Suzhou MHW Chemical. Co., Ltd

Suzhou MHW Chemical. Co., Ltd operates in China and lists 23 active products focused on hyaluronic acid derivatives. The catalogue includes items such as Hyaluronic Acid Cosmetic Grade (HS 3304.99), Food Grade Hyaluronic Acid (HS 3913.90), Sodium Hyaluronate with HS 2936.90, and several entries under HS 2932.99 and HS 2936.29, covering both cosmetic and food applications.

The supplier classifies its offerings under Chemicals & Allied Products, Herbal Extracts, Food Chemicals, and Cosmetics & Beauty Products. Products are described as sodium hyaluronate (C14H21NO11)n, bio‑fermented natural polymer, or microbial fermentation grade, indicating sources ranging from microbial processes to rooster comb extraction. Each entry specifies the material composition and, where provided, the corresponding HS code, allowing buyers to match import classifications accurately.

The listed catalogue consists of various grades of hyaluronic acid and sodium hyaluronate, including cosmetic‑grade powders, food‑grade polymers, and high‑purity forms identified by HS codes 3304.99, 3913.90, 2932.99, 2936.90 and 2936.29. In the broader market, cosmetic‑grade HA typically meets purity levels of 95‑99 % and molecular weights between 0.5 MDa and 2 MDa, while food‑grade HA must comply with food‑contact regulations and often carries a GRAS status in major markets.

Industry standards for these polymers frequently reference ISO 9001 quality management, GMP manufacturing, and, for cosmetics, compliance with the EU Cosmetic Regulation (EC) No 1223/2009. Buyers also look for certificates of analysis confirming moisture content below 5 %, heavy‑metal limits under 10 ppm, and microbial counts within pharmacopeial limits.
