How to Classify This HS Code?
What products does HS 910700 cover?
This subheading covers time switches with clock or watch movements specifically designed for use in automatic systems within certain types of aircraft. According to the World Customs Organization (WCO) Harmonized System Nomenclature, these devices are characterized by their integrated timekeeping mechanisms and their specialized application in aviation, ensuring automated functions are performed at precise intervals. The USITC Harmonized Tariff Schedule (HTS) and the EU TARIC database confirm this specific application as the defining criterion for classification under this code.
What falls outside HS 910700?
The following products are excluded from HS 910700: general-purpose time switches not intended for aircraft, such as those used in domestic appliances or industrial machinery, and time switches that lack a clock or watch movement. Furthermore, any automatic system components that do not incorporate a time-switching function, or aircraft components that are not time-related, would be classified under different headings. For instance, standard aircraft chronometers or flight recorders fall under separate HS codes.
What are common classification mistakes for HS 910700?
A common error is misclassifying general-purpose time switches or those intended for non-aviation applications under this specific subheading. This often occurs when the "aircraft" specific use is overlooked, or when the presence of a clock or watch movement is not properly verified. According to the General Rules for the Interpretation of the Harmonized System (GRI), particularly GRI 1, the specific use is a crucial factor in determining classification, and failure to adhere to this can lead to incorrect duty assessments.
How should importers classify products under HS 910700?
The correct procedure for classifying products under HS 910700 involves a detailed examination of the product's specifications and intended use. Importers and customs brokers must verify that the time switch incorporates a clock or watch movement and is explicitly designed for integration into automatic systems within aircraft. Consulting the official tariff schedules of the importing country, such as the USITC HTS or the EU TARIC, and reviewing product technical documentation are essential steps to ensure accurate classification.
How is the duty calculated for products under HS 910700?
A specific aircraft time switch module, weighing 0.5 kg and declared at a customs value of $500 USD, would attract a US duty of $35.00. This is calculated using the Most Favored Nation (MFN) duty rate of 7.0% ad valorem, applied to the declared customs value ($500 USD × 0.07 = $35.00). This calculation is based on the MFN rate published in the USITC Harmonized Tariff Schedule for HS code 910700.0000.
Which trade agreements reduce duties for HS 910700?
Several free trade agreements may reduce the applicable duty rate for HS 910700, including the United States-Mexico-Canada Agreement (USMCA), where qualifying goods may be eligible for Free entry. Additionally, the Generalized System of Preferences (GSP) can offer reduced or Free rates for eligible developing countries. For USMCA, a self-certified origin statement on the invoice is typically required. For GSP, a Form A certificate of origin is often necessary, depending on the importing country's specific requirements.

FAQ
What are the import duty rates for HS code 910700 (Time switches with clock or watch movement for automatic systems in aircraft)?
The Most Favored Nation (MFN) duty rate for HS code 910700 is 4.70% ad valorem. However, preferential duty rates are available under various trade agreements. For example, under the US Free Trade Agreement with Australia (AU), the duty rate is Free. Importers should consult the specific tariff schedule of their importing country and any applicable trade agreements to determine the precise duty rate. For instance, if importing into the US, the duty rate is 4.70% ad valorem. For imports from Australia into the US, the rate is Free.
What specific criteria must a time switch meet to be classified under HS code 910700?
To be classified under HS code 910700, a time switch must meet two primary criteria: 1) It must be equipped with a clock or watch movement. 2) It must be designed for use in automatic systems and specifically intended for certain types of aircraft. This means the device is not a general-purpose timer but a specialized component for aviation applications. For example, a timer used to control aircraft lighting systems or navigation equipment, powered by a clockwork mechanism, would fall under this code. General-purpose timers or those not specifically designed for aircraft would be classified elsewhere.
What documentation is typically required for importing time switches classified under HS code 910700?
When importing time switches under HS code 910700, standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. Additionally, given the specialized nature of this product for aircraft, importers may need to provide a manufacturer's declaration or certificate of conformity confirming that the time switch meets aviation standards and is intended for use in aircraft automatic systems. Customs authorities may also request technical specifications or datasheets to verify the classification. It is advisable to consult with the customs authority of the importing country for any specific or additional documentation requirements.
How is the import duty calculated for HS code 910700, and can you provide an example?
The import duty for HS code 910700 is typically calculated on an ad valorem basis, meaning it is a percentage of the declared customs value of the goods. Using the MFN rate of 4.70% ad valorem as an example: If a shipment of these time switches has a total customs value of $10,000, the import duty would be calculated as follows: Duty Amount = Customs Value × Duty Rate. Duty Amount = $10,000 × 4.70% = $470. Therefore, the import duty would be $470. Some countries may also have specific additional duties or taxes, such as excise taxes or value-added tax (VAT), which would be calculated separately based on their respective rates and the landed cost.
Which major trade agreements offer preferential duty rates for HS code 910700, and what are some examples?
Several trade agreements can provide preferential duty rates for HS code 910700. For instance, the United States has Free Trade Agreements (FTAs) with countries like Australia (AU), South Korea (KR), and Chile (CL), which often grant duty-free entry for goods classified under this code when originating from those countries. The European Union's Generalized Scheme of Preferences (GSP) also offers reduced or zero duties for certain developing countries. For example, if importing from South Korea into the US under the US-Korea FTA, the duty rate would be Free. Importers must ensure they have the necessary proof of origin documentation to claim preferential treatment under these agreements.
