4002

Analysis

Heading 4002 of the Harmonized Tariff Schedule covers synthetic rubber and factice derived from oils, in primary forms or in plates, sheets or strip; mixtures of any product of heading 4001 with any product of this heading, in primary forms or in plates, sheets or strip. It divides into 14 six-digit subheadings and 14 eight-digit tariff lines, with 18 ten-digit statistical suffixes below them.

Every one of its 14 tariff lines is duty-free at the general rate, so classification within the heading affects statistics and Chapter 99 measures rather than the base duty.

Its median rate of duty-free sits at the 19th percentile of the headings in chapter 40.

The largest subheadings are 4002.11 (unnamed, 1 line), 4002.19 (unnamed, 1 line), 4002.20 (unnamed, 1 line) and 4002.31 (unnamed, 1 line).

By Census's concordance, most of its statistical lines are made by Synthetic Rubber Manufacturing (325212). Those are the NAICS industries a US producer of these goods would report under.
