The business or occupation of a chandler; the manufacture and sale of candles and ship supplies.
From chandler (one who makes/sells candles) + -ing (noun suffix). This gerund form emphasizes the activity and business aspect of chandlery work.
Chandlering was actually a quite sophisticated business—a chandler needed to know chemistry (how to render tallow, make wax work), maritime logistics, and retail—it wasn't just craft but serious commerce.
