HS 854320 Signal generators
Quick Answer: Signal generators imported under HS 854320 enter the UK and EU duty-free, while the US applies a duty rate of 35% ad valorem under the Most Favored Nation (MFN) tariff. This HS code encompasses electrical apparatus that generate and emit signals, such as radio frequency (RF) signal generators, function generators, and arbitrary waveform generators, used for testing, measurement, and simulation purposes. Importers should be aware of potential differences in duty rates across major trading blocs. CustomTariffs aggregates this tariff data, highlighting the need for careful consideration of destination country regulations.

How to Classify This HS Code?
What products does HS 854320 cover?
This subheading covers "Signal generators," as defined by the World Customs Organization (WCO) Harmonized System Nomenclature. This includes electronic or electrical apparatus designed to produce signals, such as waveforms (sine, square, triangle, pulse), and often with variable frequency, amplitude, and waveform shape. According to the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database, this category encompasses devices like function generators, arbitrary waveform generators, and RF signal generators used for testing, measurement, and research purposes, excluding those specifically covered elsewhere.
What falls outside HS 854320?
The following products are excluded from HS 854320: devices that generate signals as a secondary function, such as certain types of oscilloscopes with built-in function generators, or signal sources integrated into larger machinery where the signal generation is not the primary purpose. Also excluded are radio transmitters and receivers (heading 8525 or 8527), radar apparatus (heading 8526), and sound or video recording or reproducing apparatus (Chapter 85, other headings). For instance, a simple audio amplifier producing a signal is not a signal generator in this context.
What are common classification mistakes for HS 854320?
A common error is misclassifying complex electronic test equipment that includes signal generation capabilities but whose primary function is measurement or analysis. For example, a spectrum analyzer with a tracking generator might be incorrectly classified under 854320. According to General Rule of Interpretation (GRI) 3(b), goods comprising different materials or components which are to be regarded as a whole, should be classified as if they consisted of the material or component which gives them their essential character. The essential character here would be the measurement function.
How should importers classify products under HS 854320?
The correct procedure for classifying products under HS 854320 involves a thorough examination of the product's primary function and technical specifications. Importers and customs brokers should consult the Explanatory Notes to the Harmonized System, the official tariff schedule of the importing country (e.g., USITC HTS, UK Trade Tariff), and any relevant rulings or decisions. If the apparatus's main purpose is to generate electronic signals for testing, calibration, or research, and it is not specifically classified elsewhere, then 854320 is likely appropriate.
How is the duty calculated for products under HS 854320?
A Keysight 33500B Waveform Generator, declared at a customs value of $1,500 USD, would attract a US duty of $75.00. 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 subheading 8543.20. The calculation is: 5.0% × $1,500 USD = $75.00. This rate applies to goods from countries not benefiting from preferential trade agreements.
Which trade agreements reduce duties for HS 854320?
Several free trade agreements may reduce the applicable duty rate for HS 854320, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for qualifying goods originating from Canada or Mexico. Additionally, the Generalized System of Preferences (GSP) may offer duty-free entry for eligible products from certain developing countries. To claim these preferences, a self-certified origin statement for USMCA or a GSP Form A certificate of origin is typically required, depending on the specific agreement and jurisdiction.

FAQ
What are the typical import duty rates for HS code 854320, 'Signal generators'?
The import duty rates for HS code 854320, 'Signal generators', can vary significantly by country. For example, under the U.S. Harmonized Tariff Schedule (USHTS), the general (MFN) duty rate is Free (0.00%). In the European Union, under TARIC, the rate can be 0.00% for many origins, but specific trade agreements or origin countries may apply different rates. The UK Trade Tariff also shows a general rate of Free (0.00%) for goods from most countries. It is crucial to consult the specific tariff schedule of the importing country and consider the origin of the goods to determine the applicable duty rate.
What specific criteria determine if a device is classified under HS code 854320 as a 'Signal generator'?
HS code 854320 covers 'Signal generators'. Classification under this code generally requires the device to be designed to produce electrical signals, such as waveforms (sine, square, triangle), pulses, or other types of signals, for testing, measurement, or other electronic applications. The key is that the primary function of the apparatus is the generation of these signals. Devices that primarily perform other functions, even if they can generate signals as a secondary feature, may be classified elsewhere. For instance, a function generator used in research and development or for calibrating other equipment would typically fall under this code.
Are there common trade agreements that offer preferential duty rates for signal generators (HS 854320)?
Yes, many trade agreements can provide preferential duty rates for signal generators (HS 854320). For example, goods originating from countries that are part of the European Union's network of Free Trade Agreements (FTAs) may benefit from reduced or eliminated duties when imported into the EU, subject to rules of origin. Similarly, the United States has FTAs with various countries, which could impact duty rates for signal generators imported from those nations. Importers should verify the origin of their signal generators and consult the relevant trade agreement documentation for the importing country to determine eligibility for preferential treatment.
How is the import duty for a signal generator calculated, and can you provide an example?
Import duty is typically calculated based on either an ad valorem rate (a percentage of the declared value of the goods) or a specific rate (a fixed amount per unit of quantity). For HS code 854320, many countries apply an ad valorem rate. For example, if a signal generator is imported into a country with a 3.5% ad valorem duty rate, and the declared customs value of the shipment is $10,000, the duty would be calculated as: 3.5% of $10,000 = $350. It is essential to confirm the specific duty calculation method (ad valorem, specific, or a combination) and the exact rate applicable to the origin and destination country.
What documentation is typically required when importing signal generators under HS code 854320?
When importing signal generators classified under HS code 854320, standard customs documentation is usually required. This includes a commercial invoice detailing the value and description of the goods, a packing list, and a bill of lading or air waybill. Depending on the importing country and the origin of the goods, a certificate of origin may be necessary to claim preferential duty rates under trade agreements. Additionally, technical specifications or datasheets for the signal generators might be requested by customs authorities to verify the classification and ensure compliance with any specific import regulations or standards. Importers should always check the specific requirements of the destination country's customs agency.
