3914.00.20
Cross-linked polyvinylbenzyltrimethylammonium chloride (Cholestyramine resin USP)
Analysis
HTS 3914.00.20 covers cross-linked polyvinylbenzyltrimethylammonium chloride (Cholestyramine resin USP) under heading 3914 (ion-exchangers based on polymers of headings 3901 to 3913, in primary forms).
Within this group the rate runs from 3.9% to 3.9%. Compared with 3914.00.60 (ion-exchangers based on polymers of headings 3901 to 3913, in primary…), which pays 3.9%, a misclassification either way moves the duty by 3.9 percentage points.
Goods from countries without normal trade relations pay the column 2 rate of 35% instead of nothing, so origin decides between free entry and a 35% duty.
The normal trade relations rate here is zero, shared by about 13% of the 236 tariff lines in chapter 39, a useful check when a neighbouring dutiable line is a candidate. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
The other line in the same group is 3914.00.60 (ion-exchangers based on polymers of headings 3901 to 3913…, 3.9%).
Census statistics map these goods to NAICS 325211 (Plastics Material and Resin Manufacturing), an industry of 1,285 US establishments employing 88,827 people. That concordance is how imports of this line are compared with US output.
