Buy Sulfuric Acid (SA) in Bulk, Drums & IBCs – Fertiliser, Metal Processing, Water Treatment & Marine Applications
Rotterdam Chemicals Group supplies Sulfuric Acid (SA), also referred to as Sulfuric Acid, to industrial and marine customers across Europe and international markets. As one of the most widely produced mineral acids globally, Sulfuric Acid underpins critical value chains including fertilizer manufacturing, chemical processing, metal treatment, petroleum refining, battery production, industrial water systems, and regulated marine applications.
Sulfuric Acid is typically supplied as a clear, dense, viscous liquid and is widely used both as a processing acid and as a key chemical intermediate in large-scale industrial operations. It is fully miscible with water, and dilution is highly exothermic, meaning heat is released rapidly when mixed with water. For safe handling, dilution and transfer operations must follow controlled procedures using compatible equipment and corrosion-resistant materials.
Typical industrial grades are supplied at ≥96% w/w concentration for performance and transport efficiency. Lower concentrations may be selected for controlled dosing, water treatment systems, or applications requiring reduced acidity and alternative handling considerations. Sulfuric Acid is non-flammable but highly corrosive.
Located near the Port of Rotterdam, we support bulk, drum, and IBC supply aligned with continuous production schedules, port-based operations, offshore installations, and global export logistics.
Wat is zwavelzuur (SA)?
Sulfuric Acid (CAS 7664-93-9) is a strong inorganic mineral acid with the molecular formula H₂SO₄ and a molecular weight of 98.08 g/mol. It is characterized by very high acidity and dehydrating capability, making it essential across multiple heavy industrial and processing environments.
Its strong proton-donating nature and affinity for water enable applications in acidulation, pH control, dehydration reactions, metal surface activation, and intermediate chemical synthesis.

Veelgestelde Vragen (FAQ)
What concentration of Sulfuric Acid is typically used in industrial processes?
Most industrial applications utilize concentrated grades around 96% w/w to optimize reactivity and minimize transport volume. Lower concentrations may be selected for controlled dosing, water treatment, or applications where process safety and infrastructure design require reduced acidity. Selection should align with the target process, materials compatibility, and regulatory framework.
What does UN 1830 classification mean?
UN 1830 refers to sulfuric acid solutions containing more than 51% acid concentration. Shipments are typically classified under ADR Class 8 as corrosive substances and commonly fall within Packing Group II for concentrated acid. Specific packaging, labeling, and transport conditions depend on concentration and the applicable transport mode.
Is sulfuric acid flammable?
No. Sulfuric Acid is classified as non-flammable. However, it is highly corrosive and generates significant heat when mixed with water. Safe handling requires controlled dilution procedures, appropriate PPE, and corrosion-resistant storage and transfer systems.
Can Sulfuric Acid be supplied for marine or offshore operations?
Yes. Sulfuric Acid can be supplied in bulk or containerised formats suitable for industrial port facilities, offshore installations, and regulated marine technical systems, subject to compliance with storage compatibility and transport classification requirements.
