The UK Duty Paid mark is the government's latest weapon in the war against smuggling. It applies only to cigarettes and handrolling tobacco and not to cigars and pipe tobacco. Manufacturers are phasing it in now and are changing barcodes to make the new packs easier to identify electronically. By April 1, all packs should have it on either the tear strip or the back of packs, so after this date only buy products with the mark. All unmarked stock should be sold by the end of June, because on July 1 the new law takes effect. Display or sale of unmarked packs and pouches will be illegal from this date. If you don't comply, you risk a fine of up to £5,000 plus the possibility of a six month ban on selling tobacco products. {{FOCUS SPECIALS }}
