Customer Complaint Submission Form

How to Contact Us
Our Customer Complaint submission form is available for reporting and submitting complaints about West's stoppers, seals, vials, or plastic components. Complaints can be submitted in several formats.

  • Please note you will need to submit a new complaint form for every separate item. Multiple defects for one item can be entered with one submission form.
  • Supporting documents can include inspection sheets, laboratory reports, process details, photographs and video to assist the investigation.
  • Submitting defective samples in support of product quality complaints is required for a thorough investigation.
  • If you request return and credit for product in question, all inspection details including a reference number of your specification and detailed defect levels need to be provided. Only after a thorough investigation and West Pharmaceutical Services written agreement will any approvals be granted.
