`cross_ruling`

Pack: trade-compliance · Endpoint: https://gateway.pipeworx.io/trade-compliance/mcp

Get one CBP CROSS customs ruling letter in full by its ruling number (e.g. “N305619” or “H301481”, from cross_search). Returns the complete ruling text — the facts presented, CBP’s classification analysis, and the holding — plus the HTS tariff numbers assigned, issue date, and the rulings it modifies, revokes, or is revoked by. Use this to read the actual reasoning behind a tariff classification precedent before relying on it for an entry.
