Cross-border co-branding refers to the form of joint promotion and cooperation between companies in different industries. Relevant policies for cross-border co-branding include:

1 Product Safety Supervision and Management Measures: It is stipulated that products produced by cross-border co-branding must be approved by the General Administration of Quality Supervision, Inspection and Quarantine before they can be sold on the market.

2 Trademark Law: It is stipulated that trademarks used jointly across borders must be approved by the industrial and commercial administration department and obtain a trademark registration certificate.

3 Anti-Unfair Competition Law: It is stipulated that cross-border joint branding shall not harm the legitimate rights and interests of consumers, and shall not use false publicity or fraudulent sales methods.

4 Advertising Law: It is stipulated that cross-border joint advertising must be true and legal, and must not be deceptive or misleading.

Cross-border co-branding is an effective marketing tool, but it also needs to comply with relevant laws and regulations to protect the rights and interests of consumers.
