Many traders and importers do not know how to apply for coal safety certification when importing electrical equipment underground in coal mines. Below, Zhongnuo Testing will provide a detailed introduction to the basic process of applying for coal safety certification for imported products.

Due to the special nature of imported products, there are two types of coal safety labeling applications:

1Apply for Coal Safety MA Mark by Batch

(1) Basic process

1) Submit materials to apply for coal safety labels to national institutions

2) National institutions assign tasks to designated laboratories

3) The laboratory sampled this batch of imported products and conducted tests according to relevant standards.

4) After passing the inspection, the batch of imported products will be inspected on site

5) After passing the inspection, the coal safety mark certificate will be issued
