How can a Hong Kong company and Hainan company work together for foreign trade collection?

Short Answer

A Hong Kong company and a Hainan company can work together for foreign trade or cross-border e-commerce, but their roles in contracts, platform accounts, collection, procurement, invoices, customs and tax should be clearly divided.

Who This Applies To

• Business owners across China planning to use a Hainan entity for real business, tax compliance or group planning.
• Foreign investors, overseas companies, trading teams and cross-border e-commerce operators evaluating Hainan Free Trade Port opportunities.
• High-profit companies, group companies and founders preparing tax planning, equity structure, financing or pre-IPO compliance.

Key Points to Review

• Whether the Hong Kong company collects overseas payments, signs contracts or holds platform accounts.
• Whether the Hainan company handles procurement, export, services, settlement or domestic tax matters.
• Whether transfer pricing, service fees or trade margins need explanation.
• Whether platform records, bank flow, invoices and accounting entries are consistent.

Practical Path

• Map the role of each entity in the transaction chain.
• Design contracts and fund flow between Hong Kong, Hainan and customers/suppliers.
• Prepare accounting and tax treatment for each entity.
• Maintain documents for bank, tax and later financing review.

Common Risk

If Hong Kong and Hainan roles are mixed randomly, overseas collection, tax filing and accounting explanations can become difficult.
