or without leadframes, but with no other active or passive circuit elements;
 (iv) Multi‑component integrated circuits (MCOs): a combination of one or more monolithic, hybrid, or multi‑chip integrated circuits with at least one of the following components: silicon‑based sensors, actuators, oscillators, resonators or combinations thereof, or components performing the functions of articles classifiable under 8532, 8533, 8541, or inductors classifiable under 8504, formed to all intents and purposes indivisibly into a single body like an integrated circuit, as a component of a kind used for assembly onto a printed circuit board (PCB) or other carrier, through the connecting of pins, leads, balls, lands, bumps, or pads.
  For the purposes of this definition:
 1. "Components" may be discrete, manufactured independently then assembled onto the rest of the MCO, or integrated into other components.
 2. "Silicon based" means built on a silicon substrate, or made of silicon materials, or manufactured onto integrated circuit die.
 3.(a) "Silicon‑based sensors" consist of microelectronic or mechanical structures that are created in the mass or on the surface of a semiconductor and that have the function of detecting physical or chemical phenomena and transducing these into electric signals, caused by resulting variations in electric properties or displacement of a mechanical structure. "Physical or chemical phenomena" relates to phenomena, such as pressure, acoustic waves, acceleration, vibration, movement, orientation, strain, magnetic field strength, electric field strength, light, radioactivity, humidity, flow, chemicals concentration, etc.
 (b) "Silicon based actuators" consist of microelectronic and mechanical structures that are created in the mass or on the surface of a semiconductor and that have the function of converting electrical signals into physical movement.
 (c) "Silicon based resonators" are components that consist of microelectronic or mechanical structures that are created in the mass or on the surface of a semiconductor and have the function of generating a mechanical or electrical oscillation of a predefined frequency that depends on the physical geometry of these structures in response to an external input.
 (d) "Silicon based oscillators" are active components that consist of microelectronic or mechanical structures that are created in the mass or on the surface of a semiconductor and that have the function of generating a mechanical or electrical oscillation of a predefined frequency that depends on the physical geometry of these structures.
  For the classification of the articles defined in this Note, 8541 and 8542 shall take precedence over any other heading in this Schedule, except in the case of 8523, which might cover them by reference to, in particular, their function.

Subheading Notes.
 1.‑ 8525.81.00 covers only high‑speed television cameras, digital cameras and video camera recorders having one or more of the following characteristics:
 (a) writing speed exceeding 0.5 mm per microsecond;
 (b) time
