Potassium Iodide Price Trend and Forecast 2026-2027

Key Takeaways

• Global potassium iodide prices firmed through 2025, with the global average climbing from USD 51.88/KG in Q1 to USD 57.51/KG by Q4 and holding near USD 57.47/KG in Q1 2026, as iodine costs stayed historically high.
• Northeast Asia saw the strongest climb, rising from USD 49.93/KG in Q1 to USD 59.02/KG by Q1 2026 on firm iodine costs and steady pharmaceutical demand.
• India traded in a USD 53.83 to 57.51/KG band, peaking late in the year before easing to USD 55.91/KG in Q1 2026, supported by proximity to Asian supply and large pharmaceutical and feed demand.
• The market traded at a high absolute level because potassium iodide is roughly three-quarters iodine by weight, the most iodine-heavy product in these reports, so its price closely shadows the iodine market.
• The potassium iodide market forecast for the rest of 2026 leans broadly stable to slightly soft, with pharmaceutical and feed demand setting a floor while gradual iodine-cost relief caps the upside.

What Is Potassium Iodide and Why Does It Matter?

Potassium iodide, written as KI, is a white crystalline salt and one of the most important iodine compounds in medicine and nutrition. It is made by reacting iodine with a potassium base, which ties its cost almost entirely to iodine. Because the salt is roughly 76 percent iodine by weight, it is even more iodine-dominated than potassium iodate, and iodine is one of the more expensive industrial minerals, mined from a small number of sources concentrated in Chile and Japan.

From a market view, potassium iodide is a small-volume, high-value specialty whose pricing rides the iodine cycle. Its highest-value role is pharmaceutical: it is used in thyroid treatment, as an expectorant, and in radiation-protection tablets, where it is stockpiled by governments and health systems. It also serves animal nutrition, food and salt fortification, and a shrinking photographic niche. That blend of medical and nutritional demand gives the market a defensive quality, while the price tracks iodine far more than general industrial activity.

Which Sectors Are Driving Potassium Iodide Demand?

• Pharmaceuticals: the largest value pool. Potassium iodide is used in thyroid treatment, expectorant formulations, and radiation-protection tablets, the last of which is stockpiled by governments, which gives demand a defensive and occasionally spiky character.
• Animal Feed and Nutrition: iodine supplementation in livestock and poultry premixes is a steady secondary outlet tied to meat and dairy production.
• Food and Salt Fortification: potassium iodide is used to iodise salt in some regions, an alternative to iodate that is favoured where storage conditions are cooler and drier.
• Analytical and Industrial: it serves as a laboratory reagent and in select industrial chemistry, a niche but reliable outlet.
• Photography and Imaging: historically a large use, now much diminished as film and traditional imaging have given way to digital.

Global Potassium Iodide Price Trend in 2025

Global potassium iodide prices firmed through 2025. As with iodate, the driver was iodine, which held close to the peak it had reached on tight Chilean and Japanese supply. The global quarterly average climbed from USD 51.88/KG in Q1 to USD 57.51/KG by Q4, a gain of around 11 percent.

Q1 2026 held near USD 57.47/KG. The climb was orderly, reflecting a market where pharmaceutical and nutritional demand is steady and price-insensitive at the margin. Because potassium iodide is the most iodine-heavy product in these reports, it carried one of the highest absolute prices, shadowing iodine more closely than any other compound covered here.

What Were India’s Potassium Iodide Price Trends in 2025?

India is a major consumer of potassium iodide through its large generic pharmaceutical industry and its animal-nutrition sector, and it leans on imports and regional supply to meet demand. Prices here track Asian iodine derivatives plus a premium for freight and the rupee, with sizeable pharmaceutical volumes giving Indian buyers some negotiating weight.

Indian prices rose from USD 53.83/KG in Q1 2025 to USD 57.51/KG by Q4, then eased to USD 55.91/KG in Q1 2026 as iodine costs steadied. Pharmaceutical formulators and feed-premix makers, the core buyers, purchased on steady schedules, so the climb reflected input costs rather than stronger demand.

Northeast Asia Potassium Iodide Price Trends in 2025

Northeast Asia combines iodine-derivative capacity with deep pharmaceutical and electronic demand, and its prices track the iodine market closely.

Regional prices climbed from USD 49.93/KG in Q1 2025 to USD 57.50/KG by Q4 and USD 59.02/KG in Q1 2026, the strongest run in this report, as firm iodine costs and steady downstream buying kept the trend pointed up all year.

What Factors Drove Potassium Iodide Costs in 2025?

• Iodine prices. The overwhelming driver. Potassium iodide is roughly three-quarters iodine by weight, so iodine cost sets the floor and the direction. Iodine easing from its peak was the main reason iodide prices softened.
• Concentrated iodine supply. Iodine comes from a small number of sources in Chile and Japan, so supply discipline and any disruption there move the iodide market faster than demand shifts.
• Defensive pharmaceutical demand. Thyroid treatment, expectorants, and radiation-protection stockpiling give demand a steady, price-insensitive floor that held volumes firm.
• Purity specifications. Pharmaceutical-grade iodide commands premiums and limits substitution, especially in Europe and North America where documentation requirements are strict.
• Stockpiling activity. Government and institutional purchases of radiation-protection tablets can add occasional, lumpy demand that firms pharmaceutical-grade pricing.
• Currency and freight. A soft rupee and a volatile real shaped import economics for India and Brazil, though iodine’s high value keeps freight a small share of landed cost.

Potassium Iodide Market Forecast for 2026

The potassium iodide market forecast for the rest of 2026 leans broadly stable to slightly soft. Iodine costs look set to ease further or hold, which would keep iodide prices flat to gently lower. Pharmaceutical and nutritional demand should stay steady regardless of the price path, with occasional firmness from stockpiling.

The bull case is renewed iodine tightness from its concentrated supply base, which would lift iodide quickly given the weight of iodine in the product, possibly amplified by a wave of government stockpiling. The bear case is continued iodine cost relief passing through into lower prices. Demand volumes are unlikely to fall much, because the core uses are medical and nutritional.

Expected Potassium Iodide Price Range (remainder of 2026)

Europe stays the outlier on the upside on pharmaceutical-grade supply and specifications. India holds the low end on Asian supply and large pharmaceutical demand. South America benefits from proximity to Chilean iodine, while the whole market remains historically expensive on iodine’s elevated base.

Key Analyst Insights for the Potassium Iodide Market

• Iodide is the purest iodine play in these reports. At roughly three-quarters iodine by weight, its price tracks iodine more closely than any other compound covered here.
• Demand is defensive and occasionally spiky. Pharmaceutical and nutritional uses give a steady floor, while radiation-protection stockpiling can add sudden, lumpy demand.
• Supply concentration is the key risk. Iodine comes from a handful of Chilean and Japanese sources, so any disruption there is the main upside threat to iodide prices.
• Pharmaceutical grade is the defensible niche, far less exposed to price competition than standard material and supported by strict documentation and purity requirements.
• The photographic decline is largely behind the market. With imaging demand already small, future direction rests on pharmaceuticals, nutrition, and iodine supply rather than legacy uses.

Key Takeaways for Buyers and Manufacturers

For Buyers

• Track iodine as the leading indicator. Iodide prices follow iodine almost directly, so watch the iodine market rather than general chemical benchmarks.
• Lock cover when iodine dips. Because iodine drives most of the cost, buying forward during iodine softness is the clearest way to manage iodide spend.
• Prioritise certified supply for pharmaceutical use. Documentation and purity matter far more than small price differences in regulated applications.
• Plan for stockpiling-driven spikes. Where radiation-protection demand is relevant, build supply agreements that can absorb sudden volume.

For Manufacturers

• Iodine sourcing is the whole game. Securing reliable, competitively priced iodine feedstock is the single biggest lever on iodide margins.
• Pharmaceutical grade holds value. Medical-grade iodide is far less exposed to price competition than standard industrial material.
• Supply continuity is a differentiator. Pharmaceutical and stockpiling buyers value dependable delivery and documentation over marginal price.
• Manage iodine price risk. Forward contracts or hedging on iodine smooth the margin volatility that comes with such an input-dominated product.
