I have imported different sort of things from California over the past years, e.g. Cisco routers, laptops and machinery/parts.
There is a customs & duty tariff on FBR's website but the problem with that is, it is merely a formal paper. The clever whips at clearance put everything on invoice that they want. For instance, once they even charged duty on a small $50 book although the tariff says otherwise.
Try using DHL; they have a clearing department and will guide you through. Stay away from FedEx, they will rip you off.
Your final invoice will be a pretttttttttttttttty BIG one. What will it have? See this for an example that I posted sometime earlier this month:
Also, remember, whatever they put on the invoice, you WILL have to pay it, otherwise your shipment is held and auctioned/sold or whatever they want to do with it
