As online shopping continues to increase, so, too, are product returns. To help meet this rising demand for reverse logistics, transportation providers are adding services to simplify product returns for shippers and consumers while also increasing efficiency.

Procter & Gamble Co., the maker of Bounty paper towels, Crest toothpaste and Pampers diapers, says the cost of trucking its goods is still on the rise. Whether that leads to more price increases for U.S. consumers on top of last year’s remains to be seen.

While the growth of e-commerce is widely viewed as a boon for last-mile deliveries, customer returns of the merchandise that’s delivered also are forcing change across carriers’ and shippers’ supply chains, industry experts said.

Intermodal rail and trucking companies are competing to meet the transportation needs of e-commerce businesses while adapting to how these new supply chains differ from those of traditional brick-and-mortar retailers.
