Natural Rubber SIR20 Price FOB Indonesia 2026
Natural Rubber SIR20 FOB Price Indonesia 2026: Current Market Overview
Natural rubber SIR20 from Indonesia is an actively traded internationally priced commodity with daily price movements tracked against the SICOM TSR20 futures contract on the Singapore Commodity Exchange. Unlike fixed-price agricultural commodities, SIR20 FOB prices from Indonesia fluctuate with global rubber market conditions — supply from major producing countries, demand from tire and industrial rubber manufacturers, macroeconomic factors affecting industrial output, and currency movements in rubber-producing nations.
In 2026, Indonesian SIR20 FOB prices are trading in the range of approximately USD 1.92 to USD 2.16 per kilogram FOB Belawan or Tanjung Priok. This range reflects current global natural rubber market conditions — tightened supply from Southeast Asian producing countries due to panel disease pressure and replanting programs, steady demand from Chinese and Indian tire manufacturers, and a broadly supportive macroeconomic environment for industrial commodity demand. At a net weight of approximately 20 metric tons per 20ft container, the total FOB value per container in this price environment is approximately USD 38,400 to USD 43,200.
Buyers who are new to natural rubber procurement should understand that the FOB price range quoted here is indicative of current market conditions and will move — sometimes significantly — with SICOM TSR20 futures price changes. All firm FOB price quotations from Global Spice Trade are valid for a defined period (typically 3–7 business days) and are based on SICOM TSR20 at the time of quotation plus an agreed basis differential.
How Indonesian SIR20 FOB Price Is Structured
Understanding how Indonesian SIR20 FOB prices are formed and quoted helps buyers negotiate effectively and evaluate whether a quotation from an Indonesian exporter is commercially reasonable relative to current market conditions.
The SICOM TSR20 Benchmark
The Singapore Commodity Exchange (SICOM) TSR20 contract is the primary international price benchmark for Technically Specified Natural Rubber Grade 20 from Southeast Asia. SICOM TSR20 is a physically delivered futures contract with delivery in Singapore — the price reflects the market consensus on the value of TSR20-grade rubber delivered to Singapore, which is the primary regional rubber trading and distribution hub.
Indonesian SIR20, Thai STR20, and Malaysian SMR20 — all TSR20-equivalent grades from their respective countries — are priced in international trade relative to the SICOM TSR20 benchmark. The FOB price from Indonesia is typically quoted as SICOM TSR20 (nearby month futures price) plus or minus a basis differential that reflects the quality differential between the specific Indonesian lot and the TSR20 contract specification, logistics cost from Indonesian origin to Singapore, current supply and demand dynamics in the Indonesian market, and the exporter's commercial margin.
Basis Differential
The basis differential for Indonesian SIR20 versus SICOM TSR20 has historically ranged from approximately minus USD 0.05/kg to plus USD 0.10/kg, depending on market conditions. When Indonesian rubber supply is relatively tight — as has been the case in 2025–2026 due to replanting programs reducing tappable area in key production provinces — the basis tends to be positive, meaning Indonesian SIR20 is priced at a modest premium to the SICOM benchmark. When Indonesian supply is ample relative to demand, the basis may be flat or slightly negative. Buyers who monitor both SICOM TSR20 futures and the Indonesian basis differential are well-positioned to identify favorable procurement windows.
Price Validity Period
Given the daily price movements in natural rubber markets, FOB price quotations for SIR20 from Indonesian exporters are valid for a limited period — typically 3 to 7 business days from the date of quotation. Buyers should be prepared to make purchase decisions within this validity window or accept repricing based on current SICOM TSR20 at the time of order confirmation. Forward purchase contracts — which fix the FOB price for future delivery — are available for buyers with a defined monthly volume requirement and willingness to commit to a delivery schedule, providing price certainty in exchange for volume commitment.
SIR20 Price Comparison: Indonesia vs Thailand vs Malaysia
Indonesia, Thailand, and Malaysia are the three largest natural rubber exporting countries, and buyers typically monitor FOB prices from all three origins when evaluating sourcing options. Understanding the competitive pricing dynamics between these origins helps buyers identify when Indonesian SIR20 offers the best value on a total landed cost basis.
Indonesia vs Thailand
Thai STR20 (Standard Thai Rubber Grade 20) is the direct equivalent of Indonesian SIR20 and the world's largest volume TSNR grade in international trade. SICOM TSR20 is effectively a Thailand-anchored price given Thailand's dominant market share in global TSNR trade. Indonesian SIR20 FOB prices typically track closely to Thai STR20 FOB prices, with the basis differential reflecting current supply and logistical conditions in each country. For Chinese buyers — the largest market for both Thai and Indonesian rubber — landed cost from Indonesia is typically comparable to or slightly lower than from Thailand given Indonesia's geographic proximity to South China ports and efficient Belawan port connections.
Indonesia vs Malaysia
Malaysian SMR20 is produced in smaller volumes than Thai STR20 or Indonesian SIR20 and has historically commanded a slight quality premium in some technical markets due to Malaysia's long-established rubber processing standards and the MRRDB (Malaysian Rubber Research and Development Board) technical support infrastructure. However, Malaysian rubber production has declined significantly over the past decade due to plantation conversion to palm oil, reducing Malaysia's competitive position as a high-volume SIR20 source. Indonesian SIR20 is now more competitively priced than Malaysian SMR20 for most applications and represents better value for buyers who do not have a specific Malaysian origin requirement.
Key Factors Driving SIR20 Price in 2026
Natural rubber is a globally traded commodity with prices influenced by a complex interaction of supply, demand, macroeconomic, and financial market factors. The following are the primary drivers of SIR20 price movement in 2026.
Supply from Major Producing Countries
Thailand, Indonesia, and Vietnam together account for approximately 65–70% of global natural rubber production. Supply disruptions in any of these origins — from weather events, panel disease pressure (particularly in Thailand and Indonesia), labor availability issues, or government policy changes affecting smallholder farming — can drive significant price increases by reducing available export volumes against stable demand. In 2026, ongoing replanting programs in key Indonesian rubber-producing provinces in South Sumatra and Riau have reduced the proportion of mature tappable trees in plantation areas, contributing to tighter supply relative to historical levels and supporting the price in the USD 1.92–2.16/kg FOB range.
Chinese Tire and Automotive Demand
China's tire manufacturing sector is the single largest consumer of natural rubber globally, and changes in Chinese tire production output are the most powerful demand-side driver of global natural rubber prices. Periods of strong Chinese automotive production — driven by domestic passenger vehicle demand and export growth from China's rapidly expanding electric vehicle manufacturing sector — support natural rubber prices. Slowdowns in Chinese industrial output or automotive production have historically triggered the most significant natural rubber price corrections. Buyers who monitor Chinese monthly tire production data and automotive output statistics are tracking the primary demand-side indicator for natural rubber price direction.
Synthetic Rubber Price Competition
Natural rubber competes directly with synthetic rubbers — primarily styrene-butadiene rubber (SBR) and polybutadiene rubber (BR) — in many compound formulations where the performance requirements can be met by either natural or synthetic alternatives. When crude oil prices are low, synthetic rubber prices fall and the price premium of natural rubber over synthetic alternatives widens, incentivizing compound formulators to increase synthetic rubber proportions in their blends — reducing natural rubber demand and creating downward price pressure. Conversely, when crude oil prices are high, synthetic rubber prices rise, making natural rubber more competitive and supporting demand.
Currency: IDR and THB vs USD
Indonesian rubber is priced in USD, but production costs are in Indonesian Rupiah. When the Rupiah weakens against the USD — the broad direction over the medium term — Indonesian rubber production costs in USD terms fall, giving Indonesian exporters more flexibility to price competitively in USD while maintaining Rupiah profit margins. Buyers who track the IDR/USD exchange rate can identify periods when Indonesian exporters face less cost pressure and may be more willing to negotiate favorable basis differentials.
EUDR and Sustainability Premium
The EU Deforestation Regulation (EUDR) is introducing a compliance cost layer for Indonesian rubber exporters who supply European buyers — requiring investment in traceability systems, geolocation data collection, and third-party deforestation verification. These compliance costs are beginning to be reflected in a modest sustainability premium for EUDR-compliant Indonesian rubber lots relative to non-compliant product. Buyers who purchase for European end-markets should anticipate a 1–3% price premium for fully EUDR-compliant Indonesian SIR20 relative to standard product.
Total Landed Cost: From FOB to Your Warehouse
For buyers evaluating the economics of sourcing Indonesian SIR20, the FOB price is the starting point — several additional cost components must be added to arrive at total landed cost at the buyer's facility.
Ocean Freight
Ocean freight for a 20ft container of palletized SIR20 bales from Belawan (North Sumatra) to major destination ports ranges approximately as follows in current market conditions: to Shanghai or Guangzhou (China) approximately USD 300–500 per container; to Chennai or Nhava Sheva (India) approximately USD 400–700 per container; to Hamburg or Rotterdam (Europe) approximately USD 1,200–2,000 per container; to Jebel Ali (Dubai, UAE) approximately USD 600–900 per container. These rates are indicative and fluctuate with container freight market conditions — buyers should obtain current freight quotes from their freight forwarder for specific route pricing at the time of procurement planning.
Import Duty
Import duty on natural rubber SIR20 (HS 4001.22) varies by destination country: China applies a 20% MFN import duty with ASEAN FTA rate of 0% for Indonesian origin under the ASEAN-China FTA; India applies an import duty of 25% MFN with concessional rates under AIFTA; EU applies 0% import duty under the EU-Indonesia CEPA (once ratified) or existing GSP arrangements; Japan and South Korea have 0% or near-zero import duty under bilateral FTAs with Indonesia. Buyers should confirm the applicable import duty rate and any FTA preferential rate for their specific destination with their customs broker before purchase, as the duty differential between MFN and FTA rates can be commercially significant.
Forward Contracts and Price Risk Management for SIR20
For buyers with regular monthly volume requirements, forward purchase contracts with price fixation provide protection against adverse price movements between the order date and delivery month. A forward contract fixes the FOB price for a defined volume and delivery window — typically 1–3 months forward — in exchange for a volume commitment and deposit payment from the buyer.
Forward contracts are particularly valuable for rubber buyers who supply fixed-price manufacturing contracts to their own customers — locking in raw material cost for the duration of a supply contract eliminates the risk of margin erosion from natural rubber price increases after a manufacturing price has been committed. Buyers who process SIR20 into finished rubber goods for fixed-price delivery contracts should evaluate whether forward price fixation is appropriate for their risk management strategy.

What is the current FOB price for Natural Rubber SIR20 from Indonesia in 2026?
Indonesian SIR20 FOB prices in 2026 are trading in the range of approximately USD 1.92 to USD 2.16 per kilogram FOB Belawan or Tanjung Priok. At 20 MT net weight per 20ft container, this represents a total FOB value of approximately USD 38,400 to USD 43,200 per container. These prices are indicative and move with SICOM TSR20 futures. Contact our team for a current valid FOB quotation based on today's SICOM TSR20 price.
How is Indonesian SIR20 FOB price determined relative to SICOM TSR20?
Indonesian SIR20 FOB prices are quoted as SICOM TSR20 (nearby month futures price at the time of quotation) plus or minus a basis differential. The basis differential reflects quality, logistics, and current supply-demand factors — typically ranging from minus USD 0.05/kg to plus USD 0.10/kg in current market conditions. A quotation should always specify the SICOM reference price date and the basis being applied so you can evaluate fairness relative to current market conditions.
How long is an SIR20 FOB price quotation valid?
FOB price quotations for SIR20 are typically valid for 3 to 7 business days from the date of issue, reflecting the daily movement of SICOM TSR20 futures prices. Buyers should be prepared to confirm purchase orders within this validity window. If the validity period expires without order confirmation, a revised quotation based on current SICOM TSR20 will be issued. Forward contracts with fixed prices for future delivery windows are available for buyers with confirmed monthly volume requirements.
What is the total FOB value per 20ft container of SIR20 at current prices?
At current FOB prices of USD 1.92–2.16/kg and a net weight of approximately 20 MT (20,000 kg) per 20ft container, the total FOB value per container is approximately USD 38,400 to USD 43,200. At 22 MT per 40ft container, the total FOB value is approximately USD 42,240 to USD 47,520. These values serve as planning references — final FOB value is confirmed in the proforma invoice based on actual net weight and the FOB price agreed at the time of order confirmation.
Are bulk discounts available for SIR20 orders above one container?
SIR20 pricing is primarily market-referenced rather than volume-discounted in the same way as fixed-price agricultural commodities. However, buyers who commit to regular monthly volumes — typically 3 or more containers per month — can negotiate a more favorable basis differential (lower premium above SICOM TSR20) and priority lot allocation during periods of tight supply. Forward supply agreements that fix the volume and price basis for 3–6 months provide both parties with planning stability and typically result in more competitive pricing than spot purchases.
Does the FOB price include the TSNR Certificate of Analysis?
Yes. The FOB price for Indonesian SIR20 from Global Spice Trade includes a TSNR Certificate of Analysis covering all six SIR20 specification parameters — dirt content, ash content, nitrogen content, volatile matter, PRI, and Wallace Plasticity Po — tested by an accredited laboratory. Certificate of Origin and standard export documentation are also included. Optional third-party pre-shipment inspection from SGS or Bureau Veritas can be arranged at the buyer's cost if independent quality verification is required for their procurement compliance process.
