Grouping of exemptions. Each member of a family is entitled to the $800 or $1,600 exemption for articles acquired abroad, subject to the conditions prescribed in this subpart. When members of a family residing in one household travel together on their return to the United States, the $800 or $1,600 exemption to which the several members of the family may be entitled may be grouped and allowed without regard to which member of the family is the owner of the articles. However, a group exemption will not include an exemption for a family member not entitled to it in his own right, nor will a group exemption be applied to any property of such a member. The exemption of a family member who has not attained the age of 21 will not be applied under the group exemption to alcoholic beverages. No exemptions allowable to individuals employed by the household and accompanying the family but not related by blood, marriage, domestic relationship, or adoption will be included in the family grouping.

Members of a family residing in one household. “Members of a family residing in one household” includes all persons who:

Are related by blood, marriage, domestic relationship, or adoption;

Lived together in one household at their last permanent residence; and

Intend to live in one household after their arrival in the United States.

Domestic relationship. As used in paragraph (b)(1) of this section, the term “domestic relationship” includes foster children, stepchildren, half-siblings, legal wards, other dependents, individuals with an in loco parentis or guardianship relationship, and two adults who are in a committed relationship including, but not limited to, long-time companions, and couples in civil unions, or domestic partnerships, wherein the partners are financially interdependent, and are not married to, or a partner of, anyone else. The term “domestic relationship” does not extend to roommates or other cohabitants not otherwise meeting this definition.
