I'm a licensed US Custom broker for a major freight forwarder here in the US. It never cease to amaze me the type of things that people try to ship as personal effects. If the company is paying for you relocation, no problem, but if this is on your dime, you should think about it.
First is the cost of crating & packaging, this is about $100 if done professionally, shipping cost US-India is around $400-$500 depending on where you start in the US & end in India. This cost is taking into account that you are bringing the TV to the shipping point, and recovering it in India, not requiring the service for a local cartage company.
TV's are duty free if imported to the US, and it should be the same in India. You can google India customs tariffs, (
http://www.cybex.in/Indian-custom-duty/) and will see that it is duty free. The proper schedule b # for this item is 8528.72.6040. You can also claim it as personal effect, but you will need to show proof of ownership and that the item is used. Regardless of which route you take, you will need to indicate the true country of origin, manufacturer, value of goods, & proof of ownership.
In India, you will have to pay some accessorial charges, such as handling and terminal fee, which would be at least $50, on top of that, there is the customs clearance fee, anywhere from $75-&125. Some countries allow you to act as your own broker, (in the US you can as long as commercial value is =< $2500) which could save you the customs clearance fee. I will certainly recommend getting your own insurance, companies like Roanoke, or Washington insurance. This is around $25 or so, otherwise it will be double if you use the forwarders own insurance which is probably provided by the same previous companies I mentioned.
In the end, it is about $575 on the low end for your cost. Only you can determine if this is worth the time and hassle to go through this. You are not the first person doing this, nor the last one. Me personally, I will not do it, you can probably get at most $300-$400 for the used unit, and use that money to buy yourself a new, updated one in India.
I hope this help you and others. Take care.
