BIS Certification for Stainless Steel Vacuum Flask/Bottle IS 17526:2021

Domestic stainless steel vacuum flasks and bottles are widely used for storing hot and cold beverages in households, offices, travel, and outdoor environments. To ensure product safety, thermal efficiency, material hygiene, and durability, the Government of India has made BIS certification mandatory for these products under the Insulated Flask, Bottles, and Containers for Domestic Use (Quality Control) Order.

As per the latest Quality Control Amendment Order, 2024, all stainless steel vacuum flasks and bottles for domestic use must comply with Indian Standard IS 17526:2021 and bear a valid ISI Mark issued by the Bureau of Indian Standards (BIS).

What Is a Domestic Stainless Steel Vacuum Flask/Bottle?

A domestic stainless steel vacuum flask or bottle is a double-walled insulated container manufactured using food-grade stainless steel. It uses vacuum insulation technology between the inner and outer walls to minimize heat transfer.

Key characteristics:

i. ) Long-lasting hot and cold temperature retention

ii. ) Leak-proof and spill-resistant design

iii. ) Corrosion-resistant stainless steel body

iv. ) Safe for food and beverage contact

v. ) Suitable for daily domestic use

Because these products come in direct contact with consumables, strict quality and safety regulation is essential, which is why BIS certification has been enforced.
