Things like toilet roll are made from pulp which is mostly imported.
"One of the UK's major toilet tissue importers has been stockpiling to ensure it can maintain supplies in the event of a no-deal Brexit."
"German-owned Wepa has stockpiled an extra 600 tonnes of finished product, or about 3.5m rolls, in UK warehouses."
"UK boss Mike Docker said Wepa was now chartering ships to import materials, rather than use trucks."
"Wepa in the UK is based in Bolton, and has a production site in Bridgend, in South Wales. It has taken on an extra 60,000 square feet of warehousing space for stockpiling."
"In addition to the finished product, it has also shipped in extra cardboard and tissue."
"Wepa sells toilet paper and kitchen roll which used by retailers for their own-brand products.Customers include Lidl, Morrisons, Sainsbury's, and Tesco."
"When the firm starting preparing its so-called "Brexit buster" plan, it looked at the worst-case scenario - leaving without a deal - and prepared for that, Mr Docker said."
"It was planning to start shipping tissue from a supplier in Naples, rather than using trucks, as that was felt to be more environmentally friendly, and to cut down on paperwork."
"Brexit made the firm accelerate those plans, he said."
