Business Details

Manufactures and sells Caustic Soda, Soda Ash, Calcium Chloride, sodium bicarbonate, sodium silicate, hydrogen, Vinyl Chloride Monomer, PVC Resin, Propylene Oxide, Chlorinated Solvents, and other products. Supplies mainly to domestic and overseas industries such as chemicals, building materials, food, and water treatment, with large-scale electrolysis facilities centered on the Tokuyama Plant as a key strength. Affiliated companies include Sun Arrow Chemical Co., Ltd. (manufacturing and sales) and Tokuyama Soda Sales Co., Ltd. (sales). Under the Medium-Term Management Plan 2025, the segment is positioned to pursue efficiency improvements and secure stable earnings.

Recent Overview

Declining exports of Caustic Soda, a slump in Vinyl Chloride market conditions, and rising logistics costs combined to reduce both revenue and profit

In the Chemical Products segment for FY2026 (ending March 2026), net sales were ¥106,226 million (down 7.6% year on year) and operating income was ¥9,701 million (down 10.4% year on year), representing lower revenue and profit. Caustic Soda saw lower profit due to reduced export volume, Vinyl Chloride Monomer / PVC Resin due to a decline in overseas market conditions, and Soda Ash / Calcium Chloride due to lower sales volume and increased logistics costs. In the final year of the Medium-Term Management Plan 2025, the segment is summarized as having struggled due to deteriorating market conditions.

Key Products

product
Caustic Soda

Supplied to domestic and overseas industries such as chemicals, pulp and paper, textiles, food, and water treatment. Also exported, but in FY2026 (ending March 2026) export volume declined, contributing to lower profit.

product
Vinyl Chloride Monomer / PVC Resin

General-purpose resins used in building materials, pipes, films, and other applications. In FY2026 (ending March 2026), profit declined due to a decline in overseas market conditions for Vinyl Chloride Monomer.

product
Soda Ash / Calcium Chloride

Supplied for applications including glass, chemicals, food, and road de-icing. In FY2026 (ending March 2026), profit declined due to a decrease in sales volume as well as increased logistics costs.

product
Propylene Oxide / Chlorinated Solvents

Propylene Oxide is used as a raw material for urethane foam and similar products, while Chlorinated Solvents are used for metal cleaning, electronic component cleaning, and other purposes. These form a complementary product group within the Chemical Products segment.

Growth Drivers

  • Continued reduction of manufacturing costs and improvement of production efficiency
  • Improved profitability through domestic sales price revisions
  • Diversification of earnings through commercialization of new products such as magnesium hydride
  • Securing sales volume through recovery of export volumes for Caustic Soda and other products

Risks

  • Profit pressure from declining overseas market conditions for Vinyl Chloride products
  • Decrease in sales volume due to sluggish demand in domestic construction and manufacturing industries
  • Rising manufacturing costs due to surging raw material and fuel costs (electricity, naphtha, etc.)
  • Intensifying price competition due to increased rivalry from Chinese and other Asian competitors
  • Deteriorating profitability due to increased logistics costs
  • Lower earnings due to reduced export volume of Caustic Soda
