Garlic oil

The quality of garlic oil is primarily determined by its Allicin content and the extraction method used. Steam distillation is the standard for high-purity essential oils, while CO2 extraction preserves more heat-sensitive compounds. Buyers should request a Certificate of Analysis (COA) to verify the density (0.910–1.100 g/cm³) and refractive index. Ensure the product is 100% pure and natural, free from carrier oils like soybean oil unless specifically requested for softgel formulations.

Depending on the end-use (food, health supplement, or pesticide), different regulations apply. For food grade, ensure the supplier is ISO 22000 or HACCP certified. If intended for the US market, FDA registration is mandatory. For European markets, compliance with REACH regulations and EFSA standards is required. Always verify the MSDS (Material Safety Data Sheet) to ensure safe handling and transport compliance.

Garlic oil is versatile: in the food industry, it is used for flavoring and preservation due to its antimicrobial properties; in pharmaceuticals, it is processed into softgel capsules for cardiovascular health; and in agriculture, it serves as a natural biopesticide. Buyers must specify the grade—Food Grade, Pharma Grade, or Technical Grade—to match these specific functional needs.

Garlic oil is sensitive to light, heat, and oxygen. High-quality suppliers should provide packaging in amber glass bottles, fluorinated HDPE drums, or epoxy-lined aluminum canisters. The shelf life should be at least 24 months when stored in a cool, dry place. Ask the supplier about their antioxidant stabilization methods if the oil is intended for long-term storage.

Garlic oil has an extremely pungent and persistent odor, which can lead to 'cross-contamination' of other cargo. It is often classified as Class 9 Miscellaneous Dangerous Goods or restricted by certain airlines. Ensure the supplier uses triple-layer sealing technology and consult with freight forwarders on Made-in-China.com who specialize in chemical and essential oil logistics to avoid shipment rejection.

To ensure transaction security, use Secure Payment services provided by reputable platforms like Made-in-China.com. Never wire full payments to private accounts. Conduct third-party factory audits (such as SGS or Intertek) to verify the supplier's production capacity and on-site storage conditions before releasing large deposits.

Garlic oil prices fluctuate based on the raw garlic market harvest cycles. To secure the best rates, consider annual volume contracts rather than spot buying. Negotiate based on active ingredient concentration (Allicin %); a higher price for a more concentrated oil may offer better economic feasibility when factoring in reduced shipping costs per active unit.

Check the HS Code (typically 3301.29) for your specific country to determine import duties. Be aware of anti-dumping duties that some regions apply to garlic-derived products from specific origins. Ensure all Export Customs Declaration documents accurately reflect the product grade to avoid delays in customs clearance.
