Western Min Metals (Sc) Corporation offers antimony trioxide (Sb2O3) in two high‑purity grades, 4N at 99.99 % and 5N at 99.999 %. The 4N grade limits lead, arsenic, iron, copper, nickel, aluminium and calcium each to ≤5 ppm and bismuth to ≤2 ppm. The 5N grade tightens impurity limits to ≤0.5 ppm for silver, copper, aluminium, nickel and lead, while magnesium, calcium and iron are each ≤1 ppm. Both grades are supplied as a fine powder with particle size ranging from 1 µm to 4 µm and packed in 25 kg cardboard drums.
Antimony oxide of this purity is commonly used as a flame‑retardant synergist in engineering plastics and coating formulations, where low impurity levels prevent discoloration. In the glass and ceramic industries it serves as a clarifying agent, benefiting from the fine particle distribution that promotes uniform melt behaviour. Typical industry practice specifies bulk density around 3.2 g cm‑3 and moisture content below 0.5 % to maintain flowability, which aligns with the supplied material. Standard packaging for bulk chemical powders includes sealed drums with moisture‑resistant liners, a practice reflected in the 25 kg drums offered here.
Buyers such as polymer manufacturers, coating producers, and glass‑ceramic fabricators frequently source this grade for high‑performance applications. Importers should verify the exact grade, impurity certification, and drum integrity before confirming an order. Trade terms, minimum order quantities, and Incoterms are negotiable directly with Western Min Metals, and the supplier’s harbour‑tier verification indicates a vetted trading partner.

Before placing an order with Western Min Metals, importers should verify the exact purity grade required for their application and obtain a current Certificate of Analysis that lists impurity concentrations. Confirm that the 25 kg drums are sealed and that the packaging meets any regulatory requirements for hazardous chemicals in the destination country. It is also advisable to request a sample batch to evaluate particle size distribution and bulk density against the typical values provided.
Logistics for the antimony oxide are typically arranged on an FOB or CIF basis from the port of Shanghai, but the specific Incoterm should be agreed with the supplier. Since the listing does not state lead‑time, ask Western Min Metals for an estimated production and shipping schedule, taking into account customs clearance in China. Payment terms are usually negotiated per transaction and may include a letter of credit or advance payment, depending on the buyer’s risk profile.
During the import process, buyers often engage a third‑party inspection agency to verify batch conformity with the declared impurity limits and particle size range. Request the supplier’s material safety data sheet and any relevant export licences to ensure compliance with both Chinese and importing‑country regulations. Maintaining accurate documentation, including the COA and shipping certificates, will facilitate customs clearance and protect against disputes over product quality.
