Premium performance blends designed for maximum engine longevity and protection under demanding operating circumstances.
South Korea remains a dominant global powerhouse in heavy manufacturing, automotive production, shipbuilding, and maritime transport. As the world's major shipbuilding nation and home to massive port facilities such as Busan and Incheon, Korea handles an immense volume of container traffic and heavy cargo logistics daily. The lubrication needs of these operations are highly demanding.
Furthermore, South Korea has adopted highly stringent environmental regulations. The government enforces rigorous emission standards (comparable to Euro VI and Stage V requirements) for both on-highway commercial vehicles and off-road industrial machinery. Under these regulatory environments, heavy-duty fleets and industrial operators must implement advanced lubricating technologies to ensure equipment compliance, prevent exhaust after-treatment system fouling, and lower total ownership costs.
Korean logistics and heavy construction entities are rapidly moving toward Low SAPS (Sulfated Ash, Phosphorus, and Sulfur) lubricating oils. Standard oils can rapidly poison catalysts and clog Diesel Particulate Filters (DPFs). By utilizing high-end Group III hydrocracked base stocks paired with modern additive formulations, modern operators can prolong device lifespans while achieving exceptional engine durability.
Our production protocols focus on meeting API CK-4, CJ-4, and CI-4 Plus specifications, ensuring that our Korean import partners secure lubricants that directly match the engine warranties of prominent manufacturers such as Hyundai, Volvo, Scania, and Doosan.
For over 15 years, Shandong Longhai has innovated, formulated, and exported top-tier lubricant products worldwide.
Established in 2009 and headquartered in the industrial hub of Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech enterprise integrating advanced R&D, processing, and global logistics. Covering a production base of 131 acres, we support an annual output capacity exceeding 200,000 tons of high-grade lubricants.
Our strategic proximity to Shandong's major shipping ports (such as Qingdao) creates a highly efficient supply chain line directly to Incheon, Busan, and Gwangyang. This geographic advantage allows us to offer Korean procurement offices reliable shipping pipelines, short delivery windows, and optimized container freight rates.
We operate fully automated manufacturing plants equipped with advanced gravimetric blending vessels and automated dosing facilities. Our filling lines achieve a consistent accuracy range between 1‰ and 2‰ while operating 20% to 35% faster than legacy setups. This speed ensures that high-volume orders for Korean distribution networks are packaged, quality-cleared, and containerized on schedule.
Quality and safety are core priorities at Longhai. Our facilities operate under strict compliance with global standards, backed by international product liability coverage from the People's Insurance Company of China (PICC).
From custom viscosity tuning to localized packaging compliance, we handle the entire process seamlessly.
Our dedicated laboratory engineers formulate fully synthetic, semi-synthetic, and premium mineral engine oils customized to the climatic challenges, driving patterns, and machinery architectures of South Korea. We align our custom mixtures with performance metrics dictated by API, ACEA, JASO, and key automotive manufacturers.
How we ensure quality, compliance, and timely supply delivery for Korean importing partners.
Evaluating application requirements, specifications, and volume demands.
Developing customized oil blends tailored to Korean environmental conditions.
Providing physical samples for laboratory validation and approval.
Executing automated production with precise gravimetric accuracy controls.
Monitoring fleet performance, lubricant life cycles, and shipment updates.
Our manufacturing plants utilize digital control and precision laboratory equipment to ensure high product quality and reliability.
Providing options for diesel and gasoline powertrains, heavy machinery hydraulics, and industrial gears.
Expanding lubricant distribution in South Korea requires careful alignment with local regulations. These include K-REACH (Korea Registration, Evaluation, Authorization and Restriction of Chemicals) compliance, MSDS updates registered with the Ministry of Employment and Labor (MOEL), and proper disposal parameters under the Waste Management Act.
Our technical team ensures all product formulations meet these guidelines, providing clear documentation, K-REACH verification, and detailed safety datasheets with every shipment. We also design packaging labels with clear Korean text instructions to simplify customs processing and commercial handling.
Our products are engineered to maintain viscosity stability in low-temperature operations down to -35°C, ensuring rapid oil pressure build-up and reduced engine wear during Korean winter operations in northern districts.
Essential for protecting Diesel Particulate Filters (DPFs) and Selective Catalytic Reduction (SCR) systems used in modern machinery.
Helps prevent oil breakdown and maintain oil film strength under high running temperatures in heavy transport and construction environments.
Provides acid neutralization to extend lubricant drain intervals, helping fleet operators reduce maintenance costs.
Answers to key technical and logistical questions from Korean importing agents and fleet purchasing offices.
