Analysis
HTS 4704.21.00 covers semibleached or bleached: coniferous under heading 4704 (chemical woodpulp, sulfite, other than dissolving grades).
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 100% of the 21 tariff lines in chapter 47. 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 4704.11.00 (unbleached: coniferous, duty-free), 4704.19.00 (unbleached: nonconiferous, duty-free) and 4704.29.00 (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. That is the industry code a US manufacturer of the same product would normally use.
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.
