             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Participants and the Plan Administrative Committee of
the Harsco Corporation Savings Plan:


In our opinion, the accompanying statement of net assets available for benefits
and the related statement of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of the Harsco Corporation Savings Plan (the "Plan") at December 31, 2006 and
2005, and the changes in net assets available for benefits for the year ended
December 31, 2006 in conformity with accounting principles generally accepted in
the United States of America. These financial statements are the responsibility
of the Plan's management. Our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with the standards of the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule of assets held for
investment purpose is presented for the purpose of additional analysis and is
not a required part of the basic financial statements but is supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. This supplemental schedule is the responsibility of the Plan's management.
The supplemental schedule has been subjected to the auditing procedures applied
in the audits of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

                          NOTES TO FINANCIAL STATEMENTS
                          -----------------------------


1.     General Description of Plan:
       ----------------------------

       General
       -------

       The following description of the Harsco Corporation Savings Plan (the
       "Plan") provides only general information. Participants should refer to
       the Summary Plan Description for a more complete description of the
       Plan's provisions.

       The Plan is a defined contribution plan designed to comply with the
       requirements of the Employee Retirement Income Security Act of 1974
       ("ERISA") and with the requirements for qualification under Sections
       401(a) and 401(k) of the Internal Revenue Code (the "Code").

       As of January 1, 2005, all U.S. hourly and Air-X-Changers salaried
       employees who are employed by Harsco Corporation (the "Company") or any
       subsidiary of either the Company or a subsidiary which adopts this Plan
       with the approval of the Company shall be covered by, or remain covered
       by this Plan, are deemed "Eligible Employees." Also eligible are
       employees covered by a collective bargaining agreement where the
       agreement provides for the employees' eligibility to participate in the
       Plan. Prior to January 1, 2005, in addition to hourly employees, eligible
       employees also included all U.S. employees (including officers) who
       received a stated weekly, monthly, or annual rate of compensation. New
       employees deemed Eligible Employees under this Plan are eligible to
       participate in the Plan as of the first payroll of January, April, July
       or October after the date of hire.

       Throughout the year, employees are transferred to various positions
       within the Company, which may result in a transfer between various
       retirement plans. This is shown as "Net transfers to HRSIP," on the
       Statement of Changes in Net Assets Available for Benefits.

       Contributions
       -------------

       To participate in the Plan, an Eligible Employee must elect to contribute
       to the Plan through payroll deductions each pay period. Contributions are
       in whole percentages from 1% to 75% of compensation received for services
       as an employee of the Company or any subsidiary of the Company. The
       participant shall designate what percentage of such contributions will be
       "Pre-Tax Contributions" and what percentage will be "After-Tax
       Contributions." A participant who makes Matched Pre-Tax and/or Matched
       After-Tax Contributions in an aggregate amount of 6% of his or her
       compensation may also elect to contribute from 1% to 69% of his or her
       compensation as an Unmatched Pre-Tax Contribution and from 1% to 16% of
       his or her compensation as an Unmatched After-Tax Contribution, subject
       to IRS and Plan limitations. In no event during the year may (a) Matched
       Pre-Tax and Matched After-Tax Contributions exceed 6% of compensation,
       (b) Unmatched Pre-Tax and Unmatched After-Tax Contribution exceed 69% of
       compensation or (c) Pre-Tax Contributions exceed the amount specified by
       the Internal Revenue Service (IRS) code which was $15,000 and $14,000 for
       the years ended December 31, 2006 and 2005, respectively, for
       participants under 50 years of age. For participants who turned 50 on or
       before the end of the calendar year, the pretax limit was $20,000 and
       $18,000 in 2006 and 2005, respectively, as a result of an additional
       $5,000 and $4,000 of

1.     General Description of Plan: (continued)
       ----------------------------------------

       "catch-up contributions" allowed by law in 2006 and 2005, respectively.
       Pre-Tax Contributions shall constitute a reduction in the participant's
       taxable income for purposes of Section 401(k) of the Code. After-Tax
       Contributions will be considered to be the participant's contributions to
       the Plan and shall not constitute a reduction in the participant's
       taxable income for the purposes of Section 401(k) of the Code.
       Pursuant to the Plan, the Company will make contributions in cash to the
       trustee for the account of each participant in an amount equal to 50% of
       the first 6% of such participant's compensation designated as Matched
       Pre-Tax Contributions and/or Matched After-Tax Contributions. These
       contributions are referred to as "Company Matching Contributions".

       Vesting
       -------

       Participants are immediately vested in their contributions plus actual
       earnings thereon. Vesting in the Company's Matching Accounts is based on
       years of vesting service. A participant is 100% vested after three years
       of credited service.

       Administration
       --------------

       The Company pays administrative fees related to maintaining the Plan as a
       whole. Fees for investment management, which include recordkeeper fees,
       are subtracted from fund performance reported by each fund. Loan setup
       fees, quarterly loan fees and withdrawal fees are paid by the
       participant. Transfers in and out of the Harsco Corporation Common Stock
       Fund are assessed a $0.03 commission per share transferred.

       Participant Loans
       -----------------

       Participants may borrow from their fund accounts a minimum of $500 to a
       maximum of 50% of their vested account balance, not to exceed $50,000.
       Loan transactions are treated as a transfer to (from) the respective
       investment fund(s) from (to) the Participant Loans fund. The participant
       may choose the loan repayment period, not to exceed five years. However,
       the term may be for any period not to exceed 15 years if the purpose of
       the loan is to acquire the participant's principal residence. The loans
       are collateralized only by the portion of the participant's account from
       which the loan is made and bear interest at a rate commensurate with
       local prevailing rates as determined periodically by the Plan
       administrator. Interest rates on outstanding loans, based on the
       trustee's prime rate plus one percent, ranged from 4.25% to 10.5% at
       December 31, 2006. Principal and interest is paid ratably through payroll
       deductions.

       On termination of service, a participant or beneficiary may elect one of
       three options. The participant or beneficiary may elect to receive either
       a lump-sum amount equal to the value of the participant's vested interest
       in his or her account; a portion paid in a lump-sum, and the remainder
       paid later; or annual installments over not more than fifteen years.

            income as Putnam's management believes is consistent with
            preservation of capital and maintenance of liquidity. The fund
            consists of short-term high-quality money market securities.
            Investments in this fund are neither insured nor guaranteed by the
            U.S. government.

       (13) Putnam New Opportunities Fund - a fund consisting primarily of
            investments in common stock of U.S. companies within certain
            industry groups that Putnam management believes have high growth
            potential.

       (14) Putnam Voyager Fund - a fund consisting mainly of investments in
            stock of midsized to large companies expected to grow over time. The
            fund invests all or a portion of its assets in companies located
            mainly inside the United States.

       (15) Vanguard Institutional Index Fund - a fund consisting of investments
            in the same stocks and in substantially the same percentages as the
            S&P 500 Index.

       (16) Putnam Retirement Ready Funds (2010-2050) - a fund employing an
            asset allocation strategy based on investors' projected retirement
            year. The fund seeks capital appreciation and current income.

       (17) T. Rowe Price Retirement Funds (2005-2045) - a fund employing an
            asset allocation strategy based on investors' projected retirement
            year. The fund invests in a combination of T. Rowe Price mutual
            funds representing different types of stocks and bonds.

       The Plan provides for various investment options as described above.
       Investment securities are exposed to various risks, such as interest
       rate, market, and credit. Due to the level of risk associated with
       certain investment securities and the level of uncertainty related to
       changes in the value of investment securities, it is at least reasonably
       possible that changes in risks in the near term could materially affect
       participants' account balances and the amounts reported in the statement
       of net assets available for plan benefits and the statement of changes in
       net assets available for plan benefits.

1.     General Description of Plan: (continued)
       ----------------------------------------

       Plan Termination
       ----------------

       While the Company has not expressed any intent to discontinue the Plan,
       it reserves the right to terminate the Plan at any time or discontinue
       contributions thereunder. In the event such discontinuance resulted in
       the termination of the Plan, the accounts of each affected employee who
       has not yet incurred a break in service shall be fully vested. Complete
       distributions or withdrawals would be distributed to Plan participants
       and beneficiaries in proportion to their respective account balances.


2.     Summary of Significant Accounting Policies:
       -------------------------------------------

       Basis of Accounting:
       --------------------

       The financial statements of the Plan are prepared under the accrual basis
       of accounting.

       Investment Valuation:
       ---------------------

       The Harsco Corporation Common Stock Fund is stated at market value, which
       represents the closing price of the stock on the Composite Reporting Tape
       of the stock exchanges on the last day of trading of the calendar year.
       Shares in the American Funds EuroPacific Growth Fund, American Funds
       Growth Fund of America, Ariel Appreciation Fund, Dodge & Cox Stock Fund,
       Morgan Stanley Institutional Fund, Inc. U.S. Real Estate Fund, Neuberger
       Berman Genesis Fund, PIMCO Total Return Fund, Putnam Bond Index Fund,
       Putnam Fund for Growth and Income, Putnam Income Fund, Putnam Money
       Market Fund, Putnam New Opportunities Fund, Putnam Voyager Fund, Vanguard
       Institutional Index Fund, Putnam Retirement Ready Funds and T. Rowe Price
       Retirement Funds are valued at net asset value, which represents fair
       value. Cash, which represents funds held until purchases of common stock
       are completed, is stated at fair value. Participant loans are valued at
       cost which approximates fair value.

       Payment of Benefits:
       --------------------

       Benefit payments to participants are recorded when paid.

       Use of Estimates:
       -----------------

       The preparation of financial statements in conformity with generally
       accepted accounting principles 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
       financial statements and the reported amounts of additions and deductions
       during the reporting period. Actual results could differ from those
       estimates.

       Income Recognition:
       -------------------

       The Plan presents in the Statement of Changes in Net Assets Available for
       Benefits the net appreciation (depreciation) in the market value of its
       investments which consists of the realized gains or losses and the
       unrealized appreciation (depreciation) on those investments.

2.     Summary of Significant Accounting Policies: (continued)
       -------------------------------------------------------

       The purchase and sale of investments are recorded on a trade-date basis.
       Dividend income is recorded on the ex-dividend date. Income from other
       investments is recorded as earned on an accrual basis. Both participant
       contributions and Company matching contributions are accrued in the
       period of the related payroll deductions. Forfeitures, a result of
       participant withdrawals prior to their full vesting in the Plan, are used
       to reduce the amount of future Company matching contributions. In 2006,
       forfeited amounts of $60,064 were used to offset Company matching
       contributions and $6,221 remained in a money market fund at December 31,
       2006 to be used to offset future Company matching contributions.


3.     Investments:
       ------------

       The following table separately identifies those investments which
       represent five percent or more of the Plan's net assets at December 31,
       2006 with comparable information for 2005:

                    ----------------------------------------


4.     Related-Party Transactions:
       ---------------------------

       Certain Plan investments are shares of mutual funds managed by Putnam
       Investments. Putnam Investments is a sister company of Mercer Human
       Resource Services which is the trustee and record keeper for the plan.
       Transactions in these funds qualify as party-in-interest transactions.

       Transactions in the Harsco Corporation Common Stock Fund also qualify as
       party-in-interest transactions. The Plan purchased $12,315,765 and sold
       $16,612,632 of Company stock during the year ended December 31, 2006.


5.     Plan Amendments:
       ----------------

       The Company amended the Plan effective January 1, 2004, to include
       rollover contributions when determining whether a Participant's account
       exceeds $5,000. This threshold is used to determine if a Participant's
       balance will be immediately paid-out to the Participant upon the
       Participant leaving employment with the Company or if it will remain in
       the Plan until the Participant chooses to withdraw it.

       March 28, 2005, the Plan was amended to limit the amount that can
       automatically be paid out in a lump sum payment to $1,000 and to allow a
       voluntary election of a lump sum payment of amounts not exceeding $5,000
       without the consent of the Participant's spouse. In addition, the Company
       amended the Plan effective December 29, 2005, to provide Company
       contributions as required under collective bargaining agreements for the
       newly acquired participants of the Brambles USA, Inc Company.

       January 1, 2006, the Plan was amended to allow for profit sharing
       contributions to groups of employees as either required under collective
       bargaining agreements or as determined by the Board, to permit profit
       sharing contributions to be available for loans as required under
       collective bargaining agreements, to permit expanded safe harbor hardship
       withdrawals for funeral and casualty expenses and expedited hardship
       withdrawals for certain participants impacted by the effects of Hurricane
       Katrina, to suspend contributions for 6 months following hardship
       withdrawals, to comply with the requirement that Non-Discrimination
       Testing procedures must be included in the Plan document, and to grant to
       the Benefits Committee to adopt Plan amendments which are needed due to
       regulatory changes and which have no substantial adverse financial impact
       upon the Employer of the Plan.


6.     Federal Income Taxes:
       ---------------------

       The Company received a determination letter from the Internal Revenue
       Service on May 15, 2003, that the Plan, as amended March 28, 2003, is a
       qualified plan under Sections 401(a) and 401(k) of the Internal Revenue
       Code and is therefore exempt from Federal income taxes under the
       provisions of Section 501(a). The determination letter renewed the IRS's
       previous favorable determination made on December 26, 2000. During
       January 2007 the Plan and all amendments to date were submitted to the
       IRS for a new determination letter. At the time of this report, the new
       determination letter has not been received, however, the Plan
       administrator and the Plan's tax counsel believe that the Plan is
       designed and is currently being operated in compliance with the
       applicable provisions of the Internal Revenue Code.

7.     Subsequent Events:

       Ready 2055, these funds were added as new investment options for
       participants effective April 16, 2007.


8.     Risks and Uncertainties:
       ------------------------

       The plan invests in various investment securities. Investment securities
       are exposed to various risks such as interest risk, market and credit
       risks. Due to the level of risk associated with certain investment
       securities, it is at least reasonably possible that changes in the values
       of investment securities will occur in the near term and that such
       changes could materially affect the amounts reported in the statement of
       net assets available for benefits.
