U.S. imports of esters of other inorganic acids (non-phosphorus), nesoi (HS 292090) totaled $37.1M in July 2026, traded with 21 countries.
Importers of Esters of Other Inorganic Acids (Non-Phosphorus), NESOI paid $2.1M in duties in July 2026 — an effective duty rate of 6.6% on $31.2M in dutiable value, based on actual customs collections rather than the published tariff schedule. Esters of Other Inorganic Acids (Non-Phosphorus), NESOI imports of $37.1M in July 2026 ran 41% above the year-to-date monthly average of $26.4M.
Last updated: July 2026 dataEsters derived from inorganic acids other than phosphoric or phosphorous acid — including sulfuric, nitric, and other nonmetal inorganic acid esters — are captured here when not more specifically provided for elsewhere. The US schedule subdivides this residual heading into aromatic pesticide esters (2920901000), other aromatic esters (2920902000), non-aromatic esters of nonmetal inorganic acids (2920905100), and a general NESOI line (2920900002). China is the leading supplier, followed by France and South Korea, and Chinese-origin material may be subject to Section 301 tariffs depending on the specific compound.

The key distinctions are aromatic vs. non-aromatic structure and pesticide vs. non-pesticide end use. Aromatic esters used as pesticides go to 2920901000; other aromatic esters to 2920902000; non-aromatic esters of nonmetal inorganic acids to 2920905100; and remaining compounds to the general NESOI line 2920900002. A licensed customs broker or chemist familiar with HTS nomenclature should review the molecular structure and intended use.
Classification into the pesticide-designated line (2920901000) depends on whether the aromatic ester functions as a pesticidal active ingredient or is imported primarily for that application. General-purpose aromatic esters used as industrial intermediates, solvents, or non-pesticidal reagents would fall under 2920902000. End-use documentation and product labeling are key evidence in making this determination.
