Analysis
Subheading 3506.91 covers adhesives based on polymers of headings 3901 to 3913 or on rubber, within heading 3506. 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.
1 of its 2 lines with a percentage rate are duty-free at the general rate (50%) and 1 are dutiable, from duty-free up to 2.1%. The median line pays 1.05%.
The US splits it as follows: 3506.91.10 for optically clear free-film adhesives and optically clear curable… (duty-free) and 3506.91.50 for adhesives based on polymers of headings 3901 to 3913 or on rubber… (2.1%).
By Census's concordance, most of its statistical lines are made by Adhesive Manufacturing (325520). Those are the NAICS industries a US producer of these goods would report under.
Goods only reach 3506.91 once they fall within heading 3506 (prepared glues and other prepared adhesives, not elsewhere specified or included…). 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.
