Groups frequently engage related manufacturers under contract or toll manufacturing arrangements and compensate them through a routine mark-up or conversion fee. However, the contractual label alone does not determine the appropriate return. The actual allocation of ownership, functions, assets and risks must form the basis of the transfer pricing analysis.

Understanding the Manufacturing Models

In a typical toll manufacturing arrangement, the principal supplies the raw materials, retains ownership during production and pays the manufacturer for processing. Under a contract manufacturing arrangement, the manufacturer may procure inputs, fund working capital and sell finished goods to the principal.

These are broad commercial distinctions rather than rigid classifications. Actual ownership, procurement responsibilities, funding arrangements and control over inventory risks must be examined before determining the manufacturer’s profile.

Determining the Appropriate Cost Base

A toll manufacturer that does not own the raw materials would generally be remunerated for its manufacturing functions, with the cost base reflecting the activities and expenses it actually undertakes.

Including materials merely handled by the manufacturer in a marked-up cost base may distort its return. Conversely, a contract manufacturer that procures and funds inputs may require a different analysis. The selected profit level indicator should reflect the functions performed, costs incurred and risks assumed.

Capacity Utilisation and Idle Costs

Manufacturing arrangements should also address under-utilised capacity. Independent parties may negotiate minimum volume commitments, take-or-pay clauses or compensation for dedicated capacity.

Where a group manufacturer bears idle capacity costs, the analysis should establish which entity controlled the relevant capacity decisions and whether the contractual allocation reflects actual conduct. Comparing production volumes with installed capacity can help identify whether the claimed risk allocation is commercially supportable.

Manufacturing Intangibles and Process Contributions

Local manufacturing teams may develop process improvements, improve yields, design tooling or contribute valuable technical know-how. Such contributions should not automatically be treated as routine manufacturing activities.

The development, enhancement, maintenance, protection and control of relevant know-how should be examined to determine whether additional remuneration is warranted.

Cross-Border Tax and Regulatory Considerations

The principal’s personnel, activities and authority at the manufacturing location may require a separate permanent establishment assessment under the applicable domestic law and tax treaty. Quality inspections or production supervision do not, by themselves, automatically create a permanent establishment.

Customs and indirect tax treatment must also be considered in light of the actual movement and ownership of goods and the nature of the processing arrangement.

Conclusion

Contract and toll manufacturing arrangements require remuneration that reflects the functions performed and risks actually controlled. Groups should document ownership of materials, procurement responsibilities, capacity utilisation, process contributions and the basis of remuneration, and ensure that contractual terms remain consistent with operational conduct.
