Introduction
IS 302 Part 1: 2024 guides the safety checks for humidifiers placed in living rooms, work areas, and many public spots. Humidifiers continually release moisture, making the air more enjoyable. It describes what the product must do to be safe when operating. Any humidifier that enters, leaves, or is sold in India must follow BIS rules. The ISI mark on the device shows that the product matches the set safety rules.

Businesses must hold a valid BIS licence and pay the needed fees so that customs clearance happens without delay. Companies must also follow the QCO order, which helps keep the product quality steady. BIS approval lifts acceptance in the market and gives buyers more confidence. Online support from BIS has made the process simple for both importers and manufacturers.
