About Qingdao Freeworld International Trading Co., Ltd. - Industrial Chemicals Supplier in China

Qingdao Freeworld International Trading Co., Ltd. is based in China and currently lists six distinct chemical products in its online catalogue. The portfolio spans magnesium sulphate (commonly known as Epsom salt), magnesium fertilizer mono with a particle size of 2‑5 mm, magnesium acetate, magnesium oxide supplied at a minimum of 97 % purity, magnesium chloride, and calcium chloride marketed at 74 % industrial grade. Each item falls under the broader classifications of Industrial Chemicals, Organic Fertilizers, and Chemicals & Allied Products as indicated in the supplier’s top categories. The two products with explicit HS codes are magnesium oxide (HS 2519.90) and calcium chloride (HS 2827.20), both identified as industrial‑grade materials.

The supplier’s catalogue groups the magnesium compounds together, reflecting their common use in processing, water treatment, and agriculture. Calcium chloride is listed separately, aligning with its typical role as a de‑icing agent and a moisture‑control additive. The product titles follow standard industry naming conventions, allowing buyers to map them directly to HS‑code families used in customs documentation. No additional product specifications such as packaging size or purity beyond the stated minimums are provided in the source data.

Product Range and Specialties of Qingdao Freeworld International Trading Co., Ltd.

The six items offered include magnesium sulphate, magnesium fertilizer mono (2‑5 mm granules), magnesium acetate, magnesium oxide (97 % min), magnesium chloride, and calcium chloride (74 % industrial grade). In the global chemicals market, magnesium sulphate is usually supplied at 99 % purity for pharmaceutical or laboratory use, while industrial grades range from 95 % to 98 % for agricultural applications. Magnesium oxide grades are commonly categorized as 97 % (industrial), 99 % (technical) and 99.5 % (high‑purity), with particle sizes expressed in microns for refractory or ceramic uses. Calcium chloride is typically sold as 70 % - 80 % dry, with the balance being water of crystallisation; bulk shipments often use 25 kg bags or 1 ton bulk containers. Magnesium fertilizer mono granules of 2‑5 mm align with standard particle size specifications for controlled‑release nitrogen‑magnesium blends used in horticulture.

Trade and Export Information - Qingdao Freeworld International Trading Co., Ltd.

China is a major exporter of bulk inorganic chemicals, and the listed magnesium and calcium compounds are routinely shipped to markets in Southeast Asia, the Middle East, Europe and North America. HS 2519.90 (magnesium oxide) and HS 2827.20 (calcium chloride) fall under Chapter 25 and Chapter 28 respectively, which are subject to standard customs duties and may require a Certificate of Origin and a Material Safety Data Sheet (MSDS) for clearance. Buyers typically request ISO 9001 quality‑management certification, REACH compliance documentation, and third‑party test reports confirming purity and moisture content for these industrial chemicals. Common logistics involve 20‑ft or 40‑ft containers packed in fiber‑board boxes or bulk bagging, with FOB Qingdao or CIF destination being standard Incoterms used by Chinese exporters.

Sourcing from Qingdao Freeworld International Trading Co., Ltd. - Buyer Guidance

When sourcing magnesium oxide or calcium chloride from this supplier, request a recent Certificate of Analysis that lists purity (≥97 % for MgO, ≥74 % for CaCl₂), moisture level, and particle‑size distribution. An up‑to‑date MSDS is essential for handling and transport compliance, and buyers should verify that the supplier can provide ISO 9001 or equivalent quality‑system documentation if required by the importing country. For the granular magnesium fertilizer, ask for a sieve‑analysis report confirming the 2‑5 mm size range, as well as any agronomic test data that demonstrate nutrient release characteristics. Confirm packaging details (e.g., 25 kg bags, bulk bags) and preferred Incoterms before finalising the purchase order.
