Reading the First Quote — What CIF and FOB Hide

For context: where else can you get this

GOV.UK explains that UK customs values goods on a CIF basis — but does not tell you how to audit the CIF figure your supplier quoted. Freight forwarder blogs define Incoterms from the logistics side, not the buyer's quote-reading side. Alibaba platform guides say "compare FOB prices" without explaining how to estimate a fair FOB baseline or benchmark the freight component. This article gives the buyer a quantitative audit method: decompose, benchmark each component against public data, and ask the supplier to verify the split.

Anatomy of a CIF quote: the five bundled components

When a supplier writes "CIF Felixstowe £45,000," that single number contains five distinct cost layers:

(a) Factory ex-works price. The cost to manufacture the goods and have them ready for collection at the factory gate. This is the supplier's actual production cost plus their manufacturing margin. It is the number closest to the "real" price of the goods.

(b) Chinese inland freight. Transport from the factory to the port of loading — typically Shanghai, Ningbo, Shenzhen, or Qingdao. This covers trucking or rail from the factory to the port, container loading, and port-side handling within China.

(c) Ocean freight. The container shipping cost from the Chinese port to Felixstowe (or whichever UK port is named). This is the largest variable component and the one most sensitive to market conditions.

(d) Marine insurance. Cover for loss or damage during transit. For standard industrial goods under All Risks cover (Institute Cargo Clauses A), the typical premium is 0.1-0.3% of CIF value, as of May 2026. The insured amount is conventionally set at 110% of CIF value — a standard practice codified in trade custom, not statute. On a £45,000 CIF order, insurance costs roughly £50-£150. It is a small line item, but a useful audit signal: if the implied insurance cost in a CIF quote is well above 0.3%, other costs are likely bundled into it.

(e) Documentation, clearance, and supplier margin. Export documentation preparation, Chinese customs clearance, and the supplier's commercial margin on the logistics bundle. In practice, this ranges from £150-£400 for documentation plus whatever margin the supplier applies. This is the least visible component and the one where trading companies most commonly embed additional margin.

What Incoterms transfer — and when they were last revised

Incoterms are published by the International Chamber of Commerce (ICC). The current edition is Incoterms 2020, published September 2019 and in force from 1 January 2020. They define who pays for what and where risk transfers between buyer and seller. The version matters because obligations changed between 2010 and 2020.

The terms most relevant to UK buyers sourcing from China:

EXW (Ex Works): buyer assumes all costs and risk from the factory gate. Rarely practical for international orders because the buyer must arrange Chinese export clearance.

FOB (Free On Board): the supplier delivers when goods are loaded on board the vessel at the named Chinese port. The buyer arranges and pays for ocean freight, insurance, and UK-side costs. Sea and inland waterway transport only.

CIF (Cost, Insurance, and Freight): risk transfers at the same point as FOB — on board the vessel at the Chinese port — but the supplier contracts and pays for ocean freight and minimum insurance to the named destination port. The minimum insurance under CIF is Institute Cargo Clauses C — named-perils cover, not all-risks.

CIP (Carriage and Insurance Paid To): similar to CIF but for any transport mode. The key change in Incoterms 2020: CIP insurance was upgraded from Institute Cargo Clauses C to Clauses A — full all-risks cover. CIF insurance was not upgraded and remains at Clauses C. This means a CIP quote should cost more than an equivalent CIF quote, because the insurance obligation is higher. If a supplier quotes CIP at the same price as CIF, either they have not applied the correct insurance level or the difference is being absorbed elsewhere.

DDP (Delivered Duty Paid): the supplier handles everything — freight, insurance, UK import duty, UK VAT, port handling, last-mile delivery. The buyer receives goods at their premises with all costs paid. This is the most bundled Incoterm: it hides not just five components but potentially ten or more.

The FOB baseline and the pound-per-kilo sanity check

You can estimate a fair FOB price independently using HMRC Overseas Trade Statistics (OTS).

HMRC publishes monthly data on non-EU imports into the UK, disaggregated by HS chapter and country of origin, including total value (in pounds) and total weight (in kilograms). The data is available at uktradeinfo.com. Dividing value by weight gives you the implied unit value in pounds per kilogram for that HS chapter from China over any period you choose.

This is not a precise price for your product. HS chapters aggregate many different goods — HS chapter 84 (machinery) includes everything from simple pumps to complex CNC machines. The blended average will not match your specific item. The purpose of this check is not to set a price. It is to flag outliers.

If the implied £/kg for HS chapter 73 (iron and steel articles) from China over the last 12 months is £2.80/kg, and your supplier's quoted FOB unit price implies £9.50/kg for standard steel brackets, the gap is a prompt. It might be entirely justified — your brackets may be precision-machined, heat-treated, and certified, which commands a premium over the chapter average. Or it might signal that the "FOB" price includes costs that should sit elsewhere. Either way, you now have a specific question to ask.

The freight cross-reference. The Drewry World Container Index (WCI) publishes weekly composite container freight rates on eight major East-West routes, priced in USD per 40-foot equivalent unit (FEU). The Shanghai-Rotterdam index is the closest proxy for China-to-UK rates. As a benchmark, the Shanghai-Rotterdam rate was $2,046/FEU as of 8 May 2026 — 46% above the pre-pandemic 2019 average of $1,420, but 80% below the September 2021 pandemic peak of $10,377.

To use this: if your order fills roughly half a 40-foot container, a reasonable freight estimate is approximately half the current WCI rate, converted to pounds at the prevailing exchange rate. If the gap between your estimated FOB and the supplier's CIF is significantly wider than freight plus insurance plus documentation, the excess is either margin or costs the supplier has not disclosed.

Why the supplier prefers CIF

The supplier locks in their margin in one number. They book freight through a preferred forwarder — often a relationship where the forwarder offers discounted rates in exchange for volume, and the supplier passes through the undiscounted rate to the buyer. They control documentation timing. None of this is fraudulent. It is standard commercial structure. But the buyer who only sees CIF cannot price-shop the freight or insurance components independently.

When you request FOB-separated pricing (as described in Issue #15's seven-line RFQ template), you flush out this structure. A factory confident in its production cost will quote FOB readily. A trading company that earns margin primarily on the logistics spread may resist splitting the number — which is itself informative.

Gatekeeper view: what is visible from China-side

The supplier's internal quoting process typically works like this: the sales manager starts with the factory's ex-works cost, adds a sales margin (set by the sales manager or the company's pricing policy), then requests a freight quote from a partner forwarder. The forwarder relationship often produces a rate 5-15% below what the forwarder would quote an outside buyer — but the sales manager passes through a higher number to the buyer, capturing the spread as additional margin. This is invisible on the CIF figure.

The internal quoting screen shows each layer separately: EXW, inland freight, ocean freight, insurance, documentation. The buyer's quote shows one number. The FOB figure, when you can get it, strips away the logistics layers and sits closer to the factory's actual cost. Everything above FOB is layer-by-layer commercial structure that is transparent inside the supplier's system but opaque in the issued quote.

This is why requesting FOB-separated pricing is not aggressive — it is asking the supplier to show you what they already see on their own screen.

Where this framework breaks

Highly customised products with no OTS comparator. If your product is niche enough that the HS chapter blended average is dominated by dissimilar goods, the £/kg sanity check gives a misleading signal. The gap between your quote and the average reflects product difference, not price inflation. For these products, request FOB-separated pricing and benchmark the freight and insurance components independently — the production-cost component cannot be sanity-checked against aggregate data.

Very small orders where freight is disproportionate. On shipments under 1 cubic metre (CBM), ocean freight is typically an LCL (Less than Container Load) consolidation charge. LCL pricing follows a different structure — per-CBM minimums, consolidation surcharges, warehouse handling — that does not track container-rate indices like Drewry WCI. The freight benchmark becomes unreliable for small shipments.

Airfreight quotes. The five-component decomposition assumes ocean freight. Air cargo uses volumetric weight pricing, fuel surcharges, and airport handling fees that require different benchmarks. If the supplier quoted air freight, adjust the model accordingly.

DDP quotes. If the supplier quoted DDP (Delivered Duty Paid), the bundle includes UK-side costs — import duty, UK VAT, port handling, last-mile delivery — on top of the five CIF components. The decomposition model needs to be extended, not abandoned.

Quotes older than 30 days in volatile freight markets. Freight indices move weekly. A quote issued six weeks ago may have been fair at issuance but look inflated against current rates. Always benchmark the freight component against the index reading on or near the quote date, not today's rate.

Trends layer

As of May 2026, Asia-to-Europe container freight rates remain more volatile than the pre-2020 baseline, with the Drewry WCI showing sustained fluctuation above historical norms. This makes the freight component of CIF quotes harder to assess without a current index reference. The method in this article — checking the supplier's implied freight charge against the WCI or Freightos FBX on the quote date — is more important now than when rates were stable and predictable. A CIF quote accepted without freight benchmarking during a rate spike locks in inflated logistics costs for the duration of the order.

Coming up

Issue #18 takes three quotes for the same product and compares them line by line using the decomposition method from this issue — showing why the cheapest headline CIF number is not always the cheapest landed cost.

Issue #19 moves to payment terms: T/T 30/70 versus L/C versus Trade Assurance, and what each structure actually costs.
