Here’s the buyer-first summary. If your brand name is on the label, you usually act as the responsible person and must ensure the listing is submitted and kept current.

Our MOQ starts at 5,000 units per SKU, with sampling taking 10-14 days including 3 torque validation cycles.
We perform ASTM D3078 vacuum testing and provide leak test reports.
Production lead time is 45-60 days after approval.
We’ve reduced leakage rates by 92% for clients using our triple-seal system with pressure-sensitive liners and foil induction seals.
