Power, lighting, and export consumer
Chargers and lighting fail conducted emissions and harmonics when the factory changes a PFC chip. Export brands want CISPR 32 and sometimes FCC. Domestic listings want CCC. A lab next to Ningbo port logistics is useful when the sample has to travel with a shipment, not in a courier pouch.
Zhejiang vs. Shanghai
Stay in Zhejiang when the factory and the chamber are in the same traffic pattern. Use Shanghai for a method or brand the local lab does not have. Confirm CNAS scope and whether the quote includes immunity or only emissions.
