ISI Mark for Steel and Iron Products Manufacturer

The kind and location of your firm determine whether you need a steel and iron product license. Important procedures include registering your company, getting the relevant industrial and trade permits, and adhering to environmental and safety requirements. If you manufacture, you may require an industrial license and pollution control clearance. Import/export requires registration with customs officials. Tax registration, such as VAT/GST, is required. Quality certifications such as ISO or conformity with industry standards may be required. The application procedure entails completing documents, paying fees, and undergoing inspections. Requirements differ by nation, therefore consulting with local regulatory organizations is recommended.

Frequently Asked Questions

The NOC (National Occupational Classification) code for steel fabricators in Canada is 7235, covering structural metal and platework fabricators and fitters.

The NOC code for steel product manufacturing workers varies but generally falls under 9411 for metalworking and forging machine operators.

ISI stands for Indian Standards Institute, which certifies the quality and safety of steel and other industrial products in India.

Businesses in manufacturing, construction, import/export, and industries requiring environmental, safety, or trade compliance typically need a No Objection Certificate (NOC) from relevant authorities.

The NOC code for manufacturing varies by industry, but 9617 (labourers in metal fabrication) and 9231 (central control operators) are common in steel manufacturing.
