Documents Required for a Manufacturing Business, Using a Rice Mill
A rice mill is a factory: paddy in, rice, bran and husk out. What a manufacturing unit needs, from factory licence and pollution consent to EPFO and FSSAI.
A rice mill is the manufacturing business I know: paddy goes in; rice, bran, husk and broken rice come out. It also sits where several rulebooks overlap. Whether it is a factory depends on its headcount and power; where it lands on the pollution scale depends on whether it parboils; it is a food business because its output is rice; and it is a weighing business because every purchase from a farmer is priced by weight. The licences a mill like ours has to think about make a good map of what any manufacturing unit faces. Among the licences our mill holds are a factory licence, pollution consent, a fire NOC and FSSAI, and its weighbridge is stamped.
Manufacturing draws in more of the business-registration map at once than almost any other activity: structure, tax, premises, pollution and labour-law requirements stack on top of each other instead of arriving one at a time. This checklist, one of several organised by what a business actually does, covers what a manufacturing business needs, separating what applies to every manufacturer from what depends on your worker count and activity.
The foundation, same as any business
- PAN (personal, if a proprietor; entity PAN if a partnership, LLP or company).
- Business-structure registration: incorporation through the MCA for an LLP or company, partnership deed registration for a partnership.
- GST registration, mandatory once turnover crosses the threshold, or immediately if you supply taxable goods inter-state, which is common for manufacturers selling beyond their home state. See GST Registration Documents for Proprietorship.
- Udyam registration: free, voluntary, and particularly useful for manufacturers, because priority-sector lending and, for micro and small units, the 45-day payment protection apply directly to working-capital-heavy activities like this.
Premises: Shops and Establishments or a factory licence, not both
This is the first fork that belongs to manufacturing. Under the OSH Code, which replaced the Factories Act from 21 November 2025, a "factory" is defined as a premises engaging 20 or more workers using power in the manufacturing process, or 40 or more without power, up from the earlier 10/20 thresholds. If your unit meets this definition, it is regulated by a factory licence from your state's factory inspectorate, not by Shops and Establishments, which explicitly excludes factories from its scope. If you are below the threshold, your premises falls under standard Shops and Establishments registration instead.
Given how recent the threshold change is, and the state-by-state pace of the implementing rules, confirm your specific state's current position directly rather than relying only on the central figure if your worker count is anywhere near the line.
Pollution clearance: category-dependent, not optional to check
Manufacturing that involves emissions, effluent or waste, which covers a wide range of processing from textiles to food milling to metalwork, falls under the CPCB's Red/Orange/Green/White classification. Red, Orange and Green categories need Consent to Establish before construction and Consent to Operate before operations start, from your State Pollution Control Board. See Consent to Establish vs Consent to Operate for the full framework. Do not assume your specific process is exempt (White category) without confirming; this is one of the costlier categories to get wrong, since operating without required consent can mean closure orders, not just a fine.
Employment-linked registrations
- EPFO registration: mandatory at 20 or more employees. See EPFO Registration Applicability.
- ESIC registration: mandatory at 10 or more employees (the same threshold now applies to factories and other establishments under the Code on Social Security). See ESIC Registration Applicability.
- TAN, once you deduct TDS on any employee salary or contractor payment.

Activity-specific additions
- FSSAI registration or licence, if your output is food in any form. This applies on top of, not instead of, factory and pollution requirements. See FSSAI Registration vs State Licence vs Central Licence.
- Legal Metrology: verification and stamping of every scale or weighbridge used in trade, and a packaged-commodity certificate if you sell your output in pre-packaged form with a declared quantity.
- Import Export Code, if any of your raw material sourcing or finished-goods sales crosses an international border. See Import Export Code (IEC).
- Fire NOC, if your premises size, height or activity risk crosses your state's threshold; commonly relevant for larger manufacturing units and anywhere handling flammable material. See Fire NOC for Businesses.
Where a mill differs from the textbook factory
Most manufacturing checklists are written with a factory floor in mind: machines, a shift, a finished product. A rice mill has all of that, and four things I would add to any list for a mill:
- The weighbridge. Paddy is bought by weight, so the weighbridge and every scale used to price a purchase must be verified and stamped under Legal Metrology. It is the item an inspector can check in a minute, and the one both sides of every purchase rely on.
- The packed rice. Rice sold in packs with a declared net quantity brings in the packaged-commodity rules: net quantity, packer details, date of packing and MRP on every bag.
- The parboiling decision. CPCB's 2025 list puts a parboiled rice mill (with soaking and steam or a drier) in Orange and a raw rice mill or huller in Green. That is a process choice with a compliance price, and I'd make it knowing both.
- The season's headcount. A mill needs the most hands when paddy is arriving. EPFO coverage, once triggered at 20, does not reverse when the season ends, and contract labour counts toward the number. I would count heads at the peak, not in the quiet months.
Husk and bran come off the line every working day, and a godown full of paddy is a great deal of stored fuel, which is why the fire question deserves an honest answer at a mill even when the building looks ordinary. For the money side of running a mill, the site's rice mill finance tracker keeps procurement, stock and receivables in one place.
A worked sequence for a mid-sized manufacturing unit
A unit with 15 workers (using power), processing a raw material into a finished good, selling both locally and inter-state, with moderate effluent:
- Structure and PAN, then Udyam registration (immediate, no cost).
- GST registration (mandatory because of the inter-state supply of taxable goods, regardless of turnover).
- Shops and Establishments registration: 15 workers with power sits below the revised 20-worker factory threshold, so this unit is not yet a "factory" for licensing purposes, though this should be confirmed against the state's current rules.
- Consent to Establish from the State Pollution Control Board before any construction, then Consent to Operate before production starts, with the category confirmed directly with the board, since "moderate effluent" could plausibly be Orange or Green.
- Fire NOC, if the premises size or height crosses the state threshold.
- ESIC registration once headcount reaches 10 (so this 15-worker unit is already covered).
- EPFO registration once headcount reaches 20: not yet triggered at 15, but worth watching closely as the unit grows.
Four mistakes manufacturers make with this list
- Assuming factory licensing and Shops and Establishments both apply. They are alternatives based on the factory threshold, not additive requirements.
- Skipping pollution clearance because the activity "doesn't feel" polluting. Confirm your Pollution Index category directly rather than assuming.
- Treating FSSAI as irrelevant to manufacturing. Any manufacturing with food output needs it, in addition to the standard manufacturing compliance.
- Not tracking the worker count against both the EPFO (20) and factory-licence (20 with power / 40 without) thresholds at the same time. They are separate triggers that happen to share the number 20 in one common case, which causes confusion about which obligation is actually active.
Before you commit to the building
- Count your current workforce against the ESIC (10), EPFO (20) and factory-licence (20 with power/40 without) thresholds separately; they are not the same trigger.
- Confirm your manufacturing activity's Pollution Index category with your State Pollution Control Board before assuming exemption.
- If your output is food in any form, add FSSAI to your list; it does not substitute for, and is not substituted by, factory or pollution compliance.
- Sequence pollution clearance (Consent to Establish) and the Fire NOC before committing to construction or fit-out, not after.
