6806.10.00

Slag wool, rock wool and similar mineral wools (including intermixtures thereof), in bulk, sheets or rolls

Analysis

HTS 6806.10.00 covers slag wool, rock wool and similar mineral wools (including intermixtures thereof), in bulk, sheets or rolls under heading 6806 (slag wool, rock wool and similar mineral wools; exfoliated vermiculite, expanded clays…). US Customs collects import statistics for it under 5 ten-digit suffixes, reported in square metres.

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.

Within this group the rate runs from duty-free to duty-free. Compared with 6806.90.00 (slag wool, rock wool and similar mineral wools; exfoliated…), which pays duty-free, a misclassification either way moves the duty by 3.9 percentage points.

The general duty rate is 3.9% of the customs value, which is above most the rates in chapter 68 (79th percentile of 67 lines with an ad valorem rate). On a shipment valued at $10,000 that is $390 in duty before any Chapter 99 additions or preference claims.

Goods that qualify under GSP, the Australia FTA, the Bahrain FTA, the Chile FTA, the Colombia TPA, and 12 others can enter duty-free instead of paying 3.9%. It is also eligible under GSP, the developing-country programme, which Congress has to renew; check whether GSP is in force on the entry date.

The column 2 rate, for countries without normal trade relations, is 30%, 7.7 times the general rate.
