About Gansu Qiyuan Chromate Chemical Production Co., Ltd. - Chemicals Supplier in China

Gansu Qiyuan Chromate Chemical Production Co., Ltd. operates in Gansu province, China and lists sixteen distinct chemical products across the categories Chemicals & Allied Products, Industrial Chemicals and Iron Oxide. The catalogue includes sodium dichloroisocyanurate (HS 2933.69) with 56‑62 % active chlorine, ammonium chloride (HS 2827.10) at 99 % purity, calcium bromide (HS 2827.51) industrial grade, as well as a range of oxides, pigments and inorganic acids such as chrome oxide, chromic acid and potassium bichromate. Several entries such as iron oxide, pigment and benzoic acid are listed without specific HS codes, indicating they fall under broader HS chapter 28 or 29 groups. The supplier is classified in the “harbor” trust tier, which reflects a moderate level of verification in the platform ecosystem. All listed items are presented as bulk chemicals suitable for industrial processing and downstream formulation.

The product set spans both organic and inorganic chemicals, covering disinfectants, halide salts, oxide pigments and acid intermediates. Sodium dichloroisocyanurate is commonly used as a chlorine source in water treatment, while ammonium chloride serves as a flux in metalworking and a nitrogen source in fertilizers. Calcium bromide finds application in drilling fluids and photographic chemicals, and iron oxide pigments are widely used in coatings and plastics. The presence of chromate compounds such as potassium bichromate and chromic acid signals capability in corrosion‑inhibiting and plating industries. Each item is identified by its HS code where available, enabling customs classification for international shipments.

Product Range and Specialties of Gansu Qiyuan Chromate Chemical Production Co., Ltd.

The catalogue’s core items are grouped by chemical function: disinfectant agents (sodium dichloroisocyanurate), halide salts (ammonium chloride, calcium bromide, potassium chloride), oxide pigments (iron oxide, chrome oxide, chrome oxide green), and inorganic acids or intermediates (chromic acid, sodium dichromate, phosphorous acid). In the global market, sodium dichloroisocyanurate is typically supplied at 56‑62 % active chlorine and conforms to standards such as ISO 7399‑1 for disinfectant efficacy. Ammonium chloride is offered in 99 % industrial grade, meeting USP or FCC specifications for purity and moisture content. Calcium bromide is usually shipped as anhydrous crystals with ≤0.5 % water, complying with ASTM C889. Iron oxide pigments are graded by colour strength (e.g., IS R‑100) and particle size (often 1‑5 µm for fine grades). Chrome oxide pigments are classified by hue (green, orange) and purity (>99 %).

Trade and Export Information - Gansu Qiyuan Chromate Chemical Production Co., Ltd.

China remains a leading exporter of inorganic chemicals and pigments, with shipments frequently directed to Southeast Asia, the European Union and North America. HS chapter 28 (inorganic chemicals) and chapter 29 (organic chemicals) cover the majority of the listed products; for example, HS 2827 covers ammonium and calcium halides, while HS 2933 includes sodium dichloroisocyanurate. Buyers typically request compliance with REACH registration for EU imports and may require an ISO 9001 quality management certificate, although the supplier’s own certifications are not disclosed in the provided data. Standard export packaging includes 20 ft or 40 ft containers with inner drums (55 gal) or bulk bags (1 ton) for solid salts, and IBC totes for liquid acids. Incoterms such as FOB or CIF are commonly negotiated, and customs clearance often involves submission of a material safety data sheet (MSDS) and a certificate of analysis (CoA).

Sourcing from Gansu Qiyuan Chromate Chemical Production Co., Ltd. - Buyer Guidance

When sourcing from Gansu Qiyuan Chromate, buyers should request a current MSDS for each chemical, a CoA that specifies purity, moisture and heavy‑metal limits, and confirmation of REACH registration if the destination is the EU. For pigment products, buyers normally verify particle size distribution, colour index (CI) number and tinting strength through a third‑party lab report. Because no certifications are listed, it is prudent to ask for ISO 9001 or ISO 14001 copies, as well as any export‑specific licences required for chromate compounds, which are subject to environmental controls. Sampling is typically offered in 1 kg bags for salts and 500 g jars for pigments, allowing verification of solubility, colour consistency and any required pH specifications before confirming larger orders.

Typical lead times for bulk chemicals from Chinese manufacturers range from 20 to 45 days after receipt of a pro‑forma invoice, depending on production scheduling and customs clearance. Minimum order quantities (MOQ) vary by product: salts such as ammonium chloride are often sold in 25 ton parcels, while specialty pigments may have an MOQ of 500 kg. Buyers should also confirm container loading plans to ensure compliance with hazardous material regulations for chromate and acid products.

What HS codes are associated with the chemicals listed by Gansu Qiyuan Chromate?

The supplier provides HS 2933.69 for sodium dichloroisocyanurate, HS 2827.10 for ammonium chloride and HS 2827.51 for calcium bromide. Other items fall under broader HS chapter 28 (inorganic chemicals) or chapter 29 (organic chemicals) without a specific code in the catalogue.

Which purity grades are offered for ammonium chloride?

Ammonium chloride is listed as 99 % industrial/pharma grade, which aligns with USP‑NF or FCC specifications for impurity limits and moisture content.

Are chromate compounds subject to special export documentation?

Yes, chromic acid, potassium bichromate and related chromate products are classified as hazardous under international regulations. Exporters must provide a hazardous materials declaration, MSDS and any required environmental permits.

What typical packaging formats are used for the bulk salts?

Bulk salts such as sodium dichloroisocyanurate, ammonium chloride and calcium bromide are commonly packed in 20 ft or 40 ft containers with 55 gal steel drums or 1‑ton bulk bags, sealed to prevent moisture ingress.

Which quality certifications should a buyer request for these chemicals?

Buyers should ask for ISO 9001 or ISO 14001 certificates, a current REACH registration for EU shipments, and a certificate of analysis that details purity, moisture and heavy‑metal content.

What are the standard lead times and MOQ for pigment products?

Pigment orders such as iron oxide or chrome oxide green typically have a minimum order of 500 kg and a lead time of 30‑45 days from order confirmation, depending on production scheduling.

How can a buyer obtain a sample before placing a full order?

The supplier can provide 500 g to 1 kg sample packs of pigments and 1 kg sample bags of salts, shipped by air or express courier, accompanied by an MSDS and a provisional CoA.

What are the common end‑use industries for the listed chemicals?

Sodium dichloroisocyanurate is used in water treatment and disinfection, ammonium chloride in metalworking and fertilizer blends, calcium bromide in drilling fluids, iron oxide pigments in coatings, plastics and inks, and chromate compounds in metal plating and corrosion‑inhibition systems.
