# The 50 largest chemical companies in Grand Est

Tamtam tracks 108 chemical companies headquartered in Grand Est. This list ranks the 50 largest by number of employees on LinkedIn, led by Air Liquide Healthcare, Lesaffre and Clayens NP. Their median headcount is 126. Half of them were founded in 1974 or later. The most common headquarters are Strasbourg (3) and Colmar (2).

The companies listed operate in the Grand Est region, primarily within chemical manufacturing and wholesale building materials. While some are large groups like Air Liquide Healthcare, which provides home healthcare services and medical gases, and Lesaffre, focused on fermentation, the list also includes mid-sized firms. Soprema France specializes in innovative building products, and Butachimie produces Adiponitrile for plastics and textiles.

A notable pattern is the prevalence of companies in wholesale building materials, including KP1, a specialist in prefabricated building components, wienerberger France, providing building envelope solutions, and SEMIN, manufacturing construction materials. Many of these companies, such as Lesaffre, Soprema France, and SEMIN, have a long history, with founding dates stretching back to the late 19th and early 20th centuries.

## How this list is built

Every company on this list has a Tamtam company profile. 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. Last updated Nov 12, 2026.
