Yes, our price is not included any tax and you have to pay the import tax fee when your fairing package arrived.
Depends on the rule of your country, normally the USA is non-tax needed. Most of the country is setting the charge-tax-line on how much value your package is. In our experience, we only declare USD$100 on your fairing package, somehow it could help you to reduce duty cost, for the exact tax rate, please do double check with your local customs.
We do not ship to post office boxes at this time. In most cases, many Post Offices will return larger packages to sender because they do not accept or cannot handle larger parcels. In order to provide exceptional service and on time delivery of all items we do not ship to post office box addresses.
