HS 854089 Other

Quick Answer: Other thermionic, cold cathode or photocathode valves and tubes, including image converters and intensifiers, imported under HS 854089, enter the UK duty-free, the EU at 2.70% ad valorem, and the US at 3.7% ad valorem (MFN). This residual classification applies to valves and tubes not specifically listed elsewhere within heading 8540, such as specialized cathode ray tubes or other less common vacuum tube devices. Importers should verify specific product descriptions against the detailed tariff schedules of their destination country, as subheadings can introduce variations.

How to Classify This HS Code?

```html

What products does HS 854089 cover?

This subheading covers "other" thermionic, cold cathode or photocathode valves and tubes (for example, vacuum or vapour and similar electronic valves and tubes), including cathode ray tubes, and parts thereof, not elsewhere specified or included in heading 8540. According to the WCO Harmonized System Explanatory Notes and definitions found in the USITC Harmonized Tariff Schedule (HTS) and EU TARIC, this residual category captures specialized electronic valves and tubes that do not fit into the more specific subheadings of 8540, such as magnetrons or microwave tubes, provided they meet the general criteria of heading 8540.

What falls outside HS 854089?

The following products are excluded from HS 854089: valves and tubes specifically enumerated in other subheadings of heading 8540, such as magnetrons (8540.40), microwave tubes (8540.60), and cathode ray tubes (8540.11-8540.12). Additionally, solid-state semiconductor devices, even if performing similar functions, are classified under Chapter 85, but in different headings (e.g., 8541 for diodes and transistors). Devices primarily for lighting or display purposes, like LED modules, are also excluded and classified elsewhere.

What are common classification mistakes for HS 854089?

A common error is misclassifying specialized electronic tubes that have a specific function but are not explicitly listed in the more granular subheadings of 8540. This often occurs when importers fail to consult the WCO Explanatory Notes or national tariff schedules, leading them to place items in this residual category when a more precise classification exists. For instance, certain types of specialized gas discharge tubes or high-frequency tubes might have a dedicated subheading that is overlooked, violating General Rule of Interpretation (GRI) 3(a) which prioritizes the most specific description.

How should importers classify products under HS 854089?

The correct procedure for classifying products under HS 854089 involves a systematic approach. Importers and customs brokers must first determine if the product is a thermionic, cold cathode, or photocathode valve or tube. Next, they must meticulously review all preceding subheadings within heading 8540 to ascertain if a more specific classification applies. If the product does not fit any of these more specific categories, and it meets the general definition of heading 8540, then HS 854089 becomes the appropriate classification. Consulting official tariff databases like the USITC HTS or EU TARIC is crucial.

How is the duty calculated for products under HS 854089?

A specific type of specialized vacuum tube, such as a high-power transmitting tube, weighing 2.5 kg and declared at a customs value of $1,500 USD, would attract a US duty of $75.00. This is calculated using the MFN (Most Favored Nation) duty rate of 5.0% ad valorem, applied to the declared value ($1,500 USD × 0.05 = $75.00). This calculation is based on the rates published in the USITC Harmonized Tariff Schedule of the United States (HTSUS) for subheading 8540.89.9000.

Which trade agreements reduce duties for HS 854089?

Several free trade agreements may reduce the applicable duty rate for HS 854089, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for originating goods from Canada and Mexico. Additionally, preferential rates may be available under the Generalized System of Preferences (GSP) for eligible developing countries, potentially offering reduced duties or Free entry. To claim these preferences, importers typically require a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries, depending on the specific agreement and originating country.

FAQ

What are the typical import duty rates for HS code 854089?

HS code 854089, covering 'Other thermionic, cold cathode or photocathode valves and tubes,' generally has a Most Favored Nation (MFN) duty rate of 3.7% in the United States. However, preferential rates under various trade agreements can significantly alter this. For example, goods from Australia (AU), Canada (CA), Chile (CL), South Korea (KR), and Singapore (SG) may enter duty-free under specific agreements. It is crucial to consult the latest USITC Harmonized Tariff Schedule for the most current and applicable rates based on the country of origin.

How is the import duty for HS 854089 calculated, and can you provide an example?

The duty calculation for HS 854089 typically depends on whether the rate is ad valorem (a percentage of the value) or specific (a fixed amount per unit). Assuming an ad valorem rate of 3.7%, if an importer brings in a shipment of specialized vacuum tubes valued at $10,000, the duty would be calculated as follows: $10,000 (value) × 0.037 (duty rate) = $370.00. If the tariff schedule specifies a unit rate, the calculation would be based on the number of units imported multiplied by the specified rate per unit.

What are the key classification criteria for goods falling under HS 854089?

HS code 854089 is a residual category for thermionic, cold cathode, or photocathode valves and tubes that are not specifically classified under other subheadings within HS 8540. This includes items like specialized vacuum tubes for industrial applications, high-frequency power tubes, or other similar electronic components that function based on the control of electron streams in a vacuum or low-pressure gas. To classify correctly, importers must ensure the product is indeed a valve or tube as defined by Chapter 85, Note 1(c) of the Harmonized System, and that it does not fit into more specific headings like 8540.11 (picture tubes), 8540.12 (cathode ray tubes for color television), 8540.20 (cathode ray tubes for color television receivers), 8540.40 (other cathode ray tubes), 8540.60 (other valves and tubes with hot cathode), 8540.71 (magnetrons), 8540.72 (traveling wave tubes), 8540.79 (other valves and tubes with hot cathode), 8540.80 (other valves and tubes with hot cathode), or 8540.91 (parts of cathode ray tubes).

Which trade agreements commonly offer preferential duty rates for HS 854089, and what documentation is needed?

Several trade agreements can provide preferential duty rates for goods classified under HS 854089. For instance, the United States has agreements with countries like Australia (AU), Canada (CA), Chile (CL), South Korea (KR), and Singapore (SG) that may offer duty-free entry. The European Union's TARIC system and the UK Trade Tariff also list preferential rates for various trading partners. To claim preferential treatment, importers typically need a Certificate of Origin or a declaration of origin from the exporter, compliant with the specific requirements of the relevant trade agreement. This documentation must be provided to customs at the time of import.

Are there specific documentation requirements beyond a Certificate of Origin for importing goods under HS 854089?

While a Certificate of Origin is crucial for claiming preferential duty rates, other documentation may be required for HS code 854089 depending on the importing country and the specific nature of the valves or tubes. This can include commercial invoices detailing the value, quantity, and description of the goods; packing lists; bills of lading or air waybills for transport; and potentially technical specifications or datasheets to verify the classification and intended use. In some jurisdictions, specific import licenses or permits might be necessary, especially if the valves or tubes have applications in sensitive industries or technologies. Importers should always consult the customs regulations of the destination country, such as the USITC's Harmonized Tariff Schedule or the EU's TARIC database, and work closely with their customs broker.
