Method
How we rank manufacturers
Rankings on this site compare how complete and checkable each company's information is. They are not a judgement of product quality.
Where the data comes from
Company names, products and contacts are compiled from Chinese-language public sources: company websites, published product catalogues and national business registration records. Each company is matched to its registered legal entity, and the unified social credit code is shown on its profile where available.
The completeness score
Each profile scores up to 100 points:
| Field | Points |
|---|---|
| Official website | 20 |
| Company overview (40+ words) | 15 |
| Three or more product lines | 15 |
| Province and city | 10 |
| Business registration record | 10 |
| Published email | 10 |
| Founding date | 5 |
| Published phone | 5 |
| Logo | 5 |
| Capabilities | 5 |
How a category is ordered
- Chinese manufacturers with full profiles, by score. Ties are ordered alphabetically.
- International brands with China operations, in a separate section.
- Companies whose full profiles are still being prepared, listed with their registered name and contacts.
A category ranking is published once at least 6 Chinese manufacturers in it have full profiles.
What the rank does not mean
A higher rank means more complete, checkable information. It does not certify quality, capacity or compliance. Always confirm certificates, ratings and test reports with the manufacturer before ordering.
Independence
Listings are free. No company can pay to appear or to change its position.
