1. Definition
RSS3 (Ribbed Smoked Sheet grade 3) is a form of natural rubber sheet produced from natural latex. The latex is coagulated, ribbed through rolling, and dried in smokehouses at temperatures of approximately 50–60°C.
RSS3 is the most widely traded grade within the Ribbed Smoked Sheet category and serves as the benchmark contract traded on the Tokyo Commodity Exchange (TOCOM) under the ticker TRU.
2. Key Technical Characteristics
- Origin: Natural rubber
- Form: Ribbed sheets, yellowish-brown color
- Drying method: Smoke-drying process
- Primary applications: Tire manufacturing and industrial rubber products
- Main trading market: Tokyo Commodity Exchange (Japan)

II. RSS3 Supply Chain and Production
1. Major Producing Regions
- Thailand (largest producer globally)
- Indonesia
- Malaysia
- Vietnam
These three leading producers account for approximately 60% of global natural rubber output.
2. Basic Production Process
- Step 1: Latex tapping from rubber trees
- Step 2: Coagulation of latex into sheets
- Step 3: Ribbed rolling to form structured sheets
- Step 4: Smoke-drying in smokehouses
- Step 5: Quality grading (RSS1 – RSS5)
III. Factors Influencing RSS3 Prices
1. Supply and Demand
- Rubber trees have a long biological growth cycle (5–7 years)
- Making short-term supply adjustments difficult.
- Inventory levels and stockpile data therefore have a significant impact on market pricing.
2. Weather and Seasonal Cycles
- Dry season (late year – February): production declines
- Rainy season (from February onward): production increases
→ Prices typically rise during the dry season and soften during the rainy seasondue to supply fluctuations.
3. Automotive Industry
- The tire industry represents the largest source of global rubber demand.
- Automobile production and sales—particularly in China—have a direct impact on RSS3 consumption and pricing.
4. Crude Oil and Synthetic Rubber Prices
- When crude oil prices increase → production costs of synthetic rubber rise.
- Natural rubber (RSS3) therefore becomes more competitive and attractive as an industrial input.

IV. RSS3 Trading on TOCOM
1. Purpose of Futures Contracts
- Price hedging for industrial enterprises
- Inventory management for commodity traders
- Investment and speculative opportunities for financial market participants
2. Key Market Indicators to Monitor
- Rubber inventories in China and Japan
- Open Interest and fund positioning
- Automobile and tire production data
- Weather conditions in Thailand and Indonesia
- USD exchange rate fluctuations
V. Strategies for Effective RSS3 Investment
1. Understanding the Product and Contract Specifications
- Investors should develop a comprehensive understanding of RSS3 as a global industrial commodity, including its physical characteristics (elasticity, mechanical durability), quality grading, primary applications (tires, automotive components, and industrial rubber products), and its role within the global tire manufacturing supply chain.
- A solid understanding of the RSS3 (TRU) futures contract traded on the Tokyo Commodity Exchange (TOCOM) is also essential. This includes contract size, price quotation unit, minimum price fluctuation, delivery months, delivery locations, and trading hours.
- Key market indicators for RSS3 include:
o Open Interest and positioning of investment funds.
o Certified RSS3 warehouse inventories
o Automobile and tire production in major consuming countries (China, India, Thailand)
o Term structure of futures prices (contango/backwardation)
o Exchange rate fluctuations, particularly USD
→ Monitoring these indicators helps investors assess supply–demand dynamics and identify short- to medium-term price trends in the RSS3 market.
2. Utilizing Hedging and Risk Management Tools
RSS3 (TRU) futures contracts play an important role for:
- Tire manufacturers and processors: Locking in raw material prices to protect operating margins from natural rubber price volatility.
- Rubber exporters and commodity traders: Managing price risks associated with physical rubber trading and transportation timelines.
- Investment funds and financial investors: Capturing price volatility in RSS3 while diversifying and managing risks within commodity portfolios.
3. Monitoring Key Drivers of RSS3 Price Movements
- RSS3 prices are particularly sensitive to:
o Weather conditions in major producing regions (Thailand, Indonesia, Malaysia)
o Production disruptions caused by prolonged rainfall, pests, or labor issues
o Political developments and rubber export policies
o Exchange rate volatility, particularly USD
o Global automobile production and tire demand
- Investors should regularly monitor:
o Periodic rubber inventory and export reports
o Weather indicators such as rainfall levels, droughts, and extreme climate events
o Automobile and tire production statistics in major markets
o Policy announcements and export directives from leading rubber-producing countries
→ Continuous monitoring of these factors enables investors to better evaluate RSS3 market fundamentals and price trends across different market cycles.
