郵寄包裹到美國

I don't know the size and the weight. But I can tell you something in general:

1. Air mail costs double of Surface mail (by sea).

2. Surface mail takes double time than Air mail in transportation.

For items that are small (and not heavy), Always air mail.

http://app1.hongkongpost.com/calc/chi/overseas/step1.php 你可用香港郵政個自動計算器大約計下先．因都唔知你有幾重．以個人經驗．因我成日寄野往加拿大及澳洲的．一條頸巾約＄７０－８０郵費咁上下啦．我指係空郵．如平郵就約＄４０內．或平一半以上．但會耐好多先到．視乎你急唔急啦．空郵往美國之大城市．一般需時７－８工作天．如平郵，即係船運．就要超過一個月先到 ka la. 故多數都係寄空郵啦．除非係寄書之類個 D 一大箱物體 ka jeh. 包裝方面，我會先用膠袋包實．以防有水．外面再用公文袋．書局有唔同 size 賣 ka lak. 密封後往郵局投寄 lor. 呢款叫做小型郵包．磅好，同上郵票，同埋 airmail 藍色貼紙，填好報關 form 即可．報關 form 好細張 ka jar. 冇乜野填的唔使擔心．佢係一張綠色細細張既貼紙．上面你只需填上包裹內 = scarf one piece (一條頸巾）/ 係禮品 Gift / 價值 US$10 / 簽個名寫上日期即可.
