The cost of importing or exporting through Port Klang is never a single figure — it is a stack of charges built from the goods, the freight, the duty and tax, and the inland movement. This guide explains what each charge is, what makes it go up or down, and where to find the worked numbers, so you can read a quote rather than just react to it.
What you actually pay (the stack)
- Goods + international freight + insurance — the landed value before tax
- Import duty — a percentage set by the HS code
- Sales tax (SST) — standard 10% on the CIF value of most goods
- Terminal, documentation & haulage — releasing and delivering the box
- Demurrage & detention — only if collection or return runs late
What determines your import duty and SST?
Duty is a percentage set by the product's HS code and published by the Royal Malaysian Customs Department; sales tax under SST is a standard 10% on the CIF customs value of most goods, with some at 5% or exempt. A valid free-trade-agreement certificate of origin can cut the duty to zero. The worked maths is in how to calculate import duty and SST, with the SST detail in SST on imports.
How much does the freight cost?
Freight depends on mode (sea or air), volume (FCL or LCL), the lane and the state of the market. Rates from China differ from Vietnam, and the whole market swings with capacity and fuel. See the lane-by-lane numbers in importing from China and the market view in the 2026 freight-rate surge.
What does haulage and the "last mile" add?
Inland haulage is built from a base tariff (driven by distance from Port Klang), tolls and a fuel adjustment factor, with 20ft and 40ft containers priced differently. The breakdown and sample routes are in haulage rates and routes.
Where do hidden costs come from?
The charges that surprise people are usually avoidable: demurrage and detention when a box is collected or returned late, storage when a permit is missing, and duty overpaid because of a wrong HS code. They show up in the true cost of importing a container, and the worst one is tackled in avoiding demurrage and detention.
How do you bring the total down?
Real savings come from the whole chain, not one rate: correct classification, the right Incoterm, an FTA certificate of origin where it applies, consolidating shipments, and tight haulage to kill demurrage. The practical levers are in cutting logistics costs. A useful habit is to compare quotes on total landed cost, not on the headline freight rate, because the cheapest rate often carries the most expensive extras. For a number specific to your shipment, the fastest route is to ask us for a quote — we price clearance, freight and haulage as one landed figure, with the avoidable charges called out so there are no surprises at the port.
