Japan’s Sumitomo Chemical Exits Brazilian Aluminium Refining: Focus on Business Optimization

Sumitomo Chemical

Japanese petrochemical giant, Sumitomo Chemical, has sold its 2.97% stake in Nippon Amazon Aluminium Co. (NAAC) to YKK AP, a domestic architectural goods supplier, as part of its broader business optimization strategy. With this transaction finalized on December 19, YKK AP's stake in NAAC has risen to 6.31% from 2.02%. While the financial details of the transaction were not disclosed, the move signifies a strategic shift for Sumitomo Chemical as it exits overseas aluminium refining operations.

NAAC holds a 49% stake in Aluminio Brasileiro S.A. (Albras), a Brazilian aluminium refiner renowned for producing 450,000 tons of aluminum ingots annually. Albras operates using renewable energy, making it a key player in reducing CO2 emissions in the aluminium production process. This aligns with growing global demand for sustainable and low-carbon aluminium products.

YKK AP's Green Aluminium Expansion

The deal positions YKK AP to double its aluminium ingot output, an important milestone in its efforts to procure green aluminium feedstock and decarbonize its operations. The company uses approximately 140,000 tons of aluminium annually within Japan. This acquisition is part of YKK AP's push to adopt sustainable materials and strengthen its competitiveness in the eco-conscious global market.

Sumitomo Chemical’s Broader Realignments

Sumitomo Chemical’s decision to sell its NAAC shares marks a complete withdrawal from the overseas aluminium ingot business. The company cited high profitability volatility in imported aluminium markets, largely influenced by fluctuating global aluminium prices. Earlier in the year, Sumitomo Chemical divested its shares in New Zealand Aluminium Smelters and Boyne Smelters to Rio Tinto, the UK-Australian mining conglomerate.

The company has also exited from two polypropylene (PP) compound manufacturing subsidiaries in China due to intensifying competition from local producers. Announced on December 18, this move reflects Sumitomo Chemical’s focus on optimizing its business portfolio by concentrating on more stable and profitable ventures.
