I want to configure Google structured data for a product details page with its shipping price. But I see additional properties deliveryTime and transitTime in the Google documentation. I am not sure if these properties are mandatory or optional to implement along with shippingRate. Secondly, how can we figure out on Schema.org, which property is mandatory and which is not?

What’s required by Google to consider structured data valid can be just a subset of what’s required for certain Google search features like rich snippets.
Google’s documentation categorises properties into ‘required’ and ‘recommended’ for each supported type. In your case, the Offer type’s properties are documented by Google here:
The documentation says price or priceSpecification.price are required, and priceValidUntil among others are recommended.
You mention deliveryTime and transitTime. The above link slightly further down documents
ShippingDeliveryTime
This type is not used by product snippets.
so it is useful to include for purposes other than product snippets.
Schema.org is just the schema. It doesn’t say what properties are required for specific Google functionality.
