Virtually all products are sold with a barcode on the packaging. Which product categories are however also available without "official" barcode. This will be a very small subset of the categories taxonomy. For prices we need to identify these product categories.

The identification of these bulk categories will be done by adding a property to each relevant category. The property [[Taxonomy_Properties#sales_format|sales_format]] will indicate whether that category is also sold by bulk. This can be by weight (for example almonds), by volume (for example olive oil) or by item (for example lemons).

By adding a proxy category to be used for bulk categories, OFF Prices can show a more simple name. The property '''bulk_proxy_category''' can be used for that. This property points to the [https://world.openfoodfacts.org/category/almonds/ en:almonds] category.
