Analysis
HTS 2934.99.01 covers mycophenolate mofetil under heading 2934 (nucleic acids and their salts, whether or not chemically defined; other heterocyclic…).
Within this group the rate runs from duty-free to 6.5%. Compared with 2934.99.90 (other: other), which pays 6.5%, a misclassification either way moves the duty by 6.5 percentage points.
The normal trade relations rate here is zero, shared by about 26% of the 1050 tariff lines in chapter 29, a useful check when a neighbouring dutiable line is a candidate. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
Census statistics map these goods to NAICS 325412 (Pharmaceutical Preparation Manufacturing), an industry of 1,436 US establishments employing 170,029 people. That concordance is how imports of this line are compared with US output.
The general rate of Free has not changed in any edition of the schedule since Jan 2023.
