Rubber Authority of Thailand Targets 'White Substance' Usage
The Rubber Authority of Thailand (RAOT) is collaborating with agricultural and private sectors to curb the use of unauthorized chemicals in cup lump rubber production.
According to a report by Thai Post on August 14, 2026, the Rubber Authority of Thailand (RAOT) has initiated a crackdown on the use of an unauthorized chemical known as 'white substance' among rubber farmers. RAOT official Benjapol stated that the agency is partnering with the Department of Agriculture and private sector stakeholders to address the widespread application of this chemical in cup lump rubber production.
Authorities expressed concern that the 'white substance' alters the physical properties of the rubber, causing it to harden into a plastic-like texture. This degradation in quality poses a significant risk to the international reputation and standards of the Thai rubber industry. As a result, the coalition has reached a consensus to refuse the purchase of any rubber products treated with such improper chemicals.
For residents and those involved in the local agricultural economy, this move signals a stricter enforcement of quality control standards. While the immediate impact is focused on supply chain integrity, it highlights a broader effort to maintain Thailand's competitive edge in global rubber markets. It remains to be confirmed how the government plans to monitor small-scale farms effectively and what specific support or alternatives will be provided to farmers currently relying on these substances to ensure they can transition to approved methods without significant financial loss.
