Analysis
Subheading 3920.99 covers of other plastics, within heading 3920. 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 3 US tariff lines below it are national.
None of its 3 lines is duty-free at the general rate. Rates run from 4.2% to 6% with a median of 5.8%, so the line you choose sets the duty.
The US splits it as follows: 3920.99.10 for over 0.152 mm in thickness, and not in rolls (6%), 3920.99.20 for film, strip and sheets, all the foregoing which are flexible: other (4.2%) and 3920.99.50 for of other plastics: other (5.8%).
By Census's concordance, most of its statistical lines are made by Unlaminated Plastics Film and Sheet (except Packaging) Manufacturing (326113). Those are the NAICS industries a US producer of these goods would report under.
