About Zhejiang Chenxin Technology Co., Ltd. - Chemicals & Allied Products Supplier in China

Zhejiang Chenxin Technology Co., Ltd. is located in Zhejiang province, China and currently lists 28 active chemical products. The catalogue focuses on imidazole‑based heterocyclic compounds, including 1‑methylimidazole, 2‑methylimidazole, 2‑ethylimidazole and related derivatives. Most of these items are classified under HS chapter 29, specifically HS code 2933.29 for heterocyclic organic chemicals, while 2‑bromofluorobenzene is listed under HS code 2903.99 and the pharmaceutical API metronidazole falls under HS code 2933.19. Each entry provides the CAS number and a brief material description, such as purity levels of 99 % or higher for many of the imidazole derivatives.

The supplier’s top categories are listed as Chemicals & Allied Products and Agriculture, indicating that the chemicals may be used as agro‑chemical intermediates as well as in pharmaceutical synthesis. The product set includes both standard reagents (e.g., N,N‑carbonyldiimidazole) and specialty antifungal agents such as climbazole. All listed chemicals are organic heterocyclic compounds with molecular formulas ranging from C4H6N2 to C15H18BrClN2O. No certifications are claimed in the supplied data, and the supplier is identified as an imported tier with a harbor trust rating. The catalogue therefore provides a concise view of Chinese‑origin imidazole chemistry suitable for global buyers.

Product Range and Specialties of Zhejiang Chenxin Technology Co., Ltd.

Zhejiang Chenxin’s catalogue comprises a variety of imidazole derivatives, each typically supplied with a minimum purity of 99 % and accompanied by a material safety data sheet (MSDS). In the broader chemical industry, imidazole reagents are graded by purity (e.g., 98 %, 99 %, 99.5 %) and by moisture content, which is often limited to ≤0.1 % for pharmaceutical‑grade materials. Common specifications also include appearance (white solid or powder) and storage conditions (dry, sealed containers). Buyers of these compounds frequently request certificates of analysis (COA) that detail assay, water content, and residual solvents, as well as compliance with REACH, TSCA, or ISO 9001 quality management systems. The presence of 2‑bromofluorobenzene (HS 2903.99) and metronidazole (HS 2933.19) expands the range into halogenated aromatics and active pharmaceutical ingredients, which are normally subject to stricter batch‑release testing and GMP documentation.

Trade and Export Information - Zhejiang Chenxin Technology Co., Ltd.

Chinese exporters of fine organic chemicals such as imidazoles typically ship to Europe, North America, and Southeast Asia, where these intermediates are used in agro‑chemical formulation and drug synthesis. The HS‑code family 2933 covers heterocyclic organic compounds, and customs authorities often require a full COA, MSDS, and a certificate of origin for each shipment. Commonly requested certifications include REACH registration for the EU market, US TSCA inventory listing, and ISO 9001 quality‑system certification, although the supplier’s own holdings are not documented. Standard packaging for bulk chemicals includes 25 kg IBC totes, 20 kg drums, or smaller 1 kg glass bottles, with labeling that meets GHS hazard communication standards. Typical Incoterms used by Chinese chemical suppliers are FOB Shanghai or CIF destination port, with freight handled by container or bulk tanker depending on volume.

Sourcing from Zhejiang Chenxin Technology Co., Ltd. - Buyer Guidance

When sourcing from Zhejiang Chenxin, buyers should request a current COA for each specific batch, an up‑to‑date MSDS, and any available REACH or TSCA compliance statements. Because purity is a critical parameter for pharmaceutical and agro‑chemical applications, confirming assay values (≥99 %) and moisture limits (≤0.1 %) before order confirmation is advisable. Verify the HS code on the commercial invoice matches the product (e.g., 2933.29 for most imidazoles) and ensure the packaging meets the intended transport mode. Typical minimum order quantities for fine chemicals range from 1 kg to 5 kg, with lead times of 2 - 4 weeks after receipt of a purchase order and payment of a sample fee if required. Requesting a small sample (often 100 g) with a COA can help validate purity and compatibility before scaling up.

What purity levels are offered for the imidazole derivatives?

The catalogue specifies that most imidazole derivatives are supplied with a minimum purity of 99 %, and many are marketed at 99.5 % or higher, which is standard for fine‑chemical intermediates.

Which documentation should I ask for before placing an order?

Request a current Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), and any REACH or TSCA compliance certificates relevant to the destination market.

What HS codes apply to the listed products?

The majority of the imidazole chemicals fall under HS code 2933.29, 2‑bromofluorobenzene uses HS code 2903.99, and the pharmaceutical API metronidazole is classified under HS code 2933.19.

Are there typical certifications that buyers expect from Chinese chemical suppliers?

Buyers commonly expect ISO 9001 quality‑system certification, REACH registration for EU imports, and TSCA compliance for US shipments, although the supplier has not listed specific holdings.

What are the usual packaging options for these chemicals?

Standard packaging includes 25 kg IBC totes, 20 kg steel drums, or smaller 1 kg glass bottles, all sealed to prevent moisture ingress and labeled according to GHS requirements.

What Incoterms are typically used for shipments from this supplier?

Export transactions often use FOB Shanghai or CIF to the buyer’s destination port, allowing the buyer to choose the freight forwarder or have the supplier arrange door‑to‑door delivery.

What is the typical minimum order quantity and lead time?

Minimum order quantities usually start at 1 kg for fine chemicals, with a standard lead time of 2 - 4 weeks after order confirmation and receipt of payment.

Can I obtain a sample before placing a larger order?

Yes, the supplier can provide a sample (commonly 100 g) together with a COA, enabling the buyer to verify purity and suitability before committing to a full‑scale purchase.
