Dividing Freight/Shipping Costs Up

I have an invoice for 6 different items, some are raw products, some are equipment. Total shipping was $8.50. What is the proper way to divide up shipping costs, given I need each raw product item to have it's shipping figured into the price for costing purposes.
Thanks for any help!
