Ask ten refurbishers what “Grade B” means and you’ll get ten slightly different answers. Device grading is one of the most important — and most inconsistently applied — concepts in the secondary electronics market. Grades drive pricing, set buyer expectations, and determine which marketplaces a unit can be sold into. Yet the letters themselves are not governed by any single universal standard.
This guide lays out what the common grades generally mean, how grading actually works behind the scenes, and why the consistency of a grading system matters far more than the letter printed on the box.
Across most of the industry, grading combines two separate assessments: cosmetic condition (how the device looks) and functional condition (how it works). The letter grade is usually a cosmetic descriptor applied after the device has passed functional testing. Here is a practical, widely recognized breakdown.
| Grade | Cosmetic Condition | Typical Use |
|---|---|---|
| Grade A | Excellent — minimal to no visible wear, no deep scratches, screen clean under inspection light. | Premium resale, “like new” listings |
| Grade B | Good — light, visible wear such as minor scratches or micro-scuffs; no cracks, fully intact. | Mainstream refurbished channels |
| Grade C | Fair — heavier cosmetic wear, deeper scratches, possible dents; cosmetically obvious but functional. | Value tier, budget buyers |
| Grade D / Salvage | Significant damage or non-functional; valued for parts or repair. | Parts harvesting, repair stock |
Note the word “generally.” Some graders split Grade A into A and A+, others fold salvage into Grade C, and marketplaces like Amazon Renewed and eBay Refurbished overlay their own condition language on top. The letters are a shared vocabulary, not a legal standard.
A flawless-looking phone with a swollen battery or a failing microphone is not Grade A — it’s a return waiting to happen. Serious refurbishment separates cosmetic from functional grading and tests both. A proper functional pass typically covers:
Cosmetics sell the unit. Functional testing is what stops it from coming back. A grading system that skimps on the second one is a liability dressed up as a bargain.
Here is the insight that experienced buyers internalize: a “Grade B” from a disciplined refurbisher who grades the same way every single time is worth more than a “Grade A” from a shop whose grading drifts batch to batch. Consistency is what lets you price confidently, forecast returns, and set accurate listings at scale.
When grading is consistent and documented, you can map a supplier’s grades directly onto your own channels and know what you’re getting before the pallet arrives. When it isn’t, every shipment becomes a re-inspection project, and your return rate becomes a guessing game.
If a partner can answer all five clearly, their grades will mean something to you. Grading isn’t about a letter on a label — it’s about a repeatable process you can trust enough to build a business on.
