Imports of commodity polymers into the US in 2021 were the highest volume ever reported, 7.0 million tons, an increase of 1 million tons, 16%, from the prior year. The increase in imports, and also the drop in US exports by 15%, to 14.2 million tons, reflected strong domestic demand, US production issues and logistical problems. Demand is likely to continue strong in 2022. New US capacity and the gradual resolution of supply chain issues will likely result in further declines in imports and rising exports.
