4802.55.60.00 - Basic paper to be sensitized for use in photography

This HTS classification specifically covers basic paper and paperboard, not containing fibers obtained by a mechanical or chemi-mechanical process, or where such fibers constitute no more than 10 percent of the total fiber content. These papers and paperboards must weigh between 40 and 150 grams per square meter and be supplied in rolls. The "Basic paper to be sensitized for use in photography" designation within this subcategory highlights a specific end-use application, differentiating it by its intended function for photographic processes, which often requires particular surface treatments or coatings to react with light-sensitive chemicals.

This category distinguishes itself from its sibling, 4802.55.70, through the explicit mention of its use in photographic sensitization. While both fall under the broader umbrella of "Other paper and paperboard" weighing 40-150 g/m² in rolls and not significantly containing mechanically or chemi-mechanically produced fibers, the 4802.55.60.00 classification is reserved for papers specifically prepared for the demanding requirements of photographic reproduction. This implies a specialized surface characteristic or composition that is not necessarily present in the more general "Other" category.

As a leaf node, this classification does not have further subcategories. Therefore, the focus remains on clearly defining the parameters of papers and paperboards meeting the specified weight, format (rolls), fiber content, and crucially, their intended application as a base for photographic sensitization. Proper classification hinges on verifying both the physical attributes and the explicit purpose for which the paper is manufactured.
