Natural Rubber Prices

RSS3 (Ribbed Smoked Sheet Grade 3) is the global benchmark for natural rubber. It is made from fresh field latex that is coagulated, pressed into thin sheets, and smoked in wood-fired smokehouses. The smoking process preserves the rubber and gives it a distinctive amber color. RSS3 is the most widely traded grade on the SGX SICOM exchange and commands a premium over technically specified grades because of its consistency and suitability for high-quality end products including medical gloves, condoms, and precision rubber goods.

TSR20 (Technically Specified Rubber 20) is block rubber produced from cup lump, tree lace, and field coagulum -- the lower-grade raw materials collected from rubber plantations. Unlike RSS which is graded visually, TSR grades are determined by laboratory testing for dirt content (the "20" means a maximum 0.20% dirt by weight), ash content, nitrogen, and volatile matter. TSR20 is the workhorse of the tire industry and accounts for the majority of global natural rubber consumption.

SMR (Standard Malaysian Rubber) grades follow the same technical specification system as TSR but are specific to Malaysian production. SMR CV (Constant Viscosity) commands the highest premium due to its consistent processing characteristics. SMR L (Light) is a pale-colored grade used in products where color matters. SMR 5, 10, and 20 differ by dirt content tolerance.

Why the price difference? RSS3 typically trades at a 15-25% premium over TSR20. This spread reflects the higher raw material cost (fresh latex vs. cup lump), more labor-intensive processing, and the quality premium demanded by manufacturers of medical and consumer products. When the spread narrows, it often signals tightness in the cup lump supply or weakness in tire demand.

Global natural rubber production exceeds 14 million tonnes annually. Thailand leads with approximately 4.78 million tonnes (32% of global output), concentrated in the southern provinces of Surat Thani, Nakhon Si Thammarat, and Songkhla. Indonesia follows at 3.55 million tonnes (24%), primarily from Sumatra and Kalimantan.

Ivory Coast has emerged as the world's third-largest producer and the dominant force in African rubber, reaching 1.68 million tonnes in 2023 -- a tenfold increase from 164,000 tonnes in 2005. The country's rubber sector, regulated by APROMAC, targets 2.5 million tonnes annually by 2033. Rubber accounts for approximately 20% of Ivory Coast's GDP. Major processing facilities include SAPH, SOGB, and LCC in Abidjan.

Vietnam produces 1.33 million tonnes, China 877,000 tonnes (though it consumes far more than it produces), and India 876,000 tonnes centered on Kerala state. Malaysia, once the world's largest producer, now produces approximately 600,000 tonnes as plantations have been converted to palm oil.

Tapping seasons vary by region. In Thailand, the main tapping season runs from May through January, with a "wintering" period from February to April when trees shed leaves and yield drops. Southeast Asian monsoon seasons (October-December) can disrupt collection and logistics, causing seasonal price spikes.
