Standard Indonesian TSR bales graded to SNI 1903 for tire and industrial compounders.
Technically Specified Rubber in 35 kg bales is how most Indonesian natural rubber reaches overseas tire plants and industrial compounders. Our TSR programme covers SIR 10 premium lots, high-volume SIR 20 tire grade, and SIR CV constant-viscosity bales for applications where Mooney drift would disrupt automated mixing. Every lot below is tested to SNI 1903 limits with retained samples and a specification sheet tied to the export reference.

Tire makers blend SIR 20 as a workhorse grade in passenger and light-truck compounds. Premium tread and thin-gauge lines often specify SIR 10 for lower dirt and ash. Industrial buyers running conveyor belts, moulded goods, or adhesive lines choose SIR CV when they need Mooney viscosity to stay inside a narrow band across production shifts. All three ship as shrink-wrapped 35 kg bales on export pallets.
Each bale lot is sampled for dirt content, ash, volatile matter, nitrogen where applicable, Plasticity Retention Index (PRI), and Mooney viscosity ML (1+4) at 100 °C. Results are compared against SNI 1903 grade tables and your purchase specification before stuffing. Out-of-spec bales are segregated rather than blended into export lots, and laboratory records travel with the commercial invoice.
A standard 20 ft container carries 19.6 MT (560 bales) on shrink-wrapped pallets. We load FOB Jakarta or Belawan with certificate of origin, commercial invoice, packing list, weight and quality certificates, and loading photos. Dry containers with adequate ventilation are standard; reefer is not used for solid rubber bales.
Ordering, testing, and shipping Indonesian TSR bales for wholesale buyers.
Tire compounders, industrial rubber manufacturers, and trading houses that blend Indonesian SIR grades into passenger, light-truck, and general-purpose recipes. TSR bales suit plants with internal mixing lines that want SNI 1903 limits confirmed lot by lot before the mixer.
Dirt content, ash, volatile matter, nitrogen on applicable grades, PRI, and Mooney viscosity ML (1+4) at 100 °C against SNI 1903 tables. Out-of-spec bales are segregated rather than blended upward, and retained samples are held against the contract reference.
Standard MOQ is 19.6 MT, one 20 ft container with 560 bales of 35 kg each on shrink-wrapped pallets. Lead time is typically two to three weeks FOB Jakarta or Belawan for catalogue grades, longer on SIR CV scheduled production.
Jakarta and Belawan are our primary FOB points for Sumatra and Java mill supply. Palembang is available for southern Sumatra programmes when vessel schedules align. We quote FOB, CFR, or CIF to your destination port.
