HS Code 8533.21.00.90-6 for PPTC Resettable Fuses
Introduction
In international trade, accurate product classification is efficient operations. The Harmonized System (HS) code provides a globally standardized method for categorizing traded goods. This article delves into HS code 8533.21.00.90-6, specifically for resettable fuses, which have a power limit of 20 watts. We also highlight how Fuzetec PPTC resettable fuses comply with all relevant regulations.
What are HS Codes?
HS codes are used internationally to classify products in trade. These codes help determine tariffs, taxes, and duties, ensuring efficient customs processing. Maintained by the World Customs Organization (WCO), the HS code system is utilized by over 200 countries, facilitating global trade and standardization.
Breaking Down HS Code 8533.21.00.90-6
HS Code Structure
Each part of an HS code provides detailed information about the product:
- 85:Electrical machinery and equipment and parts thereof; sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories of such articles.
- 33:Electrical resistors (including rheostats and potentiometers), other than heating resistors.
- 21:Other fixed resistors.
- 00:Further classification.
- 90-6:Additional specificity for resettable fuses.
Power Limitation of 20 Watts
Importance of Power Rating
For resettable fuses under HS code 8533.21.00.90-6, the power rating is a vital specification. This rating, measured in watts, is the maximum power the device can handle without damage. Resettable fuses in this category are limited to a power rating of 20 watts or less.
Why the Power Limit matters?
- Safety:Operating within the power rating prevents overheating and reduces safety risks.
- Performance:Ensuring the device operates within its power limit guarantees reliable protection.
- Compliance:Adhering to power specifications is often required by regulations, especially in critical safety applications.
Why HS code are so important?
Accurate HS code classification and regulatory compliance are essential when trading resettable fuses. Fuzetec PPTC resettable fuse products fully comply to international standards, ensuring:
- Efficient Customs Clearance:Correct coding and documentation streamline customs processing.
- Legal Compliance:Our products meet global regulatory requirements, reducing the risk of fines and penalties.
- Trust and Reputation:Compliance enhances our reputation with trade partners and regulatory bodies.
Global Trade Implications
The correct use of HS code 8533.21.00.90-6 is important for:
- Determining applicable tariffs and duties
- Ensuring compliance with trade agreements
- Facilitating international transactions successes
Resettable Fuse Products: Technical Overview
How Resettable Fuses Work?
Resettable fuses are important for overcurrent protection in electrical circuits. They automatically limit the current flow to prevent damage happens. When detecting high current or temperature, the resettable fuse increases its resistance, thereby limiting the current. Once the fault is cleared, these devices reset, making them perfect for various applications.
Key Features
- Self-resetting capability
- No need for replacement
- Rapid response to overcurrent events
- Suitable for repeated use
Applications
PPTC Resettable fuses are used in:
- Automotive electronics

FAQs
1. What's the difference between a resettable fuse and a conventional fuse?
Resettable fuses and conventional fuses both protect circuits from overcurrent but operate differently. A conventional fuse is a single-use device that permanently breaks the circuit when the current exceeds a limit, requiring replacement. In contrast, resettable fuses automatically increase their resistance to limit current flow when a fault is detected and reset themselves once the fault is cleared, allowing for repeated use without replacement, which is also very eco-friendly.
2. How do environmental factors affect resettable fuse performance?
Environmental factors like temperature, humidity, and exposure to chemicals can impact resettable fuse performance. High ambient temperatures may cause the fuse to trip at lower current levels, as it relies on heat buildup to function. Exposure to moisture or harsh chemicals can degrade the fuse over time. It is crucial to select resettable fuses rated for the environmental conditions they will encounter.
3. Are resettable fuses suitable for aerospace applications?
Resettable fuses can be used in aerospace applications but must meet stringent safety and reliability standards due to the demanding conditions. Many resettable fuses are designed for consumer electronics, but Fuzetec PPTC Resettable Fuses product had been tested by Outgassing test and rated for high reliability, extreme temperatures, and vibration resistance for aerospace applications. Ensure that the resettable fuses meet the aerospace industry's regulatory and performance standards.
