Duty & Taxes Coverage: Marine Cargo Policy UK

Why Duty and Taxes Create a Coverage Gap

Under a standard Institute Cargo Clauses (A), (B) or (C) placement, the insured value is typically the CIF value of the goods plus an agreed percentage to cover anticipated profit. That uplift is a commercial convention, not a statutory requirement, and it does not automatically capture import duty or VAT. If your goods are destroyed after customs clearance — or if duty has been paid prior to delivery and the cargo is subsequently lost — you are holding a fiscal liability that your policy may not reimburse.

The problem is compounded by the point-in-time question. Duty becomes a concrete financial exposure the moment it is paid or legally committed. A cargo that is damaged in a UK bonded warehouse before duty is assessed sits in a different position from one that clears customs and is then destroyed in a road transit leg. Your policy needs to address both scenarios explicitly, and the sum insured needs to reflect the duty-inclusive value at the relevant stage of the journey.

Freight forwarders acting as principals on a consolidated shipment face an additional layer of risk: they may have paid duty on behalf of multiple cargo owners and hold a recovery exposure that is not their own commercial stock. If you are operating in that capacity, your cargo liability wording and your own cargo policy need to be read together, not in isolation.

How the Institute Cargo Clauses Treat Insured Value

The Institute Cargo Clauses (A), (B) and (C) are silent on the composition of the insured value — they do not prescribe what must be included. That is deliberate: the clauses govern the perils covered and the exclusions that apply, not the arithmetic of your sum insured. It is therefore entirely possible to write a policy on Clause A (the broadest all-risks basis) and still be underinsured for duty if you have not declared it.

The standard market practice is to insure on CIF plus a percentage. If you have paid or are committed to pay import duty, VAT or excise, those amounts should be added to the insured value at the appropriate stage. Some underwriters will accept a single blended sum insured that rolls up invoice value, freight, insurance and duty into one figure. Others prefer a separate duty extension or endorsement that activates only when duty has been formally assessed or paid. Ask your broker which basis the underwriter is quoting on — the distinction matters at claim time.

Under the Hague-Visby Rules, the carrier's liability for loss or damage is capped at a relatively low per-package or per-kilo limit. That cap does not include duty. If you are relying on a carrier's liability to recover duty costs, you will almost certainly be disappointed. Your own cargo policy is the correct instrument for this exposure, not a claim against the bill of lading carrier.

Sue-and-labour provisions in your policy require you to take reasonable steps to minimise loss. If a damaged shipment can be re-exported to avoid duty, or if a duty drawback claim is available, your insurer may expect you to pursue it. Failing to do so could reduce your recovery. Make sure your operations team understands this obligation before a loss occurs, not after.

What Is Typically Covered — and What Is Not

Specialist underwriters in the London company market will generally extend cover to include irrecoverable import duty and VAT where those amounts have been paid and the underlying goods are lost or damaged by an insured peril. The extension is not automatic: it requires either a specific endorsement or a policy wording that explicitly includes fiscal charges in the definition of insured value.

Excise duty on goods such as alcohol, tobacco and hydrocarbon fuels is treated with more caution. Underwriters will want to know the commodity, the duty rate, the transit route and the bonding arrangements before they agree to include excise in the sum insured. High-duty commodities attract higher rates and sometimes sub-limits.

Anti-dumping duties, countervailing duties and tariff surcharges imposed after the policy inception date are generally not covered. These are regulatory or political impositions, not losses flowing from a physical peril. Similarly, fines and penalties levied by HMRC for customs irregularities fall outside the scope of a cargo policy regardless of how the wording is structured.

• Typically covered (subject to endorsement): import duty paid prior to loss, irrecoverable VAT on destroyed goods, customs examination fees where loss is confirmed
• Typically covered: duty on goods damaged in a bonded warehouse by an insured peril (fire, flood, theft under Clause A)
• Typically excluded: duty on goods confiscated or detained by customs authorities
• Typically excluded: anti-dumping or countervailing duties imposed post-shipment
• Typically excluded: HMRC fines, penalties or interest charges
• Typically excluded: duty on goods that are undamaged but commercially unsaleable due to market conditions

Structuring Your Sum Insured Correctly

The single most practical step you can take is to calculate your worst-case duty exposure per shipment and confirm that it is captured in the declared value. For most UK importers, this means taking the CIF value, adding the applicable duty rate and VAT, and using that total as the insured value. If your duty rate varies by commodity code or country of origin, apply the highest applicable rate to avoid a shortfall.

For open cover or annual floating policies — the most common structure for regular shippers — the maximum any one conveyance (MAOC) limit needs to reflect the duty-inclusive value of the largest single shipment you move. If your MAOC was set two years ago and duty rates have changed, or if you have moved into higher-duty commodity categories, your limit may be stale. Review it at renewal and after any significant change in your import profile.

General average is a separate but related exposure. Under the York-Antwerp Rules, cargo owners are required to contribute to a general average fund in proportion to the salved value of their goods. That contribution is calculated on the arrived value of the cargo, which in most jurisdictions includes duty paid. If your policy does not include a general average clause that covers duty-inclusive values, your out-of-pocket contribution could exceed your recovery.

Post-Brexit, goods moving between Great Britain and the EU — or transiting through Northern Ireland — face additional customs complexity. Duty suspension regimes, customs warehousing and inward processing relief all affect when duty crystallises as a financial exposure. If your supply chain uses any of these regimes, make sure your broker understands the bonding arrangements and has confirmed with the underwriter how the policy responds at each stage.

What to Bring When Requesting a Quote

Underwriters need enough information to assess the duty exposure before they can confirm whether to include it and on what terms. A vague request for 'duty cover' will produce a vague quotation. Come to your broker with specifics.

The more precisely you can describe the duty structure of your shipments, the faster and more accurately your broker can negotiate the endorsement wording with the underwriter. Ambiguity at placement becomes a dispute at claim time.

• Commodity description and HS tariff codes for the goods you are importing
• Country of origin and country of export (affects applicable duty rates and trade agreements)
• Whether duty is paid pre-clearance, post-clearance or under a deferment account
• Whether goods move through a bonded warehouse or under customs warehousing arrangements
• Your annual import volume and the value of the largest single shipment
• Any existing duty suspension or relief schemes you operate under
• Claims history for the past three to five years, including any duty-related losses

Renewal Considerations and Market Conditions

At renewal, your broker should be asking the underwriter to confirm that the duty extension wording has not been narrowed by a general policy revision. Market wordings do change, and a clause that responded broadly at last renewal may have been tightened. Request a marked-up comparison of any wording changes before you sign the renewal slip.

Capacity for high-duty commodities — particularly alcohol, tobacco and electronics — has tightened in parts of the specialist market. If your commodity mix has shifted toward higher-duty categories, expect underwriters to ask more detailed questions about your security arrangements, bonded storage and transit controls. Demonstrating robust supply chain governance will support your negotiating position.

If you have had a duty-related claim in the past three years, be prepared to explain the circumstances and what procedural changes you have made. Underwriters will want to understand whether the loss was a one-off event or a systemic vulnerability. A clear, factual account presented by your broker before the underwriter asks for it is always more effective than a reactive response.

Frequently asked questions

Do I need a separate policy to cover import duty, or can it be added to my existing cargo cover?

In most cases it can be added to your existing marine cargo policy as an endorsement or by adjusting the declared sum insured to include duty. A standalone duty policy is rarely necessary unless your duty exposure is very large relative to the underlying cargo value, or the commodity falls into a category that standard cargo underwriters decline to cover on a duty-inclusive basis.

What happens if I pay duty under a deferment account and the goods are lost before the deferment payment falls due?

The duty is still legally owed to HMRC regardless of whether the goods survive. Your policy needs to respond to the irrecoverable duty liability, not just the physical loss of the goods. Confirm with your broker that the policy wording covers committed but not yet paid duty, not only duty already disbursed.

Does my cargo policy cover VAT on the lost goods as well as import duty?

It can, but only if VAT is included in the insured value or the policy wording explicitly extends to it. In practice, VAT-registered businesses can often reclaim input VAT through their VAT return even on destroyed goods, which reduces the net exposure. Your broker should confirm your VAT recovery position with you before deciding whether to include VAT in the sum insured, to avoid over-insuring.

What do you need from me to get a quote that includes duty cover?

At minimum: a description of the goods and their HS tariff codes, the countries of origin and export, the applicable duty rates, your annual import value, the maximum value of any single shipment, details of any bonded warehouse or customs warehousing arrangements, and your claims history for the past three to five years. The more precisely you can describe your duty structure, the more accurately we can negotiate the endorsement terms.

How long does it take to bind a cargo policy with a duty extension?

For straightforward commodities with a clear duty structure, a specialist underwriter can typically confirm terms within a few working days of receiving a complete submission. High-duty or restricted commodities — alcohol, tobacco, electronics — may require additional underwriting review and take longer. If you have a shipment moving imminently, tell your broker the cargo-ready date at the outset so they can prioritise accordingly.

If the carrier is liable for the loss, can I still claim duty costs from my own insurer?

Yes, subject to your policy wording. Your insurer will pay your claim and then pursue the carrier by way of subrogation. The carrier's liability under Hague-Visby is capped at a low per-package or per-kilo limit that will rarely cover duty in full, which is precisely why your own cargo policy — not the bill of lading — is the right instrument for this exposure. Cooperate fully with your insurer's subrogation efforts as required by your policy conditions.
