Granulated slag (slag sand) from the manufacture of iron or steel
Analysis
HTS 2618.00.00 covers granulated slag (slag sand) from the manufacture of iron or steel under heading 2618 (granulated slag (slag sand) from the manufacture of iron or steel).
The normal trade relations rate here is zero, shared by about 97% of the 39 tariff lines in chapter 26, a useful check when a neighbouring dutiable line is a candidate. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
It is the only US line under subheading 2618.00, so the six-digit code used by every Harmonized System country and the eight-digit US line describe the same goods; a foreign tariff or an exporter's invoice showing 2618.00 points straight here.
Census statistics map these goods to NAICS 331110 (Iron and Steel Mills and Ferroalloy Manufacturing), an industry of 359 US establishments employing 78,532 people. That concordance is how imports of this line are compared with US output.
Goods from countries without normal trade relations pay the column 2 rate of 10% instead of nothing, so origin decides between free entry and a 10% duty.
