*221 OPINION OF THE COURT
FFE Transportation Services, Inc. (“FFE”) appeals from the judgment of the district court finding FFE liable to Beta Spawn, Inc. for the value of a shipment of mushroom spawn damaged during transport. FFE contends that the district court erred in finding (1) that Beta Spawn established a prima facie case under the Carmack Amendment to the Interstate Commerce Act, 49 U.S.C. § 11706; (2) that FFE’s tariff was not applicable to the shipment at issue; and (3) that FFE had agreed to maintain the temperature of its trailer at 34 degrees Fahrenheit 1 when transporting the spawn. Because we hold that the district court ruled correctly on all three issues, we affirm the judgment of the district court in favor of Beta Spawn on its claim for damages and against FFE on its counter claim to recover freight charges.
I. Background
Beta Spawn, a Pennsylvania corporation, supplies mushroom spawn to the mushroom industry. 2 At all times relevant to this case; Beta Spawn has been the exclusive distributor of a variety of spawn from Italy known as Italspawn. FFE is a common carrier hired by Beta Spawn to transport a shipment of Italspawn from Camar-illo, California to Beta Spawn’s facility in Pennsylvania.
According to the district court’s findings, mushroom spawn are “living, breathing” organisms that must be maintained at a temperature of approximately 36 degrees. Harry Testa, vice-president of Beta Spawn, testified that when spawn are exposed to higher temperatures, they begin to generate their own heat and to ferment. Spawn that have begun to- ferment are damaged and lose their viability. Once spawn are exposed to heat, attempts to re-cool the spawn will not be successful. Because spawn are fragile, they must breathe filtered air to avoid contamination. For that reason, spawn are packaged in clear, plastic bags with air filters on each bag. Condensation and yellow discoloration are signs of contaminated spawn. Damaged spawn also have a characteristic odor similar to that of vinegar.
In June 1997, Beta Spawn sold a truckload shipment of Italspawn (the “June Shipment”) to Peterson’s Ranch in Camar-illo, California . 3 Louis Peterson, an officer and director of Mushrooms, Etc. who received the shipment in California, testified that some of the boxes containing the spawn were torn and crushed at the time of arrival. Nevertheless, Peterson used spawn out of those damaged boxes to grow his first crop of mushrooms.
In September 1997, Peterson agreed to sell 16,000 units of the Italspawn back to Beta Spawn. These spawn had been stored for three months in a facility that was nearby, but not on, the farm premises and, according to Peterson, had remained refrigerated the entire time. Peterson testified that about three weeks after the spawn were shipped to Beta Spawn, he used a remaining portion of the June Shipment to grow a successful crop of mushrooms. That portion, however, was not stored in the same facility as the spawn sold to Beta Spawn.
*222 On behalf of Beta Spawn, Testa contacted Michael Conn of FFE to arrange for the shipment of the spawn from California to Beta Spawn’s facility in Pennsylvania. During their conversation, Testa and Conn verbally agreed that FFE would transport the spawn at a temperature of approximately 34 degrees. FFE had shipped spawn for Beta Spawn before and had always transported the spawn in a trailer maintained at 34 degrees.
On September 23, 1997, FFE entered into a bill of lading /contract of carriage with Mushrooms, Etc. of California for the transportation of the spawn to Pennsylvania. Mushrooms, Etc. requested that FFE provide it with less-than-truckload (“LTL”), “chilled” service. Beta Spawn, as consignee, agreed to pay FFE $2,685.36 for the shipment upon delivery. The bill of lading, prepared by Peterson Ranch, called for the transport of 16,000 units of spawn, packed in 400 boxes. The spawn were packed in clear plastic bags, three bags to a box, separated by cardboard dividers. Each cardboard box contained holes to permit air circulation. Peterson loaded the boxes into FFE’s refrigerated trailer on 10 pallets, 40 boxes to a pallet. Initially, the boxes were only secured to the pallets with clear plastic tape, but after the pallets were loaded onto the truck, William Forbito, the driver for FFE, shrink-wrapped the boxes to prevent their falling over during transport.
Forbito testified that when he picked up the spawn, he asked Peterson at what temperature he was to maintain the shipment. After Peterson responded “it goes chilled,” Forbito recorded the word “chill” on the bill of lading. Forbito also wrote the words “Temp. 34 degrees” on the bill of lading. At trial, Forbito explained that when he accepted the spawn in California, he took the temperature inside one of the boxes and found it to be 34 degrees.
Forbito also gave testimony regarding the condition of the boxes. He stated that the bottom “two layers” of boxes on every pallet “were bubbled out like they’re getting ready to bust open. The boxes was [sic] torn, they were crushed. And boxes open.” Forbito did not recall seeing any actual torn bags of spawn. After observing the damaged condition of the boxes, Forbito called his dispatcher and was told he could accept the load as long as he noted the damage on the bill of lading. Forbito then took exception to the condition of the entire load by writing “400” on the bill of lading.
Peterson testified that before the boxes were loaded onto FFE’s trailer, he opened one of the boxes and removed a bag of spawn for inspection. Peterson’s inspection of that bag consisted of a visual examination of the spawn’s coloring and a “sniff test” through the air filter on the bag for the odor of spawn fermentation. Based on these tests, Peterson determined that the spawn were in good condition because there was no yellowish tint and no odor. Peterson also looked through cracks of the torn boxes in order to see whether the bags in those boxes were ripped or open. Peterson testified that he saw no open bags.
Forbiio set the temperature of the trailer at 34 degrees and transported the shipment of spawn to Cudahy, California, where he loaded it onto another trailer that was also set at 34 degrees. A different driver then carried the shipment from California to Chicago. When the driver arrived in Chicago, approximately 100 boxes were crushed, but the temperature of the product was 34 degrees. In Chicago, boxes were removed from the truck, placed in a warehouse and later reloaded onto another truck bound for Pennsylvania. When the boxes left Chicago, approx *223 imately 20 of the boxes had “leaking product exposed.”
The shipment of spawn arrived at Beta Spawn’s facility in Pennsylvania on September 29, 1997. Testa, who was present when it arrived, described the shipment as a “big mess.” Specifically, he stated that “the bags were broke [sic] on quite a few boxes” and that “[t]here were [sic] a distinct odor that the spawn had started to soui'.” Testa checked the temperature of the spawn in approximately 10 boxes and found it to be between 48 and 58 degrees, which meant the spawn were no longer viable. Thus, Testa refused to accept delivery and notified FFE of Beta Spawn’s claim for damages.
Beta Spawn originally brought its claim against FFE for damage to its freight in the Court of Common Pleas of Delaware County, Pennsylvania. FFE removed the case to federal court and filed a counterclaim for its freight charges. The district court held a bench trial and granted judgment in favor of Beta Spawn. This appeal followed.
II. Standard of Review
This court has plenary review over the district court’s choice and interpretation of legal standards and its application of those standards to the facts of the case.
See Louis W. Epstein Family Partnership v. Kmart Corp.,
III. Discussion
A. Beta Spawn’s Prima Facie Case
To establish a prima facie case against a common carrier under the Car-mack Amendment to the Interstate Commerce Act, 49 U.S.C. § 11706,
4
a plaintiff must prove the following three elements: “(1) delivery of the goods to the initial carrier in good condition, (2) damage of the goods before delivery to their final destination, and (3) the amount of damages.”
Conair Corp. v. Old Dominion Freight Line, Inc.,
FFE’s main argument on appeal is that there was no competent evidence for the trial court to find that the spawn were delivered to FFE in good condition.
5
Specifically, FFE contends that under the law of this circuit, a shipper must prove by “direct evidence” that the merchandise was in good condition when tendered to the carrier if such merchandise was not visible or open to inspection at the time ,it was tendered. In support of its contention, FFE points to
Blue Bird Food Prods. Co. v. Baltimore & Ohio R.R. Co.,
*224
Blue Bird I
involved a shipper who relied solely upon a bill of lading, which represented that the carrier had received the shipment in “apparent good order,” in order to prove that the goods had been tendered in good condition.
See Blue Bird I,
Other courts, apparently focusing on the “direct evidence” requirement in the district court’s opinion, have cited
Blue Bird
for the proposition that where goods are not open and visible, a shipper may present only direct evidence, as opposed to circumstantial evidence, in order to establish the condition of its goods.
See, e.g., D.P. Apparel Corp. v. Roadway Express, Inc.,
In our view, however, the holding in Blue Bird, and even the “must establish direct evidence” language in the district court’s opinion, were simply directed at making shippers produce evidence, other than a clean bill of lading, to establish the condition of goods which were not open and visible for the carrier’s inspection. Accordingly, we reject the view that
Blue Bird
renders all circumstantial evidence irrelevant where the goods are not open and visible.

See Fine Foliage of Fla., Inc. v. Bowman Transp., Inc.,
Unlike the plaintiff in Blue Bird, Beta Spawn does not rely on the bill of lading as proof that it tendered the spawn to FFE in good condition. Instead, it mainly relies upon the testimony of Peterson, an officer and director of Mushrooms, Etc. Peterson testified that he successfully used a portion of the remaining Italspawn from the original June Shipment three weeks after the 16,000 units of spawn were shipped to Pennsylvania. Although we recognize that Peterson’s success is not conclusive proof as to the condition of the spawn at issue because the two portions of spawn were-kept in separate facilities, it does carry some weight in that all the spawn were stored under similar conditions. Peterson testified that the spawn — both on and off the farm — were refrigerated for the entire summer and never removed from the coolers. Further more, the cooler in which the spawn at issue were stored had a backup generator in case of power outage. Peterson visited the facilities where the spawn were stored every three to four days.
Peterson’s assertion that he maintained the spawn at a proper temperature during the summer was corroborated to some degree by Forbito’s testimony that when he received the spawn, the temperature inside the boxes was 34 degrees and by evidence that the temperature was at 34 degrees when the truck reached Chicago. As Tes-ta testified, once spawn is exposed to heat,' an attempt to re-cool the spawn will not be successful. Therefore, the fact that the boxes were at 34 degrees on the day they were tendered to FFE and on the day they reached Chicago tends to show that the spawn previously had been stored at the proper temperature and were in good condition when tendered to FFE.
*226 In addition, Peterson personally examined one of the bags of spawn before it was loaded onto FFE’s trailer. There was no “characteristic odor” of spawn fermentation nor did the bag have a yellowish tint which signifies damaged spawn. Peterson’s testimony that the bag contained good product was direct evidence only as to the condition of the spawn in that particular bag, but was circumstantial evidence of the spawn’s condition in the other bags, as the bags had all been stored and loaded together. FFE asserts that there was insufficient proof that the spawn were in good condition in light of the fact that Forbito took exception to all four hundred boxes on the bill of lading and testified that the bottom two layers of boxes on every pallet were crushed, torn or open. Peterson testified, however, that he looked through the cracks where the boxes were torn and did not see any ripped bags. In addition, Peterson testified that even if boxes were torn, it was still possible for the spawn to remain undamaged. In fact, when Peterson initially received the June Shipment from Beta Spawn, he successfully used spawn which had arrived in torn boxes to grow his first crop of mushrooms.
Thus, considering all the evidence presented to the district court, we hold that the court did not err in finding that Beta Spawn met its burden of proof that the spawn were delivered to FFE in good condition.
B. Applicability of FFE’s Tariff
Once a plaintiff has established a prima facie case under the Carmack Amendment, the burden shifts to the carrier to prove that it was free from negligence and that the damage was caused solely by “(a) the act of God; (b) the public enemy; (c) the act of the shipper himself; (d) public authority; (e) or the inherent vice or nature of the goods.”
Missouri Pacific R.R Co. v. Elmore & Stahl,
According to the record, FFE publishes a tariff that sets regulations for, inter alia, goods that are shipped with protective services. Section C of the tariff provides that an LTL shipment, shipped “cooler and so stated on the Bill of Lading by the shipper,” must be maintained at an air temperature of between 35 and 60 degrees. The temperature inside the boxes of spawn when they reached Pennsylvania was between 48 and 58 degrees. Thus, FFE argued at trial that it provided the requisite services in that the spawn arrived at a temperature that fell within the range prescribed by the tariff. The district court rejected this argument on the ground that FFE’s tariff did not apply to the shipment.
On appeal, FFE maintains that the inclusion of the word “chill” on the bill of lading meant that the parties agreed that the tariff provision regulating the transportation of LTL shipments of “cooler” commodities applied to the shipment of spawn. Yet, it is undisputed that the word “chill” is not found anywhere in FFE’s tariff. FFE asserts that the word “chill” is synonymous with “cooler” because FFE’s Claims Director, Raymond Flem- *227 ming testified that to him, the word “chill” meant the same as “cooler.” Although Flemming’s testimony may prove that Flemming understood the word “chill” to signify “cooler,” it does not necessarily establish Peterson’s understanding of the word. Accordingly, we hold that the district court did not err by finding that FFE’s tariff was not applicable to the shipment in this case.
C. Agreement to Maintain Temperature at SI Degrees
FFE also argues that it was clearly erroneous for the district court to find that FFE had agreed to maintain its trailer at 34 degrees while transporting Beta Spawn’s goods. The district court found that such agreement existed based on (1) prior business dealings between FFE and Beta Spawn involving the transport of spawn; (2) a “verbal agreement” between FFE and Beta Spawn that FFE would transport the spawn at 34 degrees; (3) the presence of the words “chill” and “34 degrees” noted on the bill of lading by Forbito; and (4) the temperature of FFE’s trailer when it arrived in Chicago. FFE objects to this reliance on extrinsic evidence by the district court because the bill of lading, as prepared by Peterson, did not contain an agreement to maintain the trailer at 34 degrees.
Under Pennsylvania law, “[w]here the contract or agreement is unambiguous, parole evidence of prior inconsistent terms or negotiations is inadmissible to demonstrate intent of the parties.”
Harley-Davidson, Inc. v. Morris,
A contract is ambiguous if “it is reasonably or fairly susceptible of different constructions and is capable of being understood in more senses than one and is obscure in meaning through indefiniteness of expression or has a double meaning.”
State Highway and Bridge Auth. v. EJ Albrecht Co.,
Because we perceive ambiguity in the words “chill” and “Temp. 34 degrees,” we conclude that the district court properly considered extrinsic evidence in determining the existence of an agreement to maintain the trailer' at 34 degrees. Accordingly, we agree with its findings that FFE did not provide the requisite services under the agreement and that FFE is not entitled to recover shipping charges.
IV. Conclusion
Based on the foregoing reasons, we affirm the judgment of the district court in favor of Beta Spawn on its claim for damages and against FFE on its counterclaim to recover freight charges.
AFFIRMED.

No. 99-0815,
.Peterson’s Ranch, also known By the name "Mushrooms, ELc.,’’ is a mushroom farm.
. The district court found that this action was controlled by the Carmack Amendment. The Carmack Amendment imposes liability on a common carrier for the actual loss or injury to goods in an interstate commerce shipment. See 49 U.S.C. § 11706.
. FFE does not contest the district court's findings as to the last two elements.
. We explicitly stated in
Blue Bird II,
"[t]he issue presented is whether the introduction of a bill of lading with the notation 'Received ... the property described below, in apparent good order ... ’ is sufficient to establish the good condition of the lading at the time it was delivered by the shipper to the carrier."
Blue Bird II,
. It is logical that courts would prohibit a shipper's reliance on a clean bill of lading alone where goods are not open and visible, because the condition of such goods are unknown to the carrier.
See Pillsbury v. Illinois Cent Gulf R.R.,
. The district court made no finding as to whether the shipment of spawn was open and visible. FFE asserts in its brief that the shipment was not open to inspection because the spawn were contained in closed boxes and because FFE's policy prohibited drivers from opening closed boxes. We do not agree that such evidence necessarily establishes that the spawn were not visible and open to inspection. In contrast to the goods in Blue Bird, the spawn here were not in a sealed trailer.
See Blue Bird II,
. As the parties do not dispute that Pennsylvania law governs the interpretation of the agreement, we will apply Pennsylvania law.
. FFE argues that we should not look to the words "chill" and "Temp. 34 degrees” on the bill of lading because, as an independent contractor, Forbito had no authority to enter into agreements to bind FFE. The record reflects, however, that Forbito drove exclusively for FFE, was given authority by FFE to transport the shipment of spawn, specifically asked Peterson at what temperature the spawn was to be shipped, and was the only representative of FFE to sign the bill of lading. Thus, even assuming Forbito had no actual authority to add terms to the bill of lading regarding the proper temperature of the shipment, we believe there is sufficient evidence that he had apparent authority to do so.
See Leidigh v. Reading Plaza Gen’l, Inc.,
. Forbito testified that he took the temperature of some of the boxes at the time they were loaded onto his truck in California and found it to be 34 degrees. But, when asked on cross-examination, "And when you write on here, chill, temperature 34, that's to keep the product at 34 degrees?,” Forbito replied, "At 34 degrees, right.”
