In 2025, hexamethylenediamine imports into the United States are subject to multiple layers of tariffs that cumulatively reshape cost structures and sourcing decisions. At the federal level, the Harmonized Tariff Schedule designates HS code 2921.22 for hexamethylenediamine and its salts, with a base duty rate of 6.5 percent ad valorem on most non-FTA imports. On top of this, a special additional duty of 46 percent plus a fixed charge of 15.4 cents per kilogram applies to shipments from designated producing countries, amplifying landed costs significantly.

Moreover, Section 301 measures remain in effect for certain chemical imports originating from China, imposing an extra 25 percent ad valorem tariff on top of existing rates. These supplementary duties stem from investigations into unfair trade practices and have been maintained through recent administrative reviews. The aggregate impact of combined ad valorem and per-unit charges has incentivized buyers to seek regional alternatives and to invest in domestic or near-shore production capacity.

Complementing these measures, U.S. customs enforcement and exclusion processes under the Section 301 framework require importers to verify HTS subheadings and pursue case-by-case duty relief petitions. Enterprises navigating this environment must dedicate resources to classify shipments accurately, secure potential exclusions and maintain compliance with evolving policy determinations.

Segmentation analysis reveals application insights where polyamide intermediates command commanding share, driven by nylon synthesis that spans fiber, film and resin output.
