Chemtall, Inc. v. United States
878 F.3d 1012
Fed. Cir.2017Background
- Chemtall imported acrylamido tertiary butyl sulfonic acid (ATBS) in 2010–2011; Customs reclassified it from HTSUS subheading 2924.19.11 ("Amides") to 2924.19.80 ("Other"), raising the duty rate; Chemtall sued.
- Heading 2924 covers carboxyamide- and amide-function compounds; subheading 2924.19 covers "Other" acyclic amides and their derivatives and splits at the eighth-digit into "Amides" (2924.19.11) and "Other" (2924.19.80).
- Chemically, ATBS contains an amide functional group with R1 = hydrocarbyl, R2 = H, and R3 = a radical bearing heteroatoms (sulfonic acid, SO3H) bonded to the amide nitrogen.
- Central legal question: whether the HTSUS term "amide" includes compounds whose N‑attached radicals are "substituted hydrocarbyls" that contain heteroatoms (e.g., O, S), or whether "amide" is limited to N‑substituents that are H, alkyl, or aryl (hydrocarbyls).
- Court of International Trade adopted the government’s narrower definition (excluding heteroatom‑containing radicals) and held ATBS is an amide derivative classified in 2924.19.80; the Federal Circuit affirmed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Meaning of "amide" in HTSUS heading 2924 | Chemtall: "Amide" permits R groups that are hydrogen, hydrocarbyl, or "substituted hydrocarbyl" (i.e., hydrocarbyls with heteroatoms). | Government: "Amide" limited to radicals that are hydrogen, alkyl, or aryl (pure hydrocarbyls); heteroatom‑containing radicals make a compound a derivative. | Court: Adopted government definition; "amide" limited to H, alkyl, or aryl on the amide N; ATBS is a derivative, not an amide. |
| Role of HTSUS "derivative" language | Chemtall: "Derivative" should be limited to compounds chemically derived by manufacture. | Government: "Derivative" means structurally related compounds, not limited to method of manufacture. | Court: Agreed with government; "derivative" is structural and broad. |
| Interpretive weight of secondary sources and expert testimony | Chemtall: Textbooks and expert support broader definition including substituted hydrocarbyls. | Government: Authoritative texts and dictionaries support narrower definition; expert/patent definitions not controlling. | Court: Secondary sources predominantly support the narrower definition; expert testimony and patentees’ definitions were unpersuasive. |
| Proper subheading if ATBS is a derivative | Chemtall: If derivative, ATBS should still fall under ten‑digit statistical suffix 2924.19.11.50 ("Amide—Other"). | Government: Non‑amides cannot fall under an "Amides" subheading; statistical suffixes are non‑statutory and inapplicable. | Court: Rejected Chemtall’s tenth‑digit argument; statistical suffixes are not statutory and ATBS belongs in 2924.19.80. |
