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.
