Priya.......
You have 9 suitcases too many !!!
Seriously. I urge you to strongly reconsider what you are bringing with you. A person moving here does not require anything except a small amount of clothing, shoes, and very nominal personal affects. You can cheaply and easily buy anything else you will need locally for less than the cost of shipping it in most cases. If there are 3-4 other people coming with you, then I can understand the 10 suitcases.
A foreigner going thru the green line (nothing to declare line) at GRU with 10 suitcases has a probability of 95% of getting pulled aside for a secondary inspection at customs. The RF officers prowl around the luggage carousels looking for people like you. If anything you are bringing in is semi expensive and in a quantity of more than one for personal use, and appears to be a commercial importation for resale, you can expect it to potentially be seized and you'll receive a fine. If it appears work related and you don't have a valid work visa, your problem just got a whole lot worse. Just saying......
FWIW we shipped 18 small boxes of personal effects here from our house in Canada to Rio. Literally got rid off an entire house full of contents and narrowed it down to this stuff in 18 small boxes. My wife insisted on bringing it and we wasted R$30.000 shipping it here. It was a pointless exercise. And then we changed plans and shipped it from Rio to Petropolis, one hour away. It cost us R$1.000 to route the boxes 150 km from the storage depot in Rio to our apartment in Petropolis.......trucking companies make you pay for two way freight, loaded to the destination, and empty coming back. I am still pissed about it 6 months later as it was a total waste of money. You'd be better off renting a van @ Localiza (a popular rent a car place) but the problem then becomes you have to drive, and you are paying for a one way rental, which is also expensive with mileage charges. Localiza, Avis, Hertz, etc, all the rental companies have vans at GRU. If you go this route, you had better book it online ASAP though.
I've sent you a private message with the email and site link of my freight forwarder I used in September to move here. She can arrange customs clearance and transport to your final destination. They were very efficient and she speaks perfect english. Her name is Ingrid Anzai @ Transworld Mudancas.
Good luck.
