Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation [Text Block]	In the opinion of management, the accompanying unaudited Consolidated Financial Statements reflect all adjustments, consisting only of normal recurring adjustments, necessary to present fairly the financial position of Honeywell International Inc. and its consolidated subsidiaries (Honeywell or the Company) at June 30, 2021, and December 31, 2020, the cash flows for the six months ended June 30, 2021 and 2020, the results of operations for the three and six months ended June 30, 2021 and 2020, and the shareowners' equity for the three and six months ended June 30, 2021 and 2020. The results of operations for the three and six months ended June 30, 2021, and cash flows for the six months ended June 30, 2021, should not necessarily be taken as indicative of the entire year.Honeywell reports its quarterly financial information using a calendar convention; the first, second and third quarters are consistently reported as ending on March 31, June 30 and September 30. It has been Honeywell's practice to establish actual quarterly closing dates using a predetermined fiscal calendar, which requires Honeywell's businesses to close their books on a Saturday in order to minimize the potentially disruptive effects of quarterly closing on our business processes. The effects of this practice are generally not significant to reported results for any quarter and only exist within a reporting year. In the event that differences in actual closing dates are material to year-over-year comparisons of quarterly or year-to-date results, Honeywell will provide appropriate disclosures. Honeywell's actual closing dates for the three and six months ended June 30, 2021, and June 30, 2020, were July 3, 2021, and June 27, 2020, respectively.
