Costco Wholesale COST.O

U.S. retailer Costco's contingency plans include pre-shipping some products to get in holiday goods early and preparing to use different ports, Costco's CEO Ron Vachris said last week.

The Danish shipping and logistics giant said in August that should a general work stoppage occur on the U.S. Gulf and East Coasts, even a one-week shutdown could take 4-6 weeks to recover from, "with significant backlogs and delays compounding with each passing day."

"We have been working on contingency plans with customers for months, helping them import freight early and diversify freight to other ports," Mia Ginter, director of North American shipping, told Reuters. A significant volume shift to the West Coast could challenge rail services, requiring more use of truck and transload services, Ginter added.

Maher Terminals and APM Terminals

Maher and Maersk's APM, which are members of the employer negotiating group (USMX), said they were keeping their terminals at the Port of New York and New Jersey open for two additional hours to clear cargo before the potential strike.

Garden City Terminal and Norfolk International Terminal

The Garden City Terminal at the Port of Savannah and the Norfolk International Terminal at the Port of Virginia have also extended their gate hours for the weekend before Sept. 30 to clear cargo.

The shipping giant has said it is closely monitoring the strike situation and will keep customers involved as developments unfold.

Andreas Stihl AG & Co

The German chainsaw manufacturer Andreas Stihl AG & Co told Reuters it is also developing contingency plans to keep exports flowing from its factory near the Port of Virginia, but didn't elaborate. Stihl's U.S. plant ships products to over 80 countries.

Designer Brands DBI.N

Ronnie Robinson, chief supply chain officer at DSW parent company Designer Brands, said the company has shifted half of its usual imports through the East Coast to the West Coast. Robinson added that his company cannot risk late deliveries to clients like Macy's M.N, Nordstrom JWN.N, and Dillard's DDS.N department stores, even if it means paying more for shipments.

National Association of Manufacturers

NAM CEO Jay Timmons said a strike would throw manufacturing supply chains throughout the U.S. into disarray. "Billions of dollars of goods - from food to vehicles to electronics - rely on access to the East and Gulf Coast ports," Timmons said on Monday.
