Engineered for high-temperature stability, extreme pressure protection, and extended drain intervals in heavy-duty manufacturing and transmission systems.
As Vietnam cements its position as a global manufacturing powerhouse, the country's heavy industries—ranging from steel mills in Vũng Tàu and cement production in Thanh Hóa, to electronics manufacturing in Bắc Ninh and massive marine shipping fleets in Hải Phòng and Ho Chi Minh City—are operating at record capacities. These continuous operations demand high-efficiency mechanical systems where gearboxes, reduction drives, and hydraulic networks act as the critical core.
However, running mechanical equipment in Vietnam presents unique engineering challenges. The tropical monsoon climate, characterized by ambient temperatures frequently exceeding 38°C and relative humidity levels hovering above 85%, accelerates lubricant degradation. Standard mineral gear oils often experience viscosity shear, rapid oxidation, and severe water emulsification, leading to premature gear tooth wear, pitting, micro-pitting, and costly unscheduled factory downtime.
Why Longhai formulations excel under Vietnam's challenging tropical environment and heavy mechanical loads.
To resist the twin threats of heat and moisture, Longhai's gear oils utilize premium Group II and Group III base stocks, combined with a highly specialized sulfur-phosphorus extreme pressure additive package. This formula delivers several key technological advantages:
Shandong Longhai Lubrication Technology Development Co., Ltd., established in 2009 and headquartered in the industrial hub of Zibo, Shandong, is a premier high-tech enterprise integrating scientific R&D, advanced production, and international sales. Over the last 15 years, we have built a fully integrated supply chain system dedicated to delivering world-class lubrication solutions globally.
Longhai operates its flagship brand "Century Longhai" alongside international strategic brand partnerships, including the British "A Ba" series. Our comprehensive product portfolio spans heavy-duty diesel engine oils, passenger car motor oils, industrial gear oils, hydraulic transmission fluids, turbine oils, air compressor oils, refrigeration lubricants, and automotive cooling fluids. To guarantee complete peace of mind, all our products carry comprehensive liability insurance through the People's Insurance Company of China (PICC).
Our commitment to quality is backed by rigorous international standard certifications. Longhai is certified under:
These credentials guarantee that every batch dispatched to Vietnam meets precise API, ACEA, and AGMA specifications, ensuring maximum protection for imported European, American, Japanese, and Chinese machinery.
Capitalizing on geographical proximity, the ASEAN-China Free Trade Area, and rapid maritime shipping corridors.
For procurement officers in Vietnam, managing total cost of ownership (TCO) and lead times is paramount. Importing gear oil from Longhai’s refinery in Shandong offers massive structural advantages:
Develop proprietary brands or custom viscosity profiles matched exactly to your mechanical specifications and market conditions.

Expert answers to common engineering, procurement, and import questions for Vietnamese industrial operators.
High humidity accelerates moisture condensation inside enclosed gearboxes, leading to oil emulsification, loss of film strength, and rust. For Vietnamese operations, it is critical to use L-CKD gear oils with premium demulsibility additives that quickly separate water from the oil, allowing water to settle at the bottom of the casing for easy draining without degrading the lubricating matrix.
L-CKD gear oils offer superior anti-oxidation performance, improved extreme pressure anti-wear capabilities, and greater thermal stability compared to L-CKC grades. This transition is essential for heavy-duty reducers operating under high continuous loads or high temperatures, as it prevents micro-pitting fatigue and extends drain intervals by 50% to 100%.
Yes. Under the ASEAN-China Free Trade Agreement (ACFTA), importers can secure preferential customs tariffs (often reduced to 0%) by presenting a valid Certificate of Origin (Form E). Longhai complies with all export regulations and provides complete Form E documents to facilitate smooth import clearances in Haiphong, Da Nang, and Ho Chi Minh City ports.
All raw base oils and additives undergo rigorous chemical profiling before blending. Our automated Zibo production plant utilizes smart metering to ensure blending accuracy within 1‰-2‰. Each batch is analyzed in our ISO-compliant laboratory, and retain samples are kept for a minimum of 2 years to ensure complete traceability.
Yes. Our joint innovation R&D center specializes in modifying viscosity indices and additive dosages to match specific equipment tolerances, load parameters, and localized operating temperatures. We provide custom-formulated ISO VG 100, 150, 220, 320, 460, and 680 grades to optimize performance in mature machinery.
