Exporting Mixed Hydroxide Precipitate to the US — Battery Supply Chain Procurement

Mixed Hydroxide Precipitate (MHP) is a critical intermediate product in the lithium-ion battery supply chain, serving as a key feedstock for the production of nickel and cobalt sulfates used in cathode active materials. As the United States accelerates domestic battery manufacturing under the Inflation Reduction Act and related policies, securing reliable and ethically sourced MHP has become a strategic priority for procurement teams at cathode producers, battery cell manufacturers, and automotive OEMs. This page provides a comprehensive overview for US buyers seeking to source MHP from Latin America and other global suppliers, covering specifications, supplier landscapes, procurement practices, import requirements, pricing context, and how Coppermont facilitates these transactions.

The Role of MHP in US Battery Supply Chains

Mixed Hydroxide Precipitate is produced by hydrometallurgical processing of nickel laterite ores, typically through high-pressure acid leaching (HPAL) or atmospheric leaching. The resulting slurry is filtered and dried into a greenish-brown powder containing mixed nickel and cobalt hydroxides, along with other metal impurities. MHP is then shipped to refineries where it is leached and purified to produce nickel sulfate (NiSO₄) and cobalt sulfate (CoSO₄)—the essential precursors for NMC (nickel-manganese-cobalt) and NCA (nickel-cobalt-aluminum) cathode chemistries. With US demand for lithium-ion batteries projected to grow from 300 GWh in 2023 to over 1,000 GWh by 2030, the need for MHP imports is expected to rise sharply, particularly as domestic mining capacity remains limited [1].

Product Specifications and Grades Relevant to US Buyers

MHP is traded based on its nickel and cobalt content, typically ranging from 35% to 55% nickel and 1% to 10% cobalt, depending on the ore source and processing method. US buyers prioritize specifications that align with downstream refining capabilities and final product quality. Key parameters include:

Nickel Content: Most US refineries prefer MHP with nickel content above 40%, ideally between 45% and 50%, to ensure economic viability of downstream processing. Lower-grade MHP may require additional concentration steps, increasing costs and lead times.

Cobalt Content: Cobalt levels vary significantly by source; typical ranges are 2% to 8%. Buyers with specific cathode chemistry requirements (e.g., NMC 811 or NMC 622) may seek MHP with cobalt content consistent with their production targets.

Impurity Limits: Strict limits are placed on impurities such as magnesium (Mg), manganese (Mn), aluminum (Al), and iron (Fe), which can interfere with solvent extraction and purification. Typical maximums are Mg < 1.5%, Mn < 0.5%, Al < 0.3%, and Fe < 0.2%.

Moisture Content: MHP is typically shipped with moisture content between 20% and 40%. Buyers specify maximum moisture levels to avoid excessive shipping costs and degradation during transport.

Physical Form: MHP is supplied as a filter cake or dried powder, with particle size distribution often specified to ensure proper handling and dissolution in refinery circuits.

US buyers typically reference ASTM standards for metal content analysis and may request certification from accredited laboratories. The industry standard for nickel and cobalt determination is ASTM E1479-99 (reapproved 2019) for inductively coupled plasma (ICP) analysis [2].

LATAM and Africa Supplier Landscape for MHP

Latin America has emerged as a significant supplier of MHP to the US, driven by large nickel laterite deposits in countries such as Brazil, Colombia, and the Dominican Republic. Brazil is the largest producer in the region, with Vale’s operations in Pará state and the recent ramp-up of the Santa Rita mine by Atlantic Nickel. In 2023, Brazil exported approximately 120,000 metric tons of MHP, with over 60% destined for the US [3]. Colombian producers, including Cerro Matoso (South32), supply high-cobalt MHP suitable for specialty battery applications. The Dominican Republic’s Falcondo mine has historically produced ferronickel but is pivoting to MHP production to meet battery demand.

Africa is also a growing source, particularly from Madagascar’s Ambatovy project and the Democratic Republic of Congo (DRC), where MHP is produced as a byproduct of cobalt mining. However, supply chain risks in the DRC—including political instability and artisanal mining concerns—lead many US buyers to prefer Latin American sources due to shorter shipping routes and more stable regulatory environments.

Other notable suppliers include Indonesia, which has rapidly expanded HPAL capacity, though most output is consumed by Chinese and Korean refineries. The Philippines and New Caledonia also produce MHP but face logistical challenges for US buyers.

US Buyer Types: Who Buys MHP and How They Procure

The primary US buyers of MHP are:

Cathode Active Material (CAM) Producers: Companies like BASF, Umicore, and LGChem operate refineries in the US and Europe that convert MHP into battery-grade sulfates. These buyers typically require long-term offtake agreements (3–5 years) with fixed pricing formulas tied to LME nickel and cobalt prices, plus a processing fee. They prioritize supply security and consistent quality.

Battery Cell Manufacturers: Tesla, Panasonic, and SK Innovation source MHP indirectly through CAM suppliers or directly for integrated operations. They demand rigorous environmental, social, and governance (ESG) compliance, including adherence to the OECD Due Diligence Guidance for Responsible Supply Chains.

Trading Houses and Aggregators: Firms like Glencore, Trafigura, and Mercuria act as intermediaries, purchasing MHP from multiple producers and consolidating shipments to meet refinery specifications. They offer flexibility in pricing and delivery terms but may add margin.

Government and Strategic Stockpiles: The US Department of Defense and Department of Energy have shown interest in building strategic reserves of battery materials, including MHP, to reduce reliance on adversarial nations. Procurement is conducted through competitive tenders with strict security and sourcing requirements.

Procurement processes vary: large buyers issue requests for proposals (RFPs) with detailed technical questionnaires, while smaller buyers may negotiate spot contracts. All buyers require samples for metallurgical testing before committing to volume shipments.

Certifications and Import Requirements for MHP

Importing MHP into the US requires compliance with several regulatory frameworks:

Customs and Tariffs: MHP is classified under HS code 2825.90.9000 (other inorganic bases, metal hydroxides). The current tariff rate is zero under the WTO Most Favored Nation (MFN) schedule, but buyers should monitor potential changes under Section 232 or Section 301 trade actions [4].

Environmental and Safety Regulations: MHP is not classified as hazardous under US DOT regulations, but shipping documentation must include Safety Data Sheets (SDS) per OSHA Hazard Communication Standard (29 CFR 1910.1200). The material may be subject to TSCA reporting if it contains certain impurities.

ESG and Due Diligence: US buyers increasingly require certification under the Responsible Minerals Initiative (RMI) or the Initiative for Responsible Mining Assurance (IRMA). The OECD Due Diligence Guidance for conflict-affected areas is mandatory for companies sourcing from the DRC or adjoining countries [5].

Quality Certifications: Suppliers should provide certificates of analysis (CoA) from ISO 17025 accredited laboratories. Many buyers require ISO 9001 quality management certification for production facilities.

Shipping and Logistics: MHP is typically shipped in bulk containers or big bags, with moisture content declared. The US Coast Guard requires compliance with the International Maritime Dangerous Goods (IMDG) code if the material exhibits corrosive properties.

Pricing and Lead Time Context

MHP pricing is primarily driven by LME nickel and cobalt prices, with a discount for processing costs and impurities. As of early 2025, nickel prices have ranged from $16,000 to $22,000 per metric ton, while cobalt has traded between $25,000 and $35,000 per metric ton. MHP typically trades at 70% to 85% of the contained metal value, depending on grade and impurity levels. For a typical shipment with 45% nickel and 5% cobalt, the value per wet metric ton would be approximately $7,000 to $10,000 [6].

Lead times from Latin America to US Gulf Coast ports range from 10 to 20 days for sea freight, plus 5 to 10 days for inland transport to refineries. Air freight is rarely used due to cost. Buyers should allow 4 to 6 weeks from contract signing to delivery, including sampling and testing. Bulk shipments are typically 5,000 to 20,000 metric tons per vessel.
