Details
Melatonin's regulatory status varies significantly by country. In the European Union, Australia, and the UK, melatonin is classified as a prescription medicine and cannot be freely imported as a supplement. Canada treats it as a natural health produc. In the reverse direction (taking melatonin out of New Zealand): allowed — Melatonin supplements may be exported from New Zealand freely as a dietary supplement. Arrival inspections are conducted by New Zealand Customs Service (NZCS); when in doubt, use the declare (red) channel — declared goods at worst attract duty or surrender, while undeclared goods attract penalties.
