Kava extract

The primary active compounds in Kava are Kavalactones. When sourcing for B2B purposes, you must specify the Kavalactone content, which typically ranges from 30% to 70% for concentrated extracts. Ensure the supplier provides a Certificate of Analysis (COA) that identifies the chemotype profile (the numerical sequence of the six major kavalactones), as this determines the specific effects (e.g., relaxation vs. sedation) and ensures the product is derived from Noble Kava varieties rather than non-noble 'Tudei' varieties.

The two most common methods are CO2 Extraction and Ethanol/Water Extraction. CO2 extraction is considered the gold standard as it is a solvent-free process that preserves the integrity of the kavalactones without leaving chemical residues. If using solvent-based extraction, ensure the supplier complies with USP <467> Residual Solvents limits to guarantee consumer safety.

Since Kava is a dietary supplement/food ingredient, suppliers must adhere to GMP (Good Manufacturing Practices). Essential documentation includes ISO 22000 or HACCP for food safety management. For entry into markets like the US, the facility should be FDA registered, and the product must meet heavy metal limits (Lead, Arsenic, Cadmium, Mercury) and microbiological standards (E. coli, Salmonella, Mold/Yeast) as verified by third-party lab testing.

Kavalactones are sensitive to light, heat, and oxygen. The extract should be stored in vacuum-sealed, light-proof aluminum foil bags or high-density polyethylene (HDPE) drums. It is critical to maintain a cool, dry environment (below 25°C). For bulk cross-border shipping, ensure the outer packaging is robust enough to prevent moisture ingress, which can lead to clumping or degradation of the powder.

Kava regulations vary significantly by country. For example, it is legal in the USA (under DSHEA) but has strict restrictions or bans in parts of the EU and UK. Before placing an order, consult with a local customs broker to confirm the HS Code (typically 1302.19) and specific labeling requirements. Always source from reputable platforms like Made-in-China.com where you can verify the supplier's business license and export history.

Do not negotiate on price alone, as low-cost Kava often indicates the use of stems or peelings instead of the lateral root, which reduces quality. Request a pre-shipment sample from the same batch as the bulk order. Use Tiered Pricing strategies: aim for a 10-15% discount on volumes exceeding 500kg, and insist on Trade Assurance or secure payment terms to protect your capital until the quality is verified by an independent lab.

Always conduct factory audits or hire a third-party inspection service (like SGS or Intertek) to perform a Loading Supervision. Ensure the sales contract explicitly states that the Kavalactone percentage must match the COA, and include a refund clause if the product fails third-party purity tests upon arrival. Conduct all communications and payments through professional channels to maintain a verifiable paper trail.
