HS 853390 Parts

Quick Answer: Parts for electrical resistors, rheostats, and potentiometers imported under HS 853390 enter the UK and EU duty-free, while the US applies a range of rates, including free entry and a 35% ad valorem duty. This classification covers components specifically designed for use in the manufacture or repair of electrical resistors, variable resistors (rheostats), and adjustable resistors (potentiometers). Importers should verify the specific US tariff line applicable to their product, as the 35% rate is a significant trade consideration. CustomTariffs aggregates this data, highlighting the importance of precise classification for accurate duty assessment across different markets.

How to Classify This HS Code?

```html

What products does HS 853390 cover?

This subheading covers "Parts" of electrical resistors, rheostats and potentiometers, as defined by the World Customs Organization (WCO) Harmonized System (HS) Nomenclature. According to the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database, this includes components specifically designed for the assembly or repair of devices classified under HS heading 8533, such as resistors, rheostats, and potentiometers. Examples include ceramic cores, winding wire, resistive elements, and housings intended solely for these electrical components.

What falls outside HS 853390?

The following products are excluded from HS 853390: finished electrical resistors, rheostats, and potentiometers themselves, which are classified under HS 8533. Additionally, general-purpose tools, raw materials not yet shaped for specific resistor components, and electronic components that are not exclusively for resistors (e.g., general circuit board components) are classified elsewhere. For instance, a complete electronic circuit board containing multiple components would not fall under this subheading.

What are common classification mistakes for HS 853390?

A common error is classifying components that are not exclusively designed for electrical resistors, rheostats, or potentiometers under this subheading. General-purpose wires or insulating materials, for example, may be classified under other headings if their use is not specifically limited to the devices in HS 8533. Misinterpreting 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, can lead to incorrect classification of multi-component parts.

How should importers classify products under HS 853390?

The correct procedure for classifying products under HS 853390 involves a thorough examination of the product's intended use and design. Importers and customs brokers must consult the WCO HS Nomenclature and the specific tariff schedules of the importing country, such as the USITC HTS or the EU TARIC. Verification of whether the part is exclusively designed for electrical resistors, rheostats, or potentiometers is crucial, often requiring technical specifications or manufacturer declarations.

How is the duty calculated for products under HS 853390?

A shipment of 1,000 ceramic cores for resistors, with a declared customs value of $500 USD, would attract a US duty of $25.00. This is calculated using the Most Favored Nation (MFN) rate of 5.0% ad valorem, applied to the declared value ($500 USD × 0.05 = $25.00). This calculation is based on the duty rate published in the USITC Harmonized Tariff Schedule for HS code 8533.90.0000.

Which trade agreements reduce duties for HS 853390?

Several free trade agreements may reduce the applicable duty rate for HS 853390, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty of Free for qualifying goods originating from Canada or Mexico. The EU's Generalised Scheme of Preferences (GSP) may also offer preferential rates, often Free, for goods from certain developing countries. To claim these preferences, documentation such as a USMCA certification of origin or a EUR.1 movement certificate for EU preferences may be required, depending on the specific agreement and origin country.

FAQ

What are the typical import duty rates for HS code 853390 (Parts of resistors, rheostats, potentiometers)?

The import duty rates for HS code 853390, which covers 'Parts' of electrical resistors, rheostats, and potentiometers, can vary significantly depending on the importing country and any applicable trade agreements. For example, under the US Harmonized Tariff Schedule (HTS), the Most Favored Nation (MFN) duty rate is often 0.00% ad valorem. However, preferential rates under trade agreements like the USMCA may also be Free. In contrast, some countries may impose higher duties. It is crucial to consult the specific tariff schedule of the destination country for the most accurate and up-to-date duty information. Always verify with official sources like the USITC HTS, EU TARIC, or UK Trade Tariff.

How is the import duty for HS code 853390 calculated, and can you provide an example?

The duty calculation for HS code 853390 typically depends on whether the duty is ad valorem (a percentage of the value) or specific (a fixed amount per unit). If the duty is ad valorem, the formula is: Duty = (Customs Value of Goods × Duty Rate). For instance, if a shipment of parts for resistors valued at $10,000 USD is imported into a country with a 3.5% ad valorem duty rate, the duty would be $10,000 × 0.035 = $350. If a specific duty applies, the calculation would be based on the quantity (e.g., per piece, per kilogram). Always confirm the basis of duty assessment with the importing country's customs authority.

What documentation is typically required when importing parts classified under HS code 853390?

When importing parts classified under HS code 853390, standard import documentation is generally required. This includes a commercial invoice detailing the value, quantity, and description of the parts; a packing list specifying the contents of each package; and a bill of lading or air waybill for transportation. Depending on the origin and destination, a certificate of origin may be necessary to claim preferential duty rates under trade agreements. Importers should also be prepared to provide technical specifications or product literature if customs authorities require further clarification on the classification of the 'parts' to ensure they are indeed components of electrical resistors, rheostats, or potentiometers.

Are there specific classification criteria to ensure parts fall under HS code 853390 and not other headings?

Yes, the classification of 'parts' under HS code 853390 requires careful consideration. According to the Explanatory Notes to the Harmonized System (HSEN) and general rules of interpretation, parts are generally classified with the finished product they are intended to form. For HS 853390, this means the imported items must be identifiable as components specifically designed for electrical resistors, rheostats, or potentiometers. They should not be general-purpose parts that could be used in a wide variety of electrical equipment. For example, a specialized winding wire for a resistor coil would likely be classified here, whereas a standard screw or casing might be classified elsewhere based on its material or primary function. Customs authorities may request evidence demonstrating the intended use of the parts.

How do trade agreements, such as USMCA or EU trade deals, impact the duty rates for HS code 853390?

Trade agreements can significantly reduce or eliminate import duties for goods classified under HS code 853390, provided the goods meet the rules of origin stipulated in the agreement. For example, under the United States-Mexico-Canada Agreement (USMCA), eligible parts originating from Canada or Mexico may enter the United States duty-free. Similarly, trade agreements between the European Union and third countries can offer preferential rates. To benefit from these agreements, importers must possess a valid certificate of origin and ensure the parts meet the specific regional value content or tariff shift requirements. It is essential to consult the text of the relevant trade agreement and the importing country's customs regulations to confirm eligibility and requirements.
