Procurement Process

Purchasing and Active Ingredient Testing Procedures

  1. Step 1

    Sample Submission

    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.

  2. Step 2

    Result Notification

    The Company will notify the seller whether the testing results of the active ingredient volume meet the purchasing criteria.

  3. Step 3

    Purchase Order Issued

    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.

  4. Step 4

    Product Delivery

    The seller must ship the products to the Company matching the quantity specified in the PO within 7 days after receiving the purchase order.

  5. Step 5

    Re-testing & Quality Control

    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.
