How to fix: Unsupported bulk value: GTIN [gtin]

You submitted a value for the GTIN [gtin] attribute that is reserved for bulk sales of this product. These restricted-range GTIN codes start with “9” as the first indicator digit, and are not available for point-of-sale products.

If the Google product category [google_product_category] of your product requires a Global Trade Item Number (GTIN) as a unique product identifier, then you must submit the correct manufacturer-assigned GTIN for individual saleable products. For example, if you use GTIN-14 codes, only use packaging levels (1-8) when you're selling packages containing multiple products. Do not use the bulk level indicator (9).

For more information about the validation of GTINs, refer to the GTIN Validation Guide.
