Subheading 3004.10 covers containing penicillins or derivatives thereof, with a penicillanic acid structure, or streptomycins or their derivatives, within heading 3004.

Under General Rule 6, subheadings are then compared only with others at the same level, so a product is matched against its siblings, not against lines elsewhere in the chapter.
