9018.11.30.00 - Electrocardiographs

This category specifically covers electrocardiographs (ECGs), which are medical devices designed to record the electrical activity of the heart. These instruments are crucial for diagnosing various cardiac conditions by analyzing waveforms such as P waves, QRS complexes, and T waves. The recorded data helps physicians assess heart rhythm, detect abnormalities like arrhythmias, myocardial infarction, and hypertrophy, and monitor the effectiveness of cardiac treatments.

While the parent heading encompasses a broader range of electro-diagnostic apparatus, HTS code 9018.11.30.00 is precisely for the complete electrocardiograph units themselves. This distinguishes it from sibling categories like 9018.11.60.00, which covers printed circuit assemblies that may be components *of* an electrocardiograph, and 9018.11.90.00, which is a residual category for other electro-diagnostic apparatus not otherwise specified. The focus here is on the functional, integrated device used for real-time or recorded cardiac electrical activity measurement.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification under 9018.11.30.00 should be made when the imported article is a complete, operational electrocardiograph, regardless of whether it is a portable unit, a stationary hospital model, or a system designed for professional medical use. Components, accessories, or parts that do not constitute the entire functional electrocardiograph unit would be classified elsewhere.
