Iran Caustic Soda Hub Price Map
All prices are USD/MT. Map labels show the representative midpoint for NaOH 98–99% flakes only; liquid NaOH rows are listed separately in the table.
Methodology and Commercial Scope
Hub validation
Only production zones, seaports and border corridors with current caustic soda product, freight or chemical-export evidence are included. General transit crossings without product-specific support are excluded.
Price construction
Ranges are anchored to publicly posted Iranian producer indications for NaOH 98–99% flakes and NaOH 48–50% liquid, then adjusted for verified route, packaging and terminal differences and checked against current regional benchmarks.
Comparable basis
Seaport rows use FOB and plant, rail or land-border rows use FCA. EXW, CFR, CIF and delivered prices are excluded. Map midpoints represent flakes only because liquid and solid prices are not directly comparable.

- These values are non-binding export planning indications for July 12, 2026; confirmed offers may move during the week.
- The price unit is USD per gross metric ton of product. A metric ton of 50% liquid contains approximately half a metric ton of NaOH, so liquid and flakes must not be compared on price per product ton alone.
- Standard export evidence supports NaOH 98–99% flakes in 25 kg two-ply PP/PE bags, commonly palletized or consolidated as 50 bags inside a 1,250 kg jumbo bag. Liquid NaOH 48–50% is commonly moved by bulk tanker, ISO tank, IBC or suitable drums, subject to carrier approval.
- Sodium hydroxide is Class 8 dangerous cargo. DG acceptance, container or tank availability, inspection, documentation and border or port operating conditions can materially change the final price.
- A firm quotation requires product form, grade, packaging, quantity, loading basis, destination, shipment window, payment terms, inspection requirements and required documents.
Caustic Soda Price FAQ
Are these prices binding offers?
No. They are public-market planning indications. A binding FOB or FCA offer requires a complete RFQ and confirmation of stock, loading slot, carrier acceptance and payment terms.
What does the map midpoint represent?
Each map number is the representative midpoint of the listed NaOH 98–99% flake rows at that hub. Liquid NaOH is excluded from the map midpoint to prevent an invalid comparison between concentrations.
Which grades and packs are normally exported?
The main solid export grade is NaOH 98–99% in 25 kg two-ply PP/PE bags, often palletized or consolidated inside a 1,250 kg jumbo bag. Liquid exports are normally NaOH 48–50% in approved bulk or packaged systems.
Why do FOB and FCA prices differ by hub?
Differences reflect inland freight, terminal handling, packaging, DG charges, equipment availability, route risk, customs procedures, quantity, documents, payment terms and loading timing.
