Duties and Taxations
In Malaysia, import duty is mostly imposed ad valorem although some specific duties are imposed on a number of items. Nevertheless, in line with trade liberalisation, import duties on a wide range of raw materials, components and machinery have been abolished, reduced or exempted.
Furthermore, Malaysia is committed to the ASEAN Common Effective Preferential Tariffs (CEPT) scheme under which all industrial goods traded within ASEAN are imposed import duties of 0% to 5%.
Labeling
At this time, there are no specific rules regulating packing imported into Malaysia. It is advantageous although not compulsory to include Malay language wording on product labels. A high percentage of the population speak English but if your product is targeted at the Malays (60% of the population), then it is sensible to provide both languages. The Ministry of Health is responsible for the Production and Sale of Foodstuff Regulations. The Food Act and Regulations prescribe standards, labelling, date marking, and the use of additives and preservatives. |
