The opportunity is a request for quotation to supply materials and/or services to Argonne National Laboratory. Offerors must review the applicable terms and conditions, complete the required representations and certifications, and provide a published price list or redacted invoice to support price reasonableness. Quotations must include the country of origin, confirm shipping terms (including HTS code for international shipments), and state the lead time. Any tariff charges must be included in the unit price, as separate tariff line items are not allowable. The response must also indicate whether any DOE discounts or GSA contract pricing apply, with the contract number and expiration date if applicable.
