- NATURE OF BUSINESS
 
ADM Tronics Unlimited, Inc. ("we", "us", the “Company" or "ADM"), was incorporated under the laws of the state of Delaware on
November 24, 1969.
 We are a technology-based developer and manufacturer of diversified lines of products and derive revenues from the production and sale of electronics for medical devices and other applications; environmentally safe chemical products for industrial, medical and cosmetic uses; and, research, development, regulatory and engineering services.
 
The accompanying unaudited condensed consolidated financial statements have been prepared by ADM pursuant to generally accepted accounting principles in the United States and
 the rules and regulations of the Securities and Exchange Commission (“SEC”) including Form
10
-Q and Regulation S-
X.
The information furnished herein reflects all adjustments (consisting of normal recurring accruals and adjustments) which are, in the opinion of management, necessary to fairly present the condensed financial position and operating results for the respective periods. Certain information and footnote disclosures normally present in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and explanatory notes for the year ended
March 31, 2017
as disclosed in our annual report on Form
10
-K for that year. The operating results and cash flows for

PRINCIPLES OF CONSOLIDATION
 
The condensed consolidated financial statements include the accounts of ADM Tronics Unlimited, Inc. and its wholly owned subsidiary Sonotron. All significant intercompany balances and transactions have been eliminated in consolidation.
 
USE OF ESTIMATES
 
These unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America
 and, accordingly, require management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. Significant estimates made by management include expected economic life and value of our medical devices, reserves, deferred tax assets, valuation allowance, impairment of long lived assets, fair value of equity instruments issued to consultants for services and fair value of equity instruments issued to others, option and warrant expenses related to compensation to employees and directors, consultants and investment banks, allowance for doubtful accounts, and warranty reserves. Actual results could differ from those estimates.  
 
REVENUE RECOGNITION
 
CHEMICAL PRODUCTS:
 
Revenues are recognized when products are shipped to end users. Shipments to distributors are recognized as revenue when
no
right of return exists.
 
 
ELECTRONICS:
 
 
We recognize revenue from the sale of our electronic products when they are shipped to the purchaser. We offer a limited
90
-day warranty on our electronics products and a limited
5
-year warranty on our electronic controllers for spas and hot tubs. We have
no
other post shipment obligations. Based on prior experience,
no
amounts have been accrued for potential warranty costs and actual costs were less than
$2,000
,
for each of the
three
and
six
months ended
September 30, 2017
and
2016.
For contract manufacturing, revenues are recognized after shipment of the completed products. 
 
ENGINEERING SERVICES:
 
 
We provide certain engineering services, including research, development, quality control, and quality assurance services along with regulatory compliance services. We recognize revenue from engineering services as the services are provided.
 
 
EARNINGS
 PER SHARE
 
Basic
 earnings per share is calculated based on the weighted average number of common shares outstanding during the periods. Diluted earnings per share is computed similar to basic earnings per share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential shares had been issued and if the additional shares were dilutive.
 
 
Per share basic and diluted
 earnings amounted to
$0.00
and
$0.01
for the
three
and
six
months ended
September 30, 2017
and
2016,
respectively. There were
3,000,000
common stock equivalents at
September 30, 2017
and
2016,
respectively.
 
RECLASSIFICATION
 
Certain items in the prior
period condensed consolidated financial statements have been reclassified to conform to the current period presentation.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
Management is still evaluating the impact of recently issued, but
not
yet effective accounting pronouncements, if adopted. The effects of the standards on the Company
’s consolidated financial statements are
not
known at this time.

 - INCOME TAXES
 
At
September 30, 2017,
the Company had federal net operating loss carry-forwards ("NOL")'s of approximately
$1,902,000,
which are due to expire through fiscal
2034.
 
These NOLs
may
be used to offset future taxable income through their respective expiration dates and thereby reduce or eliminate our federal income taxes otherwise payable. A valuation allowance is provided when it is more likely than
not
that some portion or all of the deferred tax assets will
not
be realized. Ultimate utilization of such NOL's and credits is dependent upon the Company's ability to generate taxable income in future periods and
may
be significantly curtailed if a significant change in
 
ownership occurs.
 
 
The Company provides a
 partial valuation allowance for the deferred tax asset resulting from the uncertainty that the stock-based compensation will be deductible. During the
six
months ended
September 30, 2017,
the Company utilized approximately
$386,000
in net operating losses and expects to utilize the entire
$1,902,000
before expiration.
 
The effective rates were approximately
41%
and
(
6%
)
for the
three
and
six
months ended
September 30, 2017
and
2016,
respectively. The
2016
tax rates were favorably impacted relative to the statutory rate by a decrease in the valuation allowance related to the estimated net operating loss carry-forward utilization.

Accounting Policies [Abstract]  
Consolidation, Policy [Policy Text Block]
PRINCIPLES OF CONSOLIDATION
 
The condensed consolidated financial statements include the accounts of ADM Tronics Unlimited, Inc. and its wholly owned subsidiary Sonotron. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates, Policy [Policy Text Block]
USE OF ESTIMATES
 
These unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America
 and, accordingly, require management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. Significant estimates made by management include expected economic life and value of our medical devices, reserves, deferred tax assets, valuation allowance, impairment of long lived assets, fair value of equity instruments issued to consultants for services and fair value of equity instruments issued to others, option and warrant expenses related to compensation to employees and directors, consultants and investment banks, allowance for doubtful accounts, and warranty reserves. Actual results could differ from those estimates.  
Revenue Recognition, Policy [Policy Text Block]
REVENUE RECOGNITION
 
CHEMICAL PRODUCTS:
 
Revenues are recognized when products are shipped to end users. Shipments to distributors are recognized as revenue when
no
right of return exists.
 
 
ELECTRONICS:
 
 
We recognize revenue from the sale of our electronic products when they are shipped to the purchaser. We offer a limited
90
-day warranty on our electronics products and a limited
5
-year warranty on our electronic controllers for spas and hot tubs. We have
no
other post shipment obligations. Based on prior experience,
no
amounts have been accrued for potential warranty costs and actual costs were less than
$2,000
,
for each of the
three
and
six
months ended
September 30, 2017
and
2016.
For contract manufacturing, revenues are recognized after shipment of the completed products. 
 
ENGINEERING SERVICES:
 
 
We provide certain engineering services, including research, development, quality control, and quality assurance services along with regulatory compliance services. We recognize revenue from engineering services as the services are provided.
 
Earnings Per Share, Policy [Policy Text Block]
EARNINGS
 PER SHARE
 
Basic
 earnings per share is calculated based on the weighted average number of common shares outstanding during the periods. Diluted earnings per share is computed similar to basic earnings per share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential shares had been issued and if the additional shares were dilutive.
 
 
Per share basic and diluted
 earnings amounted to
$0.00
and
$0.01
for the
three
and
six
months ended
September 30, 2017
and
2016,
respectively. There were
3,000,000
common stock equivalents at
September 30, 2017
and
2016,
respectively.
Reclassification, Policy [Policy Text Block]
RECLASSIFICATION
 
Certain items in the prior
period condensed consolidated financial statements have been reclassified to conform to the current period presentation.
New Accounting Pronouncements, Policy [Policy Text Block]
RECENT ACCOUNTING PRONOUNCEMENTS
 
Management is still evaluating the impact of recently issued, but
not
yet effective accounting pronouncements, if adopted. The effects of the standards on the Company
’s consolidated financial statements are
not
known at this time.
