6110.90.10

Analysis

HTS 6110.90.10 covers containing 70 percent or more by weight of silk or silk waste under heading 6110 (sweaters, pullovers, sweatshirts, waistcoats (vests) and similar articles, knitted or…). US Customs collects import statistics for it under 6 ten-digit suffixes, reported in dozens and kilograms.

Neighbouring lines carry rates from 4% to 32%, so the exact line matters. The widest gap is with 6110.30.30 (other: other), at 32%: a product that belongs there but is entered here, or the reverse, changes the duty by 31.1 percentage points.

The general duty rate is 0.9% of the customs value, which is at the low end of the rates in chapter 61 (10th percentile of 227 lines with an ad valorem rate). On a shipment valued at $10,000 that is $90 in duty before any Chapter 99 additions or preference claims.

The column 2 rate, for countries without normal trade relations, is 60%, 66.7 times the general rate.

The ten-digit suffixes separate men's or boys', women's or girls', men's or boys', women's or girls', men's or boys' and women's or girls'. The duty is the same across them; the suffix matters for statistics, licensing and some quotas, and an entry needs all ten digits.
