About Huaqiang Chemical Group Stock Co., Ltd. - Chemicals & Allied Products Supplier in China

China hosts Huaqiang Chemical Group Stock Co., Ltd., which lists 15 active products in its public catalogue. The catalogue covers chemicals and allied products, with a focus on fertilizers and industrial chemicals. It includes five NPK fertilizer formulations such as 15‑15‑15, 17‑17‑17 and 20‑20‑20, plus water‑soluble 20‑20‑20, as well as potassium sulfate (HS 3104.30) and chlorinated humic acid (HS 3824.99). High‑purity industrial chemicals are also listed: melamine powder (2933.61, 99.8 % purity), hydrogen peroxide (50 %/27.5 %), ammonium bicarbonate, sodium nitrite (99.9 %) and sodium nitrate (99.9 %).

The NPK fertilizers fall under HS chapter 31 for organic fertilizers and are usually supplied in 25 kg bags or bulk containers. Melamine powder is classified under HS chapter 29 for organic chemicals and is typically shipped in 20‑ft containers with moisture below 0.2 %. Potassium sulfate belongs to HS 3104.30 and is commonly exported in 50 kg bags. Overall the product list spans HS 29, 31 and 38 code families, covering both agricultural and industrial chemical markets.

Product Range and Specialties of Huaqiang Chemical Group Stock Co., Ltd.

The listed fertilizer line includes balanced NPK blends (15‑15‑15, 17‑17‑17, 20‑20‑20) and a water‑soluble 20‑20‑20 formulation. In the industry these grades are specified with a nutrient tolerance of ±5 % and granule sizes of 2‑4 mm, moisture content typically under 10 %. Potassium sulfate is offered as a USP‑grade salt with ≥99 % K₂SO₄ purity and solubility around 120 g L⁻¹ at 20 °C. Melamine powder at 99.8 % purity is standard for resin production; buyers normally check moisture <0.3 % and heavy‑metal limits <10 ppm. Hydrogen peroxide 50 % solution is used for bleaching and oxidation, with stability periods of six months and a typical concentration verification by titration. Ammonium bicarbonate, sodium nitrite and sodium nitrate are supplied in industrial grades where purity is ≥99 % and moisture is below 2 %.

Trade and Export Information - Huaqiang Chemical Group Stock Co., Ltd.

China is a major exporter of both agricultural and industrial chemicals. Fertilizer blends such as the NPK series are most frequently shipped to South‑East Asian, African and Latin American farms, often under HS 3105 (fertilizers) with CIF or FOB terms. Melamine, potassium sulfate, sodium nitrite and sodium nitrate fall under HS 29 and HS 31 categories and are commonly required by buyers in the plastics, glass and food‑preservation sectors; typical certifications include ISO 9001 quality management, SGS inspection reports and compliance with Chinese GB standards and EU REACH where applicable. Chlorinated humic acid (HS 3824.99) is a niche soil amendment exported mainly to specialty agronomy markets. Standard packaging includes 25 kg polypropylene bags for fertilizers, 20‑ft containers for bulk powders, and 200 L IBCs for liquid hydrogen peroxide. Export documentation usually comprises a commercial invoice, packing list, certificate of origin, safety data sheet and any required import permits for chemicals.

Sourcing from Huaqiang Chemical Group Stock Co., Ltd. - Buyer Guidance

Buyers should request a detailed product specification sheet that lists nutrient analysis (N, P₂O₅, K₂O) for each NPK blend, moisture content, granule size distribution and any heavy‑metal limits. For melamine and the inorganic salts, a third‑party purity certificate, moisture test result and heavy‑metal analysis (e.g., lead, arsenic) are standard verification documents. Hydrogen peroxide shipments must be accompanied by a concentration certificate, safety data sheet and a stability test report. Confirm that the HS code on the commercial invoice matches the product category and request packaging details (bag weight, inner liner material, container seal). Typical minimum order quantities are 1 ton for bulk chemicals and 10 tons for fertilizer blends, with a standard lead time of 30‑45 days after order confirmation, subject to regulatory clearance.

What NPK fertilizer ratios does Huaqiang Chemical Group Stock Co., Ltd. offer?

The catalogue lists balanced blends of 15‑15‑15, 17‑17‑17 and 20‑20‑20, plus a water‑soluble 20‑20‑20 formulation. All ratios are expressed on a nutrient (N‑P‑K) basis and are supplied in standard 25 kg bags.

How is the purity of the 99.8 % melamine powder verified?

Purity is normally confirmed by an independent laboratory using high‑performance liquid chromatography (HPLC) or gas chromatography, with results documented on a third‑party certificate. Buyers should also request moisture content (<0.3 %) and heavy‑metal limits as part of the test report.

Which HS codes apply to the products listed by the supplier?

Melamine powder uses HS 2933.61, potassium sulfate HS 3104.30, chlorinated humic acid HS 3824.99, and the NPK fertilizers fall under HS 3105 (fertilizers). Hydrogen peroxide, ammonium bicarbonate, sodium nitrite and sodium nitrate are classified under their respective HS chapters for inorganic chemicals.

What packaging formats are used for the fertilizer products?

Fertilizer blends are typically packed in 25 kg polypropylene bags with an inner liner for moisture protection. Bulk shipments may also be loaded into 20‑ft or 40‑ft containers for larger orders.

Are safety data sheets (SDS) provided for hazardous chemicals such as hydrogen peroxide?

Yes, an SDS covering handling, storage, transport and emergency measures is standard for hydrogen peroxide and other hazardous chemicals. Buyers should request the latest SDS version before shipment.

Which certifications should a buyer request for these chemicals?

Buyers commonly ask for ISO 9001 quality‑management certification, SGS or Intertek inspection reports, and compliance statements with Chinese GB standards or EU REACH, depending on the destination market.
