Restraint/Challenge

“Fluctuations in raw material availability ”

• The production of busways depends heavily on key materials such as copper, aluminum, steel, and specialized insulation, which are often subject to price volatility and supply chain disruptions. Variability in the availability of these raw materials can lead to higher production costs, manufacturing delays, and limited supply, affecting the timely delivery of busway systems to customers. This creates challenges for manufacturers trying to meet growing demand, particularly in regions experiencing significant infrastructure development and industrial expansion.
• Fluctuations in raw material prices can also reduce the competitiveness of busway solutions compared to alternative power distribution systems. Significant increases in material costs may force manufacturers to raise busway prices, making them less cost-effective for certain consumers and potentially limiting adoption in price-sensitive markets. To mitigate these challenges, companies in the busway market need to diversify suppliers, optimize production processes, and explore alternative materials to stabilize costs and maintain market competitiveness.
• Recent examples underscore the impact of raw material fluctuations on the busway market. In October 2024, aluminum prices on the London Metal Exchange rose by 1.8% to USD 2,640 per metric ton due to high alumina costs and rising demand from China, illustrating supply chain vulnerabilities. Similarly, in November 2024, copper prices fluctuated amid shortages of secondary copper and customs delays at Port Klang West in Malaysia, which were projected to reduce exports by 20%-40%. Such fluctuations increase production costs and create supply uncertainties, emphasizing the need for strategic management of raw material supply to ensure the stability and long-term growth of the busway market.
