Lubricants | Base Oil, Additive & Specialty Chemical Supporting
7DCHEM provides lubricant chemical supply and supporting services for Ukraine and Central and Eastern Europe. The company maintains long-term and stable cooperation with major Chinese refineries including Panjin Huajin, Liaohe Petrochemical, Fushun Petrochemical and Dalian Hengli Refinery. Supported by dual warehouses in Poland and China-Europe land and sea transportation routes, we supply a full range of base oils, lubricant additives, finished industrial lubricants and fuel additives.

The climate of Ukraine and Central and Eastern Europe is characterized by low temperatures, high humidity and severe outdoor salt spray in winter, which commonly causes equipment starting failure, oil emulsification, metal corrosion and sludge accumulation. Complicated cross-border procedures and unstable delivery cycles, together with generic lubricant formulas incompatible with local equipment and working conditions, further lead to increased equipment failures and production downtime losses. To solve the above problems, we provide customized formulation, oil testing, compliance document processing and stable delivery services to reduce equipment failure rates and shutdown losses.
Local Condition Adapted Technical Services

Custom Formulas for Low-temperature and High-humidity Conditions in Eastern Europe
In view of the local long winter and outdoor salt spray corrosion conditions, we deploy dedicated additive systems to improve the low-temperature fluidity, demulsibility, rust resistance and oxidation resistance of lubricants. This optimizes equipment operation during seasonal transitions and ensures stable performance of lubrication systems.
One-on-one Formula Adjustment by Equipment Working Condition
Equipment such as gearboxes, hydraulic units, generators, air compressors and transformers operates under different parameters and working conditions. We adjust additive proportions according to actual on-site conditions and provide mature and ready-to-use formulas to reduce customers' formula debugging costs.


In-service Oil Testing and Hidden Risk Inspection
We support on-site oil sampling and laboratory testing and analysis to identify potential risks such as oil oxidation, medium contamination and mechanical wear. Corresponding optimization and rectification solutions are provided to avoid unplanned equipment shutdowns.
Stable Raw Material Supply System

High-Quality Raw Material Supply
Relying on the supply chain of multiple large domestic refineries for a long time, we stably supply high-end base oils such as low-pour-point, naphthenic and hydrofinished base oils with sufficient inventory and stable batch supply capacity, realizing highly consistent oil quality between batches and ensuring end-product performance from the source.
Transparent Delivery with Local Polish Warehousing
Supported by dual warehouse bases in Poland, we flexibly undertake various order demands including bulk shipments, small orders and full container loads. For customized lubricants, special synthetic oils and special-specification products, we clarify the delivery plan and cycle in writing before contract signing, strictly perform obligations in accordance with contract agreements, and realize traceable and controllable delivery progress throughout the whole process.

Core Product System
Base Oils
Base oils determine the viscosity, temperature resistance and service life of lubricants. We supply a full range of API Group I–V base stocks including mineral oils, hydrotreated oils, PAO, PAG and synthetic esters, which meet the blending requirements of industrial, automotive and low-temperature special equipment lubricants.
Lubricant Additives
Our product portfolio covers full-category single additives and compound packages including detergent, dispersant, antioxidant, extreme-pressure anti-wear, pour point depressant, rust inhibitor and defoamer. Customers can adopt mature formulas or conduct independent component blending. We maintain long-term stable supply partnerships with Ruifeng New Materials and Handi Fluid.
Finished Industrial Lubricants
We keep stock of turbine oil, hydraulic oil, gear oil, compressor oil, mineral and synthetic transformer oil. All products comply with European equipment standards and can be provided with complete test reports and compliance documents.
Fuel Additives
Applicable to gasoline, diesel and biofuels, our fuel additives include anti-gelling, carbon cleaning, anti-corrosion and bactericidal agents, which optimize fuel combustion performance and extend fuel storage life.
Logistics and Delivery
The delivery cycle of all orders is confirmed in contracts with full logistics traceability. Conventional base oils, general additives and standard small-pack lubricants are in stock in Polish warehouses. Custom compound additives, specialty synthetic base oils and low-temperature tailored formulas are produced on demand. Non-standard products, large-batch orders, special-certification products and customized repackaging products are managed as special projects and delivered in strict accordance with contractual agreements.
Safety and Compliance Assurance
Lubricant and fuel chemicals are hazardous chemical materials. Adhering to the core principle of safety and compliance, we provide safety document sorting, pre-compliance inspection, hazardous goods packaging formalities, cross-border risk assessment and on-site operation guidance to ensure the safety of personnel, equipment and plant operation.

Seven-dimensional Pre-control Guarantee System
The system covers five core guarantees including EU REACH/CLP compliance declaration, full-life-cycle seven-dimensional pre-control management, standardized procurement procedures, unified service standards, and localized delivery for Central & Eastern Europe and Ukraine, fully avoiding cross-border trade compliance risks and ensuring efficient project implementation and stable performance.
Low-carbon & Sustainable Development Services
We provide low-VOC environmentally friendly additive alternative solutions, assist enterprises in carbon footprint accounting and compliance document sorting. Our products meet the low-carbon procurement requirements of the EU CBAM.


Partners are not required to stock inventory. Tiered rebates are provided based on annual purchase volume.
