The Ministry of Commerce & Industry, specifically the Department for Promotion of Industry and Internal Trade (DPIIT), Government of India, regularly issues Quality Control Orders (QCOs) under the aspect of Environment, Health & Safety (EHS) to regulate various types of goods imported into or manufactured locally within the country. The objective is to foster a safe and quality-centric environment nationwide.
In line with this objective, a recent QCO has been issued to regulate “High Strength Structural Bolts”. This product falls under the mandatory BIS-ISI Mark certification scheme (Scheme-I of Schedule II), making it mandatory for manufacturers and importers to obtain a valid license by a specified deadline. Failure to comply will lead to the prohibition of importing, manufacturing or selling these goods in the Indian market.
Certification plays a crucial role in ensuring that products meet specific quality and safety standards mandated by the government. Its implementation aims to safeguard consumers, promote standardization, uphold public health and safety, facilitate international trade, and stimulate economic development.
To achieve BIS certification, products must fully comply with all parameters outlined in the corresponding Indian Standard. This ensures that products meet stringent quality and safety requirements, bolstering consumer confidence and advancing industry standards.
