it. §13.3
  • Disclose a carrier lock, non-genuine parts and a partial kit as UGP requires, even where the marketplace's condition field has no place for them. §11.4
  • Acceptable has no consumer-marketplace condition in this table; it is mainly sold wholesale.
