How to say a device is graded to UGP: the version, the conformance level and the verification tier, every time.

The claim

A party that grades to UGP states three things: the version, the conformance level and the verification tier.

Graded to UGP v1.0 · UGP-Full · V0 Declared

A letter or a name alone, without the version, is not a conformant claim. §13.4

While v1.0 is a public comment draft, records graded to it cite it as UGP v1.0 (public comment draft). Spec status

Conformance levels

LevelWhat was recordedWhat you can show
UGP-FullEvery applicable axis, the core code and an audit trailThe grade, with its disclosures
UGP-CosmeticThe cosmetic axis only; other axes can be unknownThe cosmetic value only, never a grade
UGP-FunctionalFunctional, locks and data; cosmetic can be NThe functional, lock and data results; with cosmetic N the status is Not graded

§13.1

Verification tiers

TierNameWhat backs the record
V0DeclaredThe grader or seller supplies the record and answers for it
V1EvidencedV0, plus the profile's photo set, a diagnostic report and a lost/stolen check (not a declaration), all within 72 hours of the offer
V2InspectedThe unit, or a lot sample, inspected by the steward or an inspector the steward approved

§13.2 · §14.2

V2 on its own is not "UGP Verified": that name is reserved for V2 units inspected under the steward's certification programme, which is not open yet. §13.5

Examples

A cosmetic-only intake reportUGP v1.0 · UGP-Cosmetic · V0 Declared · cosmetic value B
A supplier's stock, mapped through a published crosswalkGraded to UGP v1.0 · UGP-Full · V0 Declared · supplier-mapped

A supplier-mapped grade, transcribed from a supplier's own scale through a published crosswalk, is always V0 Declared and is labelled supplier-mapped in records and exports. §13.6

Where the claim goes

Every offer and every document of sale records the version the unit was graded under, and a dispute is judged against that version. A later version never reinterprets an old record, though the unit can be regraded from its stored raw data and re-issued. §14.6

The “Graded to UGP” mark carries the same claim in a badge.
