Complete Guide to SASO Coating VOC Limits 2025 for Manufacturers
Volatile Organic Compound (VOC) limits for coatings in Saudi Arabia are not new — but enforcement through the SABER product conformity system has become increasingly rigorous, and the Vision 2030 development programme is pushing project specifications beyond what SASO minimum requirements demand. For paint manufacturers selling into the Saudi market in 2025 and beyond, understanding and meeting these limits is now a prerequisite for market access, not an optional consideration. This guide covers every relevant limit, measurement method, and raw material strategy for compliance.
Key standard: Saudi Arabia adopts GSO 1914 (Gulf Standardisation Organisation) as its primary VOC limit regulation for decorative and architectural coatings. This is enforced through the SABER product conformity system, which requires third-party certification before products can be placed on the Saudi market.
VOC Limits by Product Category (GSO 1914 / SASO)
| Product Category | Subcategory | VOC Limit (g/L) | Notes |
|---|---|---|---|
| Interior wall coatings | Flat/matt | 30 | Applies to wall and ceiling paints; most interior emulsions |
| Interior wall coatings | Non-flat (eggshell, satin) | 150 | Includes semi-gloss where sheen >25 at 60° |
| Interior wall coatings | Gloss | 380 | Full gloss interior — uncommon in Saudi market |
| Exterior wall coatings | Flat/matt | 50 | Exterior façade paints |
| Exterior wall coatings | Non-flat | 150 | Exterior semi-gloss/satin |
| Exterior wall coatings | Gloss | 250 | Exterior gloss topcoat |
| Trim and door paints | Non-flat | 150 | Waterborne preferred; alkyds increasingly restricted |
| Trim and door paints | Gloss | 380 | High-gloss trim |
| Primers | Interior | 30 | Sealer and primer-sealer |
| Primers | Exterior | 50 | Surface primers for exterior masonry and render |
| Primers | Anti-corrosive (metal) | 250 | Solventborne metal primers — still permitted |
| Industrial and protective | Anti-corrosive | 250–500 | Industrial coatings are separately regulated |
SABER Certification — What It Means for VOC
SABER (Saudi Product Safety Programme) requires conformity certification for regulated products before they can enter Saudi Arabia. For coatings subject to GSO 1914:
- The manufacturer must have the product tested by a SABER-recognised certification body (CB).
- VOC testing must be done by an ISO/IEC 17025-accredited laboratory using ISO 11890-2 or ASTM D2369.
- A Product Conformity Certificate (PCC) is issued and linked to the SABER online system.
- Shipments without a valid SABER certificate will be detained at Saudi customs.
Raykem recommends that all paint manufacturers selling into Saudi Arabia maintain current SABER certificates for their full product range and review them annually, as new product batches with changed formulations may require re-testing.
Raw Material Strategies for VOC Compliance
The most effective approach to VOC reduction depends on your current system type:
- Waterborne systems already at target: Review your coalescent. Texanol (2,2,4-trimethyl-1,3-pentanediol monoisobutyrate) is the standard low-VOC coalescent for emulsion paints. Some coalescents classified as VOC-exempt in the US (e.g. acetone) are not exempt under EU or GSO definitions — check the applicable standard.
- Solventborne alkyds: The most challenging to bring within GSO 1914 limits. Options: switch to waterborne alkyd emulsion (eliminates hydrocarbon solvent), use mineral spirits content reduction with reactive diluents, or position the product as an industrial coating (higher VOC limits apply).
- Two-pack epoxy and PU systems: Industrial coatings are subject to different (higher) VOC limits. However, for Vision 2030 LEED-specified projects, the project specification overrides SASO minimum limits — these projects often require <100 g/L VOC for protective coatings.
Sourcing Low-VOC Raw Materials from Raykem
Raykem supplies styrene-acrylic and pure acrylic emulsions specifically selected for low-VOC architectural paint formulation — including grades compatible with sub-30 g/L VOC interior flat formulations. Our solvent range includes monopropylene glycol (MPG) and butyl glycol, which have low vapour pressure and may be used in targeted quantities in waterborne systems with minimal VOC impact. Contact our Dubai or Riyadh team for formulation support and to request COA documentation confirming VOC content of specific raw materials.

Saudi Arabia applies GSO 1914 (Gulf Standardisation Organisation standard, adopted by SASO) which sets the following VOC limits: Interior flat/matt wall coatings — 30 g/L; Interior non-flat (eggshell/satin) — 150 g/L; Interior semi-gloss — 150 g/L; Interior gloss — 380 g/L; Exterior flat — 50 g/L; Exterior non-flat — 150 g/L; Exterior gloss — 250 g/L. These limits exclude water and apply to the coating as sold. Some Vision 2030 projects specify LEED-equivalent limits which are more stringent — typically 50 g/L for interior flat.
VOC content for SASO/GSO compliance is measured according to ISO 11890-2 (gas chromatography method) or ASTM D2369 (weight loss method at 110°C). The result is expressed as grams of VOC per litre of coating material as supplied (excluding water). Manufacturers must have their products tested by an accredited laboratory and maintain test records for SABER compliance. Laboratory testing can be done through SASO-accredited labs in Saudi Arabia or internationally accredited labs with results accepted by SABER.
The most effective VOC reduction strategies for alkyd systems are: (1) Replace conventional aromatic solvents (Xylene, Toluene) with Texanol ester alcohol — a high-boiling, low-VOC coalescent that can replace up to 50% of conventional solvent loading; (2) Switch to a water-reducible alkyd resin — these are modified to be dilutable with water rather than mineral spirit, cutting solvent VOC by 60–80%; (3) Use reactive diluents (e.g. propylene glycol diacetate) that are reactive with the binder and exempt from VOC classification in some standards; (4) Reformulate as a waterborne alkyd emulsion — the fully waterborne approach that eliminates hydrocarbon solvent entirely.
