Ask three forwarders for a quote on the same shipment and you get three documents that cannot be compared without rewriting them. One is port to port, one is door to door, one quotes an all-in rate that excludes destination charges. Here is how to normalize them before deciding.
Write down the four segments and mark which are included in each quote.
| Segment | Question to ask |
|---|---|
| Origin inland | Is pickup at my supplier included, and how many free loading hours? |
| Origin port | Terminal handling, documentation, export filings, seal |
| Ocean | Base rate plus which surcharges, and for how long is it valid? |
| Destination | Terminal handling, release, deconsolidation, delivery, free days |
A quote missing any of these is not cheaper, it is shorter. The missing segment is still paid for, only later and on someone else's invoice, so every blank in the table above is a cost to add back before ranking.
Ask for three facts: the rate validity date, whether the rate carries a general rate increase (GRI) during the validity, and whether space is allocated or "subject to availability". A rate that expires before your cargo is ready is a quotation exercise, not a price.
For shipments on an NVOCC's published tariff, the Federal Maritime Commission sets the notice rules in 46 CFR 520.8: a rate increase cannot take effect earlier than 30 calendar days after publication, and a decrease takes effect on publication. Under 46 CFR 520.7(c), the rate that applies to a shipment is the rate in effect on the date the carrier or its agent receives the cargo. The receipt date, not the quote date, fixes the price.
Surcharge treatment is where quotes diverge. 46 CFR 520.7(a)(3)(iv) and (h) allow an NVOCC to pass through the ocean carrier's published surcharges, assessorial charges, general rate increases and terminal service charges only if it lists the named charges or categories in its tariff and does not mark them up above cost. Any fee for the NVOCC's own service has to be separate and specify the service it covers.
The test for each line in a quote: is it a named carrier or terminal charge passed through at cost, or a service fee of the forwarder? Put the two in separate columns. A forwarder that cannot separate them is quoting a bundle that cannot be audited.
Free days at destination before demurrage and detention start, and whether they are calendar or working days. On lanes where clearance is slow, three extra free days are worth more than a lower ocean rate. The mechanics, including the invoice rules in 46 CFR Part 541, are in demurrage and detention.
FCL quotes are per container, LCL on weight or measure. Convert an LCL quote to a total for your actual shipment before comparing, using your real chargeable figure rather than the gross weight. If you are unsure which applies, chargeable weight covers it.
Use the same basis for every quote. Interworld Freight prices Miami LCL on a 5 CBM and 1,500 kg shipment: at 1,500 kg the cargo is 1.5 revenue tonnes against 5 CBM of volume, so it bills on volume. A quote built on another volume or weight is a different product.
Transit time and the number of transshipments, which on air freight comparisons changes the calculation entirely. Whether the forwarder controls the origin or is buying through another agent. Whether there is an owned destination operation or a partner. Whether they run their own consolidations on your lane, which decides your sailing frequency and who fixes it when a box is rolled.
For Caribbean and Latin American cargo out of Florida, the frequency question decides more than the rate. We run our own Miami consolidations and ocean services, so cut-offs and rollovers are ours to manage.
| Mode | Unit of the quote | Convert to |
|---|---|---|
| FCL | Per container | Total per container plus origin, destination and customs lines |
| LCL | Per weight or measure, whichever is greater | Total for the real chargeable figure of your shipment |
| Air | Per chargeable kilogram | Total for the chargeable weight, plus transit time in days |
The conversion is the whole comparison. Two quotes in different units are two different products until both are expressed as one total for your shipment.
Rebuild each quote as a single landed number for your shipment, add an allowance for the omissions you identified, then rank by that total. Keep transit time and free days as a second column. The cheapest total with acceptable transit wins, and it is not always the quote with the lowest headline rate.
| Column | Quote A | Quote B | Quote C |
|---|---|---|---|
| Ocean base rate | |||
| Carrier surcharges at cost | |||
| Forwarder service fees | |||
| Origin and destination charges | |||
| Customs and delivery allowance | |||
| Landed total for my volume | |||
| Transit days and free days |
Interworld Freight's July 2026 rate refresh quotes a 5 CBM, 1,500 kg Miami consolidation to Barbados at USD 795 with a 6-day transit, and to Anguilla at USD 1,015 with a 4-day transit. The two figures share a basis, so the USD 220 gap and the two extra transit days compare directly. A third quote that states only "per CBM" on one of those lanes cannot be placed beside them until it is converted to the 5 CBM total.
The same basis works across origins. For a 5 CBM, 1,500 kg consolidation to Barbados, Interworld Freight's July 2026 data gives:
| Origin | Total (USD) | Transit (days) |
|---|---|---|
| Miami | 795 | 6 |
| Valencia | 2,280 | 24 |
| Shanghai | 2,320 | 24 |
| Shenzhen | 2,350 | 41 |
The four rows show why a headline rate cannot be compared across origins: a 41-day transit from Shenzhen carries inventory cost that a 6-day Miami transit does not, even before any customs line is added. Put transit days next to every total.
Ten answers in writing turn a quote into a comparable document. A forwarder that answers all ten in one reply has already normalized its own quote.
Any one of these turns the quote into a lower bound, not a price. Ask for the missing line before ranking it.
Because they cover different scopes, use different validity periods, and treat surcharges differently. Once normalized to the same segments and the same shipment size, the spread narrows sharply.
No. Duty and taxes are assessed by the destination authority and are separate from freight.
A rate bundling the base freight and the carrier surcharges. It excludes inland transport and destination release charges unless the quote states otherwise.
The quote states its own expiry date, and that date is the answer. Check the expiry against your cargo-ready date and read the GRI wording.
Under an NVOCC tariff, the rate in effect on the date the cargo is received applies (46 CFR 520.7(c)), and an increase needs 30 calendar days of published notice (46 CFR 520.8). Get the quote, the expiry and the receipt date in writing.
An NVOCC passing through carrier surcharges must list them by name in its tariff and charge them at cost (46 CFR 520.7). Its own service fees are separate and named for the service.
Three quotes on the same shipment size and the same Incoterm give a comparable set. More quotes add normalization work without adding information, because the segment, surcharge and free time questions are identical for each one.
Only after normalizing scope. A cheap port to port rate with slow clearance and few free days costs more than a complete door to door price.
