FOB vs CIF: Key Differences for UK Importers

Key Takeaways

FOB (Free on Board) means the buyer arranges and pays for ocean freight, insurance, and destination costs — giving full control over the shipping process
CIF (Cost, Insurance and Freight) means the seller arranges and pays for freight and basic insurance to the destination port — but risk still transfers to the buyer once goods are loaded at origin
Both terms apply exclusively to sea and inland waterway transport; for containerised or multimodal shipments, consider FCA or CIP instead
UK importers using FOB typically achieve lower total landed costs on regular, high-volume shipments because they can negotiate freight rates directly
The Incoterm you choose directly affects your customs valuation, duty liability, and insurance coverage — getting it wrong costs money

What Is FOB (Free on Board)?

FOB is one of the 11 Incoterms 2020 rules published by the International Chamber of Commerce (ICC). It applies exclusively to sea and inland waterway transport.

Under FOB, the seller is responsible for:

Manufacturing or sourcing the goods and preparing them for export
Transporting goods to the named port of shipment (e.g., FOB Shanghai)
Loading goods on board the vessel nominated by the buyer
Export customs clearance — including all documentation and any export duties

Once the goods pass over the ship’s rail at the port of origin, everything transfers to the buyer. From that point, the buyer is responsible for:

Ocean freight from the origin port to the UK destination port
Marine cargo insurance for the transit
UK import customs clearance, including the customs declaration, import duties, and import VAT
Unloading, port charges, and inland delivery to the final destination

The critical point: under FOB, the buyer controls the shipping. You choose the carrier, negotiate the rate, select the route, and arrange insurance to your own standards. The seller’s job ends when goods are on the vessel.

What Is CIF (Cost, Insurance and Freight)?

CIF shares the same origin obligations as FOB — the seller handles everything up to and including loading goods on board the vessel. The difference is what happens next.

Under CIF, the seller also arranges and pays for:

Ocean freight to the named destination port (e.g., CIF Felixstowe)
Marine cargo insurance — but only to the minimum cover level required by ICC Clause C, which covers major perils only (not all risks)

The buyer remains responsible for:

UK import customs clearance, duties, and import VAT
Unloading charges at the destination port (unless included in the freight contract)
Inland transport from the port to the final destination
Any additional insurance beyond the minimum cover the seller provides

Here is the part that catches people out: despite the seller paying for freight and insurance, risk transfers to the buyer at the port of origin — the same transfer point as FOB. If goods are damaged during the ocean crossing, it is the buyer’s problem. The seller’s insurance obligation is a cost arrangement, not a risk arrangement.

This means the seller could arrange the cheapest possible freight route and the most basic insurance policy. If something goes wrong, you file the claim — on a policy you did not choose, with cover you may find inadequate.

FOB vs CIF: Side-by-Side Comparison

Factor	FOB	CIF
Full name	Free on Board	Cost, Insurance and Freight
Applicable transport	Sea and inland waterway only	Sea and inland waterway only
Freight cost paid by	Buyer	Seller
Insurance arranged by	Buyer	Seller (minimum cover only)
Risk transfer point	When goods are loaded on vessel at origin	When goods are loaded on vessel at origin
Export clearance	Seller	Seller
Import clearance	Buyer	Buyer
Buyer controls carrier?	Yes	No
Buyer controls insurance?	Yes	No (unless additional cover arranged)
Named location	Port of shipment (origin)	Port of destination
Customs value basis	FOB value (goods + origin costs)	CIF value (goods + freight + insurance)

The risk transfer point is identical. This is the single most important thing to understand. CIF does not mean the seller carries the risk further — it means they pay for more, while you still bear the risk from the same moment.

Cost Implications for UK Buyers

Freight Costs

Under CIF, the freight cost is bundled into the price you pay the seller. This looks simpler on paper, but you lose visibility. The seller may mark up the freight, choose a slower or less reliable carrier, or route goods through additional transhipment ports to reduce their own costs.

Under FOB, you negotiate directly with shipping lines or freight forwarders. If you ship regularly, you can secure volume-based rates, choose preferred carriers, and optimise routing. For a UK importer bringing in multiple containers per month, the savings add up quickly.

Insurance Costs

CIF requires the seller to provide minimum insurance cover under ICC Clause C. This covers major casualties — sinking, fire, collision — but excludes risks such as theft, pilferage, water damage from rough seas, and damage during loading or discharge. Many UK importers find this insufficient.

Under FOB, you arrange your own marine cargo insurance. You can select ICC Clause A (all-risks cover), add war and strikes clauses, and tailor the policy to your cargo type and value. The cost is often comparable or lower than the hidden insurance premium embedded in a CIF price — and the cover is substantially better.

Total Landed Cost

Your total landed cost includes the goods price, freight, insurance, import duty, import VAT, port handling, and inland delivery. Under CIF, the first three are bundled together. Under FOB, they are separated.

Separating these elements gives you more control, better visibility, and more opportunities to reduce costs across each component.

When to Use FOB

FOB is generally the stronger choice for UK importers in these situations:

Regular, volume shipments — if you import consistently, you can negotiate competitive freight rates and build relationships with reliable carriers
High-value or fragile goods — you want full control over insurance cover, carrier selection, and handling requirements
Time-sensitive supply chains — choosing your own carrier means you control transit times, routing, and vessel schedules
Multiple suppliers shipping from the same region — you can consolidate shipments from different suppliers into fewer containers, reducing per-unit freight costs
When you have a trusted freight forwarder — a good UK-based forwarder will handle the shipping leg efficiently and give you end-to-end visibility

FOB requires more hands-on management. You need a freight forwarder, a relationship with carriers (or your forwarder manages this), and you must arrange insurance. But this operational involvement is precisely what gives you cost control and supply chain visibility.

When to Use CIF

CIF makes sense in specific circumstances:

Infrequent or one-off shipments — if you import occasionally, the administrative overhead of arranging freight and insurance may not justify the savings
Low-value goods with standard shipping requirements — when the margin between CIF and FOB savings is negligible, simplicity wins
When the seller has significantly better freight rates — some large manufacturers ship in such volume that their freight rates are genuinely lower than what you could achieve; this is worth verifying rather than assuming
New supplier relationships — CIF can simplify initial orders while you establish the commercial relationship, before transitioning to FOB as volumes grow
When you lack logistics infrastructure — if you do not yet have a freight forwarder or the internal capability to manage international shipping, CIF removes that burden

Even when using CIF, consider arranging your own supplementary insurance. The minimum cover provided under CIF is rarely adequate for anything beyond bulk commodities with low per-unit value.

Impact on Customs Valuation

This is where the choice between FOB and CIF has a direct financial consequence beyond the commercial price.

When goods arrive in the UK, HMRC assesses import duty based on the customs value of the goods. The UK uses the CIF method for customs valuation. This means:

If you buy CIF, the invoice price already includes freight and insurance. This is your customs value (subject to adjustments). The duty is calculated on this higher amount.
If you buy FOB, you must add the freight and insurance costs to the FOB price to arrive at the CIF value for customs purposes. You declare these costs separately on the customs declaration.

In both cases, duty is calculated on the CIF value. However, under FOB, you have transparency over exactly what freight and insurance figures are declared. Under CIF, the combined price may include seller mark-ups on freight that inflate your customs value — and therefore your duty bill.

For goods with high duty rates, this difference matters. If your goods attract a 12% tariff and the seller has added a 15% mark-up on the freight element within a CIF price, you are paying duty on that mark-up. Under FOB, you declare the actual freight cost.

Understanding how commodity codes and tariff rates apply to your goods helps you quantify this impact accurately.

Practical Tips for UK Importers

Ask for both prices. Request FOB and CIF quotes from your supplier. Compare the CIF price against the FOB price plus your own freight and insurance costs. The difference reveals the seller’s mark-up on logistics.
Check the insurance clause. If buying CIF, ask the seller for the insurance certificate and confirm whether it is ICC Clause A, B, or C. If it is Clause C, arrange top-up cover independently.
Factor in the full chain. Neither FOB nor CIF covers UK port handling, customs clearance fees, or inland delivery. Budget for these separately regardless of which term you use.
Consider FCA for containers. If your goods are containerised and handed to the carrier at an inland point (such as the supplier’s factory), FOB is technically incorrect — risk should transfer at the point of delivery to the carrier, not the ship’s rail. FCA (Free Carrier) is the correct term for this scenario. See our Incoterms guide for the full breakdown.
Document everything. Whichever term you use, ensure your purchase order, commercial invoice, and bill of lading all reference the same Incoterm and named location. Inconsistencies cause delays at customs clearance.

Frequently Asked Questions

Is FOB or CIF better for UK importers?

For most regular importers, FOB is the better choice. It gives you control over carrier selection, freight costs, insurance cover, and transit routing. CIF is simpler but trades that control for convenience — and often costs more overall once you account for the seller’s freight mark-up and inadequate insurance cover.

Does risk transfer differently under FOB and CIF?

No. Under both FOB and CIF, risk transfers from seller to buyer when goods are loaded on board the vessel at the port of origin. The common misconception is that CIF means the seller carries risk to the destination — it does not. The seller pays for freight and insurance to the destination, but risk passes at origin.

How does FOB vs CIF affect my import duty?

UK customs duty is calculated on the CIF value of goods — that is, the cost of goods plus freight and insurance. Under CIF, this is your invoice price. Under FOB, you add the actual freight and insurance to the goods price. If a CIF seller has inflated the freight element, you pay duty on that inflated amount. FOB gives you transparency and potentially a lower duty base. See our import duty guide for the full calculation method.

Can I use FOB or CIF for air freight?

No. Both FOB and CIF apply exclusively to sea and inland waterway transport. For air freight, road, or multimodal shipments, use FCA (Free Carrier) instead of FOB, and CIP (Carriage and Insurance Paid To) instead of CIF. These terms work identically in principle but apply to any transport mode. Our Incoterms guide covers all 11 terms.

What insurance does the seller provide under CIF?

The seller must arrange marine cargo insurance at minimum ICC Clause C level, covering the CIF value plus 10%. Clause C is basic cover — it includes total loss from major casualties (fire, sinking, collision) but excludes theft, pilferage, water damage, and many other common risks. If your cargo needs broader protection, you should either negotiate ICC Clause A cover with the seller or arrange your own supplementary policy.
