Chengdu Taiyu Industrial Gases Co., Ltd.

Chengdu Taiyu Industrial Gases Co., Ltd. is based in Chengdu, China and lists 26 active industrial gas products. The catalogue spans the Chemicals & Allied Products, Industrial Gases, Industrial Chemicals and Batteries & Chargers categories. Products include common bulk gases such as Oxygen, Nitrogen, Hydrogen and Carbon Dioxide, each assigned to HS chapter 28 (e.g., 2804.30 for O2 and N2). Specialty gases such as Xenon, Helium, Argon and rare gases are also offered, listed under HS codes 2804.29. Several halogenated compounds, including Sulfur Hexafluoride (HS 2804.80) and Tungsten Hexafluoride (HS 2811.19), complete the portfolio.

Purity levels indicated in the catalogue range from 99.5 % for industrial methane to 99.999 % for noble gases and fluorinated compounds. The supplier also provides compressed‑gas forms, for example the 8 g N₂O whipped‑cream charger packaged in recyclable carbon steel. Gaseous products are identified by their chemical formula and material description, such as high‑purity Silane SiH₄ (99.99‑99.9999 %). The HS codes cover both gas in bulk (2804 series) and specific chemical compounds (e.g., 2811.29 for Sulfur Dioxide). No additional product information beyond the listed catalogue is supplied.

The listed catalogue contains industrial gases ranging from common atmospheric gases (O₂, N₂, Ar, He) to specialty high‑purity gases (Xe 99.999 %, SF₆ 99.999 %). Halogenated and fluorinated compounds such as Methyl Chloride, Boron Trifluoride, Nitrogen Trifluoride and Tungsten Hexafluoride are supplied with purity specifications between 99.9 % and 99.999 % as noted in the product descriptions. In the industrial gases market, buyers typically reference purity grades (Grade 1 ≥ 99.99 %, Grade 2 ≥ 99.5 %) and demand compliance with ASTM D 3889 for gases, ISO 14625 for cylinder compatibility, and IEC 60529 for packaging protection.

Typical industry practice for these gases includes delivery in high‑pressure steel cylinders (e.g., 50 L or 150 L DIN‑EN 3) for bulk gases and in smaller regulated cartridges for specialty gases. Noble gases are often required at 99.999 % (5 N) or higher for semiconductor and lighting applications, while fluorinated gases used in circuit‑breaker or semiconductor etching processes may require 99.9999 % (6 N) purity. Moisture content is usually limited to < 10 ppm for high‑purity gases, and cylinder cleaning and leak‑testing follow ISO 15528 standards.
