Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization and Basis of Presentation	Note 1 - Organization and basis of presentation: Organization At September 30, 2016, Valhi, Inc. (NYSE: VHI) held approximately 50% of our outstanding common stock and NL Industries, Inc. (NYSE: NL) held approximately 30% of our common stock, Valhi owned approximately 83% of NL’s outstanding common stock and a wholly-owned subsidiary of Contran Corporation held approximately 93% of Valhi’s outstanding common stock. All of Contran’s outstanding voting stock is held by a family trust established for the benefit of Lisa K. Simmons and Serena Simmons Connelly and their children, for which Ms. Simmons and Ms. Connelly are co-trustees, or is held directly by Ms. Simmons and Ms. Connelly or entities related to them. Consequently, Ms. Simmons and Ms. Connelly may be deemed to control Contran, Valhi, NL and us. Basis of presentation - The unaudited Condensed Consolidated Financial Statements contained in this Quarterly Report have been prepared on the same basis as the audited Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2015 that we filed with the Securities and Exchange Commission (SEC) on March 10, 2016 (2015 Annual Report). In our opinion, we have made all necessary adjustments (which include only normal recurring adjustments) in order to state fairly, in all material respects, our consolidated financial position, results of operations and cash flows as of the dates and for the periods presented. We have condensed the Consolidated Balance Sheet at December 31, 2015 contained in this Quarterly Report as compared to our audited Consolidated Financial Statements at that date, and we have omitted certain information and footnote disclosures (including those related to the Consolidated Balance Sheet at December 31, 2015) normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). Our results of operations for the interim periods ended September 30, 2016 may not be indicative of our operating results for the full year. The Condensed Consolidated Financial Statements contained in this Quarterly Report should be read in conjunction with our 2015 Consolidated Financial Statements contained in our 2015 Annual Report. Unless otherwise indicated, references in this report to “we,” “us” or “our” refer to Kronos Worldwide, Inc. and its subsidiaries (NYSE: KRO) taken as a whole.

Marketable Securities	Note 4 - Marketable securities: Our marketable securities consist of investments in the publicly-traded shares of related parties: Valhi, NL and CompX International Inc. NL owns the majority of CompX’s outstanding common stock. All of our marketable securities are accounted for as available-for-sale securities, which are carried at fair value using quoted market prices in active markets for each marketable security, and represent a Level 1 input within the fair value hierarchy. See Note 13. Because we have classified all of our marketable securities as available-for-sale, any unrealized gains or losses on the securities are recognized through other comprehensive income, net of deferred income taxes.

We also held a nominal number of shares of CompX and NL common stocks. At December 31, 2015 and September 30, 2016, the quoted per share market price of Valhi’s common stock was $1.34 and $2.30, respectively. The Valhi, CompX and NL common stocks we own are subject to the restrictions on resale pursuant to certain provisions of SEC Rule 144. In addition, as a majority-owned subsidiary of Valhi we cannot vote our shares of Valhi common stock under Delaware General Corporation law, but we do receive dividends from Valhi on these shares, when declared and paid.

Debt Disclosure [Abstract]
Long-Term Debt	Note 7 - Long-term debt: December 31, September 30, 2015 2016 (In millions) Term loan $ 338.0 $ 336.4 Revolving North American credit facility - 18.5 Other 3.0 3.1 Total debt 341.0 358.0 Less current maturities 3.8 22.0 Total long-term debt $ 337.2 $ 336.0 Term loan - During the first nine months of 2016, we made our required quarterly term loan principal payments aggregating $2.6 million. The average interest rate on the term loan borrowings as of and for the nine months ended September 30, 2016 was 4.0%. The carrying value of the term loan at September 30, 2016 is stated net of unamortized original issue discount of $1.0 million and debt issuance costs of $3.8 million. See Note 13 for a discussion of the interest rate swap we entered into in 2015 pursuant to our interest rate risk management strategy. Revolving North American credit facility - During the first nine months of 2016, we borrowed a net $18.5 million under our North American revolving credit facility. The average interest rate on outstanding borrowings as of and for the nine months ended September 30, 2016 was 4.25% and 4.13%, respectively. At September 30, 2016 we had approximately $57.4 million available for additional borrowing under this revolving facility. Revolving European credit facility - Our European revolving credit facility requires the maintenance of certain financial ratios, and one of such requirements is based on the ratio of net debt to last twelve months earnings before income tax, interest, depreciation and amortization expense (EBITDA) of the borrowers. Based upon the borrowers’ last twelve months EBITDA as of September 30, 2016 and the net debt to EBITDA financial test, our borrowing availability at September 30, 2016 is approximately 22% of the credit facility, or €26.4 million ($29.6 million). Other - We are in compliance with all of our debt covenants at September 30, 2016.

The amount shown on such table for incremental net tax expense (benefit) on earnings and losses on non-U.S. companies includes, as applicable, (i) current income taxes (including withholding taxes, if applicable), if any, associated with any current-year earnings of our non-U.S. subsidiaries to the extent such current-year earnings were distributed to us in the current year, (ii) deferred income taxes (or deferred income tax benefit) associated with the current-year change in the aggregate amount of undistributed earnings of our Canadian subsidiary, which earnings are not subject to a permanent reinvestment plan, in an amount representing the current-year change in the aggregate current income tax that would be generated (including withholding taxes, if applicable) when such aggregate undistributed earnings are distributed to us, and (iii) current U.S. income taxes (or current income tax benefit), including U.S. personal holding company tax, as applicable, attributable to current-year income (losses) of one of our non-U.S. subsidiaries, which subsidiary is treated as a dual resident for U.S. income tax purposes, to the extent the current-year income (losses) of such subsidiary is subject to U.S. income tax under the U.S. dual-resident provisions of the Internal Revenue Code. Tax authorities are examining certain of our U.S. and non-U.S. tax returns and have or may propose tax deficiencies, including penalties and interest. Because of the inherent uncertainties involved in settlement initiatives and court and tax proceedings, we cannot guarantee that these matters will be resolved in our favor, and therefore our potential exposure, if any, is also uncertain. As a result of ongoing audits in certain jurisdictions, in 2008 we filed Advance Pricing Agreement Requests with the tax authorities in the U.S., Canada and Germany. These requests have been under review with the respective tax authorities since 2008 and prior to the third quarter of 2016, it was uncertain whether an agreement would be reached between the tax authorities and whether we would agree to execute and finalize such agreements. During the third quarter of 2016, Contran, as the ultimate parent of our U.S. Consolidated income tax group, executed and finalized an Advance Pricing Agreement with the U.S. Internal Revenue Service and our Canadian subsidiary executed and finalized an Advance Pricing Agreement with the Competent Authority for Canada (collectively, the “U.S.-Canada APA”) effective for tax years 2005 - 2015. Pursuant to the terms of the U.S.-Canada APA, the U.S. and Canadian tax authorities agreed to certain prior year changes to taxable income of our U.S. and Canadian subsidiaries. As a result of such agreed-upon changes, we recognized a $5.6 million current U.S. income tax benefit in the third quarter of 2016. In addition, our Canadian subsidiary will incur a cash income tax payment of approximately CAD $3 million (USD $2.3 million) as a result of the U.S.-Canada APA, but such payment was fully offset by previously provided accruals (such USD $2.3 million has not been paid as of September 30, 2016, and is classified as part of income taxes payable at such date). We currently expect the Advance Pricing Agreement between Canada and Germany (collectively, the “Canada-Germany APA”) to be executed and finalized within the next twelve months. We believe we have adequate accruals to cover any cash income tax payment which might result from the finalization of the Canada-Germany APA, and accordingly we do not expect the execution of such APA to have a material adverse effect on our consolidated financial position, results of operations or liquidity. We have substantial net operating losses in Germany and Belgium, the benefit of which we had previously recognized under the more-likely-than-not recognition criteria. In the second quarter of 2015, we determined that such losses did not meet the more-likely-than-not recognition criteria, and as a result we recognized a non-cash deferred income tax expense of $150.3 million in the second quarter of 2015 as a valuation allowance against our net deferred income tax assets in such jurisdictions. We recognized an additional $2.3 million non-cash deferred income tax asset valuation allowance during the third quarter of 2015 and recognized an aggregate $2.1 million non-cash deferred income tax asset valuation allowance in the first nine months of 2016 (mostly in the second quarter) as additional valuation allowance against additional losses in such jurisdictions.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 12 - Commitments and contingencies: We are involved in various environmental, contractual, product liability, patent (or intellectual property), employment and other claims and disputes incidental to our business. At least quarterly our management discusses and evaluates the status of any pending litigation to which we are a party. The factors considered in such evaluation include, among other things, the nature of such pending cases, the status of such pending cases, the advice of legal counsel and our experience in similar cases (if any). Based on such evaluation, we make a determination as to whether we believe (i) it is probable a loss has been incurred, and if so if the amount of such loss (or a range of loss) is reasonably estimable, or (ii) it is reasonably possible but not probable a loss has been incurred, and if so if the amount of such loss (or a range of loss) is reasonably estimable, or (iii) the probability a loss has been incurred is remote. In March 2013, we were served with the complaint, Los Gatos Mercantile, Inc. d/b/a Los Gatos Ace Hardware, et al v. E.I. Du Pont de Nemours and Company, et al. (United States District Court, for the Northern District of California, Case No. 3:13-cv-01180-SI). The defendants include us, E.I. Du Pont de Nemours & Company, Huntsman International LLC and Millennium Inorganic Chemicals, Inc. As amended by plaintiffs’ third amended complaint (Harrison, Jan, et al v. E.I. Du Pont de Nemours and Company, et al), plaintiffs seek to represent a class consisting of indirect purchasers of titanium dioxide in the states of Arizona, Arkansas, California, the District of Columbia, Florida, Iowa, Kansas, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Nebraska, New Hampshire, New Mexico, New York, North Carolina, Oregon and Tennessee that indirectly purchased titanium dioxide from one or more of the defendants on or after March 1, 2002. The complaint alleges that the defendants conspired and combined to fix, raise, maintain, and stabilize the price at which titanium dioxide was sold in the United States and engaged in other anticompetitive conduct. The case is now proceeding in the trial court. We believe the action is without merit, will deny all allegations of wrongdoing and liability and intend to defend against the action vigorously. Based on our quarterly status evaluation of this case, we have determined that it is not reasonably possible that a loss has been incurred in this case. In September 2016, we were served with the complaint, Home Depot U.S.A., Inc. v. E.I. Dupont Nemours and Company, et al. (United States District Court, for the Northern District of California, Case No. 3:16-cv-04865). The defendants include us, E.I. Du Pont de Nemours & Company, Huntsman International LLC and Millennium Inorganic Chemicals, Inc. The plaintiff alleges that it indirectly purchased titanium dioxide from one or more of the defendants on or after March 1, 2002. The complaint alleges that the defendants conspired and combined to fix, raise, maintain, and stabilize the price at which titanium dioxide was sold in the United States and engaged in other anticompetitive conduct. The case is now proceeding in the trial court. We believe the action is without merit, will deny all allegations of wrongdoing and liability and intend to defend against the action vigorously. Based on our evaluation of this case, we have determined that it is not reasonably possible that a loss has been incurred in this case.

Fair Value Disclosures [Abstract]
Financial Instruments	Note 13 - Financial instruments: The following table summarizes the valuation of our financial instruments recorded on a fair value basis as of December 31, 2015 and September 30, 2016: Fair Value Measurements Quoted Significant prices in other Significant active observable unobservable markets inputs inputs Total (Level 1) (Level 2) (Level 3) (In millions) Asset (liability) December 31, 2015 Currency forward contracts $ (1.2 ) $ (1.2 ) $ - $ - Interest rate swap contract (3.5 ) - (3.5 ) - Noncurrent marketable securities (See Note 4) 2.4 2.4 - - September 30, 2016 Currency forward contracts $ .5 $ .5 $ - $ - Interest rate swap contract (8.1 ) - (8.1 ) - Noncurrent marketable securities (See Note 4) 4.0 4.0 - - Our earnings and cash flows are subject to fluctuations due to changes in currency exchange rates and interest rates. Our risk management policy allows for the use of derivative financial instruments to prudently manage exposure to foreign currency exchange rates and interest rates. Derivatives that we use are primarily currency forward contracts and interest rate swaps. We have not entered into these contracts for trading or speculative purposes in the past, nor do we currently anticipate entering into such contracts for trading or speculative purposes in the future. Currency forward contracts - Certain of our sales generated by our non-U.S. operations are denominated in U.S. dollars. We periodically use currency forward contracts to manage a very nominal portion of currency exchange rate risk associated with trade receivables denominated in a currency other than the holder’s functional currency or similar exchange rate risk associated with future sales. Derivatives used to hedge forecasted transactions and specific cash flows associated with financial assets and liabilities denominated in currencies other than the U.S. dollar and which meet the criteria for hedge accounting are designated as cash flow hedges. Consequently, the effective portion of gains and losses is deferred as a component of accumulated other comprehensive income and is recognized in earnings at the time the hedged item affects earnings. Contracts that do not meet the criteria for hedge accounting are marked-to-market at each balance sheet date with any resulting gain or loss recognized in income currently as part of net currency transaction gains and losses. The fair value of the currency forward contracts is determined using Level 1 inputs based on the currency spot forward rates quoted by banks or currency dealers. At September 30, 2016, we had currency forward contracts to exchange: • an aggregate €8.8 million for an equivalent value of Norwegian kroner at exchange rates ranging from krone 9.44 to krone 9.47 per euro. These contracts with DnB Nor Bank ASA and Deutsche Bank mature at a rate of approximately €2.9 million per month from October 2016 through December 2016; • an aggregate $6.5 million for an equivalent value of Norwegian kroner at exchange rates ranging from krone 8.31 to krone 8.32 per U.S. dollar. These contracts with DnB Nor Bank ASA mature at a rate of approximately $2.2 million per month from October 2016 through December 2016; • an aggregate $7.4 million for an equivalent value of Canadian dollars at an exchange rate of Cdn. $1.29 per U.S. dollar. These contracts with Wells Fargo Bank, N.A. mature at a rate of approximately $2.5 million per month from October 2016 through December 2016, and; • an aggregate $3.8 million for an equivalent value of euro at an exchange rate of €1.14 per U.S. dollar. These contracts with Deutsche Bank mature at a rate of $1.3 million per month from October 2016 through December 2016. The estimated fair value of such currency forward contracts at September 30, 2016 was a $.5 million net asset, including $.7 million recognized as part of accounts and other receivables and $.2 million recognized as part of accounts payable and accrued liabilities in our Condensed Consolidated Balance Sheet. We recognized a net $1.1 million currency transaction gain in our Condensed Consolidated Statement of Operations for the nine months ended September 30, 2016 related to currency forward contracts. We are not currently using hedge accounting for our outstanding currency forward contracts at September 30, 2016 and we did not use hedge accounting for any of such contracts we previously held in 2015. Accordingly, changes in the aggregate fair value of currency forward contracts we hold are recognized as a currency transaction gain or loss. Interest rate swap contract - As part of our interest rate risk management strategy, in August 2015 we entered into a pay- fixed/receive-variable interest rate swap contract with Wells Fargo Bank, N.A. to minimize our exposure to volatility in LIBOR as it relates to our forecasted outstanding variable-rate indebtedness. Under this interest rate swap, we will pay a fixed rate of 2.016% per annum, payable quarterly, and receive a variable rate of three-month LIBOR (subject to a 1.00% floor), also payable quarterly, in each case based on the notional amount of the swap then outstanding. The effective date of the swap contract was September 30, 2015. The notional amount of the swap started at $344.75 million and declines by $875,000 each quarter beginning December 31, 2015, with a final maturity of the swap contract in February 2020. The notional amount of the swap as of September 30, 2016 was $341.3 million. This swap contract has been designated as a cash flow hedge and qualified as an effective hedge at inception under ASC Topic 815. The effective portion of changes in fair value on this interest rate swap is recorded as a component of other comprehensive income, net of deferred income taxes. Commencing in the fourth quarter of 2015, as interest expense accrues on LIBOR-based variable rate debt, we classify the amount we pay under the pay-fixed leg of the swap and the amount we receive under the receive-variable leg of the swap as part of interest expense, with the net effect that the amount of interest expense we recognize on our LIBOR-based variable rate debt each quarter, as it relates to the notional amount of the swap outstanding each quarter, to be based on a fixed rate of 2.016% per annum in lieu of the level of LIBOR prevailing during the quarter. The amount of hedge ineffectiveness, if any, related to the swap will be recorded in earnings (also as part of interest expense). Since the inception of the swap through September 30, 2016, there have been no gains or losses recognized in earnings representing hedge ineffectiveness with respect to the interest rate swap. During the first nine months of 2016, the pretax amount recognized in other comprehensive income (loss) related to the interest rate swap contract was a $4.6 million loss. During the same period, $2.7 million was reclassified from accumulated other comprehensive loss into earnings (interest expense). During the next twelve months, the amount of the September 30, 2016 accumulated other comprehensive loss balance that is expected to be reclassified to interest expense is $3.5 million pre-tax. The fair value of the interest rate swap contract at September 30, 2016 was a liability of $8.1 million and is reflected in the Condensed Consolidated Balance Sheet as part of accounts payable and accrued liabilities ($3.3 million) and other noncurrent liabilities ($4.8 million). See Notes 6 and 10. The fair value of the interest rate swap was estimated by a third party using inputs that are observable or that can be corroborated by observable market data such as interest rate yield curves, and therefore, is classified within Level 2 of the valuation hierarchy. The following table presents the financial instruments that are not carried at fair value but which require fair value disclosure as of December 31, 2015 and September 30, 2016. December 31, 2015 September 30, 2016 Carrying amount Fair value Carrying amount Fair value (In millions) Cash, cash equivalents and restricted cash $ 94.3 $ 94.3 $ 93.3 $ 93.3 Long-term debt: Variable rate: Term loan 338.0 309.5 336.4 331.0 North American credit facility - - 18.5 18.5 Common stockholders' equity 461.9 653.6 454.9 960.8 At September 30, 2016, the estimated market price of our term loan was $970 per $1,000 principal amount. The fair value of our term loan is based on quoted market prices; however, these quoted market prices represented Level 2 inputs because the markets in which the term loan trades were not active. The fair value of our common stockholders’ equity is based upon quoted market prices at each balance sheet date, which represent Level 1 inputs. Due to their near-term maturities, the carrying amounts of accounts receivable, accounts payable and the revolving credit facility are considered equivalent to fair value. See Notes 2, 6 and 7.

(NYSE: NL) held approximately 30% of our common stock, Valhi owned approximately 83% of NL’s outstanding common stock and a wholly-owned subsidiary of Contran Corporation held approximately 93% of Valhi’s outstanding common stock. All of Contran’s outstanding voting stock is held by a family trust established for the benefit of Lisa K. Simmons and Serena Simmons Connelly and their children, for which Ms. Simmons and Ms. Connelly are co-trustees, or is held directly by Ms. Simmons and Ms. Connelly or entities related to them. Consequently, Ms. Simmons and Ms. Connelly may be deemed to control Contran, Valhi, NL and us.

U.S.-Canada Advance Pricing Agreement, description				Tax authorities are examining certain of our U.S. and non-U.S. tax returns and have or may propose tax deficiencies, including penalties and interest. Because of the inherent uncertainties involved in settlement initiatives and court and tax proceedings, we cannot guarantee that these matters will be resolved in our favor, and therefore our potential exposure, if any, is also uncertain. As a result of ongoing audits in certain jurisdictions, in 2008 we filed Advance Pricing Agreement Requests with the tax authorities in the U.S., Canada and Germany. These requests have been under review with the respective tax authorities since 2008 and prior to the third quarter of 2016, it was uncertain whether an agreement would be reached between the tax authorities and whether we would agree to execute and finalize such agreements. During the third quarter of 2016, Contran, as the ultimate parent of our U.S. Consolidated income tax group, executed and finalized an Advance Pricing Agreement with the U.S. Internal Revenue Service and our Canadian subsidiary executed and finalized an Advance Pricing Agreement with the Competent Authority for Canada (collectively, the “U.S.-Canada APA”) effective for tax years 2005 - 2015.
