Common questions

How many workers make a unit a factory under the OSH Code?

20 or more where a manufacturing process runs with power, or 40 or more without, counted on any day of the previous twelve months (s. 2(1)(w)). Where a state's law set a different number before the Code, that number applies.

Does a white-category unit need pollution consent?

No Consent to Establish or Operate since the November 2024 notifications — but it must still intimate the State Pollution Control Board.

Can my buyer delay paying me beyond 45 days?

Not without cost, if you are a Udyam-registered micro or small enterprise: s. 15 of the MSMED Act caps credit at 45 days, s. 16 adds compound interest at three times the bank rate, and the buyer cannot claim the expense for tax until it pays (Income-tax Act, 2025, s. 37(2)(g)).

Before you rely on this

A checklist, not advice for your business. Several of these duties are set by each state, and most depend on your size and how you are registered — confirm with your CA before relying on any one of them.
