Analysis
HTS 3905.99.30 covers polyvinyl carbazole (including adjuvants) under heading 3905 (polymers of vinyl acetate or of other vinyl esters, in primary forms; other vinyl…).
Rates on the nearby lines range from 3.2% to 5.3%. The costliest confusion would be with 3905.99.80 (other: other) at 5.3%, a difference of 5.3 points on the customs value.
Goods from countries without normal trade relations pay the column 2 rate of 43.5% instead of nothing, so origin decides between free entry and a 43.5% duty.
There is no general-rate duty on this line, which puts it with roughly 13% of the 236 tariff lines in chapter 39 that are also free. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
Census statistics map these goods to NAICS 325211 (Plastics Material and Resin Manufacturing), an industry of 1,285 US establishments employing 88,827 people, the industry a domestic producer of these goods reports under.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
