Specification

Packaging

We provide tailored packaging to fit different logistics needs. The standard option is 25kg plastic woven bags, each lined with a PE inner layer—this dual structure blocks moisture, dust, and contamination during transit and storage. For large-volume orders, 1000kg bulk bags are available, which support efficient bulk handling and cut down on packaging waste and shipping costs. Custom packaging is also offered: we can adjust sizes, add brand printing, or use specialized materials based on your requirements, ensuring the packaging matches your operational and branding needs.

Delivery:

Our delivery process balances speed and reliability. Standard orders have a 10-15 day lead time, starting from payment and order confirmation; urgent orders can be prioritized with adjusted timelines by mutual agreement. All shipments depart from Qingdao Port, a key global hub with wide-ranging ocean freight connections, enabling cost-effective and timely delivery. We support FOB, CFR, and CIF terms: for FOB, we handle loading at Qingdao Port; for CFR and CIF, we arrange full shipping (including freight, and insurance for CIF) to your destination port, partnering with trusted carriers to ensure safe arrival. 

Storage Guidelines:

Proper storage preserves the product's quality. Keep it in a cool, dry, well-ventilated area with temperatures between 5°C and 25°C, and relative humidity below 60%. Place packages on pallets or shelves (not directly on the ground) to avoid moisture absorption. Keep it away from rain, water sources, strong acids, or alkalis—these can trigger chemical changes that reduce effectiveness. Handle packages gently to avoid damage; once opened, seal bags tightly after each use to prevent moisture entry and caking. Following these steps maintains the product's solubility and nutrient content throughout its shelf life.
