When shipping sulfuric acid or caustic soda, shippers immediately classify these as Class 8 hazardous materials. Class 8 encompasses corrosive substances that chemically attack skin, eyes, organic materials, and corrode metals. Transport regulations mandate strict packaging, labeling, and documentation requirements; carriers often impose surcharges and demand specialized stowage plans. Distinguish from Class 3 (flammable liquids) or Class 6 (toxic substances) – corrosive effect is the defining characteristic.
