What are restricted in Saudi Arabia?｜Saudi law prohibits importation of the following products: .weapons, alcohol, narcotics, pork and pork products, pornographic materials, distillery equipment, retreaded or used tires, used clothing and certain sculptures

Could you please elaborate on the items that are restricted in Saudi Arabia? I understand Saudi law forbids importing weapons, alcohol, narcotics, pork and pork products, pornographic materials, distillery equipment, retreaded or used tires, used clothing, and some sculptures. But I'm curious, are there any specific reasons behind these restrictions? Also, are there any other items that are similarly prohibited? Could you give some examples of the "certain sculptures" that are not allowed? And what kind of penalties might someone face if they violate these importation restrictions?
