Understanding Photo Negative & Slide Storage
The category Photo Negative & Slide Storage, identified by Google product category ID 4368, falls under the path Cameras & Optics > Photography > Photo Negative & Slide Storage. It is a level 3 taxonomy classification specifically designed for organizational containers used to preserve film and microscopic slides.
- Archival-quality storage boxes for photographic slides
- Bulk storage units for organized negative preservation
- Microscope slide storage boxes and specialized protective kits
- Protective enclosures for photographic archival maintenance
These examples, based on common listings in the US market, include archival storage boxes, slide kits, and various protective units for microscope slides. If your product is not a dedicated storage container for negatives or slides, it likely belongs in a neighbouring category. Do not place items related to darkroom chemicals or equipment in this category; those belong in Darkroom. Similarly, products intended for studio setups or lighting equipment should be categorized under Lighting & Studio. Items used for physical mounting, such as adhesive corners or display mounts, belong in Photo Mounting Supplies. This category does not have any further subcategories, meaning ID 4368 is the most specific designation available for these types of archival storage products.
To implement this in your feed, you must use either the numeric ID 4368 or the full path: Cameras & Optics > Photography > Photo Negative & Slide Storage. While the attribute is optional, providing it improves classification accuracy. Remember that this attribute remains distinct from your internal product_type field, which allows for your own custom classification schema.
