Short answer: Look for the 3C / CCC mark on the power bank body or printed regulatory label, not only on a box, listing, or receipt. For China domestic flights, a missing, worn, or unclear mark can still create airport-screening risk, especially if the exact model or recall status cannot be confirmed.
The practical airport check starts with the object in your hand. Search the power bank body, underside, back label, side panel, or printed regulatory block for the 3C / CCC mark and model information.
Do not rely only on the retail box or online listing if the mark is not visible on the device. CAAC screening focuses on what passengers carry, and unclear 3C marks can be treated as a problem for mainland China domestic flights.
The 2026 CCC traceability-QR pilot adds more product-marking context for newly certified pilot products, but a traveler should still keep the physical device evidence readable and confirm the exact model and recall status before flying.
Rule summary
- Best place to check
- Power bank body, underside, back label, side edge, or regulatory text block.
- Weak evidence
- Box, receipt, marketplace listing, or photo alone may not satisfy airport screening.
- Unclear mark
- A worn or unreadable 3C / CCC mark can create the same practical risk as no mark.
- Next check
- Match the exact model, Wh / mAh label, recall status, and trip rule.

The final answer can change by model, airline, country, certification mark, label evidence, and recall status.

Can the 3C mark be on the box only?
Do not rely on box-only evidence for airport screening. The safer travel assumption is that the device body should show readable 3C / CCC evidence.
What if the 3C mark is scratched or faded?
For mainland China domestic flights, an unclear mark is a real risk because CAAC explicitly includes unclear 3C marks in the prohibited-screening scope.
Does a CCC QR code mean I can ignore the printed mark?
No. The traceability QR pilot is product-certification context. Travelers should still keep the device label readable and run an exact-model trip check.
