Subheadings
Products classified under Tariff item 8533.90.90
Foil Resistor Chip Element 2512 Size
A bulk metal foil resistive element in a 2512 chip format designed for high-current precision applications in servers and test equipment. It features an ultra-low temperature coefficient of resistance (TCR) for stability under load variation. This component is a part of a resistor, not a complete resistor, and is not made of ceramic or metallic materials that are electrically or mechanically reactive to temperature changes, thus falling under 'Other' parts.
Metal Film Precision Resistor Network SIP-10
A single in-line package (SIP) resistor network containing 10 metal film elements for high-precision applications in instrumentation and automotive ECUs. It provides multiple fixed resistances in one compact part. This is a part of a resistor, not a complete resistor, and does not consist of temperature-reactive ceramic or metallic materials, so it falls under 'Other' parts.
NTC Thermistor Bead Assembly
A negative temperature coefficient (NTC) thermistor bead with leads for temperature sensing in HVAC systems and battery management. It consists of a glass-encapsulated ceramic bead. This is a part of a resistor, but since it is not made of ceramic or metallic materials that are electrically or mechanically reactive to temperature changes for the specific goods of tariff item 8533.40.00, it falls under 'Other' parts.
Power Resistor Aluminum Housed Substrate
An aluminum substrate base for chassis-mount power resistors used in power supplies and amplifiers. It provides excellent heat sinking capability and has an anodized surface for electrical insulation. This is a part of a resistor, not a complete resistor, and is not made of temperature-reactive ceramic or metallic materials, so it falls under 'Other' parts.
Rheostat Ceramic Core Replacement Part
A high-temperature ceramic core component for industrial rheostats used in motor speed controls and laboratory equipment. It is designed to withstand high power dissipation. This is a part of a variable resistor, but it is not made of ceramic or metallic materials that are electrically or mechanically reactive to temperature changes for the specific goods of tariff item 8533.40.00, so it falls under 'Other' parts.
SMT Thin Film Resistor Bare Die
An unpackaged thin film resistor die for hybrid circuit assembly in aerospace and medical devices. It offers ultra-precise resistance values with minimal parasitics and is deposited on a silicon substrate. This is a part of a resistor, not a complete resistor, and is not made of temperature-reactive ceramic or metallic materials, so it falls under 'Other' parts.
Thick Film Chip Resistor SMD 0805
Surface-mount thick film chip resistors in 0805 size (2.0 x 1.25 mm) used for current limiting and voltage division in consumer electronics like smartphones and laptops. These are precision parts, but when imported as individual components, they are parts of resistors. They are not made of temperature-reactive ceramic or metallic materials for the specific goods of tariff item 8533.40.00, so they fall under 'Other' parts.
Trimmer Potentiometer Ceramic Substrate
A ceramic substrate with cermet film for surface-mount trimmer potentiometers in telecommunications equipment. It allows fine resistance adjustment post-assembly and uses multi-layer thick film construction. This is a part of a variable resistor, but it is not made of ceramic or metallic materials that are electrically or mechanically reactive to temperature changes for the specific goods of tariff item 8533.40.00, so it falls under 'Other' parts.
Variable Resistor Carbon Disc Element
A carbon disc resistive element for slide and rotary variable resistors in consumer appliances like washing machines and dimmer switches. It provides smooth linear resistance change and is molded from carbon. This is a part of a variable resistor, but it is not made of ceramic or metallic materials that are electrically or mechanically reactive to temperature changes for the specific goods of tariff item 8533.40.00, so it falls under 'Other' parts.
Wirewound Potentiometer Carbon Track Element
A carbon track resistive element for wirewound potentiometers used in volume controls and tuning circuits of audio equipment. This part provides variable resistance adjustment and is classified as 'other' parts. It is not made of temperature-reactive ceramic or metallic materials for the specific goods of tariff item 8533.40.00, so it falls under 'Other' parts.
