We are once again called upon to interpret § 4(5) of the Carriage of Goods by Sea Act, 46 U.S.C. § 1304(5) (1982) (“COGSA” or “the Act”), which limits the carrier’s and ship’s liability to “$500 per package ..., or in case of goods not shipped in packages, per customary freight unit,” unless the shipper explicitly declares a higher value. Appellant here, a Netherlands ocean carrier, appeals from a judgment of the Southern District of New York awarding $80,-332.00 damages against it after a bench trial before Judge Abraham D. Sofaer, based on its role in the untimely death of more than 10,000 plants shipped overseas in two containers on board its ship, the M.V. “Nedlloyd Rotterdam.” The district court applied the $500 “per package” limit of § 4(5). We hold instead that the plants were “goods not shipped in packages” within the meaning of the Act and accordingly reverse and remand the case for a determination of damages limited to $500 “per customary freight unit” used in shipments of this type.
In June 1980, appellee Binladen BSB Landscaping (“Binladen”), a Swiss company, contracted with appellant Nedlloyd Lijnen B.V. (“Nedlloyd”) to ship ten refrigerated containers loaded with plants from two locations in the United States to Saudi Arabia, where the plants were to adorn the рalace grounds of that country’s crown prince, who is now its king. Binladen and its agents packed and filled the containers, which were delivered to Nedlloyd and loaded on the M.V. “Nedlloyd Rotterdam,” a fully containerized vessel, for the journey. *1009 Although most of the plants in eight of the ten containers arrived in Saudi Arabia intact and healthy, those within the remaining two containers were brittle and lifeless when opened and inspected by a Binladen employee in Jeddah.
In early 1982 Binladen brought a maritime action in the Southern District of New York for damages against Nedlloyd and against the M.V. “Nedlloyd Rotterdam.” 1 Nedlloyd denied responsibility for thе plants’ death and also asserted an affirmative defense based on the limited liability provision of COGSA. In a pretrial memorandum of law Nedlloyd argued that neither container carried “packages”; rather, it contended, each of the two containers was a “package” in which the plants inside were shipped. Nedlloyd therefore claimed that its liability was limited to $500 per container. Alternatively it proposed that the plants were “goods not shipped in packages” and that its liability accordingly must be limited to $500 per customary freight unit, which it contended was also the container. Binladen counter-аrgued that the plants were individually prepared for shipping and that each therefore counted as a package under COGSA. It also argued that deficiencies in Nedlloyd’s bill of lading served to strip the carrier of the benefit of COGSA’s liability limits.
At trial in 1984 before Judge Sofaer, virtually all of the six days of testimony was devoted to evidence on liability. Evidence pertaining to the COGSA limitations on liability came out almost entirely in the exhibits, including the bills of lading and several depositions submitted in evidence during the trial. The latter show that one of the containers whose contents perished was the single container shipped from Houston, number ITLU-720073-6. Its bill оf lading described the contents as follows:
PARTICULARS FURNISHED BY THE SHIPPER
NO. OF PKGS. DESCRIPTION OF PACKAGES AND GOODS
1 40' REEFER CONTAINER SAID TO CONTAIN: 7,990
LIVE PLANTS
The other spoiled container had been shipped from Miami under a bill of lading that covered five containers. That bill described a similar type of shipment:
PARTICULARS FURNISHED BY THE SHIPPER NO. OF PKGS. DESCRIPTION OF PACKAGES AND GOODS
5/40' REEFER CONTAINERS SAID TO CONTAIN 11735 PCS. LIVE PLANTS MISC. AND 24 PKGS. SHADE CLOTH
Further itemization in the “Description” column listed the “NO. PCS.” in the container in which plants died, SCXU-488906, as 2436.
Deposition testimony introduced at trial revealed that the Houston container was loaded chiefly with cacti and that the Miami container carried nearly twenty sorts of plants and trees. Although the parties agreed that the Miami plants were individually potted, 2 they disputed the nature of the packing of the plants in the Houston con *1010 tainer. The deposition testimony of Antonio Eduardo Ramirez, the owner of Garden World Nursery in Laredo and the individual who had loaded the Houston container, included an item-by-item breakdown of the packing methods used. Read in conjunction with the nursery invoices for the sale, this testimony revealed that approximately 2,000 items were individually boxed, tied, or wrapped, more than 2,000 others had been boxed or tied in an unspecified manner, and the remainder had simply been stacked into piles. 3 Ramirez indicated that large sheets of cardboard, approximately 2V2' by 4', had been used to separate different kinds of plants and different sections of the container.
Except for reference to the number of containers and plants, none of the foregoing information appeared on the bills of lading. Moreover, the deposition testimony of Philip Elsazsser, the former Binladen employee who had inspected the sorry car *1011 go remnants in Jeddah and who had actually walked through the Houston container, related that he saw no individual pots or boxes in that container. In support of that testimony, Binladen offered photographs taken by Elsazsser during the inspection. No boxes or individual wrapping or tying are evident in thesе photographs.
The bills of lading setting forth the shipping contracts between Binladen and Nedlloyd were on the standard form employed by Nedlloyd. These forms, in small print on the back, included a “U.S.A. CLAUSE” that expressly incorporated the provisions of COGSA, although it did not explicitly recite the $500 package limit. A blank space on the front of each bill of lading was labeled “EXCESS VALUATION” and referred the reader to a clause on the reverse side setting forth a £100 sterling liability limit per package or unit. Still another provision limited liability to $2 per kilo gross weight. The parties stipulated that Binladen prepaid to Nedlloyd $14,-245.36 each for the five refrigerated containers shipped from Miami under the one bill of lading and $15,420.50 for the transport of the refrigerated container shipped from Houston.
Judge Sofaer found that the carrier had failed to ensure that the proper temperatures, humidity and ventilation conditions were maintained in the containers during the voyage, and he therefore held Nedlloyd responsible for the loss.
This appeal followed. On appeal, Nеdlloyd does not dispute Judge Sofaer’s conclusion on liability; it argues only that the Judge incorrectly awarded damages in excess of those permitted by COGSA’s § 4(5).
Discussion
Since the enactment of COGSA half a century ago courts have struggled to interpret § 4(5) of the Act, which drastically limits the liability of carriers and ships as follows:
“Neither the carrier nor the ship shall in any event be or become liable for any loss or damage to or in connection with the transportation of goods in an amount exceeding $500 per package ..., or in case of goods not shipped in packages, per customary freight unit, ... unless the nature and vаlue of such goods have been declared by the shipper before shipment and inserted on the bill of lading. This declaration, if embodied in the bill of lading, shall be prima facie evidence, but shall not be conclusive on the carrier.
“By agreement between the carrier, master, or agent of the carrier, and the shipper another maximum amount than that mentioned in this paragraph may be fixed: Provided, That such maximum shall not be less than the figure above named. In no event shall the carrier be liable for more than the amount of damage actually sustained. >)
46 U.S.C. § 1304(5).
In resolving disputes between shippers and carriers over the consequences of the $500 per package limit on carrier liability the principal difficulty has lain in defining the meaning and scope of the word “package,” a term left undefined by Congress. That
*1012
problem has been exacerbated by the adoption of new methods of preparing and assembling goods for shipment.
Allied International American Eagle Trading Corp. v. S.S. “Yang Ming, ”
At the outset we are governed by some basic principles that have been judicially developed for resolution of issues of the type before us. The first of these, rather obvious, is that the touchstone of our analysis should be the contractual agreement between the parties, as set forth in the bill of lading.
See Allied International American Eagle Trading Corp. v. S.S. “Yang Ming,’’ supra,
Secondly, no controlling definition of the term “package” has been judicially developed other than the requirement that it be the result of some “preparation [of the cargo item] for transportation ... which facilitates handling, but which does not necessarily conceal or completely enclose the goods.”
Aluminios Pozuelo Ltd. v. S.S. Navigator, supra,
Thirdly, since the prevalent large metal shipping container furnished by a carrier is “functionally part of the ship,”
Leather’s Best, Inc. v. S.S. Mormaclynx,
Lastly, absent an agreement in the bill of lading as to packaging of the cargo, goods placed in containers and described as not separately packaged will be classified as “goods not shipped in packages,” for which the $500 liаbility limit would be per “customary freight unit.”
Watermill Export, Inc. v. MV “Ponce,” supra,
Applying the foregoing principles to the present case, although the bills of lading listed in the column entitled “No. of Pkgs.” the number of containers shipped and revealed the total number of plants in the containers, they gave no indication whether or how the plants were packaged. The case is therefore significantly different from Smythgreyhound, Mitsui & Co., Ltd., and other decisions cited supra, in which the bill of lading listed not only the number of containers but the number of items qualifying as packages (i.e., connoting preparation in some way for transport), such as “bundles,” “cartons,” or the like. We cannot accept Binladen’s contention that thе reference in the bills of lading to the number of plants qualifies each plant as a separate COGSA package. 6
*1014
It is true that some of the plants were in fact prepared for shipment in ways that might have entitled them, if properly described in the bill of lading, to treatment as packages as defined in
Aluminios Pozuelo, Ltd. v. S.S. Navigator, supra.
7
But the word “plant,” standing alone in a bill of lading, does not describe an item that has been packaged for transport. Nor can a carrier that has agreed to transport a container described in the bill of lading as filled with a certain number of “live plants” reasonably infer from this description that each plant has been so packaged.
8
Some plants may be simply stowed or stacked without potting, tying, wrapping or other preparation for shipping, in which event they are not individual packages but rather “goods not shipped in packages.”
Cf. Watermill Export, Inc. v. MV “Ponce, ” supra,
There remains the question, reserved in
Mitsui’s
footnote 18 and in
Smythgreyhound,
of whether, when a bill of lading lists only the number of containers under “No. of Pkgs.” and does not describe the cargo in terms of items that can reasonably be understood as packages, the parties must be deemed to have agreed that each container constitutes a COGSA package. The principal argument against so holding is our repeatedly-expressed reluctance for sound reasons to treat a container as a package.
See Mitsui, supra,
“when the bill of lading expressly refers to the container as one package, or when the parties fail to specify an alternative measure of the ‘packages’ shipped, the courts have no choice but to respect their express or implied understanding and to treat the container as a single package.”672 F.2d at 1061 .
Moreover, we have held a container to be a COGSA package when it contained unpacked household goods that would, absent a container, have been shipped in a crate of comparable size.
Rosenbruch v. American Export Isbrandtsen Lines, Inc.,
Upon balancing these conflicting considerations we are satisfied, notwithstanding our traditional reluctance to treat a container as a COGSA package, that the terms of the bill of lading should govern; if the bill of lading lists the container as a package and fails to describe objects that can reasonably be understood from the description as being packages, the container must be deemed a COGSA package. This rule not only accords with the 1968 Brussels Protocol,
supra,
but has the virtue of certainty. As we have nоted, “only when the meaning of package is predictable will the parties concerned know when there is a need to place the risk of additional loss on one or the other accordingly.”
Aluminios Pozuelo, Ltd. v. S.S. Navigator, supra,
When a bill of lading specifies the number of containers but does not reveal the number of packages inside, the only certain figure known to both parties is the number of containers being shipped. In such event the carrier cannot be charged with knowledge of whether the container is filled with packages, with unpackaged goods, or with some combination. The carrier should not be expected to assume the risk inherent in such uncertainty, facing liability that might vary by orders of magnitude depending on the exact packaging of goods inside a sealed container, even though this information was not revealed to it by the bill of lading.
We accordingly hold that, when the bill of lading does not clearly, indicate an alternative number of packages, the container must be treated as a COGSA package if it is listed as a package on the bill of lading and if the parties have not specified that the shipment is one of
*1016
“goods not shipped in packages.” Maximum damages in such a situation then are $500 per container, irrespective of the contents. Although this rule could drastically reduce the damages available to shippers in some situations, it does not depart from the principle that the limited liability clause in COGSA was designed to “ ‘set a reasonable figure below which the carrier should not be permitted to limit his liability,’ ”
Mitsui, supra,
We recognize that the rule established by us today, which will henceforth limit a carrier’s liability under the same circumstances to $500 per container, resolves an uncertainty noted in earlier decisions (e.g., Mitsui and Smythgreyhound) and that, in view of this uncertainty, the partiеs might have reasonably believed that the description of the number of plants on the bills of lading was sufficient to bring the shipment within the Smythgreyhound rule to the effect that a container whose contents are disclosed (there, however, in terms of packages) should not itself be treated as a package. 11 Accordingly, the rule we announce will not be applied retroactively but prospectively to bills of lading prepared after the date of this decision.
With respect to the present case, since the plants described on the bills of lading clearly are not packages, they will be deemed to be “goods not shipped in packages” within the meaning of COGSA, which limits the carrier’s liability in such a case to $500 per “customary freight unit,” which is generally the unit on which the freight charge is based for the shipment at issue.
See General Motors Corp. v. Moore-McCormack Lines, Inc.,
We therefore remand the case to the district court to determine what the customary freight unit is for a shipment of plants of this type and to award Binladen *1017 damages in an amount up to $500 for each such unit. 12
Notes
. Binladen’s complaint invoked admiralty jurisdiction pursuant to Fed.R.Civ.P. 9(h). Jurisdiction over the defendants in the Southern District was based in part upon the presence of the ship within the district during the pendency of the litigation.
. The invoice/packing list for this Miami container also included 15 boxes of Canna Lilly bulbs, apparently unpotted. These were not mentioned on the bill of lading, and may not even have been included in the number of plants listed on the bill of lading, since the count of plants there was 15 less than the count on the invoice/packing list.
. A careful reading of Ramirez’s testimony along with the invoice/packing list from the nursery, reveals the following packing methods for the plants in the Houston container:
Number Item
481 Large barrel cacti
360 Small barrel cacti
250 E. lactea
490 Wooly Torch (880')
734 Mamillaria
175 Eagle Claw

342 A. trigorus

Thus, almost 2000 plants were individually tied, wrapped or boxed for travel, i.e., the Wooly Torch (490), the Mamillaria (734), the Eagle Claw (175), and the L. Marginatus (510), plus 25 boxes of orchids. As to more than 2000 other plants Ramirez indicated that they were tied or boxed, but did not indicate that they were individually packaged. Rather, in answer to a question, he stated that the number of plants per box varied with the size of the item. As to the remaining plants, no individual packaging was mentioned, and some of these (e.g., the large *1011 and small barrel cacti (841)) were clearly described as being simply stacked.
. This court has found that "containers are large metal boxes resembling truck trailers save for the absence of wheels, roughly 8' high, 8' wide and with lengths of up to 40' ..., capable of
*1013
carrying hundreds of packages in the normal sense of that term”; that containers “are typically supplied by the carrier, must be returned to the carrier by the consignee, and are used and reused hundreds of times"; that “[m]any ships ... are so constructed that shipments must be made in containers"; and that the shipper "normally ... [does not pay] for the weight of the ... container.”
Mitsui & Co., Ltd. v. American Export Lines, Inc., supra,
. The 1968 Brussels Protocol provides in pertinent part:
"Article 2
"(c) Where a container, pallet or similar article of transport is used to consolidate goods, the number of packages or units enumerated in the bill of lading as packed in such article of transport shall be deemed the number of packages or units for the purpose of this paragraph as far as these packages or units are concerned. Except as aforesaid such article of transport shall be cоnsidered the package or unit.”
. Binladen asks us to find that Nedlloyd waived any claim to the $500 per package limitation with regard to the shipment from Miami. The shipper bases this claim on several statements by Nedlloyd’s counsel at the start of the trial below, namely:
"Now, in the container that went out from Miami, they are actually potted. However, the ones that went out from Houston, although the witness in Houston stated that some of them were packaged, the plaintiffs witness was on hand in Jeddah.
"I have no problem with the Miami plants. They were plants. They were potted. But all of a sudden when you get the testimony of the plaintiff's witnessеs, there was absolutely no packaging in the containers from Houston____”
We decline to hold that Nedlloyd’s has waived limited liability as to the Miami shipment. The statements above are not unambiguous waivers of Nedlloyd’s contractual rights. They appear merely to reflect counsel’s acknowledgment that there was no factual dispute about the potting of the Miami plants and his recognition that there was a much stronger case to be made that many of the Houston plants were wholly untreated in *1014 preparation for shipment. At the very time of this conversation, the trial judge was on notice that Nedlloyd sought to aрply the liability limit to both the Miami and Houston shipments. Nedlloyd had explicitly made both arguments in a pretrial memorandum of law. Although Nedlloyd’s post-trial memorandum of law restated the argument for limited liability as to the Houston shipment but did not do so as to the Miami shipment, we do not view this omission as constituting a waiver of its statutory rights as incorporated into the shipping contract.
. We need not reach the question of which plants were prepared for transport in a way entitling them to be classified as packages, nor need we calculate exactly how many packages there were in the Houston container, given the various ways in which these plants were loaded. One may reasonably argue, for instance, that the plants in the Miami container may have been placed in pots to keep them alive, not for purposes of transport. Nor do we reach the question whether our conceptual definition of a package may impose limits on the types of items that parties may agree to treat as packages.
Cf. Bumble Bee Seafoods v. S.S. Kiku Maru,
. Although a Department of Agriculture phytosanitary certificate accompanying the Miami shipment listed the plants involved as "packed loose in pots within sea wheel trailers," this mention of packaging in a supplemental document of this nature, particularly one unrelated to the contract between the parties, cannot substitute for disclosure in the bill of lading. This document was apparently issued to the nursery that packed the plants into the Miami container and may not even have been read by the carrier. Unlike a bill of lading or a dock receipt,
cf. Standard Eléctrica,
S.A
v. Hamburg Sudamerikanische Dampfschifffahrts Geselbhaft, supra,
. This testimony in fact indicates that many plants in the Houston shipment were stacked without packaging. In this respect, we find clearly erroneous Judge Sofaer’s statement that "fe]ach plant ... was individually wrapped, potted or separated [and that] some were individually boxed” (emphasis added).
Although it was reasonable for Judge Sofaer to have rejected Elsazsser’s testimony that there were no packages at all, the Judge’s factual finding cannot be sustained by reference to the Ramirez deposition, the only other evidence concerning packaging within the Houston containеr. While Ramirez indicated that many of the plants were individually treated in the ways described by Judge Sofaer, he did not state that all of them were. Rather, the deposition makes clear that about 2000 were so treated, many others were tied, wrapped or boxed in an unspecified number, and the remainder, nearly 3000, were loosely packed, i.e., stacked logcabin style in piles, which might in turn be separated from each other by large cardboard dividers. See supra note 3.
. In Marcraft Clothes, Inc. v. M/V “Kurobe Marti,” 575 F.Supp. 239, 242-43 (S.D.N.Y.1983), on which Judge Sofaer relied, there was a clearer factual basis for holding each of 4,400 men’s suits to be a package, since each was individually wrapped in plastic. It is not clear from that decision what figure was entered in the "packages” column of the bill of lading, although the description of goods was apparently simply “4,400 Sets of Men’s Suits with Vest.” Id. at 242. If the entry in the "packages” column was "1 container,” (which we cannot determine from the decision), we would, absent further information, be inclined to disagree with the decision.
. Moreover, previous cases have held that the number entered in the packages column on the bill of lading is not itself determinative of the number of COGSA packages,
see, e.g., Solar Turbines Inc. v. S.S. "Al Shidadiah,"
. We find no merit in Binladen’s various claims that Nedlloyd should be deprived of the benefit of COGSA’s limited liability provision because of deficiencies in the bill of lading. Although Judge Sofaer did not reach this issue, we may rule on it here since it entails no fаctual findings outside the bill of lading, the terms of which are uncontested.
As Judge Sofaer recognized, the bill included a "U.S.A. CLAUSE” explicitly incorporating COGSA’s provisions in international voyages involving U.S. ports. That same clause also clearly contemplated that COGSA provisions would supersede any conflicting provisions in the bill of lading. As such, the other, lower, liability limits stated in the bill of lading are void, 46 U.S.C. §§ 1303(8), 1304(5);
David Crystal, Inc. v. Cunará Steam-Ship Co., Ltd.,
In view of the incorporation of COGSA and the existence of a space on the front of the bill of lading providing an opportunity for the declaration of excess value, and even the inclusion of other, albeit invalid, liability limits, the shipper here cannot be heard to claim that it lacked notice of the prospect that its recovery per package would be limited. This case is quite different from
General Electric Co. v. M. V. Lady Sophie,
