The list is not conclusive but includes, . dyes and pigments, plant health products and biocides, pharmaceutical products (chemical and biological processes), organic explosives, organic intermediates, specialised surfactants, flavours, fragrances, pheromones, plasticisers, vitamins, optical brighteners and flame- retardants. No specific threshold was established in drawing a borderline to large volume production. Therefore it is implied that an OFC production site may also include.
