Choosing Transfer Pricing Methods: The Bock Compressors Ruling

Introduction: When the Method Becomes the Message

Which transfer pricing method is “most appropriate”? In international tax, that debate looks technical, a job for economists and policy wonks. But the method you pick, or the one you reject, says more than that. It shows the tax authority how it reads your business model, your value chain and your intent.

The point came up sharply in Bock Compressors India Pvt. Ltd. vs. DCIT. There, the Ahmedabad Bench of the Income Tax Appellate Tribunal (ITAT) took a firm stand on one method: the Resale Price Method (RPM).

The ruling did more than settle a debate about method. It restated a basic rule: for a trading entity that buys and sells goods, where the purchase and the sale form one economic whole, RPM comes first. It should not be set aside.

The case is a win for the taxpayer. It is also a lesson for any multinational group in India. How you pick a method, how you set out the facts, and how well you know the functions can change the whole shape of a transfer pricing dispute.

The Case in Brief: A Trading Business, a Method Rejected

Bock Compressors India is a subsidiary that trades at wholesale and retail. It used the Resale Price Method (RPM) to benchmark its international deals, which covered both the purchase and the resale of goods. The business was largely that of a distributor. It imported goods from related parties and sold them on in the Indian market, with little value added.

The Transfer Pricing Officer (TPO) rejected RPM and used the Transactional Net Margin Method (TNMM) instead. Why? The company spent a lot in India, on advertising and other running costs, and the TPO said that spend meant the resale was not a “simple resale”. The Dispute Resolution Panel (DRP) agreed, and the TPO made a large adjustment.

But on appeal, the Tribunal saw things differently. And that’s where the story gets interesting.

Dissecting the ITAT Ruling: Where the Logic Resides

The Tribunal did not side with RPM out of any box-ticking. It looked at the economic substance of the deals.

The Tribunal found that the purchase and the resale were inter-linked and inter-dependent: one continuous trading cycle. The company did not change or add to the goods in any real way. It moved them from related suppliers to end customers in India.

The profit driver was therefore not value-added services or unique intangibles. It was the gross margin on resale, and RPM is built to test exactly that.

More importantly, the Tribunal observed that:

“This is not a case of complex operations requiring deep functional analysis; it is a case where the sale of goods is routine, repeated, and economically standardised... making RPM not only acceptable but the most appropriate method.”

That clarity matters. In transfer pricing, the method you choose sets the rest. It sets how margins are worked out, how risks are judged, and how you explain any gap. Force the wrong method onto a case and the result can go badly wrong.

Why This Matters: The Real-World Implications

The ruling carries weight beyond the relief it gave the taxpayer. It rests on points that matter to any multinational group that buys and sells goods with its own group companies:

1. RPM is Not Inferior to TNMM—It's Contextual

Indian tax authorities often fall back on TNMM as a “catch-all” method, trading cases included. The ITAT says RPM should not be pushed aside just because the taxpayer spent money in India. What makes a method fit is the business model, not the expense sheet.

2. Aggregation of Transactions Matters

In Bock, the Tribunal accepted that the purchase leg and the sale leg formed one trade arrangement, not two separate arms. The principle follows: where the economics support it, linked deals can be grouped for benchmarking.

3. Functional Analysis Must Lead, Not Follow

Comparability of functions should drive the choice of method, not the other way round. The taxpayer showed that it did not carry out major development, enhancement, maintenance, protection or exploitation (DEMPE) functions. On those facts, a net margin test made little sense.

Wider Signals to Industry and Revenue Authorities

The decision turns on its own facts. Even so, it sits within a growing body of Indian transfer pricing case law in which courts push back on default adjustments that rest on loose assumptions.

For revenue authorities, the point is that the choice of method is not a matter of taste. It is a question of fact, set by the functions, risks and assets in the case.

For companies, the point is just as plain. If your model is that of a limited-risk distributor, and if your transfer pricing documentation backs RPM with credible comparables and steady gross margins, then defend it early, and defend it firmly.

Conclusion: More Than a Method, It's a Mindset

The Bock Compressors ruling may look like a footnote among the long records of transfer pricing litigation. It is not. In backing the taxpayer's RPM approach, the Tribunal held that substance beats standardisation, and that it is functions, not administrative ease, that should shape an assessment.

Method selection will stay a battleground as tax enforcement grows. This case shows what a business can do when it stays true to its economic model and backs it with facts, not formulas: it can ask for fair treatment, and expect it.

After all, transfer pricing isn’t just about numbers—it’s about narratives grounded in commercial reality.

Are your transfer pricing methods aligned with your actual business model, or just fitted to tax expectations? As scrutiny grows, that gap could decide your next audit, or your next win.
