4002.70.00

Analysis

HTS 4002.70.00 covers ethylene-propylene-nonconjugated diene rubber (EPDM) under heading 4002 (synthetic rubber and factice derived from oils, in primary forms or in plates, sheets or…).

There is no general-rate duty on this line, which puts it with roughly 39% of the 142 tariff lines in chapter 40 that are also free. Duty-free at the general rate does not rule out additional duties under Chapter 99, such as Section 301 or Section 232 measures, which depend on the country of origin.

Goods from countries without normal trade relations pay the column 2 rate of 20% instead of nothing, so origin decides between free entry and a 20% duty.

Census statistics map these goods to NAICS 325212 (Synthetic Rubber Manufacturing), an industry of 153 US establishments employing 11,337 people, the industry a domestic producer of these goods reports under.

All 13 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.
