Paul Ajlouny appeals from a conviction after a 17-day trial in the United States District Court for the Eastern District of New York (Mark A. Costantino, Judge) upon a jury verdict finding him guilty of transportation of stolen property in foreign commerce in violation of 18 U.S.C. § 2314 (1976). The jury was unable to reach a verdict and a mistrial was declared on the other 136 counts of the indictment, which charged Ajlouny with having used a “blue box” 1 to defraud the New York Telephone Company in violation of 18 U.S.C. § 1343 (1976). We affirm the conviction on the § 2314 count.
In March, 1978, the telephone company investigator in charge of the investigation of blue box use on Ajlouny’s phone, advised customs agent Stephen Rogers that Ajlouny had made blue box calls to various locations in the Middle East. The telephone company investigator also permitted Rogers to *833 listen to a taped conversation with the investigator in which Ajlouny requested that the blue box investigation be halted and warned that it was “stirring up a hornet’s nest,” “blowing his cover,” and endangering the lives of certain people in Israel and the United States. Through their own investigation, customs officials determined that some of the blue box calls placed from Ajlouny’s residence had been made to the headquarters of the Palestine Liberation Organization in Beirut.
In early April, Rogers and other customs agents began surveillance of Ajlouny to determine whether he was the individual who had been placing blue box calls from phone booths in the vicinity of his residence. One morning, Rogers and another customs agent followed Ajlouny to a small shopping center where, according to Rogers, they observed him “apparently supervising the loading” of a cargo container. Through independent investigation, the customs agents learned that the container was under lease to Ajlouny and was scheduled to depart for Doha, Qatar, on April 17, 1978.
In mid-April when they discovered that the container was no longer in the shopping center, Rogers and other agents proceeded to a Brooklyn pier where they located the container in a customs control area. On the day the container was scheduled to be shipped, the customs agents obtained the dock receipt, which described the contents of the container as air conditioning equipment. The agents then proceeded to unseal and search the container, 2 which had not yet been loaded on board ship. Inside the container, the agents found considerable quantities of teletype and telecommunications equipment; no air conditioning equipment was found. The same day, telephone company investigators identified some of the equipment found in the container as stolen property.
Ajlouny was arrested the day after the search and ultimately indicted for transporting stolen telecommunications equipment in foreign commerce in violation of 18 U.S.C. § 2314. After receiving his
Miranda
warnings, he admitted that he had arranged for shipment of the telecommunications equipment, but denied that the property was stolen. Prior to trial, he moved on Fourth Amendment grounds to suppress all evidence resulting from the search of the cargo container. Judge Costantino denied his suppression motion,
United States v. Ajlouny,
I.
On appeal, Ajlouny first contends that the search of the container was conducted without a search warrant and in the absence of “probable cause” or even “reasonable suspicion.” On this basis, he urges that the search was unlawful under both Fourth Amendment and federal statutory standards, and that the admission of evidence obtained from the search requires reversal of his conviction.
The Government concedes that the search was warrantless and does not dispute the defendant’s contention that it was not based on probable cause. But the Government contends, and Judge Costantino ruled,
The border search exception, at least as it applies to searches of persons and property entering the country, has enjoyed a long judicial history. As the Supreme Court observed in
United States v. Ramsey,
Border searches . . . from before the adoption of the Fourth Amendment, have been considered to be “reasonable” by the single fact that the person or item in question had entered into our country *834 from outside. There has never been any additional requirement that the reasonableness of a border search depended on the existence of probable cause. This longstanding recognition that searches at our borders without probable cause and without a warrant are nonetheless “reasonable” has a history as old as the Fourth Amendment itself. [Emphasis added].
See
United States
v.
Thirty-seven Photographs,
Until recently, the applicability of the border search exceptions to export searches, such as the one conducted by customs officials in this case, was an open question. However, in
California Bankers Ass’n v. Shultz,
The circumstances of this case establish that the border search exception applies and permits a routine search without probable cause or even reasonable suspicion. We have observed that “the precise limits of the border area depend on the particular factual situation presented by the case raising the issue.”
United States v. Glaziou,
Appellant further contends that even if constitutional standards were not exceeded, the search of the container and the subsequent seizure of its contents violated the statutory limitations of 22 U.S.C. § 401(a) (1976). 4 This statute authorizes seizure of articles exported in violation of law. It conditions this seizure authority on the existence of probable cause to believe that the articles “are intended to be or are being or have been exported ... in violation of law.” 5 The statute applies in terms to arms and munitions, but includes “other articles” and has been consistently applied to any items destined for unlawful export. 6
Though § 401(a) has been held implicitly to authorize searches as well as seizures of goods for export,
Samora v. United States,
Once the search had discovered the telecommunications equipment in a container marked for shipment abroad with papers indicating that the contents was air conditioning equipment, the agents clearly had the probable cause § 401 requires to seize and detain the items. Since the search and subsequent seizure did not violate either § 401 or the Fourth Amendment, we affirm Judge Costantino’s denial of the motion to suppress.
II.
Appellant next contends that the Government failed to prove the occurrence of a border-crossing, an event he asserts is an essential element of an offense under 18 U.S.C. § 2314. The Government concedes that the cargo container was intercepted by customs officials before it had moved beyond the borders of the United States, but argues that its burden was nevertheless met by proof that the container had been transported to a restricted customs area and placed in the possession of a shipping company with instructions that it be shipped to a foreign destination. We find the Government’s position persuasive.
The express terms of § 2314 do not indicate whether a border-crossing is a required element of the offense. The section provides, in pertinent part, that:
Whoever transports in interstate or foreign commerce any goods, wares, merchandise, securities or money, of the value of $5,000 or more, knowing the same to have been stolen, converted or taken by fraud . . . [sjhall be fined not more than $10,000 or imprisoned not more than ten years, or both [emphasis added].
The definitions of “interstate commerce” and “foreign commerce” are set out in 18 U.S.C. § 10 (1976):
The term “interstate commerce” . includes commerce between one State, Territory, Possession, or the District of Columbia and another State, Territory, Possession, or the District of Columbia.
The term “foreign commerce” . includes commerce with a foreign country.
*837
The case law is similarly ambiguous on the need for an actual crossing of the border. Courts have frequently had occasion to observe that purely intrastate transportation of stolen property will not support a conviction under § 2314,
United States
v.
Walker,
We need not decide whether the transportation element of § 2314 is satisfied by facts sufficient under § 659, since even under a more rigorous standard, the element of transportation “in foreign commerce” was established in the circumstances of this case. A shipment is sufficiently “in foreign commerce” for purposes of § 2314 once property bound for a foreign destination arrives in a customs area. There is no question that the Commerce Clause permits Congress to reach stolen goods at such a location, and we see no reason to doubt that Congress intended to do so. Even if § 2314 is concerned with the crossing of a national boundary, we believe Congress was not aiming only at stolen goods moving across a technical boundary line, but also wanted to reach shipments in the course of such a crossing, including at least goods at a dockside customs area.
III.
Ajlouny next contends that his Fourth Amendment rights were violated because of wiretapping. The Government acknowledged in the District Court that the defendant’s voice was overheard during warrant-less electronic surveillance coinciding closely in time with the commission of the offense for which he was convicted. In January, 1979, in response to the defendant’s request to check agency records to determine if he had been a target of electronic surveillance, the Government notified the defendant that his conversations had been *838 overheard by the FBI “during the course of foreign intelligence national security electronic surveillances.” Records of these conversations and descriptions of the premises which were the subject of the surveillances were submitted to the District Court ex parte for in camera inspection, with a request not to disclose them to the defendant. These submissions were accompanied by an affidavit of then Attorney General Griffin Bell, certifying that disclosure of the sealed materials “would prejudice the national interest” and representing that the surveillances had been:
authorized by the Attorney General pursuant to the power delegated to him by the President of the United States in the exercise of his authority relating to the Nation’s foreign affairs as described in 18 U.S.C. § 2511(3), to protect the Nation against actual or potential attack or other hostile acts of foreign power, to obtain counter-intelligence (including foreign) information deemed essential to the security of the United States, and to protect national security information against foreign intelligence activities.
Additional records of FBI surveillance were submitted to the District Court in May, 1979.
After reviewing the records
in camera,
Judge Costantino denied Ajlouny’s discovery and suppression motions, finding that the statements, though obtained without a warrant, were lawfully recorded during the course of foreign intelligence surveillance “of legitimate concern to the national security.”
United States v. Ajlouny, supra,
In
Alderman v. United States,
The defendant challenges the District Court’s finding on two grounds. He first contends that the Court erred as a matter of law in concluding that foreign intelligence electronic surveillance does not require a warrant. The defendant also raises the procedural objection that the subsidiary matters decided by Judge Costantino in upholding the legality of the surveillances, such as whether in fact they were conducted for national security and foreign intelli *839 gence purposes and whether they were reasonable in nature and scope, could not properly have been resolved without an adversary hearing and disclosure of relevant information. We first consider this procedural objection.
The Supreme Court has not yet decided what procedure the district courts are to follow in making threshold determinations concerning the lawfulness of electronic surveillance.
Giordano v. United States, supra,
We conclude that the
in camera
procedures employed by Judge Costantino in this case were adequate for purposes of determining the lawfulness of the FBI’s surveillance of the defendant.
12
The issues of whether the surveillance was conducted for national security and foreign intelligence purposes and whether it was reasonable in scope, were limited in nature and were not dependent on a painstaking search through “a large volume of factual materials.”
Alderman v. United States, supra,
The substantive issue of whether foreign intelligence surveillance can be conducted lawfully without a judicial warrant was specifically left undecided by the Supreme Court in
United States v. United States District Court,
The Supreme Court has determined that the primary, if not the sole, justification for the exclusionary rule is the deterrence of police conduct that violates Fourth Amendment rights.
Stone v. Powell,
We believe this is a case in which neither deterrence nor the so-called “imperative of judicial integrity” would be served by application of the exclusionary rule. The Supreme Court has determined that where “law enforcement officials reasonably believed in good faith that their conduct was in accordance with the law,” the imperative of judicial integrity is not offended by permitting unlawfully obtained evidence to be introduced at trial.
Stone
v.
Powell, supra,
The apparent good faith of those who authorized the electronic surveillance of Ajlouny also tends to undercut any deterrence that might be achieved by application of the exclusionary rule. As the Supreme Court observed in
Michigan v. Tucker,
The deterrent purpose of the exclusionary rule necessarily assumes that the police have engaged in willful, or at the very least negligent, conduct which has deprived the defendant of some right. By refusing to admit evidence gained as a result of such conduct, the courts hope to instill in those particular investigating officers, or in their future counterparts a greater degree of care toward the rights of an accused. Where the official action was pursued in complete good faith, however, the deterrence rationale loses much of its force.
See
Scott
v.
United States,
More significantly, the need to apply the exclusionary rule to achieve deterrence has been virtually eliminated by the significant clarification of standards that occurred with the enactment in October, 1978 of the Foreign Intelligence Surveillance Act of 1978, Pub.L.No.95-511, 92 Stat. 1783 (codified at 50 U.S.C. §§ 1801-1811 (Supp. II 1978)). The Act now requires with limited exceptions not relevant to this case, 14 the obtaining of a court order before foreign *842 intelligence surveillance may be conducted. Though the surveillance of Ajlouny, occurring prior to the Act’s effective date, was not subject to this or any other statutory warrant requirement, passage of the Act substantially reduced the importance of deciding in this case whether the Constitution independently requires the obtaining of a warrant for foreign intelligence electronic surveillance. Though the exclusionary rule remains available in the event the new statutory requirements are not observed, there is little if any need to apply the rule to a possible Fourth Amendment violation now that agents’ conduct in the future will normally be guided and measured by statutory standards. Application of the exclusionary rule in this case is therefore inappropriate. Consequently, we decline to adjudicate the constitutionality of warrantless foreign intelligence surveillance.
IY.
Finally, appellant contends that Judge Costantino improperly denied his motions pursuant to Fed.R.Crim.P. 8(a) and 14 for severance of the § 2314 charge from the 136 blue box counts. He urges that the two sets of counts were “unrelated” to one another, and that joinder was both improper as a matter of law and prejudicial to his right to a fair trial.
The propriety of joinder under Rule 8(a)
15
is a question of law. Improper joinder requires reversal unless the Rule 8 error was harmless.
United States v. Werner,
Having examined the Government’s pretrial representations and proof at trial, we find substantial justification for the joinder of the stolen property count with at least one of the blue box counts. Evidence was introduced at trial that the blue box call charged in count 118 of the indictment was placed to the telephone number of the company in Qatar to which the cargo container was addressed. An available inference, sufficient to justify joinder on a theory of “common scheme or plan,” is that the purpose of this call was to discuss arrangements for the shipment of the stolen communications equipment.
By contrast, the relationship of most of the other blue box calls to the common scheme or plan, particularly those placed to locations within the United States, is unclear. 16 With respect to the vast majority of the 136 calls, the Government made no effort to establish any connection to either the stolen property count or the alleged plan to set up an independent PLO telecom *843 munications network. We nevertheless conclude that even if the joinder of the stolen property count with the apparently unrelated blue box counts was improper under Rule 8(a), 17 the error was harmless.
Our previous decisions have established that an improper joinder under Rule 8 will generally constitute harmless error if “all or substantially all the evidence admitted at the joint trial would have been admissible in separate trials.”
United States v. Werner, supra,
We have considered appellant’s other claims of error and find no basis to disturb the conviction.
Affirmed.
Notes
. According to trial testimony, a blue box is a device that simulates tones used by the telephone company, thereby permitting long-distance calls to be made without generating any records and hence without incurring charges.
. At the suppression hearing, Agent Rogers testified that he also knew, prior to the search of the cargo container, that Ajlouny was affiliated with the PLO and a pro-Palestinian newspaper, had a license to carry a gun, and had previously attempted to import three guns into the State of New York.
. Appellant contends that
Swarovski
held only that departure searches are constitutional despite lack of a warrant, but did not resolve the question of whether such searches may be conducted in the absence of probable cause. We do not agree that the holding was as narrow as appellant urges. From a constitutional perspective, a search warrant will generally be required whenever probable cause is necessary for a search. The only exception is where exigent circumstances excuse the obtaining of a search warrant.
United States v. United States District Court,
This view of
Swarovski
is confirmed by the opinion’s reliance on
United States v. Stanley,
. Subsection 401(a) provides, in relevant part: Whenever an attempt is made to export or ship from or take out of the United States any arms or munitions of war or other articles in violation of law, or whenever it is known or there shall be probable cause to believe that any arms or munitions of war or other articles are intended to be or are being or have been exported or removed from the United States in violation of law, the Secretary of the Treasury, or any person duly authorized for the purpose by the President, may seize and detain such arms or munitions of war or other articles. ... All arms or munitions of war and other articles . seized pursuant to this subsection shall be forfeited. [Emphasis added].
. The structure of the statute permits a reading that renders the probable cause limitation inapplicable to some seizures. The first clause of the statute appears to permit seizure, without probable cause, “Whenever an attempt is made to export . . . articles in violation of law.” The probable cause limitation applies, in terms, when the articles are “intended to be or are being or have been exported ... in violation of law.” It may be that Congress intended to distinguish between border areas and other locations, limiting the seizure power when the articles are away from a border area, as where they are destined for export, in transit, or have arrived at their foreign destination, but placing no statutory limitation (beyond whatever the Constitution imposes) on seizure at a border area where “an attempt” to export would be expected to occur. In view of our resolution of appellant’s statutory argument, we need not rely on this possible interpretation.
. Though “primarily directed to limiting the export of war materials in protection of American neutrality and foreign policy,” § 401 has also “been consistently applied to other classes of goods.”
United States
v.
Marti,
. We have previously held that customs officials have statutory authority to conduct inspections at a point of embarkation of cargo being shipped abroad.
United States v. Chabot, supra,
. In 1953, the Act was amended to its present form. Among the most significant of the changes was the streamlining of the procedures “for effecting forfeiture and disposition of property being or intended to be exported in violation of law,” including the elimination of the warrant of detention requirement. H.R. Rep.No. 1073, 83rd Cong., 1st Sess. 1-2 (1953), reprinted in [1953] U.S.Code Cong. & Admin. News, pp. 2386, 2386-7. Though these and the other changes accomplished by the 1953 amendment were substantial, they in no way affected the original scope of the limitations of the Espionage Act, which continue to be applicable only to seizures and forfeitures.
. Some of the cases cited by the appellant contain language that supports his view concerning the necessity of a border - crossing.
United States v. Squires,
. Section 659 provides, in pertinent part, as follows:
Whoever embezzles, steals, or unlawfully takes . . . any goods or chattels moving as or which are a part of or which constitute an interstate or foreign shipment of freight, express, or other property; or . Whoever embezzles, steals, or unlawfully takes . from any railroad car, bus, vehicle, steamboat, vessel, or aircraft operated by any common carrier moving in interstate or foreign commerce or from any passenger thereon any money, baggage, goods, or chattels . Shall in each case be fined not more than $5,000 or imprisoned not more than ten years, or both . . . . [Emphasis added].
The terms “interstate commerce” and “foreign commerce” are defined in the same manner for purposes of this section as for § 2314. 18 U.S.C. § 10.
. The Court acknowledged that the disclosure of surveillance records might “compel the Government to dismiss some prosecutions in deference to national security or third-party interests,” but concluded that the requirement was nevertheless necessary to guard “against the possibility that the trial judge, through lack of time or unfamiliarity with the information contained in and suggested by the materials, will be unable to provide the scrutiny which the Fourth Amendment exclusionary rule demands.”
Alderman v. United States, supra,
Justices Harlan and Fortas dissented, in separate opinions, from the majority’s holding that the same disclosure rule applies irrespective of whether disclosure implicates national security interests.

. We need not decide whether ex
parte, in camera
proceedings are adequate for the determination of all questions bearing upon the legality of electronic surveillance. Other courts have expressed differing views on the subject. See, e.
g., United States v. Butenko,
The Foreign Intelligence Surveillance Act of 1978, Pub.L.No.95-511, which did not become effective until after completion of the surveillances in question here, provides for ex parte, in camera determination of the lawfulness of electronic surveillance, upon the filing by the Attorney General of a sworn affidavit that “disclosure or an adversary hearing would harm the national security of the United States.” Disclosure of materials to the defendant is permitted “only where . . . necessary to make an accurate determination of the legality of the surveillance.” 50 U.S.C. § 1806(f) (Supp. II 1978).
. Section 2511(3), which was repealed effective October 25, 1978 by the Foreign Intelligence Surveillance Act of 1978, Pub.L.No.95 511, Title II, § 201(c), 92 Stat. 1797 provided as follows:
Nothing contained in this chapter or in section 605 of the Communications Act of 1934 . shall limit the constitutional power of the President to take such measures as he deems necessary to protect the Nation against actual or potential attack or other hostile acts of a foreign power, to obtain foreign intelligence information deemed essential to the security of the United States, or to protect national security information against foreign intelligence activities. Nor shall anything contained in this chapter be deemed to limit the constitutional power of the President to take such measures as he deems necessary to protect the United States against the overthrow of the Government by force or other unlawful means, or against any other clear and present danger to the structure or existence of the Government.
. Subsections 1802(a)(l)(A)(i) and (a)(l)(A)(ii) of Title 50 permit foreign intelligence electronic surveillance without a court order only where the surveillance is solely directed at either the “acquisition of the contents of communications transmitted by means of communications used exclusively between or among foreign powers,” or the “acquisition of technical intelligence, other than the spoken communications of individuals, from property or premises under the open and exclusive control of a foreign power.” The FBI’s surveillance of Ajlouny fell within neither of these categories.
. Rule 8(a) provides:
Two or more offenses may be charged in the same indictment or information in a separate count for each offense if the offenses charged, whether felonies or misdemeanors or both, are of the same or similar character or are based on the same act or transaction or on two or more acts or transactions connected together or constituting parts of a common scheme or plan.
. The Government did attempt to introduce evidence at trial that one of the numbers called with a blue box from the Ajlouny residence was used by the PLO headquarters in Beirut, Lebanon. The number appears in six of the counts charged in the indictment. Judge Costantino declined to admit the proferred evidence.
. The 136,blue box counts represent offenses of a “similar character” and therefore were properly joined with each other under Rule 8(a). This does not necessarily mean, however, that all the 136 blue box counts were properly joined with the stolen property count. Though at least one of the blue box counts and the stolen property count were joinable as parts of a common scheme or plan, most of the other blue box counts had no apparent connection or similarity to the stolen property count. Our finding of harmless error makes it unnecessary to consider whether joinder was proper on a theory that counts joinable to common counts are joinable to each other.
