Sodium sulfide price per ton, per kg and per container
Two grades, one chemistry. Both are 60% active Na₂S flake in 25 kg bags; the difference is the guaranteed iron limit. Every figure below is derived from the per-ton price — 1 MT = 1,000 kg = 40 bags, and one 20ft container loads about 20 MT.
| Grade | USD / MT | USD / kg | USD / 25 kg bag | USD / 20ft FCL | USD / kg active | Specified for |
|---|---|---|---|---|---|---|
| Na₂S 60% flake — standard | $890 | $0.89 | $22.25 | $17,800 | $1.48 | Mining flotation, Kraft pulping, sulfur dyeing, effluent treatment, synthesis |
| Na₂S 60% flake — low iron, Fe ≤ 10 ppm | $940 | $0.94 | $23.50 | $18,800 | $1.57 | Leather dehairing and any process where iron staining of the end product matters |

What FOB does and does not include
FOB covers the goods loaded on board at Jebel Ali or Mersin. It excludes ocean freight, marine insurance, destination terminal handling, import duty and inland delivery.
Sodium sulfide moves as UN 1849, IMDG Class 8, so dangerous-goods surcharges apply and vary by carrier and route — a CFR number cannot be estimated from a standard freight table. Send your destination port and CFR, CIF, CPT or DAP is calculated properly.
Sodium sulfide market outlook: what is moving the price this quarter?
Na₂S has no published daily index. Its cost is set by sodium sulfate, reduction coal and furnace energy, and pressured from outside by the sulfur and ocean-freight markets. This is the snapshot behind the levels on this page as of .
📊 Current drivers
Sulfur is not the feedstock — but it sets the direction. Most sodium sulfide is made by reducing sodium sulfate with coal in a high-temperature furnace, so the direct cost base is salt cake, coal and energy. What changed in 2026 is the wider sulfur complex: Middle East supply disruption and China's restriction of sulfuric-acid exports from 1 May pushed benchmark sulfur sharply higher. QatarEnergy's monthly sulfur price went from US$520/t FOB in February to US$890/t in July, and was rolled over unchanged for August. That tightness removes the downside for sulfide chemicals, Na₂S included.
Freight is the bigger swing factor for buyers. Routing risk around the Strait of Hormuz and elevated ocean rates have added well over US$100/t to delivered bulk sulfur cargoes, and Class 8 dangerous-goods freight moves with the same market. For Na₂S the effect shows up in CFR and CIF quotes rather than in the FOB level, which is why comparing landed prices matters more this year than headline FOB.
Demand comes mainly from tanneries and textile dyehouses in South Asia, the Middle East and Africa, from mineral flotation and from pulp mills. Against that background the FOB levels on this page have been held unchanged at every weekly review since late August.
Outlook for the next 30–60 days: the working range is $880–$910/MT for the standard grade and $930–$960/MT for low iron, with the risk skewed upward — a further sulfur step-up, a freight spike or an interruption on Gulf shipping routes would move levels toward the top of those ranges well before anything moves them down.

Is the low-iron grade worth $50 a ton to you?
The premium is $50/MT, about 5.6% — $1,000 on a 20 MT container. Whether that is money well spent depends entirely on what iron does to your end product.
Buy low iron (Fe ≤ 10 ppm) if…
- You are a tannery — iron above roughly 15 ppm leaves dark iron-sulfide staining on finished crust that cannot be corrected without downgrading the hide
- You produce light or pastel shades where any discoloration is visible
- Your customer's specification names an iron limit in ppm
- One rejected hide batch costs you more than the $1,000 per container premium — which, for most tanneries, it does
Standard grade is enough if…
- You run mineral flotation — sulfidization does not care about trace iron
- You dose into Kraft white liquor, where the recovery cycle already carries metals
- You precipitate heavy metals from effluent — the iron ends up in the sludge either way
- You use it as a reducing agent in synthesis and your own specification sets no iron limit
Sodium sulfide order calculator: what your shipment costs
Pick the grade, enter your tonnage, and the FOB goods value is calculated with containers required, bag count and the cost of the active Na₂S you actually consume.
Based on 25 kg bags at 20 MT per 20ft container. FOB goods value only — freight, insurance, duty and destination charges are quoted separately against your port.
Indicative for budgeting, at levels valid until 28 September 2026. Send tonnage, grade and destination port for a firm, contractable offer with the TDS and COA format attached.
The cheapest per ton is not the cheapest per kilogram
Sodium sulfide is bought as tonnage but consumed as active chemical. Two offers at an identical USD/MT can differ by several percent in real cost — which is how a cheap-looking quotation turns expensive by the third container.
Step 1 — convert every offer to active content
One metric ton of 60% flake contains 600 kg of active Na₂S. So:
cost per kg active = price per MT ÷ (assay % × 10)At $890/MT that is $1.48 per active kilogram; at $940/MT it is $1.57. Run the division with the assay printed on the certificate of analysis, not the nominal grade on the offer sheet — material that assays 58% is about 3.4% more expensive per active kilogram than the same money at 60%.
Step 2 — subtract the tonnage you throw away
Water-insoluble matter is material you pay ocean freight on and then filter out. Every 1% of insolubles is 200 kg of a 20 MT container, so price it as waste plus disposal, not as product — and ask every supplier for their insolubles figure in writing.
Step 3 — compare landed, never FOB
Freight, insurance, terminal handling and duty are charged per container, not per ton, so they fall as a per-ton cost on a full load and rise sharply on part loads. Ask for FOB and CFR side by side to your own port; with 2026 freight volatility, the gap between them is your real decision.
Why some quotations look far cheaper than these
Headline numbers on trading platforms are frequently for a different product: a lower assay, an unstated iron level, higher insolubles, red flake instead of yellow, or a per-ton figure that assumes you accept the shipment without a batch certificate of analysis or inspection.
Before comparing anything, get four things in writing from each supplier — assay minimum, iron in ppm, water-insoluble maximum, and whether a batch COA and pre-shipment inspection are included. Then convert both offers to cost per kilogram of active Na₂S. That is the only comparison that survives contact with a real shipment.

What moves the sodium sulfide price
There is no published index for Na₂S. These are the variables behind the two numbers on this page, and how the levels are maintained.
Cost base
- Sodium sulfate and reduction coal — the feedstocks that set the floor
- Furnace energy — reduction runs at high temperature, so fuel and power feed straight through
- Sulfur complex — tight sulfur and sulfuric-acid markets limit the downside for every sulfide chemical
- Origin and utilisation — plant scale, export policy and turnarounds shift availability quickly
Specification
- Assay — contracted as a minimum, the basis of every honest comparison
- Iron limit — the $50/MT step between the two grades here
- Sulfite — a tight limit means fresh stock, not aged inventory
- Insolubles — the line between product and freight-paid waste
Freight & terms
- Class 8 surcharges — UN 1849 freight varies by carrier and route
- Destination — port, transit time and local handling
- Incoterm — FOB, CFR, CIF and CPT move different cost blocks
- Payment — L/C and D/P carry bank cost inside the quoted number
How these levels are maintained
- Basis — FOB Jebel Ali or Mersin, 25 kg bags, full container load
- Reviewed weekly, and whenever feedstock or freight moves sharply
- Excludes freight, insurance, duty, inspection and palletising
- Last reviewed
- Valid until
