HS 845630 Operated by electrodischarge processes
Quick Answer: Machines and apparatus for working any material by electro-discharge processes enter the UK at 2.00%, the EU at 3.50%, and the US with a Most Favored Nation (MFN) rate of 3.5%, though many trade agreements offer duty-free entry. This classification specifically covers equipment that utilizes electrical discharges, such as electrical discharge machining (EDM) or spark erosion machines, to shape or cut materials, typically metals. Importers should be aware of potential variations in preferential duty rates for the US market based on the country of origin. CustomTariffs aggregates this information to assist with compliance.

How to Classify This HS Code?
What products does HS 845630 cover?
This subheading covers machines and apparatus for working materials by electrodischarge processes, as defined by the World Customs Organization (WCO) Harmonized System Nomenclature. This includes electrical discharge machining (EDM) equipment, such as wire EDM and die-sinking EDM machines, which utilize electrical sparks or arcs to erode material. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that these machines are characterized by their ability to precisely cut or shape conductive materials through controlled electrical erosion, often for intricate designs or hard metals.
What falls outside HS 845630?
The following products are excluded from HS 845630: machines that operate by other electro-physical or electro-chemical processes, such as laser-based cutting (typically classified under 8456.10) or electrochemical machining (ECM). Furthermore, general-purpose tools that might incidentally use electrical discharge, but are not specifically designed for material removal via this process, are not included. For instance, welding or soldering equipment, even if employing electrical principles, would be classified elsewhere in Chapter 85.
What are common classification mistakes for HS 845630?
A common error is misclassifying machines that use electrical energy but do not operate by electrodischarge processes. For example, laser cutting machines (HS 8456.10) or plasma cutting machines (HS 8456.40) are distinct technologies. Adherence to General Interpretative Rule 1, which states that classification shall be determined according to the terms of the headings and any relative Section or Chapter Notes, is crucial. Importers must verify the specific working principle of the machine to ensure accurate classification.
How should importers classify products under HS 845630?
The correct procedure for classifying machines under HS 845630 involves a thorough review of the product's technical specifications and operating principles. Importers and customs brokers must confirm that the machine utilizes electrodischarge processes for material removal. Consulting the official tariff schedules of the importing country, such as the USITC HTS or the EU TARIC, and referencing the explanatory notes from the WCO are essential steps to ensure accurate classification.
How is the duty calculated for products under HS 845630?
A Sodick AQ300L wire EDM machine, declared at a customs value of $50,000 USD, would attract a US duty of $3,500.00. This is calculated using the Most Favored Nation (MFN) duty rate of 7.0% ad valorem, as published in the USITC Harmonized Tariff Schedule. The calculation is: 7.0% × $50,000 = $3,500.00. This rate applies to imports from countries not benefiting from preferential trade agreements.
Which trade agreements reduce duties for HS 845630?
Several free trade agreements may reduce the applicable duty rate for HS 845630, 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. Additionally, certain developing countries may benefit from the Generalized System of Preferences (GSP), potentially offering reduced or Free rates. Documentation required typically includes a USMCA Certificate of Origin or a GSP Form A, depending on the origin country and the specific agreement.

FAQ
What is the standard Most Favored Nation (MFN) import duty rate for HS code 845630, 'Machines and apparatus for working any material by electro-discharge processes'?
The standard Most Favored Nation (MFN) import duty rate for HS code 845630 is 3.5% ad valorem. This rate applies to imports from countries not covered by preferential trade agreements. For example, if an item classified under 845630 has an FOB value of $10,000, the MFN duty would be $10,000 \times 0.035 = $350.
How are preferential duty rates applied to HS code 845630 under various trade agreements?
Preferential duty rates for HS code 845630 vary significantly depending on the specific trade agreement. For instance, under certain agreements (e.g., with Australia (AU), South Korea (KR), Singapore (SG)), the duty rate can be Free. It is crucial to consult the specific tariff schedule of the importing country and the relevant trade agreement to determine eligibility and the applicable preferential rate. For example, imports from countries listed with 'Free' under specific agreements would have a 0% duty.
What are the key classification criteria for machines under HS code 845630?
HS code 845630 specifically covers machines and apparatus that utilize electro-discharge processes to work materials. This includes Electrical Discharge Machining (EDM) equipment, such as wire EDM and die-sinking EDM machines. The defining characteristic is the use of electrical discharges (sparks) to erode material, typically for precision cutting, shaping, or drilling of conductive materials. Machines that use other working principles, like laser, waterjet, or mechanical abrasion, would be classified elsewhere.
What documentation is typically required for importing machines classified under HS code 845630?
When importing machines under HS code 845630, standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. Depending on the importing country and the origin of the goods, 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 brochures that clearly demonstrate the machine operates via electro-discharge processes, as this is the key differentiator for this HS code.
Can you provide an example of how duty is calculated for a machine under HS 845630 if a preferential rate of 2.00% applies?
Certainly. If a machine classified under HS code 845630 is imported from a country with a preferential duty rate of 2.00% ad valorem, and the declared customs value of the machine is $50,000, the duty calculation would be: $50,000 (Customs Value) \times 0.02$ (Duty Rate) = $1,000. Therefore, the import duty payable would be $1,000. This calculation is based solely on the value of the goods; other taxes and fees may also apply.
