U.S. imports of Honing or Lapping Machines for Metalworking (SITC 73167) totaled $2.3M in August 2026, imported from 19 countries.
Importers of Honing or Lapping Machines for Metalworking paid $289K in duties in August 2026, an average duty rate of 12.36% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataHoning and lapping machines achieve surface finishes and dimensional tolerances beyond what conventional grinding can deliver, making them indispensable in engine cylinder bore finishing, hydraulic component manufacturing, and precision bearing production. Honing uses abrasive stones in a controlled reciprocating motion; lapping uses loose abrasive slurry between a lap and workpiece — two distinct processes that nonetheless share this SITC heading. Both machine types are widely traded as capital goods for automotive, aerospace, and fluid-power industries, and their classification is generally straightforward provided the machine's abrasive finishing function is clearly documented.

27 import shipments a month
Honing machines use bonded abrasive stones that simultaneously rotate and reciprocate against the workpiece bore, removing very small amounts of material to correct geometry and improve surface finish. Grinding machines use a high-speed rotating wheel as the primary cutting element. The motion pattern, abrasive form (stones vs. wheel), and material removal rate are the key distinguishing factors CBP considers.
No special import permits are required for these machine tools. However, large capital equipment shipments may require formal entry regardless of value, and machinery imported for a specific manufacturing project may qualify for temporary importation under bond (TIB) if it will be re-exported. Importers should also confirm whether the machine's origin triggers any Section 301 tariff liability.
