Accounting Policies [Abstract] |
Basis of Accounting, Policy [Policy Text Block] | Business and Basis of Presentation The consolidated financial statements include the accounts of LiqTech International, Inc., (the “Company”) and its subsidiaries. The terms "Company", “us", "we" and "our" as used in this report refer to the Company and its subsidiaries, which are set forth below in Item 2, the management's discussion and analysis section. The Company engages in the development, design, production, marketing and sale of automated filtering systems, ceramic silicon carbide membrane applications and diesel particulate air filters in North America, Europe, Asia, Australia, and South America. These interim consolidated financial statements are unaudited. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These Condensed Consolidated Financial Statements should be read in conjunction with our financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2022. The results of operations for the period ended June 30, 2023 are not necessarily indicative of the operating results for the full year and are unaudited. In the opinion of management, all adjustments consisting of a normal recurring nature and necessary for a fair presentation have been included.
Consolidation, Policy [Policy Text Block] | Consolidation -- The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries and its majority-owned subsidiary. All material intercompany transactions and accounts have been eliminated in the consolidation.
Reverse Stock Split [Policy Text Block] | Reverse Stock Split -- On May 26, 2023, the Company effected a 1-for-8 reverse split of its outstanding Common Stock. All outstanding Common Stock, warrants, and RSUs were adjusted to reflect the 1-for-8 reverse split, with respective exercise prices of the warrants proportionately increased. All stock and per share data throughout these condensed consolidated financial statements have been retroactively adjusted to reflect the reverse share split. The total number of authorized Common Stock was adjusted to reflect the 1-for-8 reverse split. As a result of the reverse Common Stock split, an amount equal to the decreased value of Common Stock was reclassified from “Common Stock” to “additional paid-in capital.”
Reclassification, Comparability Adjustment [Policy Text Block] | Reclassification – Certain amounts presented in previously issued financial statements have been reclassified to be consistent with the current period presentation. In the statement of operations and comprehensive loss, the Company has reclassified the prior year comparative amounts of general and administrative expenses and other expenses to be consistent with the current classification.
Foreign Currency Transactions and Translations Policy [Policy Text Block] | Functional Currency / Foreign currency translation -- The functional currency of LiqTech International, Inc., LiqTech USA, Inc. and LiqTech NA is the U.S. Dollar. The functional currency of LiqTech Holding, LiqTech Water, LiqTech Plastics, LiqTech Ceramics, LiqTech Water Projects and LiqTech Emission Control is the Danish Krone (“DKK”); the functional currency of LiqTech China is the Renminbi (“RMB”); and the functional currency of LiqTech Singapore is the Singapore Dollar. The Company’s reporting currency is the U.S. Dollar for the purpose of these consolidated financial statements. The balance sheet accounts of the foreign subsidiaries are translated into U.S. Dollars at the period-end exchange rates, and all revenue and expenses are translated into U.S. Dollars at the average exchange rates prevailing during the six months ended June 30, 2023 and 2022. Translation gains and losses are deferred and accumulated as a component of other comprehensive income (loss) in stockholders’ equity. Transaction gains and losses that arose from exchange rate fluctuations from transactions denominated in a currency other than the functional currency are included in the statement of operations as incurred.
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash and Restricted Cash -- The Company considers all highly liquid debt instruments purchased with a maturity of three months or less to be cash equivalents. As of June 30, 2023, and December 31, 2022, the Company held $1,469,032 and $1,440,394, respectively, of restricted cash. The restricted cash is held as security by a local financial institution against a leasing facility and for bank guarantees issued for the benefit of customers in connection with prepayments of sales orders and general product warranties. Accounts held in each U.S. institution are insured by the Federal Deposit Insurance Company (“FDIC”) up to $250,000. At June 30, 2023 and December 31, 2022 the Company had $14,711, and $12,999,271 in excess of the FDIC insured limit, respectively.
Accounts Receivable [Policy Text Block] | Accounts Receivable -- Accounts receivable consist of trade receivables arising in the normal course of business. The Company establishes an allowance for doubtful accounts that reflects the Company’s best estimate of probable losses inherent in the accounts receivable balance. The Company determines the allowance based on known troubled accounts, historical experience, age, financial information that is publicly accessible and other currently available evidence. The roll-forward of the allowance for doubtful accounts for the periods ended June 30, 2023 and December 31, 2022 is as follows:
|  | June 30, 2023 |  |  | December 31, 2022 |
Allowance for doubtful accounts at the beginning of the period |  | $ | 59,559 |  |  | $ | 409,076 |
Bad debt expense |  |  | - |  |  |  | (24,534 | )
Receivables written off during the periods |  |  | (10,299 | ) |  |  | (295,778 | )
Effect of currency translation |  |  | 970 |  |  |  | (29,205 | )
Allowance for doubtful accounts at the end of the period |  | $ | 50,230 |  |  | $ | 59,559 |
Inventory, Policy [Policy Text Block] | Inventory – Inventory directly purchased is carried at the lower of cost or net realizable value, as determined on the first-in, first-out (“FIFO”) method. For inventory produced, standard costs that approximate actual costs, applying the FIFO method, are used to value inventory. Standard costs are reviewed at least annually by management or more often in the event that circumstances indicate a change in cost has occurred. Work in process and finished goods include material, labor, and production overhead costs. The Company adjusts the value of its inventory to the extent management determines that the cost cannot be recovered due to obsolescence or other factors. Inventory valuation adjustments for excess and obsolete inventory are calculated based on current inventory levels, movement, expected useful lives, and estimated future demand of the products and spare parts.
Receivable [Policy Text Block] | Contracts Assets / Liabilities – Contract assets are the Company’s rights to consideration in exchange for goods or services and are recognized when a performance obligation has been satisfied but has not yet been billed. When the Company issues invoices to the customer and the billing is higher than the capitalized Contract assets, the net amount is transferred to Contract liabilities. Contract assets/liabilities are transferred to revenue and cost of goods sold when the right to consideration is unconditional and billed per the terms of the contractual agreement. Contract assets also include unbilled receivables, which usually comprise the last invoice remaining after the delivery of the water treatment unit, where revenue is recognized at the transfer of control based upon signed acceptance of the water treatment unit by the customer. Most commonly this invoice is sent to the customer at commissioning of the product or no later than 12 months after the delivery. Also included in Contract assets are short-term receivables such as value-added tax (VAT) and other receivables.
Assets Held for Sale [Policy Text Block] | Assets Held for Sale -- Assets are classified as held for sale when all of the following criteria for a plan of sale have been met: (1) management, having the authority to approve the action, commits to a plan to sell the assets; (2) the assets are available for immediate sale, in their present condition, subject only to terms that are usual and customary for sales of such assets; (3) an active program to locate a buyer and other actions required to complete the plan to sell the assets have been initiated; (4) the sale of the assets is probable and is expected to be completed within one year; (5) the assets are being actively marketed for a price that is reasonable in relation to their current fair value; and (6) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or the plan will be withdrawn. When all of these criteria have been met, the assets are classified as held for sale on the balance sheet. Assets classified as held for sale are reported at the lower of their carrying value or fair value less costs to sell. Depreciation and amortization of assets ceases upon designation as held for sale.
Lessee, Leases [Policy Text Block] | Leases -- The Company has elected to not recognize lease assets and liabilities with an initial term of 12 months or less and to not separate lease and non-lease components. The Company’s accounting for finance leases remains substantially unchanged. Operating lease right-of-use (“ROU”) assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, an incremental borrowing rate based on the information available at the commencement date is used in determining the present value. The Company will use the implicit rate when readily determinable. The operating lease ROU asset also includes prepaid lease payments, reduced by accrued lease payments. The Company’s lease terms may include options to extend or terminate the lease, for which the Company will reflect the change when it is reasonably certain that those options will be exercised. Operating lease cost for lease payments will be recognized on a straight-line basis over the lease term.
Property, Plant and Equipment, Policy [Policy Text Block] | Property and Equipment -- Property and equipment are stated at cost. Expenditures for major renewals and betterments that extend the useful lives of property and equipment are capitalized upon being placed in service. Expenditures for maintenance and repairs are charged to expense as incurred. Depreciation is computed for financial statement purposes on a straight-line basis over the estimated useful lives of the assets, which range from three to ten years.
Goodwill and Intangible Assets, Policy [Policy Text Block] | Goodwill and Intangible Assets -- The purchase price of an acquired company is allocated between intangible assets and the net tangible assets of the acquired business, with the residual purchase price recorded as goodwill. The determination of the value of the intangible assets acquired involves certain judgments and estimates. These judgments can include, but are not limited to, the cash flows that an asset is expected to generate in the future and the appropriate weighted average cost of capital. Acquired intangible assets with determinable useful lives are amortized on a straight-line or accelerated basis over the estimated periods benefited, ranging from one to ten years. Customer relationships and other non-contractual intangible assets with determinable lives are amortized over periods of five years. The Company evaluates the recoverability of long-lived assets by comparing the carrying amount of an asset to estimated future net undiscounted cash flows generated by the asset. If such assets are considered to be impaired, the impairment recognized is measured as the amount by which the carrying value of the assets exceeds the fair value of the assets. The evaluation of recoverability involves estimates of future operating cash flows based upon certain forecasted assumptions, including, but not limited to, revenue growth rates, gross profit margins, and operating expenses over the expected remaining useful life of the related asset. A shortfall in these estimated operating cash flows could result in an impairment charge in the future. Goodwill is not amortized but is evaluated annually for impairment at the reporting unit level or when indicators of a potential impairment are present. The Company estimates the fair value of the reporting unit using the discounted cash flow and market approaches. Forecasts of future cash flows are based on the Company’s best estimate of future net sales and operating expenses, using primarily expected category expansion, pricing, market segment fundamentals, and general economic conditions.

Corporate |  |  | 2,801 |  |  |  | 26,242 |  |  |  | 2,801 |  |  |  | 51,772 |
|  | $ | 4,990,019 |  |  | $ | 5,018,292 |  |  | $ | 9,001,538 |  |  | $ | 8,655,528 |
For Water (systems and aftermarket), Ceramics (diesel particulate filters and membranes), and Plastics (components), revenue is recognized when performance obligations specified within the terms of a contract with the customer are satisfied, which occurs when control of the product transfers to the customer or when services are rendered by the Company. The majority of the Company's sales contracts contain performance obligations satisfied at a point in time when title along with risks and rewards of ownership have transferred to the customer. This generally occurs when the product is shipped or accepted by the customer. Revenue for service contracts is recognized as the services are provided. Revenue is measured as the amount of consideration expected to be received in exchange for transferring the goods or providing services. The satisfaction of performance obligations under the terms of a revenue contract generally gives rise to the right to receive payment from the customer. The Company's standard payment terms vary by the type and location of the customer and the products or services offered. Generally, the time between when revenue is recognized and when payment is due is not significant. Pre-payments received prior to satisfaction of performance obligations are recorded as a Contract liability. Considering the relatively short time between revenue recognition and receipt of payment, financing components do not exist between the Company and its customers. For contracts with customers that include multiple performance obligations, judgment is required to determine whether performance obligations specified in these contracts are distinct and should be accounted for as separate revenue transactions for recognition purposes. For such arrangements, revenue is allocated to each performance obligation based on its relative standalone selling price. Standalone selling prices are generally determined based on the prices charged to customers or using expected cost-plus margin. System sales are recognized when the Company transfers control to the customer based upon sales and delivery conditions specified in the sales contract. This typically occurs upon shipment of the system from the production facility but can also occur upon other agreed delivery terms. In connection with the completion of the system, it is normal procedure to issue a FAT (Factory Acceptance Test) asserting that the customer has accepted the performance of the system as it is being shipped from our production facility in Hobro. As part of the performance obligation, the customer is normally offered commissioning services (final assembly and configuration at a place designated by the customer), and this commissioning is therefore considered a second performance obligation and is valued at cost, with the addition of a standard gross margin. This second performance obligation is recognized as revenue at the time the commissioning services are being rendered together with the cost incurred. Part of the invoicing to the customer is also attributed to the commissioning, and at transfer of the control of the system (i.e., the first performance obligation), this portion is recognized as Contract liabilities. Aftermarket sales represent spare parts, extended warranties, commissionings, and maintenance services. For the sale of aftermarket parts, the Company transfers control and recognizes revenue when parts are shipped to the customer. When customers are given the right to return eligible parts and accessories, the Company estimates the expected returns based on an analysis of historical experience. The Company adjusts estimated revenues at the earlier of when the most likely amount of consideration expected to be received changes or when the consideration becomes fixed. The Company recognizes revenue for extended warranty and maintenance agreements based on the standalone selling price over the life of the contract. The Company has received long-term contracts for grants from government entities for the development and use of silicon carbide membranes in various water filtration and treatment applications and historically in the installation of various water filtration systems. We measure the transfer of control of the performance obligation on long-term contracts utilizing the cost-to-cost measure of progress, with cost of revenue including direct costs such as labor and materials. Under the cost-to-cost approach, the use of estimated costs to complete each performance obligation is a significant variable in the process of determining recognized revenue and a significant factor in the accounting for such performance obligations. The timing of when we bill our customers is generally dependent upon advance billings terms, milestone billings based on completion of certain phases of the work, or when services are provided or products are shipped. Projects with performance obligations recognized over time that have costs and estimated earnings recognized to date in excess of cumulative billings are reported on our balance sheet as Contract assets. Projects with performance obligations recognized over time that have cumulative billings in excess of costs and estimated earnings recognized to date are reported on our balance sheet as Contract liabilities. The roll-forward of Contract assets / liabilities for the periods ended June 30, 2023 and December 31, 2022 is as follows:
|  | June 30, 2023 |  |  | December 31, 2022 |
Cost incurred |  | $ | 4,018,416 |  |  | $ | 3,860,179 |
Unbilled project deliveries |  |  | 639,790 |  |  |  | 950,105 |
VAT |  |  | 448,695 |  |  |  | 229,006 |
Other receivables |  |  | 96,919 |  |  |  | 45,814 |
Prepayments |  |  | (3,620,906 | ) |  |  | (3,363,039 | )
Deferred Revenue |  |  | (54,713 | ) |  |  | (118,327 | )
|  | $ | 1,528,201 |  |  | $ | 1,603,738 |
Distributed as follows: |  |  |  |  |  |  |  |

|  | $ | 1,528,201 |  |  | $ | 1,603,738 |
Advertising Cost [Policy Text Block] | Advertising Cost -- Costs incurred in connection with advertising of the Company’s products are expensed as incurred. Advertising costs are included in sales expenses, and total advertising costs for the three-month periods ended June 30, 2023 and 2022 were $12,167 and $47,904, respectively. Total advertising costs amounted to $44,766 and $103,428 for the six months ended June 30, 2023 and 2022, respectively.
Research and Development Expense, Policy [Policy Text Block] | Research and Development Cost -- The Company expenses research and development costs as incurred. Included in operating expense for the three-month periods ended June 30, 2023, and 2022 were research and development costs of $359,784 and $490,836, respectively. For the six-month periods ended June 30, 2023, and 2022, research and development costs were $702,403 and $1,093,573, respectively.
Income Tax, Policy [Policy Text Block] | Income Taxes -- The Company accounts for income taxes in accordance with FASB ASC Topic 740, Accounting for Income Taxes. This statement requires an asset and liability approach with respect to accounting for income taxes.
Earnings Per Share, Policy [Policy Text Block] | Income/(Loss) Per Share -- The Company calculates earnings (loss) per share in accordance with FASB ASC 260, Earnings Per Share. Basic earnings per common share (EPS) are based on the weighted average number of shares of Common Stock outstanding during each period. Diluted earnings per common share are based on shares outstanding (computed as under basic EPS) and potentially dilutive common shares. Potential shares of Common Stock included in the diluted earnings per share calculation include in-the-money stock options, RSUs and warrants that have been granted but have not yet been exercised.
Share-Based Payment Arrangement [Policy Text Block] | Stock Awards -- During the years presented in the accompanying consolidated financial statements, the Company has granted stock awards. The Company accounts for stock awards in accordance with the provisions of FASB ASC Topic 718, Compensation – Stock Compensation.
Fair Value Measurement, Policy [Policy Text Block] | Fair Value of Financial Instruments -- The Company accounts for fair value measurements for financial assets and liabilities in accordance with FASB ASC Topic 820. The authoritative guidance, which among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or non-recurring basis. Fair value is defined as the exit price, representing the amount that would either be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:
● | Level 1. Observable inputs such as quoted prices in active markets for identical assets or liabilities;
● | Level 2. Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and
● | Level 3. Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.
Unless otherwise disclosed, the fair value of the Company’s financial instruments including cash, accounts receivable, other receivables, prepaid expenses, accounts payable, accrued expenses, convertible notes payable, and senior promissory notes payable approximate their recorded values due to their short-term maturities.
Use of Estimates, Policy [Policy Text Block] | Accounting Estimates -- The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets including accounts receivable; allowance for doubtful accounts; contract assets; reserve for excess and obsolete inventory; depreciation and impairment of property, plant and equipment; goodwill; liabilities including contract liabilities and contingencies; the disclosures of contingent assets and liabilities at the date of the financial statements; and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimated.
New Accounting Pronouncements, Policy [Policy Text Block] | Recent Accounting Pronouncements -- Recent accounting pronouncements issued by the FASB did not or are not believed by management to have a material impact on the Company’s present or future financial statements.
