From MFG Calcs data: Adhesives and sealants

U.S. imports of adhesives and sealants (headings 3214, 3506) came to $1.25B in 2025, with $140M in calculated duty: an effective duty of 11.3%, every duty included.

Effective duty in Sep 2026: 10.3%, against 16.1% in Sep 2025.

Largest sources in 2025: Germany $296M at 11.4% effective duty; Canada $194M at 1.6% effective duty; Mexico $154M at 0.8% effective duty; China $95.0M at 50.4% effective duty; South Korea $58.7M at 8.3% effective duty.

These are family totals from U.S. import statistics published through USITC DataWeb, not this heading's rate alone; effective duty is calculated duty as a share of customs value, an estimate, not a ruling.

About these rates

The rates are those printed in the 2026 HTS Revision 23, published by the U.S. International Trade Commission. A 10-digit statistical line takes the rates printed on the 8-digit line above it. Chapter 99 duties (Section 232, Section 301, IEEPA) depend on the product, the origin and the date, are charged on top, and are not included. A code here is a strong lead, not a ruling: confirm it with a customs broker or a CBP binding ruling.
