⚠ Why these FOB levels differ from published spot indices

Published indices such as ICIS, ChemAnalyst or IMARC mostly track bulk contract cargoes and domestic assessments, which sit structurally below containerised business. Prices on this page are for containerised 1–3 FCL lots, and the FOB number already carries dangerous-goods port handling (UN 1823 / UN 1824, IMDG Class 8), premium 25 kg PP bagging, SGS/BV inspection readiness and the full export document set. Per-MT pricing for small parcels is structurally higher than bulk contract rates — that is a difference of trade format, not of product quality.

If you also buy soda ash or sodium hypochlorite, combining grades into one shipment usually improves the per-MT number.

Reading the market

Why published caustic soda price indices disagree with each other

Before you benchmark a quotation against an index, check that the two describe the same thing. For the same quarter and the same country, two major providers can be several hundred dollars apart — because they measure different purity bases, different trade formats and different delivery terms.

The three questions to ask about any caustic soda number. First, what basis? A 50% liquid quoted per ton of solution is roughly half the price of the same NaOH quoted on a 100% dry basis. Second, what trade format? Bulk contract parcels of thousands of tons price well below containerised 25 MT lots with bagging and dangerous-goods handling. Third, what Incoterm? An ex-works or domestic assessment carries no freight, no DG surcharge and no export documentation.

Until those three match, comparing two numbers tells you nothing. The figures on this page are stated unambiguously: USD per metric ton, FOB Jebel Ali or Mersin, containerised, 25 MT minimum, DG handling and export documents included.

Flakes or liquid — which is actually cheaper? Compare on contained NaOH, not on product weight. A 50% solution at $305/MT of solution is about $610 per MT of contained NaOH; flakes at $790/MT with 98% purity work out to about $806 per MT of contained NaOH. So liquid looks cheaper at the loading port — but you then pay ocean freight, terminal handling, duty and inland haulage on the water as well, which is what flips the landed comparison. Well inland from the discharge port, flakes almost always win. Liquid wins near the port and on handling: no bag opening, no dust, no dissolving step, and it removes the exotherm risk described in our guide to storing caustic soda safely. See also our flakes vs liquid comparison.

From FOB to landed cost

What the same cargo costs landed at your port

The prices above are FOB — the cargo loaded on board at Jebel Ali or Mersin. Add ocean freight on your lane and you get the CIF landed cost. Three worked examples for flakes 98%, calculated as the 10 September 2026 FOB base plus estimated freight for one 20' FCL. Destination terminal handling, duty, VAT and inland delivery are excluded.

Market intelligence

What is driving caustic soda prices in H2 2026?

Caustic soda and chlorine are co-produced in a fixed ratio — roughly 1.1 tonnes of NaOH per tonne of chlorine — so supply is set largely by chlorine and PVC economics, while demand comes from alumina, pulp and paper, textiles, soaps and water treatment. That mismatch is why the market behaves the way it does.

Downward pressure

  • China holds an estimated 35–40% of world chlor-alkali capacity, and annual additions of around 5% have outpaced its own demand growth
  • Softer alumina refining demand, including permanent refinery closures in Australia
  • Pulp and paper mill closures and curtailments in North America through 2025–2026
  • Competitive Asian import offers keeping European domestic levels under pressure

Upward pressure

  • Electricity is 40–60% of chlor-alkali production cost, so power tariffs feed straight through
  • Permanent European closures during 2025 — Fortischem, Spolana, Vencorex and Arkema Jarrie — with Dow signalling an exit from Schkopau by 2027
  • The March 2026 Strait of Hormuz disruption, which lifted North American prices about 3.7% and triggered dozens of force majeure declarations across Asia and the Middle East
  • Dangerous-goods handling adds roughly 15–30% over ordinary freight and is not easing

What to watch in Q4

  • Whether weak PVC margins force real chlor-alkali rate cuts rather than paper ones
  • Alumina restarts or further closures — the single biggest demand swing factor
  • Container availability for IMDG Class 8 on Gulf–West Africa lanes
  • Regional power tariffs going into the northern winter

Q2 2026 set the tone for the second half. Published assessments for the quarter showed increases almost everywhere: the United States up about 7% quarter on quarter, Japan up roughly 11% on LNG-linked power costs, Saudi Arabia up about 13% on export pull, Brazil up around 15% on freight, and Germany up more than 50% as maintenance-driven tightness collided with the 2025 capacity closures. Q3 is also the seasonally strongest quarter, when agricultural demand, restarting pulp procurement and peak textile production together typically add 3–8% to Asian FOB flake levels between late June and August.

That is the backdrop against which the September levels on this page sit — firm, but capped by Asian availability.

Why buy from Jebel Ali or Mersin rather than direct from China? Chinese FOB numbers can look considerably cheaper on paper, but the delivered comparison changes once you add 30–45 day transit against 3–16 days from the Gulf or Turkey, more working capital tied up in transit, letter-of-credit and re-routing risk, and destination restrictions on some Chinese-origin chemical shipments. For buyers running 1–3 containers at a time, these origins trade an FOB premium for short lead times, DG-compliant packing and documentation that clears without argument. More about how we work →

Methodology

How these caustic soda prices are assessed

Transparency matters when a number goes straight into your costing sheet. Here is exactly what these figures represent.

Source of the numbers

Ranges are built from SUHA International Trading's own confirmed offers and concluded export business out of Jebel Ali and Mersin during the current month, then cross-checked against published regional indices.

What is included

FOB at the named loading port, DG port handling for IMDG Class 8, export packing as stated, and the standard document set: invoice, packing list, B/L, COA, safety data sheet and certificate of origin.

What is not included

Ocean freight and marine insurance (unless CIF), destination terminal handling, import duty, VAT, inland delivery, demurrage, and any third-party inspection you order. Lane-by-lane freight sits on the price by country page.

Update cycle

Reviewed at the start of each month and whenever the market moves more than about 3%. Last review: . Issued quotes are firm for 7 days, subject to stock. Checks on arrival are covered in how to check caustic soda quality.

Outlook to year-end

Caustic soda price forecast for the rest of 2026

Projected FOB bands through to year-end. Asian oversupply and soft alumina and pulp demand cap the upside; power costs, the permanent European closures of 2025 and firm DG freight limit the downside. Treat these as planning ranges, not guarantees.

Procurement note: with the market range-bound rather than trending, buyers taking regular volume usually do better covering 50–60% on a quarterly contract and leaving the balance to spot, instead of trying to time a bottom. The CIF band above spans every destination in the price by country table, from the UAE at the bottom to deep-inland markets at the top.

Common questions

Caustic soda price FAQ

The questions buyers and search engines ask most about NaOH pricing, packing, classification and shipping.

As of , indicative export prices are $780–800/MT for caustic soda flakes (NaOH 98%), $560–630/MT for caustic soda pearls (NaOH 99%), and $270–340/MT for liquid caustic soda (NaOH 30–50%). All are FOB Jebel Ali (UAE) and Mersin (Turkey) and include dangerous-goods port handling. For the landed cost at your own discharge port, see the caustic soda price by country page.

Industrial caustic soda is traded per metric ton, not per kilo. At September 2026 export levels, flakes 98% work out to roughly $0.78–0.80 per kg FOB, pearls 99% to about $0.56–0.63 per kg, and liquid NaOH to approximately $0.27–0.34 per kg. Retail and small-pack prices are several times higher because they carry repacking, retail margin and small-quantity handling costs.

At September 2026 export levels a 25 kg bag of caustic soda flakes 98% works out to roughly $19.50–20.00 FOB, and a 25 kg bag of pearls 99% to about $14.00–15.75. Bags are not sold individually for export; the minimum is one full container of 25 MT, which is 1,000 bags for flakes or pearls.

Because they measure different trade. Published indices track bulk contract cargoes and domestic assessments; this page quotes containerised 1–3 FCL export lots whose FOB number already carries IMDG Class 8 port handling, 25 kg PP bagging, inspection readiness and the full document set. The indices also disagree with one another: for Q2 2026, ChemAnalyst assessed the United States at about $589/MT while IMARC put it at $358/MT for the same quarter. Always check what basis, purity and trade format a number refers to before comparing it with a quotation.

On our current September 2026 levels pearls are quoted lower, at $560–630/MT against $780–800/MT for flakes, even though pearls are the higher-purity grade. Pearls normally price at or slightly above flakes because prilling is an extra processing step, so a level below flakes reflects a specific origin position rather than a general market shift. Confirm the current pearls number with the desk before you build it into a costing.

Per ton of product, clearly yes: liquid at $270–340 against flakes at $780–800. Per ton of contained NaOH the gap narrows sharply: a 50% solution at $305 per MT of solution equals about $610 per MT of NaOH content, against roughly $806 per MT of NaOH content for flakes at $790. The comparison then flips on logistics, because you pay freight, handling and duty on the water as well. Flakes are usually the cheaper landed option well inland from the discharge port; liquid wins when you are close to the port and already have tanks and dosing infrastructure.

A 20-foot container takes about 25 MT of caustic soda flakes in 25 kg PP bags (1,000 bags, typically on 24 pallets), 25 MT of pearls, and 25 MT of liquid NaOH in a flexitank. The limit is payload weight, not volume, and several destination ports enforce road weight limits below the container maximum.

Solid sodium hydroxide, including flakes and pearls, is classified under HS 2815.11. Sodium hydroxide in aqueous solution, known as soda lye or liquid caustic, is HS 2815.12. Some countries add national digits after the six-digit heading, so check your own tariff schedule before filing.

For the remainder of 2026 we expect flakes 98% to hold in a $760–830/MT FOB band, pearls 99% at $555–640, and liquid NaOH at $265–345. Asian oversupply and softer alumina and pulp demand cap the upside, while high electricity costs, the permanent European chlor-alkali closures of 2025 and firm dangerous-goods freight limit the downside.

Ocean freight depends on the lane. Jebel Ali to Mombasa is roughly $70–90/MT, Jebel Ali to Colombo $60–80/MT, and Mersin to Lagos $130–170/MT. These are for one 20-foot FCL of 25 MT and exclude destination terminal handling, duty and inland delivery. Freight bands for 165 destinations are listed on the price by country page.

FOB (Free On Board) means the seller’s cost and risk end once the cargo is loaded at the origin port, so the buyer arranges and pays ocean freight. CIF (Cost, Insurance and Freight) means the seller pays freight and marine insurance to the named destination port. FOB gives the buyer freight control; CIF gives a single landed number to budget against. This page quotes FOB; the price by country page quotes CIF.

One 20-foot FCL: 25 MT for flakes in 25 kg PP bags, 25 MT for pearls, and 25 MT for liquid NaOH in flexitank or ISO tank. Buyers taking three or more containers per shipment, or committing to quarterly volume, generally price at the lower end of each range.

A standard export set includes the commercial invoice, packing list, bill of lading, certificate of analysis, safety data sheet, certificate of origin, and the Dangerous Goods Declaration required for IMDG Class 8 cargo. Third-party inspection by SGS or Bureau Veritas, and legalised documents, can be arranged where the destination requires them.

Yes. Caustic soda, sodium hydroxide and lye all refer to NaOH. Caustic soda is the industrial trade name, sodium hydroxide is the chemical name used on documentation and safety data sheets, and lye is the common name used in soap making and food contexts. Flakes, pearls, prills, pellets and 30–50% solution are physical forms of the same compound.

Yes. Solid caustic soda is UN 1823 and liquid caustic soda is UN 1824, both IMDG Class 8 (corrosive). Shipment requires compliant packaging, corrosive labelling, a Dangerous Goods Declaration and a safety data sheet. Carriers apply a dangerous-goods surcharge that typically adds 15–30% over comparable non-hazardous freight, and that surcharge is already built into the FOB prices on this page.
