Cup lump is one of the four types of field coagula collected from the rubber tree, others being, tree lace, earth scrap and small holders lump. Cup lump refers to the small amount of latex that drips in to the cup even after the collection of latex. According to Jose K. Mani, MP, the cup lump is priced about ₹60 a kg. In addition to the devastation of the rubber industry, the import of cup lump along with the water content would also lead to major environmental problems. He said the manufacturers had approached the office of the Prime Minister seeking the green signal for the import of cup lump rubber.
