Go to any market and you will find many products ranging from cosmetics to food and heavy industrial materials sport ISI or ISO certification tags, indicating that they are safe for use and assure a certain level of quality.

Even cheap toys from wholesale markets, which on face value alone look like brittle recycled plastic, can be seen with a ‘quality’ tag, giving one a feeling that the mark is being easily used and abused by unscrupulous manufacturers.

On Friday, Food Minister K.V. Thomas indicated that some Indian companies may be churning out sub-standard products despite displaying the quality tags.

“We are getting a lot of complaints regarding the quality of tyres which have got these ISO markings,” Thomas said.

ISI is a quality tag issued by the national standards body, the Bureau of Indian Standards (BIS), while ISO tags are standards prescribed by the International Organization for Standardization, of which India is a founding member.
