• Multi-year deal to supply about 200,000 dry metric tons a year of caustic soda

• TA’ZIZ will be first major domestic supplier of caustic soda to EGA

• In support of Make it in the Emirates initiative, deal strengthens resilience and supports UAE industrial self-sufficiency

• TA’ZIZ set to produce over 700,000 dry metric tons of caustic soda annually by 2028, placing it in the top three single site producers globally

United Arab Emirates, 6 May, 2026: TA’ZIZ and Emirates Global Aluminium (EGA) today announced a strategic agreement for the long-term supply of about 200,000 dry metric tons per year of caustic soda, a critical raw material used in alumina refining.

Signed during the Make it in the Emirates Forum, the agreement positions TA’ZIZ as the first major supplier of domestically produced caustic soda to EGA’s Al Taweelah alumina refinery in the Khalifa Economic Zone Abu Dhabi (KEZAD). The deal will come into effect in Q4 2028, with an option to expand supply if EGA’s requirement increases.

The deal reinforces the resilience of the UAE’s industrial sector by reducing import dependency, strengthening supply chain security and business continuity, boosting local industrial self-sufficiency, and accelerating the United Arab Emirates’ economic diversification.

Mashal Al Kindi, CEO of TA’ZIZ, said: “The agreement to supply locally produced caustic soda to the world’s largest premium aluminum producer underpins the role of TA’ZIZ as a national engine of sustainable industrial growth. By 2028, TA’ZIZ will have the infrastructure in place to deliver 4.7 million tonnes per annum (mtpa) of chemicals, creating long-term value for our partners, industries and the wider economy. We will continue to strengthen supply chain resilience and support the UAE’s journey toward industrial self-sufficiency.”

Abdulnasser Bin Kalban, CEO of EGA, said: “EGA has long championed industrialization and economic diversification in the UAE and the aluminum sector, with EGA at its heart, which accounts for 1.3% of the UAE economy and supports over 56,000 UAE jobs. Each year, we spend more than AED8 billion on goods and services from UAE suppliers. Securing a key raw material, like caustic soda, locally strengthens our supply chain and increases our economic impact. We are pleased to partner with TA’ZIZ on this important initiative and look forward to continued collaboration.”

Caustic soda will be produced at the TA’ZIZ chlor-alkali plant, part of a 1.9 mtpa vinyl complex that includes production of ethylene dichloride (EDC), vinyl chloride monomer (VCM) and polyvinyl chloride (PVC). The chlor-alkali unit will produce over 700,000 dry metric tons per year, placing TA’ZIZ among the top three chlor-alkali plants globally by capacity. The broader TA’ZIZ Industrial Chemicals Zone also includes a 1 mtpa ammonia plant and a 1.8 mtpa methanol plant, reinforcing Ruwais’ position as a global hub for industrial chemical production.

TA’ZIZ will produce the caustic soda alongside ethylene dichloride (EDC), vinyl chloride monomer and polyvinyl chloride in its polyvinyl value chain. Caustic soda plays a key role in the chlor-alkali process, where it is produced alongside chlorine and hydrogen. The chlorine generated is then used to produce VCM, which is made into a polymer to form polyvinyl chloride, a plastic used extensively in construction, healthcare and industrial applications.
