Analysis
Subheading 3002.90 covers other, within heading 3002. The first six digits are shared by every country that uses the Harmonized System, so this part of the code is the same in the US, UK and EU schedules; the 2 US tariff lines below it are national.
Every one of its 2 tariff lines is duty-free at the general rate, so classification within the subheading affects statistics and Chapter 99 measures rather than the base duty.
The US splits it as follows: 3002.90.10 for other: ferments (duty-free) and 3002.90.52 for other: other (duty-free).
By Census's concordance, most of its statistical lines are made by Biological Product (except Diagnostic) Manufacturing (325414). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 3002.90 once they fall within heading 3002 (human blood; animal blood prepared for therapeutic, prophylactic or diagnostic uses…). Under General Rule 6, subheadings are then compared only with others at the same level, so a product is matched against its siblings, not against lines elsewhere in the chapter.
