By route
Our quality policy is designed around one practical question: what happens when something goes wrong. We define responsibility, timing, and recovery actions in advance.
Incoming-material checks based on approved specification sheets
In-line inspections at key production checkpoints
AQL 1.0 / 1.5 / 2.5 plans depending on risk category
Photo evidence and bilingual inspection report before release
Traceability by lot number, production date, and operator line
Critical / Major / Minor classification is documented per project. Release requires predefined acceptance outcome.
For confirmed nonconforming lots, we execute rework or replacement plans with accountable owners and deadlines.
Compensation terms are specified in the master agreement to avoid ambiguity under delay or quality incidents.
