Duty free declaration of personal belonging to the US Customs

You may import furniture, dishes, linens, libraries, artwork and similar household furnishings for your personal use free of duty.  To be eligible for duty-free exemption, the articles must have either been available for your use or used in a household where you were a resident for one year.  The year of use does not need to be continuous, nor does it need to be the year immediately before the date of importation.  Personal and household effects entitled to duty-free entry need not accompany you to the United States; you may have them shipped to your U.S. address at a later time if you choose. Your shipment of personal and/or household goods must be cleared through Customs at its first port of arrival, unless you have made arrangements with a foreign freight forwarder to have your effects sent in Customs custody in-bond from the port of arrival to a more convenient port of entry for clearance. (Ask your moving company if they offer this service.)
 
Household effects from the country where these effects were used, and meeting the above criteria, may be entered into the United States duty-free within 10 years after your initial arrival in the United States as a legal resident.
 
Personal effects may be shipped or mailed to you at a later date.  The package should be marked “Used Personal Effects” and must have been in your possession prior to your entry into the United States.  Anything included in the package that is new may be dutiable.

对家庭及私人物品的免税
 
为私人使用的家具、盘子、亚麻布、书籍、工艺品及类似的家居饰品可以免征进口税。符合免税条件的物品应是在一年前获得（但并未使用）或返回美国前使用超过一年的东西。物品被使用的时间不必为连续的一整年，也不必为进口日期前一年的那一年。准许免税进口的私人及家庭用品可不必随行入境，您可以选择您入境后的一段时间后将其运至您指定的地点。您的私人或家庭用品在入境时如没有国外承运人指定更为方便的清关口岸，必须在第一个进口港清关。
 
符合以上条件的在他国使用过的家庭用品可被允许在您第一次以合法居民的身份登陆美国后的10年内免税进口。
 
您在他国使用过的私人物品可被准许在您本人入境后的晚些时候海运或邮寄给您。外包装上面需要标明“用过的私人物品”，而且必须保证是在入美国境之前拥有的。任何包裹中的新物品都有可能被征税。
