U.S. tariffs impose 50% rates on plastic bags and closures

In July, the United States imposed a 50% tariff on polyethylene bags, stoppers, lids, caps and other tableware from Canada. About 20% of the roughly $15 billion in annual U.S.-Canada plastics trade now faces the 50% duty. There are also 15% tariffs on various molds used to make plastic, metal and rubber products.

The Section 338 duties stack on top of base tariffs and apply even to goods that qualify for free trade under the USMCA. North American polyethylene and polypropylene producers rely on ethane, which is cheaper than the naphtha used in Asia and Europe. Because of Strait of Hormuz disruptions, global demand for lower‑cost U.S. polyolefins has risen, pressuring converters that can no longer buy cheap domestic resin.

“There's people eating margin right now that make it very challenging to deliver on yearly or quarterly results,” Jim Owen, senior packaging and logistics analyst at Rabobank said.

“We spent 30 years making this a well-oiled machine with free trade on plastic and molds and resins and additives,” Jim Owen, senior packaging and logistics analyst at Rabobank said.

Fiber and metals aren’t the only packaging materials and products to get caught in the United States-Canada trade war. As companies sift through tariff codes they’re learning of the numerous plastic items that are included.
