Model Approval Certificate: A Must-Have for Manufacturers & Importers

What is a Model Approval Certificate?

A Model Approval Certificate is a legal permit issued by the Directorate of Legal Metrology, Government of India. It certifies that a specific model of a weighing or measuring instrument has been tested and complies with the Indian Standards prescribed under the Legal Metrology Act, 2009.

No model of a weighing or measuring instrument can be manufactured, imported, sold, or used in India without this approval.

Who Needs Model Approval?

If your business deals with the design, production, import, or distribution of any type of weighing or measuring device, model approval is mandatory.

Here’s who needs it:

• Manufacturers launching new models of instruments

• Importers bringing in foreign-manufactured measuring devices

• OEMs and third-party producers making devices for Indian brands

• Startups and businesses entering the measuring equipment market

Whether you are in the industrial, retail, scientific, or commercial sector—if your product measures anything, you’ll need model approval before launch.

Why is Model Approval Important?

✔ Legal Requirement

Without a valid Model Approval Certificate, you’re not legally allowed to market, sell, or use the measuring instrument in India. Non-compliance can result in heavy penalties and product seizures.

✔ Builds Buyer Confidence

Customers and B2B buyers prefer products that are government-approved. A model approval acts as a mark of trust and assurance.

✔ Ensures Product Accuracy

Model approval testing checks the precision, performance, and stability of the model—ensuring it meets Indian standards of accuracy.

✔ Opens Market Access

Government departments, public procurement agencies, and large retailers often require model approval as a prerequisite to business contracts.

Instruments That Require Model Approval

Model Approval is needed for a wide range of devices, including:

• Electronic and mechanical weighing scales

• Platform and counter scales

• Weighbridges

• Water meters and flow meters

• Fuel dispensers

• Taxi meters and fare meters

• Laboratory balances

• Volumetric devices

• Automatic filling instruments

Who Issues the Certificate?

The certificate is issued by the Director, Legal Metrology, Ministry of Consumer Affairs. Testing is done by authorized labs, including:

• RRSLs (Regional Reference Standard Laboratories)

• IILM (Indian Institute of Legal Metrology)

• Other certified government laboratories

Documents Required for Model Approval

To apply for a Model Approval Certificate, the following documents are typically needed:

1. Application form (Form LM-1)

2. Technical drawings and specifications of the model

3. Instruction manual or brochure

4. Details of internal components and working mechanism

5. Manufacturing license (for domestic manufacturers)

6. Importer license (for importers)

7. Declaration of conformity

8. Brand ownership proof (if applicable)

9. Power of attorney (if applying through a consultant)

10. Applicable government fees

Our team at Agile Regulatory ensures that your documentation is complete, correct, and submitted in the required format—reducing chances of rejection or delay.

Step-by-Step Process of Model Approval

Here’s how the model approval process works:

Step 1: Document Preparation

We begin by collecting all necessary documents and technical specifications of your product.

Step 2: Application Submission

The application is filed with the Legal Metrology Department, along with sample instruments and fees.

Step 3: Sample Testing at Lab

A designated lab conducts technical tests to ensure the instrument meets Indian standards for accuracy, repeatability, and construction.

Step 4: Review by Legal Metrology

Based on test reports, the department evaluates the application. If all parameters are met, the certificate is approved.

Step 5: Issuance of Certificate

You receive a Model Approval Certificate valid for 5 years, which can be renewed upon expiry.

Timeline and Validity

• Processing Time: Usually takes 6 to 10 weeks depending on the lab workload and type of instrument.

• Validity: Certificate is valid for 5 years, with the option to renew.

• Renewal: If there are no changes in the model’s design or performance, re-testing may not be required.

Challenges Faced During Model Approval

Getting a Model Approval Certificate can be time-consuming if you're unfamiliar with the process. Common issues include:

• Delays due to incomplete or incorrect documentation

• Miscommunication with test labs

• Application rejection due to technical non-compliance

• Lack of clarity on legal or procedural requirements
