About Yixing Xinyu Chemicals Co., Ltd. - Laboratory Chemicals Supplier in China

Yixing Xinyu Chemicals Co., Ltd. is based in China and lists six active products in its catalogue. The company classifies its offerings under Laboratory Chemicals, Chemicals & Allied Products, Cosmetic Chemicals and Laboratory Reagents. The listed items include several sulfonated aromatic amines such as 2,5‑diaminotoluene sulfate and P‑phenylenediamine, as well as hydroxy‑ethyl substituted derivatives. Each product is identified by its chemical name only, without additional specifications or HS‑code data in the source information. The supplier is recorded as an imported tier with a harbor trust rating, indicating it operates through international trade channels.

The catalogue focuses on specialty organic intermediates used in dye‑intermediate synthesis, hair‑color formulations and analytical reagents. All six chemicals are supplied in sulfate or dihydrochloride salt forms, which are common for improving water solubility in laboratory applications. No explicit purity grades, packaging sizes or regulatory certifications are provided in the source facts. The product set reflects a niche segment of aromatic amine chemistry that serves both industrial and research markets.

Product Range and Specialties of Yixing Xinyu Chemicals Co., Ltd.

The product list comprises aromatic diamine sulfates and related hydroxy‑ethyl derivatives, which are typical intermediates for azo‑dye production, polymer stabilization and cosmetic formulation. In the broader market, such chemicals are offered in purity grades ranging from 95 % to technical grade 99 %, with analytical certificates specifying water content, heavy‑metal limits and melt point. Buyers often encounter variants with alternative counter‑ions (e.g., chloride, nitrate) and may request bulk quantities packed in HDPE drums or IBC totes.

Industry standards for these categories include compliance with REACH registration in the EU, FDA‑acceptable purity for cosmetic use, and ISO 9001‑based quality management for bulk chemical suppliers. Typical specifications cite a minimum of 98 % assay by HPLC, moisture below 0.5 % and absence of known carcinogenic impurities such as 4‑aminobiphenyl.

Trade and Export Information - Yixing Xinyu Chemicals Co., Ltd.

China remains one of the world’s largest exporters of laboratory and specialty chemicals, with HS Chapter 29 covering organic intermediates like the sulfonated amines listed. Export shipments from Chinese chemical hubs are frequently destined for North America, the European Union and Southeast Asian manufacturing centers, where these intermediates support dye‑manufacturing, personal‑care product formulation and analytical chemistry labs.

International buyers usually require pre‑shipment documentation that includes a Material Safety Data Sheet (MSDS), a Certificate of Analysis (COA) and, where applicable, proof of REACH registration or FDA compliance. Shipping is commonly arranged under CIF or FOB terms, using 20‑ft or 40‑ft containers with inner packaging of sealed drums or bulk bags, and the goods are subject to customs inspections that verify HS code declaration (generally 2922‑99 for aromatic amine salts).

Sourcing from Yixing Xinyu Chemicals Co., Ltd. - Buyer Guidance

When evaluating Yixing Xinyu Chemicals Co., Ltd., buyers should request the latest COA for each listed product, confirming assay, impurity profile and moisture content. An up‑to‑date MSDS is essential for handling sulfonated aromatic amines, which can be hazardous on skin contact and may require specific storage conditions.

Buyers are advised to verify that the supplier can provide REACH registration numbers or FDA compliance statements if the chemicals are intended for cosmetic use. Sampling policies for specialty chemicals often involve a minimum order of 1 kg per product, and lead times from a Chinese manufacturer typically range from 15 to 30 days after order confirmation, depending on production scheduling and customs clearance.
