Import (Customs) Duty in Malaysia: Tariffs, HS Codes and ATIGA Preference

Two identical shipments can land in Port Klang and pay wildly different duty — not because of what they contain, but because of the eight-digit code someone typed on the declaration. That code is the whole game.

Import (customs) duty in Malaysia is charged under the Customs Act 1967 (Act 235) and administered at the border by the Royal Malaysian Customs Department (RMCD). Get the classification right and claim the origin you’re entitled to, and the bill can fall to zero. Get it wrong, and you either overpay or invite a back-duty assessment. Here’s how the machinery actually works.

What is import duty charged on?

Import duty is levied on the CIF value of the goods — Cost, plus Insurance, plus Freight to the Malaysian port of entry. It is not charged on the invoice price alone; the freight and insurance you paid to get the goods here are baked into the taxable value.

From that CIF base, duty is applied in one of two forms:

• Ad valorem — a percentage of the CIF value. This is the common case. A 5% ad valorem rate on RM100,000 of goods is RM5,000 of duty.
• Specific — a fixed amount per physical unit, regardless of value. These attach to commodities where value is a poor proxy for quantity — alcohol charged per litre, tobacco per stick or kilogram.

Most goods sit somewhere between 0% and 30% ad valorem, with much steeper rates reserved for protected, luxury, or “sin” categories. The exact number is never a matter of opinion — it is dictated by classification.

Why does the HS code decide everything?

Every physical product traded across the Malaysian border is assigned a tariff code. Malaysia uses the World Customs Organization’s Harmonized System (HS) as its backbone, extended into the ASEAN Harmonised Tariff Nomenclature (AHTN) for trade within ASEAN. The code you declare on the import form is what RMCD’s tariff schedule reads to return a duty rate.

This is why classification is the single highest-leverage decision in importing:

• The same physical item can fall under different headings depending on material, function, or degree of processing — and each heading can carry a different rate.
• An under-stated rate discovered later becomes a back-duty bill, often with penalties.
• An over-stated rate is money you simply hand over and rarely get back.

Because the stakes are real, RMCD operates a formal customs ruling process: through its Technical Services Division an importer can apply in advance — using RMCD’s customs-ruling application and the eKKB goods-classification system — for a decision on the correct tariff classification before goods ever ship, removing the guesswork at the counter.

How does sales tax stack on top of duty?

Import duty is rarely the only charge. Since the Sales and Service Tax regime returned on 1 September 2018 under the Sales Tax Act 2018, imported goods also attract sales tax — generally 10%, with a reduced 5% rate on selected categories.

The trap is the base. Sales tax is not charged on the CIF value alone — it is charged on the CIF value plus the import duty (plus excise duty, where it applies). The duty inflates the base the sales tax is then calculated on. It is, in effect, a tax on a tax.

Layer	What it’s charged on	Typical rate
Import (customs) duty	CIF value	Specific, or 0–30% ad valorem (higher on some goods)
Sales tax at import	CIF value + import duty	10% standard, 5% reduced

A worked example makes the compounding obvious. Take RM100,000 of goods carrying a 5% duty and a 5% sales tax rate:

Step	Calculation	Amount
CIF value	—	RM100,000
Import duty	5% × RM100,000	RM5,000
Sales tax base	RM100,000 + RM5,000	RM105,000
Sales tax	5% × RM105,000	RM5,250
Total landed tax	duty + sales tax	RM10,250

The RM250 gap between the RM5,000 duty and the RM5,250 sales tax is purely the tax-on-tax effect. Cutting the duty to zero under an FTA doesn’t just save the duty — it also shrinks the sales tax base.

How do ATIGA and FTAs cut the duty?

Malaysia is party to a large network of free trade agreements — MITI counts 15 concluded FTAs, including the ASEAN Trade in Goods Agreement (ATIGA) and both bilateral and ASEAN-plus agreements with partners such as China, Japan, Korea, India and Australia-New Zealand, plus RCEP and CPTPP. Each offers preferential (reduced or zero) duty for goods that genuinely originate in a partner economy.

“Preferential” is the operative word: the lower rate is a privilege you must qualify for and claim, not a default. Three things have to line up.

1. The goods must meet the Rules of Origin. Under ATIGA the general test is at least 40% Regional Value Content, or a change in tariff classification at the 4-digit level. Some products follow their own Product Specific Rules instead.
2. You must hold a valid Certificate of Origin. For ATIGA this is Form D — increasingly the paperless e-Form D transmitted through the ASEAN Single Window rather than a printed page.
3. You must lodge it with your import declaration. Present the certificate at the point of clearance; a missing, late, or defective certificate means RMCD charges the full non-preferential rate.

MITI is explicit that there is no automatic guarantee of preferential treatment — origin compliance is on the trader to prove, and authorities can conduct verification if they doubt it. On the export side, Malaysian exporters register with MITI to be authorised to issue Form D; approval is typically processed in about 3 working days and, once granted, is valid for two years.

What about cheap online parcels?

Small consignments have long enjoyed a break: goods valued at RM500 or less are generally exempt from import duty and sales tax at the border, which is what kept most courier parcels tax-free.

That gap is now partly closed. From 1 January 2024, a 10% sales tax on Low Value Goods (LVG) applies to items priced at RM500 or less that are sold online and brought into Malaysia. Instead of being collected at the border, it is charged by the seller — online sellers and marketplaces whose LVG sales into Malaysia exceed RM500,000 in 12 months must register with RMCD and collect the tax. Cigarettes, tobacco products, intoxicating liquors and smoking pipes are excluded from the LVG scheme because they are already dutiable.

The Ministry of Finance framed the change as levelling the field between physical retailers, who charge sales tax, and online imports that previously escaped it.

What’s next

Before you ship, nail the classification: identify the HS/AHTN code, and where value or risk is significant, apply to RMCD for a customs ruling so the rate is settled in advance. Then check whether the goods qualify for an FTA rate and line up the Certificate of Origin — the paperwork has to travel with the goods, not follow later.

When you model landed cost, remember the stacking order: duty on CIF first, then sales tax on CIF-plus-duty. For related detail, see the companion articles on Malaysia’s Sales and Service Tax and on the country’s free trade agreements. Duty rates and tariff codes change with each budget cycle and AHTN revision, so confirm the current rate against RMCD’s live tariff schedule before you commit a shipment.
