U.S. exports of chemical preparations for photographic uses, measured or retail-packed (nesoi) (HS 370790) totaled $58.7M in July 2026.
Importers of Chemical Preparations for Photographic Uses, Measured or Retail-Packed (NESOI) paid $4.2M in duties in July 2026 — an effective duty rate of 10% on $41.2M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataJapan and South Korea are the dominant suppliers of photographic chemical preparations under this heading, reflecting the concentration of precision imaging chemistry manufacturing in East Asia. The US tariff schedule breaks out several distinct lines: Acid Violet 19 dye for photographic use (3707903100), general photographic chemical preparations (3707903290), and unmixed products in measured or retail-sale form (3707906000), each potentially carrying different Section 301 exposure depending on origin. Importers should verify classification carefully, as the distinction between a formulated preparation and an unmixed product in measured doses determines which 10-digit line applies. The Netherlands and Belgium also appear among leading suppliers, reflecting European specialty chemical producers serving the professional imaging and graphic arts markets.

A chemical preparation typically involves two or more substances combined for a specific photographic function (e.g., a developer or fixer blend), while an unmixed product in measured doses is a single chemical substance portioned for retail or end-use sale. The distinction matters because 3707906000 covers unmixed products in measured/retail form, whereas 3707903290 covers formulated preparations. When in doubt, consult a licensed customs broker or CBP ruling.
South Korea is a US free-trade-agreement partner under KORUS, so qualifying originating goods may be eligible for preferential tariff treatment. Importers must confirm that the goods meet KORUS rules of origin and provide appropriate documentation at entry.
