MCB HSN Code and GST Rate in India: Classification and Invoice Rules

No. A complete electrical control panel does not automatically use the MCB HSN code of a breaker fitted inside it. Heading 8537 covers specified boards, panels, consoles, desks, cabinets and other bases equipped with two or more apparatus of heading 8535 or 8536 for electrical control or distribution.

For example, an electrical contractor may purchase loose MCBs for stock and later assemble them into a distribution panel. The loose breaker and the completed panel are separate supplies for classification purposes. The product specifications, assembly and customer-facing supply should determine the MCB HSN code or other classification used on the invoice.

Calculate GST by applying the verified rate to the taxable value of the MCB supply. For an illustrative taxable value of Rs. 10,000 at 18% GST, the GST amount is Rs. 1,800 and the invoice total is Rs. 11,800.

• Taxable value: Rs. 10,000
• GST at 18%: Rs. 1,800
• Illustrative invoice total: Rs. 11,800

This example assumes Rs. 10,000 is the complete taxable value and no adjustment changes it. The actual invoice must reflect the applicable central and state GST or integrated GST treatment.

The HSN digits required on a GST tax invoice depend on the supplier’s aggregate turnover in the preceding financial year. The requirements introduced through Notification No. 78/2020–Central Tax apply from 1 April 2021.

• Aggregate turnover up to Rs. 5 crore in the preceding financial year: four HSN digits are generally required on applicable tax invoices.
• Aggregate turnover above Rs. 5 crore in the preceding financial year: six HSN digits are generally required.

A registered supplier with preceding-year aggregate turnover up to Rs. 5 crore may omit the specified HSN digits on an invoice for a supply to an unregistered person, subject to the applicable rule. This invoice exception does not remove separate HSN reporting requirements where those apply in GST returns.

Use the product specifications and tariff description together rather than relying on a product name or online search result when checking the MCB HSN code. 

A practical classification check can follow these steps:

• Identify whether the supply is a standalone automatic circuit breaker, a complete panel or a separately supplied part.
• Check the rated voltage and the device’s actual switching or protection function.
• Compare the product with the relevant Chapter 85 heading and tariff description.
• Confirm the detailed Indian tariff entry needed for the transaction.
• Check the applicable GST rate notification and invoice HSN requirement before issuing the tax invoice.

Keep the product specification, purchase description, sales description and invoice consistent. If the goods could reasonably fall under more than one entry, resolve the classification before charging GST.

The most common errors arise when businesses classify a product from its commercial name rather than its technical characteristics.

• Using 853620 for every product marketed as an MCB without checking voltage and function.
• Copying the code of a loose breaker onto a complete control panel.
• Confusing the four-digit heading 8536 with the more detailed six-digit subheading 853620.
• Treating the GST rate as proof of classification rather than checking both separately.
• Using the wrong number of HSN digits on a GST invoice based on current-year rather than preceding-year aggregate turnover.

A documented MCB HSN code classification check is particularly useful for manufacturers, distributors and panel assemblers handling multiple electrical products.

An MCB distributor may pay suppliers for breaker stock before receiving payment from installers or retailers. A panel assembler may also need enclosures, components, testing equipment and other operating inputs, creating a timing gap between business outflows and customer receipts.

Once the business has estimated its stock or equipment requirement and expected cash receipts, a business can consider a Bajaj Finance Business Loan for permitted business requirements. It offers loan amounts ranging from Rs. 2 lakh to Rs. 80 lakh, with repayment tenures from 12 months to 96 months and business loan interest rates from 14% to 23.50% per annum, subject to business loan eligibility and applicable terms.

Compare the full borrowing cost, including applicable charges, with expected customer receipts before deciding how much funding the business needs.
