FOB vs CIF for bulk ore: differences, costs included and how to convert

Under FOB the seller loads the ore on the buyer's ship and the buyer pays the sea freight and any insurance. Under CIF the seller also pays the sea freight to the destination port and buys minimum insurance for the buyer. A CIF price is therefore the FOB price plus freight, insurance and any other costs the seller carries. Risk passes to the buyer at the load port in both. As an illustration, FOB $170 plus $35 freight and 0.15% insurance on 110% of value gives CIF of about $205.34 per tonne.

Based on the usual allocation under Incoterms 2020. The "other costs" row is not set by the Incoterm: a seller can price in whatever it chooses, so ask what a CIF price contains.

Worked example: estimating CIF from FOB
ItemPer tonne
FOB price$170.00
+ Sea freight$35.00
+ Other seller costs$0.00
+ Insurance premium (0.15% of 110% of the CIF value)$0.34
= CIF price$205.34

Illustrative rates, not quotes. The premium is charged on the CIF value, so it is solved together with the price. Use the calculator with a current freight quote.

The difference in one sentence

FOB (free on board) means the seller delivers the ore on board the ship the buyer has arranged, and the buyer pays for the main carriage. CIF (cost, insurance and freight) means the seller arranges and pays for the sea freight to the destination port and buys minimum insurance. In both, the risk of loss or damage passes to the buyer once the cargo is on board at the port of shipment.

How to estimate a CIF price from a FOB price

Add the sea freight, any other costs the seller carries to the destination port, and the insurance premium. Marine insurance for CIF is commonly written on 110% of the contract value, and the minimum cover under Incoterms 2020 is the Institute Cargo Clauses (C). Because the premium is a percentage of the CIF value, CIF equals the FOB price plus freight and other costs, divided by one minus the insured percentage times the premium rate.

The freight is the big number and the one that moves. It depends on the route, the size of ship, the fuel price and the state of the freight market, so use a current quote from a broker for the route from your loading port to the destination port instead of a rule of thumb. The FOB to CIF calculator on this site does the arithmetic and shows each cost.

What a CIF price does not include

Unloading at the destination port is normally for the buyer unless the freight contract includes it. Import duties, taxes and inland transport from the port are also for the buyer. And because the insurance is minimum cover, a buyer may want broader cover at its own cost.

Which to choose

  • A buyer with its own shipping desk and cargo insurance often prefers FOB, because it controls the ship, the timing and the cover.
  • A buyer who wants one delivered price, or wants to compare offers against a CIF benchmark such as high-grade manganese ore CIF Tianjin, may prefer CIF.
  • A seller offering CIF takes the freight market risk between quoting and fixing the ship, so it should price in a margin or fix the freight when it agrees the sale.
  • Whatever the rule, compare offers on the same basis by converting them to FOB or to CIF, and write the rule, the port and the Incoterms edition in the contract.

Frequently asked questions

What costs are included in a CIF price?

The FOB price, which covers the ore, inland transport to the port, export clearance and loading on board, plus sea freight and minimum marine insurance. A seller may add other costs of its own.

How do I estimate a CIF price from FOB?

Add the sea freight, any other seller costs and the insurance premium. The insurance premium is charged on the CIF value, so the calculation solves for it together with the price.

Who pays unloading costs under CIF?

Normally the buyer, unless the contract of carriage includes unloading. Check the freight contract and the sales contract.
