According to the Government of Malaysia, a Sales and Services Tax is imposed on goods imported to Malaysia, which includes overseas goods bought in online shopping. There is SST relief for goods with a CIF value of RM500 or below. In other words, you do not have to pay any SST if the total CIF value of your shipment is under the threshold. However, please be mindful that there are some exceptional cases. The Customs have the final decision on how to assess duty and tax.
The tax and duty may be subject to change due to the policy. If there are any discrepancies or differences among the information of taxation and duty, the information provided by the Malaysian Customs or other government authorities shall prevail.
For further details, please refer to Taxation or information provided by the Malaysian Customs.
