ISO Certified
At Whechemical, quality assurance is embedded into every stage of our operation — from raw material sourcing to final product dispatch. Our manufacturing processes are governed by internationally recognized management systems, and every batch leaving our facility is traceable, tested, and certified to meet your formulation requirements.
We maintain full compliance with European and international construction chemical standards, including EN 12004 and EN 998 series, and our products are regularly audited by independent third-party laboratories to confirm consistency and performance.
Whechemical products and processes are verified against the most rigorous international standards in quality, environmental management, and chemical safety.
Our entire production and supply chain operates under ISO 9001:2015 certified quality management. This covers process control, customer satisfaction, and continuous improvement across all business functions.
Certified to ISO 14001:2015, we systematically identify and manage our environmental impact — reducing waste, controlling emissions, and continuously improving our ecological performance.
All Whechemical products are fully compliant with EU REACH regulation (EC 1907/2006). Safety Data Sheets are available for all products and are kept up to date in line with regulatory updates.
Our cellulose ethers and polymer powders are formulated and tested to support compliance with EN 12004 (tile adhesives) and EN 998 (mortars) classification requirements for C1, C2, F and S class systems.
Relevant Whechemical products carry CE marking, confirming conformity with applicable European Directives and harmonised standards for use in construction applications across EU member states.
Every production batch undergoes full in-house quality control testing — including viscosity, moisture content, particle size, and application performance — before release for dispatch.
Every Whechemical product passes through a rigorous quality chain before it reaches you.
Every incoming raw material is sampled and tested against specification before being admitted to our production facility. Suppliers are regularly audited and rated.
Critical process parameters are monitored and recorded throughout production. Any deviation triggers a hold and review before the batch proceeds.
Each batch is tested in our in-house laboratory against the full product specification — viscosity, moisture, particle size, and application performance.
Approved batches receive a Certificate of Analysis, a Safety Data Sheet, and a unique batch number for full traceability from production to end-use.
Our quality systems and product performance data are independently verified by accredited third-party laboratories on a regular scheduled basis.
