Import All Colors Iron Oxide — Buy in Bulk from Supplier in China

All Colors Iron Oxide from Xi'an Chengxian Chemical Co. Ltd is a series of synthetic inorganic pigments produced through controlled oxidation and precipitation processes. The range covers the full visible spectrum, including red, yellow, black and brown oxides, with particle sizes engineered for opacity and tinting strength in industrial applications. Each batch is tested for color consistency, lightfastness and chemical stability under UV exposure and alkaline conditions.

The pigments use hematite, magnetite and goethite as base minerals, with purity levels typically exceeding 95 percent for primary colors. Standard grades conform to ISO 1248 and ASTM D3721 for heavy metal content, with typical oil absorption values of 20 to 30 g/100g and pH ranges between 5 and 8 in aqueous slurry. These properties ensure compatibility with water-based and solvent-based binders, a key requirement for paint, coating and construction material manufacturers.

Primary buyers include paint producers, concrete and ceramic tile manufacturers, and plastics compounders seeking stable, non-bleeding colorants. The pigments are supplied in 25 kg multiwall paper bags with PE inner liners, palletized for bulk export. Buyers should confirm MOQ, Incoterms and lead time directly with the supplier, as these are not specified in the listing. The product is suited for FOB or CIF shipments from Chinese ports such as Qingdao or Shanghai.
