Commodities and products are similar to each other in that a product is a glorified, value added, and differentiated form of commodity. However, there are a number of differences between the two. Commodities are products that cannot be differentiated and, therefore, are sold at the same price universally.

Products, on the other hand, can be differentiated so that value can be added, and can, therefore, be branded and marketed to be sold at different prices depending on the differences in quality. Another major difference between commodity and product is that, commodities are sold usually from business to business to be used as raw material, to manufacture differentiated products. On the other hand, products are sold to consumers who are consistently looking for differentiated products that are better in quality, style etc. 

In summary, commodities are basic, undifferentiated goods that are sold at the same price universally, while products are differentiated and can be sold at different prices based on quality, branding, and marketing. Commodities are typically sold from business to business as raw materials, while products are sold to consumers.
