Our Quality Grading Standard: Transparency You Can Trust
We understand that consistency is the biggest challenge when importing used iPhones. As a direct wholesale supplier in Shenzhen, we eliminate the guesswork. We do not use confusing terms. Instead, we strictly adhere to a standardized, international cosmetic grading system combined with rigorous software diagnostics.
When you order Grade A, you receive exactly Grade A. No surprises. No blind boxes.
Cosmetic Grading Definitions
🌟 Grade A+ (Pristine / Like New)
The ultimate premium choice. These devices look practically brand new and are indistinguishable from a newly opened phone.
- Screen & Housing: Flawless condition. Zero visible scratches, scuffs, or dents on the glass or aluminum/stainless steel frame.
- Battery Health: 95% – 100% (Original Battery).
- Best For: High-end retail storefronts demanding absolute perfection.
✅ Grade A (Excellent)
Our most popular tier. It offers an excellent balance between premium cosmetic condition and wholesale value.
- Screen & Housing: Excellent condition. May have 1 or 2 incredibly minor micro-scratches on the housing that are completely invisible at arm’s length. The screen is essentially flawless.
- Battery Health: ≥ 90%.
- Best For: Mainstream retail stores and premium online resellers.
💰 Grade B (Good)
The highest ROI (Return on Investment) choice for volume sellers. These devices show signs of normal daily use but are fully functional.
- Screen & Housing: Good condition. Noticeable light scratches or minor scuffs on the frame or screen. However, these cosmetic imperfections can be easily and fully covered once a screen protector and a phone case are applied. No deep dents or cracks.
- Battery Health: ≥ 85%.
- Best For: Emerging markets, budget-conscious consumers, and high-volume e-commerce platforms.
Beyond Cosmetics: Our 100% Functional Guarantee
🟢 Layer 1: Software Verification (100% Green 3uTools Report)
We do not rely on manual checks alone. Every iPhone undergoes a deep system diagnostic using 3uTools, the industry standard for Apple device verification.
- We guarantee all critical components (Motherboard, Screen, Cameras, Face ID) match our stringent grading standards.
- Proof Before Shipping: We can provide an “All-Green” diagnostic screenshot or video for your specific batch before it leaves our warehouse. No hidden motherboard repairs.
🛡️ Layer 2: Physical Assurance (Tamper-Evident QC Seal)
After passing our 50-point functional test, each device receives our proprietary Tamper-Evident Security Seal.
- This seal is your ultimate quality guarantee and secures your RMA (Return Merchandise Authorization) rights.
- It ensures the device has not been swapped, opened, or tampered with by any middlemen or customs agents during international transit. If the seal is intact, your investment is fully protected by our replacement policy.
