Sub-category determines the business entirely
Identify what the business actually makes or distributes. Specialty chemical manufacturers produce branded formulations for specific industries (water treatment, oil and gas, food and beverage processing, etc.). Industrial chemical distributors stock and deliver bulk and packaged chemicals from major manufacturers (Univar, Brenntag, etc. are the giants). Cleaning chemical formulators serve facilities maintenance markets. Each is a distinct business. Verify the exact product categories, the value-add (manufacturing vs. distribution), and the customer industries served.
