Winning Appeal Strategy: Refuting Rubber Export Transfer Pricing Corrections Using the Resale Price Method

Transfer Pricing Litigation Analysis: Refuting Internal CUP Methods Over Commodity Export Volume Discrepancies

The transfer pricing dispute over the export of SIR 10 crumb rubber became the focal point in the case between PT TSS and the tax authority. The issue began when the Respondent issued a VAT export base (DPP) correction for the May 2019 period amounting to IDR 407,275,326.00, which stemmed from a transfer pricing adjustment in Corporate Income Tax. The tax authority believed that the export price to the Singaporean affiliate, ART Pte. Ltd., was below arm's length when compared to sales to an independent party (Bridgestone).

The Conflict: Rigid Premium Alignment vs. The Economic Realities of Scale in Related-Party Supply Chains

The litigation of this export revenue adjustment exposes a recurrent methodology flaw—the tax authority’s tendency to apply simplified pricing metrics without adjusting for massive volume gaps and international distribution roles:

• Respondent's Approach (DGT): The core of the conflict lay in the differing methodologies for determining the arm's length price. The Respondent utilized the Internal Comparable Uncontrolled Price (CUP) method by adding a 4.5 USCents per kilogram premium to the SICOM price formula, based on data from the Petitioner's transactions with Bridgestone. The fiscal authority operated on the oversimplified assumption that since both channels handled identical SIR 10 crumb rubber, the premium rates must be perfectly aligned under the arm's length principle.
• Appellant's Defense (PT TSS): Conversely, the Petitioner argued that the transactions with ART had significantly larger volumes (84.81% of total production) compared to Bridgestone (only 15.19%). The Petitioner emphasized that ART functioned as a trader entitled to fair remuneration, and the prices ART charged to end customers were valid market prices. The exporter maintained that a massive volume commitment (nearly 85% of total supply) naturally qualifies for a significant volume discount, making a micro-volume spot buyer (15.19%) an economically invalid direct baseline.

Judicial Review: Validating Flash-Title Logistics, Interquartile Ranges, and Economic Substance

The Tax Court Bench completely overturned the DGT’s transfer pricing adjustment, vindicating the taxpayer's pricing model based on the following international tax grounds:

1. Economic Validation of Flash-Title and Drop-Shipping Logistics: The Board of Judges, in its legal consideration, carefully examined the economic substance of these flash-title transactions. The judges found that although the goods were shipped directly from the Petitioner’s factory to end customers, ART bore the marketing risks and functions. The court recognized that direct physical routing (*drop-shipping*) to optimize maritime freight costs does not eliminate the legal liabilities, contract management, and commercial underwriting risks borne by the Singaporean mid-stream entity.
2. Rejection of the DGT Premium Scheme in Favor of RPM Testing: Instead of following the Respondent’s premium scheme, the Board shifted to testing the fairness of the margin received by ART as a trader using the Resale Price Method (RPM). The analysis showed that the 0.6% discount or margin enjoyed by ART fell within the industry's arm's length range (0.53% to 1.17%). Because the margin fell safely within the statistically verified interquartile range of independent regional commodity trading houses, the transaction met the arm's length principle.
3. Disqualification of the Internal Comparable Due to Material Bias: The resolution of this case resulted in the acceptance of all the Petitioner's arguments. The Board of Judges opined that the Respondent's correction, which imposed a 4.5 USCents premium, lacked a strong basis as it failed to consider significant differences in volume and contractual terms between the internal comparables used. Consequently, the export price reported by the Petitioner was declared to have met the Arm's Length Principle (ALP).

Implications: Formulating Airtight Economic Substance and Arm's Length Verification

The implication of this ruling reinforces the importance for Taxpayers to not only prepare formal Transfer Pricing Documentation (TP Doc) but also to be able to prove the substance of functions and risks of each entity in the supply chain. PT TSS's victory sets a precedent that the use of internal comparables by tax authorities can be refuted if there are material differences in transaction conditions that cannot be accurately adjusted.

• For multinational conglomerates, agricultural commodity exporters, and corporate tax directors, this landmark case guarantees that regional distribution centers and international sales offices can be legally insulated from aggressive, oversimplified internal database adjustments.
• Mandatory Controls Protocol for Affiliated Commodity Exports and Transfer Pricing Defense: To shield cross-border trading operations from arbitrary Internal CUP adjustments during DGT field audits, multinational tax defense groups must enforce a strict Functional, Asset, and Risk (FAR) Integrity and Commodity Documentation Protocol. Compliance units must structure corporate documentation to: (1) Maintain a contemporary Transfer Pricing Documentation (TP Doc) report that explicitly isolates internal spot-market transactions by applying quantitative volume-discrepancy adjustment models, (2) Embed precise chemical, physical, and quality specification charts (e.g., ash content, moisture, packaging standards) into commercial sales agreements to legally defend premium variations, and (3) Secure and archive end-to-end transaction records—including the offshore affiliate’s sales invoices, bills of lading, and distribution contracts with ultimate third-party users (such as Goodyear)—to deploy as an absolute look-through defense before the Tax Court.
