How to Read a Freight Quote: Fee Lines Explained Without Prices
A structural guide to ocean and air quotes: how to classify each fee line by its unit of count, spot basis mismatches, and audit a quote before you accept it.
Two quotes for the same cargo can differ by half their totals while both look "competitive," because a freight quote is not one price — it is a stack of separately priced fee lines, each with its own unit of count, its own payer, and its own moment in the journey. This guide deliberately explains structure rather than prices: once you can classify every line on any quote, price comparisons become arithmetic instead of guesswork.
The first question: what quantity is being priced?
Every chargeable line on a quote is priced against one of five units of count, and misreading the unit is the root of most comparison errors:
2. per chargeable kg — air & express lines: bill on MAX(gross, volumetric)
3. per shipment (flat) — documentation, booking, export declaration entries
4. per container — FCL terminal handling, container cleaning, seal
5. per day / per document — demurrage, detention, per-B/L telex releases
Before comparing two numbers, confirm they price the same unit. A "handling" line at a flat sum is not comparable to a "handling" line per CBM until you multiply each by your own consignment size — compute your chargeable quantity first with the CBM calculator, then hold every quote line against that one number.
The geography test: origin, freight, destination, duty
Sort every line into the leg where it physically happens. Origin charges — terminal handling, documentation fee, VGM (verified gross mass) declaration, seal — occur at the departure port and are often billed in the origin currency. Freight properis the line-haul itself. Destination charges — destination terminal handling, the LCL deconsolidation and handling at the container freight station, customs brokerage entry, ISPS security — occur where the goods arrive, are billed in the destination currency, and are the classic home of the "surprise invoice": a quote that shows only freight plus origin costs is honest but incomplete, and the omitted leg is usually the expensive one. Duty and import taxes are not freight at all; they are assessed by customs on a statutory base that depends on your destination (transaction value in the US, CIF in the EU and UK, customs value in Australia) — our duty & landed cost estimator models those bases.
An Incoterm, read correctly, is simply a pre-agreed map of this geography: it states which of those four buckets the seller's price already covers. Run your term through the Incoterms 2020 comparison tool and check the cost-column against the quote's leg list — if the term says the buyer owns destination charges, the quote should be showing them as your lines, not hiding them.
Surcharges: percentage, flat, and floating lines
Surcharge lines exist because carrier costs float between contract renewals, and they come in three forms you should distinguish. Floating-adjustment surcharges (bunker adjustment, low-sulfur fuel, congestion) recalculate periodically against published indexes — ask which index and how often. Peak-season and security surcharges are dated: check the validity window printed on the quote, because a rate valid for a week is a different instrument from one valid for a quarter. Currency-adjustment factorsapply when the billing currency differs from the carrier's cost currency. None of these are dishonest; all of them are incomparable across quotes unless you normalize each quote to the same all-in unit cost — total charges divided by your chargeable quantity.
Free time, demurrage, detention — the clock lines
Quotes also allocate time. Free time is the grace period the container may sit at the terminal (that is where demurrage begins) or stay with you before returning (that is where detention begins) before per-day charges start. Demurrage is charged by the terminal for occupied yard space; detention is charged by the shipping line for the equipment being out of their control. On LCL the analogous window runs at the CFS warehouse, and storage there commonly starts earlier than importers expect because deconsolidation queues are measured in days, not hours. A quote that omits free-time terms entirely is asking you to accept an unpriced option.
The eight-point audit before you accept any quote
(1) Does the pricing basis — CBM, revenue ton, or chargeable kg — match your own computed quantity? (2) Which legs does the total actually include — origin, line-haul, destination, or all three? (3) Is every fee line stated with its unit of count? (4) Is the quote's validity window long enough for your production timeline? (5) Are surcharges itemized with their adjustment mechanism? (6) Are free-time terms stated for demurrage and detention? (7) Does the Incoterm in the sale contract agree with who the quote says pays each leg? (8) Is the currency per line stated, so you can apply one exchange rate consistently — with our exchange rate converter if the billing and settlement currencies differ?
Quotes that pass all eight points can be compared by a single number: all-in cost per chargeable unit. Quotes that fail any point are not expensive or cheap — they are undefined, and an undefined number cannot be compared at all. Ask the missing line back before signing; the structure of a freight quote is public knowledge, and every serious counterparty can fill it in.
