Metal dealing is defined as carrying out a business consisting partly or wholly of the buying and selling of used or partly manufactured metal.
Businesses which buy metal to manufacture other articles do not require a metal dealing licence, even if metal is sold as a bi-product or where surplus to requirements.
A particular licence - known as an "itinerant metal dealer's licence" - is required where someone travels from place to place buying and selling metal without storing it at specific premises.
An itinerant metal dealer's licence has less onerous requirements attached to it - but records of purchases and sales must still be kept.
Where someone carries out a business as both a metal dealer and an itinerant metal dealer, both types of licence are required.
