In the landscape of Indonesian international trade, the Mineral Export Price serves as the fundamental benchmark for determining the amount of Export Duty (Bea Keluar) that mining companies must pay to the state. For businesses operating in the extractive sector, understanding how these prices are set is not merely a matter of compliance, but a critical component of financial planning and logistics. The determination of these prices is strictly regulated to ensure that the state receives its fair share of revenue from the depletion of natural resources, while providing a transparent framework for exporters. This process involves a complex interplay between the Ministry of Finance and the Ministry of Trade, specifically through regulations such as PMK Number 80 of Year 2025 and various ministerial decrees that update price benchmarks periodically.

The calculation of export duties is not based on the transaction price found in a commercial invoice, but rather on a predetermined price known as the Harga Ekspor (Export Price). This mechanism prevents price manipulation and ensures uniformity across the industry. For mineral products, particularly high-value commodities like gold and copper concentrates, the pricing structure is highly technical, often depending on the chemical purity and the specific physical form of the mineral being shipped. As a senior customs practitioner, I have seen many businesses struggle with these nuances, particularly when transitioning between different regulatory updates or when dealing with complex mineral compositions.

Overview of Export Price Benchmarks for Mineral Products

The legal foundation for the imposition of export duties in Indonesia is rooted in Peraturan Pemerintah Nomor 55 Tahun 2008 concerning the Imposition of Export Duty on Export Goods. This government regulation mandates that the Minister of Finance has the authority to set export prices after receiving recommendations from the relevant technical ministers. For the mining sector, this involves close coordination with the Ministry of Trade and the Ministry of Energy and Mineral Resources.

Specifically, the Mineral Export Price is updated through ministerial decrees to reflect global market fluctuations. One of the most recent and relevant references is Keputusan Menteri Perdagangan Nomor 559 Tahun 2026, which specifically outlines the Harga Patokan Ekspor (HPE) and reference prices for mining products subject to export duties. This decree ensures that the prices used for customs calculations remain aligned with international commodity exchanges, such as the London Metal Exchange (LME) or the London Bullion Market Association (LBMA).

Exporters must be aware that the list of mineral products subject to these duties is quite specific. Under Peraturan Menteri Keuangan Nomor 38 Tahun 2024 (as amended by Peraturan Menteri Keuangan Nomor 68 Tahun 2025), the government identifies which minerals are restricted or taxed to encourage domestic downstream processing. By setting a high export duty or a high benchmark price, the government incentivizes companies to refine minerals locally rather than exporting raw ores.

Export Prices for Gold: Dore, Ingot, and Minted Bars

Gold remains one of the most strictly monitored commodities in the Indonesian customs regime. The Gold Export Duty is calculated based on a specific benchmark price that covers various forms of the precious metal. According to the current regulatory framework, the export price for gold is set at a significant value to reflect its status as a premium global asset. For instance, the reference price for various gold products is established at 157,267.62 USD/KGM (US Dollars per Kilogram).

This pricing applies to several specific tariff headings (HS Codes), including:

• 7108.12.10: Dore in the form of lumps, ingots, cast bars, and other primary forms.
• 7108.12.90: Gold or gold alloys in unworked forms, including granules and other non-dore shapes.
• 7115.90.10: Minted Bars, which are gold bars that have been processed and stamped by a refinery.

It is important for exporters to distinguish between Dore and Minted Bars. Dore is typically a semi-pure alloy of gold and silver produced at a mine site, which is then transported to a refinery. Minted bars, on the other hand, represent a more finished product. Despite these physical differences, the Mineral Export Price framework provides a unified benchmark for calculation, though the actual duty rate (percentage) may vary based on the level of processing as stipulated in the relevant Ministry of Finance regulations.

Special Provisions under PMK Number 80 of Year 2025

A pivotal regulation for the precious metals sector is PMK Number 80 of Year 2025. This regulation specifically governs the determination of export goods in the form of gold that are subject to export duty and the corresponding tariff rates. The introduction of this PMK serves to streamline the collection of state revenue from gold exports, which has historically been a complex area of customs valuation.

Under PMK Number 80 of Year 2025, the government emphasizes the importance of the technical characteristics of the gold being exported. For example, the regulation distinguishes between gold that is unworked and gold that has undergone specific refining processes. The Gold Export Duty is not just a flat tax; it is a strategic tool used to manage the flow of gold out of the country. Practitioners must ensure that the description of the goods in the Export Declaration (PEB) perfectly matches the categories defined in this PMK to avoid miscalculation and potential administrative penalties.

The Role of the Ministry of Trade

While the Ministry of Finance sets the duty rates, the Ministry of Trade provides the price data. As mentioned in Keputusan Menteri Perdagangan Nomor 559 Tahun 2026, the price reference for gold is based on the average international price over a certain period. This ensures that even if a company sells its gold at a discount to a subsidiary, the Mineral Export Price used for taxation remains at the fair market value defined by the state.

Calculating Copper Concentrate Prices based on Cu and Au Content

Unlike gold, which often has a flat benchmark per kilogram, the Copper Concentrate Price is determined through a more dynamic formula. Copper concentrate (classified under HS code ex 2603.00.00) is a product of the initial processing of copper ore. Because the quality of concentrate varies significantly from one mine to another, a single price would be unfair and inaccurate.

The export price for copper concentrate is determined based on a combination of its chemical components, primarily:

1. Copper (Cu) Content: The percentage of actual copper metal in the concentrate.
2. Gold (Au) Content: The amount of gold present as a secondary mineral within the copper concentrate.

As the levels of Cu and Au increase, the Mineral Export Price used for the Export Duty calculation also rises. This content-based pricing ensures that high-grade concentrates are taxed more than lower-grade materials. According to the regulatory data, the price for these concentrates can range from 2,048.85 USD/WE to as high as 10,672.24 USD/WE. This wide range highlights the necessity for accurate laboratory testing and assay reports before filing an export declaration. Customs officials will frequently verify these reports against the declared Copper Concentrate Price to ensure the state’s interests are protected.

Understanding Wet Metric Ton (USD/WE) Pricing for Minerals

In the mining industry, moisture content is a critical factor in logistics and pricing. For mineral concentrates, the Mineral Export Price is often expressed in USD/WE, which stands for US Dollars per Wet Metric Ton. This is a distinct measurement from the Dry Metric Ton (DMT) often used in commercial contracts.

The use of “Wet” weight in the customs context simplifies the weighing process at the port of loading. Since minerals like copper concentrate are often stored in open stockpiles or transported in bulk carriers where they can absorb or retain moisture, the gross weight includes this water content. The government sets the Mineral Export Price in USD/WE to provide a standard unit that can be easily verified by port scales and draft surveys.

Comparison of Pricing Units

Different minerals use different units of measurement in the export price list, which exporters must be careful not to confuse:

By understanding these units, exporters can accurately calculate their projected duty liabilities. For instance, a shipment of 5,000 Wet Metric Tons of copper concentrate would have its total Mineral Export Price calculated by multiplying the tonnage by the specific USD/WE rate determined by its Cu and Au content. This total value then becomes the base (Nilai Ekspor) to which the Export Duty percentage is applied.

Conclusion

Navigating the complexities of the Mineral Export Price system is essential for any mining operation in Indonesia. From the high-value benchmarks for the Gold Export Duty to the content-dependent Copper Concentrate Price, the regulations are designed to be precise and market-reflective. Compliance requires more than just knowing the current rates; it requires a deep understanding of the legal hierarchy, including PMK Number 80 of Year 2025 and the various decrees from the Ministry of Trade. By staying informed about these evergreen regulations and ensuring accurate mineral assays, businesses can ensure smooth customs clearance and maintain their standing as responsible corporate citizens in the global mining market.
