Product classification
HS code for Copper nuts: 7415.33
Copper, screws, bolts and nuts, threaded.
Classification of copper nuts under HS 7415.33
Copper nuts are classified under HS code 7415.33. This classification is part of Heading 7415, which covers a wide range of copper fasteners, including nails, tacks, drawing pins, staples, and similar articles. Subheading 7415.33 specifically identifies threaded screws, bolts, and nuts. The classification is based on the fact that these items are made of copper and are threaded fasteners. Even if the nuts are made of copper alloys such as brass, they remain within this heading as Chapter 74 covers both refined copper and copper alloys. The distinction between threaded and non-threaded fasteners is crucial here, as non-threaded items like washers or rivets fall under different subheadings within 7415. The material composition is the primary driver for this classification, as fasteners made of other metals like iron or steel are excluded from Chapter 74.

Codes often confused with 7415.33
Common mistake. The most common misclassification occurs with HS code 7318, which covers screws, bolts, and nuts made of iron or steel. Another frequent error is using 7415.21, which is reserved for non-threaded washers of copper. If the nut is part of a specific machinery assembly and is imported as a kit, some may mistakenly try to classify it under the machinery's heading in Chapter 84, but fasteners are generally classified by material under GRI 1.

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).
