About Hangzhou Chiyang Chemicals Co., Ltd. - Chemicals & Allied Products Supplier in China

China‑based Hangzhou Chiyang Chemicals Co., Ltd. lists five active products in its catalogue. The portfolio includes zinc oxide, chromium oxide green, titanium dioxide, calcium hypochlorite (HS 2828.10) and antimony (HS 8110.10). Each item is presented under the broader Chemicals & Allied Products category, with the two chemically‑defined products carrying explicit HS codes and material descriptors. The zinc oxide and titanium dioxide are identified by their commercial codes (CY008 and CY017) while the pigment‑grade chromium oxide green appears as CY015. The catalogue does not provide further quantitative specifications, but the HS‑code references indicate standard inorganic chemical classifications used in global trade.

Product Range and Specialties of Hangzhou Chiyang Chemicals Co., Ltd.

The listed products cover common inorganic pigments and industrial chemicals. Zinc oxide is typically supplied in grades ranging from 99 % purity to specialty nano‑particle grades used in rubber and cosmetics, while chromium oxide green is a pigment often marketed under CI Pigment Green 17 with particle sizes between 5‑20 µm. Titanium dioxide is usually offered as rutile or anatase grades meeting ISO 13061 or ASTM D525 specifications, with pigment grades above 98 % TiO₂ content. Calcium hypochlorite, classified under HS 2828.10, is commonly shipped as a 65‑70 % available‑chlorine granular product for water treatment. Antimony (HS 8110.10) is supplied as a metalloid with purity between 99.65 % and 99.9 % for flame‑retardant and alloy applications.

Trade and Export Information - Hangzhou Chiyang Chemicals Co., Ltd.

Chinese exporters of inorganic pigments and bleaching agents typically serve paint, plastics, ceramics and water‑treatment industries in Southeast Asia, Europe and North America. HS 2828.10 products such as calcium hypochlorite are regulated under the UN Globally Harmonized System for hazardous chemicals and often require a Material Safety Data Sheet (MSDS) and compliance with local chlorine‑handling regulations. HS 8110.10 antimony shipments are subject to metal‑specific customs controls and may need REACH registration for EU destinations. Buyers usually request certifications such as ISO 9001 quality management, ISO 14001 environmental management, and product‑specific standards like ASTM D574 for zinc oxide purity. Shipping is commonly performed in 20‑ft or 40‑ft containers, with calcium hypochlorite packed in moisture‑resistant bulk bags and the solid pigments in fiber drums or intermediate bulk containers, using FOB or CIF Incoterms.

Sourcing from Hangzhou Chiyang Chemicals Co., Ltd. - Buyer Guidance

When evaluating Hangzhou Chiyang Chemicals, request a current Certificate of Analysis for each product to verify purity, particle‑size distribution and available‑chlorine content where applicable. Verify the presence of an up‑to‑date MSDS and, for EU shipments, a REACH registration dossier for pigments and antimony. Ask for sample quantities - typically 5 kg for powders or 10 L for liquid forms - to run independent laboratory tests before confirming larger orders. Confirm the supplier’s packaging specifications (e.g., 25 kg polypropylene bags for calcium hypochlorite, 20 kg drums for pigments) and inquire about minimum order quantities, which commonly range from 1 ton for bulk chemicals to 500 kg for specialty pigments.

What inorganic pigments does Hangzhou Chiyang Chemicals supply?

The catalogue lists zinc oxide, chromium oxide green and titanium dioxide, each identified by a product code (CY008, CY015, CY017) and commonly used in paints, coatings and plastics.

Which chemical is listed with an HS code of 2828.10?

Calcium hypochlorite is the only product paired with HS 2828.10, indicating it belongs to the inorganic hypochlorite class used for water disinfection.

What purity level is offered for the antimony product?

Antimony is described as 99.65 % - 99.9 % pure metalloid, a typical specification for flame‑retardant and alloy applications.

What documentation should a buyer request for titanium dioxide?

Buyers should request an ISO 13061 or ASTM D525 compliance certificate, a Certificate of Analysis, and an MSDS to confirm grade and safety handling.

Are bulk bags used for any of the listed chemicals?

Calcium hypochlorite is commonly shipped in bulk bags that protect against moisture, which aligns with standard industry practice for this hygroscopic material.

Which Incoterms are typical for shipments from China for these products?

Exporters from China often use FOB (Free on Board) or CIF (Cost, Insurance, Freight) terms, allowing buyers to arrange freight or receive a door‑to‑door service respectively.

What standard certifications are typically required for Chinese pigment exporters?

International buyers usually require ISO 9001 quality management, REACH registration for EU markets, and product‑specific standards such as ASTM for zinc oxide and titanium dioxide.

What sample size is practical for testing calcium hypochlorite?

A 5 kg sample in a sealed, moisture‑proof bag provides enough material for chlorine‑availability testing and compliance verification before a full order.
