Hangsen Technology, located in Shenzhen, China, is a division of Hong Kong-based Hangsen Holding Co., Ltd. The company has manufactured e-liquid in facilities around the world since 2009.

Hangsen will launch SYN NIcotine—which is created with lab chemicals, rather than extracted from tobacco plants—in North America soon. Synthetic nicotine is not a new concept; other companies also manufacture tobacco-free nicotine, and it has been used commercially in a few vaping products.
