You may not carry sand/soil into the United State. In ports where this is prevalent (e.g., pink sands of Bermuda), the ship is carefully watching for such items and there is always a pile of bottles of sand at the gangway.
Customs: "All travelers entering the United States are REQUIRED to DECLARE meats, fruits, vegetables, plants, seeds, soil, animals, as well as plant and animal products (including soup or soup products) they may be carrying.
Prohibited items that are not declared by passengers are confiscated and disposed of by CBP agriculture specialists. More importantly, civil penalties may be assessed for failure to declare prohibited agricultural products and may range up to $1,000 per first-time offense for non-commercial quantities.
No soil or earth of any kind is allowed into the United States without a permit issued in advance by USDA Plant Protection and Quarantine Permit Unit. Pure sand, such as a small container of decorative beach sand, is usually allowed."
