Silver Halide Sensitization Base Paper
Specialty uncoated paperboard roll at 150 g/m², containing >15% chemi-mechanical fibers, manufactured to exact tolerances for emulsion coating in silver halide photographic films and papers. Classified under HTS 4802.61.50.00 due to its primary purpose as unsensitized base for photographic applications, with properties like dimensional stability critical for darkroom processing.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If marketed for general printing rather than photography
End-use determines classification; paper not specifically for sensitization defaults to other uncoated printing papers in 4802.54, avoiding the photographic proviso.
If used as fluting medium in corrugation
Industrial packaging end-use with semichemical fluting specs shifts to 4805; photo base paper lacks corrugation resistance required for that heading.
If pre-sensitized or emulsion-coated upon import
Paper already sensitized for photography classifies in 4811 as coated specialty paper, not basic uncoated stock.

Import Tips & Compliance
• Include technical data sheets proving intended photographic sensitization use; watch for misdeclaration as printing paper which could trigger 4802.54 duties; test for burst strength if weight exceeds typical photo base to prevent audit issues
