Analysis
HTS 2901.22.00 covers propene (Propylene) under heading 2901 (acyclic hydrocarbons).
This line's footnotes point to one additional provision in Chapter 99: 9903.90.08 (measures on products of Russia). Chapter 99 duties are added on top of the general rate for goods of the countries they name, and they change more often than the rest of the schedule, so check the current CBP guidance before you rely on a total.
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 325110 (Petrochemical Manufacturing), an industry of 76 US establishments employing 10,888 people. That concordance is how imports of this line are compared with US output.
All 11 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
