Carboxylic acids with alcohol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives: tartaric acid
Analysis
HTS 2918.12.00 covers carboxylic acids with alcohol function but without other oxygen function, their anhydrides, halides, peroxides, peroxyacids and their derivatives: tartaric acid under heading 2918 (carboxylic acids with additional oxygen function and their anhydrides, halides, peroxides…).
Within this group the rate runs from duty-free to 6.5%. Compared with 2918.29.75 (other: other), which pays 6.5%, a misclassification either way moves the duty by 6.5 percentage points.
The normal trade relations rate here is zero, shared by about 26% of the 1050 tariff lines in chapter 29, 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.
Census statistics map these goods to NAICS 325199 (All Other Basic Organic Chemical Manufacturing), an industry of 894 US establishments employing 77,304 people. 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 17% instead of nothing, so origin decides between free entry and a 17% duty.
