About Somrak Rubber Industry Co., Ltd. - Raw Rubber Supplier in Thailand

Somrak Rubber Industry Co., Ltd. operates in Thailand and currently lists five active products. The catalogue covers two primary categories: raw rubber and textile waste. Within raw rubber the company offers Str20 Rubber, NR Block Rubber, NR Latex Off Specs, and Latex DRC HA. In the textile waste segment it supplies Waste Cotton Yarns. The product titles reflect standard industry designations for natural rubber grades and reclaimed cotton fibers.

The raw rubber items correspond to common natural rubber grades used in tyre and industrial applications, typically falling under HS chapter 40 (HS 4001). The latex variants are classified under HS 4002 for liquid latex, while the waste cotton yarns are generally coded under HS 6307 for textile waste. These categories are regularly exported from Thailand to markets in Southeast Asia, East Asia, and Europe, where manufacturers seek consistent quality and specification compliance.

Product Range and Specialties of Somrak Rubber Industry Co., Ltd.

Somrak’s catalogue includes Str20 Rubber, a natural rubber grade with a typical tensile strength of 20 MPa, used in general rubber compounding. NR Block Rubber refers to block‑shaped natural rubber, commonly supplied in 10 kg or 25 kg blocks for downstream processing. NR Latex Off Specs denotes latex that falls outside the standard specifications for purity or solid content, often sold for secondary applications such as flooring adhesives. Latex DRC HA is a high‑amine latex variant used in specialty coatings. The textile waste offering, Waste Cotton Yarns, consists of reclaimed cotton fibers generally graded by length (e.g., 30 - 40 mm) and moisture content below 12 % for recycling into non‑woven fabrics.

In the broader industry, natural rubber grades are evaluated by ISO 48‑4 for tensile strength, elongation, and hardness, while latex purity is measured by solid content percentage and pH. Textile waste fibers are frequently classified by ISO 105‑C06 for fiber length and ISO 14001 for environmental management of recycling processes. Buyers often request material safety data sheets (MSDS) and test reports aligned with these standards.

Trade and Export Information - Somrak Rubber Industry Co., Ltd.

Thailand is a major exporter of natural rubber, accounting for roughly 30 % of global raw rubber shipments, with primary destinations in China, Japan, the United States, and the European Union. Export shipments are typically packed in 20‑ft containers for block rubber and drums for liquid latex, using CIF or FOB terms. HS 4001 products require compliance with the EU REACH regulation and the US FDA standards for certain applications, while latex destined for medical use must meet USP specifications.

Textile waste such as reclaimed cotton yarns is exported mainly to textile manufacturers in Bangladesh, Vietnam, and Turkey that incorporate recycled fibers into non‑woven or blended fabrics. Trade documentation often includes a Certificate of Origin, phytosanitary certificates if applicable, and compliance with the OECD Guidelines for the Import of Waste. Buyers should verify that packaging meets ISPM 15 standards for wooden pallets used in container loading.

Sourcing from Somrak Rubber Industry Co., Ltd. - Buyer Guidance

When sourcing from Somrak, buyers should request a recent product specification sheet that details tensile strength, ash content, and moisture levels for each rubber grade, as well as a latex solid‑content analysis report. For textile waste, a fiber length distribution chart and a moisture content test result are standard verification documents.

It is advisable to obtain a third‑party laboratory test report, such as from SGS or Intertek, to confirm that the materials meet the relevant ISO or REACH criteria before contract finalization. Buyers should also confirm the packaging dimensions (e.g., 20 kg block size, drum capacity 200 L) and the lead time, which for Thai exporters typically ranges from 2 weeks to 1 month depending on order size.

What are the typical specifications for Str20 Rubber offered by Somrak?

Str20 Rubber is a natural rubber grade with a typical tensile strength of about 20 MPa, elongation at break around 500 %, and an ash content below 0.2 % as defined by ISO 48‑4.

How is NR Latex Off Specs different from standard latex?

NR Latex Off Specs refers to latex batches that fall outside the standard purity or solid‑content range, often having a lower dry rubber content (e.g., 45 % versus the usual 60 %) and are used in secondary applications such as flooring adhesives.

What packaging formats are used for the block rubber products?

Block rubber is usually packed in 10 kg or 25 kg wooden crates, wrapped in moisture‑resistant film, and loaded in standard 20‑ft containers for export.

Which certifications should a buyer request for the latex products?

Buyers typically ask for a Material Safety Data Sheet (MSDS), a recent REACH compliance statement, and a laboratory test report confirming solid content, pH, and microbial limits.

What are the common end‑uses for Waste Cotton Yarns?

Waste Cotton Yarns are commonly blended into non‑woven fabrics, used for insulation, geotextiles, or as reinforcement fibers in composite panels.

Which HS codes apply to Somrak’s main product categories?

Raw natural rubber products are generally classified under HS 4001, liquid latex under HS 4002, and reclaimed cotton yarns under HS 6307.

What is the typical lead time for an order from Thailand?

Exporters in Thailand usually require 2 weeks to 1 month from order confirmation to shipment, depending on product type and order volume.

What documents are needed for customs clearance of latex shipments?

Standard documents include the commercial invoice, packing list, Certificate of Origin, REACH compliance declaration, and, for liquid latex, a safety data sheet.
