Goods from countries without normal trade relations pay the column 2 rate of 30.5% instead of nothing, so origin decides between free entry and a 30.5% duty.
There is no general-rate duty on this line, which puts it with roughly 26% of the 1050 tariff lines in chapter 29 that are also free. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
Census statistics map these goods to NAICS 325199 (All Other Basic Organic Chemical Manufacturing), an industry of 894 US establishments employing 77,304 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.
