U.S. exports of borates, not elsewhere specified or included (HS 284020) totaled $3.3M in July 2026.
Importers of Borates, Not Elsewhere Specified or Included paid $132K in duties in July 2026 — an effective duty rate of 14% on $968K in dutiable value, based on actual customs collections rather than the published tariff schedule. Borates, Not Elsewhere Specified or Included imports of $1.1M in July 2026 ran 26% below the year-to-date monthly average of $1.4M.
Last updated: July 2026 dataBorates not covered by more specific headings serve a wide range of industrial end uses, including flame retardants, specialty glass, and wood preservation treatments. India leads US import supply for this residual borate category, followed by Italy and Turkey. All entries fall under a single tariff line (2840200000), so correct classification depends on confirming the compound is not a disodium tetraborate or peroxoborate, which carry their own dedicated headings.

A borate is classified here only after ruling out more specific provisions — disodium tetraborate (284011/284019) and peroxoborates (284030) each have their own headings. Compounds such as calcium borate, zinc borate, or mixed metal borates that do not fit those specific descriptions default to 2840200000.
Importers should verify current Section 301 exposure for shipments originating from China, as boron compounds from that origin have been reviewed under Section 301 lists. Consulting a licensed customs broker is advisable to confirm the applicable duty treatment at time of entry.
