GST on Warranty Replacement Supplies for Auto Components: FOC Supply and Schedule I

A Tier-1 brake-pad supplier in Pune opens its monthly warranty review at 11:00 IST. The dispatch ledger shows 1,520 warranty replacements processed in the last month against the Mahindra XUV programme — a 0.8% warranty rate on the 190,000 brake-pad sets shipped. The replacement-part value, costed at the supplier’s standard cost, is ₹3.2 lakh for the month and ₹38 lakh on a trailing-twelve basis. The CFO has three questions on the desk. First, the dispatch ledger shows 23 of the 1,520 replacements were raised as zero-value tax invoices instead of Rule 55 delivery challans — does that classification matter for audit. Second, the production-cost engineer has noted that ₹38 lakh of warranty stock comes out of the same manufacturing line as the paid production, and the controller asks whether the proportionate input ITC should be reversed under Rule 42. Third, the OEM has just initiated a paid-warranty extension programme on the same XUV line — and a portion of next quarter’s warranty claims will be paid replacements at agreed prices, not supplier-borne. GST warranty replacement FOC supply auto component India is one of the cleanest CBIC circular positions on the books, but the operational classification at dispatch is where the audit finding lands.

Quick reference

What CBIC Circular 195/07/2022 actually settled

Before July 2022 the position on warranty replacements in Indian auto-component supply chains was unsettled. Some field GST officers were treating free-of-charge warranty replacements as Schedule I deemed supplies — particularly where the supplier and the OEM had any common-director or supplier-development relationship that might be argued to bring them within Section 15. Others were treating the replacement as a non-supply but demanding proportionate Rule 42 ITC reversal on the inputs used to manufacture the warranty stock. Neither position was fully comfortable for industry: the first created phantom output tax; the second created phantom input tax leakage. The aggregate exposure for high-warranty-rate sub-categories like brake-pads, electronic control units and friction parts was material enough that the Society of Indian Automobile Manufacturers (SIAM) and the Automotive Component Manufacturers Association (ACMA) jointly approached the GST Council for clarification.

CBIC Circular 195/07/2022 dated 17 July 2022 closed both ambiguities. Paragraph 2 reads, in operational terms, that where a supplier replaces parts during the warranty period free of cost, no GST is payable on such replacement because the consideration for the replacement was already received and GST paid on the original sale. Paragraph 3 reads that the supplier does not need to reverse ITC on the inputs used to manufacture the warranty replacement because the original sale on which GST was paid is the supply against which the inputs are deployed. The two paragraphs together settle the supplier-borne warranty pattern that accounts for 92% to 95% of Indian auto-component warranty volume.

The remaining 5% to 8% is the paid-warranty programme — where the OEM pays the supplier separately for the replacement, either because the original warranty has lapsed and a paid-warranty extension is in force, or because the failure mode is outside the warranty terms and the OEM purchases the replacement at an agreed price. For those cases the circular does not apply: the replacement is a fresh supply, GST is charged at the standard part rate, and the supplier raises a Section 31 tax invoice in the normal course.

How the classification at dispatch decides the GST position

The operational reality at a Tier-1 warranty dispatch desk is that the classification has to happen at the moment the parts leave the plant. Get it right and the documentation chain runs cleanly through GSTR-9. Get it wrong and the position is hard to retrofit.

The decision tree:

Step 1 — Is the original sale invoice retrievable? The supplier’s warranty-claim register must tie the replacement to the original sale invoice number and date. If the original sale invoice is more than the warranty period old (typically 2 years for brake-pads, 3 years for ECUs, 5 years for some structural parts), the warranty position is closed and the replacement cannot be supplier-borne. If the original sale is inside the warranty window, proceed.

Step 2 — Is the OEM paying the supplier for the replacement? If yes, paid-replacement path: raise Section 31 tax invoice, charge GST at standard rate. If no, supplier-borne path: proceed.

Step 3 — Is the failure mode within warranty terms? If yes, supplier-borne path with full circular protection. If no, the position is paid-replacement even if the OEM has not yet agreed to pay — the supplier raises a tax invoice at the agreed paid-replacement price; if the OEM later disputes and the supplier writes off the receivable, a Section 34 credit note flows through.

Step 4 — Issue documentation. For supplier-borne: Rule 55 delivery challan with explicit warranty replacement against invoice number and date in the description field, zero taxable value, no GST. For paid-replacement: Section 31 tax invoice at the agreed consideration, GST at standard rate.

The single most common audit finding in this space is misclassification at Step 2 — the supplier dispatches as supplier-borne (no GST) but the OEM later debits the supplier through a back-charge mechanism that effectively converts the transaction into a paid-replacement. The audit position then is that GST should have been charged at dispatch and the supplier carries a retrospective output-tax exposure. The full FOMP back-charge mechanic that creates this confusion is dissected in FOMP warranty back-charge accounting for auto components.

The Rule 42 ITC preservation argument and why it matters

For a brake-pad Tier-1 making 190,000 brake-pad sets per month at a 0.8% warranty rate, the warranty stock consumes roughly 1,520 sets of monthly production. At a standard cost of ₹210 per set, that is ₹3.2 lakh of input value consumed for warranty. The inputs — friction material, backing plate, bonding agents — carry GST at 18% which translates to roughly ₹57,600 of input ITC attributable to the warranty production run.

If Rule 42 reversal had to apply (the pre-circular position), the supplier would reverse ₹57,600 every month — ₹6.9 lakh per year on this one programme alone. Across a typical Tier-1 portfolio of 6 to 8 active OEM programmes, the aggregate annual reversal exposure would have been ₹35 to ₹50 lakh. CBIC Circular 195/07/2022 paragraph 3 eliminates that exposure entirely.

The audit defence file for the circular position has three documents: the dispatch ledger showing the supplier-borne classification, the warranty-claim register tying the replacement to the original sale invoice, and the production-cost analysis showing the input-ITC traced to the warranty production run. The third is the document most often missing at audit — the supplier knows the warranty rate but has not formally documented the input-ITC quantum attributable to warranty production. Building this document on a forward basis (rather than retrospectively at audit) is one of the operating disciplines that mid-sized Tier-1s typically have to build out after their first GST audit cycle.

Worked example — Mahindra XUV brake-pad programme, 2-year warranty

A Pune Tier-1 supplying brake-pad sets to the Mahindra XUV programme operates a 2-year warranty on the dispatched sets. The full mechanics:

• Monthly XUV brake-pad shipment: 190,000 sets at ₹860 each (per-set price including all amortisation). Monthly invoiced value: ₹16.34 crore. GST at 18%: ₹2.94 crore. Total invoiced: ₹19.28 crore. The supplier discharges the ₹2.94 crore output tax in the GSTR-3B of dispatch month.
• Warranty rate: 0.8% on a 2-year window — captured cumulatively across 24 months.
• Monthly warranty replacement dispatches: 1,520 sets (the 0.8% applied to current-month roll-back is operationally lumpy month-to-month, but averages 1,520).
• Per-set replacement cost at standard cost: ₹210 (a brake-pad costs less than its full sales price; the ₹860 carries margin, tooling amortisation, programme overhead).
• Monthly warranty stock value: ₹3.2 lakh. Trailing-12 months: ₹38.4 lakh.
• GST on dispatch (supplier-borne path): zero. The replacement parts go out on Rule 55 delivery challans with warranty replacement against invoice number and date narration.
• Input ITC on the warranty production run: roughly ₹57,600 per month at 18% on the ₹3.2 lakh input cost. Under CBIC Circular 195/07/2022 paragraph 3, this ITC is preserved.

Now the paid-warranty programme overlay. In month 13 of the operating year, Mahindra launches a paid extended-warranty programme on the XUV line that extends the warranty window from 24 months to 36 months at a paid-replacement price of ₹260 per set for the extension period. The supplier’s classification logic now has to split:

• Warranty claims tied to original sales inside the original 24-month window: supplier-borne, no GST, no ITC reversal.
• Warranty claims tied to original sales between months 25 and 36 of the original sale window (under the new paid extension): paid-replacement at ₹260 per set, full GST at 18%.

The split is mechanically driven by the original sale date stamped on the warranty claim. At a typical operating split of 70% supplier-borne and 30% paid-replacement once the extension is live, the supplier’s monthly mix becomes 1,064 supplier-borne replacements (₹2.24 lakh cost, no GST output) and 456 paid replacements (₹1.19 lakh revenue, ₹21,400 GST output).

The reconciliation requirement: the warranty-claim register must carry an original-sale-date field on every claim, and the dispatch workflow must classify on that field. A claim against an original sale dated 1 February 2024 against the original warranty programme is supplier-borne. A claim against an original sale dated 1 March 2024 against the paid extension programme (where the extension was purchased on day 730) is paid-replacement.

Single source of failure: if the original-sale-date field is missing on the warranty claim or the warranty-programme-type field is missing on the original sale, the dispatch desk defaults to the simpler classification and the audit finding lands.

Tax overlay — TDS and TCS adjacencies

The GST warranty position is one leg. The TDS and TCS legs:

• Section 393(1)(j), payment code 1011 — TDS by the OEM on paid-warranty service payments to the supplier at 2% (services contract under the new Section 393 code 1011 replacing legacy Section 194C from 1 April 2026). Applies only to the paid-replacement leg; supplier-borne replacements do not carry a payment from the OEM to deduct on.
• Section 393(1)(k), payment code 1012 — TDS by the supplier on inputs procured for warranty stock at 0.1% on aggregate purchases above ₹50 lakh per FY from any single seller. Same mechanic as for production stock; warranty production is not separately treated.
• GST law is unchanged by the Income Tax Act 2025. CBIC Circular 195/07/2022 continues to govern. The cross-era reconciliation between legacy 194C entries in Form 26AS for FY 2025-26 and the new 1011 code is in Form 26AS reconciliation for auto-component suppliers.

How does the warranty position interact with GSTR-9?

Three things must tie at year-end:

• GSTR-3B Table 4 — outward supplies on Mahindra dispatches at full GST; warranty dispatches do not appear because they are non-supplies.
• GSTR-9 Table 4 and Table 5 — outward supplies reconciled to dispatch ledger; warranty replacements need a parallel disclosure note showing the non-supply position and the CBIC Circular 195/07/2022 reliance.
• Supplier’s dispatch and warranty registers — every Rule 55 warranty challan tied back to the original sale invoice.
