Zhiwai maps SF₆ switchgear rules for Singapore and Malaysia buyers

Zhiwai says MV switchgear buyers in Singapore and Malaysia need to separate local emissions-reporting duties from overseas equipment restrictions before setting procurement specs. The guide flags reporting obligations in both countries, while noting that EU and US state limits affect supply and corporate policy more than local law.

Why it matters: - MV switchgear buyers in Singapore and Malaysia need to know whether SF₆ rules come from local law, utility approval or corporate policy. - The distinction affects procurement specs, emissions reporting, lifecycle planning and supply risk. - A wrong assumption about overseas rules can lead to unnecessary tender constraints or missed compliance duties.

What happened: - Zhiwai published a review on October 28, 2026, examining how SF₆ and other fluorinated greenhouse gas rules affect medium-voltage switchgear procurement in Singapore and Malaysia. - The review uses regulatory texts, official guidance and published statements available on October 26, 2026. - Zhiwai says EU and US state equipment restrictions do not directly govern installations in Singapore or Malaysia. - The guide says local buyers should first establish emissions-reporting obligations and project requirements, then assess how overseas developments could affect product availability and corporate specifications.

The details: - In Singapore, NEA guidance classifies SF₆ emitted during manufacture, installation, use or disposal of electrical equipment as non-reckonable under the Carbon Pricing Act. - Those emissions are excluded from carbon-tax and registration-threshold calculations, but they remain reportable by facilities covered by the reporting rules. - ACRA requires all SGX-listed companies to report Scope 1 and Scope 2 emissions from FY2025. - Switchgear leakage inside the reporting entity’s ownership or control boundary therefore needs to be treated as a direct-emissions source. - Malaysia’s National Sustainability Reporting Framework rolls out ISSB-based reporting in phases: large Main Market issuers from 2025, other Main Market issuers from 2026, and ACE Market issuers and qualifying large non-listed companies from 2027, subject to reliefs. - Those rules make equipment emissions data relevant to covered operators. - Malaysia’s planned national carbon tax is not yet active; on October 5, 2026, the minister responsible for environmental sustainability said implementation had been deferred. - Buyers should not treat the proposed tax as an existing charge on SF₆ switchgear leakage. - The EU F-gas Regulation covers SF₆ and other fluorinated greenhouse gases. - Article 13(9) restricts putting into operation MV switchgear for primary and secondary distribution using fluorinated greenhouse gases in the insulating or breaking medium from January 1, 2026, up to and including 24 kV, and from January 1, 2030, above 24 kV up to and including 52 kV, subject to derogations. - The MV provisions do not use a global warming potential threshold, so an SF₆-free label or low-GWP mixture does not automatically mean compliance. - California’s switchgear regulation under section 95352 and New York’s Part 495 apply SF₆-specific equipment acquisition restrictions. - For aboveground equipment below 38 kV, the starting dates are January 1, 2025, in California and January 1, 2027, in New York, with exemptions and transition provisions. - Other equipment categories have different dates. - Those state milestones are not the same as the EU’s putting-into-operation rules and should not be copied into a Singapore or Malaysia tender as local statutory deadlines. - The review did not identify an equivalent nationwide, voltage-based MV switchgear phase-out timetable for Singapore or Malaysia. - Zhiwai says overseas action alone does not mean either country will adopt the same rules or dates. - TNB describes planned SF₆-free RMU and gas-free hybrid GIS pilots to assess performance under Malaysian operating conditions. - That activity suggests buyers should monitor utility specifications and technology acceptance alongside formal legislation. - If fluorinated gases are excluded, the tender should say so for both insulation and current interruption. - Tender requests should ask for the media and constituents, applicable GWP basis, nameplate gas mass, leakage information, and servicing and recovery instructions. - Operating records should capture gas additions, recovery and disposal using the relevant reporting framework’s calculation method. - Nameplate gas capacity alone is not an annual emissions figure.

Between the lines: - The guide is less about a single compliance deadline and more about preventing buyers from mixing together three different rule sets: local reporting, utility acceptance and foreign market restrictions. - Zhiwai is also signaling that supply-chain choices made for Europe or the U.S. may shape what is commercially available in Southeast Asia, even when they are not legally required there. - The reporting focus matters because emissions data can affect corporate disclosures even where carbon tax treatment differs.

What's next: - Buyers are expected to map each requirement to its source before issuing tenders. - Manufacturers, utilities and corporate procurement teams will likely continue to shape SF₆-free and low-GWP specifications through product roadmaps and approval criteria. - Singapore and Malaysia buyers should watch for further changes in local reporting rules, utility pilots and any future carbon-pricing decisions.

The bottom line: - For MV switchgear in Singapore and Malaysia, local compliance comes first, but overseas restrictions can still shape supply, specifications and long-term operating risk.
