The minimum compliance checklist depend upon nature of work, number of employees, Industry and other applicable acts.
Pls note some basic compliance:-
BOCW Act (Till the establishment covered under Factory Act, post covering under Factory Act, BOCW is not applicable).
Maternity Benefit Act
Leave rules (as per applicable act whether S&E Act, Contract Labour Act etc.).
Sexual Harassment of Woman Act,
Minimum Wages Act,
Payment of Wages Act,
The Employees Compensation Act
CL (R&A) Act, 1970 or CL (R&A) Central Rule, 1971
Since yours is a manufacturing company which may involve hiring personnel through various sub-contracts so CL (R&A) Act, 1970 also applicable. You have to take care about the commercial and legal agreements with the petty contractors (manpower, security, transport, housekeeping etc) and timely renewal of such agreements. You can check the statutory compliance of the petty contractors as well on monthly / quarterly basis.
Senior can suggest more points.
