6806.20.00

Analysis

HTS 6806.20.00 covers exfoliated vermiculite, expanded clays, foamed slag and similar expanded mineral materials (including intermixtures thereof) under heading 6806 (slag wool, rock wool and similar mineral wools; exfoliated vermiculite, expanded clays…).

This line's footnotes point to one additional provision in Chapter 99: 9903.90.08 (measures on products of Russia). Chapter 99 duties are added on top of the general rate for goods of the countries they name, and they change more often than the rest of the schedule, so check the current CBP guidance before you rely on a total.

Neighbouring lines carry rates from duty-free to 3.9%, so the exact line matters. The widest gap is with 6806.10.00 (slag wool, rock wool and similar mineral wools (including…), at 3.9%: a product that belongs there but is entered here, or the reverse, changes the duty by 3.9 percentage points.

Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 60% of the 67 tariff lines in chapter 68. Duty-free at the general rate does not rule out additional duties under Chapter 99, such as Section 301 or Section 232 measures, which depend on the country of origin.

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.
