Analysis
HTS 6107.99.50 covers containing 70 percent or more by weight of silk or silk waste under heading 6107 (men's or boys' underpants, briefs, nightshirts, pajamas, bathrobes, dressing gowns and…). US Customs collects import statistics for it under 2 ten-digit suffixes, reported in dozens and kilograms.
Within this group the rate runs from 4.8% to 14.9%. Compared with 6107.99.10 (of man-made fibers), which pays 14.9%, a misclassification either way moves the duty by 14.1 percentage points.
The general duty rate is 0.8% of the customs value, which is at the low end of the rates in chapter 61 (6th percentile of 227 lines with an ad valorem rate). On a shipment valued at $10,000 that is $80 in duty before any Chapter 99 additions or preference claims.
The column 2 rate, for countries without normal trade relations, is 60%, 75.0 times the general rate.
For statistics it divides in two: 6107.99.50.13 for sleepwear (751) and 6107.99.50.15 for other (750). Both pay the same duty; the suffix records which kind was imported.
