If kastam kantoi (which they usually do), they will force you to get SIRIM approval before you can claim your item. Happened to my phone from China before.

Anything new with box, if kastam opened and check and if under taxation rules, then they will hold the item and the courier will issue you a notice to pickup.

But if sent as a 'gift' (without its ori box) high chance for your item not to be held. Make sure you have tracking service enabled as you will know the status.

If got held, they will want to see your receipt and then tax your accordingly, and you gotta pay before reclaiming your item.

By percentage, I think I paid 10%. Should be around there. End up paid higher than buying local.

Paying more is more common than you think, even if you bought the item physically overseas.
