Analysis
HTS 3004.31.00 covers containing insulin under heading 3004 (medicaments (excluding goods of heading 3002, 3005 or 3006) consisting of mixed or…). US Customs collects import statistics for it under 2 ten-digit suffixes, reported in kilograms.
For statistics it divides in two: 3004.31.00.10 for containing insulin glargine and 3004.31.00.90 for other. Both pay the same duty; the suffix records which kind was imported.
There is no general-rate duty on this line, which puts it with roughly 93% of the 58 tariff lines in chapter 30 that are also free. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
Goods from countries without normal trade relations pay the column 2 rate of 25% instead of nothing, so origin decides between free entry and a 25% duty.
All 17 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
The general rate of Free has not changed in any edition of the schedule since Jan 2023.
