U.S. exports of acrylic polymers (other), primary forms (HS 390690) totaled $147.8M in August 2026.
Importers of Acrylic Polymers (Other), Primary Forms paid $9.6M in duties in August 2026, an effective tariff rate of 10.52% of the $91.3M imported — duty actually collected as a share of that value, not the published tariff schedule.
Last updated: August 2026 dataAcrylic polymers not elsewhere specified—spanning elastomeric grades (3906901000), plastic grades (3906902000), and two residual NESOI lines (3906905000, 3906906000)—serve as key intermediates in adhesives, coatings, superabsorbent materials, and textile finishing. Japan leads US import supply, with Canada and Germany also significant sources, reflecting the concentration of specialty polymer production in advanced manufacturing economies. Importers should note that several acrylic polymer lines from certain origins may be subject to Section 301 tariffs, making origin documentation and tariff classification precision especially important. The elastomeric versus plastic distinction at the 10-digit level drives duty treatment and end-use qualification.

The elastomeric designation applies when the polymer exhibits rubber-like elastic recovery at room temperature; plastic grades do not. Technical data sheets showing elongation, recovery, and glass transition temperature are typically used to support the classification. When the product falls into neither category, the NESOI lines (3906905000 or 3906906000) apply. Consulting a licensed customs broker with the product's technical specification is advisable.
Imports from certain origins—particularly from China—may be subject to Section 301 tariffs. Because the applicable measure and rate depend on both the specific 10-digit HTS line and the country of origin, importers should verify current Section 301 lists and any applicable exclusions before entry.
