Customs & Tariff Classification
Binding Ruling
Also known as: Advance Ruling, Customs Ruling
A binding ruling is an official written determination issued by a customs authority, at a trader's request and before importation, that settles how a specific product will be classified, valued, or treated for origin purposes. Because it binds the agency to the stated treatment for identical transactions, a ruling gives importers legal certainty for planning, pricing, and compliance, and it can be relied upon at any port of entry. Traders seek rulings to resolve ambiguous classifications, confirm eligibility for preferential origin, or lock in treatment before committing to a supply chain, and rulings are typically published for the wider trade community.
Underused. A ruling costs nothing but time, is binding on CBP nationally, and converts a recurring argument into a settled fact. Worth it whenever a borderline classification will repeat across many entries — and worth knowing that you must live with the answer, so ask about the article you actually import, not the one you wish you imported.
Where it matters for compliance
- A ruling binds CBP prospectively for the article described. Change the article and the ruling may not travel with it.
- Rulings are published. Competitors read them.
