Copper Transfer Pricing 2026: LME Price Adjustments | Income Tax

What Happened?

Transfer pricing authorities have increasingly scrutinized copper transfer pricing cases where Indian companies rely solely on London Metal Exchange (LME) published prices without adjusting for market-specific factors. As of September 2026, it is now well-established that LME benchmark prices alone are insufficient for determining arm's length prices under Section 92 of the Income Tax Act 2025. Taxpayers must make documented adjustments for quality variations, treatment and refining charges (TC/RC), freight costs, timing differences, and trader functions performed.

Background & Legal Context

Transfer Pricing Regulation Under Income Tax Act 2025

Section 92 of the Income Tax Act 2025 requires that international transactions between related parties must be priced at arm's length value—the price that would prevail between independent parties. For commodity transfers like copper, the Transfer Pricing Officer (TPO) typically benchmarks against published commodity exchange prices.

• Section 92(1): Defines international transaction and requires arm's length pricing
• Section 92C(5): Allows use of external comparable data, including commodity exchange rates
• Section 92E & 92F (AY 2025-26 onwards): Mandates transfer pricing documentation and functional analysis

Why LME Prices Need Adjustments

The LME publishes spot prices for grade-A copper cathodes of specific purity traded on the exchange. However, real-world copper transactions involve:

• Grade variations (purity, impurity levels)
• Treatment charges (smelting, refining costs)
• Refining charges (per-metric-ton deductions)
• Freight and logistics costs
• Time gaps between quotation date and actual delivery
• Trader margin and financing functions

The TPO has repeatedly held that companies cannot simply quote LME+X markup without economic justification for each component.

What Does This Mean for You?

For Copper Exporters & Importers

If your company transfers copper (or copper products) to/from related parties abroad, the TPO will now demand:

1. Quality Adjustment: If you export copper of lower purity than LME grade-A, you must reduce the benchmark price proportionally. Conversely, higher purity commands a premium. You need third-party quality certification.
2. TC/RC Documentation: Indian smelters and refiners incur treatment and refining charges. These are legitimate deductions from the LME price. You must provide invoices and market quotations proving the standard TC/RC for the grade supplied.
3. Freight & Insurance: The LME price is Ex-London (Delivery). If you deliver FOB or CIF, freight and insurance must be separately accounted and substantiated with shipping documents.
4. Quotation Period Mismatch: If the invoice date differs from the LME quotation date used, the TPO expects you to explain price movements and use the relevant LME rate for the invoice date (or average of 3-5 days).
5. Trader Functions: If a related party trader purchases from you and resells, the transfer price must reflect whether the trader assumed inventory risk, credit risk, and market risk. Simply marking up the LME price without economic substance will fail audit.

Practical Example for AY 2026-27

Case: ABC Ltd (India) exports 100 MT of copper cathode (97.5% purity) to ABC Ltd (Singapore) on 15 September 2026.

• LME Price on 15 Sep 2026: USD 10,000 per MT
• Quality Adjustment (for 97.5% vs 99.99% LME grade): -USD 150 per MT (with market evidence)
• TC/RC (treatment & refining cost): -USD 200 per MT (with industry quotations)
• Freight FOB to CIF conversion: +USD 300 per MT (with B/L proof)
• Adjusted Arm's Length Price: USD 9,950 per MT

If ABC Ltd simply invoiced at LME price (USD 10,000) without these adjustments, the TPO will disallow the difference during AY 2026-27 assessment and demand tax on the shortfall plus interest and penalty.

What Should You Do Now?

Immediate Action Items (For AY 2026-27 & AY 2027-28)

• Audit Your Transfer Pricing Policy: If you have an existing TP policy that cites "LME + margin," revise it immediately. Engage a TP specialist to quantify each adjustment component with supporting evidence.
• Gather Quality & Grade Documentation: Obtain third-party lab reports (Bureau of Indian Standards, NABL-accredited labs) certifying the copper grade, purity, and impurity levels. Keep these in your TP file.
• Source TC/RC Benchmarks: Collect quotations from independent smelters/refiners or use published industry data (e.g., Copper Development Association, industry journals) to justify treatment and refining charges deducted from LME.
• Document Freight Separately: Maintain shipping documents (Bills of Lading, freight invoices) showing that freight is not embedded in your transfer price but separately recovered from the related party or included in CIF pricing with clear delineation.
• Track Quotation Dates: Create a log of LME prices on invoice date, quotation date, and delivery date. If there is a gap, document the reason (e.g., standard 5-day credit period, supply chain practice) and use the appropriate LME rate.
• Prepare Functional Analysis: Under Section 92E & 92F, conduct a detailed functional analysis: What functions does the related party perform? Does it assume credit, inventory, or market risk? Adjust the transfer price to reflect these functions.
• Update TP Documentation (Form 3CEB, Schedule-FA): Ensure your transfer pricing documentation and Form 3CEB (if applicable) fully explain the adjustments and cite comparable uncontrolled prices or cost-plus margins for validation.

If You Face an Audit

If the TPO issues a notice under Section 92(3) (transfer pricing adjustment), respond promptly with:

• Complete TP working papers and benchmarking study
• All quality certificates and third-party valuation reports
• Market quotations for TC/RC (minimum 3-5 independent sources)
• Shipping invoices and freight contracts
• Functional analysis showing why the adjustment is justified

Do not dismiss the TPO's demand as routine; provide substantive economic evidence that your pricing methodology is sound and arm's length.

Key Takeaways

• LME Alone Is Not Arm's Length: Relying solely on published LME copper prices without adjustments is a high-risk transfer pricing strategy in AY 2026-27 onwards.
• Six Adjustments Are Critical: Quality, TC/RC, freight, timing, trader functions, and currency fluctuations must be separately identified and documented with third-party evidence.
• Section 92 Compliance Is Mandatory: Under Income Tax Act 2025, every international transaction requires transfer pricing documentation. Copper transfers are not exempt.
• Functional Analysis Determines Price: The transfer price must reflect the functions, assets, and risks assumed by the related party—a simple markup on LME is unlikely to survive TPO scrutiny.
• Documentation Is Your Defense: In disputes under Section 92(3), your contemporaneous transfer pricing file and third-party supporting documents are critical. Without these, penalties and interest can be substantial.
