The Customs Rulings Online Search System, commonly known as CROSS, stands out as an essential public tool for anyone working in tariff classification. It contains legal analysis, detailed product descriptions, references to Section and Chapter Notes, and the logic behind Customs' assignment of specific HTS codes. Used properly, CROSS can make internal classification work more accurate and easier to defend during audits.
This guide walks through how to use CROSS within a compliance-focused workflow, and how to integrate rulings with GRI analysis, internal product information, and documentation practices.
