limonene price

Limonene quality is primarily determined by its purity levels (typically 93% to 96% for technical grade, and >98% for food/fragrance grade). Buyers must request a Certificate of Analysis (COA) to verify the refractive index (1.471–1.474) and specific gravity (0.841–0.846). For high-end applications, ensure the product is cold-pressed or steam-distilled to maintain chemical stability and scent profile.

As a chemical substance, Limonene must comply with REACH regulations for the EU market and TSCA (Toxic Substances Control Act) for the US. If used in food or cosmetics, ensure the supplier provides Food Grade certification (FCC) and follows GMP (Good Manufacturing Practices). Additionally, because it is flammable, a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) is mandatory for international transport.

Limonene is a byproduct of the citrus industry; therefore, global orange crop yields significantly impact market price. D-Limonene (extracted from citrus peels) is generally more cost-effective than L-Limonene. Buyers should monitor harvest seasons in major producing regions like Brazil and Florida to time their bulk purchases when supply is at its peak to secure lower unit costs.

When used as a degreaser or solvent, the Kauri-Butanol (KB) value is essential to measure cleaning strength. Ensure the moisture content is <0.05% to prevent corrosion in metal cleaning applications. For 3D printing (HIPS filament dissolution), high terpene content is required for efficient performance without damaging the primary model.

Limonene is classified as a Class 3 Flammable Liquid (UN 2319). It requires specialized hazardous materials (HazMat) packaging and labeling. Ensure your freight forwarder is experienced in handling IMO/IMDG-compliant shipments. Using fluorinated HDPE drums or stainless steel tanks is critical to prevent the chemical from reacting with or leaching through the container.

Limonene is highly susceptible to oxidation, which degrades its quality and changes its color. To prevent this, request that suppliers use nitrogen blanketing (nitrogen flushing) during the drumming process. Always specify the use of opaque, airtight containers and, if possible, include antioxidants like BHT if the end-use application allows, to extend shelf life during sea freight.

When sourcing via Made-in-China.com, look for Audited Suppliers with verified chemical production licenses. Negotiate based on tiered pricing (e.g., 1-5 tons vs. 20ft FCL). Request a pre-shipment inspection (PSI) by third parties like SGS to verify that the batch matches the approved sample, and use Secure Payment terms to protect your capital until the shipping documents are verified.

Check the HS Code (typically 2902.19) for specific import duties in your country. Be aware of anti-dumping duties that may apply to chemical exports from certain regions. Always calculate the Total Landed Cost, including anti-dumping taxes, customs clearance fees, and the Hazardous Material Surcharge levied by shipping lines, to ensure economic feasibility.
