  • Housing Scam Alert

    The American Chemical Society does not endorse third party companies who contact our delegates and exhibitors to book accommodations through their companies for the ACS Spring 2020 National Meeting & Exposition. These third party “pirate” companies reach out to delegates and exhibitors offering special discounted hotel rooms for other associations’ meetings. Often, these discounted rooms do not exist. The primary objective of this solicitation is to obtain credit card information. ConferenceDirect, the ACS Housing Services Provider, will not contact you by phone or email requesting credit card information for reservations. ACS has no affiliation with these companies and is unable to guarantee rates and accommodations made through these companies.

    Please note that ConferenceDirect is the ONLY Housing Services Provider for the ACS Spring 2020 National Meeting & Exposition in Philadelphia, PA. ACS does not endorse booking hotel reservations through any other sources. Please do not be misled by companies that solicit you over the phone and misrepresent themselves as the ACS Housing Services Provider. If you are contacted by one of these third party companies, please contact ConferenceDirect immediately.

    All correspondence received from ConferenceDirect regarding housing for the ACS Spring 2020 National Meeting & Exposition will include the housing services provider official logo seal.

    For accurate information regarding reservations or availability, please contact our housing services provider ConferenceDirect at acshousing@conferencedirect.com or the call center at (844) 293-7040 US Toll Free or (704) 837-4855 International.

  • Registration Policy

    Registration credentials/badges must be worn for all technical sessions and poster presentations. Admittance to National Meeting special events in the Convention Center and official meeting hotels will require badges to be worn at all times.

    All attendees including presenters must register and pay the appropriate registration fee to present and attend the meeting. Invited speakers should contact their symposium organizer or division program chair to clarify terms of their invitation. Presenters who fail to register for the meeting will have their abstract withdrawn from the official meeting program, technical programming archive, and CAS database.

    U.S. attendees who register by January 8, 2020 will receive their registration credentials and tickets via mail prior to the meeting. Unless an international attendee has provided a U.S. mailing address on their registration form, their credentials must be picked-up onsite at the Attendee Registration (this includes Canada and Mexico). After January 8, 2020, registrations will continue to be accepted at the standard rate on-line and by phone or fax (credit card payment only) until March 26, 2020.

  • Cancellation/Refund Policy

    By adhering to the following cancellation procedure, cancellations received by February 12, 2020 will receive a refund, less a $50 administrative fee. Registrants must return a copy of the registration confirmation along with the original registration credentials before refund will be issued. All refunds are issued via the same method used for payment. No cancellation/re-fund requests will be honored after February 12, 2020.

  • Attendee List Scam

    The American Chemical Society does not sell email lists of members or meeting registrants. Distribution or other use of the list without ACS’ express authorization is strictly prohibited. Third party “pirate” companies reach out to delegates and exhibitors offering to sell these lists often with the primary objective of obtaining credit card information. ACS is aware that these solicitations occur but has no affiliation with these companies. Please contact the National Meetings team with any questions or concerns.

  • Recording & Photo Release Policies

    The use of any device to capture images (e.g., cameras and camera phones) or sound (e.g., tape and digital recorders) or stream, upload or rebroadcast speakers or presentations is strictly prohibited at all official ACS meetings and events without the express written consent from the ACS.

    In registering for this public event, attendees grant to the American Chemical Society, its affiliates and licensees (collectively referred to as “the Society”), royalty-free permission, including the exclusive worldwide, irrevocable rights in all languages, to reproduce in all formats, including, but not limited to print, microfilm, electronic, and/or CD-ROM, likeness as shown in the photograph(s) or recordings taken by official meeting photographers at the American Chemical Society National Meeting & Exposition.

    Attendees waive the right to inspect or approve any copy that is used in connection with the photographs and release and discharge the Society from any and all claims arising out of use by the Society of the photographs for the purposes described above, including any claims for libel and invasion of privacy.

  • Volunteer/National Meeting Attendee Conduct Policy

    One of the key strengths of the ACS has been the enduring and varied contributions made by its thousands of dedicated volunteers.

    Another unassailable strength of the ACS is its outstanding national meetings program. ACS national meetings are among the most respected scientific meetings in the world. ACS national meetings offer scientific professionals a legitimate platform to present, publish, discuss, and exhibit the most exciting research discoveries and technologies in chemistry and its related disciplines. Furthermore, ACS national meetings facilitate networking opportunities, career development and placement, and provide organizations with opportunities to exhibit products and services to targeted audiences.

    The Society’s Congressional Charter explicitly lists among its objectives “the improvement of the qualifications and usefulness of chemists through high standards of professional ethics, education and attainments....” The ACS expects its volunteers and national meeting attendees to display the highest qualities of personal and professional integrity in all aspects of their ACS related activities. Indeed, every chemical professional has obligations to the public, to volunteer and staff colleagues, and to science.

    Accordingly, and to foster a positive environment built upon a foundation of trust, respect, open communications, and ethical behavior, the ACS Board of Directors has issued this Conduct Policy. It applies to ACS Volunteers, i.e., it applies to individuals conducting the business and affairs of the ACS without compensation for that conduct. It also applies to attendees at ACS national meetings. Volunteers and national meeting attendees should at all times abide by this Conduct Policy. Specifically:

    1. Volunteers should understand and support ACS’s vision and mission.
    2. Volunteers and national meeting attendees should contribute to a collegial, inclusive, positive, and respectful environment for their fellow volunteers and attendees, as well as for other stakeholders, including national meeting vendors and ACS staff.
    3. Volunteers and national meeting attendees must avoid taking any inappropriate actions based on race, gender, age, religion, ethnicity, nationality, sexual orientation, gender expression, gender identity, marital status, political affiliation, presence of disabilities, or educational background. They should show consistent respect to colleagues, regardless of the level of their formal education and whether they are from industry, government or academia, or other scientific and engineering disciplines.
    4. Volunteers and national meeting attendees should interact with others in a cooperative and respectful manner. Volunteers and national meeting attendees should refrain from using insulting, harassing, or otherwise offensive language in their ACS interactions. Disruptive, harassing, or inappropriate behavior toward other volunteers, stakeholders, or staff is unacceptable. Personal boundaries set by others must be observed. Harassment of any kind, including but not limited to unwelcome sexual advances, requests for sexual favors, and other verbal or physical harassment will not be tolerated.
    5. Volunteers must obey all applicable laws and regulations of the relevant government authorities while acting on behalf of the ACS. Likewise, national meeting attendees must obey all applicable laws and regulations of the relevant government authorities while attending ACS national meetings. Volunteers and national meeting attendees alike should also ensure that they comply with all applicable safety guidelines relating to public chemistry demonstrations.
    6. Volunteers and national meeting attendees should only use ACS’s trademarks, insignia, name, logos, and other intellectual property in compliance with ACS regulations and directives as may be issued from time to time.
    7. Violations of this Conduct Policy should be reported promptly to the ACS Secretary and General Counsel or to the Chair of the ACS Board of Directors. In cases of alleged persistent and/or serious violations of this Conduct Policy, the Board shall review the evidence and shall take such actions as may be appropriate, including but not limited to requiring volunteers to leave their volunteer position(s); precluding volunteers from serving in Society volunteer roles in the future; requiring national meeting attendees to leave the meeting; and, precluding meeting attendees from attending future ACS national meetings. ACS, through its Board of Directors, reserves the right to pursue additional measures as it may determine are appropriate.
