Import Tips
• Submit assay reports showing >90% metanilic acid content; impurities must not change chemical identity per chapter notes
• Include stabilizer declaration if anticaking agents added, ensuring they qualify under note (f) for preservation only
• Watch for anti-dusting agent additions; excess may trigger reclassification if rendering product for specific use
