What actually differs between these markets?
The freight rate is the smallest part of the difference. Four of the five markets take a similar time to reach, so the arrival side separates them far more than the sailing does.
Why is the freight rate the smallest part of the difference?
Because four of the five markets take a similar time to reach, and the arrival side differs far more than the sailing does. Sea transit to the UAE, Saudi Arabia and the US West Coast is the same 25–35 days; the UK adds a week to ten days. What separates these markets in cost is duty basis, import tax and registration status — none of which the freight rate touches.
UAE: what is structurally different?
Low duty is the headline, and it is real: a flat 5% is simple to predict, which makes the UAE the easiest of the five to land-cost before booking. The complication is geography rather than tariff — mainland and free-zone movements are quoted separately and are not the same transaction.
The trap to settle before booking. Free-zone versus mainland. Goods entering a free zone have not entered the UAE for duty purposes until they leave it, so which one the cargo goes to changes when duty is triggered and who can receive the goods. This is settled before booking, not on arrival.
Saudi Arabia: what is structurally different?
The same transit window as the UAE but the widest duty spread of the five: a code inside the common 5–20% range moves the landed cost by a factor of four on the duty line alone, and 15% VAT then compounds it because VAT is charged on value plus duty.
The trap to settle before booking. Conformity assessment is a cost line, not a formality. Saber / SASO conformity work sits before shipment and is charged separately from freight and duty, and anti-dumping duty applies to listed goods on top of the tariff code. Both are quoted per shipment.
US West Coast: what is structurally different?
The fastest of the five by sea, and the one with no import VAT to model — but the duty position is the most layered. Section 301 tariffs sit on top of the HTS rate for many China-origin codes, so two shipments of the same goods can differ by more than the freight if the codes differ.
The trap to settle before booking. The $800 de minimis exemption has been suspended since 29 August 2025, so every shipment now needs a customs entry. A consignment that used to clear informally does not any more. MPF and HMF also apply, and a customs bond is needed to enter goods at all.
UK: what is structurally different?
Import VAT is the highest of the five at 20%, but it is normally recoverable by a VAT-registered importer, so for a registered business it is a cash-flow item rather than a cost — and the opposite is true for a private buyer or a non-registered importer. Transit is a week to ten days slower than the Gulf.
The trap to settle before booking. The recoverability is what decides whether the 20% is a cost or a timing difference, so the VAT registration status matters more to the landed cost here than the duty rate does. Northern Ireland follows different customs rules and is quoted separately.
US East Coast: what is structurally different?
Ten to fifteen days slower than the West Coast on the same goods and the same tariff position, because the vessel either transits the Panama Canal or crosses the Pacific and moves inland. Nothing about the duty changes; only the time and the routing do.
The trap to settle before booking. Choosing the coast is the first cost decision on a US shipment and the ocean rate is only the second. A domestic leg to a West Coast port is usually cheaper than the extra two weeks of transit and the working capital tied up in it — worth pricing both before committing to the nearer coast.
