The Rubber Authority of Thailand (EGAT-linked agency, กยท.), the Department of Agriculture and the Thai Rubber Association are working on screening rules for cup-lump rubber at buying points. Cup-lump made with the "white powder" coagulant shows plastic-like texture, a hard dry surface, poor elasticity and possible foreign matter. Expect stricter checks on rubber you buy or sell at collection points, and avoid or question any sales pitch for this coagulant. Watch for the final checklist and inspection guidance; no specific deadline has been announced yet.
