Standard Thai Rubber (STR)
Description
Thailand is the undisputed global leader in natural rubber , consistently ranking as the world's top producer and exporter. With a massive cultivation area of over 3.5 million hectares, the nation produces nearly 5 million metric tons annually, accounting for over 30% of the world's total supply.
Thai products are graded under the internationally recognized Standard Thai Rubber (STR) system, with grades like STR20 being a benchmark for quality and consistency in manufacturing.
Further strengthening its industry, Thailand is actively boosting its domestic processing capabilities through strategic initiatives like the “ Rubber City ” industrial hub. With domestic consumption now accounting for nearly 20% of its output, Thailand is a powerhouse for both raw rubber and increasingly, for high-value finished rubber goods.
