1. Legal Framework for Coal Supply Arbitration

A. Domestic Law

Law No. 30 of 1999 on Arbitration and Alternative Dispute Resolution

Governs domestic and international arbitration in Indonesia.

Recognizes binding arbitration agreements and enforcement of awards in civil courts (Articles 1–4, 9, 65–69).

Provides that arbitration can cover commercial disputes, including commodity supply contracts.

Mineral and Coal Mining Law (Law No. 3 of 2020 / Mining Law)

Regulates coal mining, sale, and export.

Requires parties to comply with permits (IUP/IUPK) and local content rules.

Disputes regarding contracts, royalties, or export obligations are often resolved via arbitration, especially for international buyers.

B. International Arbitration

Coal supply contracts often involve foreign buyers/exporters, so parties include arbitration clauses under ICC, SIAC, LCIA, or UNCITRAL rules.

Indonesia is a New York Convention (NYC) signatory, ensuring recognition and enforcement of foreign-seated awards.

C. Common Parties

Coal producers: PT Bukit Asam, PT Adaro, PT Kideco.

International buyers: power plants, commodity traders (Singapore, China, India).

Logistics and shipping contractors.

2. Common Dispute Types

Price adjustment disputes – changes in coal price due to market fluctuations or formula disputes.

Volume disputes – failure to deliver contracted quantities.

Quality disputes – calorific value, ash content, sulfur levels.

Export obligations – non-compliance with licensing or export quotas.

Force majeure claims – natural disasters, port blockages, or regulatory changes.

Payment and performance disputes – delayed payments or letter-of-credit issues.

Arbitration is preferred due to cross-border transactions, technical specifications, and time-sensitive export contracts.
