Use this endpoint when you need official US HTS duty evidence for a specific 10-digit HTS code or want to search by product description. Particularly valuable when importing from China and needing Section 301 tariff applicability signals. Best for pre-import cost estimation and tariff classification research rather than definitive legal tariff advice.

- Customs value must be between 0 and 1,000,000,000 USD
