Grade A, B, or C? What Phone Grading Actually Means on a 30-Unit Order

Two suppliers quote you Grade A on the same model, $40 apart. One of them is not lying. They are using different rubrics, because there is no enforced global grading standard for used phones. Every trader and refurbisher publishes their own.

If you buy in 30-unit lots, that gap is the single biggest source of surprise in your cost per unit. Here's how to read a grade properly.

No global standard exists, and that's the whole problem

There are real certifications in this industry. R2v3, RIOS and ADISA all certify how a refurbisher operates: data security, environmental handling, downstream accountability, worker safety. What none of them do is standardise what a scratch on a screen is called.

So a certified facility and an uncertified one can both sell you "Grade A" and mean different things by it. The certification tells you the seller runs a serious operation. The grade letter, on its own, tells you almost nothing until you see their written spec.

What Grade A usually means in trade usage

Across most wholesale rubrics in circulation right now, Grade A means light micro-scratches on the screen and frame, no chips, no marks visible on the display when it's powered on, fully functional, and battery health above 85%.

Notice the last item. Battery is quietly baked into a cosmetic-sounding letter, which is exactly why two Grade A quotes can differ by real money. If the seller's rubric puts the battery floor at 80% instead of 85%, that's a different product wearing the same name.

Grade B and Grade C: where the margin lives

Grade B typically allows visible scratches and minor dents on the frame, but no cracked glass. Grade C allows real cosmetic damage: chips, dents, heavy scratches, still functional.

For a lot of Caribbean and Latin American resellers, Grade B is the sweet spot. The buyer wants a working phone at a price they can afford, and a scuff on the frame doesn't close the sale. Grade C works when you have a repair bench, or when you're feeding a market that shops purely on price. Grade C without a repair capability tends to turn into returns.

Battery health: pick your number before you buy

The common floor on major refurbished marketplaces is 80%. The working wholesale norm sits higher, around 85%. Buyers feeding stricter retail channels often insist on 90% or better.

For context on what those numbers mean physically: Apple designs iPhone 14 and earlier batteries to retain 80% of original capacity at 500 complete charge cycles under ideal conditions, and its battery and performance guidance explains where the Battery Health screen lives and when a Service message appears. A unit sitting at 81% is technically inside most rubrics and close to the point where the end user starts noticing.

Decide your floor before you negotiate price. Otherwise you'll negotiate on the letter and inherit the battery.

IMEI status is a separate check from grade

A pristine Grade A handset that's flagged as lost or stolen is worth nothing to your customer. The GSMA maintains a block list of IMEIs that operators have reported, and its Device Check service returns a clear green or red status per IMEI. The Device Check FAQ explains who can access it and what each status means.

Ask for the IMEI list before the pallet ships, not after. It also gives you the serial-level record you'll want if a national registry, like Peru's, asks for one at import.

The four lines your spec sheet needs

• Cosmetic definition in plain words, with the maximum defect allowed at that grade.

• Minimum battery health as a number, not a word.

• Functional test scope: screen, cameras, speakers, mics, charging port, Face ID or fingerprint.

• IMEI status and regional variant, confirmed per unit before shipping.

If a supplier can't produce those four lines in writing, the price you were quoted isn't really a price. It's a guess.

Before your next order

Grading isn't a mystery. It's just undocumented more often than it should be. Once you fix your own spec and hold suppliers to it, the letter on the invoice starts meaning something again, and your returns rate follows.
