Import Dimethyl-5-Sulfoisophthalate Sodium Salt — Buy in Bulk from Supplier in China

Dimethyl-5-sulfoisophthalate sodium salt from Shandong Haihua Tianhe Organic Chemical Co., Ltd is described as a high-purity industrial chemical with a minimum purity of 98%. It is used primarily as a comonomer in cation-modified polyester fibres to enhance dye uptake and colour vibrancy. The compound is water-soluble and thermally stable, making it suitable for use in aqueous resin systems for coatings and adhesives. Its molecular structure includes a sulphonate group that enables strong interaction with cationic dyes.

The product is marketed as non-toxic and compliant with industrial safety standards, though no specific certifications are listed. It is typically used in textile manufacturing where consistent dye penetration and fibre softness are required. The supplier does not provide grade distinctions (A/B) or detailed impurity limits beyond purity and solubility. Industry-standard impurity thresholds for sulphate, iron, and acid value are assumed but not confirmed in the listing.

Buyers in the synthetic fibre and polymer industries source this material for modifying PET chips and formulating waterborne resins. Packaging is not specified in the listing, but standard industry practice uses 25 kg multi-layer bags or bulk containers. Trade terms such as FOB and CIF are mentioned, but exact MOQ, lead time, and payment terms are not stated. Buyers must request these details directly from the supplier before proceeding.

Shandong Haihua Tianhe Organic Chemical Co., Ltd is located at 919, Yuanfei Road, Weifang, China. The supplier is classified as an imported exporter with harbor trust tier status, indicating documented export activity. The profile does not disclose years in business, production volume, laboratory facilities, or client references. Response metrics are not available, and no certifications are claimed beyond general references to ISO and SGS, which are not verified in the listing.

The company presents itself as a producer of organic chemical intermediates for industrial applications. While the listing mentions compliance with international standards, it provides no evidence of third-party testing, audit reports, or quality control procedures. Buyers should treat this as a supplier with export capability but must independently validate technical claims and compliance documentation before procurement.
