AB+ Grade Standard

The industry-standard mid-tier cosmetic grade. Fully functional devices with minimal visible wear — the highest-volume grade in global B2B wholesale markets.

AB+ Definition: Positioned between Grade A and Grade B, AB+ (Standard) devices are 100% functional with only faint cosmetic wear. Hairline micro-scratches may be visible under strong angled light but are unnoticeable in normal use. No cracks, no dents, no deep scratches, no structural damage. The go-to grade for volume buyers seeking quality at scale.

Frequently Asked Questions


Is AB+ the most popular grade in B2B wholesale?

Yes. AB+ Standard consistently moves the highest volumes in cross-border B2B markets because it delivers cosmetically presentable stock at competitive price points. It suits retail counters, distributors, and refurb factories equally.

Can an AB+ device have a replacement screen or battery?

OEM (original manufacturer) screen and battery replacements are permitted at AB+ grade. Aftermarket or third-party non-OEM displays are a downgrade trigger and are not acceptable.

What is the difference between AB+ and Grade B?

Grade B devices show clearly visible wear in normal face-on lighting — multiple scratches and scuffs noticeable from a standard viewing distance. AB+ devices look clean at arm’s length; only careful close inspection under good light reveals faint traces of use.
