Household Effects & Personal Effects - Customs Duty Guidance
Household effects conditionally included are duty-free. These include such
items as furniture, carpets, paintings, tableware, stereos, linens, and
similar household furnishings; tools of the trade, professional books,
implements, and instruments.
You may import household effects you acquired abroad duty-free if:
You used them abroad for no less than one year.
They are not intended for any other person or for sale.
For Customs purposes, clothing, jewelry, photography equipment, portable
radios, and vehicles are considered personal effects and cannot be brought
in duty-free as household effects. However, duty is usually waived on
personal effects more than one year of age. All vehicles are dutiable.
