The sole issue raised in this bankruptcy appeal is whether, in a reclamation action brought pursuant to 11 U.S.C. § 546(c), the seller must prove as part of its prima facie case that the debtor possessed the goods the seller seeks to reclaim at the time the reclamation demand was made. We conclude that an implicit requirement of a § 546(c) reclamation claim is that the debtor must possess the goods when the reclamation demand is made and therefore that the seller must prove possession as part of its prima facie case. Thus, we affirm.
I. BACKGROUND
Flav-O-Rich Inc. (“Flav-O-Rich”) sold and delivered milk products and ice cream (“reclamation goods”) to Rawson Food Service, Inc. (“Rawson”), a retail food chain, daily between February 11 and February 19,1986. The aggregate value of the delivered products was approximately $102,000. Rawson filed a petition under Chapter 11 of the Bankruptcy Code on February 19, 1986. The following day, Flav-O-Rich made a written demand for reclamation of the goods it had delivered to Rawson on or after February 11, 1986. Rawson did not comply with the reclamation demand.
*1345Consequently, Flav-O-Rich commenced this reclamation action in the Bankruptcy Court for the Middle District of Florida on February 27, 1986. Pursuant to 11 U.S.C. § 546(c)1 and Fla.Stat. § 672.2-702(2)2, Flav-O-Rich sought either an order requiring Rawson to return the reclamation goods or, in the alternative, an order granting it either an administrative priority or a lien on Rawson’s unencumbered assets in an amount sufficient to satisfy its reclamation demand. Flav-O-Rich’s complaint alleged that Rawson had entered Chapter 11 proceedings February 19, 1986, that in the ten days prior to the reclamation demand Flav-O-Rich had sold and delivered the reclamation goods to Rawson, that Rawson was insolvent during the entire period in which the reclamation goods were sold and delivered, that Flav-O-Rich hand-delivered a written demand for reclamation to Raw-son on February 20,1986, and that Rawson had failed to return the reclamation goods.
In its answer to Flav-O-Rich’s complaint, Rawson denied that it was insolvent when the goods were delivered and claimed that it had no knowledge of the total value or delivery dates of the reclamation goods. Paragraph 10 of the answer read as follows:
Affirmative Defenses
10. The Complaint for Seller Reclamation should be dismissed for failure to state a claim upon which relief can be granted, including but not limited to the reason that plaintiff has failed to allege that RFS [Rawson] was in possession of the goods when the reclamation demand was made.
Following discovery, the parties stipulated that Flav-O-Rich’s reclamation demand met the requirements of § 546(c) and Fla.Stat. § 672.2-702(2)3, that Flav-O-Rich would not be required to prove Rawson’s insolvency, that Rawson took physical possession of the milk products and ice cream, and that Rawson did not comply with the reclamation demand. The parties also stipulated as to the value of the reclamation goods.
The trial commenced in August 1986, with Flav-O-Rich’s presentation of its case-in-chief. Flav-O-Rich presented evidence which showed that Rawson took possession of the reclamation goods between two and ten days prior to receiving the reclamation demand. Flav-O-Rich also presented evidence which showed that Rawson did not have a daily inventory system which would show a daily inventory of products categorized by supplier. Flav-O-Rich also offered evidence which showed that Rawson made no effort to inventory or segregate the reclamation goods from other store products following its receipt of the reclamation demand. However, the record also indicates that Flav-O-Rich had available, but did not utilize, discovery tools which could have adduced evidence relevant to the crucial issue of what reclamation goods remained in possession on the date Rawson received the reclamation demand.4 No evidence was presented to *1346show that Rawson possessed some or all of the reclamation goods when it received the reclamation demand.
At the conclusion of Flav-O-Rich’s casein-chief, Rawson moved for an involuntary dismissal of the case pursuant to Bankruptcy Rule 7041.5 Rawson contended that Flav-O-Rich failed to present a prima facie case for reclamation because it did not present any proof that Rawson possessed the reclamation goods when it received the reclamation demand. The Bankruptcy Court granted the involuntary dismissal and the District Court affirmed. Flav-O-Rich now appeals.
II. DISCUSSION
The question before us is whether the Bankruptcy Court, affirmed by the district court, erred in its conclusion that Flav-O-Rich failed to present a claim upon which relief could be granted because it did not present any proof in its case-in-chief that Rawson possessed the reclamation goods when it received Flav-O-Rich’s reclamation demand. To determine the requisite elements of a seller’s prima facie case for reclamation, we must look to § 546(c) of the Bankruptcy Code and the case law interpreting it.
Section 546(c) of the Bankruptcy Code provides the exclusive remedy for a seller who seeks to reclaim goods from a debtor in bankruptcy. In re Rozel Industries, Inc., 74 B.R. 643, 646 (Bkrtcy.N.D.Ill.1987).6 Although the § 546(c) reclamation right is “akin to that provided by the Uniform Commercial Code,”7 In re Deephouse Equipment Co., Inc., 22 B.R. 255, 258 (Bkrtcy.D.Conn.1982), compliance with the U.C.C. requirements is insufficient to allow reclamation unless the § 546(c) requirements also are met. Id.; In re Charter Co., 52 B.R. 263, 265-66 (Bkrtcy.M.D.Fla.1985) (“Charter I”); In re Flagstaff Food-*1347N.Y.1986) (“Flagstaff II”). The primary differences between § 546(c) of the Bankruptcy Code and § 2-702(2) of the U.C.C. are that the U.C.C. waives the ten-day prior notice requirement if the buyer fraudulently misrepresents its solvency to the seller within three months prior to the receipt of the goods and that the U.C.C. does not specify that the reclamation demand must be in writing. See In re Flagstaff Food-service Corp., 14 B.R. 462, 467 (Bkrtcy.S.D.N.Y.1981) (“Flagstaff I”)-, Matter of AIC Photo, Inc., 57 B.R. 56, 59 (Bkrtcy.E.D.N.Y.1985); In re Landy Beef Co., Inc., 30 B.R. 19, 20 (Bkrtcy.D.Mass.1983).
It is settled in the case law that the seller is required to establish the following in order to reclaim goods from a debtor in bankruptcy pursuant to § 546(c): (1) a statutory or common law right to reclaim the goods; (2) the debtor’s insolvency when it received the goods; and (3) a written reclamation demand made within ten days after the debtor received the goods. See, e.g., In re New York Wholesale Distributors Corp., 58 B.R. 497, 500 (Bkrtcy.S.D.N.Y. 1986) (“the conditions imposed by Code § 546(c) on a seller who seeks to recover goods sold and delivered to a debtor may be briefly summarized as follows....” (listing above requirements) (emphasis added)); In re Rozel Industries, Inc., 74 B.R. at 646 (“the seller must meet the following re-quirements_” (listing above requirements) (emphasis added)); Flagstaff II, 56 B.R. at 905. The parties agree that all of the above requirements are satisfied in this case.8
It also is well established that a seller cannot reclaim goods which the debt- or does not possess when it receives the reclamation demand. See In re Coupon Carriers Co., 77 B.R. 650, 652 (N.D.Ill. 1987); In re Wheeling-Pittsburgh Steel Corp., 74 B.R. 656, 659 (Bkrtcy.W.D.Pa.1987) (“the seller may only reclaim ‘the goods’ in the buyer’s possession on the date the written demand for reclamation is made.”); In re Bosler Supply Group, 74 B.R. 250, 252 (N.D.Ill.1987) (“various courts have also required that the goods be in the debtor’s possession at the time of the demand.”); Archer Daniels Midland Co. v. Charter International Oil Co., 60 B.R. 854, 856 (M.D.Fla.1986) (“the predominant view allows a seller to reclaim only those goods which are identifiable and in the buyer’s possession at the time the reclamation demand is received.”); In re New York Wholesale Distributors Corp., 58 B.R. at 500 (“the courts have consistently required that the goods still be in the debtor’s possession at the time the demand for reclamation is received.”); Flagstaff II, 56 B.R. at 908 n. 7 (“It is well settled that the seller may only reclaim such goods actually on hand at the time of the demand.”); Oliver Rubber Co. v. Griffin Retreading Co., Inc., 56 B.R. 239, 241 (D.Minn.1985) (“A seller seeking reclamation ... must make a demand for the goods ... while the goods remained in the insolvent buyer’s possession.”), affd sub nom. In Re: Griffin Retreading Co., 795 F.2d 676 (8th Cir.1986); In re Charter Co., 54 B.R. 91, 92 (Bkrtcy. M.D.Fla.1985) (“Charter II”) (“Implicit within § 546 is the additional requirement that the goods be identifiable and in the possession of the debtor on the day of demand.”); In re Lawrence Paperboard Corp., 52 B.R. 907, 910 (Bkrtcy.D.Mass. 1985) (“In addition, the goods must actually exist and be intact in the hands of the debtor at the time of the demand....”); Charter I, 52 B.R. at 265; In re Furniture Distributors, Inc., 45 B.R. 38, 45 (Bkrtcy. D.Mass.1984); In re Bensar Co., Inc., 36 B.R. 699, 701 (Bkrtcy.S.D.Ohio 1984) (“reclamation rights only extend to the [goods] remaining in the debtor’s possession....”); In re Landy Beef Co., Inc., 30 B.R. at 21 (“In order to be the object of a reclamation action, goods must be identifiable and in the possession of the debtor on the day of demand.”); In re Davidson Lumber Co., 22 B.R. 775 (Bkrtcy.S.D.Fla.1982); Flag*1348staff I, 14 B.R. 462. We agree with the numerous bankruptcy and district court decisions cited above and hold that a seller can reclaim only those goods the debtor possessed when it received the reclamation demand.
There also is substantial support in the case law that the seller bears the burden of proving possession. For example, in Flagstaff II the court explicitly held that the burden of proof of possession is on the seller. 56 B.R. at 908. The Court explained that:
[The seller] shoulders the burden of proving that [the debtor] had in its possession the goods at the time demand was made. [The seller’s] evidence must indicate that this critical fact on which its recovery depends is true, and not merely that it is possible it is so_ Moreover, testimony heard at trial regarding this disputed fact must be viewed in the light most favorable to [the debtor].
Id. (citations omitted; footnote omitted).
In Charter II, the court concluded that a seller’s right to reclaim goods under § 546(c) is implicitly conditioned on a showing that the goods were identifiable and in the debtor’s possession when it received the reclamation demand. 54 B.R. at 92. The court expressly placed the burden of proving possession on the seller:
This Court finds that the identification requirement mandates [the seller] tracing the crude oil from its possession into an identifiable mass.... If the mass of crude oil is subject to [the debtor’s] control then it is both “identifiable” and “in the possession of the debtor.”
Id. at 93 (emphasis supplied). This holding that the seller must trace the goods from its possession to the debtor’s possession was favorably noted by the court in In re Mesa Refining, Inc., 66 B.R. 36, 14 B.C.D. 1177, 1178 (Bkrtcy.D.Colo.1986) and was expressly followed in In re Wheeling-Pittsburgh Steel Corp., 74 B.R. 656, 660-61 (Bkrtcy. W.D.Pa.1987).
Several courts implicitly have placed the burden of proof of possession on the seller. For example, in In re New York Wholesale Distributors, 58 B.R. 497 (Bkrtcy.S.D.N.Y. 1986), after noting the three conditions (listed above) that the statutory language of § 546(c) expressly imposes on a seller, the Court explained that “[i]n addition, the courts have consistently required that the goods still be in the debtor’s possession at the time the demand for reclamation is received.” Id. at 500. We interpret this to mean that proof of the debtor’s possession was a requisite fourth element of the seller’s claim. Similarly, in In re Bosler Supply Group, the court listed possession by the debtor at the time of the reclamation demand as one of the “rather stringent requirements for reclamation” that the seller had to meet in order to reclaim the goods. 74 B.R. at 252-53. Likewise, in In re Landy Beef Co., Inc., 30 B.R. at 20 n. 4, the court described possession on the date of the reclamation demand as “a third requirement in order to maintain a successful reclamation action.”
Flav-O-Rich does not seriously contest that, at some point during the trial, it must prove that Rawson possessed the reclamation goods when it received the reclamation demand; rather, it argues that possession is not part of its prima facie case and that Rawson bears the burden of producing evidence of the lack of possession. These arguments are without merit.
First, as discussed above, a valid reclamation claim requires possession of the goods by the debtor when it receives the reclamation notice. Possession necessarily is part of the prima facie case which the seller must present in a § 546(c) reclamation action. The seller therefore bears the burden of producing some evidence of possession when it presents its case-in-chief. If the seller presents evidence of possession in its case-in-chief, the debtor then can present contrary evidence in its rebuttal case. The seller bears the burden of proof, thus if the evidence is in equipoise, the debtor prevails.
Second, Flav-O-Rich’s burden of production argument is based on the erroneous proposition that lack of possession is *1349an contrary, possession is an integral element of a seller’s reclamation claim and therefore is a necessary part of the seller’s prima facie case, as we hold above. A defense which points out a defect in the plaintiff’s prima facie case is not an affirmative defense.9 As the Sixth Circuit explained in Ford Motor Co. v. Transport Indemnity Co., 795 F.2d 538, 546 (6th Cir.1986):
An affirmative defense raises matters extraneous to the plaintiff’s prima facie case; as such, they are derived from the common law plea of ‘confession and avoidance.’ 5 C. Wright and A. Miller, Federal Practice and Procedure § 1270, at 289 (1969). On the other hand, some defenses negate an element of the plaintiff’s prima facie case; these defenses are excluded from the definition of affirmative defense in Fed.R.Civ.P. 8(c). 2A J. Moore and J. Lucas, Moore’s Federal Practice Till 8.27[1], 8.27[4] (2d ed.1985).
(emphasis in original). In addition, it is well established that “[t]he party asserting an affirmative defense usually has the burden of proving it.” Drexel Burnham Lambert Group Inc. v. Galadari, 777 F.2d 877, 880 (2d.Cir.1985). Flav-O-Rich’s contention that the debtor must raise lack of possession as an affirmative defense is inconsistent with our holding that the seller bears the burden of proof of possession.
We find support in Flagstaff II, 56 B.R. 899 (Bkrtcy.S.D.N.Y.1986), for our conclusion that lack of possession is not an affirmative defense. The reclaiming seller in Flag staff lo&t the case because it presented no convincing evidence that the reclamation goods were in the debtor’s possession when it received the reclamation demand. 56 B.R. at 908. If lack of possession actually were an affirmative defense, the failure of the seller to present convincing evidence of possession would not result in a denial of its claim; it would only lose if the debtor presented convincing evidence that it did not possess the goods at the requisite time. Similarly, in In re Lawrence Paperboard Corp., 52 B.R. 907, 910-11 (Bkrtcy.D.Mass. 1985), the court noted that no evidence of several elements of a reclamation claim was presented at trial. The court specifically noted that no evidence of possession had been presented. It concluded that the seller could not reclaim its goods in the absence of such evidence. Had lack of possession been an affirmative defense, rather than a part of the seller’s prima facie case, lack of evidence of possession would not bar the seller’s recovery.10
III. CONCLUSION
In summary, we conclude that a seller must prove as part of its prima facie case that a debtor possessed the reclamation goods when it received the seller’s written reclamation demand. We also conclude that the seller bears the ultimate burden of proof of possession. In the instant case, Flav-O-Rich did not allege in its complaint that Rawson possessed the goods when it received the reclamation notice. At trial, Flav-O-Rich did not present any evidence of Rawson’s possession at the time of demand, despite the fact that it was on notice by virtue of paragraph 10 of Rawson’s answer that possession would be an issue in the case. Because Flav-O-Rich *1350never asserted that Rawson possessed the milk products and ice cream when it received the reclamation demand nor adduced any evidence at trial that supported a finding of possession, we conclude that the bankruptcy court correctly granted Raw-son’s motion for an involuntary dismissal of the case.11
For the foregoing reasons, the judgment of the district court is
AFFIRMED.
