About Zhengzhou Sino Chemical Co., Ltd - Industrial Chemicals Supplier in China

Zhengzhou Sino Chemical Co., Ltd is based in Zhengzhou, China and lists five active products across industrial chemicals, caustic soda, iron oxide pigments and water‑treatment chemicals. The catalogue includes Calcium Hypochlorite 70 % (HS 2828.10, Ca(OCl)2 70 %), Industrial‑grade NaOH Flakes (HS 2815.11, Sodium Hydroxide), a yellow iron oxide pigment, a red iron oxide pigment and a TCCA swimming‑pool powder. Each entry is identified by its material composition and, where provided, the relevant HS‑code for customs classification. The supplier’s product set reflects common Chinese export lines in bulk chemicals and inorganic pigments.

The product set focuses on bulk chemicals used in disinfection, water treatment and pigment manufacturing. Calcium hypochlorite is supplied at a technical grade of 70 % available chlorine, while caustic soda flakes are offered as industrial‑grade sodium hydroxide. The iron oxide pigments are described by colour only, typical of Fe2O3 pigments used in coatings, and the TCCA powder is positioned for swimming‑pool sanitation. No additional certifications are listed in the supplied data.

Product Range and Specialties of Zhengzhou Sino Chemical Co., Ltd

The catalogue covers five distinct items: a 70 % calcium hypochlorite solid, industrial‑grade sodium hydroxide flakes, yellow and red iron‑oxide pigments and a TCCA (trichloroisocyanuric acid) powder for pool water treatment. In the chemical trade, calcium hypochlorite is normally shipped in 25 kg or 50 kg bags with moisture content below 5 %, and buyers often request a chlorine‑active content test (ISO 7390‑2). Sodium hydroxide flakes are typically 99 % pure, packaged in 25 kg bags, and must meet the specifications of ISO 9001 for production and ISO 14001 for environmental management. Iron‑oxide pigments are usually supplied as Fe2O3 with particle sizes ranging from 1 µm to 10 µm, colour strength measured by tinting strength (e.g., 100 % for red, 80 % for yellow) and packaged in 25 kg or 200 kg drums. TCCA pool‑grade powder is commonly 65 % active chlorine, supplied in 25 kg bags, and conforms to ASTM D 7282 for purity and heavy‑metal limits.

Trade and Export Information - Zhengzhou Sino Chemical Co., Ltd

China is a major exporter of bulk inorganic chemicals and pigments, with shipments from coastal ports to markets in Southeast Asia, the Middle East and Africa. HS 2828.10 and HS 2815.11 fall under Chapter 28, which is subject to standard customs documentation, a certificate of origin and, where required, a REACH registration for EU destinations. Typical export containers are 20‑ft or 40‑ft dry containers, holding up to 20 tons of calcium hypochlorite or caustic soda, while pigments may be loaded in fewer units due to weight limits. Buyers frequently request ISO 9001 compliance, a Material Safety Data Sheet (MSDS), and a Certificate of Analysis (CoA) for each batch. Common Incoterms used by Chinese chemical exporters include FOB Zhengzhou Port and CIF destination port, with bulk cargo secured in wooden pallets or steel drums depending on the material.

Sourcing from Zhengzhou Sino Chemical Co., Ltd - Buyer Guidance

When sourcing from Zhengzhou Sino Chemical, request the latest MSDS and CoA for each product to verify active chlorine content, sodium hydroxide purity and pigment tinting strength. Verify that the supplier can provide REACH registration numbers if the shipment is intended for the EU, and ask for any ISO certifications that apply to the production line. Confirm packaging specifications - 25 kg bags for calcium hypochlorite and NaOH, 200 kg drums for pigments - and ensure that the container loading plan matches your logistics capacity. Typical minimum order quantities are one 20‑ft container for bulk chemicals, with lead times of 30‑45 days from order confirmation.

What grades of calcium hypochlorite does Zhengzhou Sino Chemical offer?

The catalogue lists Calcium Hypochlorite at 70 % active chlorine, which matches the technical grade commonly used for water treatment and disinfection. Buyers usually verify the chlorine content against ISO 7390‑2 and request a CoA for each batch.

Are the NaOH flakes suitable for industrial cleaning applications?

The NaOH flakes are described as industrial‑grade sodium hydroxide, typically 99 % purity. They are packaged in 25 kg bags and meet the standard specifications referenced in ISO 9001 for chemical production.

What specifications apply to the yellow and red iron‑oxide pigments?

The pigments are iron‑oxide (Fe2O3) powders identified by colour; standard industry specifications include particle size distribution (1‑10 µm) and tinting strength (approximately 80 % for yellow, 100 % for red). Buyers often request a CoA that includes these parameters and heavy‑metal limits per ASTM D 7282.

Is the TCCA powder compliant with pool‑water safety standards?

The TCCA (trichloroisocyanuric acid) powder is marketed for swimming‑pool treatment and typically contains 65 % active chlorine. Compliance with ASTM D 7282 for purity and heavy‑metal content is a common requirement for pool‑grade chemicals.

Which HS codes are used for customs clearance of these products?

Calcium Hypochlorite 70 % uses HS 2828.10, and Sodium Hydroxide flakes use HS 2815.11. The pigments and TCCA powder are not assigned HS codes in the supplied data, so buyers should confirm the appropriate sub‑headings with the supplier before shipment.

What documentation should I request before placing an order?

Request a current MSDS, a Certificate of Analysis for each product batch, any ISO certifications related to production, and REACH registration evidence if exporting to the European Union. These documents help verify purity, safety and regulatory compliance.

What are the typical container sizes and lead times for orders?

Bulk chemicals such as calcium hypochlorite and caustic soda are usually loaded in 20‑ft or 40‑ft dry containers, with a standard lead time of 30‑45 days from order confirmation. Pigments and TCCA powder may be shipped in fewer containers due to weight constraints, but the same lead‑time range generally applies.

How is the product packaged for international shipping?

Calcium hypochlorite and NaOH flakes are packed in 25 kg woven polypropylene bags, often placed on wooden pallets. Iron‑oxide pigments are typically shipped in 200 kg steel drums, and TCCA powder is also packed in 25 kg bags, all sealed to prevent moisture ingress.
