Filing checklist for Mining & Extraction businesses in Maryland

  1. Step 1, Confirm coverage threshold

    All employers with one or more employees are required to carry workers' compensation insurance. For Mining & Extraction operations, this typically applies once you make a first W-2 hire, even part-time.

  2. Step 2, Pick the right class code

    Mining & Extraction businesses typically use codes like 1624, 1164, 1165. The wrong code can cost 4 to 10x more or get reclassified at audit. In Maryland, the cheapest code on this list is 4825 at $0.340 and the most expensive is 1430 at $1.69.

  3. Step 3, Get a quote

    Chesapeake Employers Insurance (formerly IWIF) is one option in Maryland; private carriers (Travelers, Hartford, Liberty Mutual, AmTrust) also write coverage. Schedule credits up to 25% are typical for low-loss accounts.

  4. Step 4, Document subcontractors

    General contractors are responsible for ensuring subcontractors carry workers' compensation coverage; otherwise, the general contractor may be liable for injuries to the subcontractor's employees. Mining & Extraction operators with crews of 1099s should keep certificates of insurance for every sub, otherwise the GC absorbs the sub liability at audit.

  5. Step 5, Annual audit

    Carriers audit payroll within 90 days of policy expiration. Have payroll segregated by class code, job descriptions on file, and overtime properly excluded from rated payroll. Mining & Extraction class allocation can shift if any worker spends more than 50% of time on a different code.

Penalty for non-coverage in Maryland: Employers failing to carry workers' compensation insurance may face fines, stop-work orders, and personal liability for injured workers' benefits.
