Before MURPHY, MELLOY, and GRUENDER, Circuit Judges.
                           ___________

MURPHY, Circuit Judge.

       The Missouri Board of Examiners for Hearing Instrument Specialists (the
Board) brought this action against Hearing Health Express (Hearing Express), an
Illinois corporation, to enjoin it from selling hearing aids to residents of Missouri
without the prior fitting or testing required by state law. Hearing Express argued in
response that the Missouri statute was preempted by the Medical Devices Amendment
to the Federal Food, Drug and Cosmetic Act and that it violated the dormant
Commerce Clause. Both parties moved for summary judgment. The district court
granted the Board's motion and issued a permanent injunction. Hearing Express
appeals, and we reverse.
       Hearing Express is an Illinois corporation that is in the business of selling
hearing aids through the mail and on the internet, including sales to customers in
Missouri. It has no employees or facilities in Missouri and conducts all of its business
with Illinois licensed hearing aid dispensers. It is undisputed that Hearing Express
conducts its business in full compliance with the applicable federal law and
regulations, which require either a presale hearing evaluation by a physician or a
signed waiver of such an evaluation from the consumer seeking a hearing aid.

       The state of Missouri regulates the sale of hearing instruments within its borders
under Missouri Statute § 346.110(1). This statute prohibits the sale of hearing aids
through the mail without prior fitting and testing by a Missouri licensed hearing
instrument specialist, and it does not contain a written waiver option. In March 2002
the Central Investigations Unit of the Missouri Division of Professional Registration
(CIU) purchased a hearing aid from Hearing Express using a fictitious name. The
CIU received the hearing aid without a prior fitting or testing by a Missouri licensed
specialist as required by the state statute. In February 2004 the Board sued Hearing
Express in state court seeking both a preliminary and a permanent injunction. Hearing
Express removed the case to the federal district court on the grounds that the Missouri
statute is preempted by the Medical Devices Amendment (MDA), 21 U.S.C. § 360(k),
to the Federal Food, Drug and Cosmetic Act (the Act) and that it violates the
Commerce Clause. Both parties then moved for summary judgment.

       The district court granted summary judgment in favor of the Board and
permanently enjoined Hearing Express from selling hearing aids in Missouri without
complying with the Missouri statute. The district court did not consider § 360k(a) to
be an express preemption statute and concluded that it is not preempted by the MDA
because the state requirements for fitting procedures are not covered by the federal
law, relying on Smith v. Pingree, 

(5th Cir. 1981). The district court
also ruled that the Missouri statute does not violate the Commerce Clause since it
regulates evenhandedly and its burdens on interstate commerce do not outweigh the


                                          -2-
benefits to consumers or the state interest in regulating professionals within its
borders. This appeal followed.

       Hearing Express contends on its appeal that the Missouri statute is preempted
by the MDA and regulations promulgated under it because the state law falls directly
within the express preemption language of the federal statute. Hearing Express asserts
that the Food and Drug Administration (FDA), acting under the authority delegated
to it by Congress, has specifically rejected any requirement for mandatory
audiological evaluations before the sale of hearing aids. See 45 Fed. Reg. 67329-
67330. Appellant also points out that after the passage of the MDA, the FDA
concluded that statutes which require mandatory audiological evaluations are
preempted and it denied exemptions from the MDA's preemptive reach to states with
statutes similar to Missouri's. 

The Board responds that the district
court correctly concluded that the Missouri law is not preempted because the federal
statute does not regulate the fitting and testing of hearing aids. Appellee urges that the
judgment be affirmed. We review challenges to summary judgment de novo, taking
the record in the light most favorable to the responding party. Larson v. Kempker, 

, 939 (8th Cir. 2005).

       A state law may be either expressly or impliedly preempted by federal law.
Express preemption exists when a federal law explicitly prohibits state regulation in
a particular field. Implied preemption arises when a federal law completely occupies
the field of regulation so that by implication there is no room for state regulation and
the coexistence of federal and state regulation is not possible. See Chapman v. Lab
One, 

, 624 (8th Cir. 2004). Preemptive language in a statute is to be read
narrowly, Cipollone v. Liggett Group, Inc., 

, 518-19 (1992), and without
clear congressional intent there is a general presumption against finding implied
preemption. See Medtronic, Inc. v. Lohr, 

, 485 (1996); Cliff v. Payco
General American Credits, Inc., 

, 1125 (11th Cir. 2004); Springston v.
Consolidated Rail Corp., 

, 244 (6th Cir. 1997). Implied preemption is


                                           -3-
therefore rarely found and only when the state law is in direct conflict with or
frustrates the purposes of the federal law. See, e.g., CTS Corp. v. Dynamics Corp. of
Am., 

, 78-79 (1987).

      Whether the MDA preempts the Missouri statute depends upon the specific
language used by Congress in drafting § 360k. Section 360k(a) of the MDA provides:

      Except as provided in subsection (b)...no State...may establish or
      continue in effect with respect to a device intended for human use any
      requirement – (1) which is different from, or in addition to, any
      requirement applicable under this chapter to the device, and (2) which
      relates to the safety or effectiveness of the device or to any other matter
      included in a requirement applicable to the device under this chapter.

. § 360k(a).

       A state law will be preempted under MDA § 360k if any of its requirements (1)
are "different from, or in addition to" those in the MDA and (2) "relate[] to the safety
or effectiveness of the device or any other matter included in a requirement applicable
to the device." 21 U.S.C. § 360k(a). Subsection (b) of the statute in turn provides that
a state may petition the FDA for an exemption from its preemptive force. Since the
language used in § 360k(a) expressly prohibits certain types of state regulation, we
conclude this section of the MDA is an express preemption statute evincing
congressional intent to prohibit states without a § 360k(b) exemption from regulating
medical devices covered by the Act. See, e.g., McMullen v. Medtronic, Inc., 

, 487 (7th Cir. 2005); Brooks v. Howmedica, Inc., 

, 792 (8th Cir.
2001); New Jersey Guild of Hearing Aid Dispensers v. Long, 

, 809 (N.J.
1978); 45 Fed. Reg. at 67328.

      The Missouri statute at issue provides that "[n]o person shall (1) sell through
the mails, hearing instruments without prior fitting and testing by a hearing instrument


                                          -4-
specialist." Mo. Stat. § 346.110(1). A hearing instrument specialist is defined as "a
person licensed by the state...who is authorized to engage in the practice of fitting
hearing instruments." Mo. Stat. § 346.010(6).

       The Board does not seriously dispute that the requirements of the Missouri
statute are different from or in addition to those found in the MDA. Under the
applicable federal regulations a customer wishing to purchase a hearing aid must
either undergo an auditory evaluation or provide a signed waiver. 21 C.F.R. §
801.421(a). An auditory examination is thus optional under the MDA. See 45 Fed.
Reg. 67328-67330. The Missouri statute contains no option for a customer to submit
a waiver in lieu of an auditory examination. If acts which are permitted under the
federal scheme are made mandatory by the state, that requirement is "in addition to
the federal requirement." 

; 45 Fed. Reg. at 67327.
Although the Board claims that persons over eighteen can waive the requirement of
an auditory exam, the text of the Missouri statute provides no such option. We
conclude that the requirements in the Missouri statute are "different from or in
addition to" those prescribed by the MDA.

        The second inquiry is whether the Missouri statute relates to the safety or
effectiveness of the device or any other requirement of the MDA. The FDA has
concluded that a state requirement "of audiological evaluation relates to the safety or
effectiveness of hearing aids because it is intended to ensure that the purchaser is
fitted properly with a hearing aid." 45 Fed. Reg. at 67327. Moreover, the Board's own
witnesses admitted in deposition testimony that the Missouri statute is related to the
health of the patient and the effectiveness of the device.

      The Board nevertheless argues that the Missouri statute is not preempted
because it deals only with fitting and testing, which it says is not regulated by the
MDA. The Board relies upon a 1981 Fifth Circuit decision dealing with a since
repealed Florida statute which required certain minimum procedures and equipment


                                         -5-
in the fitting of hearing aids. 

. The Fifth Circuit
concluded that the Florida law dealt only with the mechanics of fitting rather than
presale testing and that it was not preempted because the federal regulations "did not
address the mechanics of fitting hearing aids to patients." 

We might
question whether Congress made so broad an "implied reservation of power" to the
states as Pingree suggests, 

are in any event significant distinctions
between the repealed Florida law and Missouri statute. One element of the Florida
law required that audiometric tests be conducted in a certified testing room with sound
pressure levels at specified frequencies, but unlike the Missouri statute it allowed
consumers to waive the requirement. Fl. Stat. § 468.135(7) (quoted in 

). The Florida law also had no mandatory testing requirement in contrast
to the Missouri statute which mandates presale testing without exception.

       We conclude that the requirements of Mo. Stat. § 346.110(1) are in addition to
the federal requirements applicable to the sale of hearing aids and that they directly
relate to the safety of consumers and the effectiveness of the devices. The Missouri
statute therefore "interfere[s] with the execution and accomplishment of the objectives
of the FDA's hearing aid regulation," 45 Fed. Reg. at 67327, and must be deemed
preempted by the MDA. Because of this conclusion it is not necessary to consider any
issues raised under the dormant Commerce Clause.

     For these reasons the judgment and injunction are vacated and the case is
remanded to the district court for entry of judgment in favor of Hearing Health
Express.
