Plant, Machinery & Stock Insurance

What does plant, machinery & stock insurance cover?

Machinery is the backbone of any factory or industrial unit — and a sudden breakdown can halt production, delay deliveries and cause heavy financial loss. Plant, machinery & stock insurance protects your physical assets and inventory against unexpected damage, breakdown and loss, so one mishap doesn't unravel years of work.

It isn't a single policy but a set of covers you combine to match your operation — machinery breakdown, stock, deterioration of stock, boiler, electronic equipment and, for larger units, a single Industrial All Risk wording. I help manufacturers and MSMEs build the right mix.

Machinery Breakdown (MBD) insurance

Machinery Breakdown insurance covers sudden and unforeseen physical damage to your machinery from internal causes — electrical surges, short circuits, mechanical failure or operator error — paying the cost to repair or replace the damaged parts.

• Covers: electrical & mechanical breakdown, short circuit, operator error, vibration/misalignment.
• For: motors, generators, turbines, compressors, pumps, CNC machines and production equipment.
• Optional extensions: express freight, air freight, third-party liability, custom duty, escalation.
• Excludes: normal wear and tear, gradual deterioration, pre-existing/known defects, and consequential losses unless added.

MBD vs Fire policy — why you need both

This is the most misunderstood point in factory insurance. A Fire policy covers loss to property from fire, lightning and natural perils — but excludes internal machinery breakdown. An MBD policy covers the breakdown itself, but excludes the fire/natural perils that the Fire policy handles. They're complementary: together they give your machinery complete protection.

Stock insurance

Stock insurance protects your inventory — raw material, work-in-progress and finished goods — against fire, burglary and other insured perils. Because stock value rises and falls (especially seasonally), it's often insured on a declaration basis, where you periodically declare actual stock value and pay premium accordingly.

• Raw material, WIP, finished goods — at your premises or godown.
• Declaration policy for fluctuating stock levels — pay for what you actually hold.
• Can be combined with building, machinery and liability in a package.

Deterioration of Stock (cold storage)

For businesses storing perishables, Deterioration of Stock cover protects goods in cold storage that spoil due to a covered machinery breakdown or power failure affecting refrigeration — vital for food, pharma and cold-chain operations.

Boiler, Electronic Equipment & Contractors Plant

Industrial All Risk (IAR)

For larger units (typically sum insured above ₹50 crore), Industrial All Risk combines fire, machinery breakdown and business interruption under a single wording — simpler administration and broader, gap-free cover. It's the preferred route for mid-to-large factories.

Avoid under-insurance & the average clause

Most factory claims get reduced because of under-insurance. If you insure machinery or stock for less than its real replacement value, the average clause applies — your claim is cut in the same proportion. For example, insuring assets at 60% of value can mean only 60% of a partial claim is paid.

How to claim — step by step

1. Intimate immediately: Inform the insurer (and me) as soon as the breakdown or loss occurs; don't dismantle before survey.
2. Survey: A surveyor inspects the damaged machinery/stock and assesses the cause and loss.
3. Documents: Submit the claim form, policy, purchase/maintenance records, repair estimate and (for theft) FIR.
4. Approval: The insurer confirms the cause is covered and approves the admissible amount.
5. Settlement: Repair/replacement cost is paid so you can resume production.
