9011.10

Analysis

Subheading 9011.10 covers stereoscopic microscopes, within heading 9011. 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: 9011.10.40 for provided with a means for photographing the image (duty-free) and 9011.10.80 for stereoscopic microscopes: other (duty-free).

By Census's concordance, most of its statistical lines are made by Commercial and Service Industry Machinery Manufacturing (33331). Those are the NAICS industries a US producer of these goods would report under.

Goods only reach 9011.10 once they fall within heading 9011 (compound optical microscopes, including those for photomicrography, cinemicrography or…). 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.
