About Weifang Qihui Chemical Co., Ltd. - Calcium Chloride Supplier in China

China‑based Weifang Qihui Chemical Co., Ltd. lists eight active chemical products across calcium chloride, caustic soda and urea categories. The catalogue includes 99 % caustic soda flakes, 99 % caustic soda pearls (HS 2815.11), anhydrous calcium chloride 94 % (HS 2827.32), several 74 % calcium chloride forms - powder, pellets and flakes (HS 2827.31) and a 46 % urea fertilizer. Each entry specifies the material composition and, where provided, the relevant HS‑code family for customs classification. The supplier is classified as an imported tier with a harbor trust tier, indicating participation in standard Chinese export channels.

The product list shows a focus on high‑purity inorganic chemicals used in water treatment, detergent manufacturing and agricultural fertiliser blending. Calcium chloride items are offered in both anhydrous and hydrated forms, while caustic soda appears as both flakes and pearls, reflecting common downstream processing requirements. The urea product is presented as a 46 % nitrogen fertilizer, a typical grade for bulk agricultural use. No additional product variants or certifications are stated in the supplied data.

Product Range and Specialties of Weifang Qihui Chemical Co., Ltd.

The eight listed chemicals cover two primary material families: sodium hydroxide (caustic soda) and calcium chloride, plus a nitrogen‑based fertilizer (urea). In the global market, caustic soda is supplied at 99 % purity in flake or pearl form, with typical specifications including moisture ≤ 1 % and sodium carbonate ≤ 0.5 %. Calcium chloride is commonly graded at 94 % (anhydrous) for industrial drying and at 74 % for bulk de‑icing or dust control, with standard impurity limits for iron, magnesium and silica. Urea fertilizer is usually marketed at 46 % nitrogen (N) content, granule size 2 - 4 mm, and moisture ≤ 1 %. Buyers often request certificates of analysis confirming these parameters, as well as material safety data sheets (MSDS) for handling and transport.

Trade and Export Information - Weifang Qihui Chemical Co., Ltd.

China is a leading exporter of inorganic chemicals, and shipments of calcium chloride, caustic soda and urea frequently target regions such as Southeast Asia, the Middle East, Africa and Latin America where water‑treatment plants, detergent producers and agricultural sectors are expanding. The HS‑code families present in the catalogue - 2815 (sodium hydroxide), 2827 (calcium chloride) and 3102 (urea) - are routinely examined by customs for compliance with import licensing and safety regulations. Typical buyer requirements include ISO 9001 quality management evidence, REACH registration for the European market, and compliance with local hazardous material handling rules. Export logistics from Chinese ports usually involve bulk bagging (25 kg or 1 ton bags) for powders and pellets, and 20‑ft or 40‑ft containers for flakes and pearls, with FOB or CIF terms prevailing in most contracts.

Sourcing from Weifang Qihui Chemical Co., Ltd. - Buyer Guidance

When sourcing from this supplier, buyers should request a current MSDS for each chemical, a certificate of analysis confirming purity (e.g., 99 % NaOH, 94 % CaCl₂), and any relevant REACH or local regulatory documentation. Sampling is standard practice; a 5 kg sample of the 74 % calcium chloride powder can verify particle size distribution and impurity levels before a bulk order. Verify packaging specifications - bulk bags for powders and sealed drums for caustic soda pearls - and ensure that the container weight and volume match the quoted HS‑code tariff classifications. Confirm lead times, minimum order quantities (often 20 metric tonnes for bulk chemicals) and the preferred Incoterm before finalising the purchase.

What forms of calcium chloride does the supplier offer?

The catalogue lists anhydrous calcium chloride at 94 % purity (HS 2827.32) and three 74 % variants - powder, pellets and flakes - all classified under HS 2827.31.

Which caustic soda products are available?

Two forms are listed: 99 % caustic soda flakes (no HS code provided) and 99 % caustic soda pearls, which fall under HS 2815.11.

Is a certificate of analysis provided for the chemicals?

The supplier’s facts do not specify any certificates; buyers should request a current COA for each product to verify purity and impurity limits.

What documentation is typically required for importing urea fertilizer?

Importers usually ask for a certificate of analysis showing 46 % nitrogen content, an MSDS, and any regional agricultural import permits or REACH registration if destined for the EU.

What are the common packaging methods for the listed powders?

Bulk chemicals such as calcium chloride powder and pellets are commonly packed in 25 kg paper bags or 1‑ton woven polypropylene bags, suitable for 20‑ft container loading.

What are typical lead times and minimum order quantities?

For bulk inorganic chemicals from China, lead times range from 30 to 45 days and minimum order quantities are often around 20 metric tonnes, though exact figures should be confirmed with the supplier.

Which HS codes apply to the calcium chloride products?

The 94 % anhydrous product uses HS 2827.32, while the 74 % powder, pellets and flakes are grouped under HS 2827.31.

What incoterms are commonly used for these chemical shipments?

Buyers and Chinese chemical exporters typically operate on FOB (Free on Board) or CIF (Cost, Insurance, Freight) terms, depending on the buyer’s preferred responsibility for freight and insurance.
