from the website of manila forwarder -
"For electronics and taxable items, please email us ahead of time. As a general rule, items should not be more than 12 of a kind. Items that require AC Power to operate have a 10% tariff based on commercial invoice."
so Electric guitar/bass it require ac power di ba so may 10% tax pa pala un kunwari price ng guitar ay $300 10% of it is $30 tariff = $330 + the shipping fee = total cost
Theory ko lang ito.
sana ung naka try na sa mf may help.
