Analysis
HTS 4421.91.10 covers wood dowel pins: plain under heading 4421 (other articles of wood).
Rates on the nearby lines range from duty-free to 10.7%. The costliest confusion would be with 4421.91.30 (consisting of wooden frames in the center of which are fixed louver…) at 10.7%, a difference of 10.7 points on the customs value.
There is no general-rate duty on this line, which puts it with roughly 61% of the 257 tariff lines in chapter 44 that are also free. 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 321999 (All Other Miscellaneous Wood Product Manufacturing), an industry of 2,327 US establishments employing 31,381 people, the industry a domestic producer of these goods reports under.
Goods from countries without normal trade relations pay the column 2 rate of 5% instead of nothing, so origin decides between free entry and a 5% duty.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
