Grade A in wholesale electronics describes a used smartphone or tablet that exhibits only minor micro-scratches on the screen or housing, with no chips, dents, or cracks. The device must be 100 percent functional including all sensors, cameras, speakers, microphones, and biometric components.
For iPhones, battery health must be 85 percent or above (visible in Settings > Battery > Battery Health). For Android, the equivalent threshold is typically 85-90 percent of design capacity. All parts must be original (no aftermarket screens, batteries, or back glass), and the device must be free of iCloud Activation Lock, FRP (Factory Reset Protection), MDM enrolment, and carrier locks.
Grade A is the highest-margin tier in used wholesale and the closest substitute for new retail. Most carrier-insurance and manufacturer trade-in programmes route their cleanest stock into the Grade A pool. Buyers reselling into consumer-refurbished channels (Back Market, Swappa, Amazon Renewed) typically require Grade A or higher.
The single biggest dispute pattern in Grade A trading is grading drift, one trader's Grade A is another's Grade B. Always specify thresholds in writing on the purchase order.
