How to sell empty genuine HP45 shells internationally
If you accumulate empty genuine HP45 (51645A) cartridges, you can sell them into MufengTech’s international buyback flow instead of discarding sound shells. The process is quote first, pack carefully, ship to the Hong Kong remanufacturing intake, then accept the graded inspection result before payment. Only genuine original empties are accepted. Compatible, remanufactured, and previously refilled cartridges are outside the buyback scope.
Shenzhen Mufeng Technology, established in 2012, operates this recycling route under MufengTech. This article explains how overseas offices, print shops, factories, and collectors prepare an international shipment. It links to the existing grades guide and packing pages. It does not publish fixed buyback prices, and it does not use HP-authorised or HP-logo marketing language for MufengTech products.
Confirm the empties are genuine original shells before you quote
Buyback accepts genuine original HP45 / 51645A empty shells that meet intake rules. Sort out everything else before you message for a quote. Non-original, compatible, remanufactured, or previously refilled cartridges are not accepted. Cracked or drilled shells and damaged nozzle plates or contacts are also rejected.
If a shell has holes, plugs, glue marks, or other refill evidence, do not include it in the sellable count. Mixed loads slow inspection and can reduce the payable quantity. When unsure, send clear photos on WhatsApp before shipping.
MufengTech’s finished goods side is separate from buyback. The company sells Новый and Восстановленный black cartridges with an MOQ of 10 units each. Those product pages describe independent compatible supply. They are not HP-branded or HP-official products, and empty compatible or remanufactured shells from the field are still not accepted for buyback.
Use grades A, B and C as your pre-shipment estimate
Final grade is set at inspection in Hong Kong. Your pre-shipment estimate only helps the indicative quote. The existing guide HP45 empty cartridge grades explained and the price list and grades page use the same A / B / C framework.
| Grade | What it usually means | What to check before packing |
|---|---|---|
| A | Отлично | Clean shell, intact original label, undamaged nozzle plate and gold contacts, no drill holes or plugs, bagged or sealed after use |
| B | Хорошо | Light scratches or scuffs, dried ink that cleans off, label slightly worn; nozzle plate and contacts still undamaged |
| C | Удовлетворительно | Heavier wear, damaged or missing label, heavy dried ink or older stock; shell still genuine, uncracked, with a testable nozzle plate |
| Not accepted | No payment for these items | Compatible / remanufactured / previously refilled shells; cracked or drilled bodies; damaged nozzle plate or contacts |
Recycling prices are not fixed. They depend on grade, quantity, and current demand. The final price is confirmed via WhatsApp after inspection. Do not publish or promise a unit price from this article.
Follow the international quote-to-payment sequence
- Sort genuine original HP45 / 51645A empties only.
- Estimate A / B / C quantities using the grades guide.
- Send quantity, estimated grade mix, country, and photos on WhatsApp to +86 158 1405 1051.
- Receive an indicative grade-based quote. Keep the quote reference for the carton label.
- Pack and ship to the Hong Kong receiving address provided after the quantity is confirmed.
- Wait for inspection counts by grade and any rejection reasons.
- Confirm the final WhatsApp price, then receive payment on the agreed terms.
Bulk pickup is available for 1,000 units or more. Shipping cost is agreed by mutual negotiation. Risk of loss in transit stays with the sender until delivery, so packing quality protects both grade and shipment value.
Pack for export grade protection, not just carton survival
Follow the site’s how to pack and ship instructions:
- Bag each cartridge in its own sealed plastic bag; use the original clip or tape if available.
- Protect the nozzle plate; do not wipe it with paper or leave shells loose where nozzles can rub.
- Pack tightly in a strong double-wall carton and fill gaps with bubble wrap or paper.
- Label the carton with the quote reference and include a packing list with name, quantity, and contact.
- Send the tracking number on WhatsApp after dispatch.
Do not ship loose ink, toner, other cartridge models, or waste. Items not accepted, or sent in error, receive no payment and cannot be returned; they are routed for responsible material recycling according to the published intake rules.
Keep buyback language separate from New / Remanufactured sales
International sellers often ask whether returned empties become the remanufactured stock they can buy later. Operationally, accepted genuine shells are inspected, cleaned, refilled, and quality-tested at the Hong Kong base, then offered through the remanufactured product path. Commercially, keep the conversations separate:
- Buyback: genuine original empties only; graded A / B / C; no fixed public price.
- Sales: New or Remanufactured finished cartridges; MOQ 10; price on request.
- Claims: no HP trademark licence, authorisation, or official-product wording for MufengTech supply.
Send a complete sell-empties request
