For reasons unknown it is very hard to get India to talk about bare crankcases. At one time I heard something to the tune that shipping a bare crankcase put folks in India out of a job, I guess assembling engines. All sounds far fetched to me.
My supplier says not available when I have asked and I dropped it. Irregaudless of all that a crankcase could be stopped by an overzellous customs officer and tagged as contraband which would condemn the entire shipment. Yes also far fetched but none the less a gamble I won't take, sorry.
