HS 853521 Automatic circuit breakers

Quick Answer: Automatic circuit breakers imported under HS 853521 enter the UK at 2.00%, the EU at 2.70%, and the US at 2.7% under the MFN rate. This classification covers electrical apparatus designed to automatically interrupt an electric circuit when a fault current is detected, such as those used for overcurrent protection in electrical installations. Importers should be aware of potential variations in preferential duty rates for the US based on country of origin. CustomTariffs aggregates this data, highlighting the importance of verifying specific rates for each transaction.

How to Classify This HS Code?

```html

What products does HS 853521 cover?

This subheading covers automatic circuit breakers designed for voltages exceeding 1,000 volts, as defined by the World Customs Organization's Harmonized System (WCO HS) Nomenclature. These devices are crucial for protecting electrical systems from overcurrents and short circuits. According to the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database, this classification specifically applies to those circuit breakers that automatically interrupt electrical flow upon detecting a fault condition, distinguishing them from manually operated switches.

What falls outside HS 853521?

The following products are excluded from HS 853521: automatic circuit breakers for voltages not exceeding 1,000 volts, which are classified under HS 8536. Also excluded are manually operated switches, fuses, and other devices for protecting electrical circuits that do not possess automatic interruption capabilities. For instance, a simple toggle switch or a thermal overload relay without automatic tripping functionality would not fall under this specific subheading, even if used in high-voltage applications.

What are common classification mistakes for HS 853521?

A common error is misinterpreting the voltage threshold. Many importers incorrectly classify automatic circuit breakers designed for lower voltages (under 1,000 volts) under this subheading, when they should be classified under HS 8536. Another mistake involves confusing automatic circuit breakers with other protective devices like surge arresters or disconnect switches that lack the automatic fault-interruption mechanism, thereby violating General Rule of Interpretation (GRI) 1 which states that classification shall be determined according to the terms of the headings and any relative Section or Chapter Notes.

How should importers classify products under HS 853521?

The correct procedure for classifying products under HS 853521 involves a thorough examination of the product's technical specifications, particularly its rated voltage. Importers and customs brokers must verify that the circuit breaker is designed for voltages exceeding 1,000 volts and possesses automatic fault-interruption capabilities. Consulting the official tariff schedules of the importing country, such as the USITC HTS or the EU TARIC, and referencing explanatory notes from the WCO are essential steps to ensure accurate classification.

How is the duty calculated for products under HS 853521?

A specific high-voltage vacuum circuit breaker weighing 500 kg and declared at a customs value of $15,000 USD would attract a US duty of $750.00. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem, as published in the USITC Harmonized Tariff Schedule (HTS) for HS 853521. The calculation is: 5.0% × $15,000 USD = $750.00. This rate applies if no preferential trade agreement is invoked.

Which trade agreements reduce duties for HS 853521?

Several free trade agreements may reduce the applicable duty rate for HS 853521, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for qualifying originating goods from Canada and Mexico. The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) may also offer preferential rates for originating goods from member countries like Japan. To claim these preferences, a self-certified origin statement or a specific certificate of origin, depending on the agreement and jurisdiction, is typically required.

FAQ

What are the typical import duty rates for HS code 853521 (Automatic circuit breakers)?

The Most Favored Nation (MFN) duty rate for automatic circuit breakers under HS code 853521 can vary by country. For example, the United States typically applies a 2.70% ad valorem duty. The European Union, under the TARIC system, may have rates around 2.00% ad valorem. It is crucial to consult the specific tariff schedule of the importing country for the exact rate applicable at the time of import. For instance, the UK Trade Tariff lists a rate of 2.7% ad valorem for this code.

How is the import duty for HS 853521 calculated, and can you provide an example?

The duty for HS code 853521 is typically calculated on an ad valorem basis, meaning a percentage of the declared customs value of the goods. For example, if an importer brings in automatic circuit breakers valued at $10,000 USD and the applicable MFN duty rate is 2.70%, the import duty would be calculated as: $10,000 (Value) × 0.0270 (Duty Rate) = $270.00 (Import Duty). Always ensure the customs value is determined according to the valuation rules of the importing country.

What are the key classification criteria for goods to be classified under HS 853521?

HS code 853521 specifically covers 'Automatic circuit breakers' for a voltage exceeding 1,000 volts. The primary classification criteria are: 1. Functionality: The device must be designed to automatically interrupt electric current when a fault condition (like overcurrent or short circuit) occurs. 2. Voltage: The circuit breaker must be rated for voltages exceeding 1,000 volts. Devices for lower voltages fall under different subheadings. 3. Type: It must be a 'circuit breaker' as opposed to other protective devices like fuses or switches.

Which trade agreements offer preferential duty rates for HS 853521, and what documentation is needed?

Many trade agreements can provide preferential duty rates, often reducing them to Free (0%) or a lower percentage. For example, the USITC Harmonized Tariff Schedule indicates Free entry for goods from countries like Australia (AU), Canada (CA), Chile (CL), South Korea (KR), and Singapore (SG) under certain conditions. To claim preferential treatment, importers typically need a 'Certificate of Origin' or a 'Statement of Origin' issued by the exporter, demonstrating that the goods meet the rules of origin stipulated in the relevant Free Trade Agreement (FTA). Always verify the specific requirements of the FTA and the importing country's customs authority.

Are there specific documentation requirements beyond a commercial invoice and packing list for importing HS 853521?

While a commercial invoice, packing list, and bill of lading are standard, importing automatic circuit breakers (HS 853521) may necessitate additional documentation depending on the importing country's regulations. This can include: 1. Technical Specifications: Proof that the circuit breakers operate at voltages exceeding 1,000 volts might be required. 2. Certifications: Depending on the jurisdiction, safety certifications (e.g., CE marking in the EU, UL listing in the US) may be mandatory or beneficial for customs clearance. 3. Country of Origin Declaration: Essential for determining duty rates and compliance with trade agreements. 4. Import Licenses: In some countries, specific licenses might be required for electrical equipment.
