The manufacturers in Luxembourg are mostly large and mid-sized firms operating in diverse industrial sectors. Steel and metal processing are prominent, as seen with ArcelorMittal, a global leader in steel and mining, and Aperam, a stainless steel company. Food and beverage manufacturing is also well-represented by companies like Ferrero, a confectionery producer, and Unternehmensgruppe Theo Müller, a family-owned food group. Other significant players include PM International in health and beauty products, and FANUC Europe, which provides automation solutions.
Most of these companies have substantial workforces, indicating established operations. A notable pattern is the geographic distribution of headquarters, with a concentration in Luxembourg City itself, but also several in smaller surrounding municipalities such as Senningerberg, Bertrange, and Echternach, suggesting a distributed industrial base across the Grand Duchy.

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 11, 2026.
