Analysis
HTS 1802.00.00 covers cocoa shells, husks, skins and other cocoa waste under heading 1802 (cocoa shells, husks, skins and other cocoa waste).
The normal trade relations rate here is zero, shared by about 16% of the 44 tariff lines in chapter 18, a useful check when a neighbouring dutiable line is a candidate. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
It is the only US line under subheading 1802.00, so the six-digit code used by every Harmonized System country and the eight-digit US line describe the same goods; a foreign tariff or an exporter's invoice showing 1802.00 points straight here.
Census statistics map these goods to NAICS 111335 (Tree Nut Farming). That concordance is how imports of this line are compared with US output.
Goods from countries without normal trade relations pay the column 2 rate of 10% instead of nothing, so origin decides between free entry and a 10% duty.
The general rate of Free has not changed in any edition of the schedule since Jan 2023.
