1.01 Conflict Minerals Disclosure and Report</font></b></p>

<p style="margin:0cm;margin-bottom:12.0pt;text-align:justify;text-indent:18.0pt;text-justify:inter-ideograph;"><font face="times new roman" lang=EN-US style="font-size:10.0pt;">This
report for the year ended December 31, 2017 is presented to comply with Rule
13p-1 under the Securities Exchange Act of 1934, or the Rule. The Rule was
adopted by the Securities and Exchange Commission, or the SEC, to implement
reporting and disclosure requirements related to conflict minerals as directed
by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. The
Rule imposes certain reporting obligations on SEC registrants whose
manufactured products contain conflict minerals which are necessary to the
functionality or production of their products. Conflict minerals are defined as
cassiterite, columbite-tantalite, gold, wolframite, and their derivatives,
which are limited to tin, tantalum and tungsten for the purposes of this
assessment. These requirements apply to registrants whatever the geographic
origin of the conflict minerals and whether or not they fund armed conflict.</font></p>

<p style="margin:0cm;margin-bottom:12.0pt;text-align:justify;text-indent:18.0pt;text-justify:inter-ideograph;"><font face="times new roman" lang=EN-US style="font-size:10.0pt;">We,
Companhia Sider&#250;rgica Nacional, evaluated our current product lines and
determined that certain products we manufacture or contract to manufacture
contain tin, a derivative of cassiterite. We also determined that none of the
products we manufacture or contract to manufacture contains other conflict
minerals.</font></p>

<p style="margin:0cm;margin-bottom:12.0pt;text-align:justify;text-indent:18.0pt;text-justify:inter-ideograph;"><font face="times new roman" lang=EN-US style="font-size:10.0pt;">We
conducted in good faith a reasonable country of origin inquiry, or RCOI,
regarding conflict minerals and have determined that, during the period covered
by this specialized disclosure report, no conflict minerals originated in the
Democratic Republic of the Congo or adjoining countries nor came from recycled
or scrap sources.</font></p>

<p style="margin:0cm;margin-bottom:12.0pt;text-align:justify;text-indent:18.0pt;text-justify:inter-ideograph;"><font face="times new roman" lang=EN-US style="font-size:10.0pt;">Our
RCOI process included (i) the development and establishment of governance
structures across multiple departments, including procurement, quality
assurance, supply chain and legal, (ii) requiring all suppliers to provide a
certificate of origin for all conflict minerals we purchase, (iii)
record-keeping, and (iv) escalation and follow-up procedures to identify and
escalate any identified issues associated with non-responsive or problematic
responses to our RCOI.</font></p>

<p style="margin:0cm;margin-bottom:12.0pt;text-align:justify;text-indent:18.0pt;text-justify:inter-ideograph;"><font face="times new roman" lang=EN-US style="font-size:10.0pt;">In
addition, our RCOI process is aided by (i) the fact that cassiterite is
abundant in Brazil specifically and South America in general, (ii) our
knowledge of the industry, being ourselves the owners and operators of a
cassiterite mine and tin smelter in northern Brazil, through a wholly-owned
subsidiary; and (iii) the fact that we are a direct consumer of tin.</font></p>

<p style="margin:0cm;margin-bottom:12.0pt;text-align:justify;text-indent:18.0pt;text-justify:inter-ideograph;"><font face="times new roman" lang=EN-US style="font-size:10.0pt;">Based
on our RCOI process described above, we have determined that, during the period
covered by this specialized disclosure report, we purchased tin from four suppliers,
all of which are Brazilian integrated mining companies and smelters, who
extract their own cassiterite in Brazil (one of these suppliers is our
wholly-owned subsidiary ERSA, located in northern Brazil). The outside
suppliers have provided us certificates of origin confirming that the tin we
purchased was derived from cassiterite extracted in Brazil. We have also
determined through our due diligence and knowledge of the market that the price
and logistics for delivery of the tin we purchase is consistent with what we
would expect for cassiterite extracted in Brazil.</font></p>
