About China Hangzhou Titan Chemical Co., Ltd - Organometallic Chemicals Supplier in China

Hangzhou, China hosts China Hangzhou Titan Chemical Co., Ltd, which currently lists five active products in its catalogue. The product portfolio comprises the organometallic precursors Trimethylindium, Trimethylgallium, Diethyl zinc, the phenolic compound 2‑cyclohexyl‑5‑methyl phenol, and the hydrochloride salt 1‑Amino‑Cyclopropyl Cyanic Hydrochloride. All listed items fall under the HS chapter 29 family for organic chemicals, with the metal‑organic precursors typically classified under sub‑headings for organometallic compounds. The catalogue does not provide HS codes, but the chemicals are standard bulk chemicals used in semiconductor and specialty chemical markets. The supplier is classified as an imported tier with a harbor trust tier, indicating a verified trade track record on the platform. Trimethylindium and Trimethylgallium are commonly employed as metal‑organic sources in metal‑organic chemical vapor deposition (MOCVD) for III‑V compound semiconductors. Diethyl zinc serves as a zinc source in similar epitaxial processes, while 2‑cyclohexyl‑5‑methyl phenol is used as an antioxidant or intermediate in polymer synthesis. 1‑Amino‑Cyclopropyl Cyanic Hydrochloride is a specialty intermediate for agro‑chemical or pharmaceutical routes. The five‑product list reflects a focused portfolio on high‑purity organometallic and specialty organic chemicals.

Product Range and Specialties of China Hangzhou Titan Chemical Co., Ltd

The catalogue’s organometallic chemicals are typically offered in purity grades ranging from 99.99 % to 99.9999 % (commonly denoted as 5N‑6N). Trimethylindium and Trimethylgallium are generally supplied in sealed, nitrogen‑purged stainless‑steel containers or ampoules to prevent oxidation, with moisture content below 10 ppm. Diethyl zinc is similarly packaged under inert atmosphere, often in 25 kg drums or 1 L stainless steel bottles, with specifications for water content under 5 ppm. 2‑Cyclohexyl‑5‑methyl phenol is usually provided as a liquid with a typical acid value below 2 mg KOH/g and a flash point above 150 °C. 1‑Amino‑Cyclopropyl Cyanic Hydrochloride is delivered as a solid powder with particle size distribution in the 50‑200 µm range and a minimum purity of 98 %. Buyers in the semiconductor sector typically request ICP‑OES or GDMS analysis to confirm trace‑metal levels for these precursors.

Trade and Export Information - China Hangzhou Titan Chemical Co., Ltd

Organometallic precursors from China are exported under HS Chapter 29.9 for organometallic compounds, with most shipments using 20‑ft or 40‑ft containers equipped with temperature‑controlled and moisture‑controlled interiors. Typical destination regions include East Asia (South Korea, Taiwan, Japan), North America, and Western Europe, where semiconductor fabs and research labs source these chemicals. Export documentation commonly requires a Material Safety Data Sheet (MSDS), a Certificate of Analysis (CoA), and compliance with REACH registration for the EU market. Importers often request additional certifications such as ISO 9001 quality management or ISO 14001 environmental management, although these are not listed as held by this supplier.

Sourcing from China Hangzhou Titan Chemical Co., Ltd - Buyer Guidance

Prospective buyers should request the latest CoA for each batch, confirming purity, moisture, metal‑contaminant levels and residual solvents. For the metal‑organic precursors, a GDMS or ICP‑MS trace‑metal analysis is standard, and the supplier should provide a stability test report for the intended storage period. Verify that the packaging meets inert‑atmosphere requirements and that the containers are compliant with UN 3172 for hazardous liquids where applicable. Typical minimum order quantities range from 5 kg for Trimethylindium and Trimethylgallium to 10 kg for Diethyl zinc, with lead times of 4‑6 weeks for production and 2‑3 weeks for shipment.

What product categories does China Hangzhou Titan Chemical Co., Ltd offer?

The supplier lists five products: the organometallic precursors Trimethylindium, Trimethylgallium and Diethyl zinc, the phenolic compound 2‑cyclohexyl‑5‑methyl phenol, and the hydrochloride salt 1‑Amino‑Cyclopropyl Cyanic Hydrochloride. These fall under the HS Chapter 29 family for organic chemicals, with the organometallics classified under sub‑headings for organometallic substances.

Which HS code families apply to these chemicals?

All items are covered by HS Chapter 29 for organic chemicals, and the organometallic compounds are typically recorded under sub‑headings 29.31‑29.34 for organometallic substances. Importers should verify the exact sub‑heading on the commercial invoice to ensure correct tariff treatment.

What purity levels are typical for the metal‑organic precursors?

Industry buyers usually require 5‑N (99.999 %) or higher purity, with moisture content below 10 ppm and residual solvent limits defined by the Certificate of Analysis. Suppliers normally provide GDMS or ICP‑MS data to confirm trace‑metal specifications for each batch.

What documentation should a buyer request before purchasing?

Buyers should obtain a current Certificate of Analysis, an up‑to‑date Material Safety Data Sheet, and, for EU shipments, a REACH registration confirmation. Additional quality‑system certificates such as ISO 9001 are commonly requested to verify the supplier’s quality management.

How are the organometallic chemicals packaged for export?

They are commonly shipped in nitrogen‑purged stainless‑steel containers or sealed ampoules, placed inside moisture‑controlled 20‑ft or 40‑ft containers that comply with UN transport regulations for hazardous liquids. Packaging is usually labeled with the UN number, proper shipping name, and handling instructions.

What are typical lead times and minimum order quantities?

Lead times are generally 4‑6 weeks for production plus 2‑3 weeks for freight, depending on the specific precursor and destination. Minimum order quantities range from 5 kg for Trimethylindium and Trimethylgallium to 10 kg for Diethyl zinc, with larger batches often offering economies of scale.
