Ad Valorem Insurance

Ad valorem insurance compensates for goods based on their declared value, not their weight. It is intended for shippers whose goods are worth significantly more than what the carrier’s liability limits cover: a Carrier on a per-kilogram basis, meaning that a high-value package that is lost is covered for only a fraction of its actual value.

This guide explains exactly what the term means, how it differs from Carrier"declared value" option, how the coverage works, what it actually costs, and in which cases it is not worth it.

What is ad valorem insurance?

"Ad valorem" comes from Latin and means "according to value." In freight transport, the term refers to a basis for valuation: compensation calculated based on the declared value of the goods, as opposed to compensation calculated based on weight.

This clarification of terminology is not merely cosmetic, as it explains the most common confusion on the subject. “Ad valorem” does not refer to a single insurance product. It is a valuation method found in two very different contexts, neither of which involves the same payer or the same legal framework.

Three concepts must be distinguished:

Carrier liability is a legal obligation, not an insurance policy you purchase. The Carrier presumed liable for loss or damage occurring between pickup and delivery, but its liability is capped based on weight and subject to certain exemptions.

The “declared value” option offered by the Carrier the compensation limit in exchange for an additional fee. It remains within the Carrier’s liability limits.

Third-party ad valorem insurance, purchased from an insurer or an independent broker, is a type of property insurance. It provides compensation for property damage based on the insured value, without the need to establish the Carrier liability. This type of insurance is commonly referred to as “ad valorem insurance.”

Declared Value or Ad Valorem Insurance: The Crucial Distinction

This is the key point where most unpleasant surprises in claims management arise, and it deserves to be clearly stated.

The declaration of value, provided for under each mode of transport (Article 24 of the CMR Convention for international road transport, the general standard contract for domestic transport in France), allows the shipper to declare a value exceeding the Limit in exchange for an agreed-upon surcharge. The declared value then replaces the statutory Limit.

But it does not change the nature of the policy. It remains subject to the same grounds for Carrier exemption, the same category exclusions in its general terms and conditions, and the same claim deadlines. In other words: if the Carrier , a declared value of €5,000 will not get you anything. It raises the Limit; it does not guarantee compensation.

All-risk insurance works the other way around: it covers damage to the goods, regardless of the Carrier liability. It therefore applies in situations where the Carrier legally exempt from liability.

⚖️ Declared Value vs. Third-Party Ad Valorem Insurance

Criterion Declared Value Option Third-Party Ad Valorem (Claisy)
Legal Status Extension of Liability Property Insurance, Stand-Alone
Compensation basis Declared Value ( Carrier Plan) Insured Amount Under the Policy
Conditions for Compensation Proven Liability Property damage covered under the policy
Carrier Exemptions Enforceable (Possible Exemption) Not enforceable against the insured
Category Exclusions Carrier Terms and Conditions Carrier Exclusions: Luxury/Art) Those in the insurance contract (Broader)
Sinister Contact Person The Carrier Slow) The Insurer / Claisy (Rapide)

When should you get it, and when is it useless?

There is only one criterion, and it takes just one minute to calculate: the value-to-weight ratio.

Compare the maximum compensation you would receive (weight in kilograms multiplied by the Limit mode of transportation) to the actual value of the shipment.

As long as the two amounts are close, the statutory coverage is sufficient, and ad valorem insurance offers no added benefit. This is the case for bulky goods with a low unit value: building materials, mass-produced furniture, and common industrial parts. It’s important to state this explicitly, because most information on the subject implies that you should always purchase additional insurance. That’s not true, and it’s an unnecessary expense.

As soon as the actual value significantly exceeds the maximum indemnity, the difference becomes a net loss for each claim, and the coverage is justified. Specifically, this applies to:

  • e-commerce for high-value-per-unit goods
  • watchmaking, jewelry, and luxury leather goods
  • High-tech and electronics
  • art, antiques, and collectibles
  • wines and spirits
  • sensitive equipment and urgent shipments where the cost of keeping them idle is higher than the value of the goods themselves
  • multimodal shipments, where responsibility is spread among successive parties involved

These categories often present two challenges: a high value-to-weight ratio, and classification as “valuable goods” in carriers’ terms and conditions, which either excludes them or sets a very low coverage limit.

How does the coverage work?

The process consists of four steps.

Declaration of value prior to handing over the shipment to Carrier. Insurance must be purchased before the goods are picked up. Once the shipment has been handed over, the risk has taken effect and can no longer be covered retroactively.

The basis of compensation. This is the most important clause in the contract—even more so than the Limit . It determines what you will actually receive: purchase price, replacement value, agreed-upon value (agreed upon in advance with the insurer, which avoids any disputes after a claim), or retail price for a retailer.

Supporting documentation. Purchase or sales invoice, shipping manifest, specific reservations noted on the manifest in the event of visible damage, and photographs of the item and its packaging. Proof of value is a prerequisite for compensation, and its absence is a common reason for denial.

Subrogation. The insurer that compensates you is subrogated to your rights and may then seek recourse against the Carrier. That is why it is your responsibility to preserve this right of recourse: file a claim upon delivery and send a substantiated complaint to Carrier three days of receipt, excluding holidays, in accordance with Article L.133-3 of the Commercial Code. This deadline applies to the claim against the Carrier the deadline for reporting the claim to your insurer is separate and is specified in your policy.

How does this differ from the Carrier 's liability Carrier

Carrier liability Carrier presumed: it is up to the Carrier to prove that it is not liable, not up to you to prove its fault. However, liability is capped based on weight, regardless of the value of the goods.

🚛 Statutory Limits by mode of transportation

Mode of transportation Applicable Rules Limit
🚚 National Highway (FR) General Standard Contract < 3 t : 33 €/kg (max 1 000 €/colis) / ≥ 3 t : 20 €/kg
🌍 International Truck Driver CMR Convention 8.33 SDR/kg (approx. 10 €/kg)
✈️ International Air Travel Montreal Convention 26 DTS/kg (approx. 31 to 33 €/kg)
🚢 Maritime The Hague-Visby Rules 666.67 SDR per package or 2 SDR per kg
🚂 Rail CIM (COTIF) Rules 17 DTS/kg (approx. 21 €/kg)

The SDR (Special Drawing Right) is a unit of account used by the International Monetary Fund, and its value fluctuates. Only amounts expressed in SDRs are authoritative; euro equivalents are for informational purposes only. A useful clarification, often misreported: the cargo liability limit under the Montreal Convention increased from 22 to 26 SDRs per kilogram on December 28, 2024, as part of the quinquennial adjustment for inflation. Any content that still cites 22 SDRs/kg is outdated.

For domestic shipping within France, the general standard contract applies only in the absence of a written agreement between the parties. Express carriers and couriers publish their own terms and conditions, the Limits of which Limits and are subject to change. Check the terms and conditions of Carrier as of the date of shipment rather than relying on a generic figure.

The example that sums it all up: An €8,000 watch weighing 500 grams, shipped via international truck transport. CMR compensation: 0.5 kg × 8.33 SDRs, or approximately €5. With ad valorem insurance, compensation is based on the insured value. This discrepancy is not a contractual anomaly; it is the normal operation of transport law.

Finally, the Carrier grounds for exemption: fault on the part of the beneficiary, inherent defect in the goods, circumstances that the carrier could not avoid, missing or defective packaging, or loading performed by the shipper. These grounds account for a large portion of claims denials, and they are not enforceable in the same way against a voluntary insurer.

How much does ad valorem insurance cost?

An ad valorem premium is calculated as a percentage of the insured value, not the cost of transportation. This is what distinguishes it from carrier-based options, which are often based on a flat rate plus a proportional component, making the effective rate difficult to determine.

In the market, the rate varies depending on the insured value, the nature of the goods, the mode of transportation, the geographic region, the volume shipped, and the observed loss ratio. Carriers’ declared value options generally range from 1% to 3% of the value.

At Claisy, the rate starts at 0.75% of the declared value, with no deductible. For a package worth €1,000, the premium starts at €7.50. For a retailer €80,000 worth of merchandise per month, the monthly cost is €600.

The right way to compare plans is not to simply compare two advertised rates, but to calculate the effective rate: any flat fee, minimum premium, deductible, requirement to use Carrier premium service, and—most importantly—the actual scope of coverage. A low rate on a plan that excludes your products is worthless.

What are the exclusions and limitations?

No insurance policy covers everything, and reputable policies make that clear. Common areas to watch out for:

Underinsurance. If you declare a value lower than the actual value, compensation is limited to the declared amount, and a pro-rata rule may apply. Underinsuring is the worst possible move.

Packaging. This is the number one reason for rejection across all insurers. The package must be able to withstand normal shipping conditions: internal padding, a box suitable for the item’s dimensions and weight, and a secure seal. Take photographs of the packaging before shipping.

Excluded categories. Currency and securities, precious metals in bullion form, perishable goods, and hazardous materials are listed in virtually all contracts. Valuable goods (watches, jewelry, art) are frequently excluded or subject to coverage limits by carriers, which is precisely why specialized insurers exist.

Evidence requirements. Invoice or appraisal to establish value; specific and well-founded reservations made at the time of delivery; photographs. Vague reservations such as “subject to unpacking” are weak and often unenforceable.

Deductibles, minimum premiums, and Limits per package and per shipment.

The filing deadlines, which must be compatible with your organization’s schedule, as missing them may result in a rejection.

How do I choose the right plan?

The rate is not the right factor to base your decision on. Five clauses determine the actual coverage, and you should read them before signing:

  1. The basis for compensation: appraised value, purchase price, replacement cost, or selling price.
  2. Excluded categories: Are your products specifically covered?
  3. Deductibles and minimum premium requirements, which can render coverage ineffective for small amounts.
  4. The Limit package and per shipment, which should be compared to your maximum shipment value.
  5. Reporting deadlines and how they align with your logistics operations.

For professionals, there are two additional operational criteria to consider: Carrier freedom (an independent insurance policy allows you to keep your existing transport contracts) and the claims settlement time, which determines how much cash is tied up for each claim.

If your shipments fall into these categories, you can review the details of our ad valorem package insurance or calculate your premium directly.

❓ Frequently Asked Questions: Ad Valorem Insurance

⚖️ What is ad valorem insurance?
“Ad valorem” means “based on value.” The term refers to a basis for valuation: compensation calculated based on the declared value of the goods rather than their weight. In practice, ad valorem insurance refers to property insurance purchased from a third party, which provides compensation based on the insured value, regardless of the Carrier limited liability.
↔️ What is the difference between declared value and ad valorem?
Declaring the value to Carrier the Limit but remains subject to the Carrier liability framework Carrier the same grounds for exemption, the same exclusions, and the same long waiting periods. Third-party ad valorem insurance (such as Claisy) is property insurance: it compensates for damage up to the insured value, even when the Carrier legally exempt from liability.
📑 Is ad valorem insurance required?
No. It is optional. What is required is the Carrier professional liability insurance. However, coverage for the actual value of your goods against loss or theft is provided by a separate insurance policy, which is strongly recommended for any valuable shipment.
📉 What is the minimum amount required to purchase it?
The criterion is the value-to-weight ratio: compare the Carrier maximum compensation Carrier e.g., €23/kg) to the actual value of the item. As long as the amounts are similar, the statutory coverage is sufficient. As soon as the gap widens (e.g., a 100-gram piece of jewelry worth €1,000), ad valorem coverage is essential.
🧮 How is the premium calculated?
The premium is calculated by applying a rate to the declared value. At Claisy, this rate ranges from 0.60% to 0.75%, with no deductible. By way of comparison, insurance options offered directly by carriers generally range from 1% to 3% of the value.
🛡️ What exactly does it cover?
A general cargo insurance policy typically covers loss, theft, breakage, and damage based on the insured value. Common exclusions include defective packaging, under-declaration, and certain prohibited goods. Claisy covers sensitive goods such as jewelry and electronics, which are often excluded by other insurers.
🚀 Is this useful for e-commerce?
Yes, because e-commerce products often have a high value-to-weight ratio. The legal compensation system pays per kilogram, which leaves a huge financial gap in the event of the loss of a smartphone, a watch, or a brand-name garment.
🚫 Can I insure a package that has already been shipped?
No. The insurance must be purchased before the goods are handed over to Carrier or, at the latest, on the same day before 6:00 a.m. the following day). Once the package is in transit, the risk has already begun and cannot be covered retroactively.
