Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If specifically admiralty metal composition
Admiralty brass has dedicated statistical category within copper-zinc tubes.
If imported pre-coiled for heat exchanger assembly
Coiled tubes for heat exchangers may classify as parts of machinery.
If very thin-walled capillary tubing
Capillary tubes <6mm have separate 'other tube' classification.
