6902.10.10

Analysis

HTS 6902.10.10 covers containing by weight, singly or together, more than 50 percent of the elements magnesium, calcium or chromium, expressed as MgO, CaO or Cr2O3: magnesite bricks under heading 6902 (refractory bricks, blocks, tiles and similar refractory ceramic constructional goods…).

There is no general-rate duty on this line, which puts it with roughly 27% of the 82 tariff lines in chapter 69 that are also free. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.

Census statistics map these goods to NAICS 327120 (Clay Building Material and Refractories Manufacturing), an industry of 461 US establishments employing 23,500 people, the industry a domestic producer of these goods reports under.

Goods from countries without normal trade relations pay the column 2 rate of 13% instead of nothing, so origin decides between free entry and a 13% duty.

All 5 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
