Analysis
HTS 4409.29.51 covers wood moldings: other under heading 4409 (wood (including strips and friezes for parquet flooring, not assembled) continuously…).
Within this group the rate runs from duty-free to 4.9%. Compared with 4409.29.66 (sanded, grooved or otherwise advanced in condition), which pays 4.9%, a misclassification either way moves the duty by 4.9 percentage points.
Goods from countries without normal trade relations pay the column 2 rate of 40% instead of nothing, so origin decides between free entry and a 40% duty.
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 321918 (Other Millwork (including Flooring)), an industry of 1,445 US establishments employing 32,379 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.
