Every shipment crossing Malaysia’s border needs a declaration — and the two forms you’ll encounter most often are K1 and K2. Get them confused, or file one with incomplete supporting documents, and your cargo sits at the port accruing storage charges while everything else waits. This guide breaks down exactly what K1 and K2 forms are, how they differ, what documents each one requires, and where a licensed customs agent fits into the process.
Paramount Express Agencies has filed K1 and K2 declarations across Malaysia’s major ports since 1997. Here’s the complete breakdown — plus free downloadable templates for both forms.

What Is the K1 Form?
The K1 form (Borang Kastam K1) is Malaysia’s official import declaration. It’s required whenever goods enter Malaysia’s Principal Customs Area (PCA) from overseas, and it serves as the basis for the Royal Malaysian Customs Department (RMCD/JKDM) to assess and collect import duty, Sales and Service Tax (SST), and any applicable excise duty.
Importantly, “import” under RMCD’s framework isn’t limited to goods arriving from another country. Because Free Trade Zones (FTZ) and Malaysia’s duty-free islands — Labuan, Langkawi, Tioman, and Pangkor — are legally treated as outside the Principal Customs Area, goods moving from those zones into the PCA are also classified as an import and require a K1, even though the goods never physically left Malaysian territory.
Once submitted, a customs officer reviews the K1 declaration — verifying the HS code classification, checking the declared value against reference data, confirming that any required permits are in order, and calculating the duty and tax payable. Payment must be settled before RMCD issues a release order allowing the goods to leave the port or airport.
What Is the K2 Form?
The K2 form (Borang Kastam K2) is the export declaration — effectively the mirror image of the K1. Under the Customs Act 1967, all goods leaving Malaysia’s Principal Customs Area must be declared to JKDM, even when no export duty applies to the specific product.
Applying the same PCA logic in reverse, a K2 is required whenever goods move out of the Principal Customs Area — which covers more scenarios than most businesses expect:
- Direct exports overseas — goods shipped by sea, air, or land straight to another country
- Shipments from Licensed Manufacturing Warehouses (LMW) — export-oriented manufacturers moving goods out under LMW status
- Transfers from the PCA to Free Trade Zones or duty-free islands — since FTZs and islands like Labuan and Langkawi sit outside the PCA, moving goods there from Peninsular Malaysia’s mainland counts as an export
The direction matters: PCA → FTZ/duty-free island is a K2 (export); FTZ/duty-free island → PCA is a K1 (import). Getting this backwards is a common and costly mistake.
Free K1 & K2 Form Downloads
For your reference, here are downloadable templates of both forms:
These templates are provided for reference only. Note that under RMCD’s uCustoms system, the K1 and K2 are largely system-generated outputs — your licensed customs agent enters shipment details (invoice, packing list, Bill of Lading, permits) directly into RMCD’s declaration system, which then generates the form. Always verify you’re working from the current process with a licensed customs agent rather than manually completing a static template for actual submission.
K1 and K2: Side-by-Side Comparison
| Factor | K1 Form | K2 Form |
|---|---|---|
| Purpose | Import declaration | Export declaration |
| Triggered by | Goods entering the Principal Customs Area — including from overseas, or from an FTZ/duty-free island | Goods leaving the Principal Customs Area — including overseas exports, or transfers to an FTZ/duty-free island |
| Tax calculated | Import duty, SST, excise duty | Export duty (where applicable — most goods are duty-free on export) |
| Core documents needed | Invoice, packing list, Bill of Lading, Arrival Notice | Invoice, packing list, Booking Confirmation |
| Filed via | uCustoms system (RMCD) | uCustoms system (RMCD) |
Documents Required for K1 (Import)
A standard K1 declaration is typically supported by these core documents, which your licensed agent enters into the uCustoms system:
- Commercial invoice — states the transaction value used for customs valuation
- Packing list — details the contents of each package or container
- Bill of Lading (or Air Waybill for air freight) — the transport document confirming carriage
- Arrival Notice — confirms the shipment has physically arrived and is ready for clearance
- SSM company registration number — required as part of the declaration itself
If your goods qualify for preferential duty under a free trade agreement, a valid Certificate of Origin should also accompany the declaration — without it, the standard Most Favoured Nation duty rate applies instead. Controlled goods also require the relevant Approved Permit (from MITI, SIRIM, MAQIS, or another regulator) before the K1 can clear.
Documents Required for K2 (Export)
A K2 declaration typically requires:
- Commercial invoice
- Packing list
- Booking Confirmation — confirms the cargo space reserved with the carrier
Fewer documents than a K1, but accuracy still matters just as much — a mismatch between the declared value, HS code, and supporting paperwork is one of the most common reasons a K2 gets held for further review, and directly jeopardises any future duty drawback claim tied to that export (more on this below).
Other Customs Forms: K3, K8, K9
K1 and K2 cover the majority of standard shipments, but Malaysia’s customs system includes several other forms for specific scenarios:
- K3 — used for coastal/transit declarations for goods moving between Malaysian ports
- K8 — used for transit and transhipment movements, where goods pass through Malaysia without formally entering the Principal Customs Area
- K9 — used for warehouse withdrawal declarations
- ZB1, ZB2, ZB3 — a separate series specifically for movements into, out of, and within Free Zones, used alongside the K-series depending on the nature of the movement
Most businesses will only ever deal with K1 and K2, but if your supply chain involves transhipment, warehouse withdrawals, or Free Zone movements specifically, confirm with your customs agent which additional form applies.
Who Can File K1 and K2 Declarations?
Under Section 90 of the Customs Act 1967, a declaration can be made by the goods owner or an Authorised Customs Broker. In practice, RMCD grants direct access to the customs declaration system only to licensed customs agents — meaning the K1 or K2 form itself is a system-generated output of the uCustoms platform, not a document manually filled in and submitted. Your agent enters the shipment details, and the system generates the official declaration once submitted.
Common Mistakes That Delay Clearance
Most customs clearance delays in Malaysia aren’t caused by complex regulations — they’re caused by incomplete or inconsistent documents. The most frequent issues:
- Mismatched details across documents — the declaration, commercial invoice, and shipment label must match exactly under Malaysia’s digital-first system
- Incorrect HS code classification — even small differences in product classification can significantly change duty and tax exposure, since Malaysia follows the ASEAN Harmonised Tariff Nomenclature (AHTN)
- Missing required permits — controlled goods need MITI, SIRIM, or MAQIS approval in hand before the K1 or K2 can clear
- Confusing import vs export direction — assuming a Free Trade Zone or duty-free island transfer is always one or the other, when the correct form depends entirely on which direction the goods are moving relative to the Principal Customs Area
K2 and Duty Drawback: A Benefit Most Exporters Miss
If your business imports raw materials, pays import duty on them, and then manufactures those materials into finished goods for export, you may be entitled to claim a duty drawback refund from RMCD. A properly validated K2 form is the key supporting document for that claim — if the K2 records are incomplete or the HS codes on it are incorrect, RMCD can reject the drawback application outright. This is a benefit many exporters qualify for but never claim, simply because their export documentation wasn’t set up with drawback eligibility in mind from the start.
Why Work With a Licensed Customs Agent
Since K1 and K2 declarations can only be generated by a party with direct access to RMCD’s uCustoms system, most importers and exporters work through a licensed forwarding agent rather than attempting to self-file. Beyond system access itself, an experienced agent catches HS code and documentation issues before submission — the difference between clearing on the green lane and getting pulled aside for review.
Paramount Express Agencies has filed K1 and K2 declarations across Port Klang, Penang Port, and Pasir Gudang since 1997, coordinating classification, documentation, and clearance as part of a full freight forwarding service.
Frequently Asked Questions
What’s the difference between K1 and K2 forms?
K1 is the import declaration, used whenever goods enter Malaysia’s Principal Customs Area — from overseas, or from a Free Trade Zone or duty-free island. K2 is the export declaration, used whenever goods leave the Principal Customs Area, whether overseas or to an FTZ/duty-free island.
Is a transfer to a Free Trade Zone a K1 or a K2?
It depends on direction. Moving goods from the Principal Customs Area into an FTZ or duty-free island (like Langkawi or Labuan) is a K2, since it’s treated as an export. Moving goods from that FTZ or island back into the Principal Customs Area is a K1, since it’s treated as an import.
What documents do I need for a K1 declaration?
Typically a commercial invoice, packing list, Bill of Lading (or Air Waybill), and Arrival Notice, plus your SSM company registration number. A Certificate of Origin is also needed if claiming preferential duty under a free trade agreement.
Can I claim a refund on import duty if I export the finished product?
Potentially, yes, through RMCD’s duty drawback scheme — if you paid import duty on raw materials later used to manufacture goods for export. A correctly filed K2 with accurate HS codes is required to support the claim.
Can I file K1 and K2 forms myself, or do I need an agent?
Under Section 90 of the Customs Act 1967, the goods owner or an Authorised Customs Broker can make the declaration. In practice, since only licensed agents have direct access to RMCD’s uCustoms system, most importers and exporters work through a licensed forwarding agent.
Where can I download a K1 or K2 form template?
Reference templates are available above via the download buttons on this page. Note that the actual K1/K2 submitted to RMCD is generated by the uCustoms system based on data your licensed agent enters — for real submissions, always work through a licensed customs agent rather than manually completing a static template.
