Analysis
HTS 0508.00.00 covers coral and similar materials, unworked or simply prepared but not otherwise worked; shells of molluscs, crustaceans or echinoderms and cuttlebone, unworked or… under heading 0508 (coral and similar materials, unworked or simply prepared but not otherwise worked; shells…).
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 75% of the 20 tariff lines in chapter 05. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
It is the only US line under subheading 0508.00, 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 0508.00 points straight here.
Census statistics map these goods to NAICS 114119 (Other Marine Fishing), an industry of 127 US establishments employing 238 people. That is the industry code a US manufacturer of the same product would normally use.
The general rate of Free has not changed in any edition of the schedule since Jan 2023.
