Question about a specific Entity Model

I am developing a system for purchasing, storing, and selling products. it should be compatible with different industries like "Food and Beverage", "Apparel and footwear", "Pharmacies" among others.
Some industries might require storing attributes like (Expiry date, Lot no., weight, etc...) for some products and others might not. And may be there is an industry which require storing those information for some products and not for other products.

- What is the right way to define products? Should I only define the product (item_id, name), or define the product and the related attributes in a child table (item_id pk, name) (item_id fk, attribute_id)?
