Analysis
HTS 7320.20.50 covers helical springs: other under heading 7320 (springs and leaves for springs, of iron or steel). US Customs collects import statistics for it under 4 ten-digit suffixes, reported in kilograms.
Neighbouring lines carry rates from duty-free to 3.2%, so the exact line matters. The widest gap is with 7320.90.10 (other: hairsprings), at duty-free: a product that belongs there but is entered here, or the reverse, changes the duty by 3.9 percentage points.
The general duty rate is 3.9% of the customs value, which is above most the rates in chapter 73 (87th percentile of 250 lines with an ad valorem rate). On a shipment valued at $10,000 that is $390 in duty before any Chapter 99 additions or preference claims.
Goods that qualify under GSP, the Australia FTA, the Automotive Products Trade Act, the Bahrain FTA, the Chile FTA, and 13 others can enter duty-free instead of paying 3.9%. It is also eligible under GSP, the developing-country programme, which Congress has to renew; check whether GSP is in force on the entry date.
The column 2 rate, for countries without normal trade relations, is 45%, 11.5 times the general rate.
