How is the billable weight determined?

The billable weight is the higher value between the actual physical weight and the dimensional weight calculated via `get_dimensional_weight`.

Can I use my own carrier rates?

Yes, you can provide your own rate matrix to the `calculate_freight_cost` tool to get exact pricing based on your specific carrier contracts.

What information is needed to find a shipping zone?

You need the origin zip code, the destination zip code, and a zone map provided to the `determine_shipping_zone` tool.
