Accounting Policies [Abstract]
Basis of Accounting	The accompanying unaudited consolidated financial statements of Preformed Line Products Company and subsidiaries (the “Company” or “PLPC”) have been prepared in accordance with United States ("U.S.") generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. This Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in our Form 10-K for the year ended December 31, 2023 filed on March 8, 2024 with the Securities and Exchange Commission. The interim period results are not necessarily indicative of the results to be expected for the full year. Management has evaluated subsequent events through the date this Form 10-Q was filed with the Securities and Exchange Commission.
Use of Estimates	The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and the accompanying notes. Actual results could differ from these estimates. In the opinion of management, these consolidated financial statements contain all estimates and adjustments, consisting of normal recurring accruals, required to fairly present the financial position, results of operations, and cash flows for the interim periods. Operating results for the three and nine months ended September 30, 2024 are not necessarily indicative of the results to be expected for the full-year ending December 31, 2024.
Noncontrolling Interest	Noncontrolling interests are presented in the Company’s consolidated financial statements as if parent company investors (controlling interests) and other minority investors (noncontrolling interests) in partially-owned subsidiaries have similar economic interests in a single entity. As a result, investments in noncontrolling interests are reported as equity in the Company’s consolidated financial statements. Additionally, the Company’s consolidated financial statements include 100% of a controlled subsidiary’s earnings, rather than only its share. Transactions between the parent company and noncontrolling interests are reported in equity as transactions between stockholders, provided that these transactions do not create a change in control.
Reclassification	Certain prior year amounts have been reclassified to conform to the current year presentation.
Recently Adopted or Issued Accounting Pronouncements	In November 2023, the FASB issued Accounting Standards Update ("ASU") No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” This ASU enhances reportable segment disclosures on both an annual and interim basis primarily in regards to the disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (CODM) and included within the reported measure(s) of segment profit or loss. In addition, the ASU requires disclosure, by segment, of other items included in the reported measure(s) of segment profit or loss, including qualitative information describing the composition, nature and type of each item. The ASU also expands disclosure requirements related to the CODM, including how the reported measure(s) of segment profit or loss are used to assess segment performance and allocate resources, the method used to allocate overhead for significant segment expenses and others. Lastly, all current required annual segment reporting disclosures under Topic 280 are now effective for interim periods. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is evaluating the impact of adopting this ASU and expects the standard will only impact its segment disclosures with no material impact to the consolidated financial statements. In December 2023, the FASB issued Accounting Standards Update No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” This ASU enhances income tax disclosures by providing information to better assess how an entity's operations, related tax risks, tax planning and operational opportunities affect its tax rate and prospects for future cash flows. This ASU requires additional disclosures to the annual effective tax rate reconciliation including specific categories and further disaggregated reconciling items that meet the quantitative threshold. Additionally, the ASU requires disclosures relating to income tax expense and payments made to federal, state, local and foreign jurisdictions. This ASU is effective for fiscal years and interim periods beginning after December 15, 2024. The Company is evaluating the impact of adopting this ASU and expects the standard will only impact its income tax disclosures with no material impact to the consolidated financial statements.
Revenue Recognition	Sales are recognized when obligations under the terms of the contract are satisfied and control of promised goods or services have transferred to our customers. Control is transferred when the customer has the ability to direct the use of and obtain benefits from the goods or services and is primarily based on shipping terms. Sales are measured as the amount of consideration the Company expects to receive in exchange for transferring products.
Credit Losses for Receivables	The Company maintains an allowance for credit losses for estimated losses resulting from the inability of its customers to make required payments. The Company uses a current expected credit loss model in order to immediately recognize an estimate of credit losses that are expected to occur over the life of the financial instruments, mainly trade receivables. Additionally, the allowance is based upon identified delinquent accounts, customer payment patterns and other analyses of historical data trends. Receivable balances are written off against an allowance for credit losses after a final determination has been made.
Inventories, net	Inventory is carried at lower of cost or net realizable value.Costs for inventories of certain material, mainly in the U.S., are determined using the Last-In First-Out ("LIFO") method and totaled approximately $48.8 million at September 30, 2024 and $60.1 million at December 31, 2023. An actual valuation of inventories under the LIFO method can be made only at the end of the year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels and costs. Because these estimates are subject to change and may be different than the actual inventory levels and costs at the end of the year, interim results are subject to the final year-end LIFO inventory valuation.
Contingent Liabilities	Although the outcomes of these matters are not predictable with certainty, the Company records a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. In the event the Company determines that a loss is not probable, but is reasonably possible, and the likelihood to develop what the Company believes to be a reasonable range of potential loss exists, the Company will include disclosure related to such matters. To the extent that there is a reasonable possibility the losses could exceed amounts already accrued, the Company will adjust the accrual in the period in which the determination is made, disclose an estimate of the additional loss or range of loss and if the amount of such adjustment cannot be reasonably estimated, disclose that an estimate cannot be made.
Goodwill	The Company’s measurement date for its annual impairment test for goodwill is October 1st of each year. The Company performs additional interim impairment assessments as circumstances warrant. There were no indicators of impairment noted for the period ending September 30, 2024. The Company may use both quantitative and qualitative approaches when testing goodwill for impairment. For selected reporting units where the qualitative approach is utilized, a qualitative evaluation of events and circumstances impacting the reporting unit is performed to determine if it is more likely than not that the fair value of the reporting unit exceeds its carrying amount. If that determination is made, no further evaluation is necessary. Otherwise, the Company performs a quantitative impairment test on the reporting unit. For the quantitative approach, the Company uses a combination of the income approach, which uses a discounted cash flow methodology, and the market approach, which uses comparable market multiples in computing fair value by reporting unit. The Company then compares the fair value of the reporting unit with its carrying value to assess if goodwill has been impaired. The fair value estimates are subjective and sensitive to significant assumptions, such as revenue growth rates, operating margins, the weighted average cost of capital, and estimated market multiples, of which are affected by expectations of future market or economic conditions. The Company believes that the methodologies, significant assumptions, and weightings used are reasonable and result in appropriate fair values of the reporting units.
Fair Value of Financial Assets and Liabilities	Fair value is measured based on an exit price, representing the amount that would be received to sell an asset or paid to satisfy a liability in an orderly transaction between market participants. The Company measures and records certain assets and liabilities at fair value. A fair value hierarchy is used for those assets and liabilities measured at fair value that distinguishes between assumptions based on market data (observable inputs), and the Company’s assumptions (unobservable inputs). The hierarchy consists of the following three levels: (Level 1 Inputs) quoted market prices in active markets for identical assets or liabilities; (Level 2 Inputs) observable market-based inputs or unobservable inputs that are corroborated by market data; and (Level 3 Inputs) unobservable inputs that are not corroborated by market data. These amounts are recorded within Other noncurrent liabilities on the Company’s Consolidated Balance Sheets. The Supplemental Profit Sharing Plan allows participants the ability to hypothetically invest their proportionate award into various investment options, which primarily includes mutual funds. The Company credits earnings, gains and losses to the participants’ deferred compensation account balances based on the investments selected by the participants. The Company measures the fair value of the Supplemental Profit Sharing Plan liability using the market values of the participants’ underlying investment accounts. The carrying value of the Company’s current financial instruments, which include cash, cash equivalents and restricted cash, accounts receivable, accounts payable and short-term debt, approximates fair value because of the short-term maturity of these instruments. At September 30, 2024 and December 31, 2023, the fair value of the Company’s long-term debt was estimated using discounted cash flows analyses, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements that are considered to be Level 2 inputs.
Derivative Financial Instruments	The Company operates internationally and enters into intercompany transactions denominated in foreign currencies. Consequently, the Company is subject to market risk arising from exchange rate movements between the dates foreign currency transactions occur and the dates they are settled. The Company currently uses foreign currency forward contracts to reduce the risk related to some of these transactions. These contracts usually have maturities of 90 days or less and generally require an exchange of foreign currencies for U.S. dollars at maturity at rates stated in the contracts. These contracts are not designated as hedging instruments under U.S. GAAP. Accordingly, the changes in the fair value of the foreign currency forward contracts are recognized in each accounting period in Other operating expense, net on the Consolidated Statements of Income together with the transaction gain or loss from the related balance sheet position.
