7101

Analysis

Heading 7101 of the Harmonized Tariff Schedule covers pearls, natural or cultured, whether or not worked or graded but not strung, mounted or set; pearls, natural or cultured, temporarily strung for convenience of transport. It divides into 3 six-digit subheadings and 5 eight-digit tariff lines, with 5 ten-digit statistical suffixes below them.

Every one of its 5 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 23rd percentile of the headings in chapter 71.

The largest subheadings are 7101.10 (natural pearls, 2 lines), 7101.22 (worked, 2 lines) and 7101.21 (unnamed, 1 line).

By Census's concordance, most of its statistical lines are made by Jewelry and Silverware Manufacturing (339910) and Other Marine Fishing (114119). Those are the NAICS industries a US producer of these goods would report under.
