唔應該係 FOB USA 而係 FOB Hong Kong, 如果去到USA, 就應該係 CIF USA port 或者 CNF USA port
你需要問船公司(或forwarder 公司), 喺你香港廠出貨到碼頭或機場之所有費用, 再加你公司嘅成本及所要嘅利潤就等如FOB Hong Kong 嫁喇
That means you need to pay all the charges until the shipment arrived in the destination port.
1) Transportation fee from China to Hong Kong (if any)
2) Transportation fee from your company to warehouse
3) Sea/Air freight charges from Hong Kong to destination
4) Insurance charges (if any)
