How to Classify This HS Code?
What products does HS 844831 cover?
This subheading covers parts and accessories specifically designed for machines of heading 8445, which are used for preparing textile fibers or for spinning textile fibers, and for their auxiliary machinery. According to the World Customs Organization (WCO) Harmonized System Explanatory Notes and definitions found in official tariff schedules like the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC, this includes components such as needles, shuttles, bobbins, and specialized tools integral to the operation of carding, combing, drawing, and spinning machines, as well as their supporting equipment.
What falls outside HS 844831?
The following products are excluded from HS 844831: general-purpose tools or machinery parts not exclusively for heading 8445 machines, such as standard wrenches or generic fasteners, unless specifically designed for these textile machines. Also excluded are finished textile machines themselves (classified under heading 8445), spare parts for other machinery within Chapter 84 not related to textile fiber preparation or spinning, and items like lubricants or cleaning agents, which are typically classified in other headings based on their composition or function.
What are common classification mistakes for HS 844831?
A common error is misclassifying parts that are not exclusively for heading 8445 machines, or classifying general-purpose components as specialized accessories. For instance, a standard bearing might be incorrectly classified here if it is not specifically manufactured and marketed for a textile spinning machine. This often arises from not adhering to 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, and if not otherwise restricted, according to GRI 6 for subheading classification.
How should importers classify products under HS 844831?

It is crucial to verify that the part or accessory is indeed intended for and compatible with machines covered by heading 8445, and not a more general component or a part for a different type of textile machinery.
How is the duty calculated for products under HS 844831?
A shipment of 500 specialized spinning ring holders, weighing 10 kilograms and declared at a customs value of $2,500 USD, would attract a US duty of $137.50. This is calculated using the Most Favored Nation (MFN) duty rate of 5.5% ad valorem, applied to the declared value: 5.5% × $2,500 = $137.50.
