HS Code for Carbon film resistors

Carbon film resistors are classified under HS code 8533.10. This code is situated within Chapter 85, which encompasses electrical machinery and equipment. Heading 8533 specifically covers electrical resistors (including rheostats and potentiometers), other than heating resistors. Subheading 8533.10 is dedicated to fixed carbon resistors, which include both composition types and film types. Carbon film resistors are manufactured by depositing a thin layer of carbon onto a ceramic substrate. This layer acts as the resistive element. The classification is straightforward based on the function (electrical resistance) and the material (carbon film). It excludes heating resistors, which are classified under 8516. These components are ubiquitous in electronic circuits, used to limit current flow, provide voltage division, and protect sensitive components. The classification under 8533.10 is determined by the fact that the resistive element is made of carbon and that the resistor is a "fixed" type, meaning its resistance value cannot be adjusted. This distinguishes it from variable resistors or potentiometers found in other subheadings of 8533. The precision and power rating of the resistor do not change its primary classification under this code.

Products Included

• Fixed carbon film resistors
• Carbon composition resistors
• Carbon film resistor networks (fixed)
• Axial lead carbon resistors

Common Misclassification

Carbon film resistors are often confused with metal film resistors, which are classified under 8533.21 (if under 20W). They are also occasionally misclassified under 8545 as carbon electrodes, though their function is resistive rather than conductive.

FAQ

What is the HS code for Carbon film resistors?

The HS code for fixed carbon film resistors is 8533.10.

How do they differ from metal film resistors?

Carbon film resistors use a carbon layer as the resistive element (8533.10), while metal film resistors use a metal or metal oxide layer and are classified under 8533.21.
