I am looking for suppliers who can provide a bulk purchase of organic jojoba oil. The desired quantity is over 500 litres, and I require a certification of organic quality along with details of sourcing practices. The oil should have a low free fatty acid content and be suitable for cosmetic applications. I am particularly interested in suppliers based in New Zealand or Australia to minimize shipping times and costs. Please ensure that your pricing is competitive, and include any minimum order quantities in your response.
