Largest product categories by monthly import value
HS4 headings are 4-digit codes within the Harmonized System that represent specific product categories. While HS chapters provide a broad overview, headings offer a more granular view of exactly which product types drive the largest import volumes. This page ranks headings from every chapter.
These headings cover categories like integrated circuits, motor vehicles, crude petroleum, and telecommunications equipment, which together account for a significant share of total U.S. imports. Click on any heading to explore the specific 6-digit products within it.
