Welcome to Tianjin Xingyu Fertilizer Industry Co., Ltd. (XYF), a premier mgo powder supplier and global chemical exporter based in Tianjin, China. Established in 1993, XYF brings over 30 years of manufacturing excellence to the global market, producing high-grade magnesium oxide powder (CAS NO: 1309-48-4) alongside a comprehensive range of magnesium salts. We supply B2B procurement managers, agricultural distributors, and industrial compounders worldwide with consistent, factory-direct chemical raw materials.
Direct Mine Control & Purity: Unlike standard trading companies, XYF operates its own high-quality magnesium mine base in Liaoning Province. Sourcing directly from our mineral base ensures that our magnesium oxide powder maintains exceptional chemical purity, uniform reactivity, and minimal trace impurities across every batch.
Industrial Scale & ISO Quality Assurance: Backed by a strict ISO 9001-2015 management system, our facility operates modern production lines capable of supplying large-scale commercial orders. Every shipment undergoes rigorous laboratory testing and is backed by SGS certifications.
Port Proximity & Ocean Freight Savings: Located just 80 km from Tianjin Port and 15 km from major railway freight hubs, our strategic location significantly reduces inland transit fees, ensuring fast vessel loading and competitive landed prices.
