Product packaging is more than just an attractive box or label. It serves as a crucial medium of communication between businesses and consumers. Legal metrology ensures that this communication is fair, transparent, and accurate. In this blog, we will explore the importance of legal metrology in product packaging, the rules businesses must follow, and how these regulations protect consumers and promote trust in the market. 

What is Legal Metrology? 

Legal metrology refers to the laws and regulations that govern measurements and measuring instruments. These rules are essential for ensuring accuracy and fairness in trade. The Legal Metrology Act, 2009, in India, provides the framework to regulate pre-packaged commodities and ensure that consumers are not misled by incorrect measurements or misleading product information. 

Obtaining a legal metrology certificate or an LMPC certificate is mandatory for businesses dealing with pre-packaged commodities. These certificates verify that the packaging and labeling comply with the rules under the Legal Metrology Act. 

Why is Legal Metrology Important for Product Packaging? 

Product packaging often contains critical information such as the product's weight, price, quantity, and expiry date. Legal metrology ensures that this information is accurate and presented in a standardized way, allowing consumers to make informed choices.

2. Font Size and Legibility 

The declarations must be easy to read, with specific font sizes prescribed for different packaging dimensions.

Products must be measured and declared using the metric system, such as grams, kilograms, milliliters, or liters. This measurement must align with the weight and measurement certificate standards issued under legal metrology laws. 

4. Barcode and QR Codes
