Months of trade policy whiplash and ensuing rounds of legal challenges have created uncertainty at every stage of the supply chain, according to interviews with a half-dozen business leaders. It’s draining resources and creating logistical headaches for wholesalers, distributors and retailers during their most critical business period: June is the busiest time of year for freight, partly because companies are moving much of their inventory for back-to-school and holiday shopping.

Instead, when they’re normally focused on prepping for their most crucial business periods, import-dependent companies are slashing budgets, halting investments and looking for ways to avoid the steepest duties. Others are watching their inventories dwindle, unsure whether they’ll be able to keep shelves fully stocked. Many are cutting staff and other facets of their operations to stay afloat.
