Marine Cargo and Transit Insurance for Shipping to Nigeria: The Complete 2026 Guide
A carrier's liability barely covers a fraction of your cargo's value. Here is how marine cargo and transit insurance really works on a UK to Nigeria shipment: what it covers, the Institute Cargo Clauses, General Average, and how to claim.
The gap most people miss
Why the Carrier's Liability Is Not Enough
Many shippers assume the carrier is fully responsible if something goes wrong. In reality, international conventions cap a carrier's liability at a fixed amount per kilogram, and only if the carrier is proven at fault. That cap is far below what most cargo is actually worth.
| Mode | Convention | Liability cap | Roughly |
|---|---|---|---|
| Sea | Hague-Visby Rules | 2 SDR / kg | about £2 / kg |
| Air | Montreal Convention | 22 SDR / kg | about £24 / kg |
| Road | CMR Convention | 8.33 SDR / kg | about £9 / kg |
An SDR (Special Drawing Right) is an IMF currency unit worth roughly £1.10. So a 20kg box of electronics worth £1,500, lost at sea, might attract carrier compensation of only about £40. Marine cargo insurance is what covers the other £1,460.
The three levels of cover
The Institute Cargo Clauses: A, B and C
Marine cover worldwide is standardised through the Institute Cargo Clauses, published by the London insurance market. There are three levels, from widest to narrowest.
| Clause | Cover | Typical use |
|---|---|---|
| ICC (A) | All risks: accidental loss or damage from any external cause, except the standard exclusions. | Most cargo. The recommended, widest cover. |
| ICC (B) | Named perils including fire, sinking, collision, water damage, jettison and General Average. | Lower-value or robust goods. |
| ICC (C) | Major casualties only: fire, vessel sinking or stranding, collision, jettison and General Average. No theft or water damage. | Bulk, low-risk cargo. The most basic cover. |
For most personal and commercial shipments to Nigeria, an all risks (ICC A) policy gives the broadest protection and the fewest surprises at claim time.
The risk nobody expects
General Average: When Everyone Pays
What it is
Under the York-Antwerp Rules, if the crew sacrifices cargo or spends extraordinary sums to save the whole voyage, for example jettisoning containers or paying salvage after a fire, every cargo owner contributes proportionally, even if their own goods were untouched.
Why insurance matters
Without insurance, you must pay your General Average share and post a bond or deposit before your cargo is released, which can run into hundreds or thousands of pounds. A marine policy responds to General Average on your behalf, so your goods are freed without a surprise bill.
Insure the right amount
How Much Cover to Buy, and What It Costs
The CIF + 10% rule
Insure the Cost of the goods + Insurance + Freight, plus a 10 percent margin for incidental costs and expected profit. Example: £2,000 of goods with £300 freight is insured for about £2,530, so a total loss leaves you no worse off.
What the premium costs
Premiums are a small percentage of the insured value, commonly around 0.3 percent to 1 percent depending on goods, route and packing. On £2,500 of cover that is often just £10 to £25, a fraction of what you would lose uninsured.
Cover runs warehouse to warehouse. A transit policy protects your goods from the moment they leave, through the sea or air leg and customs, until they reach the destination, subject to the policy's time limits after discharge.
Read the small print
What Cargo Insurance Does Not Cover
Even an all risks policy has standard exclusions. Knowing them helps you avoid a rejected claim, and most are within your control.
Inadequate packing
Loss caused by insufficient or unsuitable packing for the journey is excluded, which is why professional packing matters.
Inherent vice
The natural behaviour of the goods themselves, such as perishables spoiling or metals rusting over time, is not covered.
Delay
Loss of market or financial loss caused purely by delay is excluded, even if the delay itself was covered.
Ordinary wear and leakage
Ordinary leakage, loss in weight or volume, and normal wear and tear are not insured events.
War and strikes
War, strikes, riots and civil commotion are excluded unless the War and Strikes clauses are specifically added.
Wilful misconduct
Loss deliberately caused by the insured, and shipping prohibited or illegal goods, are never covered.
If the worst happens
How to Make a Cargo Insurance Claim
Inspect on delivery
Check the cargo before you sign. Note any visible damage or shortage on the delivery receipt or POD.
Preserve the evidence
Do not throw away packaging. Photograph the damage, the packaging and the labels straight away.
Notify promptly
Tell R-Zone and the insurer as soon as possible, within any time limit stated in the policy.
Submit and survey
Provide the invoice, packing list and bill of lading, complete the claim form, and allow a survey if requested.

Cargo Insurance FAQs
Do I need marine cargo insurance to ship to Nigeria?
It is strongly recommended. A carrier's legal liability is capped very low, roughly 2 SDR per kg by sea under the Hague-Visby Rules (about £2 per kg), which rarely reflects your goods' real value. Marine cargo insurance covers the gap so you are reimbursed for the actual insured value if goods are lost or damaged in transit, regardless of whether the carrier was at fault.
What does transit insurance cover?
A comprehensive 'all risks' policy (Institute Cargo Clauses A) covers accidental physical loss or damage from most external causes in transit, warehouse to warehouse. It excludes inadequate packing, inherent vice, ordinary wear, delay, and war or strikes unless those clauses are added. Clauses B and C are narrower, covering named perils only.
How much cover should I buy?
The market standard is CIF plus 10 percent: the cost of the goods, plus insurance and freight, plus a 10 percent margin for incidental expenses and expected profit. So £2,000 of goods with £300 freight would be insured for about £2,530. Insuring the full value means a total loss leaves you no worse off.
How much does cargo insurance cost?
Premiums are a small percentage of the insured value, commonly in the region of 0.3 percent to 1 percent or more depending on the goods, the route, the packing and the cover level. On £2,500 of cover that is often only £10 to £25. R-Zone can arrange cover and quote the exact premium for your shipment.
What is General Average and why does it matter?
Under the York-Antwerp Rules, if the ship's crew sacrifices cargo or incurs extraordinary expense to save the whole voyage (for example jettisoning cargo or salvage after a fire), every cargo owner must contribute proportionally, even if their own goods were fine. Without insurance you must pay your share and post a bond before your cargo is released. A marine policy responds to General Average for you.
How do I make a claim?
Note any visible damage on the delivery receipt, do not discard the packaging, photograph everything, and notify the insurer promptly (usually within a set number of days). Keep your commercial invoice, packing list and bill of lading, complete the claim form, and allow a survey if requested. R-Zone helps you gather the documents and file the claim.
