The short answer

  • The effective U.S. tariff on rubber materials and products was 9.96% in May 2026, down from 18.04% a year earlier — calculated duties actually paid divided by customs value, from USITC data. The statutory MFN rate is Free–8% across 73 HTS lines in the 2026 schedule. Mexico is the largest source, holding 25.6% of 2025 imports.

Statutory rates from the schedule

  • Synthetic rubber, hoses, conveyor and transmission belting, and molded seals, bumpers, and O-rings — the elastomer side of every assembly. This family covers HTS headings 4002, 4009, 4010, 4016: 73 eight-digit rate lines with MFN (column 1, general) rates of Free–8% in the 2026 schedule.
  • Chapter 99 flags on individual lines mark Section 301/232 overlay provisions (e.g. 9903.88.03) that apply on top of the MFN column.
