Grade B covers used smartphones and tablets with visible scratches and minor frame dents but no cracked screens. The device must be 100 percent functional, with battery health typically above 80 percent on iPhones and equivalent on Android.
Grade B is the bulk-volume tier for secondary-market retail. Most carrier trade-in programmes and refurbisher pipelines produce more Grade B stock than any other tier. Pricing typically runs 12-25 percent below Grade A for the same model and configuration.
The cosmetic threshold between Grade A and Grade B is the most negotiated boundary in wholesale electronics. Some suppliers split the difference with a “Grade A-” or “Grade A/B mix” tier, useful in pricing but a frequent source of post-shipment disputes if not pre-defined in writing.
Buyers reselling to budget retail channels, export markets (Latin America, Africa, South-East Asia), and specialised refurbishers buy Grade B in volume. Most insurance pools and trade-in returns ultimately route through this tier.
