HTS tariff line · chapter 28
2830.90.10
Zinc sulfide, luminescent grade having a purity of 99.99 percent or more by weight
Analysis
HTS 2830.90.10 covers zinc sulfide, luminescent grade having a purity of 99.99 percent or more by weight under heading 2830 (sulfides; polysulfides, whether or not chemically defined).
Neighbouring lines carry rates from 2.8% to 3.1%, so the exact line matters. The widest gap is with 2830.90.20 (other: cadmium sulfide), at 3.1%: a product that belongs there but is entered here, or the reverse, changes the duty by 3.1 percentage points.
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 29% of the 274 tariff lines in chapter 28. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
The other lines in the same group are 2830.90.15 (other: other zinc sulfide, 2.8%), 2830.90.20 (other: cadmium sulfide, 3.1%) and 2830.90.90 (other: other, 3%).
Census statistics map these goods to NAICS 325180 (Other Basic Inorganic Chemical Manufacturing), an industry of 705 US establishments employing 41,447 people. That is the industry code a US manufacturer of the same product would normally use.
