Line of Credit Facility [Line Items]
Borrowing capacity description					The Credit Agreement does not restrict our ability to pay dividends and contains no financial covenants. The failure to comply with customary conditions or the occurrence of customary events of default contained in the Credit Agreement would prevent any further borrowings and would generally require the repayment of any outstanding borrowings under the Credit Agreement. Such events of default include: (a) non-payment of Credit Agreement debt, interest or fees; (b) non-compliance with the terms of the Credit Agreement covenants; (c) cross-default with other debt in certain circumstances; (d) bankruptcy or insolvency; and (e) defaults upon obligations under the Employee Retirement Income Security Act. Additionally, each of the banks has the right to terminate its commitment to lend additional funds or issue letters of credit under the Credit Agreement if any person or group acquires beneficial ownership of 30 percent or more of our voting stock, or, during any 12-month period, individuals who were directors of Honeywell at the beginning of the period cease to constitute a majority of the Board of Directors.
Maximum borrowing capacity				4,500,000,000	4,500,000,000	3,000,000,000
Sub-Limit for Letters of Credit				700,000,000	700,000,000
Facility expiration date					Dec. 10, 2018

Interest rates applied to borrowings					Revolving credit borrowings under the Credit Agreement would bear interest, at Honeywell's option, (A) (1) at a rate equal to the highest of (a) the floating base rate publicly announced by Citibank, N.A., (b) 0.5 percent above the Federal funds rate or (c) LIBOR plus 1.00 percent, plus (2) a margin based on Honeywell's credit default swap mid-rate spread and subject to a floor and a cap as set forth in the Credit Agreement (the "Applicable Margin") minus 1.00 percent, provided such margin shall not be less than zero; or (B) at a rate equal to LIBOR plus the Applicable Margin; or (C) by a competitive bidding procedure.
