Regulators, distributors and consumers all want the same thing: to know exactly which unit is in front of them and where it came from. For a CKD assembly operation, adding serial number marking and unit traceability is the step that moves you from an assembler to a certified, trustworthy manufacturer.
When every assembled stove carries a unique serial number, you can track a unit from its kit batch, through each assembly stage, to its final test record. If a defect or recall ever occurs, you can identify the exact batch and units affected — protecting your customers and limiting your liability. It is also a requirement for many local certification and export schemes.
A serial number is only useful if it ties to a record. Pair each marked unit with a simple paper or spreadsheet log — kit batch, assembly date, operator, leak-test result, and final QC pass. Even a lightweight system gives you full traceability without heavy IT investment.
THREEMI supplies gas stove CKD kits and advises on the full assembly setup — including serial marking equipment, rating-plate sourcing, and how to build a practical traceability process. We help you set up a line that produces not just stoves, but certified, trackable products.
