Factories in the U.S. are churning through their inventories, as logistical problems keep some manufacturers from restocking rapidly enough to keep up with rising demand.
American factories’ sales rose 8% in September from the prior year, while their inventories grew just 5% during the same period, according to fresh data from the Commerce Department.

U.S. economic output rose in the second and third quarters at the fastest annual rates in nearly four years, fueling robust demand for manufactured products. Global economic growth also helped propel sales of American-made goods, though some of the world’s major economies have showed signs of slowing in the third quarter.
Jake McRobie, U.S. economist at Oxford Economics, said he views the new Commerce data as signaling “a return to normal, healthy levels of inventories.”
However, a truck-driver shortage in the U.S. has delayed shipments and pushed up delivery costs, making it difficult for some factory owners to keep themselves comfortably stocked.
At the same time, the Trump administration’s early 2018 tariffs and countertariffs by foreign countries are putting pressure on inventories of some products. The administration has imposed tariffs on half the $500 billion in Chinese goods imported annually, and on steel and aluminum from around the world, while threatening to do the same on cars.
This has caused purchasers of affected products to step up their orders to try to get ahead of price increases, drawing on inventories.
“The tariffs have caused a mass rush to buy up inventories of affected products in order to minimize the long-term financial impact,” a computer and electronic products manufacturer told the Institute for Supply Management. “This, in turn, is causing market constraints, which further drive up the cost and increase lead times.”
ISM’s latest manufacturing report showed the fabricated metal products and primary metals industry both reported inventory declines in October. The report also showed inventory declines in other industries such as paper products, signaling the churn is more widespread.
Additionally, Tim Fiore, head of the ISM survey, said manufacturers’ inventories often fall as they close a quarter, which could explain part of September’s decline.
Determining whether inventories are at a healthy level is tricky. A high level of inventories can imply factory owners are ramping up production as they anticipate rising demand for their products, or it can mean demand unexpectedly flagged.
Some factory owners are responding to the disruptions. Manufacturers in the Cleveland area reported they have “increased their capital expenditures to keep up with customer demand and to fill supply chain gaps,” according to a report released by the Federal Reserve late last month.
