Pure caffeine has its own specific subheading within the same alkaloid group, taking precedence over 'other' category.
If when pre-formulated into tablets or capsules
Tableted or capsulated medicinal preparations shift to Chapter 30 as finished medicaments rather than bulk chemicals.
If mixed with carriers for industrial extraction
Mixtures exceeding simple solutions become chemical preparations of Chapter 38.
