US imports were $899.9M in the 12 months to Aug 2026, up 2.8% on the 12 months to Aug 2018. US exports were $38.9M, down 80%. In January 2022 the HS 2022 revision moved some goods between this code and 4418.81, 4418.82, 4418.83 and 2 more, so part of a change across the dashed line can be the revision. This code began with the HS 2017 revision in January 2017, taking goods from 4418.90, so its history starts there.
