✅ What is a Model Approval Certificate?
The Model Approval Certificate is a legal document issued by the Director of Legal Metrology, Ministry of Consumer Affairs, Government of India. It certifies that a particular model of a weighing or measuring instrument has been tested and conforms to the standards prescribed under the Legal Metrology Act, 2009 and Legal Metrology (General) Rules, 2011.
This certificate is required before manufacturing, importing, or selling such instruments in India.
🔍 Who Needs Model Approval?
Model approval is compulsory for:
-
Indian manufacturers producing weighing and measuring instruments
-
Importers bringing devices into India for commercial sale
-
OEMs and startups launching new models in the Indian market
-
Distributors and traders looking to sell compliant instruments
If your business deals with instruments like digital weighing scales, fuel dispensers, water meters, or flow meters, obtaining this certificate is non-negotiable.
📌 Why is Model Approval Important?
1. Legal Requirement
As per Indian law, any unapproved model of weighing or measuring device cannot be sold or used commercially. Violations can lead to fines, product seizures, and even cancellation of licenses.
2. Market Credibility
A model approval certificate is often a prerequisite for bulk buyers, institutional clients, and government tenders. It enhances the credibility and marketability of your product.
3. Assurance of Accuracy
The testing process ensures that the model meets the required standards of accuracy, design, safety, and performance, making it reliable for trade and commercial use.
