Service Overview

What is WMI Model Approval in India?

WMI model approval, commonly referred to as Weights and Measures Instrument Model Approval, is a regulatory process under Section 22 of the Legal Metrology Act, 2009. The applicable provisions require approval of the model of a weight or measure before its manufacture or import into India, subject to prescribed rules and exemptions. The detailed procedure is governed by the Legal Metrology (Approval of Models) Rules, 2011, as applicable.

Model approval assesses whether a particular design of a weighing or measuring instrument meets the prescribed metrological and technical requirements. Depending on the instrument category, the process may involve technical documentation, examination of the model, prescribed testing and evaluation by the competent authority.

Eminence Global Compliance Group provides WMI model approval consultancy in India, including regulatory applicability assessment, documentation assistance, testing coordination and application follow-up. We help businesses understand the applicable Legal Metrology requirements and prepare for the relevant approval process.
