Based on tetraethyl lead or on a mixture of tetraethyl lead and tetramethyl lead
Analysis
HTS 3811.11.10 covers based on tetraethyl lead or on a mixture of tetraethyl lead and tetramethyl lead under heading 3811 (antiknock preparations, oxidation inhibitors, gum inhibitors, viscosity improvers…).
Rates on the nearby lines range from duty-free to 6.5%. The costliest confusion would be with 3811.90.00 (antiknock preparations, oxidation inhibitors, gum inhibitors…) at 6.5%, a difference of 6.5 points on the customs value.
There is no general-rate duty on this line, which puts it with roughly 25% of the 179 tariff lines in chapter 38 that are also free. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
Goods from countries without normal trade relations pay the column 2 rate of 30% instead of nothing, so origin decides between free entry and a 30% duty.
Census statistics map these goods to NAICS 325998 (All Other Miscellaneous Chemical Product and Preparation Manufacturing), an industry of 1,319 US establishments employing 42,583 people, the industry a domestic producer of these goods reports under.
