Understanding the Glass Category
The Glass category, identified by ID 120, falls under the path Hardware > Building Materials > Glass. It is a specific taxonomy level within Google Merchant Center designed to help categorize structural and artistic glass materials used in construction, glazing, or creative projects.
This category is intended for raw or prepared sheets of material intended for fabrication. Examples from the US market include:
- Stained glass sheets used for mosaic or artistic window design.
- Opal and fusible glass packs for kiln-work.
- Clear acrylic or plexiglass sheets used as lightweight safety glazing.
- Mirror sheets designed for building or assembly projects.
Items that do not belong here include finished structural components or building hardware. Specifically, avoid placing Windows, Doors, or Molding in this category, as those have their own specific sections. Additionally, Countertops and Wall & Ceiling Tile represent finished interior installations, while Hardware components like door hinges or locks belong under Door Hardware. If your product is a complete window unit, use the Windows category instead of general glass sheets.
There are no subcategories for this classification, so ID 120 is the most specific level available in the hierarchy.
To implement this in your feed, use the google_product_category attribute. You can provide the numeric value 120 or the full path Hardware > Building Materials > Glass. Remember that this attribute is optional but highly recommended to ensure your products are correctly indexed by Google's automated systems, which improves targeting accuracy.
