Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND PRINCIPAL ACTIVITIES	NOTE 1 - ORGANIZATION AND PRINCIPAL ACTIVITIES The accompanying unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted as permitted by rules and regulations of the Securities and Exchange Commission ("SEC"). The consolidated balance sheet as of December 31, 2018 was derived from the audited consolidated financial statements of Yew Bio-Pharm Group, Inc. (individually "YBP" and collectively with its subsidiaries and operating variable interest entity, the "Company"). The accompanying unaudited interim consolidated financial statements should be read in conjunction with the summary of significant accounting policies and notes to consolidated financial statements included in the Company's annual report on Form 10-K for the year ended December 31, 2018. In the opinion of management, all adjustments (which include normal recurring adjustments) necessary to present a fair statement of the financial position as of March 31, 2019, and the results of operations and cash flows for the three-month periods ended March 31, 2019 and 2018, have been presented. The preparation of consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company continually evaluates its estimates, including those related to bad debts, inventories, income taxes, and the valuation of equity transactions. The Company bases its estimates on historical experience and on various other assumptions that it believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Any future changes to these estimates and assumptions could cause a material change to our reported amounts of revenues, expenses, assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. Certain amounts from prior period financial statements have been reclassified to conform to the current period presentation. This reclassification has resulted in no changes to the Company's financial position or results of operations presented. Details of the Company's subsidiaries, variable interest entity ("VIE") and VIE's subsidiary are as follows: Name Domicile and Date of Incorporation Registered Capital Effective Ownership Principal Activities Heilongjiang Jinshangjing Bio-Technology Development Co., Limited ("JSJ") PRC October 29, 2009 US$100,000 100% Holding company Yew Bio-Pharm Holdings Limited ("Yew Bio-Pharm (HK)") Hong Kong November 29, 2010 HK$10,000 100% Holding company of JSJ Harbin Yew Science and Technology Development Co., Ltd.

Principles of Consolidation [Abstract]
PRINCIPLES OF CONSOLIDATION	NOTE 2 - PRINCIPLES OF CONSOLIDATION The consolidated financial statements include the financial statements of YBP, its subsidiaries and operating VIE and its subsidiary in which the Company is the primary beneficiary. All significant intercompany balances and transactions have been eliminated on consolidation. Pursuant to a restructuring plan intended to ensure compliance with applicable PRC laws and regulations (the "Second Restructure"), on November 5, 2010, JSJ entered into a series of contractual arrangements (the "Contractual Arrangements") with HDS and/or Zhiguo Wang, his wife Guifang Qi and Xingming Han (collectively with Mr. Wang and Madame Qi, the "HDS Shareholders"), as described below: ● Exclusive Business Cooperation Agreement ● Exclusive Option Agreement ● Equity Interest Pledge Agreement ● Power of Attorney . To the extent that the Contractual Arrangements are enforceable under PRC law, as from time to time interpreted by relevant state agencies, they constitute the valid and binding obligations of each of the parties to each such agreement. The Company believes that HDS is considered a VIE under ASC 810 "Consolidation", because the equity investors in HDS no longer have the characteristics of a controlling financial interest, and the Company, through JSJ, is the primary beneficiary of HDS and controls HDS's operations. Accordingly, HDS has been consolidated as a deemed subsidiary into YBP as a reporting company under ASC 810. YBP has no direct or indirect legal or equity ownership interest in HDS. However, through the Contractual Arrangements, the stockholders of HDS have assigned all their rights as stockholders, including voting rights and disposition rights of their equity interests in HDS to JSJ, our indirect, wholly-owned subsidiary. YBP is deemed to be the primary beneficiary of HDS and the financial statements of HDS are consolidated in the Company's consolidated financial statements. At March 31, 2019 and December 31, 2018, the carrying amount and classification of the assets and liabilities in the Company's balance sheets that relate to the Company's variable interest in the VIE and VIE's subsidiary are as follows: March 31, 2019 December 31, 2018 Assets Cash $ 213,413 $ 478,293 Accounts receivable - related parties, net of allowance for doubtful account $1,178,526 and $837,929 8,297,428 4,579,666 Inventories (current and long-term), net 6,687,361 6,567,144 Prepaid expenses and other assets 49,902 34,492 Advance to suppliers 159,393 - Advance to suppliers - related parties 1,517,903 - Prepaid expenses - related parties 25,759 32,318 Property and equipment, net 504,848 506,949 Long-term investment in MC 2,898,475 2,449,757 Land use rights and yew forest assets, net 33,125,420 34,914,793 Operating lease right of use 270,848 VAT recoverables 1,007,232 985,831 Total assets of VIE and its subsidiary $ 54,757,982 $ 50,549,243 Liabilities Accrued expenses and other payables $ 366,959 $ 237,114 Accounts payable 43,929 10,410 Advance from customer 149 145 Advance from customer-related party 2,371,697 21,295 Taxes payable 21,720 - Short-term borrowings 5,520,137 5,758,517 Operating lease liability- current 10,483 - Operating lease liability- noncurrent 254,348 - Deferred income 348,676 340,294 Due to related parties and VIE holding companies 675,166 658,501 Total liabilities of VIE and its subsidiary $ 9,613,264 $ 7,026,276 Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board ("FASB") issued new leasing guidance ("Topic 842") that replaced the existing lease guidance ("Topic 840"). Topic 842 established a right-of-use ("ROU") model that requires a lessee to record a ROU asset and lease liability on the balance sheet for all leases with terms longer than 12 months. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the statement of operations. This guidance also expanded the requirements for lessees to record leases embedded in other arrangements and the required quantitative and qualitative disclosures surrounding leases. The Company adopted Topic 842 on its effective date of January 1, 2019 using a modified retrospective transition approach; as such, Topic 842 will not be applied to periods prior to adoption and the adoption had no impact on the Company's previously reported results. The Company elected the package of practical expedients permitted under the transition guidance within Topic 842, which allowed the Company to carry forward its identification of contracts that are or contain leases, its historical lease classification and its accounting for initial direct costs for existing leases. The impact of adopting Topic 842 was not material to the Company's result of operations or cash flows for the three months ended March 31, 2019. The Company recognized operating lease liabilities of $373,517 upon adoption, with corresponding ROU assets on its balance sheet. Recently Issued Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU No. 2016-13, (Topic 326), Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments which amends the current accounting guidance and requires the use of the new forward-looking "expected loss" model, rather than the "incurred loss" model, which requires all expected losses to be determined based on historical experience, current conditions and reasonable and supportable forecasts. This guidance amends the accounting for credit losses for most financial assets and certain other instruments including trade and other receivables, held-to-maturity debt securities, loans and other instruments. ASU 2016-13 is effective for public entities for annual periods beginning after December 15, 2019, and interim periods within those annual periods. Early adoption is permitted for annual periods beginning after December 15, 2018, and interim periods therein. The Company is evaluating the impact of the adoption of ASU 2016-13 on its financial position and results of operations.

Revenue Recognition

Notes to Financial Statements
REVENUE RECOGNITION	NOTE 3 - REVENUE RECOGNITION The Company accounts for revenue arising from contracts and customers in accordance with Accounting Standards Update (ASU or Update) No. 2014-09, Revenue from Contracts with Customers ("ASC 606") Under ASC 606, the Company recognizes revenue when its customer obtains control of promised goods, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods. To determine revenue recognition for arrangements that the Company determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that Company will collect the consideration it is entitled to in exchange for the goods it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods promised within each contract and determines those that are performance obligations and assesses whether each promised good is distinct. The Company then recognizes as revenue the amount of the transaction price, which is allocated to the respective performance obligation, when the performance obligation is satisfied. Generally, the Company's performance obligations are satisfied when the customers take possession of the products, which normally occurs upon shipment or delivery depending on the terms of the contracts. In general, the Company's products within its segments are aligned according to the nature and economic characteristics of its products and provide meaningful disaggregation of each business segment's results of operations. Disaggregation of revenue by business segment are included in Note 12 - SEGMENT INFORMATION.

TAXES	NOTE 5 - TAXES (a) Federal Income Tax and Enterprise Income Taxes The table below summarizes the difference between the U.S. statutory federal tax rate and the Company's effective tax rate for the three months ended March 31, 2019 and 2018: Three Months Ended March 31, 2019 2018 U.S. federal income tax rate 21.00 % 21.00 % Tax rate difference 5.62 % 2.10 % Loss not subject income tax 8.71 % - Foreign income not recognized in the U.S. - (21.00 )% PRC EIT rate - 25.00 % PRC tax exemption and reduction (40.75 )% (28.00 )% Valuation allowance - 0.90 % Effective tax rate (5.42 )% - The U.S. Tax Cuts and Jobs Act (the "Tax Act") was enacted on December 22, 2017. The Tax Act among other changes, reduces the U.S. federal corporate tax rate from 35% to 21%, eliminating certain deductions, imposing a mandatory one-time tax on accumulated earnings of foreign subsidiaries, introducing new tax regimes, and changing how foreign earnings are subject to U.S. tax. The Company has determined the implication of the tax rate reduction does not have any impact on the consolidated financial statements. One-time transition tax is based on the Company's total post-1986 earnings and profits ("E&P") that it previously deferred from U.S. income taxes. The Company completed its calculation and recorded $1,431,835 of the transition tax on undistributed earnings of non-U.S. subsidiaries during the year ended December 31, 2018. As of March 31, 2019 and December 31, 2018, the Company had current income tax payable of $Nil and $114,547 and noncurrent income tax payable of $1,202,741 and $1,202,741.
