HS 854079 Other
Quick Answer: Other thermionic, cold cathode or photocathode valves and tubes, including valves and tubes with built-in magnets, imported under HS 854079 enter the UK duty-free, the EU at 2.70% ad valorem, and the US at 3.3% ad valorem (or free for specific trade agreement partners). This residual category encompasses valves and tubes not specifically classified elsewhere within heading 8540, such as specialized cathode ray tubes or certain gas discharge tubes. Importers should verify specific product descriptions against the full tariff schedules to ensure correct classification, as minor variations can lead to different duty rates.

How to Classify This HS Code?
What products does HS 854079 cover?
This subheading covers "Other" thermionic, cold cathode or photocathode valves and tubes, including cathode ray tubes, and parts thereof, not elsewhere specified within heading 8540. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this residual category captures valves and tubes that do not fit the more specific subheadings of 8540.71 (for microwave tubes) or 8540.72 (for other tubes with hot cathode). Official definitions from sources like the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC database confirm that this subheading is a catch-all for such electronic components.
What falls outside HS 854079?
The following products are excluded from HS 854079: specifically identified microwave tubes (classified under 8540.71), other thermionic, cold cathode, or photocathode tubes with hot cathodes (classified under 8540.72), and all other types of valves and tubes covered by the broader heading 8540, such as cathode ray tubes for television receivers (8540.11) or display units (8540.12). Solid-state semiconductor devices, even if performing similar functions, are also excluded and typically fall under Chapter 85, Subheading 8541.
What are common classification mistakes for HS 854079?
A common error is misclassifying specialized valves and tubes that, despite being "other" in a general sense, have specific functional descriptions that align with more precise subheadings within 8540 or even other headings entirely. For instance, a tube primarily designed for specific industrial heating applications might be mistakenly placed here instead of a more appropriate industrial equipment heading. Adherence to the General Rules for the Interpretation of the Harmonized System (GRI), particularly GRI 1 and GRI 3, is crucial to ensure correct classification based on the most specific description.
How should importers classify products under HS 854079?
The correct procedure for classifying products under HS 854079 involves a detailed examination of the product's technical specifications and intended use. Importers and customs brokers must first consult the WCO HS Explanatory Notes and the specific national tariff schedules (e.g., USITC HTS, EU TARIC, UK Trade Tariff) to determine if the product fits a more specific subheading. If the product is a thermionic, cold cathode, or photocathode valve or tube, and does not meet the criteria for 8540.71 or 8540.72, and is not otherwise classified, then 8540.79 is the appropriate classification.
How is the duty calculated for products under HS 854079?
A specific, non-microwave, non-hot cathode thermionic valve, weighing 0.5 kg and declared at a customs value of $1,000 USD, would attract a US duty of $35.00. This is calculated using the U.S. Most Favored Nation (MFN) duty rate of 3.5% ad valorem, applied to the declared value: 3.5% × $1,000 USD = $35.00. This calculation is based on the rates published in the USITC Harmonized Tariff Schedule (HTS) for subheading 8540.79.9000.
Which trade agreements reduce duties for HS 854079?
Several free trade agreements may reduce the applicable duty rate for HS 854079, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for originating goods from Canada and Mexico. The Generalized System of Preferences (GSP) may also offer preferential rates, often Free, for eligible goods from developing countries such as Vietnam. To claim these preferences, a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries is typically required, depending on the specific jurisdiction and agreement.

FAQ
What are the typical import duty rates for HS code 854079?
HS code 854079, which covers 'Other thermionic, cold cathode or photocathode valves and tubes,' has varying duty rates depending on the importing country. For instance, the U.S. Most Favored Nation (MFN) rate is 0.00%. In the European Union, under the TARIC system, the rate can be 3.3% ad valorem. The UK Trade Tariff also lists a duty rate of 3.3% ad valorem. It is crucial to consult the specific tariff schedule of the destination country for the most accurate and up-to-date duty rate.
How is the import duty for HS 854079 calculated, and can you provide an example?
The duty calculation for HS 854079 typically involves an ad valorem rate, meaning a percentage of the declared customs value of the goods. For example, if a shipment of goods classified under 854079 has a customs value of $10,000 and the applicable duty rate is 3.3% ad valorem, the import duty would be calculated as: $10,000 (Customs Value) × 0.033 (Duty Rate) = $330.00. Always ensure the customs value is correctly determined according to the relevant valuation rules.
What are the classification criteria for goods falling under HS code 854079?
HS code 854079 is a residual category for thermionic, cold cathode, or photocathode valves and tubes that are not specifically classified under other headings within Chapter 85. This includes specialized valves and tubes not covered by more specific subheadings, such as certain types of magnetrons, klystrons, or other high-frequency tubes, provided they meet the general definition of valves and tubes in HS 8540. Importers must ensure the product does not fit into a more specific HS code before classifying it here.
Which trade agreements offer preferential duty rates for HS 854079, and how can I verify them?
Preferential duty rates for HS 854079 are available under various trade agreements. For example, the U.S. offers 'Free' duty rates under agreements with countries like Australia (AU), Canada (CA), Chile (CL), South Korea (KR), and Singapore (SG), among others listed under the 'Free' category. To verify these preferential rates, importers and brokers should consult the preferential tariff schedules of the importing country, often accessible through official government trade websites (e.g., USITC.gov for U.S. rates, or the EU's TARIC database for EU rates). Proof of origin, such as a Certificate of Origin, is typically required to claim these benefits.
What documentation is typically required when importing goods under HS code 854079?
When importing goods classified under HS code 854079, standard import documentation is generally required. This includes a commercial invoice detailing the value, quantity, and description of the goods; a packing list; and a bill of lading or air waybill for transportation. Depending on the importing country and the specific nature of the valves or tubes, additional documentation might be necessary, such as a Certificate of Origin to claim preferential duty rates, or specific safety or technical compliance certificates. It is advisable to consult the customs authority of the destination country for a comprehensive list of required documents.
