Products classified under HTS 9817.29.01
4-Amino-N-ethyl-N-(2-methoxyethyl)-2-methylbenzene sulfonamide
This aromatic amine compound serves as a key intermediate in the synthesis of photographic color couplers used in color film development. Its cyclic aromatic structure with sulfonamide functionality makes it essential for creating magenta coupler precursors. Classified under chapter 29 as a substituted benzene derivative specifically for photographic chemical manufacturing.
2-Chloro-5-nitroaniline
A nitro-substituted chloroaniline used as an intermediate in manufacturing yellow photographic color couplers. The aromatic ring structure provides the foundation for chromophore development in color film emulsions. Duty-free when proven for exclusive use in photographic coupler production.
N-(2-Cyanoethyl)-4-methoxy-2-nitroaniline
Cyanoethylated nitroaniline derivative serving as a precursor for cyan dye-forming couplers in color negative films. Its modified aromatic structure enables specific color coupling reactions during photographic processing. Qualifies for duty-free import when designated for photographic chemical manufacture.
1-Hydroxy-N-(2-methylphenyl)-2-naphthamide
Naphthol-based amide coupler intermediate for magenta dye formation in color films. The fused aromatic ring system provides the characteristic color development properties required for photographic applications. Specifically qualifies under 9817.29.01 for duty-free entry in coupler manufacturing.
Acetoacet-2-methoxy-4-chloroanilide
Beta-ketoanilide compound used in yellow coupler synthesis for color reversal films. The activated methylene group facilitates dye coupling reactions with oxidized color developers. Aromatic structure qualifies for duty-free import under photographic chemical provisions.
2,4-Dichloro-3-methylphenol
Chlorinated phenolic intermediate for developing magenta couplers in color print films. Provides necessary electron-withdrawing groups for color stability in photographic emulsions. Duty-free when exclusively used in certified photographic chemical production.
4-(N-Ethyl-N-tolylamino)-2-methylaniline
Diaryl amine derivative serving as color developer intermediate for coupler synthesis. The tertiary amine functionality enhances reactivity in photographic color forming reactions. Qualifies under 9817.29.01 for duty-free import to photographic manufacturers.
5-Amino-2-(N-butyl-N-ethylamino)toluene sulfate
Sulfated toluidine derivative used in masked coupler systems for color films. Provides controlled reactivity for improved color reproduction in photographic processing. Aromatic structure with sulfate salt form qualifies for duty-free treatment.
2-(2,4-Di-tert-pentylphenoxy)-N-(3-nitro-2-oxo-1H-indol-3-yl)acetamide
Complex indole-based coupler for high-sensitivity color negative films. The ballasted phenolic structure prevents migration in emulsion layers while maintaining reactivity. Advanced aromatic system qualifies under special photographic chemical tariff provision.
3,3'-Di(2,4,6-trichlorophenyl)-4,4'-diaminodiphenylmethane
Polychlorinated diarylmethane used in stabilizer-coupler systems for color films. Provides both color development and image permanence functions. Heavily substituted aromatic structure qualifies for duty-free photographic import.
