To protect human health and the environment, the Bureau of Indian Standards (BIS) standard for Toluene Diisocyanate will be made mandatory.

The directive stipulates that both domestically manufactured and imported Toluene Diisocyanate must conform to Indian Standard IS 17916: 2022 and bear the standard mark, obtained through BIS licensing under Scheme-II of Schedule-II of the Bureau of Indian Standards (Conformity Assessment) Regulations, 2018.

Compliance will be governed by the Bureau of Indian Standards Act of 2016 and its associated Rules and Regulations, with BIS serving as the certifying and enforcing authority.
