The coal safety certification application process includes preliminary document review and submission, product testing, and on-site assessment.
The review of materials focuses on the timeliness and completeness of the information prepared and provided by the company, while the product testing phase considers the specific structure, complexity, and testing projects of the product.
On-site review stage is also crucial; if an on-site review is conducted, evidence can be collected directly. If issues arise during the audit process, continuous rectification and re-audits are required, which also increases the cycle. The normal process for coal safety certification is approximately 4-6 months.

Currently, the frequent occurrence of coal safety certification is under the safety standardization center. Under the safety standardization center, there are various testing institutions across different regions, each responsible for testing products in specific fields. Generally, companies applying for coal safety certification cannot directly find a laboratory to conduct testing; they must go through the safety standardization center's designated testing and certification laboratories. In fact, the domestic coal safety certification system is still quite strict. It combines type testing with factory production system reviews to ensure that the applicant company has the capability to ensure product production and quality. Even after obtaining the coal safety certification, companies must still undergo annual supervision and evaluation by the safety standardization center.
