Legal analysis: the procedures of equity transfer can be changed without industrial and commercial changes, and the registration of equity transfer change is not an effective requirement of the equity transfer contract, and the failure of the parties to go through the registration procedures does not affect the effectiveness of the equity transfer contract. Where a limited liability company changes its shareholders, it shall apply for registration of change within 30 days from the date of change, and submit the qualification certificate of the new shareholder or the identity certificate of a natural person.

Legal basis: Provisional Regulations of People's Republic of China (PRC) Municipality on the Administration of Tax Collection.
