About Shijiazhuang Kunmai Chemical Technology Co., Ltd. - Chemicals & Allied Products Supplier in China

Shijiazhuang Kunmai Chemical Technology Co., Ltd. operates out of Shijiazhuang in China and lists 90 active chemical products. The catalogue spans inorganic salts such as Caustic Soda (HS 2815.11) and Zinc Ingot (HS 7901.11), organic surfactants like Cocamidopropyl Betaine (HS 3402.19), phosphates including Sodium Tripolyphosphate (HS 2835.31) and Trisodium Phosphate (HS 2835.29), as well as specialty pigments such as Lithopone (HS 3206.49) and Iron‑oxide related compounds. Each entry provides the HS code and the primary chemical composition, for example Stearic Acid Beads (HS 3823.11, C18H36O2) and Sodium Hypochlorite solution (HS 2828.90). The product set reflects the broader categories reported for the supplier: Chemicals & Allied Products, Titanium Dioxide, Agriculture, Iron Oxide, Zinc Oxide, Caustic Soda, Zinc Ingots and Petroleum By‑Products.

The listed chemicals are typical bulk industrial inputs used in water treatment, detergents, metal finishing, and pigment manufacturing. The presence of both inorganic acids (e.g., Oxalic Acid HS 2917.11) and organic polymers (Polyacrylamide HS 3906.90) indicates capability to serve diverse process sectors. While the facts do not disclose certifications, the breadth of HS codes across chapters 28, 29, 32, 38 and 39 shows a wide regulatory scope that buyers must address in their own due‑diligence.

Product Range and Specialties of Shijiazhuang Kunmai Chemical Technology Co., Ltd.

The catalogue includes 30 explicitly detailed products, ranging from basic alkalis such as Caustic Soda (NaOH, 99 % purity typical) to high‑purity electrolytic Zinc Ingots (Zn ≥ 99.99 %). Typical industry grades for Sodium Tripolyphosphate are food‑grade (≥ 98 % P₂O₅) or technical grade (≥ 95 %); the supplier’s entry notes the generic industrial grade. Surfactants like Sodium Dodecyl Sulfate (HS 3402.11) are normally supplied as 30 % w/w aqueous solutions with a cloud point around 20 °C, while Cocamidopropyl Betaine is offered in 10‑30 % solutions for personal‑care formulations. Phosphates, pyrophosphates and trisodium phosphate are commonly shipped as granular or powdered bulk, meeting ISO 9001‑based particle‑size specifications (e.g., D50 ≈ 200 µm). Pigment precursors such as Lithopone (BaSO₄ + ZnS) are supplied as fine powders with typical particle sizes of 1‑5 µm for coating applications.

Industry standards for these chemicals often reference REACH registration for the EU, ASTM D1193 for water‑soluble reagents, and USP <467> for purity of pharmaceutical‑grade acids. Buyers of zinc compounds usually request certification of the 99.99 % minimum purity and an analysis of trace metals (e.g., Pb < 10 ppm). For organic acids like Citric Acid Monohydrate (HS 2918.14) the common specification is ≥ 99.5 % purity with moisture ≤ 0.5 %. The supplier’s product list therefore aligns with typical grade expectations across the chemical spectrum.

Trade and Export Information - Shijiazhuang Kunmai Chemical Technology Co., Ltd.

China remains one of the world’s largest exporters of bulk inorganic chemicals, with major destinations in Southeast Asia, the European Union, and North America. HS chapter 28 (inorganic chemicals) and chapter 32 (dyes and pigments) dominate the customs data for products such as Caustic Soda, Zinc Oxide and Lithopone, while chapter 38 (organic chemicals) covers surfactants and acids. Export shipments are frequently packed in 20‑ft or 40‑ft containers using IBC drums for liquids (e.g., Sodium Hypochlorite) and bulk polypropylene bags for powders (e.g., Sodium Acetate Trihydrate). Common Incoterms are FOB Shijiazhuang or CIF major ports such as Shanghai and Tianjin. Buyers typically require a Material Safety Data Sheet (MSDS), a Certificate of Analysis (CoA) and, for EU markets, proof of REACH registration. Chinese chemical exporters also often provide a Declaration of Conformity to ISO 9001 or ISO 14001, though the supplier’s specific certifications are not listed in the supplied facts.

Regulatory inspection for these categories includes customs sampling under the China Inspection and Quarantine (CIQ) system and possible pre‑shipment testing by third‑party labs. For pigments and oxides, buyers may request compliance with ISO 2243 (pigment purity) and for phosphates, compliance with ISO 9001‑based quality management is standard. The bulk nature of the products means that freight rates are calculated per metric ton, with typical loading capacities of 22 t per 40‑ft container for dense solids like zinc ingot.

Sourcing from Shijiazhuang Kunmai Chemical Technology Co., Ltd. - Buyer Guidance

When sourcing from this supplier, request a recent CoA for each chemical to confirm purity, moisture content and impurity limits (e.g., Zn ≥ 99.99 % for ingots, NaOH ≥ 98 % for caustic soda). An up‑to‑date MSDS is essential for handling and transport, especially for hazardous liquids such as Sodium Hypochlorite and Naphthenic Acid. Verify that the supplier can provide REACH registration numbers or equivalent compliance documents if the goods are destined for the EU market.

Ask for a sample batch of representative product (e.g., 5 kg of Stearic Acid Beads) to run particle‑size analysis and melting‑point verification before committing to a full container load. Confirm packaging details - bulk bags for solids, IBC drums for liquids - and ensure that the packaging material complies with food‑grade or pharmaceutical‑grade requirements when needed. Clarify the minimum order quantity, which for most bulk chemicals from Chinese manufacturers ranges from 10 t to 20 t per shipment, and request a lead‑time estimate that typically spans 30‑45 days from order confirmation to dispatch.

What HS codes are associated with the chemicals offered by Shijiazhuang Kunmai?

The supplier lists products under HS codes such as 2815.11 for Caustic Soda, 7901.11 for Zinc Ingots, 3823.11 for Stearic Acid Beads, 2835.31 for Sodium Tripolyphosphate, 3206.49 for Lithopone and 3402.19 for Cocamidopropyl Betaine, among others.

Which purity levels are typical for the zinc ingot product?

Zinc Ingots are described as electrolytic zinc with a minimum purity of 99.99 % Zn. Buyers usually request a CoA confirming this purity and reporting trace‑metal limits such as Pb < 10 ppm.

Can the supplier provide documentation for REACH or other EU regulations?

The facts do not state any specific certifications, so buyers should explicitly request REACH registration numbers or an EU‑compliance statement as part of the pre‑order documentation.

What packaging formats are used for liquid chemicals like Sodium Hypochlorite?

Liquid chemicals are typically shipped in IBC drums (≈ 200 L) or 55 gal steel drums, sealed according to UN 3373 for hazardous liquids and packed on pallets within a 40‑ft container.

What are the common minimum order quantities (MOQ) for bulk chemicals from this supplier?

While the supplier’s catalogue does not list exact MOQs, Chinese bulk chemical exporters generally set MOQs between 10 tonnes and 20 tonnes per product, depending on the chemical’s handling requirements.

How long does it take to receive a shipment after order confirmation?

Lead times for most listed chemicals range from 30 to 45 days, covering production scheduling, quality testing, packaging and export clearance from Chinese ports.

What quality tests should a buyer request for surfactants like Sodium Dodecyl Sulfate?

Buyers should ask for a CoA that includes active‑ingredient purity (≥ 95 %), cloud‑point measurement, pH of a 1 % aqueous solution, and a microbial limit test if the product is intended for personal‑care use.

Are bulk powders such as Lithopone shipped in bags or drums?

Lithopone, being a fine pigment powder, is normally packed in multi‑layer polypropylene bulk bags (25 kg each) or in sealed steel drums for larger volumes, with moisture‑proof liners to preserve particle integrity.
