Analysis
HTS 5007.90.30 covers containing 85 percent or more by weight of silk or silk waste under heading 5007 (woven fabrics of silk or of silk waste). US Customs collects import statistics for it under 3 ten-digit suffixes, reported in square metres and kilograms.
Neighbouring lines carry rates from duty-free to 3.9%, so the exact line matters. The widest gap is with 5007.90.60 (other fabrics: other), at 3.9%: a product that belongs there but is entered here, or the reverse, changes the duty by 3.1 percentage points.
The general duty rate is 0.8% of the customs value, which is in the middle of the rates in chapter 50 (69th percentile of 13 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 90%, 112.5 times the general rate.
The other lines in the same group are 5007.10.30 (containing 85 percent or more by weight of silk or silk…, 0.8%), 5007.10.60 (fabrics of noil silk: other, 3.9%), 5007.20.00 (woven fabrics of silk or of silk waste: other fabrics…, duty-free) and 5007.90.60 (other fabrics: other, 3.9%).
