Last updated: August 2026 dataRough and minimally shaped gemstones other than diamonds — including rubies, sapphires, emeralds, alexandrite, tourmaline, and a wide range of semiprecious varieties — enter under two US lines: unworked stones (7103102000) and those that are sawn or roughly shaped (7103104000). Brazil and Uruguay are the leading sources of US imports under this heading, consistent with their large deposits of quartz-family and colored gemstone rough. Because this heading spans an exceptionally broad range of mineral species, correct classification often depends on whether a stone has received any faceting or polishing — operations that would move it to the worked headings under 710391 or 710399. Importers dealing in mixed rough parcels should document the processing state of each lot carefully.

Customs authorities generally interpret 'roughly shaped' as operations that reduce a stone to an approximate form without creating a finished surface or defined facets. Tumbling that produces a smooth, polished surface or cabochon grinding that creates a domed finished face would likely push the stone into the 'otherwise worked' category under 710391 or 710399. Importers should document the specific processing method to defend classification.
Heat treatment is a widely accepted industry practice for enhancing color and clarity, and it does not by itself constitute 'working' for tariff classification purposes — the stone's physical form remains rough. However, importers should disclose treatment on commercial invoices, as treatment status affects gemological value and may be relevant to CBP appraisement. Fracture-filling or coating that alters the stone's surface could be viewed differently.
