Common types include nuts, bolts, screws, washers and rivets. Under GST, metal fasteners must be mapped to correct HSN codes so that purchase and sale entries are consistent. Traders of hardware, industrial supplies and engineering goods should understand fastener HSN codes clearly. ## Fastener HSN Code Classification and GST Rates Here are some commonly used HSN codes and GST rates for this category ### Section Classification | **Section No** | **Section Title** | **Section Description** | | --- | --- | --- | | [**15**](https://busy.in/hsn/section-15/) | Guide to HSN Section 15 | BASE METAL & ARTICLES OF BASE METAL | ### Chapter Classification | **Chapter No** | **Chapter Title** | **Chapter Description** | | --- | --- | --- | | [**73**](https://busy.in/hsn/chapter-73/) | Articles Made of Iron/Steel | Articles of iron or steel | | [**83**](https://busy.in/hsn/chapter-83/) | Miscellaneous Base Metal Articles | Miscellaneous articles of base metal | ### 4 Digit HSN Code Classification | **HSN Code** | **HSN Code Title** | **GST Rate** | | --- | --- | --- | | [**7318**](https://busy.in/hsn/sub-chapter-7318/) | Screws, Bolts, Nuts (Iron/Steel) | **18%** | | [**8308**](https://busy.in/hsn/sub-chapter-8308/) | Clasps & Buckles | **18%** | ### 8 Digit HSN Code Classification | **HSN Code** | **HSN Code Title** | **GST Rate** | | --- | --- | --- | | [**73181110**](https://busy.in/hsn/hsn-73181110/) | Threaded articles : Coach screws : Machine screws | **18%** | | [**73181190**](https://busy.in/hsn/hsn-73181190/) | Transmission apparatus: TV broadcast transmitter | **18%** | | [**73181200**](https://busy.in/hsn/hsn-73181200/) | Threaded Articles Wood Screws | **18%** | | [**73181300**](https://busy.in/hsn/hsn-73181300/) | Threaded articles : Screw hooks and screws | **18%** | | [**73181400**](https://busy.in/hsn/hsn-73181400/) | Threaded Articles \| Self-Tapping Screws | **18%** | | [**73181500**](https://busy.in/hsn/hsn-73181500/) | Threaded articles : Other screws and bolts | **18%** | | [**73181600**](https://busy.in/hsn/hsn-73181600/) | Threaded Articles \| Nuts | **18%** | | [**73181900**](https://busy.in/hsn/hsn-73181900/) | Threaded Articles | **18%** | | [**73182100**](https://busy.in/hsn/hsn-73182100/) | Non-threaded: Spring lock washers | **18%** | | [**73182200**](https://busy.in/hsn/hsn-73182200/) | Non-Threaded Articles \| Other Washers | **18%** | | [**73182300**](https://busy.in/hsn/hsn-73182300/) | Non-Threaded Articles \| Rivets | **18%** | | [**73182400**](https://busy.in/hsn/hsn-73182400/) | Non-threaded articles : Cotters and cotter-pins | **18%** | | [**73182910**](https://busy.in/hsn/hsn-73182910/) | Natural Calcium Borates And Concentrates | **18%** | | [**73182990**](https://busy.in/hsn/hsn-73182990/) | Non-Threaded Articles | **18%** | | [**83081010**](https://busy.in/hsn/hsn-83081010/) | High Tenacity Yarn Of Polyesters \| Other | **18%** | | [**83081021**](https://busy.in/hsn/hsn-83081021/) | Hooks, eyes and eyelets : Eyelets : For footwear | **18%** | | [**83081029**](https://busy.in/hsn/hsn-83081029/) | Hooks, Eyes And Eyelets\| Eyelets | **18%** | | [**83082000**](https://busy.in/hsn/hsn-83082000/) | Tubular Or Bifurcated Rivets | **18%** | | [**83089011**](https://busy.in/hsn/hsn-83089011/) | Other, including parts : Buckles : For footwear | **18%** | | [**83089019**](https://busy.in/hsn/hsn-83089019/) | Other: Activated natural mineral products: Other | **18%** | | [**83089020**](https://busy.in/hsn/hsn-83089020/) | Other, including parts : Imitation zari spangles | **18%** | | [**83089031**](https://busy.in/hsn/hsn-83089031/) | Base Metal Beads/Spangles | **18%** | | [**83089039**](https://busy.in/hsn/hsn-83089039/) | Beads and spangles: Other | **18%** | | [**83089040**](https://busy.in/hsn/hsn-83089040/) | Fittings for Travel Requisites & Leather Goods | **18%** | | [**83089091**](https://busy.in/hsn/hsn-83089091/) | Other Garment/Leather/Plastic Fasteners | **18%** | | [**83089099**](https://busy.in/hsn/hsn-83089099/) | Other, including parts : Other : Other | **18%** | \* GST rates may vary based on the latest GST notifications ## How Metal Fasteners Are Classified under HSN? Metal fasteners are grouped based on: - Their function of fastening or joining parts - Their construction, such as threaded or non threaded - Their base material, usually iron or steel Examples: - Hex bolts, foundation bolts, anchor bolts - Hex nuts, lock nuts, dome nuts - Plain washers, spring washers All these are grouped together in the main fastener heading. The HSN distinguishes them from other small hardware items that are not fasteners. ## The HSN Code for Industrial Fasteners Industrial fasteners used in heavy machinery, bridges, or large structures may be of special grades, coatings, or high strength classes. However, their basic nature as bolts, nuts, or screws keeps them in the same fastener heading. Only when a fastener becomes a very special part of a machine with unique design might the classification shift. For normal trade, standard fastener HSN is followed. ## Types of Fasteners and Their HSN Code Classification Common types of fasteners include: - Bolts and nuts - Screws and machine screws - Washers and circlips - Rivets and pins These are all mapped to the same broad fastener heading if made of iron or steel. Fasteners made from plastic or aluminium may be classified under other material specific headings. ## About the author **Hitesh Aggarwal** As a Chartered Accountant with over 12 years of experience, I am not only skilled in my profession but also passionate about writing.

Metal fasteners like iron or steel screws, bolts, nuts and washers are usually classified under the 7318 HSN group. ### Are industrial fasteners classified separately from other fasteners under HSN? No. As long as they are bolts, nuts, screws or similar items, they remain in the same heading, even if used in heavy industrial applications. ### How does GST apply to fastener products? Fasteners are industrial goods and usually attract a standard GST rate. The exact rate is notified in the GST rate schedule. ### Can the material of the fastener affect its HSN code classification? Yes. Fasteners made of plastic, aluminium, or copper may fall under different headings related to those materials. Iron and steel fasteners remain in the 7318 family. ### How are fasteners used in automotive vs construction industries categorized under HSN? Usage in automotive or construction does not normally change the HSN. The classification depends on the product type and material, not its end use. ## Related articles - [Watch HSN Code: Classification for Wrist Watches, Smart Watches & Wall Clocks](https://busy.in/hsn/watch-hsn-code/) - [Tissue Paper HSN Code: Classification for Facial Tissues & Tissue Napkins](https://busy.in/hsn/tissue-paper-hsn-code/) - [Software HSN Code: Classification for Application and Computer Software](https://busy.in/hsn/software-hsn-code/) - [Safety Helmet HSN Code - Classification for Construction and Industrial Helmets](https://busy.in/hsn/safety-helmet-hsn-code/) - [RAM HSN Code: Classification for Laptop, Computer and DDR4 RAM](https://busy.in/hsn/ram-hsn-code/) - [Pumps HSN Code - Classification for Water and Electric Pumps](https://busy.in/hsn/pumps-hsn-code/) - [Pulses HSN Code: Classification for Chana Dal and Toor Dal](https://busy.in/hsn/pulses-hsn-code/) - [Pillar Cock HSN Code: Classification for Brass Pillar Cocks](https://busy.in/hsn/pillar-cock-hsn-code/) - [Phenyl HSN Code: Classification for White and Black Phenyl](https://busy.in/hsn/phenyl-hsn-code/) - [Manpower Supply HSN Code: Classification for Labour and Skilled Services](https://busy.in/hsn/manpower-supply-hsn-code/)
