Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of Estimates, Policy	Use of estimates The preparation of the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Recent Accounting Pronouncements	Recent accounting pronouncements Any recent accounting pronouncements are not expected to have a material impact on our condensed financial statements.
Consolidation, Policy		Principles of consolidation The accompanying consolidated financial statements include the accounts of the Company and its controlled subsidiaries, High Plains Partners, LLC, HPP SD Holdings, LLC, and High Plains Processing, LLC. All significant intercompany accounts and transactions have been eliminated in consolidation.
Receivable	Receivables and Credit Policies Accounts receivable are considered past due when payments are not received on a timely basis in accordance with the Company’s credit terms, which are generally thirty to sixty days from invoice date. Accounts considered uncollectible are written off. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering customers' financial condition, credit history, current and future economic conditions, and unusual circumstances, if any. The valuation allowance was determined to be immaterial as of June 30, 2025 and December 31, 2024, respectively.
Revenue from Contract with Customer	Revenue The Company accounts for all its revenues from contracts with customers under ASC 606, Revenue from Contracts with Customers. The Company principally generates revenue from merchandising and transporting manufactured agricultural products used as ingredients in food, feed, energy, and industrial products. Revenue is measured based on the consideration specified in the contract with a customer and excludes any amounts collected on behalf of third parties (e.g. - taxes). The Company follows a policy of recognizing revenue at a single point in time when it satisfies its performance obligation by transferring control over a product to a customer. Control transfer typically occurs when goods are shipped from our facilities or at other predetermined control transfer points (for instance, destination terms). Shipping and handling costs related to contracts with customers for the sale of goods are accounted for as a fulfillment activity and are included in the cost of revenues. Accordingly, amounts billed to customers for such costs are included as a component of revenues. Contract liabilities relate to advance payments from customers for goods and services the Company has yet to provide. These customer prepayments totaled $2,504,687 and $10,524,222 as of June 30, 2025 and December 31, 2024, respectively. Of the $10,524,222 balance as of December 31, 2024, the Company recognized $3,839,185 and $8,397,313 as revenues for the three and six months ended June 30, 2025, respectively. Of the $737,503 customer prepayments as of December 31, 2023, the Company recognized $133,935 and $486,290 of contract liabilities as revenues during the three and six months ended June 30, 2024, respectively.
