About Western Min Metals (Sc) Corporation - Other Ores & Minerals Supplier in China

Western Min Metals (Sc) Corporation is based in China and currently lists 23 active products. Its catalogue focuses on high‑purity metal oxides and silicon compounds that fall under the categories Other Ores & Minerals and Industrial Chemicals. Products include Lanthanum Oxide (HS 2846.10, 99.999 % purity), Gadolinium Oxide (HS 2846.90), High Purity Silicon Dioxide, Indium Oxide (HS 2825.90, 99.99 % grade), and Cobalt Oxide (HS 2822.00). Several rare‑earth oxides such as Dysprosium Oxide (HS 2846.90, 99.5 % purity) and Yttrium Oxide (HS 2846.90, up to 99.999 %) are also listed. Additional items cover antimony, bismuth, molybdenum and various other oxides, each identified with the appropriate HS code where provided.

Product Range and Specialties of Western Min Metals (Sc) Corporation

Western Min Metals’ catalogue covers a spectrum of inorganic oxides used in electronics, catalysts, ceramics and metallurgical processes. Lanthanum, Gadolinium, Dysprosium and other rare‑earth oxides are commonly supplied in 5N (99.999 %) or 4N (99.99 %) grades, with impurity limits for Fe, Si and Al typically below 100 ppm. High‑purity silicon dioxide is usually marketed as 99.999 % (ICUMSA 45) grade and may be offered in micron‑sized powder or fused silica forms. Indium oxide and antimony tin oxide are standard in transparent conductive oxide applications, where resistivity and optical transmission are key specifications. Cobalt oxide and molybdenum oxide are typical precursors for battery cathodes and high‑temperature alloys, with particle size distributions often controlled under 10 µm. Buyers also encounter antimony trioxide and bismuth oxide in flame‑retardant and specialty glass formulations, where moisture content below 0.1 % and bulk density specifications are routine.

Trade and Export Information - Western Min Metals (Sc) Corporation

China is a global exporter of high‑purity inorganic oxides, and shipments of HS 2846 (rare‑earth oxides) and HS 2825 (indium, antimony, bismuth oxides) regularly flow to East Asian manufacturers, European chemical distributors and North American research institutions. Typical import destinations include Japan, South Korea, Germany, the United Kingdom and the United States, where the oxides are used in semiconductor manufacturing, advanced ceramics and renewable‑energy technologies.

Export transactions usually follow FOB Shanghai or Ningbo, with container loads of 20 ft (≈ 10 t) or 40 ft (≈ 20 t) depending on product density. Buyers often require compliance with ISO 9001 quality management, REACH registration for EU markets, and Material Safety Data Sheets (MSDS) for handling. Inspection agencies such as SGS or Bureau Veritas may be engaged for pre‑shipment sampling, and certificates of analysis (CoA) are standard accompanying documents. Chinese customs apply export licensing for certain rare‑earth oxides, so verification of the supplier’s export permit is a common prerequisite.

Sourcing from Western Min Metals (Sc) Corporation - Buyer Guidance

Prospective buyers should request a current Certificate of Analysis that lists purity, impurity profile (Fe, Si, Al ppm), moisture content and particle size distribution for each oxide. For rare‑earth oxides, an ICP‑OES or XRF report confirming the REO content (e.g., ≥ 99.5 % for Dysprosium Oxide) is advisable. Verification of the HS code on the commercial invoice helps ensure correct tariff treatment.

Standard documentation includes a Material Safety Data Sheet, REACH compliance statement for EU shipments, and, where available, ISO 9001 certification. Minimum order quantities for high‑purity oxides typically start at 500 kg per batch, but larger orders of 5 - 10 t are common for industrial users. Lead times of 30 - 45 days are typical after receipt of a signed purchase order and payment of any required export licence fees.

What purity grades are offered for the rare‑earth oxides?

The catalogue lists grades up to 99.999 % (5N) for oxides such as Lanthanum Oxide, Gadolinium Oxide and Yttrium Oxide, with lower grades of 99.9 % - 99.99 % also available for many items.

Which HS codes correspond to the listed products?

Products are classified under HS 2846.10 for Lanthanum Oxide, HS 2846.90 for most rare‑earth oxides, HS 2825.90 for Indium Oxide, Antimony Tin Oxide and Bismuth Oxide, HS 2825.80 for Antimony Trioxide, and HS 2822.00 for Cobalt Oxide.

What documentation should I obtain before placing an order?

Request a Certificate of Analysis, a Material Safety Data Sheet, REACH compliance evidence for EU shipments, and, if applicable, an ISO 9001 quality management certificate.

How are the oxides typically packaged for export?

High‑purity oxides are commonly packed in sealed 25 kg steel drums, 1‑ton IBCs, or bulk bags, and then loaded into 20 ft or 40 ft containers to protect against moisture and contamination.

Which regions most frequently import these Chinese oxides?

Major import markets include Japan, South Korea, Germany, the United Kingdom and the United States, where the materials are used in electronics, catalyst production and advanced material research.

What are the usual minimum order quantities and lead times?

Minimum orders are generally 500 kg per product, with larger industrial orders of several tonnes. Lead times range from 30 to 45 days after order confirmation and receipt of any required export licences.

Are any certifications typically required for these chemicals?

Buyers commonly require ISO 9001 quality certification, REACH registration for EU destinations, and a valid MSDS; these should be confirmed with the supplier prior to shipment.

How is product quality verified for items like silicon dioxide?

Quality is usually confirmed by a Certificate of Analysis that includes purity (often 99.999 %), moisture content below 0.1 %, and particle size distribution; independent testing by accredited labs such as SGS can be requested for additional assurance.
