You can put any value on the parcel and it won't matter in the slightest. You can declare the value to be $1M and it has no bearing on the final customs charge paid. Chinese shops have been sending everything declared as "gift" with $1 value and customs officials don't give a shit - the parcel is opened and the official makes an assessment on the worth of the item - if it roughly matches what the shipping document says, that's what they send you an invoice for. If it doesn't, they ask for supporting documentation(receipts of what you paid for the item) and then calculate customs charge off that.
