Clamp HSN Code: Classification for Hose, Pipe & Metal Clamps
Clamps are small but important hardware items that hold pipes, hoses, cables and other parts in place. They are widely used in plumbing, automotive, construction and machinery. Under GST, clamps are classified under specific HSN codes based on the material and type, such as hose clamps, pipe clamps and other metal clamps.
HSN Code and GST Rate for Clamp Products
| Clamp type | Typical HSN code | Typical GST rate |
|---|---|---|
| Steel or iron hose clamps | 7326 | 18% |
| Steel or iron pipe clamps | 7326 | 18% |
| Other metal clamps and brackets | 7326 | 18% |
| Clamps made of other base metals | Other Chapter 73 or 76/79 headings | 18% |
Note: Most iron and steel clamps are grouped under HSN 7326 as other articles of iron or steel. However, clamps made of aluminium, copper or other metals may shift to other headings. Always check the exact tariff entry and latest GST notifications before finalising the code.
What Is the HSN Code for Clamps?
For many common hose and pipe clamps made of iron or steel, the usual HSN classification is 7326. This heading covers other articles of iron or steel that are not covered more specifically elsewhere in Chapter 73. It is widely used in trade invoices for general metal clamps and brackets.
If the clamp is designed as a specialised pipe fitting, it may sometimes be considered under tube or pipe fitting headings. But in day to day billing practice, most normal screw type or band type hose clamps fall under the general article heading 7326.
How Hose and Pipe Clamps Are Classified under HSN
Hose clamps that are used to secure rubber or plastic hoses to pipes, nipples or fittings are generally classified as other articles of iron or steel under HSN 7326 when they are made of steel. Pipe clamps that hold pipes against walls or supports are also usually billed under the same heading when made from iron or steel strips and fasteners.
For clamps made from stainless steel, the classification still often remains under Chapter 73, but the exact sub heading may change depending on the detailed tariff. Suppliers should describe whether the clamp is for hose, pipe or structural support to help determine the proper HSN code.
The HSN Code for Metal Clamps
Metal clamps made from iron or steel are most commonly treated under HSN 7326. When clamps are made from aluminium or other base metals, the classification can shift to headings for other articles of that specific metal, such as 7616 for aluminium articles. The main principle is to classify the clamp as an article of the base metal from which it is made.
In industries like automotive and machinery, clamps can be part of larger assemblies. If the clamp is imported or supplied as part of a complete set, the whole kit may be classified under the heading for the main function of the set rather than as a separate clamp.
GST on Clamp Products
Clamps made from iron, steel or other base metals generally attract GST at 18%. This standard rate applies on the invoice value for B2B as well as B2C supplies. Businesses can claim input tax credit on clamps that are used in the course of business, such as in plant maintenance, pipe installations or machinery assembly.
Adjustable clamps, fixed clamps, U clamps and saddle clamps are normally taxed at the same 18% rate. The use of the clamp in different industries, such as plumbing, construction or automotive, does not usually change the HSN code, but it can appear in the product description for clarity.

Frequently Asked Questions
-
What is the HSN code for hose clamps?
Hose clamps made of iron or steel are usually classified under HSN 7326 as other articles of iron or steel. This heading is commonly used in invoices for band type and screw type hose clamps.
-
Are pipe clamps classified separately under HSN?
Pipe clamps are normally kept under the same heading 7326 when they are simple metal brackets or support clamps. Only highly specialised fittings may move to a different pipe fitting heading.
-
How does GST apply to metal clamps?
Metal clamps are generally taxed at 18% GST. Registered buyers can claim input tax credit on eligible clamp purchases that are used for business purposes.
-
Can clamps used in different industries have different HSN codes?
The industry of use, such as automotive or plumbing, does not normally change the HSN code. However, if the clamp becomes part of a specific machine or apparatus, the classification may move to the heading for that machine or set.
-
Are adjustable and fixed clamps categorized separately under HSN?
Adjustable and fixed clamps made from similar base metals are usually classified under the same HSN heading, such as 7326 for iron and steel. Differences in design are shown in the description, not by changing the chapter heading.
