It is one of the three primary iron oxide pigments, alongside red (Fe\u2082O\u2083) and black (Fe\u2083O\u2084). This pigment is produced through a controlled precipitation process, typically involving the reaction of iron salts with alkalis, followed by oxidation and dehydration. The resulting hue ranges from a bright lemon yellow to a warm, earthy ochre, depending on particle size and manufacturing conditions. Its high tinting strength, opacity, and resistance to alkalis and weak acids make it indispensable in construction (concrete, bricks, roofing tiles), coatings, plastics, rubber, ceramics, and even cosmetics and food (E172). The global market for iron oxide yellow is driven by the booming construction sector, particularly in Asia-Pacific, and the increasing demand for eco-friendly, heavy-metal-free pigments.<\/p>\n<p>Unlike natural ochres, synthetic iron oxide yellow offers batch-to-batch consistency, superior color purity, and controlled particle morphology. It is also a critical component in the production of magnetic materials and catalysts. The pigment is typically supplied as a fine powder, with a specific gravity of 3.4\u20133.8 g\/cm\u00b3 and a pH range of 3.5\u20137.0. Its oil absorption value is generally between 25\u201335 g\/100g. The CAS number for iron oxide yellow is 51274-00-1, and it is classified under HS Code 2821.10.00 (Iron oxides and hydroxides).<\/p>\n<h2 id=\"toc-205616b872841d48f2e21c7dda5d0e7c\">Global Top 10 Iron Oxide Yellow Suppliers &#038; Manufacturers (2025 Ranking)<\/h2>\n<p>The global iron oxide pigment market is consolidated, with a few multinational corporations dominating supply.

Choose 311 for coatings, 313 for plastics.<\/li>\n<li><strong>Q: Is iron oxide yellow toxic?<\/strong> A: No. It is non-toxic, non-carcinogenic, and approved for food contact (E172) and cosmetics by FDA and EFSA.<\/li>\n<li><strong>Q: Can iron oxide yellow be used in exterior concrete?<\/strong> A: Yes, but ensure it is alkali-resistant (pH 12-13). Grade 313 is recommended for concrete.<\/li>\n<li><strong>Q: What is the shelf life of iron oxide yellow powder?<\/strong> A: Minimum 2 years if stored in a dry, cool place (below 40\u00b0C) away from direct sunlight.<\/li>\n<li><strong>Q: How to improve dispersion in water-based paints?<\/strong> A: Pre-wet the pigment with a wetting agent (e.g., polyacrylate) and use high-shear mixing at 2000-3000 rpm for 15 minutes.<\/li>\n<li><strong>Q: What is the typical particle size?<\/strong> D50 is 0.2-0.5 \u00b5m for standard grades, 1-5 \u00b5m for micronized grades.<\/li>\n<li><strong>Q: Does iron oxide yellow fade in UV light?<\/strong> A: No. It has excellent lightfastness (8\/8 on Blue Wool Scale).<\/li>\n<li><strong>Q: Can it replace cadmium yellow?<\/strong> A: Yes, in most applications. Iron oxide yellow is less bright but more stable and non-toxic.<\/li>\n<li><strong>Q: What is the HS Code for iron oxide yellow?<\/strong> A: 2821.10.00 (Iron oxides and hydroxides).<\/li>\n<li><strong>Q: How to test for heavy metals?<\/strong> A: Use ICP-MS or AAS.

Top suppliers like Ningbo Yinyuan offer FOB prices from $800\/MT for Yellow 311.<\/li>\n<li><strong>Q: What is the best iron oxide yellow for concrete bricks?<\/strong> A: Grade 313 (reddish-yellow) is recommended for concrete due to its high alkali resistance. Dosage: 3-5% by cement weight.<\/li>\n<li><strong>Q: How to get a free sample of iron oxide yellow?<\/strong> A: Most Chinese suppliers (e.g., Hefei Yipin) provide 500g free samples. You only pay for shipping (DHL\/FedEx).<\/li>\n<li><strong>Q: Is iron oxide yellow cheaper than cadmium yellow?<\/strong> A: Yes. Iron oxide yellow costs $800-1,500\/MT, while cadmium yellow costs $20,000-50,000\/MT.<\/li>\n<li><strong>Q: Can I use iron oxide yellow in food packaging?<\/strong> A: Yes, if it is E172 compliant. Ensure the supplier provides FDA or EFSA certification.<\/li>\n<li><strong>Q: What is the minimum order quantity for iron oxide yellow from China?<\/strong> A: Standard MOQ is 1 MT for standard grades, but some SMEs accept 500 kg for trial orders.<\/li>\n<li><strong>Q:\u4e2d\u56fd\u304b\u3089\u30a2\u30e1\u30ea\u30ab\u3078\u306e\u914d\u9001\u306b\u306f\u3069\u306e\u304f\u3089\u3044\u6642\u9593\u304c\u304b\u304b\u308a\u307e\u3059\u304b\uff1f<\/strong> A: Sea freight takes 25-35 days (FOB Ningbo to Los Angeles).
