Analysis

The normal trade relations rate here is zero, shared by about 27% of the 82 tariff lines in chapter 69, a useful check when a neighbouring dutiable line is a candidate. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
Goods from countries without normal trade relations pay the column 2 rate of 30% instead of nothing, so origin decides between free entry and a 30% duty.
The other line in the same group is 6904.10.00 (ceramic building bricks, flooring blocks, support or filler…, duty-free).
Census statistics map these goods to NAICS 327120 (Clay Building Material and Refractories Manufacturing), an industry of 461 US establishments employing 23,500 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.
