Payment Options
Card checkout for everyday orders, and fee-free bank wire (T/T) for equipment purchases, purchase orders and distributor volumes. Whichever route you take, your order ships from our US warehouse in 3–5 business days.
Paying by Bank Wire? Start Here →Which payment method should I use?
Most makers buying a single desktop extractor should just check out with a card. Wire transfer exists for the orders where cards get awkward — multi-unit builds, school and university purchase orders, and distributor container loads.
| Method | Best for | Order confirmed | Ships |
|---|---|---|---|
| Credit / debit card Visa · Mastercard · Amex · JCB · UnionPay |
Single units, filters, adapter kits — anything under $1,000 | Instantly at checkout | Same or next business day |
| Bank wire / T/T USD telegraphic transfer |
Orders over $1,000, multi-unit builds, PO-based purchasing, distributors | When funds clear (1–3 days domestic, 2–5 international) | On payment confirmation |
| Purchase order (PO) Schools, universities, makerspaces |
Institutions that must issue a PO before paying | On approved PO, paid by wire afterwards | Per agreed terms |
| Industrial systems Quote-based |
Central systems, 3-phase units, custom ducting | On signed quotation and deposit | Per production lead time |
Paying by Bank Wire (T/T)
Choose Bank Transfer (T/T) at checkout — no card details required. We email a formal PDF commercial invoice with our full beneficiary bank details within one business hour, and your units stay reserved while you arrange the transfer.
Place the order
Add your units to the cart and select Bank Transfer (T/T) at checkout. Your order is created with a Pending status and your stock is held.
Receive your invoice
Within one business hour (Mon–Sat, 9:00–18:00 GMT+8) we email a PDF commercial invoice with our bank details, SWIFT code and your order number as the reference.
Send the transfer
Instruct your bank to send the invoice total in USD, quoting your order number. Email us the wire confirmation (MT103) so we can start processing immediately.
We ship
On payment confirmation we mark the order paid and dispatch from the US warehouse. Tracking arrives by email the same day.
Before you send a wire
Four things that prevent almost every delay we see on international transfers.
Select “sender pays all charges” (OUR). Intermediary banks deduct fees en route. If charges are shared, the amount arriving is short of the invoice total and we cannot release the order until the balance is settled.
Transfer in USD only. Payments in other currencies may be rejected or returned by our bank, which costs both sides another 3–5 days.
Quote your order number in the reference field. This is how we match your payment within minutes instead of hours.
Email us the MT103 or transfer receipt. In many cases this lets us begin picking and packing before funds fully settle.
We never change our bank details by email after your invoice is issued. If you receive any message asking you to wire funds to a different account — even if it appears to come from us — do not pay it. Contact us directly at info@zxhbco.com or by WhatsApp to verify first.
Why we prefer wire on large orders
Card networks charge a percentage of every transaction. On a multi-unit equipment order that is real money — money we would rather put into your freight or your spare filter set than hand to a processor. Wire transfer carries no processing fee for either of us, which is why it is our recommended route above $1,000.
Need a formal quotation or PO first?
Schools, universities, makerspaces and companies with procurement processes usually need a quotation on letterhead before a PO can be raised. Tell us the models and quantities and we will issue one the same business day.
