Photographic paper, paperboard and textiles; (for other than colour photography, other than in rolls of a width exceeding 610mm), sensitised, unexposed

HS code 370390 covers a range of photographic materials, including paper, paperboard, and textiles, that are sensitized and unexposed. These products are essential for the photography industry, enabling the capture and preservation of images. They find applications in various sectors, from commercial and artistic photography to medical imaging and security documentation, making them a crucial component of the broader imaging and visual communication ecosystem.

The production of photographic paper, paperboard, and textiles under HS code 370390 typically involves a multi-step process. First, the base material, such as paper or textile, is coated with a light-sensitive emulsion, often containing silver halides or other photosensitive compounds. This coating process is carefully controlled to ensure an even and consistent application. The coated material is then dried and cut to the desired size or format, ready for use in various photographic applications.

The main inputs required for the production of HS code 370390 products include the base materials (paper, paperboard, or textiles), photosensitive chemicals (such as silver halides), and specialized coating and drying equipment. Additionally, the industry relies on a skilled workforce capable of operating the production machinery and maintaining quality control standards. Energy sources, such as electricity or natural gas, are also essential for the drying and processing stages.

The primary outputs of HS code 370390 are photographic paper, paperboard, and textiles that can be used for a variety of photographic applications. These products are often consumed by other industries, such as 370110 Photographic plates and film in the flat, sensitised, unexposed, of any material other than paper, paperboard or textiles, 370120 Photographic film in rolls, sensitised, unexposed, of any material other than paper, paperboard or textiles, and 370210 (Photographic film in rolls, sensitised, unexposed, for colour photography (polychrome)), which rely on these sensitized materials for their own photographic processes.
