About Jinan Tonex Chemical Co.,Ltd - Optical Brighteners Supplier in China

Based in China, Jinan Tonex Chemical Co.,Ltd lists six active products in its catalogue. The company’s offerings fall under the broader categories of Optical Brightening Agents and Optical Brighteners, which are part of the chemicals and allied products sector. Each product is identified by a distinct trade name such as FP-127, OB-1, CBS‑X, SWN, Er‑i L (Ps‑1) and BA. The catalogue does not provide HS codes, so buyers must reference the general HS chapter for organic chemicals when arranging customs documentation. The supplier is classified in the harbor trust tier, indicating a baseline level of verification in trade platforms.

The six listed items are all variants of optical brightening agents used to enhance the whiteness of textiles, paper, and detergents. Product names suggest different chemical families, for example the “FP‑127” line and “CBS‑X” series, which are typical nomenclature for stilbene‑based brighteners. Buyers can expect these chemicals to be supplied as powders or liquid concentrates, common formats for this category. The catalogue’s focus on optical brighteners excludes other chemical families, keeping the product portfolio narrowly targeted. Potential importers should note that the supplier’s location in China aligns with the country’s large‑scale production of textile‑grade optical brighteners.

Product Range and Specialties of Jinan Tonex Chemical Co.,Ltd

Jinan Tonex Chemical Co.,Ltd’s catalogue comprises six optical brightening agents: FP‑127, OB‑1, CBS‑X, SWN, Er‑i L (Ps‑1) and BA. These products are typical of the stilbene‑type or coumarin‑type brighteners that deliver fluorescence under UV light, raising the perceived brightness of fabrics and paper. In the industry, optical brighteners are graded by fluorescence intensity, purity (often >99 %), and solubility in water or organic solvents. Common specifications include a maximum moisture content of 1 %, particle size below 100 µm for powder forms, and a UV‑absorption peak around 340‑380 nm.

Buyers of optical brighteners usually require compliance with REACH registration in the European Union and SDS (Safety Data Sheet) documentation. ISO 9001 quality management certification is a frequent prerequisite for large‑scale detergent manufacturers. The products may be offered in 25 kg drums, 500 kg bulk bags, or 20 ft containers, matching standard logistics for bulk chemicals. Typical grades are designated by trade names rather than numeric codes, but the industry distinguishes between high‑purity grades for textile finishing and lower‑purity grades for household detergent formulations.

Trade and Export Information - Jinan Tonex Chemical Co.,Ltd

Optical brightening agents produced in China are exported primarily to textile and detergent manufacturers in Southeast Asia, South Asia, Europe and North America. The HS chapter 29 (organic chemicals) is commonly used for customs classification of these compounds, and importers often cite HS 2905 for stilbene derivatives. Buyers generally request certificates of analysis (CoA), REACH registration numbers, and EU ECHA compliance documents before shipment.

Standard export practices for Chinese chemical suppliers include FOB or CIF terms, with cargo packed in sealed drums or bulk bags on 20 ft or 40 ft containers. Temperature‑controlled shipping is not usually required, but moisture‑proof packaging is essential to maintain product stability. Inspection agencies such as SGS or Bureau Veritas are frequently engaged for pre‑shipment sampling, especially when large volumes are ordered. The supplier’s harbor trust tier suggests that basic verification of business credentials is available on trade platforms.

Sourcing from Jinan Tonex Chemical Co.,Ltd - Buyer Guidance

When sourcing optical brightening agents from Jinan Tonex Chemical Co.,Ltd, buyers should request the latest Certificate of Analysis, Safety Data Sheet, and REACH registration proof for each product. Verification of purity (≥99 %) and fluorescence intensity specifications helps confirm suitability for textile or detergent applications. Samples are typically supplied in 500 g quantities, allowing laboratory testing before committing to bulk orders.

Buyers should also confirm packaging details, such as whether the product is delivered in 25 kg drums or bulk bags, and ensure that the agreed Incoterm (FOB or CIF) aligns with their logistics strategy. It is advisable to ask for a pilot production run or a small‑batch trial to assess compatibility with existing formulations. Reviewing the supplier’s inspection reports and any third‑party lab results can reduce risk before finalizing a contract.
