What is DGMS Approval?


The Directorate General of Mines Safety, short DGMS, is a regulatory agency under the Ministry of labour and employment of the Government of India. It´s main task is to ensure the occupational safety, health and welfare of persons employed in the Indian mining industry (coal, metalliferous and oil mines). DGMS is responsible for issuing and enforcing the relevant regulations for the Indian mining sector, such as the Mines Act of 1952 as well as all rules and regulations it includes. The DGMS is responsible for the DGMS certification of mining equipment.

Which Products are Subject to DGMS Approval?

Most equipment, machinery, appliances and/or materials intended to be used in the Indian mining sector need to undergo the approval procedure of DGMS. The authority categorizes such products into eight different categories:

  1. Environmental monitoring instruments and devices
  2. Personal protective equipment
  3. Rescue apparatus
  4. Electrical equipment and cables
  5. Machines and other equipment for carrying out mining operations
  6. Explosives and related accessories
  7. Safety materials for use in underground mines
  8. Other specific equipment and materials

An overview of equipment and materials requiring DGMS approval can be found on our list below, along with the relevant standards.

DGMS Certification Process in India

The following section provides an overview of the DGMS Approval Process in India. While this procedure is followed in most cases, there might be slight deviations for some approvals due to special circumstances or due to the unique nature of the equipment or material.


Preparation and submission of application documents


Proof of conformity with relevant standards


Submission of product tests and technical drawings


Field test is carried out


Carrying out type and routine tests


Reports and application are reviewed


DGMS approval is granted


Application for renewed approval after 1-5 years

1.The first step involves submitting all relevant application documents for the DGMS certification. These need to be prepared in the format required by DGMS and then submitted by the owner, proprietor or partner of the company seeking approval.
2.If applicable Indian Standards exist for the products to be certified, then compliance to these regulations needs to be demonstrated to the authority. This means that certain equipment requires a BIS certification prior to the DGMS approval. Equipment that does not fall under any Indian Standard needs to be compliant with internationally recognized norms (such as ISO, EN, DIN, etc.). These norms may then be accepted by DGMS for the approval process.
3.Test reports from an accredited laboratory need to be submitted together with the application, as well as technical drawings which have been approved by the laboratory.

Like most other certifications in India, non-Indian companies require an Authorized Indian Representative (AIR) for the application. The AIR must be an Indian company and serves as the main contact for the authority throughout the application process. In case applicants do not want to involve local business partners for that matter, MPR India Certification can also provide the AIR service.
4.Once all the aforementioned documents have been scrutinized and approved by the authority a “field trial approval” is granted. The validity period for the field trial approval in India is ranging from three months to one year, depending on the equipment type. After the field trial has been successfully completed, the applicant needs to submit performance reports from the user and/or DGMS officer in charge.
5.For the next step DGMS requests applicants to perform further product testing on their equipment, namely type tests and routine tests. For type tests, prototypes are being checked against the relevant standards. Routine tests are carried out by the manufacturers on-site for quality assurance.
6.Once the field trial reports and test reports have been scrutinized and approved by DGMS, the case is examined, and recommendations are made for the grant of the regular approval. If there are any shortcomings during the field trial the trial period may be extended to solve the related issues by using appropriate corrective measures.
7.When the DGMS approval has been granted by the authority, manufacturers receive unique equipment numbers for their approved products. These numbers need to be marked accordingly on the product prior to installation on-site.
8.The initial DGMS registration has a validity of 1-5 years. To apply for reapproval of their products, manufacturers must submit performance reports from their Indian users as well as BIS certificates wherever applicable to the authority.

What documents are required for the DGMS approval?

  • Application form
  • BIS certificates (if applicable)
  • Business license (in English)
  • Test reports from an accredited laboratory
  • Technical drawings approved by an accredited laboratory
  • Proof of quality control capabilities of the manufacturer (relevant licenses, testing and storage facilities, marketing and after-sales capabilities, etc.)
  • Documentation for the appointment of the Authorized Indian Representative (AIR) (only for non-Indian applicants)

DGMS Change Management

Products with a valid DGMS approval must comply with the applicable Indian regulations for DGMS registration. The applicant must assure that the authority will be notified of changes prior to change implementation. These changes include, but are not limited to:

  • Change to the product design
  • Change in the structure of the product
  • Changes to a core component
  • Change in raw material and/or material supplier

The regulations explicitly state that the authority decides in each individual case whether an official application for a change must be submitted and, if so, what the consequences are for the holders of DGMS approval as a result of the change.

It should also be noted that the Indian standards and regulations are subject to revisions and might be updated over time. In case of such updates, any equipment that has received approval in accordance with previous regulations needs to demonstrate compliance with the new regulations. In such a case, manufacturers need to need to file an application for the amendment of the existing approval.

DGMS Certification FAQ

How do I know if my products need a DGMS approval?

Most equipment, machinery, appliances and/or materials intended to be used in the Indian mining sector need to undergo the approval procedure of DGMS. Feel free to reach out to us if you would like us to check the requirements for your products.

How long does the DGMS approval process take?

After the submission of the application, the process can normally be completed within 1 year. During the first step, DGMS will scrutinize all submitted documents as part of their approval for field trial. Once the field trial has been approved, the equipment needs to be tested on-site in India, for usually a period of 6 months. In the final step the authority will scrutinize the results of the field trial and grant the final approval if they are satisfied with the outcome. This last step usually takes around 3 months.

How long is the DGMS approval valid?

The initial DGMS approval is valid for 1-5 years. The validity can also be extended when manufacturers apply for extension 60 days to 6 months prior to the approval´s expiration. How long applicants need to apply for reapproval in advance depends on the validity period of their approval.

What is the best way to prepare for DGMS approval?

All required documents should be carefully prepared before submission to the authority. Applicants need to make confirm that their products comply with the Indian requirements, especially regarding the BIS certification of their products as well as the availability of test reports issued by an accredited laboratory.

Who is eligible to act as the Authorized Indian Representative (AIR)?

The AIR must be provided by a local Indian company. The company can be the manufacturers subsidiary or a distribution partner. External service providers such as MPR India Certification can also provide this service.

In which cases are factory inspections required?

If factory inspections are required is decided on a case-by-case basis by DGMS. If the equipment also requires a BIS certification, BIS will conduct a factory inspection at the manufacturer’s premises.

Do the authorities inform DGMS certificate holders about changes in the regulations?

No, information on DGMS approvals is provided in English on the website of the Directorate General of Mines Safety (DGMS). Companies are obliged to inform themselves about changes if they have not contracted a consultancy firm to monitor changes.
