Hello Nazlinah, in order to minimize customers' costs, we wrote a low value description on our shipment package already, and try to avoid any extra taxes will be charged by the customs. However, as we stated in our website; if there are any import charges or local customs taxes occurred, buyer is responsible for it.
FAQ: Q: What is your tax policy?
**P.S. Let's share our experience in package deliver to Singapore (no matter by free Standard Shipping or Express Shipping), we haven't receive any customer email saying they have to pay extra tax/custom, this surely ins't any guaranteed, but in our experience, that is very seldom case. If you have special request on the invoice amount about the package, please also mention it in the Remark box when you make the order. :-)
