Wood pulp obtained by a combination of mechanical and chemical pulping processes
Analysis
HTS 4705.00.00 covers wood pulp obtained by a combination of mechanical and chemical pulping processes under heading 4705 (wood pulp obtained by a combination of mechanical and chemical pulping processes).
The normal trade relations rate here is zero, shared by about 100% of the 21 tariff lines in chapter 47, a useful check when a neighbouring dutiable line is a candidate. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
It is the only US line under subheading 4705.00, so the six-digit code used by every Harmonized System country and the eight-digit US line describe the same goods; a foreign tariff or an exporter's invoice showing 4705.00 points straight here.
Census statistics map these goods to NAICS 322110 (Pulp Mills), an industry of 35 US establishments employing 9,609 people. That concordance is how imports of this line are compared with US output.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
