Professional Liability Insurance


The Professional Liability Insurance Plan for ACS members protects you against claims alleging errors, omissions and/or negligence arising from your professional services.

Whether you are employed full-time, consulting independently or a business owner, protection is available to you at a competitive price with the exclusive ACS Professional Liability Insurance Program.

The ACS Professional Liability Insurance Program was created specifically for ACS members and features the broad breath of coverage required of Chemical Consultants.

The plan, administered by Hays Affinity and underwritten by Lloyd’s of London, features:

  • Competitive Group Pricing
  • Limits starting at $250,000 per claim, up to $1,000,000 per claim
  • Part-Time Coverage Option
  • Dedicated Claims Attorney
  • Risk Management Resources
  • Premium Financing Available

To find out more about the features, costs, eligibility, renewability, limitations and exclusions visit the Hays Affinity website.

Coverage is being offered through the Chemical Society Risk Purchasing Group (CSRPG), a risk purchasing group that was established for members of American Chemical Society (ACS) and its program the American Association of Chemistry Teachers (AACT).  Therefore by completing an application and purchasing the insurance, an ACS or AACT member becomes a member of CSRPG.
