Chemtall, Inc. v. United States
2016 WL 3030146
Ct. Intl. Trade2016Background
- Chemtall imported acrylamido tertiary butyl sulfonic acid (ATBS) and declared it under HTSUS subheading 2924.19.11 ("Amides," 3.7% duty).
- U.S. Customs classified ATBS under HTSUS subheading 2924.19.80 ("Other," 6.5% duty); Chemtall protested and sued in the CIT.
- The parties agreed ATBS’s chemical structure is undisputed: it contains an amide functional group with an R3 substituent that includes sulfur and oxygen (not pure hydrocarbon).
- Central legal question: whether ATBS is an "amide" (classify under 2924.19.11) or a "derivative" of an amide (classify under 2924.19.80).
- Explanatory Notes (ENs) to heading 2924 define allowable N‑substituents for amides as hydrogen, alkyl, or aryl radicals (i.e., groups composed solely of hydrogen and carbon).
- The EN to Chapter 29 treats "sulfonated derivatives" as parent compounds with H substituted by –SO3H while retaining other functional groups, supporting classification as a derivative.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether ATBS is an "amide" under HTSUS 2924.19.11 | ATBS fits the amide form because R groups may be hydrogen, hydrocarbyl, or "substituted hydrocarbyl"; expert Storey supports broader definition | "Amide" (per ENs and dictionaries) limits N‑substituents to hydrogen, alkyl, or aryl radicals (hydrocarbons only); ATBS's R3 has S and O, so not an amide | ATBS is not an "amide"; ENs and lexicographic sources limit N‑substituents to alkyl/aryl (H+C only) so ATBS falls outside 2924.19.11 |
| Whether ATBS is a "derivative" of an amide for 2924.19.80 | ATBS is not a derivative because plaintiff says "derivative" requires being produced from the parent compound by a chemical process | ENs and precedent treat "derivative" by structural relation (substitution), not manufacturing history; Chapter 29 ENs define sulfonated derivatives by H→SO3H substitution while retaining functional groups | ATBS is a sulfonated derivative of acrylamide and therefore fits 2924.19.80 |
| Proper interpretive authorities: ENs, dictionaries, expert affidavit | Plaintiff relies on expert affidavit and some textbook examples to broaden "amide" meaning | Defendant relies on ENs and multiple lexicographic/chemistry sources limiting amide substituents to alkyl/aryl; ENs carry persuasive interpretive weight | Court gives primacy to ENs and consistent lexicographic sources over plaintiff's novel expert gloss; defers to EN definition |
| Relevance of statistical suffixes under 2924.19.11 (Acrylamide) | Even if derivative, ATBS should fall under more specific statistical subheading for acrylamide derivatives | Statistical suffixes are not part of HTSUS legal text and cannot override main heading/subheading definitions | Court rejects relying on statistical suffixes; classification rests on heading/subheading/EN meaning |
