5505.10.00

Analysis

HTS 5505.10.00 covers of synthetic fibers under heading 5505 (waste (including noils, yarn waste and garnetted stock) of man-made fibers). US Customs collects import statistics for it under 3 ten-digit suffixes, reported in kilograms.

Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 7% of the 133 tariff lines in chapter 55. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.

The other line in the same group is 5505.20.00 (of artificial fibers, duty-free).

Census statistics map these goods to NAICS 325220 (Artificial and Synthetic Fibers and Filaments Manufacturing), an industry of 129 US establishments employing 13,925 people. That is the industry code a US manufacturer of the same product would normally use.

The ten-digit suffixes separate of nylon or other polyamides and of polyesters. The duty is the same across them; the suffix matters for statistics, licensing and some quotas, and an entry needs all ten digits.

Goods from countries without normal trade relations pay the column 2 rate of 10% instead of nothing, so origin decides between free entry and a 10% duty.
