Denka Company Limited announced it would record an extraordinary loss of approximately 16.1 billion yen (£85.8 million) as an impairment on manufacturing facilities at its US subsidiary. It will indefinitely suspend chloroprene rubber production at the Louisiana plant.

The Japanese chemical manufacturer, which holds a 70 percent stake in Denka Performance Elastomer LLC (DPE), cited mounting operational challenges, including unexpectedly high costs for pollution control equipment and declining production volumes at the American facility.

“DPE has faced significant cost, production and other challenges at its facility in the United States,” the company said in a statement. “Rising costs are attributable to, among other factors, identification, design, purchase, installation, and operation of pollution control equipment to reduce chloroprene emissions that DPE did not anticipate being required when it acquired the facility from E.I. DuPont de Nemours and Company.”

The subsidiary was established in December 2014 and acquired the chloroprene rubber business from DuPont in November 2015. The Louisiana facility was intended to serve as a second manufacturing site in North America, complementing Denka’s Omi Plant in Itoigawa, Niigata, Japan.

However, according to the company statement, DPE has struggled with multiple operational issues, including “rising energy costs and a shortage of qualified staff necessary to operate new pollution control equipment and implement other emission reduction measures. “

Production volumes have declined partly due to “operational restrictions arising from the pollution reduction measures and unscheduled plant outages associated with supply chain disruptions and severe weather events,” Denka said.

The company noted that these challenges, combined with changes in the global economic environment for chloroprene rubber, have pressured profitability, making near-term improvement difficult.

Denka confirmed that DPE employs 250 people as of December 2024 and will not restart its chloroprene rubber manufacturing facilities following a regular maintenance shutdown. Instead, “all options for the business, including a potential sale of the business or its assets, will be considered,” the statement said.

The company emphasised that “no decision regarding a permanent closure of the facility has been made at this time.”

Customers will continue to be supplied from current inventories and production at the company’s Omi Plant in Japan.

DPE is 70 percent owned by Denka USA LLC, a wholly owned subsidiary of Denka Company Limited, and 30 percent by Diana Elastomers, Inc., a subsidiary of Mitsui & Co., Ltd.

South Korean tyre maker achieves second consecutive quarterly revenue record despite raw material pressures

South Korean tyre manufacturer NEXEN TIRE reported record quarterly revenue for the second consecutive period on Thursday, posting consolidated sales of 804.7 billion won in the second quarter as increased European production capacity and recovering US demand offset global automotive sector uncertainties.

The company’s operating profit reached 42.6 billion won in the three months to June, remaining stable from the previous quarter despite ongoing pressure from elevated raw material costs that began in late 2024.

The strong performance was primarily attributed to enhanced production following the completion of Phase 2 expansion at NEXEN TIRE’s Czech Republic facility, combined with targeted regional sales strategies that secured key supply volumes across both original equipment and replacement market segments.

US sales strengthened further in the second quarter, building momentum from the first-quarter recovery after experiencing a temporary decline in the latter half of 2024. Expanded retail distribution partnerships supported the improvement, the company said.

In the Asia-Pacific region, Australia and Japan delivered record sales volumes, driven by continued investment in distribution network development.

Ocean freight costs provided some margin relief, though the company continued to face headwinds from raw material price increases that began in late 2024. However, NEXEN TIRE expects improved profitability in the second half as key input costs have been trending downward since early 2025.

During the first six months of 2025, the tyre maker began supplying original equipment tyres for 11 vehicle models, including the Hyundai NEXO, Kia EV4 and TASMAN, whilst deepening partnerships with global automakers, including premium brands.

The company said it would implement gradual price adjustments in the US market in response to recent tariff policy changes, focusing on expanding high-margin products and strategically reallocating global supply volumes to mitigate profitability risks.

“Despite persistent macroeconomic challenges, NEXEN TIRE achieved record-breaking sales for two consecutive quarters by maintaining balanced growth across both OE and RE segments,” said Chief Executive John Bosco (Hyeon Suk) Kim. “We will continue to reinforce our global competitiveness through strategic partnerships and region-specific initiatives.”

NEXEN TIRE has been building brand awareness through localised marketing efforts across North America, Europe, the Middle East, and the Asia-Pacific regions whilst expanding its retail presence through strategic distributor partnerships.
