Petroleum resins, coumarone-indene resins, polyterpenes, polysulfides, polysulfones and other products specified in note 3 to this chapter, not elsewhere specified or included, in primary forms
Analysis
Heading 3911 of the Harmonized Tariff Schedule covers petroleum resins, coumarone-indene resins, polyterpenes, polysulfides, polysulfones and other products specified in note 3 to this chapter, not elsewhere specified or included, in primary forms. It divides into 3 six-digit subheadings and 9 eight-digit tariff lines, with 10 ten-digit statistical suffixes below them.
The spread of 6.5 percentage points between the cheapest and dearest lines makes misclassification expensive here. The highest rate, 6.5%, applies to 3911.20.00 (poly(1,3-phenylene methylphosphonate)) and 3911.90.91 (other: other).
4 of its 9 lines with a percentage rate are duty-free at the general rate (44%) and 5 are dutiable, from duty-free up to 6.5%. The median line pays 5.8%.
The largest subheadings are 3911.90 (other, 7 lines), 3911.10 (unnamed, 1 line) and 3911.20 (unnamed, 1 line).
Its median rate of 5.8% sits at the 61st percentile of the headings in chapter 39.
By Census's concordance, most of its statistical lines are made by Plastics Material and Resin Manufacturing (325211) and Synthetic Rubber Manufacturing (325212). Those are the NAICS industries a US producer of these goods would report under.
