Do European buyers require PAO or expiry date for hair care, and how is it determined?

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.

• In the EU, hair care products must comply with Regulation (EC) No 1223/2009, which mandates an expiry date for products with a shelf life under 30 months or a Period After Opening (PAO) symbol for longer shelf life.
• This is determined via stability testing, where we simulate real-world conditions to assess product integrity over time.
• As your OEM partner, we conduct accelerated testing (e.g., 3-month cycles at elevated temperatures) to estimate shelf life and PAO, followed by real-time monitoring for validation.
• For MOQ, we recommend at least 5,000 units per SKU to justify testing costs and ensure batch consistency.
• Sampling for stability tests typically takes 3-4 weeks, using pilot batches to mirror final production.
• Packaging must be compatible to avoid interactions affecting PAO; we check material seals and viscosity changes under humidity.
• Documentation includes stability reports, ingredient safety dossiers, and labeling proofs for EU submission.
• Lead time from testing to production is 8-12 weeks, factoring in microbial hold-times and compliance audits.
• We assist with all necessary tests and docs but cannot guarantee regulatory approval, as final decisions rest with authorities.
