中国海关在《中华人民共和国进口食品境外生产企业注册管理规定》(248号令）中有明确规定：

第十九条　在注册有效期内，进口食品境外生产企业注册信息发生变化的，应当通过注册申请途径，向海关总署提交变更申请，并提交以下材料：

（一）注册事项变更信息对照表；

（二）与变更信息有关的证明材料。

海关总署评估后认为可以变更的，予以变更。

生产场所迁址、法定代表人变更或者所在国家（地区）授予的注册编号改变的应当重新申请注册，在华注册编号自动失效。

There are clear regulations in "Regulations of the People's Republic of China on the Registration and Administration of Overseas Manufacturers of Imported Food"(GACC Order 248)：

Article 19 If an overseas manufacturer’s registration information changes while the registration is valid, it shall submit an application for change to the GACC through the application path, and submit the following materials:

1. A table that exhibits the changed information and the original information;
2. Supporting materials related to the changed information. The GACC changes the registration information if it deems such information can be changed after review. In cases of changing production site, legal representative, or registration number in the country/region where the manufacturer is located, the overseas manufacturer shall re-apply for registration, and the original Chinese registration number will automatically become invalid.
