Segment Reporting [Abstract]  
SEGMENT INFORMATION SEGMENT AND REGIONAL SALES INFORMATION
Eastman's products and operations are managed and reported in four operating segments: Advanced Materials ("AM"), Additives & Functional Products ("AFP"), Chemical Intermediates ("CI"), and Fibers. The economic factors that impact the nature, amount, timing, and uncertainty of revenue and cash flows vary among the Company's operating segments and the geographical regions in which they operate. "Other" includes sales and costs related to growth initiatives, including the cellulosics biopolymer platform and circular economy, research and development ("R&D") costs, certain components of pension and other postretirement benefits, and other expenses and income not identifiable to an operating segment and is not included in operating segment results. This operating segment structure is used by the Chief Operating Decision Maker ("CODM"), who has been determined to be the Chief Executive Officer, to make key operating decisions and assess performance of the Company. The CODM evaluates segment operating performance, and makes resource allocation and performance evaluation decisions, based on Adjusted EBIT, defined as the GAAP measure earnings before interest and taxes ("EBIT"), adjusted for non-core, unusual, or non-recurring items. These adjustments allow the CODM to evaluate segment operating performance excluding the effect of transactions, costs, and losses or gains that do not directly result from Eastman's normal, or "core", business and operations, or are otherwise of an unusual or non-recurring nature.

Advanced Materials Segment

In the AM segment, the Company produces and markets polymers, films, and plastics with differentiated performance properties for value-added end-uses in transportation; durables and electronics; building and construction; medical and pharma; and consumables end-markets.

The advanced interlayers product line includes polyvinyl butyral sheet and polyvinyl butyral intermediates. The performance films product line primarily consists of window films and protective films products for aftermarket applied films. The specialty plastics product line consists of two primary products: copolyesters and cellulosic biopolymers.

Additives & Functional Products Segment

In the AFP segment, the Company manufactures materials for products in the food, feed, and agriculture; transportation; water treatment and energy; personal care and wellness; building and construction; consumables; and durables and electronics end-markets.

The care additives product line consists of amine derivative-based building blocks and organic acid-based solutions for the production of flocculants, intermediates for surfactants, fumigants, fungicides, and plant growth regulator products. The coatings additives product line can be broadly classified as polymers and additives and solvents and include specialty coalescents, specialty solvents, paint additives, and specialty polymers. The functional amines product lines include methylamines and salts, and higher amines and solvents. In the specialty fluids product line, the Company produces heat transfer and aviation fluids products.

Chemical Intermediates Segment

Eastman leverages large scale and vertical integration from the cellulosic biopolymers and acetyl and olefins streams to support the Company's specialty operating segments with advantaged cost positions. The CI segment sells excess intermediates beyond the Company's internal specialty needs into end-markets such as industrial chemicals and processing, building and construction, health and wellness, and food and feed.

The intermediates product line produces olefin derivatives, acetyl derivatives, ethylene, and commodity solvents. The plasticizers product line consists of a unique set of primary non-phthalate and phthalate plasticizers and a range of niche non-phthalate plasticizers.
