If you’re a manufacturer, importer, or seller in India, understanding the difference between BIS and Legal Metrology is more than just a formality, it’s a must for smooth operations. Two of the most critical standards you’ll come across are the Bureau of Indian Standards (BIS) and Legal Metrology.
Knowing the differences between BIS and Legal Metrology is important for developing customer trust, preserving your brand, and avoiding fines. These standards aim to ensure fairness in the marketplace, but in different ways.
