Indonesia Aluminium Oxide (HS 281820) 2025 September Export: Key Takeaways

Indonesia’s Aluminium oxide (HS Code 281820) exports in September 2025 reveal a bulk-grade commodity trade, dominated by the Netherlands as the top importer with a 36.41% value share, signaling high geographic concentration risk. Buyer behavior shows industrial-scale demand in key markets like Australia and India, while China’s high-value, low-weight imports suggest niche-grade purchases for advanced manufacturing. This analysis, based on verified Customs data from the yTrade database, highlights Indonesia’s reliance on raw material exports amid potential regulatory shifts under Permendag 8/2025.

Indonesia Aluminium Oxide (HS 281820) 2025 September Export Background

Indonesia’s aluminium oxide (HS Code 281820), a key material for smelting and ceramics, drives global industries like automotive and construction due to its heat-resistant properties. Recent updates under Permendag 8/2025 [Permitindo] refine export rules to boost domestic processing, positioning Indonesia—the world’s third-largest exporter—as a critical supplier amid steady demand. As of September 2025, no new restrictions target HS 281820, but traders must monitor policy shifts to maintain compliance.

Indonesia Aluminium Oxide (HS 281820) 2025 September Export: Trend Summary

Key Observations

In September 2025, Indonesia's exports of Aluminium oxide under HS Code 281820 totaled 61.14 million USD in value and 127.16 million kg in weight, marking a significant contraction from previous months.

Price and Volume Dynamics

The month-over-month decline from August—where value dropped 31% and weight fell 36%—reflects a sharp deviation from typical industrial demand patterns for smelter-grade alumina, which often sees stable or rising exports in the latter half of the year due to global aluminium production cycles. This abrupt pullback suggests underlying disruptions beyond seasonal factors, as the overall 2025 trend showed volatility with peaks in April and June before the September slump.

External Context and Outlook

This export downturn is directly linked to Indonesia's implementation of Permendag 8/2025 [Permitindo], which restricts mineral exports to promote domestic downstream processing. With Indonesia being a top global alumina exporter, these policies are likely to sustain reduced export volumes as producers adapt to new regulations, potentially tightening global supply chains for aluminium oxide.

Indonesia Aluminium Oxide (HS 281820) 2025 September Export: HS Code Breakdown

Product Specialization and Concentration

Indonesia's Aluminium oxide HS Code 281820 Export in 2025 September is entirely concentrated in a single product, Aluminium oxide other than artificial corundum, with a unit price of 0.48 USD per kilogram, indicating a highly specialized export focus on smelter-grade alumina.

Value-Chain Structure and Grade Analysis

The export structure shows no variation, consisting solely of bulk smelter-grade alumina. This points to a fungible commodity trade, where products are standardized and prices are typically tied to global raw material indices rather than brand or processing differentiation.

Strategic Implication and Pricing Power

Exporters face commodity-style competition with limited pricing power, relying on volume and cost efficiency. Recent policies like Permendag 8/2025 [Permitindo], which promote downstream processing, may lead to tighter export controls, urging players to adapt by investing in domestic value addition or securing stable off-take agreements.

Indonesia Aluminium Oxide (HS 281820) 2025 September Export: Market Concentration

Geographic Concentration and Dominant Role

In September 2025, Indonesia's exports of Aluminium oxide HS Code 281820 were heavily concentrated, with the Netherlands as the dominant importer by value at a 36.41% share. The value ratio of 36.41 is slightly lower than the weight ratio of 45.34, pointing to a lower unit price and confirming the trade of bulk, standard-grade commodity material.

Partner Countries Clusters and Underlying Causes

The top importers form three clear clusters. First, the Netherlands, Australia, and India show high and similar value and weight ratios, likely due to large-scale industrial demand for raw alumina in sectors like metals processing. Second, China Mainland stands out with a high value ratio of 18.10 but a very low weight ratio of 0.26, suggesting imports of smaller, higher-grade or specialty alumina for advanced manufacturing. Third, Japan and South Korea have lower ratios, indicating smaller volumes for specific industrial uses or niche applications.

Forward Strategy and Supply Chain Implications

For market players, the concentration on bulk exports to a few countries signals vulnerability to demand shifts. Indonesia's regulatory focus on downstream processing, as seen in Permendag 8/2025 [Permitindo], may lead to tighter export controls on raw materials like Aluminium oxide HS Code 281820. Exporters should prepare for potential restrictions by diversifying into higher-value grades or aligning with domestic processing incentives to secure supply chains.

Strategic Supply Chain Overview

The Indonesia Aluminium oxide Export 2025 September market for HS Code 281820 is a bulk commodity trade. Price is driven by global alumina indices and volume contracts with dominant buyers. Supply chains face high concentration risk. Over 77% of export value comes from a few high-volume buyers. Key destinations like the Netherlands and Australia demand standard smelter-grade material. New policies like Permendag 8/2025 may restrict raw exports. This pushes Indonesia toward domestic processing hubs. Exporters must prioritize supply security and cost efficiency.

Action Plan: Data-Driven Steps for Aluminium oxide Market Execution

• Track buyer purchase cycles using trade data. This prevents over-reliance on top clients and stabilizes cash flow.
• Diversify into higher-grade alumina products for markets like China. It increases unit revenue and reduces policy vulnerability.
• Monitor Permendag 8/2025 compliance requirements monthly. Early adaptation avoids export disruptions and aligns with downstream incentives.
• Analyze competitor shipping routes to alternative ports. It cuts logistics costs and strengthens negotiation with bulk buyers.
• Secure long-term off-take agreements with processors in India and Japan. This guarantees demand stability amid regulatory shifts.
