About Yat Sun Dyestuffs & Chemicals Co., Ltd. - Textile Chemicals Supplier in Hong Kong

Hong Kong‑based Yat Sun Dyestuffs & Chemicals Co., Ltd. lists five distinct textile‑chemical products in its current catalogue. The supplier is classified as an imported tier with a harbor trust rating, indicating that it operates through Hong Kong’s major trading ports. The catalogue includes Lutexal thickener hit, Decrolin (zinc formaldehyde sulfoxylate), Helizarin binder tow, Sodium Formate and Formic Acid. All items fall under the broad textile chemicals category, which is typically recorded under HS Chapter 38 for chemical products used in textile processing. These chemicals are commonly employed in dye‑fixation, fabric finishing, and pH‑adjustment steps in textile manufacturing.

Product Range and Specialties of Yat Sun Dyestuffs & Chemicals Co., Ltd.

The listed products cover three functional groups: a thickener (Lutexal), a zinc‑based reducing agent (Decrolin), a binder (Helizarin), and two low‑molecular‑weight acids (Sodium Formate and Formic Acid). In the textile chemicals market, thickeners are graded by viscosity (e.g., 30 mPa·s at 25 °C) and shear stability, while zinc formaldehyde sulfoxylate is specified by zinc content (typically 30‑35 % Zn) and reducing power (measured in mEq). Binders such as Helizarin are evaluated for polymer adhesion strength and moisture resistance. Sodium Formate and Formic Acid are usually supplied with purity levels of 98 % - 99 % and moisture content below 0.5 %.

Trade and Export Information - Yat Sun Dyestuffs & Chemicals Co., Ltd.

Hong Kong serves as a major transshipment hub for textile chemicals destined for East‑Asian, European and North‑American garment producers. Exporters from Hong Kong often ship under HS 3808 (preparations for textile use) and HS 3815 (formic acid) with standard container sizes - a 20 ft container can hold roughly 15 tons of powdered chemicals or 20 tons of liquid acids. Buyers typically request compliance with REACH registration, ISO 9001 quality management and, where applicable, Oeko‑Tex Standard 100 for downstream textile safety. Packaging follows UN Globally Harmonized System (GHS) labeling, with bulk shipments in sealed IBCs for liquids and multi‑layer polyethylene bags for powders. Common Incoterms include FOB Hong Kong or CIF destination port, allowing buyers to manage customs duties in the importing country.

Sourcing from Yat Sun Dyestuffs & Chemicals Co., Ltd. - Buyer Guidance

When sourcing from Yat Sun, buyers should obtain a current Safety Data Sheet (SDS) for each chemical, a recent analytical certificate confirming purity and moisture content, and evidence of REACH registration where required. For the thickener and binder, a viscosity or adhesion test report helps verify performance against formulation specifications. Requesting a small trial sample (e.g., 2 kg of powder or 10 L of acid) before full‑scale order is standard practice to assess compatibility with existing textile processes. Verify that the supplier can provide batch‑level certificates of analysis (CoA) and that shipping containers are sealed and labeled according to GHS requirements.
