Acid violet 19

HTS code 3707.90.31.00 classifies imports of: Acid violet 19. This line sits within Chapter 37 (Photographic plates and film in the flat, sensitized, unexposed, of any material other than paper, paperboard or textiles; instant print film in the flat, sensitized, unexposed, whether or not in packs:), Section VI (Products of the Chemical or Allied Industries), and is catalogued as a tariff line in the USITC 2026 Basic Edition. Duty is calculated against units of quantity: kg. Getting the classification right is the single most important step in import compliance — a wrong code can mean overpayment of duty, shipment delays, or penalties at the border.

The general (MFN / Column 1 General) rate for HTS 3707.90.31.00 is Free, which applies to most trading partners of the United States. No special preferential rate is listed for this line, so FTA origin alone will not reduce the general duty. The Column 2 rate of 15.4¢/kg + 50% applies to imports from non-MFN countries such as Cuba and North Korea — a much higher historical "full" tariff. Because the general rate is Free, most imports under this code enter the US without duty, though anti-dumping, countervailing, or Section 301 tariffs can still apply depending on country of origin.

Beyond the published rate, importers should check for Section 201 safeguards, Section 301 China tariffs, and any active AD/CVD orders that can materially change the real landed cost.
