Contact your local customs office directly. However as a very broad figure,
just assume 20%..but that's just our complete and utter guess.
Countries use import taxes and laws to prohibit, limit, manage, encourage or
penalise certain goods coming into their country in order to protect the
country's economy. Eg. increase the tax for imports from certain countries due
to political/economic reasons, or indeed some products may be completely
banned.
Note: you
only pay tax on what we declare on the paperwork to customs.
