Industry identifies the economic activity or sector in which the borrower earns revenue, such as manufacturing, trading, services, construction, food processing, textiles, logistics, or healthcare. In MSME underwriting, industry classification helps the lender compare margins, working-capital cycle, seasonality, regulatory risk, and business outlook with relevant peers. For example, inventory days that are normal in a manufacturing unit may be unusual for a service business. Industry also affects policy eligibility, exposure limits, sensitive-sector tagging, and monitoring requirements. It matters because the same financial ratio can mean different things across sectors. The common mistake is to use broad or incorrect industry labels; classification should be based on actual revenue activity, not only registration description or promoter preference.
