Product classification
HS code for Chain links: 7315.90
Chain, parts n.e.c. in heading no. 7315, of iron or steel.
Classification of chain links under HS 7315.90
Chain links are classified under HS code 7315.90 because they are specifically identified as parts of chains made of iron or steel. According to the Harmonized System's General Rules of Interpretation (GRI), specifically Rule 1 and Rule 6, products are classified according to the terms of the headings and subheadings. Heading 7315 covers "Chain and parts thereof, of iron or steel." Since these links are not complete chains but are essential components, they fall into the "parts" category under subheading 7315.90. This classification applies to links for various types of chains, including articulated link chains, roller chains, and welded link chains. The material composition is a primary factor; the links must be made of iron or steel. If the links were made of copper or aluminum, they would be classified in their respective chapters, such as Chapter 74 or 76. Furthermore, the links must be recognizable as parts of chains. If they are general-purpose rings or loops that could be used for other applications, they might be classified elsewhere. The technical distinction between a part and a finished product is crucial here. A single link cannot perform the function of a chain, which is to transmit power or secure an object, thus it is classified as a part. The classification also considers the manufacturing process, such as whether the links are forged, cast, or stamped. Under the Explanatory Notes to the Harmonized System, parts of chains are classified here provided they are not more specifically included in other headings.

Codes often confused with 7315.90
Common mistake. Chain links are frequently misclassified under HS code 7315.11, which is reserved for fully assembled articulated link chains. The distinction lies in whether the item is a discrete part or a functional assembly. Another common error is using 7326.90, which is a residual category for other articles of iron or steel. However, because 7315 specifically mentions "parts" of chains, GRI 1 dictates that the more specific heading must be used. Additionally, links for conveyor belts might be confused with 8431.39, but if they are essentially chain links, 7315.90 remains the primary classification unless they are so specialized that they lose their identity as chain parts.
Top exporters and importers of HS 731590 (the code used for chain links), 2025
In 2025, the largest exporter of HS 731590 (the code used for chain links) in UN Comtrade data was Germany, with 20% of world exports; the largest importer in UN Comtrade data was the United States, with 16% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).

Questions about chain links
What is the HS code for Chain links?
The HS code for Chain links is 731590 (Chain; parts n.e.c. in heading no. 7315, of iron or steel). The HS code for chain links made of iron or steel is 7315.90. This code specifically covers parts of chains that are not yet assembled into a finished length of chain. It is important to verify the material, as links made of other metals like aluminum or copper would fall under different chapters entirely.
How do I classify Chain links for customs?
Chain links is classified under HS code 731590 — Chain; parts n.e.c. in heading no. 7315, of iron or steel. This is a 6-digit subheading level code.
Can these links be used for jewelry?
No, if the links are intended for use in jewelry or are made of precious metals, they are classified under Chapter 71. HS code 7315.90 is strictly for industrial or general-purpose iron and steel chain parts. Jewelry components are subject to different valuation and regulatory requirements than industrial hardware.
Which countries are the top exporters of chain links (HS 731590)?
