What to include in your inquiry
- Your organization name and the contact handling procurement.
- Product names, requested specifications or pack sizes, and quantities.
- Delivery country and postal code, plus any preferred shipping service.
- Requested delivery timeframe and whether the requirement is a one-off or recurring inquiry.
- Required COA, analytical documentation, batch matching or origin information.
- Any purchase-order, invoice or internal procurement requirements that need review.
If you need a quantity, specification or service that is not listed, describe it in the inquiry. Availability, minimum order requirements, pricing and any custom requirements must be confirmed for that request; an inquiry does not confirm supply capability.
How a business order proceeds
- Submit your requirements. Use Contact Us with the product, quantity, destination and documentation information.
- Review the proposed order. We check availability and what information can be supplied, then confirm the specification, quantity, total price, delivery estimate and applicable terms.
- Confirm documents and payment details. Resolve essential procurement conditions before payment. Use only the payment method available for the order at checkout or confirmed in the written quotation.
- Prepare and dispatch. Order preparation begins after full payment, complete order details and required documentation checks. Tracking is provided when available after dispatch is confirmed.
Pricing and payment
Quotations remain valid for 72 hours from issue unless a different expiry is stated. A quotation alone does not reserve stock; availability should be reconfirmed before payment. Prices and any applicable shipping or other charges are confirmed for the order.
Default terms are 100% payment in advance. Partial payments or credit terms require a separate written agreement. Available currencies, recipient details and any relevant payment network are confirmed for that order. Customers pay sending fees charged by their bank or blockchain network; any additional applicable charges are disclosed before payment.
Availability, dispatch and shipping
In-stock orders normally dispatch within 1–2 business days after full payment, complete order details and any required documentation have been confirmed. Lead times for other orders, large quantities or custom requirements are reviewed before payment.
We ship to destinations available at checkout or confirmed in a written quotation. Estimated transit after carrier acceptance is 6–8 business days by express service or 10–15 business days by standard service. These estimates exclude order processing, customs delays and holidays and are not guaranteed arrival dates.
Standard shipping is free for eligible orders with a merchandise subtotal of USD 500 or more after discounts, excluding taxes and shipping charges. Destination eligibility and any separate charges for express upgrades, remote destinations, oversized consignments or special handling are confirmed before payment. For other currencies, the quotation states the applicable threshold.
Customers pay applicable import duties, taxes and customs fees unless these are expressly included in the written quotation.
Documentation for procurement review
Batch-specific COA or analytical documentation may be available for selected products. Availability, test scope, issuing party and applicable batch vary by product. We do not represent that all products undergo the same tests or that every batch has the same documents.
If the available report cannot be matched to the proposed delivery batch, we explain that limitation. Confirm essential document requirements before ordering. If you need manufacturing-origin, packaging-location or dispatch-location information, include the requirement so it can be checked for the specific product and order.
Distribution inquiries and order support
Prospective distribution partners may submit their business details and intended requirements for review. Sending an inquiry or purchasing products does not grant authorized distributor status; that requires a separate written authorization.
For order changes, ordinary returns or shipment issues, contact support with your order number. Ordinary return requests must be submitted within 14 calendar days after delivery and are subject to unopened-item and other policy conditions. Incorrect, damaged, missing or verified non-conforming goods are reviewed separately. See Customer Help for the applicable procedure.
Wholesale inquiry questions
Does an inquiry reserve stock or confirm supply?
No. An inquiry does not confirm supply capability, and a quotation alone does not reserve stock. Reconfirm availability and resolve essential procurement conditions before payment.
Does purchasing grant authorized distributor status?
No. Sending an inquiry or purchasing products does not grant authorized distributor status. That requires a separate written authorization.
