What a QC proof pack should clarify
| Field | Why it matters | Buyer action |
|---|---|---|
| Model / storage | Confirms the quoted SKU scope | Match report examples to RFQ lines |
| Grade reference | Aligns cosmetic expectation before payment | Compare A+ / A / B rules before PI |
| Diagnostic status | Reduces DOA and functional surprise | Ask which checks are included in the proof pack |
| IMEI / serial scope | Supports traceability if a claim happens | Confirm evidence format and claim window |
QC proof checklist
- ✓ Ask for sample proof before first PI
- ✓ Confirm grade definitions in writing
- ✓ Keep RFQ, PI, and proof pack SKU names aligned
- ✓ Save IMEI / serial evidence for claim handling
QC FAQ
Do you provide QC reports for every wholesale order?
QC proof options are aligned during the RFQ stage, before any proforma invoice is issued. Buyers can request a sample proof pack for the quoted model and grade, or agreed batch-level evidence for a repeat order. A typical proof pack covers representative appearance photos, boot status, screen and touch checks, a battery reference, IMEI or serial scope, functional test notes, and packing photos. The exact scope is written into the quote so both sides know what evidence will exist before payment. For first orders, the 5-unit trial path uses the same proof format as a full batch, which lets a new buyer verify the reporting quality at low exposure before committing to weekly or monthly replenishment volumes.
Is a QC report the same as a warranty?
No, and the distinction matters for claims. A QC report is pre-shipment evidence: it records the condition, grade reference, and functional status of the batch before the proforma invoice is approved, so expectations are aligned before money moves. Warranty and DOA handling are post-delivery commitments and follow the agreed RMA terms — the standard baseline targets under 2% functional RMA within a 30-day window, measured against the delivered batch, with exclusions for misuse, impact, liquid damage, and unauthorized repair. The QC report becomes the reference document if a dispute happens: the IMEI or serial scope recorded in it is what a claim is checked against. Buyers should keep the RFQ, the PI, and the proof pack aligned on SKU naming so that evidence holds up during resolution.
What should first-time buyers check first?
Start with the four items that decide whether a batch matches your market: model and storage scope, the written grade definition (not just the letter — ask what A+ or A means in cosmetic tolerance for this supplier), the battery reference used in the report, and the diagnostic scope actually tested. Then confirm the claim process before approving the PI: what counts as a functional defect, the claim window, what evidence is required, and the resolution options (replacement, credit, or adjustment). Ask for a sample proof pack on the first RFQ — a supplier that produces one quickly with consistent SKU naming across quote and report is showing you its real process, not a promise. The 5-unit trial path exists so this whole loop can be verified once at small scale before a repeat order.
