3006.30

Analysis

Subheading 3006.30 covers opacifying preparations for X-ray examinations; diagnostic reagents designed to be administered to the patient, within heading 3006. 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: 3006.30.10 for containing antigens or antisera (duty-free) and 3006.30.50 for opacifying preparations for X-ray examinations; diagnostic reagents… (duty-free).

By Census's concordance, most of its statistical lines are made by In-Vitro Diagnostic Substance Manufacturing (325413). Those are the NAICS industries a US producer of these goods would report under.

Goods only reach 3006.30 once they fall within heading 3006 (pharmaceutical goods specified in note 4 to this chapter). 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.
