Mandatory Requirement: Products lacking this certification will not be able to clear customs or be sold in GCC member states.

Tiered Management: The certification is divided into several efficiency grades (e.g., 1 to 5 stars) based on the product's water consumption per unit of time. This provides consumers with clear guidance for selection and creates a platform for high-quality products to compete through differentiation.

Mark of Trust: Products bearing the GSO Water Efficiency label signify that their performance and quality meet the highest standards in the Gulf region, serving as a key factor in winning the trust of both governments and consumers.
