Cetane improver

The primary active ingredient in most high-quality cetane improvers is 2-Ethylhexyl Nitrate (2-EHN). When sourcing, you must verify the purity level (typically ≥99%), as impurities can lead to engine deposits. Additionally, check the moisture content (should be <0.05%) and acidity levels to prevent corrosion in fuel systems. For cold-weather applications, ensure the pour point is compatible with your target climate.

A professional supplier should provide a dosage-response curve. Generally, a treat rate of 500 to 2000 ppm (parts per million) should yield a 3 to 8 point increase in Cetane Number (CN). You should request ASTM D613 (CFR engine test) or ASTM D7668 (IQT test) reports to validate the actual ignition delay improvement. High-efficiency additives reduce ignition delay, improve cold start performance, and lower combustion noise.

Since Cetane Improvers are hazardous chemicals, they must have a valid Material Safety Data Sheet (MSDS/SDS) compliant with GHS standards. For international trade, ensure the product has a REACH registration (for EU markets) or is compliant with EPA fuel additive regulations (for the US). The packaging must meet UN-certified standards for Class 3 or Class 6.1 hazardous materials depending on the specific formulation.

Cetane improvers are essential for oil refineries to upgrade low-quality diesel streams, fuel blenders creating premium diesel grades, and large-scale fleet operators (mining, shipping, and logistics) looking to improve fuel economy and reduce emissions (NOx and particulate matter). They are also widely used in biodiesel blending to bring the cetane rating up to petroleum diesel standards.

Cetane Improver (2-EHN) is a combustible and thermally unstable liquid. It is classified as Dangerous Goods (DG) for transport. You must ensure the supplier uses ISO Tanks or UN-approved steel drums. It is critical to avoid high-temperature exposure during transit; therefore, stowage away from heat sources on vessels is mandatory. Always confirm the supplier's experience with DG Declaration to avoid customs seizures.

For high-value chemical orders, utilize Trade Assurance services on Made-in-China.com to protect your payment. To ensure quality consistency, mandate a Pre-shipment Inspection (PSI) by a third party like SGS or Intertek. They should perform random sampling from the actual batch being shipped to verify the Nitrogen content and purity against the provided Certificate of Analysis (COA).

Prices for 2-EHN are heavily influenced by raw material costs (octanol and nitric acid). Negotiate based on volume-based pricing tiers; purchasing in Full Container Loads (FCL) or ISO Tanks can reduce unit costs by 15-25% compared to LCL. Request a formula-based pricing agreement for long-term contracts to hedge against market volatility.

Verify the HS Code (typically 3811.19) and associated import duties in your country. Some regions require an Import License for hazardous chemicals. Ensure all labels are in the local language and include the necessary hazard pictograms. Failure to align with International Maritime Dangerous Goods (IMDG) codes can result in heavy fines at the port of entry.
