Citronella oil

Buyers must distinguish between Java type (Cymbopogon winterianus) and Ceylon type (Cymbopogon nardus). The Java type is generally preferred in B2B sourcing due to its higher Geraniol (35-45%) and Citronellal (30-45%) content, which determines its efficacy in insect repellents and fragrances. Ensure the Refractive Index (1.466-1.473) and Specific Gravity (0.880-0.895) align with international standards to confirm purity.

As a chemical substance, Citronella Oil must be accompanied by a Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch. For entry into the EU, REACH registration is essential. If the oil is intended for aromatherapy or cosmetics, look for ISO 22716 (GMP) or USDA Organic certifications. For biocide applications (repellents), compliance with the EPA (USA) or BPR (EU) regulations is critical.

Citronella oil is frequently adulterated with cheaper synthetic terpenes or kerosene. To mitigate this risk, require GC-MS (Gas Chromatography-Mass Spectrometry) test reports from the supplier. This analysis provides a 'fingerprint' of the oil, ensuring no synthetic additives or heavy metals are present. Requesting a pre-shipment sample for independent lab testing is a standard best practice for high-volume contracts.

Citronella oil is sensitive to light and oxidation. It should be stored in epoxy-lined steel drums or dark amber glass containers to prevent reaction with the metal or UV degradation. Ensure the supplier uses nitrogen blanketing during the bottling process to displace oxygen, which extends the shelf life to typically 24 months when stored in a cool, dry place.

Citronella Oil has a flashpoint typically between 50°C and 60°C, classifying it as a Class 3 Flammable Liquid (UN1266 or UN1169) for international shipping. You must ensure the supplier provides UN-approved packaging and correct IMO/DGR labeling. Failure to declare it as dangerous goods can lead to heavy fines, shipment seizure, or carrier blacklisting.

Prices for essential oils fluctuate based on crop yields. Secure a fixed-price contract for a specific duration to hedge against market volatility. For MOQs, while many suppliers set a 25kg or 180kg drum minimum, you can negotiate a trial order of 1-5kg for quality validation. Always use Trade Resources or Secured Payment services on Made-in-China.com to protect your funds until the COA is verified.

Verify the HS Code (typically 3301.29) with your local customs broker to determine import duties. Ensure the Commercial Invoice and Packing List exactly match the descriptions on the MSDS. Some countries require a Phytosanitary Certificate because the product is derived from plant matter; confirm if your local customs authority mandates this before the vessel departs.

Prioritize Audited Suppliers on Made-in-China.com who have undergone third-party onsite inspections by agencies like SGS or Bureau Veritas. Check their export history and specifically ask for their distillation capacity to ensure they are a primary producer rather than a middleman, which ensures better traceability and price stability.
