Imported products can also apply for the Coal Safety MA mark. It is divided into two types: importer application and foreign production enterprise application.

(1) Apply for the MA logo according to the batch. To apply for the MA mark for a batch of imported products, importers only need to go through the application, sampling and testing process. After the testing is completed, there is no need to go through on-site evaluation of the production enterprise. They only need to inspect the batch of products and issue the certificate directly. But this certificate is only applicable to this batch of imported products, and it has no expiration date. The advantages are fast certification and low cost.

(2) Apply for the MA mark for domestically produced products. After a series of processes including application, sample testing, on-site evaluation, and certification. It is worth noting that on-site evaluation requires going to foreign production enterprises for evaluation, and the provided materials must be in Chinese, which is relatively expensive and time-consuming.

8. Can the same production enterprise apply for the Coal Safety MA mark only once for different product categories?

may not.

According to relevant regulations, even for the same production enterprise, different product categories must apply for the Coal Safety MA mark separately and undergo on-site evaluations separately.
