Within this group the rate runs from duty-free to 5%. Compared with 4103.20.20 (vegetable pretanned), which pays 5%, a misclassification either way moves the duty by 5 percentage points.
The normal trade relations rate here is zero, shared by about 22% of the 121 tariff lines in chapter 41, a useful check when a neighbouring dutiable line is a candidate. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
Census statistics map these goods to NAICS 311611 (Animal (except Poultry) Slaughtering), an industry of 1,274 US establishments employing 159,965 people. That concordance is how imports of this line are compared with US output.
