Indonesia’s new rare-earth testing requirements have disrupted shipments of nickel products, delaying mandatory surveyor reports and customs clearance for cargoes of nickel pig iron (NPI), high-grade NPI and mixed hydroxide precipitate (MHP), according to industry representatives and government officials.
At least 120 bulk commodity vessels were reportedly unable to sail as the checks were introduced, Indonesian Nickel Industry Forum (FINI) chairman Arif Perdanakusumah said. The disruption affected export hubs across the archipelago, including nickel-producing Sulawesi, the Bangka Belitung Islands and West Kalimantan.
The immediate bottleneck was administrative rather than a formal ban on nickel exports. Exporters could not complete clearance without a Laporan Surveyor, or LS survey report, while surveyors and authorities worked to determine how newly detected rare-earth content should affect shipments whose primary products were nickel, alumina, bauxite or copper.
The government’s coordination meetings on July 30 and 31 subsequently clarified that exports should be assessed according to the primary product classification. That interpretation allowed officials to begin releasing delayed cargoes while the Trade Ministry reviews the relevant rules and develops clearer limits for associated rare-earth content.
Testing requirements halted the normal clearance process
The testing programme was introduced after authorities increased scrutiny of mineral exports following a rare-earth-related enforcement case in Pangkalpinang, on the island of Bangka. The case raised concerns about whether rare-earth material had been incorrectly reported or exported without the required controls.
In response, surveyors began checking mineral cargoes for rare-earth elements and radioactive materials, including uranium and thorium. The expanded testing was applied to a range of processed products, including NPI, ferronickel, nickel matte, MHP, alumina and copper cathodes.
For exporters, the critical issue was the LS report. The document is required for customs processing, meaning a cargo without an issued report could not complete export formalities even if its principal product already met existing specifications.
FINI said the system was not ready to handle the expanded requirements. Industry concerns included the absence of quantitative thresholds, limited laboratory capacity, a lack of testing equipment at some locations and uncertainty over which agencies were responsible for final verification.
“ No LS means no export clearance ” became the practical result for affected shipments, as cargoes remained at ports or vessels waited for documentation to be completed.

According to Mining Weekly’s report, about 120 surveyor reports were still awaiting issuance late in July. The reports covered multiple commodities and mining regions, not only nickel.
ANTARA separately reported that FINI had cited at least 120 ships unable to depart as of July 20. The figures describe related but not necessarily identical measures of the disruption: pending surveyor reports on one hand and affected vessels on the other.
The Pangkalpinang case widened scrutiny across mineral exports
Pangkalpinang became the focal point for the regulatory response because rare-earth elements can occur as associated or by-product materials in mineral streams, particularly in regions with tin and other heavy-mineral production.
The enforcement action prompted authorities to examine whether rare-earth elements were present in other exported mineral products. That broader approach brought nickel cargoes into the inspection process, even though NPI and MHP are not primarily rare-earth products.
FINI said it supported testing to improve Indonesia’s knowledge of its rare-earth resources. However, the association argued that the presence of rare-earth elements as by-products should not automatically prevent otherwise compliant nickel products from being exported.
The distinction is important for the nickel supply chain. Indonesia is a major producer and processor of nickel, with exports ranging from NPI and ferronickel used largely in stainless steel to MHP used in the battery-materials chain. A broad interpretation of the rules could therefore affect both traditional nickel consumers and battery manufacturers.
What changed in the export process
| Issue | Effect on shipments | Government clarification |
|---|---|---|
| Additional rare-earth and radioactive-element testing | Longer laboratory and surveyor processing times | Testing and verification to continue |
| Delayed LS survey reports | Customs clearance and vessel departures blocked | Previously delayed reports could be issued under clarified guidance |
| Rare-earth content found in nickel products | Uncertainty over whether cargoes were restricted | Primary product classification should govern treatment |
| Naturally occurring radioactive material | Potential additional compliance review | Export may proceed if safety and monitoring requirements are met |
| Unclear content thresholds | Case-by-case interpretation | Trade rules are being reviewed and revised |
The government’s response sought to separate the export of rare-earth elements as a primary product from the incidental presence of rare-earth content in other commodities.
July coordination restored a route for nickel shipments
The Presidential Staff Office, customs authorities, the Attorney General’s Office, the Trade Ministry and other agencies held discussions to resolve the backlog.
The July 30 coordination meeting and the follow-up letter issued on July 31 established that export requirements should be applied to the primary mining product and its derivatives. Under that interpretation, an NPI, high-grade NPI or MHP shipment should be assessed according to its nickel classification, applicable HS code and product specifications rather than automatically being treated as a prohibited rare-earth export because testing detected associated elements.
The government also clarified that naturally occurring radioactive material could be cleared if it passed the relevant tests and complied with safety and monitoring requirements.
On July 31, state surveyor PT Sucofindo was authorized to issue 85 previously delayed reports, most of them linked to exports of alumina, copper cathodes and nickel derivatives, according to KSP Chief Dudung Abdurrachman. ANTARA reported that mineral exports resumed while the Trade Ministry regulation was being revised.
That did not remove all compliance uncertainty. The government still needs to define the maximum permissible rare-earth content in non-rare-earth mineral exports, establish consistent testing procedures and clarify which laboratories and surveyors can perform the work.

Market impact extends beyond the vessels at anchor
The first market effect is logistical. Delayed vessels can create demurrage costs, interrupt delivery schedules and force buyers to source replacement units from other suppliers. For smelters and traders operating on tight working-capital cycles, even a short delay can affect inventory planning and payment timing.
The second effect is uncertainty over the reliability of Indonesian supply. The country already plays an outsized role in the global nickel market, and its export flows are closely watched by stainless steel producers, battery-material manufacturers and commodity traders.
The disruption does not necessarily imply a lasting reduction in Indonesian nickel availability. The government has said that shipments containing associated rare-earth elements can proceed when the main product is compliant. But the episode shows how quickly a new control applied across mineral exports can affect products that are not the target of the original restriction.
This is particularly relevant for NPI and MHP. NPI is an important feedstock for stainless steel, while MHP is a key intermediate for producing nickel sulphate and other battery chemicals. A delay in either stream can affect regional premiums even if global annual production remains unchanged.
The episode also adds to existing uncertainty around Indonesia’s nickel policy. As discussed in Skillings’ nickel market outlook, tighter mine approvals and the country’s large downstream processing base have created a growing sensitivity to disruptions in ore and product flows.

What exporters and buyers will monitor next
The immediate question is whether the remaining backlog of LS reports can be cleared without creating separate practices between ports, industrial parks or surveyors.
Operators will also be watching for four developments:
- Formal rare-earth thresholds for nickel and other mineral products.
- A standardized laboratory method for rare-earth, uranium and thorium testing.
- A definitive list of accredited testing bodies and surveyors.
- Consistent customs treatment based on primary product classification.
Until those details are codified, exporters may continue to face delays even after the government’s clarification. Cargoes containing trace or associated elements could still require additional documentation, while surveyors and customs officials may apply transitional guidance cautiously.
For nickel buyers, the practical lesson is that supply risk can arise from documentation and testing capacity as much as from mine output or smelter production. The July disruption affected cargoes that were already processed and ready for export. The constraint was the clearance process.
Indonesia’s decision to let mineral exports resume has reduced the immediate risk of a prolonged stoppage. However, the next phase of the policy review will determine whether the episode remains a short-lived administrative disruption or becomes a recurring compliance issue for the country’s nickel export chain.
