How to Choose an OEM Tumbler Supplier in China: 10-Point Checklist

China hosts thousands of drinkware factories. For B2B buyers, the challenge is finding one that survives audit, delivers consistent lids, and scales from sample to repeat order. Use this 10-point checklist during factory evaluation.

The 10 Points

1. Food-contact documentation — LFGB/FDA reports tied to your model
2. Social audit status — BSCI, WCA, or SQP for retail onboarding
3. In-house vs outsourced decoration — laser, UV, heat transfer, sublimation
4. Mold ownership clarity — get it in writing
5. Sample lead time — realistic timelines, not vague promises
6. MOQ transparency — confirm per SKU and decoration type
7. Lid compatibility testing — leak tests should be standard
8. Capacity realism — ask for evidence of production scale
9. Export references — EU/US shipment history signals maturity
10. Communication protocol — single export contact, English spec sheets
