Analysis
HTS 4409.29.11 covers other: wood siding under heading 4409 (wood (including strips and friezes for parquet flooring, not assembled) continuously…).
Neighbouring lines carry rates from duty-free to 4.9%, so the exact line matters. The widest gap is with 4409.29.66 (sanded, grooved or otherwise advanced in condition), at 4.9%: a product that belongs there but is entered here, or the reverse, changes the duty by 4.9 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 321113 (Sawmills), an industry of 2,691 US establishments employing 79,871 people. That is the industry code a US manufacturer of the same product would normally use.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
