nope
there's a rather naughty way of avoiding tax.
to put simply. i always hear of people being billed GST on top of CIF + cost of the bass(or any other gear for that matter), this is because the item will be delivered to you, thus, making you liable for the service that you receive when u get the item.( GST for the act of local reception of item)
usually what i do is, when i know the tracking number and estimated arrival date, i give singpost a call and tell them specifically.
LEAVE THE ITEM AT POST OFFICE, i will collect meself. and they are ok with it. so i'd pop over to singpost office and collect the item. just show IC to verify ID and give them the tracking number. even though items were over S$400. they dont charge me anything. done this with both EMS shipped items and Vpost shipped items.
no extra payment beyond what you have paid for item and CIF. no GST. not sure if this is counted tax evasion since you dont use a service. they ship it to you and so as long as the good reach the customer and they dont ship from their end node to your home. its not considered a service provided since you basically self collect.
