Your Reliable Caustic Soda Supplier Balkan Partner
Across the Balkans' industrial economy, an uninterrupted chemical supply chain is a competitive advantage — not a luxury. As an export-focused Caustic Soda Supplier Balkan manufacturers and utilities count on, SUHA International delivers a consistent, high-purity supply of caustic soda (sodium hydroxide, NaOH) to industrial centres from Sofia and Belgrade to Bucharest, Zagreb, Athens and Ljubljana, protecting your production from costly interruptions.
Whether you are searching for a sodium hydroxide supplier, a NaOH exporter, or a source of bulk caustic soda flakes, pearls and liquid across Southeast Europe, our network covers Bulgaria, Serbia, Romania, Croatia, Greece, North Macedonia, Albania, Bosnia and Herzegovina, Montenegro and Slovenia under one roof.
Caustic soda — chemical formula NaOH, CAS number 1310-73-2, molar mass 40 g/mol — is a strong alkaline base (pH >13 in solution) used across dozens of industries for pH control, acid neutralisation, saponification and metal processing. We supply it in three commercial forms: flakes (96–99% NaOH), pearls (99% NaOH) and liquid caustic soda (50% solution). Every shipment is inspected and ships with a batch-specific Certificate of Analysis (COA), backed by official identity data on ECHA and PubChem.
📊 Why the Balkans: from the Black Sea ports of Constanța, Varna and Burgas to the Adriatic gateways of Rijeka, Koper, Bar and Durrës, the region's textile, soap, pulp, food and water-treatment sectors all depend on a steady flow of sodium hydroxide — making a dependable Caustic Soda Supplier Balkan partner critical to keeping mills and plants running at capacity.
Industries served: water treatment, textiles, soap & detergent, pulp & paper, metal processing, food & beverage, chemicals.

How Caustic Soda Powers Balkan Industry
A dependable sodium hydroxide distributor is essential to the success of Southeast Europe's most vital sectors. Below are the primary Balkan industries we serve and the role caustic soda plays in each.
Water & Wastewater Treatment
Across Bulgaria, Romania, Greece and Serbia, utilities use NaOH to adjust pH, neutralise acidic effluent and precipitate heavy metals. Large plants favour 50% liquid caustic with metering pumps. See caustic soda for water treatment.
Textile Mercerization
Textile hubs in North Macedonia, Serbia, Bulgaria and Romania rely on caustic soda for cotton mercerization, scouring and desizing — boosting lustre, strength and dye uptake. See caustic soda in textiles.
Soap & Detergent
In Greece, Romania, Albania, Bosnia and Bulgaria, caustic soda saponifies fats into bar soap and powers liquid detergents. High-purity flakes ensure firm bars and uniform batch quality.
Pulp & Paper
In Romania, Bulgaria, Bosnia and Slovenia, NaOH drives kraft pulping ("white liquor"), fibre recovery in recycling and pH control during bleaching — where stable quality is critical.
Metal Processing
In Serbia, Romania, Croatia and Montenegro, NaOH solutions handle alkaline cleaning and degreasing, oxide and paint removal, and aluminium etching and finishing.
Food & Beverage
Food-grade NaOH supports Clean-in-Place (CIP) in dairies and breweries, bottle washing, pH adjustment and lye peeling — compliant with EU food hygiene rules.
Application & Form Matrix for Balkan Buyers
| Industry | Function of NaOH | Recommended Form | Key Balkan Hubs |
|---|---|---|---|
| Water Treatment | Neutralisation & metal precipitation | Liquid 50% / Flakes | Sofia, Bucharest, Athens |
| Textile | Mercerization & scouring | Flakes 98% | Skopje, Belgrade, Plovdiv |
| Soap & Detergent | Saponification of fats & oils | Flakes 98% / Liquid | Athens, Tirana, Sarajevo |
| Pulp & Paper | Kraft white liquor (delignification) | Flakes / Liquid | Danube corridor, Ljubljana |
| Metal Processing | Alkaline cleaning & etching | Flakes / Liquid | Belgrade, Zagreb, Bar |
| Food & Beverage | CIP cleaning & pH control | Pearls 99% (low dust) | Zagreb, Podgorica |

Why We Are a Trusted Caustic Soda Supplier Balkan Partner
Procurement managers need more than a quote — they need a Caustic Soda Supplier Balkan partner with batch consistency, absorbed logistics complexity and supply continuity across 12-month contracts. Here is what differentiates our offer.
Note: certification badges reflect standards our sourcing network operates to. Specific certificates are issued per shipment and available on request.
Safe Handling & Storage of Caustic Soda
Caustic soda is a Class 8 corrosive substance requiring proper protocols. We provide a full SDS with every order; see also the NaOH safety profile on PubChem and EU REACH.
Required PPE
Chemical-resistant nitrile or neoprene gloves, full-face splash goggles or shield, apron and rubber boots. Keep an eyewash station and safety shower within reach.
Storage
Store cool, dry and ventilated; keep bags sealed and elevated on pallets to prevent moisture absorption and caking. Use first-in, first-out (FIFO) rotation.
Segregation
Never store near acids, aluminium, zinc or tin — NaOH reacts and can generate flammable hydrogen gas. Provide secondary containment (bunding) for spills.
First Aid
Skin: flush with water 20 min. Eyes: rinse 30 min, do not rub, seek emergency care. Ingestion: do not induce vomiting; rinse mouth and seek medical help.
