HS 847180 Other units of automatic data-processing machines

Quick Answer: Other units of automatic data-processing machines imported under HS 847180 enter the UK and EU duty-free, while US entry is primarily duty-free under the MFN rate, though some subheadings carry a 35% tariff. This classification encompasses a broad range of peripheral devices and auxiliary equipment for automatic data-processing machines that are not specifically covered by other headings within Chapter 84. Examples include magnetic or optical readers, machines for transcribing data onto data media, and devices for outputting data in coded form, such as printers and plotters, when not integrated with the main processing unit. Importers and customs brokers should consult specific national tariff schedules for precise duty rates and any applicable trade agreements or restrictions.

What products does HS 847180 cover?

This subheading covers other units of automatic data-processing machines, not elsewhere specified within heading 8471, as defined by the World Customs Organization's Harmonized System (WCO HS) Nomenclature. This includes peripheral devices that are not integral to the main processing unit but are essential for its operation, such as specialized input/output units, data storage units not covered by 8471.10, and other auxiliary equipment designed to work with automatic data-processing machines, as further detailed in the Explanatory Notes to the Harmonized System and specific national tariff schedules like the USITC Harmonized Tariff Schedule (HTS) or the EU's TARIC database.

What falls outside HS 847180?

The following products are excluded from HS 847180: complete automatic data-processing machines (8471.30, 8471.41, 8471.49), input units (8471.60), output units (8471.60), and storage units (8471.70) if they are considered integral parts of a complete machine. Additionally, devices that are not specifically designed to work with automatic data-processing machines, or those with a primary function other than data processing, such as standalone printers or scanners not directly interfaced for data processing, are classified elsewhere, often under their specific product headings.

What are common classification mistakes for HS 847180?

A common error is misclassifying standalone devices that have data processing capabilities but are not primarily designed as peripheral units for a larger automatic data-processing machine. For instance, a dedicated industrial controller with some data logging functions might be incorrectly placed here instead of under its specific industrial machinery heading. This often arises from misinterpreting the "unit of automatic data-processing machines" requirement, failing to apply General Rule of Interpretation (GRI) 1, which states classification shall be determined according to the terms of the headings and any relative section or chapter notes.

How should importers classify products under HS 847180?

The correct procedure for classifying products under HS 847180 involves a thorough examination of the product's primary function and its relationship to automatic data-processing machines. Importers and customs brokers must consult the WCO HS Explanatory Notes and the specific tariff schedule of the importing country, such as the UK Trade Tariff or the EU TARIC. This includes verifying if the unit is a peripheral device or auxiliary equipment specifically designed to enhance or support the operation of a central processing unit, and not a standalone machine or a component classified elsewhere.

How is the duty calculated for products under HS 847180?

A 10TB external hard drive, designed as a storage unit for automatic data-processing machines, declared at a customs value of $300 USD, would attract a US duty of $15.00. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem published in the USITC Harmonized Tariff Schedule (HTS) for subheading 8471.80.0000 (5.0% × $300 USD = $15.00).

Which trade agreements reduce duties for HS 847180?

Several free trade agreements may reduce the applicable duty rate for HS 847180, including the United States-Mexico-Canada Agreement (USMCA), which can result in a Free duty rate for qualifying goods originating from Canada or Mexico. The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) also offers preferential rates, potentially Free, for originating goods from member countries like Australia or Singapore. To claim these preferences, importers typically require a self-certified origin statement or a specific origin declaration as stipulated by the respective agreement and the importing country's customs regulations.

FAQ

What are the typical import duty rates for HS code 847180, covering 'Other units of automatic data-processing machines'?

The import duty rates for HS code 847180 can vary significantly depending on the importing country and any applicable trade agreements. For example, under the U.S. Harmonized Tariff Schedule (HTS), the Most Favored Nation (MFN) duty rate is 0.00%. In the European Union, under the TARIC system, the rate is also often 0.00% for many origins, though specific rates can apply. The UK Trade Tariff also lists a 0.00% duty rate for this code under its standard import duty. It is crucial to verify the specific rate for your country of import and the country of origin of the goods.

What specific types of 'other units' are classified under HS 847180, and what are the classification criteria?

HS code 847180 is a residual category for units that are part of an automatic data-processing (ADP) system but are not central processing units (CPUs), input/output units, or storage units specifically covered in other subheadings of 8471. Examples include: magnetic or optical readers, machines for transcribing data onto data media, and machines for processing data, not elsewhere specified. The key classification criterion is that the unit must be designed to be used in conjunction with an ADP machine, either directly or indirectly, and must not be classifiable in a more specific heading or subheading. The WCO's Explanatory Notes to Chapter 84 provide further guidance.

How is the import duty for HS 847180 calculated, and can you provide an example?

The duty calculation for HS 847180 typically depends on whether the duty rate is ad valorem (a percentage of the value) or specific (a fixed amount per unit). Assuming an ad valorem rate, the formula is: Duty Amount = (Customs Value of Goods × Duty Rate). For instance, if a shipment of specialized data readers (classified under 847180) has a customs value of $10,000 USD and the applicable duty rate is 3.5% ad valorem, the duty would be $10,000 × 0.035 = $350.00 USD. Always confirm the basis of valuation and the exact duty rate applicable to your specific import.

What documentation is typically required for importing goods classified under HS 847180?

Standard import documentation is generally required for goods under HS 847180. This includes a commercial invoice detailing the goods, quantity, value, and country of origin; a packing list; a bill of lading or air waybill; and a customs declaration. Depending on the importing country and the specific nature of the 'other unit,' additional documentation might be needed, such as technical specifications, proof of compliance with local electronic standards (e.g., FCC in the US, CE marking in the EU), or a certificate of origin to claim preferential duty rates under trade agreements. Importers and customs brokers should consult the specific import regulations of the destination country.

Do common trade agreements, like USMCA or EU Free Trade Agreements, affect the duty rates for HS 847180?

Yes, common trade agreements can significantly affect duty rates for HS code 847180. For goods originating from countries that are signatories to preferential trade agreements with the importing country, the duty rate may be reduced or eliminated entirely. For example, goods originating from Canada or Mexico and meeting the rules of origin under the United States-Mexico-Canada Agreement (USMCA) may enter the U.S. duty-free. Similarly, goods originating from countries with Free Trade Agreements with the EU may benefit from reduced or zero duties under the TARIC system. To claim these benefits, importers must typically provide a valid Certificate of Origin and ensure the goods meet all relevant rules of origin criteria.
