| Spinoff [Abstract] | ||||
| Spinoff Activities, Description | On October 1, 2016 the Company completed the tax-free spin-off of its Resins and Chemicals business, part of Performance Materials and Technologies, into a standalone, publicly-traded company (named AdvanSix) to Honeywell shareowners. Since the effective date of the spin-off falls within the fiscal third quarter, the assets and liabilities associated with AdvanSix have been removed from the Company’s third quarter Consolidated Balance Sheet. The results of operations for AdvanSix are included in the Consolidated Statement of Operations through the effective date of the spin-off. See Note 1 Basis of Presentation of Notes to Financial Statements for further discussion of the Company’s actual quarterly closing date convention. Honeywell shareowners of record as of the close of business on September 16, 2016 received one share of AdvanSix common stock for every 25 shares of Honeywell common stock. Immediately prior to the effective date of the spin-off, AdvanSix incurred debt to make a cash distribution of $269 million to the Company. At the same time, AdvanSix also incurred $38 million of borrowings in order to fund its post spin-off working capital. | |||
