Saudi Arabia’s Standards, Metrology and Quality Organization (SASO) issued SASO 2663:2026 on May 15, 2026, mandating new water efficiency requirements for all imported washing machines—including commercial and industrial units—and introducing additional testing for integrated water treatment modules. Industrial water treatment system exporters, corrosion-resistant valve component manufacturers (e.g., bearings and seals), and related supply chain stakeholders must now assess revised certification pathways and compliance timelines.

Event Overview

On May 15, 2026, SASO published SASO 2663:2026. The standard requires all imported washing machines—regardless of application scope (residential, commercial, or industrial)—to achieve a minimum 5-star water efficiency rating as complete appliances. Additionally, any built-in water treatment module (e.g., water softeners, reverse osmosis membrane assemblies) must undergo separate evaluation for flow decay rate and salt rejection rate. No further implementation dates, transitional provisions, or test protocol details have been publicly released beyond the standard’s publication.

Industries Affected

Industrial Water Treatment Equipment Exporters

These exporters are directly affected because their modules—integrated into washing machines for scale prevention or feedwater conditioning—are now subject to standalone performance verification. Impact manifests in extended pre-market testing cycles, potential redesign of module housings or control logic to meet flow stability thresholds, and increased documentation burden for SASO conformity assessment.

Manufacturers of Corrosion-Resistant Valve Components (Bearings & Seals)

Suppliers of critical fluid-path components—including precision valve cores, dynamic seals, and bearing assemblies used in RO or softening modules—face downstream impact. Since flow decay rate testing reflects long-term hydraulic integrity under repeated cycling, component-level durability and material compatibility with Saudi water chemistry become de facto compliance factors—even if those components are not certified individually.

OEMs and System Integrators of Commercial/Industrial Washing Equipment

Companies assembling full washing systems for laundromats, hotels, or textile facilities must now validate both whole-unit water efficiency and subsystem-level water treatment performance. This introduces dual-layer certification complexity: one for appliance-level labeling (5-star), another for embedded module functionality—potentially requiring coordination across multiple third-party labs and technical files.

What Relevant Enterprises or Practitioners Should Focus On and How to Respond

Monitor official SASO communications for implementation timelines and test method references

SASO 2663:2026 has been published, but no enforcement date, grace period, or referenced test standards (e.g., ISO, IEC, or SASO-specific methods for flow decay or salt rejection) have been confirmed. Stakeholders should track SASO’s official portal and authorized conformity assessment bodies for updates before initiating lab work.

Prioritize validation of high-volume or high-risk module configurations

Exporters should identify which water treatment module types (e.g., compact RO cartridges vs. multi-stage softeners) are most commonly integrated into top-selling washing machine models destined for Saudi importers. Focused testing on these configurations helps allocate resources efficiently ahead of broader rollout.

Distinguish between regulatory signal and operational readiness

The issuance of SASO 2663:2026 signals tightening water resource governance—not yet an active barrier. Until SASO announces mandatory application dates or customs enforcement instructions, current shipments remain unaffected. However, procurement decisions made today (e.g., selecting seal materials or membrane suppliers) may constrain future compliance options.

Initiate cross-functional alignment between R&D, QA, and export compliance teams

Because water efficiency and module performance intersect mechanical design, material selection, and firmware-controlled rinse cycles, early internal alignment ensures test planning accounts for interdependencies—such as how pressure drop across a seal influences measured flow decay over 1,000-cycle endurance tests.

Editorial Perspective / Industry Observation

Observably, SASO 2663:2026 functions less as an immediate trade barrier and more as a forward-looking policy signal aligned with Saudi Vision 2030’s water conservation goals. Analysis shows that the inclusion of module-specific metrics—rather than relying solely on whole-appliance water consumption—reflects a shift toward regulating embedded technology performance within end-use appliances. From an industry perspective, this suggests growing regulatory attention on subsystem-level sustainability claims, especially where water or energy savings depend on auxiliary components rather than core motor or drum design alone. Current relevance lies not in immediate noncompliance risk, but in its indication of evolving expectations for system-level environmental accountability in regulated markets.

Conclusion: SASO 2663:2026 does not yet alter market access conditions, but it redefines the technical scope of compliance for washing machine exports to Saudi Arabia. It is better understood as a calibrated escalation in regulatory granularity—focusing on water treatment subsystems—rather than a broad-based efficiency mandate. Stakeholders are advised to treat it as a lead indicator for similar requirements in other Gulf Cooperation Council (GCC) markets, while prioritizing clarity on implementation timing before committing to new testing or design iterations.
