📘 The Ultimate Yuan Wang Digital Mall Sourcing Guide

🏢 Market Structure: Floor by Floor

• 1st Floor (Lobby & Accessories): AirPods, Apple Watch, precision repair tools, and logistics services (parcel shipping, packaging).
• 2nd & 3rd Floors (The Mobile Core): iPhones, iPads, Samsung devices. Shops organized by brand and "Grade" (A, B, C).
• 4th Floor (Spare Parts & Screens): OLED screens, high‑capacity batteries, original cameras, back glass panels. Paradise for repair technicians.

🔬 Verification Protocol (Quality Check)

Never pay without testing. Use this rigorous protocol:

• 📱 3uTools Test: Connect iPhone to a PC running 3uTools. Verify all components (Battery, Screen, Cameras) show "Normal".
• 👤 Face ID / Touch ID: Test systematically. A defective Face ID reduces value by 40% and is very difficult to repair.
• 🖥️ Screen Verification: Check for white spots or dead pixels against a white background. Test True Tone to confirm original vs. reprogrammed screen.
• 🔓 iCloud / MDM Lock: Ensure device is "Clean" and ready for worldwide activation.

🔍 Advanced Inspection (Back‑office)

• Water Seal Integrity: Examine the SIM tray slot – look for red moisture indicators.
• Screw & Housing Alignment: Original screws are pentalobe and flush. Misaligned screws indicate previous repair.
• Microscope Check: For high‑value units, inspect logic board for signs of rework or corrosion.

🏷️ Decoding the "Price Tags" (Labels)

Handwritten slips contain critical info:

• Seller Code: Shop name or WeChat ID at the top.
• Capacity & Model: e.g., "15PM-256-B" = iPhone 15 Pro Max, 256GB, Grade B.
• Price Ticker: "52" = 5,200 CNY. Prices update daily at 2:00 PM.

🔄 The Secret of "Swap Units"

Many phones at Yuan Wang are brand‑new replacement units issued by Apple during warranty service. They have model numbers starting with "N" (not "M") and often zero battery cycles – highly sought after.

💰 Negotiation & Pricing

• Wholesale vs. Retail: Prices on tags are for batches of 5‑10 units. Single unit adds 50‑100 CNY.
• "Market Price" Fluctuation: Prices reset at 2:00 PM daily. Avoid finalizing too early.
• Warranty: Standard 7‑day warranty (indicated by a small stamp on the bottom screw). If stamp is broken, warranty is void.

📦 Logistics & Shipping

• Packaging: Use vacuum‑sealing and reinforced bubble wrap services on the ground floor.
• Customs Declaration: For large shipments, use dedicated lanes (France/Canada Special Line) that handle lithium batteries compliantly.
• Insurance: Never skip shipping insurance for high‑value items (iPhone 15 Pro Max, etc.).
