Adhesives and Sealants: Statutory & Effective Tariff Rates

USITC Column 1 General rates for 8 adhesives and sealants HTS lines (parseable range 0%–6.5%). Effective rate Jun 2026: 10.57%; monthly history since 2020.

The short answer

The observed effective calculated-duty rate on U.S. imports of adhesives and sealants was 10.57% in Jun 2026, down from 11.63% a year earlier — USITC Calculated Duties divided by covered customs value. The Column 1 General line-rate range is 0%–6.5% across 8 HTS lines in the 2026 schedule; individual lines are called “Free” only when the official General field is literally Free, which still does not determine a shipment’s final duty. Germany is the largest source, holding 23.7% of 2025 imports.

Statutory rates from the schedule

Structural adhesives, prepared glues, caulks, and mastics — bonding and sealing where fasteners and welds do not reach. This family covers HTS headings 3214, 3506: 8 eight-digit rate lines with a parseable Column 1 General range of 0%–6.5% in the 2026 schedule. “Free” means the official General field is literally Free for that line; it does not determine final entry liability.
Chapter 99 references on individual lines (for example, 9903.90.08) identify provisions to review; applicability and any additional duty depend on the entry facts.
