# Top 26 manufacturers in the Manche department

Tamtam tracks 26 manufacturers headquartered in the Manche department. This list ranks all of them by number of employees on LinkedIn, led by EFINOR, Les Maîtres Laitiers du Cotentin and CTI. Their median headcount is 53. Half of them were founded in 1983 or later.

The Manche department hosts a concentration of manufacturing companies, predominantly in industrial machinery and food processing. Many are mid-sized firms, with a few larger groups like EFINOR, specializing in metal working, and Les Maîtres Laitiers du Cotentin, processing milk into dairy products. CTI manufactures custom welded assemblies, while TRICOTS SAINT-JAMES produces traditional knitwear.

A notable pattern is the strong presence of food and beverage manufacturers, such as Elle & Vire - Groupe Savencia, known for dairy creams, and Priméale France & International, a major player in fresh vegetables. Industrial machinery manufacturers like RABAUD, producing forestry and construction equipment, also form a significant cluster, with several companies headquartered in Cherbourg-en-Cotentin.

## 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.
