Standard Indonesian Rubber (SIR)
Description
Indonesia’s rubber cultivation area exceeds 3 million hectares. Indonesia produces 2 million tonnes of rubber per year in North and South Sumatra, Riau, Jambi and West Kalimantan, placing the country second place in world rubber production after Thailand. Primarily for the tyre industry, 85% of Indonesia’s rubber output is exported, mainly to Singapore, China, Japan, USA and Brazil.
While exports are high, domestic consumption of rubber is low: presently, Indonesia relies on processed rubber products from abroad due to its underdeveloped processing and manufacturing plants. Indonesia’s yield per hectare is also lower compared to other top rubber producers, due to the generally older rubber trees it has, as well as low investment capabilities of its farmers.
