Analysis
HTS 7307.21.50 covers flanges: other under heading 7307 (tube or pipe fittings (for example, couplings, elbows, sleeves), of iron or steel).
Within this group the rate runs from duty-free to 6.2%. Compared with 7307.92.30 (sleeves (couplings)), which pays duty-free, a misclassification either way moves the duty by 5.6 percentage points.
The general duty rate is 5.6% of the customs value, which is among the highest the rates in chapter 73 (93rd percentile of 250 lines with an ad valorem rate). On a shipment valued at $10,000 that is $560 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 5.6%. 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%, 8.0 times the general rate.
Census statistics map these goods to NAICS 332919 (Other Metal Valve and Pipe Fitting Manufacturing), an industry of 212 US establishments employing 13,428 people. That concordance is how imports of this line are compared with US output.
