What Is General Average? The Most Critical & Overlooked Risk Rule in Ocean Shipping

General Average (GA) is a century-old universal legal and adjustment principle in international ocean shipping. It is a core concept that everyone involved in container shipping or bulk cargo must understand—it is completely different from ordinary cargo damage, and directly determines whether you have to pay extra compensation after your goods are rescued.

1. What Is General Average in Simple Terms?

A vessel voyage involves three interests: the ship itself, the cargo on board, and the freight.

When the vessel and cargo face a real, imminent common danger (such as typhoon, grounding, fire, sinking risk), the captain intentionally and reasonably makes a sacrifice or incurs extra expenses to save the ship and most of the cargo.

Such losses and costs are defined as General Average.

The key rule:
The loss is NOT borne by the shipowner alone, nor by one single shipper. All saved parties (ship, cargo, freight) must contribute proportionally based on their saved value.

Core logic:
One sacrifices for the common good; all beneficiaries share the cost.

2. 4 Strict Conditions to Constitute General Average

All 4 must be satisfied:

The danger is COMMON
Threatens both the ship AND the cargo (not just one side).
The danger is REAL & IMMINENT
Not a predicted or potential risk—disaster is about to happen.
The action is INTENTIONAL & REASONABLE
Voluntary decision by the master, not an accident; the measure must be logical.
The sacrifice is EFFECTIVE
The ship and/or cargo are partially saved. If everything sinks, there is no General Average.

3. Typical Examples of General Average

These are common in real shipping:

Jettison of cargo
To lighten the ship and avoid sinking, the captain orders containers overboard.

→ The lost cargo = General Average.
Voluntary stranding
Intentionally grounding the ship to prevent sinking.

→ Hull damage and repair costs = General Average.
Fire-fighting sacrifices
Drilling holes to flood holds, or using chemicals that damage goods to put out a fire.

→ Related damage and costs = General Average.
Salvage & refuge port expenses
Costs of tugboats, temporary repairs, port fees, storage, and reloading at a refuge port.

→ All these fees = General Average.
Crew and fuel expenses during rescue
Extra costs to save the vessel and cargo.

4. What Is NOT General Average?

These are Particular Average—borne only by the affected party (or their own insurance):

Cargo washed overboard by waves
Damage due to machine breakdown or crew negligence
Spoilage due to poor packaging
Theft, piracy, or war risks (usually covered under special additional risks)

5. How Is General Average Adjusted & Shared?

Golden rule:
Who is saved? Who benefits? Who contributes.

Contribution is based on proportion of saved value:

Shipowner: based on the saved value of the vessel
Shipper: based on the saved value of their cargo
Freight carrier: based on the earned freight

Simplified example:
Total saved value (ship + cargo): $100,000,000

Your cargo value: $1,000,000
Total General Average loss: $1,000,000

Your contribution:
$1,000,000 × (1,000,000 / 100,000,000) = $10,000

6. Procedure When General Average Is Declared

GA Declaration
The shipowner officially declares General Average.
GA Adjustment
Professional average adjusters calculate total losses and each party’s share.
GA Security
The shipowner WILL NOT release cargo until you provide:
- Average Bond
- Cash deposit or insurance guarantee
Delivery & Final Settlement
Take delivery first; pay the contribution later (usually handled by cargo insurance).

7. General Average vs. Particular Average

Item	General Average	Particular Average
Cause	Intentional sacrifice to save all	Accidents, natural disasters
Bearer	Shared by ALL saved parties	Borne only by the damaged party
Scope	Ship + cargo + freight	Only one shipper or shipowner
Time to settle	Slow (months for adjustment)	Fast (direct insurance claim)

8. Why You Must Understand General Average

No cargo insurance = huge financial risk
Even if your cargo is undamaged, you still must contribute.
No security = no delivery
Without a guarantee, your cargo will be held at the port.
90% of major marine accidents trigger GA
Fire, grounding, typhoon, salvage almost always involve General Average.
It is a fair, long-established maritime rule
Encourages captains to save lives and cargo, rather than abandon them for fear of cost.

One-Sentence Summary

General Average means: when a ship is in danger, sacrifices made to save the whole voyage are shared proportionally by all saved parties.

For any international ocean shipment, cargo insurance is essential—it is the main protection against General Average contribution.
