Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as separate replacement parts without recording unit
Other parts and accessories of electro-diagnostic apparatus classified separately from complete systems.
If suitable for non-medical research applications
Parts for multiple instrument types or non-specific medical use fall under general parts heading per Chapter 90 note 2.
If primarily for electrocardiography rather than gastric function
ECG apparatus has specific subheading; classification depends on primary physiological parameter measured.
