How to Classify This HS Code?
What products does HS 845720 cover?
This subheading covers "Unit construction machines (single station)" as defined by the World Customs Organization (WCO) Harmonized System Nomenclature. These are machines designed to perform a single operation or a series of operations at one workstation, typically for metalworking. According to the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database, these machines are characterized by their fixed configuration and single-station operation, distinguishing them from multi-station transfer machines or machining centers.
What falls outside HS 845720?
The following products are excluded from HS 845720: machines designed for multiple stations or for performing a sequence of operations at different stations (classified under 8457.10), and machines that are not primarily for metalworking, such as those for woodworking or plastic working. Also excluded are general-purpose machine tools that do not fit the specific definition of a single-station unit construction machine, like standard lathes or milling machines not configured for automated, single-station operations.
What are common classification mistakes for HS 845720?
A common error is misclassifying multi-station machines or machining centers as single-station unit construction machines. General Interpretative Rule 1 (GIR 1) of the Harmonized System dictates that classification shall be determined according to the terms of the headings and any relative Section or Chapter Notes. Importers may also incorrectly classify machines that perform multiple unrelated operations at a single station if they are not specifically designed as a "unit construction machine" for a particular manufacturing process.
How should importers classify products under HS 845720?
The correct procedure for classifying products under HS 845720 involves a thorough examination of the machine's design and intended function. Importers and customs brokers must determine if the machine operates at a single station and is designed for a specific manufacturing sequence or operation, as per the WCO's Explanatory Notes. Consulting the specific tariff schedule of the importing country, such as the USITC HTS or the UK Trade Tariff, and reviewing product literature and technical specifications are crucial steps.
How is the duty calculated for products under HS 845720?
A hypothetical CNC single-station drilling machine weighing 5,000 kg and declared at a customs value of $50,000 USD would, under the USITC Harmonized Tariff Schedule (HTS) with a Most Favored Nation (MFN) duty rate of 3.5% ad valorem, attract a US duty of $1,750. This is calculated as 3.5% × $50,000 = $1,750. The specific duty rate can vary significantly based on the importing country and any applicable trade agreements.
Which trade agreements reduce duties for HS 845720?
Several free trade agreements may reduce the applicable duty rate for HS 845720, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for qualifying goods originating from Canada or Mexico, requiring a self-certified origin statement. For imports into the European Union, agreements with countries like Switzerland might offer preferential rates, potentially Free, contingent upon a EUR.1 movement certificate. The United Kingdom also has similar agreements offering preferential rates with appropriate documentation.

FAQ
What are the typical import duty rates for HS code 8457.20 (Unit construction machines, single station)?
The Most Favored Nation (MFN) duty rate for HS code 8457.20 can vary. For example, the U.S. tariff rate is 2.70% ad valorem. However, preferential rates are often available under various trade agreements. For instance, duty-free entry (Free) may be granted for imports from countries such as Australia (AU), the European Union (E), South Korea (KR), and Singapore (SG), among others, provided specific rules of origin are met. Always verify the applicable rate based on the country of origin and relevant trade agreements.
How is HS code 8457.20 classified? What defines a 'single station' unit construction machine?
HS code 8457.20 covers 'Unit construction machines (single station)'. Classification hinges on the machine's primary function and configuration. A single station machine performs a specific operation (e.g., drilling, milling, tapping) at one work station. It is not a transfer machine with multiple stations linked by an automatic work-piece transfer system. The machine typically has a workpiece holding device and a tool-holding and driving unit, performing operations sequentially at that single station. Refer to Chapter 84 notes and Explanatory Notes from the WCO for detailed classification guidance.
Can you provide an example of how import duty is calculated for HS 8457.20?
Certainly. Let's assume an import of a single station unit construction machine from a country with a 2.70% MFN ad valorem duty rate. If the declared customs value of the machine is $50,000 USD, the import duty would be calculated as follows: Duty Amount = Declared Value × Duty Rate. Duty Amount = $50,000 × 2.70% = $1,350 USD. This calculation applies to ad valorem duties, which are based on the value of the imported goods.
What documentation is typically required for importing machines classified under HS 8457.20?
When importing machines under HS code 8457.20, standard import documentation is generally required. This includes a commercial invoice detailing the machine's description, quantity, value, and country of origin; a packing list; a bill of lading or air waybill; and potentially a certificate of origin to claim preferential duty rates. Depending on the country of import and the specific machine, additional certifications or permits related to safety standards, electrical compliance, or environmental regulations might be necessary. Consulting the importing country's customs authority (e.g., USITC, UK Trade Tariff) is crucial.
Which major trade agreements commonly offer reduced or zero duty rates for HS 8457.20?
Several trade agreements can provide preferential duty rates for HS 8457.20. For instance, the United States has agreements like the USMCA (United States-Mexico-Canada Agreement) which may offer preferential treatment between these nations. The EU's TARIC system reflects preferences under agreements with countries like Switzerland, Norway, and various Mediterranean and African, Caribbean, and Pacific (ACP) states. The UK Trade Tariff similarly lists preferences under its Global Tariff and various Free Trade Agreements. Importers should always check the specific provisions and rules of origin for agreements relevant to their country of origin and destination to determine eligibility for reduced or free entry.
