What usually delays eye care production lead time: packaging, testing, or labeling?

Quick Answer (for busy buyers)

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.

• From an OEM/ODM execution standpoint, packaging is usually the #1 driver of eye care lead time delays, more than labeling.
• Once formula and samples are confirmed, bulk production itself is typically 10-20 working days, but packaging purchasing can take 10-30 working days and often becomes the critical path.
• Common packaging timing examples: outer single unit carton about 15 days, set box about 20 days; inner packaging like glass bottles about 15 days, acrylic bottles up to 30 days, soft tubes about 15 days.
• If you change bottle type, pump, or artwork late, it usually resets supplier scheduling.
• Testing and documentation can also add time, but it is more predictable when started early.
• Typical internal checks include packaging testing around 3 days, raw material production 5-7 days, raw material testing 5 days, and finished goods manufacturing about 7 days.
• We can support product testing submission and tracking, plus documentation support (e.g., certificates and barcode), but we cannot guarantee regulatory outcomes.
• MOQ guidance: most items start at 1000-3000 pcs depending on packaging and complexity.
