Used Phones

Wholesale Phone Grading Without a Fake Standard

Why Grade A, B, and C are not a global phone standard, and how to write cosmetic and functional grades that two inspectors can repeat.

Direct answer

Wholesale phone grading is a written agreement about cosmetics and function. Letter grades are marketplace shorthand, not a single official scale. If the quote says Grade A, it must also say the test, the photos, the battery rule, and the lock rule.

Key takeaways

  • There is no one public A/B/C law for used phones.
  • R2v3 is a facility reuse standard, not your lot's cosmetic scale.
  • Split cosmetic grade from functional grade.
  • Keep locks and IMEI out of the cosmetic letter.
  • Attach photos of the agreed grade, not a marketing collage.

Grading is how two people agree what a used phone looks like and whether it works. It is not a brand.

Cosmetic versus functional

Axis Answers Does not answer
Cosmetic Housing, glass, paint, frame, ports Whether the radio works
Functional Calls, charge, cameras, buttons, biometrics How deep the scratches are
Identity IMEI, serial, model Beauty
Locks Carrier, account, MDM Beauty
Battery Health reading or runtime Paint

A Grade A letter that silently includes “must be unlocked” will fight with a Grade A letter that only means “light marks.” Write both axes.

A repeatable cosmetic scale

Use your own labels if you must, but define them:

Label Example meaning Photo rule
A Light marks, no cracks, no missing parts Front, back, sides, ports
B Visible wear, no glass cracks unless stated Same plus damage close-ups
C Heavy wear or stated cracks Damage mapped on a diagram

If a supplier uses AAA or “super A,” ask them to map it onto the table above. If they cannot, the grade is decoration.

Functional grade

List the tests. A useful minimum:

  • Powers on and holds a charge
  • Display and touch
  • Front and rear cameras
  • Cellular, Wi-Fi, Bluetooth
  • Microphones and speaker
  • Buttons and biometrics
  • Ports and charging accessories you will ship

Record pass, fail, or not tested. “100% working” is not a test list.

What must stay outside the letter

  • IMEI block-list status
  • Activation Lock or account lock
  • MDM
  • Battery below a stated floor
  • Unknown or unverified parts on iPhones

Those items are accept/clarify/reject fields. Mixing them into Grade B hides the expensive failures.

Accept / Clarify / Reject

Claim Accept Clarify Reject
“Grade A” Written cosmetic scale plus photo rule Letter only Letter that silently includes locks or IMEI
“100% working” Named test list with pass / fail / not tested Function claimed, no tests Failed radio sold as cosmetic Grade B
“Same as last lot” Scale attached again Verbal “you know our A” New letter with no map
Mixed carton Counts by cosmetic and functional grade “Mostly A” One letter for mixed damage
Refurbished Grade A Process plus grade Grade used as the process Apple Certified language on a third-party lot

Sample inspection record

Use one row per unit. Copy the same columns onto the QC tool.

Field Example
Lot / carton HK-14-2208-A
IMEI / serial Record both if the device shows both
Cosmetic grade B — visible frame wear, no glass cracks. Photos 3–6.
Functional grade Pass on the written list except rear camera AF fail
Locks Carrier: No SIM restrictions. Account: off. MDM: none.
Battery 86% maximum capacity
IMEI check Named service, clear
Unit decision Reject — camera fail is a function fail, not a cosmetic B

The carton decision is not an average of letters. One identity or lock Reject fails that unit. A function fail is a function fail even if the housing is Grade A.

Frequently asked questions

Is Grade A the same as refurbished?

No. Grade A is usually a cosmetic claim. Refurbished is a process claim. A Grade A used phone can be unrepaired. A refurbished phone can still show wear if the process allows it.

Can I use the seller's grade without inspecting?

Only if you accept their scale in writing and still sample it. Two sellers' Grade B can differ on scratches, battery, and function.
