need to pay sales tax?

Hi all,                                                                                                                                                                                                                        I want to import an electronic product from China.The basic duty for customs is 10% since it's a car fitment.Where the question is that the product is only available in a quantity of 96 numbers.The product is for personal use.I suspect that when it's at customs clearance, will they consider it as an entity to sale?and thus need to pay sales tax?Even though it's larger in number,can i declare them it's for personal use and exclude sales tax.Will they believe me?
