Analysis
HTS 4703.11.00 covers unbleached: coniferous under heading 4703 (chemical woodpulp, soda or sulfate, other than dissolving grades).
There is no general-rate duty on this line, which puts it with roughly 100% of the 21 tariff lines in chapter 47 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.
The other lines in the same group are 4703.19.00 (unbleached: nonconiferous, duty-free), 4703.21.00 (semibleached or bleached: coniferous, duty-free) and 4703.29.00 (semibleached or bleached: nonconiferous, duty-free).
Census statistics map these goods to NAICS 322110 (Pulp Mills), an industry of 35 US establishments employing 9,609 people, the industry a domestic producer of these goods reports under.
All 3 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
