Description
Fixed resistors for a power handling capacity not exceeding 20W
HS Code 853321 covers surface-mount device (SMD) fixed resistors with a power handling capacity not exceeding 20 watts, which enter the United States duty-free.
Frequently Asked Questions
Do the specific materials used in the construction of SMD resistors, like thick-film ruthenium oxide paste versus thin-film metal alloys, affect their classification under HTS 853321?
No, for this HTS classification, the specific resistive material (e.g., metal film, carbon film, thick-film cermet) does not change the classification, provided the resistors remain 'fixed' and have a power handling capacity not exceeding 20W. The classification under 853321 is defined by the product's function, power rating, and physical form (SMD), making material composition generally irrelevant for tariff purposes.
What specific customs inspection risks exist for SMD resistors classified under HTS 853321?
Shipments of SMD resistors are frequently inspected for undervaluation and misdeclaration of wattage. Customs authorities may verify that the declared power handling capacity (not exceeding 20W) is accurate, as higher wattage resistors fall under a different HTS code. They may also examine the packaging and documentation to ensure the goods are not incorrectly declared as a different electronic component to avoid duties.
For importing SMD resistors (HTS 853321) into the U.S., what are the primary cost factors beyond the product price and standard duty rate?
Beyond the Free Most-Favored-Nation (MFN) duty rate, significant costs include the Free Section 301 tariff imposed on goods of Chinese origin, which applies to most SMD resistors. You must also factor in Merchandise Processing Fees (MPF), which are 0.3464% of the entered value (minimum $29.93, maximum $649.56) per formal entry.
SMD Resistor Material Variants & Classification
The core resistive element material is the primary factor in classifying SMD resistors. Carbon film resistors, including thick or thin film types, are correctly classified under 8533.21. However, resistors with a pure metal or metal alloy resistive element (e.g., metal film, metal foil, or wirewound chip resistors) fall under a different heading, 8533.29. For example, high-precision metal foil SMD chip resistors must be classified under 8533.29.90. Always verify the resistive material specification from the manufacturer's datasheet to ensure correct subheading assignment.
Alternative or Confused Classifications
SMD resistors (8533.21) are most often confused with other passive electronic components. Key alternatives include fixed carbon resistors (8533.29) and thick or thin film chip resistors (also 8533.21, as they are a type of SMD). Crucially, they are distinct from resistor networks or arrays, which are classified under HTS 8533.40, and from variable resistors (potentiometers) under 8533.10. Importers should verify the component's construction and function to avoid misclassification between these closely related headings.
