The seller must submit a 50-gram sample of the dried ground kratom leaf powder from the same lot as the products ready for delivery. It should be sent to the Company to inspect the volume of active ingredients (% Mitragynine) and ensure it meets the specific criteria before the actual shipment.
The Company will notify the seller whether the testing results of the active ingredient volume meet the purchasing criteria.
The Company will issue a Purchase Order (PO) specifying the quantity in kilograms and the buying price (calculated based on the active ingredient volume) to the seller, alongside a 50% deposit payment of the total product value stated in the PO.
The seller must ship the products to the Company matching the quantity specified in the PO within 7 days after receiving the purchase order.
Upon receiving the shipment, the Company will re-test the active ingredient levels and specific characteristics of the delivered products. If the active ingredient volume is found to be lower than the initial sample submitted, the purchasing price will be recalculated based on the actual active ingredient volume.
If the product contains a very low volume of active ingredients (less than 1.0%), the Company reserves the right to reject that entire lot. The seller will be notified to collect the returned goods from the Company, and the seller must refund the 50% deposit back to the Company within 7 days after being informed of the test results.
The Company will process the remaining 50% payment within 7 days after the products have been received and successfully verified for active ingredient levels and structural specifications.
