Copper price fluctuates at around RMB 106,000/ton in early June after peaking above RMB 110,000/ton early this year. Every RMB 1,000/ton copper hike lifts string light wiring cost by 1%~1.5%.
Aluminum price stabilizes at RMB 24,000~25,000/ton. Widening copper-aluminum price gap fuels aluminum wire & CCA as mainstream cost-down alternatives for string lights; overseas buyers actively switch to such solutions.
Rising gold & silver prices push up packaging cost; major manufacturers like MLS, Sanan Optoelectronics and CED have raised product prices by 3%~12% across chip, packaging and finished lamp segments Jan-May.
