Commodities for Chemical Processing

For a chemical processor, commodity chemicals are raw materials, so consistency and documentation weigh as much as price. This family supplies the core mineral acids and bases of synthesis and utilities: Nitric Acid (68-70% HNO₃) for oxidation processes and metal-precipitation duties; Sulfuric Acid (93-98% H₂SO₄) for pH regulation and as a general process reagent; Hydrochloric Acid (30-37% HCl) for pH adjustment and equipment descaling; and Sodium Hydroxide (Caustic Soda) (30-50% NaOH) for neutralisation across the plant. Sodium Nitrite (≥ 98.5% NaNO₂) stands apart as a true synthesis reagent — used in chemical synthesis routes such as diazotisation as well as in textile-dyeing support — and it also protects closed cooling loops on the utility side. Procurement questions for this industry are specification questions: request the full product specification and a batch analysis document with each delivery, confirm the assay and impurity limits your process actually needs rather than over-specifying, and agree sampling and retention procedures. Logistics follow chemistry: acids and caustic move in 200 L drums, IBCs, and bulk tankers, while Sodium Nitrite ships as a crystalline solid in 25 kg and 50 kg bags with a 24-month shelf life. Ask for storage-material guidance per product and SDS documentation aligned with your site's hazard-management system.
