Products without weight information cannot be made available for purchase. According to Joom's platform logistics rules, some orders must be fulfilled via online shipping, and weight information is one of its required attributes. 

Product Weight Requirements

1. You must specify product weight for every product and product variant;
2. Product weight's unit of measurements is kilograms (kg).

If a product doesn't have product weight specified when a customer places an order, Joom platform will set the product weight according to the product's public version (last approved product version).

How to Specify Product Weight?

You can specify product weight while creating a new product or editing already existing one. Please refer to the articles How to Add Product? and How to Edit Products? to learn more details.
