BIS certification for insulated flasks is mandatory under IS 17790:2022 as per the Quality Control Order. This guide explains applicability, required tests, certification process, timelines, and how Standphill India supports manufacturers and importers in achieving ISI Mark compliance in India.

BIS Certification for Insulated Flask for Domestic Use – IS 17790:2022

A BIS ISI Mark Certification is now mandatory in India for insulated flasks, bottles, and containers used for storing hot or cold beverages. This certification ensures compliance with Indian Standard IS 17790:2022 and is enforced by the Bureau of Indian Standards (BIS) under the Quality Control Order 2024 to guarantee product safety, thermal performance, and consumer protection.

Any manufacturer, importer, or seller of insulated flasks for domestic use must obtain valid BIS certification with the ISI Mark to legally market their products in India after the specified compliance deadlines.

Overview of BIS QCO for Insulated Flasks (2024 Amendment)

The Ministry of Commerce and Industry, Government of India has notified the Insulated Flask, Bottles, and Containers for Domestic Use (Quality Control) Amendment Order, 2024, making BIS certification mandatory for insulated flasks intended for domestic use.

This Quality Control Order (QCO) came into force on 29 August 2024, and mandates that insulated flasks, bottles, and containers used for storing hot or cold beverages must conform to Indian Standard IS 17790:2022 and bear the ISI Mark under a valid BIS license.

The objective of this regulation is to ensure product safety, thermal performance, material quality, and consumer protection across the Indian market.

Key Amendment Explained – Transitional Relaxation for Existing Stock

The 2024 Amendment introduced a critical proviso to Paragraph 2 of the original QCO:

Products manufactured or imported before the commencement date of the Order may be sold or displayed for up to six months

The manufacturer or importer must:

ii. ) Submit a declaration certified by a Chartered Accountant to BIS

This relaxation applies only to existing stock.

After the transition period, non-certified insulated flasks cannot be sold, imported, or distributed in India.
