RMCD Customs Enforcement 2026: The Complete Guide for Foreign Companies — SST Full Enforcement, Import & Export Duties, Manufacturer Exemptions and the AEO Fast-Track

1. The 2026 Enforcement Shift: What Changed and Why It Matters

Malaysia's SST expansion was announced under Budget 2025 and took legal effect on 1 July 2025. The Ministry of Finance press release confirmed that Sales Tax at rates of 5% or 10% would apply to discretionary and non-essential goods, and that Service Tax would be expanded to include new services such as leasing or rental, construction, financial services, private healthcare, and education. To ease the transition, the government agreed that no prosecution or penalties would be imposed until 31 December 2025 for companies that took steps to comply.

That grace period is now closed. From 1 January 2026, RMCD shifted into active enforcement mode. Companies that crossed the applicable registration threshold but did not register now face backdated SST assessments from the date they should have registered, plus penalties. RMCD has signalled that it is cross-referencing LHDN income tax data, bank transaction records, and SSM company data to identify likely non-registrants — meaning the department is proactively hunting down non-compliant businesses, not waiting for them to come forward.

For a foreign company that incorporated a Malaysian Sdn Bhd in 2024 or 2025 and has been growing revenues, 2026 is the year that SST compliance must be embedded in your operations. The key enforcement risks RMCD has identified include: non-registration by companies that crossed the RM 500,000 threshold; incorrect rate application (applying 8% where 6% applies, or vice versa); non-compliance by foreign digital service providers; and failure by companies in the new July 2025 sectors — financial services, rental/leasing, healthcare, and education — to register following the expansion.

2. The SST Framework Explained: Sales Tax, Service Tax and What Changed on 1 July 2025

Malaysia operates a single-stage Sales & Service Tax (SST), not a VAT/GST. This means there is no input tax credit — SST paid at one stage of the supply chain cannot be recovered downstream. For foreign companies used to the EU VAT or Singapore GST model, this is a fundamental structural difference that affects pricing and contract design.

Sales Tax: Goods at the Border and Factory Gate

Sales Tax applies to taxable goods manufactured in Malaysia or imported. It is collected at the point of customs clearance for imports, or at the point of sale by the registered manufacturer for locally produced goods. The multi-tier rate structure in 2026 is:

Approximately 5,000 tariff lines moved from zero-rated to taxable (5% or 10%) as of 1 July 2025. The RMCD's Sales Tax (Rate of Tax) Order 2025 sets out the full HS-code-level classification. Your customs agent, acting on your K1 import declaration, will apply the rate — but the legal responsibility for correct classification rests with the importer.

Service Tax: The Expanded Service Sectors

Service Tax applies to prescribed taxable services provided by a registered person. The 1 July 2025 expansion added several new service categories that are highly relevant to foreign companies operating in Malaysia:

A notable 2026 update: the service tax rate on rental and leasing of industrial premises was reduced from 8% to 6% effective 1 January 2026. The Malaysian Government announced this on 5 January 2026, and RMCD subsequently released Service Tax Policy 2/2025 (Amendment No. 3) on 23 January 2026 to guide impacted registered persons. Additionally, the MSME exemption threshold for rental service tax was raised from RM 1 million to RM 1.5 million in annual turnover, reducing the compliance burden on smaller businesses renting industrial space.

3. Import Duties: The Layered Structure Foreign Importers Must Understand

When your company imports goods into Malaysia, RMCD applies up to three separate charges at the border — and they stack. Understanding each layer is essential for correctly computing your landed cost and identifying where exemptions can reduce the tax burden.

Layer 1: Import (Customs) Duty

Import duty is a tariff imposed on goods entering Malaysia from overseas, calculated on the CIF (Cost, Insurance, and Freight) value of the goods. Rates range from 0% to 60% on an ad valorem basis, determined by the HS code classification of the goods. Import duties protect domestic industries, regulate the inflow of goods, and generate government revenue. To calculate import duty, you multiply the CIF value by the applicable import duty rate for the goods' HS code.

Layer 2: Import Sales Tax

Import Sales Tax is the second charge, applied on top of import duty. It is calculated on the CIF value plus import duty value plus any applicable excise duty. The import sales tax rate is 5% or 10% (or a specific rate) depending on the product's HS code. Critically, 0% import duty does NOT mean 0% sales tax — many goods carry 0% import duty but still attract 5% or 10% sales tax at the border. Always check both rates separately when working out your landed cost.

Layer 3: Excise Duty (Selected Goods Only)

Excise duties are imposed on a selected range of goods manufactured in Malaysia or imported, including beer, stout, alcoholic beverages, cigarettes, electronic cigarettes, motor vehicles, motorcycles, playing cards, and mah-jong tiles. Rates vary from composite rates for beverages to specific per-unit rates. For example, cigarettes carry a rate of RM 0.40 per stick (with Budget 2026 proposing a RM 0.02 increase); motorcars attract rates up to 105% depending on engine capacity.

4. Manufacturer Exemptions: Legally Eliminating Import Sales Tax

For foreign companies in manufacturing — which is one of the most common entry routes into Malaysia under a Manufacturing Licence (ML) or Exempted ML — the SST exemption framework under the Sales Tax Act 2018 can legally eliminate the 10% import sales tax on raw materials, components, and packaging used in production. This is a critical cost advantage that many newly incorporated foreign manufacturers miss.

Schedule C: The Manufacturer's Exemption

Schedule C (under the Sales Tax (Persons Exempted from Payment of Tax) Order 2018) is the most commonly used exemption category. Registered manufacturers can import raw materials, components, and packaging used directly in production at 0% sales tax. The supply of critical raw materials and agricultural inputs used by registered manufacturers — including animal feed, fertilisers, and pesticides — is also zero-rated under the expanded framework.

The process works as follows: the manufacturer obtains an exemption certificate (SST-ADM or similar) from RMCD before the shipment arrives. The certificate is presented at customs clearance, and the goods are cleared without payment of sales tax. If you attempt to claim a refund after paying tax, the process is significantly longer and more uncertain. Getting the exemption certificate approved before shipment is far faster than chasing a refund afterward.

Approved Major Exporter Scheme (AMES)

Companies that manufacture finished goods that are exempt from sales tax and primarily export their production can apply for the Approved Major Exporter Scheme (AMES). Under this scheme, raw materials and packaging imported under AMES facilities benefit from deferred or waived sales tax obligations, further reducing the working capital tied up in import taxes for export-oriented manufacturers.

Free Trade Zones (FTZs) and Licensed Manufacturing Warehouses (LMW)

Malaysia's Free Trade Zones offer businesses exemptions from customs duties and excise duties on goods imported, processed, or manufactured within them, provided those goods are re-exported rather than sold domestically. For export-oriented manufacturers, an LMW (Licensed Manufacturing Warehouse) licence — issued under Section 65 of the Customs Act 1967 — delivers similar benefits: duty-free importation of production inputs and streamlined customs monitoring. LMW applications are submitted to the RMCD Zone Operations Director or State Customs Director for the relevant state, accompanied by a detailed layout plan, operational description, and supporting documentation. RMCD will conduct a premises inspection before issuing the licence.

5. The Authorised Economic Operator (AEO) Programme: The Regional Supply-Chain Advantage

The Authorised Economic Operator (AEO) programme is one of RMCD's most significant trade facilitation tools — and one that is frequently overlooked by foreign companies in the early stages of Malaysia market entry. In 2026, with the ASEAN AEO Mutual Recognition Arrangement (AAMRA) now operational across five ASEAN member states, AEO accreditation has moved from a "nice to have" to a strategic supply-chain advantage.

What AEO Status Provides

Companies that have met RMCD's compliance and security standards are accredited as AEOs and enjoy customs benefits including automatic approval of self-declarations of import, export, and transit, and deferred payment of duty and tax. The programme is open to all stakeholders such as manufacturers, importers, exporters, customs agents, and warehouse operators involved in the international supply chain. No accreditation fee is charged by RMCD.

ASEAN-Wide Mutual Recognition

The ASEAN AEO Mutual Recognition Arrangement (AAMRA) came into effect on 1 August 2024, initially covering Brunei, Malaysia, and Singapore. Thailand joined on 19 August 2024, Indonesia on 1 October 2024, and the Philippines on 28 February 2025. Certified ASEAN AEOs enjoy faster cargo clearance and priority inspection treatment across all participating member states. Additionally, Malaysia and Singapore signed a bilateral AEO MRA on 18 January 2024, operational from 30 July 2024. This means your cargo receives facilitated treatment not just when it leaves Malaysia, but when it arrives at the destination country.

For a Chinese, Taiwanese, or Singaporean manufacturer that has established a Malaysian production or distribution hub and is shipping regularly to ASEAN markets, AEO accreditation provides a compounding competitive advantage: faster throughput at every border, lower inspection rates, and deferred duty payment — all of which improve working capital and order-fulfilment cycles.

The AEO Application Process

Malaysia's AEO programme operates as a single accreditation status. Once RMCD validates that a company meets all required compliance and security standards, the company is accredited as an Authorised Economic Operator, subject to periodic re-validation. The compliance assessment covers 66 questions across 14 key areas, from customs compliance history and financial viability to physical premises security and personnel vetting. The three-to-six-month application timeline means that companies beginning their preparation today could achieve accreditation before the end of 2026.

6. Step-by-Step: SST Registration and Ongoing Compliance for a Foreign-Owned Sdn Bhd

This section walks through exactly what a newly incorporated foreign-owned Sdn Bhd must do to achieve and maintain SST compliance in 2026.

Step 1: Determine Your SST Obligation

Identify every product you manufacture or import (Sales Tax) and every service you provide (Service Tax). Match each to the updated HS code or service tax group. Quantify your rolling 12-month taxable revenue for each category. If you import goods, remember to check both import duty rate AND import sales tax rate separately for each HS code.

Step 2: Monitor Your Threshold

Track your rolling 12-month taxable turnover against the relevant threshold: RM 500,000 for most service categories and for taxable goods manufacturing; RM 1,000,000 for leasing and financial services; RM 1,500,000 for construction and private healthcare. Once you hit the threshold, the 30-day registration clock starts.

Step 3: Register on MySST

Registration is done through the MySST portal at mysst.customs.gov.my. Note that Sales Tax and Service Tax registrations are separate — each has its own registration form and submission process. You will need your company registration number, a description of your business activities, your taxable service categories or goods categories, and your expected annual taxable turnover. Approval is typically issued promptly upon submission.

Step 4: Invoice Correctly

Once registered, every taxable invoice must display the correct SST rate. Applying 8% where 6% applies (or vice versa) exposes you to RMCD penalties. Under Malaysia's Phase 3 e-invoicing rules (in effect from 1 January 2026 for companies with annual turnover above RM 25 million), SST amounts must also be correctly reflected in your e-invoice submissions to LHDN. Update your ERP, POS, and accounting systems to handle multiple tax codes: 5%, 6%, 8%, and 10%.

Step 5: File SST-02 Returns Bi-Monthly

SST returns (Form SST-02) are filed bi-monthly through the MySST portal. The taxable period runs every two months, and the return and payment are due within one month after the end of each taxable period. Late filing or payment triggers penalties. Engage a licensed tax agent or professional service provider — such as our Corporate Tax Filing service — to handle bi-monthly SST filing and ensure every return is accurate and on time.

Step 6: Maintain Exemption Certificates

If you are a registered manufacturer using Schedule C exemptions, ensure your exemption certificates are renewed before expiry and are presented to your customs agent before each import shipment. Keep audit-ready records of all exemption-eligible purchases and the corresponding production usage, as RMCD audits will verify that exempted inputs were actually used in the manufacturing process.

7. Worked Example: A Chinese Electronics Manufacturer Setting Up in Malaysia

Consider a Chinese electronics company that has incorporated a Sdn Bhd in Penang to assemble printed circuit boards (PCBs) for export to the ASEAN market, with some domestic sales in Malaysia. Here is how the RMCD compliance landscape applies:

• Import of raw materials (copper sheets, ICs, passive components): These carry 0% import duty under Malaysia's trade agreements but attract 5% or 10% import sales tax depending on HS code. Applying for a Schedule C Manufacturer's Exemption certificate pre-shipment eliminates the import sales tax on qualifying inputs, saving potentially hundreds of thousands of ringgit per year on a high-volume operation.
• LMW licence: Because the operation is primarily export-oriented, applying for a Licensed Manufacturing Warehouse (LMW) licence enables duty-free importation of all production inputs and simplified RMCD customs monitoring — a significant operational advantage over ad-hoc import declarations.
• Service Tax on management services from HQ: If the Malaysian Sdn Bhd pays management fees to its Chinese parent company, and those management services were provided by a taxable person registered in Malaysia, this could create a Service Tax obligation. Structure intra-group service agreements carefully.
• Service Tax on professional services consumed: If the Sdn Bhd engages Malaysian IT service providers, accounting firms, or legal advisers, it will receive invoices with 8% Service Tax included — this is a cost, not a recoverable credit. Budget accordingly.
• AEO application: With regular high-volume cross-border shipments to Singapore, Thailand, and Indonesia, the company is an ideal candidate for AEO accreditation. The three-to-six-month process, begun now, would deliver automatic import approvals, deferred tax payment, and priority clearance across all AAMRA-participating states — directly improving cash flow and delivery timelines.
• SST-02 filings: Once registered (mandatory given likely revenue above RM 500,000 within months of operation), bi-monthly SST-02 returns must be filed through MySST. This is where working with a professional tax compliance partner pays for itself.

The total RMCD compliance burden for this company is real but manageable — provided the right licences, exemption certificates, and registration are in place before production begins. Setting these up after the fact typically results in backdated assessments that could have been avoided. This is exactly why ONEKEY BIZ includes customs and tax compliance advisory in its full market-entry support, alongside our Corporate Tax Filing service for ongoing SST and corporate tax returns.

8. Common Mistakes Foreign Companies Make — and How to Avoid Them

• Assuming overseas-only revenue exempts you from SST: Many foreign companies assume that because they primarily serve overseas customers, they are outside the SST net. This is wrong. If your Malaysian Sdn Bhd provides taxable services from Malaysia — even to foreign customers — the Service Tax obligation can still apply depending on the nature of the services and how they are structured.
• Not separating import duty from import sales tax: Paying 0% import duty and assuming no tax is due at the border is a common and expensive error. Check the sales tax rate separately for every HS code — many goods with 0% duty still attract 5% or 10% sales tax.
• Using wrong HS codes on K1 declarations: HS code misclassification is the single most common trigger for RMCD post-clearance audits. One wrong code affects the duty rate, the sales tax rate, and the applicability of any exemption. Use a licensed customs agent and verify codes against the RMCD's official tariff schedule.
• Missing the 30-day registration window: Once your rolling 12-month taxable turnover crosses the threshold, you have 30 days to register. Missing this window results in backdated assessments from the date you should have registered. Monitor your revenue monthly, not annually.
• Not applying for manufacturer exemptions before shipment: Claiming a refund of import sales tax paid on inputs that should have been exempt is significantly slower and less certain than obtaining the exemption certificate before the shipment arrives. Apply for Schedule C exemptions as part of your production setup process.
• Ignoring the rental service tax change: Companies leasing industrial premises from 1 July 2025 — even if they received their first invoice before the January 2026 rate change — need to verify they are being charged the correct 6% rate (not 8%) on post-January 2026 rental invoices, and update their SST-02 reporting accordingly.
• Delaying AEO application: Many companies do not think about AEO until they are already established and experiencing customs delays. Given the three-to-six-month application timeline and the ASEAN-wide benefits now available, starting the AEO process during or shortly after your Malaysian incorporation is far more strategic.

9. What to Do Next: Your RMCD Compliance Action Plan for 2026

The convergence of full SST enforcement, expanded service tax sectors, HS code-driven sales tax on thousands of new import lines, and the maturing ASEAN AEO framework means that RMCD compliance is now a strategic business function — not just a back-office administrative task. For foreign companies entering Malaysia or scaling their existing Malaysian operations, here is a practical action plan:

1. Map your full SST exposure immediately. List every good you import or manufacture and every service you provide. Match each to the updated HS code or service tax group. Calculate the implied SST liability under the 2025/2026 rules.
2. Register for SST if you have crossed or are approaching the threshold. Do not wait. Register via mysst.customs.gov.my for the relevant tax categories. Registration is separate for Sales Tax and Service Tax.
3. Apply for manufacturer exemptions and LMW licence if you are a manufacturer. These should be in place before your first production import shipment. Apply for Schedule C exemption certificates through RMCD's technical services.
4. Begin AEO pre-assessment. Review the compliance checklist at aeo.customs.gov.my. Identify gaps in your customs compliance history, financial controls, and physical security. Build a remediation roadmap. A three-to-six-month application timeline is realistic for a well-prepared company.
5. Update your contracts and ERP systems. Insert SST clauses in all supply and service contracts. Update your invoicing system to handle multiple SST rates (5%, 6%, 8%, 10%) and ensure compatibility with Malaysia's e-invoicing requirements.
6. Engage professional tax compliance support. Bi-monthly SST-02 filing, corporate tax returns, exemption certificate management, and customs audit defence all require specialist knowledge. Our Corporate Tax Filing service covers SST and corporate income tax for foreign-owned Malaysian companies — handled by professionals who understand the RMCD framework from the inside.
