Reactivity is a key, mainly at the harvesting step. Flax is often harvested within a very short period, with specific equipment (encapsulating machines for seeds, flax harvester and turner binder for the straw).

Therefore COMLIN supports their producers so that they invest in harvesting equipments. Harvesting equipment is however expensive, since it is dedicated to flax only. Besides, each cooperative sets up a collective organization so as to support producers during harvesting works: sharing equipment between producers, coordinating harvesting works .
