I will be landing at New Delhi airport. The worth of new laptop (Lenovo Yoga Idea Pad 13) is about $1000 and old one (Macbook Pro) is > 1 lakh INR. I want to leave the new laptop in India. I have a copy of bill with me but not the original bill. I want to know if I have risk of being charged with custom duty.
Customs rules in India state (the 'free allowance' referred to is for personal items, and the duty-free allowance of alcohol cigarettes):
EDIT: It seems that an invoice isn't valid as a proof of purchase. Specifically, you'd need to get an 'export certificate' before flying out of India.
