How We Remanufacture HP45 Cartridges in Hong Kong

Our remanufacturing base is in Hong Kong, where our team has years of experience remanufacturing cartridges. Every remanufactured cartridge we sell has passed inspection, cleaning, refilling and quality control there.

The closed loop

We only buy genuine HP original empties because the remanufacturing process depends on a sound original shell and print head. Each cartridge that passes QC goes back into service — and can come back to us when it is empty again.

We Only Buy Genuine HP Original HP45 Cartridges

We accept genuine HP original HP45 (51645A) cartridges only. Non-original, compatible, remanufactured or previously refilled cartridges are not accepted.
