Transport classification per the UN Model Regulations / 49 CFR 172.101 Hazardous Materials Table. Confirm against the grade-specific SDS (Section 14) before shipping.
Nitric acid (HNO3, CAS 7697-37-2) is a strong mineral acid, supplied here as a technical-grade 67% (42 Baume) aqueous solution. Established uses include manufacture of ammonium nitrate fertilizer, metal pickling, cleaning, and etching, production of nitrates, nitro compounds, and explosives, and service as a wet etchant in semiconductor manufacturing.
Frequently Asked Questions
What is 42 degree Baume nitric acid?
42 Baume nitric acid is a concentration designation — it corresponds to roughly 67% HNO3 aqueous solution, the technical grade supplied here (CAS 7697-37-2). The Baume scale is a density measure historically used to specify acid strength. RawSource supplies it in bulk.
What is the difference between 40 and 42 degree Baume nitric acid?
The Baume number tracks solution density, so a higher Baume reading corresponds to a higher acid concentration; 42 Baume (≈67% HNO3) is more concentrated than 40 Baume. Always confirm the exact assay on the Certificate of Analysis rather than relying on the Baume label alone.
What is nitric acid 67% used for?
Established uses include ammonium nitrate fertilizer manufacture (neutralization with ammonia), metal pickling, cleaning and etching, production of nitrates, nitro compounds and explosives, and use as a wet etchant in semiconductor manufacturing. RawSource supplies the technical 67% (42 Baume) grade in bulk.
How does nitric acid 67% 42 Baume ship under DOT?
It ships as a regulated corrosive under UN 2031 (Nitric acid, other than red fuming). Packaging, labeling, and carrier requirements must follow the SDS and applicable transport regulations; RawSource provides shipping documentation and an SDS with each bulk order. Confirm packing group and handling with your carrier.
What is the cost of bulk nitric acid 67% 42 Baume technical grade?
Bulk pricing depends on packaging, volume, and delivery point given the regulated nature of the product. Request a quote from RawSource with your target quantity (drums, totes, or bulk) for current landed pricing, CoA, and SDS.
