Analysis
HTS 4418.73.20 covers having a face ply more than 6 mm in thickness under heading 4418 (builders' joinery and carpentry of wood, including cellular wood panels and assembled…).
Neighbouring lines carry rates from duty-free to 8%, so the exact line matters. The widest gap is with 4418.73.30 (other: other), at 8%: a product that belongs there but is entered here, or the reverse, changes the duty by 8 percentage points.
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 61% of the 257 tariff lines in chapter 44. 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 321918 (Other Millwork (including Flooring)), an industry of 1,445 US establishments employing 32,379 people. That is the industry code a US manufacturer of the same product would normally use.
The general rate of Free has not changed in any edition of the schedule since Jan 2023.
