Machines, parts and accessories of machines or auxiliary machinery, spindles, spindle flyers, spinning rings and ring travellers.
Classification of spinning rings under HS 8448.33
Spinning rings are essential components of textile machinery, specifically used in ring spinning frames to produce yarn. They are classified under HS code 8448.33. Chapter 84 covers nuclear reactors, boilers, machinery, and mechanical appliances. Heading 8448 is reserved for auxiliary machinery for use with the machines of headings 8444 to 8447, which include machines for extruding, drawing, or spinning man-made textile materials. Sub-heading 8448.33 specifically identifies parts and accessories of machines of heading 8445 or of their auxiliary machinery, explicitly naming spindles, spindle flyers, spinning rings, and ring travellers. The classification is based on the principle that parts dedicated solely or principally for use with a specific machine are classified with that machine or in a specific parts heading. Since spinning rings are specialized components that have no other function outside of the textile spinning process, they are precisely placed in this category. The material composition, whether hardened steel or sintered metal, does not change this classification as long as the item is recognizable as a part of a spinning machine.

Codes often confused with 8448.33
Common mistake. Spinning rings are frequently misclassified under 8445, which is the heading for the complete spinning machines themselves. However, according to the Section XVI notes, parts are generally classified in their own specific headings if available, making 8448.33 the correct choice. Another common error is using 7318, which covers general-purpose steel rings, screws, and bolts. Because spinning rings are highly specialized for textile production, they must be classified under the machinery parts heading rather than general hardware. Spindles, while often sold with rings, are also distinct but share the same sub-heading 8448.33.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
