Analysis
HTS 4403.91.00 covers of oak (Quercus spp.) under heading 4403 (wood in the rough, whether or not stripped of bark or sap- wood, or roughly squared). US Customs collects import statistics for it under 2 ten-digit suffixes, reported in m3.
For statistics it divides in two: 4403.91.00.20 for of red oak and 4403.91.00.40 for other. Both pay the same duty; the suffix records which kind was imported.
The normal trade relations rate here is zero, shared by about 61% of the 257 tariff lines in chapter 44, 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.
Census statistics map these goods to NAICS 113310 (Logging), an industry of 7,261 US establishments employing 42,916 people. That concordance is how imports of this line are compared with US output.
All 18 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
