              RESPONSE TO COMMENT LETTER DATED JUNE 13, 2006

Ladies and Gentlemen:

       This letter is written in response to the letter dated June 13, 2006 from
Mr. John Hartz, commenting on the Form 10-K of Spartech Corporation ("Company")
for the fiscal year ended October 29, 2005 and on the Company's Form 10-Q for
the quarter ended January 28, 2006.

       The Company's responses follow, set forth under the corresponding comment
headings from Mr. Hartz's letter. However, please be advised that the Company's
Form 10-Q for the second quarter of fiscal 2006 was filed on June 8, 2006, prior
to our receipt of Mr. Hartz's letter. Therefore, for purposes of our responses
below, "future filings" refers to filings subsequent to the Company's Form 10-Q
for the second quarter of fiscal 2006.

SIGNIFICANT ACCOUNTING POLICIES, ESTIMATES AND JUDGMENTS
REVENUE RECOGNITION, PAGE 24

   1.  WE NOTE THAT YOU MANUFACTURE PRODUCTS TO CUSTOM SPECIFICATIONS AGREED
       UPON WITH THE CUSTOMER IN ADVANCE. PLEASE CLARIFY FOR US IF YOU RECOGNIZE
       REVENUE UPON CUSTOMER ACCEPTANCE OR UPON SHIPMENT. IF YOU RECOGNIZE
       REVENUE UPON SHIPMENT, PLEASE DEMONSTRATE FOR US YOUR COMPLIANCE WITH THE
       CURRENT ACCOUNTING GUIDANCE SET FORTH IN SAB 101 AND 104.

       On page 24 of our MD&A and page 37 of our Notes to Consolidated
Financial Statements we indicate that: "we recognize revenue as product is
shipped." Although we produce many of our products to custom specifications, we
recognize revenue upon shipment in accordance with the following points
consistent with the guidance of the SAB's:

       a.  Standard shipping terms are FOB shipping point -- At the point of
           shipment, title and the risk and rewards of ownership pass to the
           customer.




SPARTECH CORPORATION

       b.  Customer acceptance provisions -- Although contracts do not include
           formal customer acceptance provisions, the warranty provisions of our
           contracts typically give customers the right to return the product,
           or to receive a replacement or refund at our option, if it fails to
           meet specifications. However, these specifications are objectively
           measured and tested prior to delivery as noted below at (c) and (d).

       c.  Product is inspected and tested prior to shipment -- Each of our
           facilities inspects and performs appropriate testing on the product
           to ensure compliance with specifications before shipment occurs.

       d.  Custom specifications can be objectively measured -- The
           specifications of our product are based on objective criteria such as
           thickness, melting point, and melt flow index. These are objective
           measurements that would not differ between our testing procedures and
           a customer's test of the product, if they choose to perform tests of
           the product's specifications.

       e.  Historical customer returns are analyzed, and we estimate and provide
           for future returns -- Most customer returns result from a customer
           being dissatisfied with the product, even though the product met the
           agreed-upon specifications. Sales returns for fiscal year 2005
           represented 1.1% of net sales. We estimate and provide for future
           returns consistent with the guidance of SFAS 48.

VALUATION OF LONG-LIVED ASSETS, PAGE 25

   2.  WE NOTE YOUR DISCLOSURE OF YOUR CURRENT POLICY REGARDING THE VALUATION OF
       LONG-LIVED ASSETS. BECAUSE GOODWILL REPRESENTS APPROXIMATELY 33% OF YOUR
       TOTAL ASSETS, WE BELIEVE THAT YOU SHOULD PROVIDE MORE DETAILED
       DISCLOSURES OF THE ASSUMPTIONS YOU USE WHEN ANALYZING GOODWILL FOR
       IMPAIRMENT. PLEASE PROVIDE US WITH REVISED DISCLOSURES FOR USE IN FUTURE
       FILINGS.

       In future filings, we will provide more detailed disclosures of the
assumptions we use when analyzing goodwill for impairment. Our revised proposed
disclosures are attached to this letter as Attachment A.

STATEMENT OF OPERATIONS, PAGE 31

   3.  WE NOTE YOU DISCLOSED IN MD&A ON PAGE 19 OF YOUR FILING THAT YOU PROVIDE
       TOLLING SERVICES. IF APPLICABLE, IN FUTURE FILINGS, SEPARATELY DISCLOSE
       TOLLING SERVICE REVENUES AND RELATED COSTS OF SERVICES IN THE STATEMENTS
       OF OPERATIONS AS REQUIRED BY RULES 5-03(b)(1) AND (2) OF REGULATION S-X.

       In the past, revenue from tolling has represented well under the 10%
threshold established for disclosure as a separate line item (total revenue from
tolling arrangements in FY 2005 was approximately 1.5%). We have disclosed the
level of tolling sales volume (in pounds sold) to provide additional insights
into the mix of our volume growth statistics. If in future periods, the total
revenues from these arrangements aggregate more than 10%, we will separately
disclose

tolling revenues and related costs of services in the statement of operations as
required by Rules 5-03(b)(1) and (2) of Regulation S-X.

NOTE 3 -- RESTRUCTURING, PAGE 38

   4.  IN FUTURE FILINGS, PLEASE PROVIDE A RECONCILIATION OF THE BEGINNING AND
       ENDING LIABILITY BALANCES, RELATING TO YOUR EXIT AND DISPOSAL ACTIVITIES,
       SHOWING SEPARATELY THE CHANGES DURING THE PERIOD ATTRIBUTABLE TO COSTS
       INCURRED AND CHARGED TO EXPENSE, COSTS PAID AND OTHERWISE SETTLED, AND
       ANY ADJUSTMENTS TO THE LIABILITY WITH AN EXPLANATION OF THE REASON
       THEREFORE, AS REQUIRED BY PARAGRAPH 20.B.(2) OF SFAS 146.

       In future filings we will provide a reconciliation of the beginning and
ending liability balances relating to our exit and disposal activities, showing
separately the changes during the period attributable to costs incurred and
charged to expense, costs paid and otherwise settled, and any adjustments to the
liability with an explanation of the reason thereof, as required by paragraph
20.b.(2) of SFAS 146.

NOTE 5 -- FIXED ASSET CHARGE, PAGE 40

   5.  WE NOTE THAT YOU RECORDED A CHARGE IN THE SECOND QUARTER OF FY 2005
       RELATED TO NON-EXISTING EQUIPMENT. DUE TO THE NUMBER OF TRANSACTIONS,
       PASSAGE OF TIME SINCE MANY OF THEM OCCURRED, AND THE WEAKNESSES IN
       DOCUMENTATION AND CONTROLS OVER THESE ACTIVITIES, YOU COULD NOT
       SPECIFICALLY IDENTIFY OR ALLOCATE THESE ASSET WRITE OFFS TO DISTINCT
       FISCAL YEARS WITH ANY CERTAINTY. WE PRESUME THIS MEANS THAT IT WAS
       EVIDENT THAT THE ASSETS MAY NOT HAVE EXISTED IN REPORTING PERIODS PRIOR
       TO THE SECOND QUARTER OF FY 2005. THE AMOUNT OF THE WRITE OFF WAS 39% OF
       PRE-TAX INCOME. AS NOTED THE MAGNITUDE OF THE IMPACT ON EARLIER PERIODS
       IS UNKNOWN.

       APB 20 REQUIRES THAT ERRORS IN FINANCIAL STATEMENTS BE CORRECTED THROUGH
       THE RETROACTIVE ADJUSTMENT OF PRIOR PERIODS. CONSIDERING THIS
       REQUIREMENT, IT IS UNCLEAR TO US HOW YOU AND YOUR AUDITORS CAME TO THE
       CONCLUSION THAT THE FY 2005 (AND EARLIER PERIOD) FINANCIAL STATEMENTS ARE
       FAIRLY PRESENTED IN ACCORDANCE WITH U.S. GAAP.

       After completing a physical count and reconciliation process, we
analyzed the available data and completed our best efforts to determine when the
errors occurred. We were able to determine that the impact did not materially
affect any one prior fiscal period given the timing of specific events such as
acquisitions, plant consolidations and closures, and machinery and equipment
transfers. Further, we were able to determine that the most recent prior fiscal
years (2003 and 2004) were less impacted because a significant portion of the
errors could be attributed to fiscal 2002 and prior. However, the exact impact
for each fiscal year could not be definitively measured and therefore,
adjustment amounts for each prior year as would be prescribed under APB 20 could
not be definitively supported. We considered correcting the errors through an
adjustment to beginning retained earnings for the earliest year presented (i.e.,
2003 opening retained earnings). However, we concluded that correcting the
errors through a current year adjustment to income was more transparent and
easier for the users of the financial statements to understand. The charge is

prominently presented as a separate line on the income statement and described
fully in the footnotes and MD&A.

       The basis for our conclusion that there were no prior periods materially
misstated follows. In investigating the potential causes of the error, for some
assets, we did find support for attributing a retroactive adjustment to a
specific period. For many of the other assets that did not have specific support
for the timing of the prior period adjustment, we were able to identify specific
events or circumstances that provided a "bright-line" date on the latest timing,
such as the closure of a facility, after which it could be reasonably assumed
that the physical assets did not exist. Based on these investigations and
analyses, we developed a schedule that categorized many of the asset write offs
as being attributable to a particular year OR PRIOR (emphasis added). Although
the precise timing could not be determined because of the lack of clear data or
support, from this analysis we could attribute $6.2 million of the $8.8 million
to specific fiscal years, primarily 2002 and prior, based on the latest possible
date of the write off as summarized in the subsequent table.

       Two examples of bright-line events were: (i) vacating our Rome, Georgia
owned facility in late 2000 and (ii) terminating a lease for our Oxnard,
California plant facility in 2001. In 2000, we moved the manufacturing of
various products to other existing operating facilities (Warsaw, Indiana;
Atlanta, Georgia; and Greenville, Ohio), stopped production for some customers,
closed our Rome operation, and subsequently sold the facility. There was $1.1
million of machinery and equipment from the Rome facility that did not get
transferred with the production to other plants and was not located in the 2005
physical inventory. We believe the assets were scrapped and disposed of between
the date we stopped production (September 2000) and the date we sold the
facility (March 2002), and should have been considered inactive and written off
at least by the end of fiscal year 2000. Therefore, the write off of these
assets was included in the $2,097K amount attributed to fiscal year 2000 as the
latest year potentially affected. In 2001, there were $1.4 million in assets
related to the leased facility in Oxnard that were not transferred to another
facility and were no longer used for production after 2001. In both cases, the
fixed assets for these locations continued to be recorded on a general ledger of
a region that included these and other locations. The errors occurred due to
inadequate controls and communication between our operating and accounting
personnel and between accounting centers which resulted in these assets
remaining in the general ledger despite the fact that the assets were physically
disposed of or abandoned.

       Other events of this sort and other supporting data enable us to
attribute $6.2 million of the write offs to the latest fiscal year to which we
believe the adjustment could relate. Further, if the amounts in the subsequent
table were combined with the entire $2.6 million for which timing is uncertain
to a specific fiscal year, no prior fiscal year would be considered materially
misstated -- particularly the prior fiscal years (2004 and 2003) presented in
the fiscal 2005 financial statements.

  LATEST YEAR AFFECTED (BY FISCAL YEAR)                                                     (IN THOUSANDS)

       This analysis assisted us in assessing the materiality of the write offs
to our prior fiscal years, but was not of conclusive evidence that we believed
could be used to definitively support recording the specific write offs to the
respective prior period financial statements. We believe this analysis supported
our conclusion that the amount that would represent a retroactive adjustment to
any prior year income statement presented was not material to that period.
Accordingly, we concluded that the entire $8.8 million write off should be
reflected in the fiscal 2005 results, the year of the physical observation. As
previously noted, we considered correcting the errors through retained earnings
but concluded that correcting the errors in the current fiscal year was more
transparent and easier for the users of the financial statements to understand.
The charge is prominently presented as a separate line on the income statement
and described fully in the footnotes and MD&A. In addition, we have fully
disclosed the fact that there was a material weakness in internal controls over
the existence of fixed assets that contributed to these errors that was
subsequently remediated prior to our implementation of the Sarbanes Oxley
Section 404 reporting requirements in October 2005. We understand that our
auditors concur with our conclusions regarding the accounting treatment and
disclosures for these fixed asset write offs.


       DURING THE COUNT PROCESS, YOU ALSO IDENTIFIED EQUIPMENT THAT EXISTS AND
       THAT YOU DECIDED TO LIQUIDATE. PLEASE EXPLAIN TO US WHETHER THOSE
       LIQUIDATIONS MAY HAVE REPRESENTED OBSOLETE, OR INACTIVE ASSETS, PRIOR TO
       THE TIME THEY WERE LIQUIDATED AND SHOULD HAVE BEEN CONSIDERED
       UNREALIZABLE AT ANY EARLIER PERIOD.

       During our physical inventory process which was completed in May 2005, we
provided specific written instructions and followed up with guidance on specific
facts and circumstances, not just regarding the identification of non-existent
assets, but also for identifying underutilized assets that should be considered
for sale or abandonment. As a result, we identified assets that were used
sparingly or as back-up equipment and certain equipment that was inefficient. We
did not identify assets that were completely inactive and that should have been
impaired prior to that date. Prior to our strategic assessment, the assets were
appropriately grouped with other operating assets as "held and used" and were
being depreciated over their estimated useful life. However, upon identifying
the underutilized equipment, we challenged our operating personnel to evaluate
where we could replace inefficient equipment or monetize certain equipment for
alternative intermittent use or back-up solutions. The impairment charge of $1.9
million recognized in fiscal 2005 related to those assets reflected current year
operational decisions to sell or abandon assets made upon evaluating the future
use of these assets in our second, third, and fourth quarters of 2005.

       ALSO, WE NOTE THAT IN THE SECOND QUARTER OF FY 2005, YOU INCLUDED THE
       FOLLOWING DISCLOSURES IN YOUR FORM 10-Q, "IN THE OPINION OF MANAGEMENT,
       THE FINANCIAL STATEMENTS CONTAIN ALL ADJUSTMENTS (CONSISTING SOLELY OF
       NORMAL RECURRING ADJUSTMENTS) AND DISCLOSURES NECESSARY TO MAKE THE
       INFORMATION PRESENTED THEREIN NOT MISLEADING." HELP US BETTER UNDERSTAND
       HOW THE FIXED ASSET WRITE OFF WAS CONSIDERED TO BE A NORMAL RECURRING
       ADJUSTMENT.

       The parenthetical disclosure noted above was an oversight. We should have
revised this language to identify the adjustments in this quarter as both normal
recurring adjustments and adjustments to properly correct the fixed assets for
non-existing equipment and to reflect the impairment charge on certain assets.
We will be more careful in future filings to consider all facts and
circumstances in making this disclosure.

NOTE 17 -- SEGMENT INFORMATION, PAGE 50

   6.  WE NOTE THAT YOU HAVE THREE REPORTABLE SEGMENTS: CUSTOM SHEET AND
       ROLLSTOCK, COLOR AND SPECIALTY COMPOUNDS, AND ENGINEERED PRODUCTS. IT
       APPEARS FROM YOUR DISCLOSURES ELSEWHERE IN THE FILING, INCLUDING THE
       INDUSTRY OVERVIEW ON PAGE TWO, YOUR DISCUSSION OF OPERATING SEGMENTS ON
       PAGE FOUR, AND THE ANALYSIS OF YOUR BUSINESS IN MD&A, THAT YOU MAY HAVE
       AGGREGATED MULTIPLE OPERATING SEGMENTS INTO YOUR REPORTABLE SEGMENTS.
       PLEASE PROVIDE US WITH A DETAILED EXPLANATION OF HOW YOUR DETERMINED BOTH
       YOUR OPERATING SEGMENTS AND YOUR REPORTABLE SEGMENTS. YOUR RESPONSE
       SHOULD SPECIFICALLY IDENTIFY EACH OF YOUR OPERATING SEGMENTS. IF YOU HAVE
       AGGREGATED ANY OPERATING SEGMENTS, PLEASE TELL US WHY YOU BELIEVE THIS
       AGGREGATION IS APPROPRIATE BASED ON THE GUIDANCE FOUND IN PARAGRAPH 17 OF
       SFAS 131 AND EITF 04-10.



   As indicated on page 4 of our 2005 Form 10-K, we operated 43 production
facilities in three operating segments; (1) Custom Sheet and Rollstock, (2)
Color and Specialty Compounds, and (3) Engineered Products. Each of these
segments engages in business activities from which it earns revenues and incurs
expenses, has operating results that are regularly reviewed by our chief
operating decision maker to make decisions about resource allocation and assess
performance, and has discrete financial information. Our disclosure of certain
names in the Industry Overview and MD&A sections of our Form 10-K (e.g.,
Spartech Plastics, Spartech Polycast, Spartech Polycom, etc.) includes names of
specific plants or plant groupings, the names of which we carried forward from a
previous acquisition, or names that we use for marketing purposes. Our basis for
determining our operating segments reflects the way management has organized the
Company for making decisions and assessing performance.

   Each of the three segments has a "segment manager" located at our corporate
office who is directly accountable and maintains regular contact with our Chief
Executive Officer ("chief operating decision maker") to discuss operating
activities, financial results, performance to budget, and the status of
strategic investments and plans. Our segment managers are held responsible for
the results of our operating segments on the whole versus any individual
components of the operating segments. In addition, we communicate our monthly
results to our Board of Directors for the three operating segments and do not
communicate results of components within operating segments. Supplemental
information is also available for detailed components for purposes of

explaining variances within our operating segment results; however, resources
are allocated at the operating segment level and the level of information
predominately communicated and analyzed by management for these purposes occurs
at our operating segment level. Finally, the nature of our business activities
is similar for each component within our operating segments and is different
when comparing components of one operating segment to another. The following
describes the commonality of the overall nature of business activities for the
components of each of our three operating segments:

Custom Sheet and Rollstock

     -    Base production process is the conversion of oil and natural gas-based
          raw material into plastic sheet and rollstock.

     -    Plastic sheet and rollstock is sold to original equipment manufactures
          to be formed into an end product which is sold to the end consumer.

     -    Finished product is one manufacturing step away from the end consumer.

Color and Specialty Compounds

     -    Base production process is the chemical and physical manipulation of
          oil and natural gas-based color concentrates and plastic compounds
          into resins and films.

     -    Resins and films are sold to customers who injection mold, extrude,
          blow mold or cast film our products before they can be used in an end
          product and include the sale of products to our Custom Sheet and
          Rollstock and Engineered Products segments.

     -    Finished product is two manufacturing steps away from the end
          consumer.

Engineered Products

     -    Base production process is the conversion of oil and natural gas-based
          plastic resins into end products.

     -    End products are either sold to the end consumer in its finished state
          or assembled by our customers into an end product without further
          manufacturing processing.

     -    Finished product is sold as is to the end customer.

We have not aggregated any operating segments into a reportable segment.

COMMENT 2:  VALUATION OF LONG-LIVED ASSETS, PAGE 25

The following revised disclosure will be used in future filings:

         VALUATION OF GOODWILL -- We conduct a formal impairment test of
goodwill on an annual basis on the first day of the Company's fiscal fourth
quarter and prior to the next annual testing date if an event occurs or
circumstances change that would make it more likely than not that the fair value
of a reporting unit is below its carrying amount. The goodwill impairment test
is a two-step process which requires us to make judgmental assumptions regarding
fair value. The first step consists of estimating the fair value of each
reporting unit using a number of judgmental factors including projected future
operating results and business plans, economic projections, anticipated future
cash flows, discount rates and comparable marketplace fair value data from
within a comparable industry grouping. We compare the estimated fair values of
each reporting unit to the respective carrying values which includes allocated
goodwill. If the estimated fair value is less than the carrying value, the
second step is completed to compute the impairment amount by determining the
"implied fair value" of goodwill. This determination requires the allocation of
the estimated fair value of the reporting unit to the assets and liabilities of
the reporting unit. Any remaining unallocated fair value represents the "implied
fair value" of goodwill which is compared to the corresponding carrying value to
compute the goodwill impairment amount. We believe our estimates of the
underlying components of fair value are reasonable. However, should actual
results not meet our expectations or assumptions change in future years, our
impairment assessment could result in a lower fair value estimates which could
result in an impairment charge that may materially affect the carrying value of
our assets and results from operations.
