# JEITA publishes completion guidance highlighting CMRT 6.5 smelter look-up discrepancies and workaround

## Description

A JEITA CMRT completion guide (English PDF) documents a practical data-quality/validation issue for CMRT Rev. 6.5: some smelters (example noted for tin) may appear on a conformant smelter list but be absent from CMRT 6.5’s Smelter Look-up tab, which can trigger CID entry/validation errors. JEITA advises using the 'Smelter Not Listed' option and manually entering smelter details in such cases. Compliance teams using CMRT intake automation should ensure exception-handling for 'not listed' entries and adjust validation rules to reduce supplier rejection loops.
