Import Active Zinc Oxide(Feed Grade) — Buy in Bulk from Supplier in China

Active zinc oxide from Xiangtan Swallow Chemicals is a feed-grade compound with the molecular formula ZnO and a molecular weight of 81.38. It appears as a yellowish, odourless powder with a bulk density of approximately 0.5 g/ml, a specific gravity of 5.67, and a melting point of 1975°C. The product is insoluble in water and alcohol but soluble in dilute acids, making it suitable for controlled release in animal feed applications.

This active zinc oxide variant contains a high Zn content (95 to 98 % as ZnO), with an average particle diameter of under 40 nm when measured by electron microscope and under 60 nm by XRD. The specific surface area is at least 40 m²/g, contributing to its high surface activity and energy levels. Impurities are tightly controlled, with lead limited to a maximum of 8 ppm, cadmium to 4 ppm, and manganese and copper each capped at 10 ppm. Volatile matter at 105°C does not exceed 0.7 %, while water-soluble matter and hydrochloric acid-insoluble content are kept below 0.7 % and 0.05 % respectively.

Primarily used in animal feed, this product helps reduce diarrhoea and supports ablactation while improving propagation. Its fine particle size enhances bioavailability, and its sterilising and astringent properties further benefit livestock health. The material is packaged in 25 kg net PP bags, with 26 metric tonnes fitting into a 20-foot container. Buyers typically source this for poultry, swine, and aquaculture feed formulations where zinc supplementation is critical.

Xiangtan Swallow Chemicals Co., Ltd. is based in Torch Industrial Park, Xiangtan, Hunan Province, China. The company operates as an importer-tier supplier, specialising in chemical compounds for industrial and feed applications. Its location in Hunan, a region with established chemical manufacturing infrastructure, positions it well for logistics and raw material sourcing.

The supplier’s profile indicates a harbor trust tier, though current response metrics are not available. The company focuses on producing active zinc oxide tailored for feed use, with documented specifications for purity, particle size, and impurity limits. No additional certifications, client lists, or operational history are provided in the available data, so buyers are advised to request these directly.
