AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
A walk-behind plate compactor is operator-guided but not self-propelled in the mechanical sense, so it generally classifies under 843061 (8430610000). However, if the unit has an integrated engine that drives forward movement as well as compaction, the self-propelled test must be applied carefully. Consulting a licensed customs broker is advisable for borderline units.
