# The 50 largest chemical companies in Belgium Tamtam tracks 146 chemical companies headquartered in Belgium. This list ranks the 50 largest by number of employees on LinkedIn, led by Solvay, Etex and Aliaxis. Their median headcount is 666. Half of them were founded in 1954 or later. The most common headquarters are Brussels (6), Zaventem (3) and Antwerp (2). This selection of Belgian companies primarily features large, established firms in chemical manufacturing, construction materials, and mining. Key players include Solvay, which develops chemical solutions for various industrial sectors, and Etex, a global manufacturer of building materials. Umicore focuses on materials technology for sustainable value, while Aliaxis specializes in advanced piping systems.

The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking.
