Saudi SASO Upgrades Fire Safety Standard for Modular Wall Panels

Saudi Standards, Metrology and Quality Organization (SASO) issued an updated fire performance standard for modular wall panels on May 28, 2026, mandating compliance from July 1, 2026. The revision elevates the required fire classification from B1 to A2-s1,d0 under EN 13501-1 and introduces mandatory smoke density and droplet testing. Exporters — particularly manufacturers and traders of prefabricated wall systems supplying the Saudi market — must now secure third-party EN 13501-1 certification and submit full test reports for customs clearance.

Event Overview

On May 28, 2026, SASO published a supplementary notice to SASO IEC 62443-4-2:2026, specifically addressing fire performance requirements for modular wall panels. The notice mandates that all such products cleared through Saudi customs must meet the A2-s1,d0 classification per EN 13501-1, replacing the previous B1-level requirement. It also adds mandatory tests for smoke density and flaming droplets. Enforcement begins on July 1, 2026. The regulation applies to all prefabricated modular wall panel products entering the Kingdom of Saudi Arabia.

Industries Affected

Direct Exporters and Trading Companies

These entities are directly responsible for customs compliance. Under the new rule, they must verify product conformity prior to shipment — failure to provide valid EN 13501-1 test reports will result in clearance delays or rejection at Saudi ports.

Manufacturers of Prefabricated Wall Systems

Manufacturers — especially those producing lightweight, insulated, or composite modular panels — face revised material selection and production process requirements. Achieving A2-s1,d0 typically necessitates non-combustible core materials (e.g., mineral wool, cement-bonded boards) and flame-retardant surface treatments, potentially altering cost structures and lead times.

Raw Material Suppliers

Suppliers of core insulation, cladding substrates, adhesives, and fire-retardant additives may see shifting demand patterns. Materials previously acceptable under B1 criteria may no longer qualify, requiring revalidation or reformulation to meet A2-s1,d0’s stricter combustion, smoke, and droplet thresholds.

Testing and Certification Service Providers

Accredited laboratories offering EN 13501-1 testing — particularly those with SASO-recognized status — are likely to experience increased inquiry volume. Demand will rise for integrated assessments covering fire behavior, smoke development (s1), and absence of flaming droplets (d0).

Key Considerations and Recommended Actions

Monitor official SASO communications for implementation clarifications

The May 28 notice is a supplement; SASO may issue further guidance on scope interpretation, transitional arrangements, or recognized testing bodies. Exporters should subscribe to SASO’s official notifications and review updates via the SASO e-Services portal.

Prioritize verification for high-volume or high-value modular wall SKUs

Not all panel configurations may require identical retesting. Companies should identify top-selling or contract-critical variants first, assess their current fire classification, and initiate EN 13501-1 testing accordingly — especially where core composition or lamination methods differ across product lines.

Distinguish between regulatory signal and operational readiness

While enforcement starts July 1, 2026, test report generation and certification can take 6–10 weeks depending on lab capacity and sample complexity. Planning must begin immediately — not upon receipt of a purchase order — to avoid supply chain disruption.

Align documentation across supply chain tiers

Certification is tied to specific product models and material batches. Exporters must ensure test reports explicitly reference the exact construction, thickness, layer sequence, and substrate brands used in commercial shipments — generic or outdated reports will not satisfy SASO’s requirements.

Editorial Perspective / Industry Observation

Observably, this update reflects SASO’s broader alignment with EU fire safety frameworks, particularly for building products entering high-density or public-use facilities. Analysis shows it is less a sudden shift than a formalized escalation of existing de facto expectations — many large-scale Saudi infrastructure projects already referenced A2-level performance in tender specifications. From an industry perspective, the July 2026 deadline signals a hard compliance threshold rather than a soft guideline; it is now a binding customs requirement, not merely a project-level specification. Continuous monitoring remains essential, as SASO may introduce additional conformity assessment modules (e.g., factory production control audits) in subsequent phases.

This regulatory update marks a structural tightening in market access conditions for modular construction components in Saudi Arabia. It does not represent a temporary adjustment but a permanent elevation of baseline fire safety expectations. For affected exporters and manufacturers, the most pragmatic understanding is that A2-s1,d0 compliance is now a non-negotiable entry condition — not a competitive differentiator.
