How to Classify This HS Code?
What products does HS 845970 cover?
This subheading covers "Other threading or tapping machines" not elsewhere specified within heading 8459, which pertains to machine tools for drilling, boring, milling, and thread-cutting. According to the World Customs Organization (WCO) Harmonized System Explanatory Notes, this category includes machines designed specifically for cutting internal or external screw threads or for tapping internal threads in workpieces. These machines are distinct from general-purpose lathes or milling machines that may also perform threading operations as a secondary function.
What falls outside HS 845970?
The following products are excluded from HS 845970: general-purpose lathes (8458), milling machines (8457), and machines for cutting gears (8461). Also excluded are portable electric tools for threading or tapping, which are typically classified under heading 8467. Machines that perform threading as a secondary operation, where its primary function is drilling, milling, or boring, would also be classified under their primary function heading, not 845970.
What are common classification mistakes for HS 845970?
A common error is misclassifying multi-functional machines. If a machine is primarily designed for drilling but can also perform threading, it should be classified according to its principal function, often guided by General Rule of Interpretation (GRI) 3(b) which prioritizes the essential character of the good. Importers may also incorrectly classify portable electric threading tools under this heading, when they belong to HS 8467.
How should importers classify products under HS 845970?
The correct procedure for classifying machines under HS 845970 involves a thorough examination of the machine's primary function and design. Importers and customs brokers must consult the official tariff schedule of the importing country, such as the USITC Harmonized Tariff Schedule (HTS) or the EU's TARIC database, and review the Explanatory Notes from the WCO. Confirming that the machine's sole or principal purpose is threading or tapping, and that it is not covered by more specific headings, is crucial.
How is the duty calculated for products under HS 845970?
A "Model T-300 Automatic Pipe Threading Machine" weighing 500 kg and declared at a customs value of $15,000 USD would attract a US duty of $750.00. This is calculated using the Most Favored Nation (MFN) rate of 5.0% ad valorem, applied to the declared value: 5.0% × $15,000 = $750.00. This calculation is based on the MFN rate published in the USITC Harmonized Tariff Schedule for HS code 8459.70.0000.
Which trade agreements reduce duties for HS 845970?
Several free trade agreements may reduce the applicable duty rate for HS 845970, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, eligible machines originating from Canada or Mexico can enter the US duty-free. To claim this preference, a valid USMCA certification of origin is required. The EU's Generalized System of Preferences (GSP) may also offer reduced or zero duties for eligible developing countries, requiring a EUR.1 movement certificate or a self-certified origin declaration.

FAQ
What are the typical import duty rates for HS code 845970, 'Other threading or tapping machines'?
The Most Favored Nation (MFN) duty rate for HS code 845970 can vary. For example, under the US tariff schedule, the MFN rate is 2.00% ad valorem. However, preferential rates are often available for goods imported from countries with trade agreements. For instance, rates can be Free (0.00%) for imports from countries like Australia (AU), Chile (CL), South Korea (KR), and Singapore (SG), among others listed under the 'A,AU,BH,CL,CO,D,E,IL,JO,KR,MA,OM,P,PA,PE,S,SG' designation. It is crucial to consult the specific tariff schedule of the importing country and verify eligibility for preferential treatment based on the country of origin and applicable trade agreements.
How is the import duty for HS code 845970 calculated, and can you provide an example?
The import duty for HS code 845970 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the goods. For example, if a machine classified under HS 845970 has a customs value of $10,000 and the applicable MFN duty rate is 2.00%, the import duty would be calculated as: $10,000 (Customs Value) × 0.02 (Duty Rate) = $200. If the machine is subject to a specific duty or a combination of ad valorem and specific duties, the calculation would be adjusted accordingly. Always refer to the official tariff schedule for the precise duty calculation method.
What are the key classification criteria to ensure a machine is correctly classified under HS 845970?
HS code 845970 covers 'Other threading or tapping machines' that are not specifically covered by other headings within Chapter 84. The primary function of these machines must be the threading or tapping of materials, typically metals. This includes machines designed for creating internal threads (tapping) or external threads (threading). Key classification criteria include the machine's ability to perform these specific operations, its construction (e.g., whether it's a standalone machine or part of a larger system), and its intended use. Machines that perform other machining operations like drilling, milling, or grinding, even if they can also thread or tap, may be classified elsewhere if those other operations are their principal function. Consult the Explanatory Notes to the Harmonized System for detailed guidance.
What documentation is typically required for importing machines classified under HS 845970?
When importing machines under HS code 845970, standard import documentation is generally required. This includes a commercial invoice detailing the value, quantity, and description of the goods; a packing list; and a bill of lading or air waybill. Depending on the country of origin and destination, a certificate of origin may be necessary, especially if claiming preferential duty rates under a Free Trade Agreement (FTA). Importers may also need to provide technical specifications or brochures to substantiate the classification. Safety and compliance certifications, such as CE marking for the EU market or specific electrical safety certifications, might also be required. Always verify the specific import requirements with the customs authorities of the destination country.
Which common trade agreements offer preferential duty rates for HS code 845970, and how can importers verify eligibility?
Several trade agreements can provide preferential duty rates for HS code 845970. For instance, the United States has FTAs with countries like South Korea (US-Korea Free Trade Agreement), Australia (AUSFTA), and Chile (US-Chile FTA), which may offer reduced or zero duty rates for eligible goods originating from these countries. The European Union also has numerous trade agreements with third countries that could impact duties. To verify eligibility, importers must ensure the 'threading or tapping machine' is considered originating in the partner country according to the rules of origin stipulated in the specific trade agreement. This typically involves obtaining a certificate of origin from the exporter and confirming that the goods meet the required value content or tariff shift criteria. Consulting the official text of the relevant trade agreement and the customs regulations of the importing country is essential.
