Chlor-alkali Group


“By strengthening the business foundation and increasing cost-competitiveness, we aim to establish a revenue base that is resistant to market fluctuations.”

  • Message from the Group President

    As a supplier of commodity products, the Chlor-alkali Group is expected to ensure a stable supply of high-quality products for use internally, within Tosoh, and externally, by wide-ranging customers. We must keep pace with growth markets by increasing the scale of our business and by enhancing its cost-competitiveness.

    We will strengthen the foundation of our chlor-alkali business and consider increasing our chlor-alkali production capacity. Our urethane business, meanwhile, will see us promote added-value products to build a revenue base less susceptible to influence from fluctuations in the market than commodity products.

    We must, moreover, develop markets overseas to expand our business and increase its profits. The role of the management team is to develop a framework within which employees can gather various experiences from the early stages of their careers to cultivate personnel suited to handle business operations in the future.

  • Results

    Fiscal Year 2019 Results

    Net-sales-CA-02-02-02.jpg            Operating-Income-CA-03-03-03.jpg

    The Chlor-alkali Group’s net sales rose ¥2.4 billion, or 0.7%, to ¥337.4 billion (US$3.0 billion) in fiscal 2019. Its operating income, however, fell ¥20.6 billion, or 31.0%, to ¥46.0 billion (US$415 million), primarily because of worsening trade conditions.

    Domestic and export shipments of caustic soda were strong. Although market conditions overseas worsened, export product prices decreased in tandem with increased domestic product prices. Vinyl chloride monomer (VCM) export shipments and prices increased, driven by improvements in VCM market conditions overseas. Shipments domestically and abroad of polyvinyl chloride (PVC) resin diminished as a result of lessened production volume, but PVC prices rose because of upward revisions to domestic PVC prices and improvements in overseas PVC markets.

    Domestic shipments of cement were strong, but cement exports decreased. Market conditions abroad likewise deteriorated for methylene diphenyl diisocyanate (MDI), such that MDI export prices decreased.

  • Forecast

    Fiscal Year 2020 Forecast

    Fiscal 2020 net sales for the Chlor-alkali Group are projected to be ¥324.3 billion, for a decline of ¥13.1 billion compared with fiscal 2019. Sales volumes for urethane raw materials are forecast to increase, but net sales are nonetheless expected to decline, primarily because of worsening market conditions overseas for urethane raw materials and PVC.

    Operating income is expected to drop to ¥36.5 billion, down ¥9.5 billion from fiscal 2019. Although shipments of urethane raw materials and PVC are thought to increase, earnings are forecast to decline and fixed costs to increase. This is attributable to deteriorating market conditions overseas, particularly for urethane raw materials.
