It is now a criminal offence to sell a corrosive product to a person under the age of 18 and to deliver corrosive products to a residential address.

A residential address is classed as an address used entirely for residential purposes, so if you are operating your business from your home this is not classed as a residential address.

Deliveries and collections of corrosive products require age verification; therefore, all deliveries require someone to be there, and our delivery agents may ask for proof of ID. Deliveries will no longer be able to be left or delivered to a storage locker or garage where age verification checks cannot take place.

For collections of these, we will be implementing the Think 21 policy and therefore anyone who looks younger will be required to provide ID before the goods will be handed over. Acceptable ID includes a driver’s license, passport or PASS card.
