Analysis
HTS 3002.51.00 covers cell therapy products under heading 3002 (human blood; animal blood prepared for therapeutic, prophylactic or diagnostic uses…).
The normal trade relations rate here is zero, shared by about 93% of the 58 tariff lines in chapter 30, a useful check when a neighbouring dutiable line is a candidate. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
Census statistics map these goods to NAICS 325414 (Biological Product (except Diagnostic) Manufacturing), an industry of 441 US establishments employing 75,198 people. That concordance is how imports of this line are compared with US output.
All 10 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
The general rate of Free has not changed in any edition of the schedule since Jan 2023.
