RE: The tariff classification of Calcium Green-1, Hexapotassium Salt (C-3010) (CAS 154719-40-1); Calcium Green-1, AM (C-3012) (CAS 186501-28-0); Calcium Green-2, AM (C-3732) (CAS 163634-11-5); Calcium Green-2, Octapotassium Salt (C-3730) (CAS 170516-40-2); and Calcium Green-5N, AM (C-3739) (CAS 216699-33-1) from Denmark.

Dear Mr. Bale:

In your letter dated June 15, 2000, you requested a tariff classification ruling for the following products which you have stated are fluorescent indicators that exhibit a spectral response upon the binding of calcium ions:

Calcium Green-1, Hexapotassium Salt (C-3010) Chemical Name - N-(2-(2-(2-(bis(carboxymethyl)amino)-5-((2',7'-dichloro-3',6'-dihydroxy-3-oxospiro[isobenzofuran-1(3H),9'-(9H)xanthen)-5-YL)carbonyl)amino) phenoxy)ethoxy)phenyl)-N-(carboxymethyl)glycine, hexapotassium salt.

Calcium Green-1, AM (C-3012)
Chemical Name - N-(2-((acetoxy)methoxy)-2-oxoethyl)-N-(2-(2-(5-(((3',6'-bis(acetyloxy)-2',7'-dichloro-3-oxospiro(isobenzofuran-1(3H),9'-(9H)xanthen)-5-YL)carbonyl)amino)-2-(bis(2-((acetyloxy)methoxy)-2-oxoethyl)amino)phenoxy)ethoxy)phenyl)glycine, (acetyloxy)methyl ester.

Calcium Green-2, AM (C-3732)
Chemical Name - N,N'-(1,2-ethanediylbis[oxy(4-(((3',6'-bis(acetyloxy)-2',7'-dichloro-3-oxospiro[isobenzofuran-1-(3H),9'-(9H)xanthen)-5-YL)carbonyl)amino)-2,1-phenylene)))bis(N-(2-((acetyloxy)methoxy)-2-oxoethyl]glycine,bis((acetyloxy)methyl) ester.

Calcium Green-2, Octapotassium Salt (C-3730) Chemical Name - N,N'-(1,2-ethanediylbis(oxy(4-((2',7'-dichloro-3',6'-dihydroxy-3-oxospiro(isobenzofuran-1(3H),9'-(9H)xanthen)-5-YL)carbonyl)amino)-2,1-phenylene)))bis[N-(carboxymethyl)glycine, octapotassium salt.

Calcium Green-5N, AM (C-3739)
Chemical Name - N-(2-((acetyloxy)methoxy)-2-oxoethyl)-N-(4-(((3',6'-bis(acetyloxy)-2',7'-dichloro-3-oxospiro(isobenzofuran-1(3H),9'-(9H)xanthen)-5-YL)carbonyl)amino)-2-(2-(2-(bis(2-((acetyloxy)methoxy)-2-oxoethyl)amino)-5-nitrophenoxy)ethoxy)phenyl) glycine,(acetoxy)methyl ester.

The applicable subheading will be 2932.99.6000, Harmonized Tariff Schedule of the United States (HTS), which provides for heterocyclic compounds with oxygen hetero-atom(s) only: other. The rate of duty will be 9.3 percent ad valorem.
