… the toilet paper industry is split into two, largely separate markets: commercial and consumer. The pandemic has shifted the lion’s share of demand to the latter. People actually do need to buy significantly more toilet paper during the pandemic — not because they’re making more trips to the bathroom, but because they’re making more of them at home. With some 75% of the U.S. population under stay-at-home orders, Americans are no longer using the restrooms at their workplace, in schools, at restaurants, at hotels, or in airports. Georgia-Pacific, a leading toilet paper manufacturer based in Atlanta, estimates that the average household will use 40% more toilet paper than usual if all of its members are staying home around the clock. That’s a huge leap in demand for a product whose supply chain is predicated on the assumption that demand is essentially constant.
… the toilet paper made for the commercial market is a fundamentally different product from the toilet paper you buy in the store. It comes in huge rolls, too big to fit on most home dispensers. The paper itself is thinner and more utilitarian. It comes individually wrapped and is shipped on huge pallets, rather than in brightly branded packs of six or 12. “Not only is it not the same product, but it often doesn’t come from the same mills,” added Jim Luke, a professor of economics at Lansing Community College, who once worked as head of planning for a wholesale paper distributor. “So for instance, Procter & Gamble [which owns Charmin] is huge in the retail consumer market. But it doesn’t play in the institutional market at all.”
