Regulatory restriction status
Red Lead (Lead Tetroxide, Pb3O4) (CAS 1314-41-6) appears on the regulatory list(s) below. This is public regulatory information about the substance — not a statement about any specific supplier’s material, and not a safety claim. Confirm the current status for your jurisdiction and intended use.
- REACH SVHC Candidate List (EU): listed 19 Dec 2012 on the basis of toxic for reproduction (Art. 57(c)). SVHC status triggers EU supplier-communication and notification duties above 0.1% w/w; it is not, by itself, a ban on sale.

Frequently Asked Questions
What is red lead powder used for?
Red lead (lead tetroxide, Pb3O4) is used as a bright red-orange pigment in lead glass, glass containers, ceramic glazes, and paints. It is also a component of battery anodes and lubricant coatings and serves as a chemical intermediate and catalyst.
How is red lead oxide made?
Red lead is produced by oxidizing lead monoxide (litharge, PbO) in air at elevated temperature, converting it to lead tetroxide (Pb3O4). The reagent grade is a refined, high-purity bright red-orange powder.
What industries use litharge?
Litharge (PbO) and its higher oxide red lead (Pb3O4) are used in lead-acid battery manufacture, glass and ceramics, pigments, and as catalysts and chemical intermediates. RawSource supplies the red lead (Pb3O4) reagent grade for these uses.
What is the chemical formula and CAS number for red lead?
Red lead is lead tetroxide with formula Pb3O4 and CAS number 1314-41-6. It classifies under HS code 2824.90 (red lead and orange lead) and is supplied as a reagent-grade powder.
How do I get bulk pricing and documentation for red lead reagent?
RawSource supplies the red lead reagent powder with a CoA and SDS on every order. Submit an RFQ with your purity grade, volume, and packaging requirements for a current bulk quote; consult the SDS for handling and transport classification.
What is the REACH and TSCA regulatory status of Red Lead (Lead Tetroxide, Pb3O4)?
Red Lead (Lead Tetroxide, Pb3O4) (CAS 1314-41-6) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 215-235-6).
