Appeal by the Government from a judgment of the United States Court of International Trade, 1 C.I.T. 119, 511 F. Supp. *35804 (1981), sustaining a protest by Standard Surplus Sales, Inc. (Standard) against classification of various styles of imported bags as “luggage” under item 706.24, Tariff Schedules of the United States (TSUS). The Court of International Trade held the goods properly classifiable under item 735.20, TSUS, as “sports equipment.” We reverse.1

THE IMPORTED MERCHANDISE
Standard introduced illustrative exhibits: (1) Ridge Runner Nylon Bag; (2) Nylon Trail King Bag; (3) Nylon Crestline Bag; (4) Pathfinder Nylon Bag; (5) Nylon Cougar (or Ecology) Bag; (6) Nylon Overnighter Bag; (7) Nylon Mini-Rucksack; (8) Nylon Hiker Rucksack; (9) Fanny Bag; (10) Nylon Stuff Bag; and (11) Nylon Belt Pouch.
Exhibits 1 through 5 are bags designed for attachment to a rigid or semi-rigid aluminum framework. The assemblage of the bag on a frame is a type of backpack called a frame pack.
Exhibits 6, 7 and 8 are frameless, smaller packs, called soft packs, and are backpacks complete in themselves. Each of these three has adjustable shoulder straps. Exhibit 8 has a nylon handle at the top.
Exhibit 9 is an oblong zippered bag sewn into an adjustable waist belt and worn on the user’s lower backside. Exhibit 10 is a long *37cylindrical bag, closed at one end by a drawstring. Exhibit 11 is a small nylon zippered pouch attachable to the user’s belt with metal clips.
court of international trade
The Court of International Trade found the importer’s exhibits to be "markedly different from articles known as luggage, which are defined in the Tariff Schedules in Schedule 7, Part 1, Subpart D, headnote 2(a).” 2 The court said that none of "exhibits are designed to, or would be convenient to, carry by hand.” Noting that exhibits 1-5 were designed to be attached to a frame, the court said "it would be contrary to the weight of the evidence to consider them alone, or in conjunction with the frame, as pieces of luggage.”
The court found that chief use of the imported merchandise is in the sport of backpacking — “a use which is not the sort of ‘travel’ for which the luggage provision of the Tariff Schedules was intended. Use of these packs is use of the essential instruments with which the sport is practiced.”
ISSUE
The issue is whether the imported nylon bags are properly classifiable as sports equipment or as luggage.
OPINION
Standard characterizes as a finding of fact the trial court’s determination that the exhibits are “markedly different” from the listed luggage exemplars. The common meaning of a tariff term is, however, a question of law. Marvel v. Merritt, 116 U.S. 11, 12 (1885); United States v. National Carloading Corf., 48 CCPA 70, 71, C.A.D. 767 (1961); United States v. Florea & Co., Inc., 25 CCPA 292, 296, T.D. 49396 (1938). The scope of review is not, therefore, controlled by the clearly erroneous standard of 28 U.S.C. 2601(c) (1976), as amended by the Customs Courts Act of 1980, Pub. L. No. 96-417, § 403(d), 94 Stat. 1741.
In interpreting a tariff term, a court may:
rely upon its own understanding of the word or term used, and it may assist its own understanding by reference to the works of *38standard lexicographers, scientific authorities, the testimony of witnesses, or by such other means as may be available. If testimony be offered upon the common meaning of a statutory word or term such testimony is advisory only and has no binding effect on the court.
United States v. John B. Stetson Co., 21 CCPA 3 at 9, T.D. 46319 (1933); see Savannah Sugar Refining Corp. v. United States, 20 CCPA 272, 278, T.D. 46061 (1932), cert, denied, 288 U.S. 615 (1933). When Congress has used a term in its everyday sense, dictionary citations are most significant. Floral Arts Studio v. United States, 46 CCPA 21, 26, C.A.D. 690 (1958).
The testimony establishes, and the Court of International Trade agreed, that exhibits 1-8 are generically known as “backpacks.” A survey of eleven authoritative dictionaries published between 1888 and 1969 reveals that the noun “backpack” is absent from all of them. The first reference to “backpack” appears to have occurred in the 1963 edition of The World Book Encyclopedia Dictionary where it is defined as a transitive verb “to carry in or as a pack on one’s back.” “Knapsack,” on the other hand, was not only a commonly recognized term in 1962 when the present Tariff Schedules were drafted but became one of the luggage exemplars in headnote 2(a).3
The role of “knapsack” as a precursor of the term “backpack” was indicated at trial:
Q: “And how long have you been a backpacker?”
A: “Since I was about six years old. I don’t want to count that far.”
Trial Judge: “They used to call them a knapsacker then.”
Tariff terms are written for the future as well as the present, United States v. L. A. Salomon & Bro., 22 CCPA 490, 495, T.D. 47483 (1935), meaning that tariff terms can be expected to encompass merchandise not known to commerce at the time of their enactment, provided the new article possesses an essential resemblance to the one named in the statute. Smillie & Co. v. United States, 12 Ct. Cust. Appls. 365, 367, T.D. 40520 (1924).
Standard’s attempt to distinguish the imported backpacks from “knapsacks,” by comparing them to a sample knapsack (Exhibit 12) must fail. Standard's witnesses testified that Exhibit 12: (1) is made of heavy duck material; (2) has narrow shoulder straps that rope up during use, reducing their load spreading capacity; and (3) rests directly on the user’s back, causing perspiration and discomfort. Though Exhibit 12 is made of heavy duck, “knapsacks” can, like the imported bags, be made of lightweight nylon. Webster’s New Collegiate *39 Dictionary (1977). Moreover, under item 706.24, TSUS, the material is not critical. Articles may be “[o]f cotton . . . [or] [o]f other textile materials.” The Tariff Classification Study (1960), in discussing Schedule 7, Part 1, Subpart D, states at page 47, “This subpart would cover all luggage, handbags, and flat goods of whatever material composed. . . .” That Exhibit 12 employed shoulder straps of a particular design is of no probative value in determining whether the imported merchandise was properly classified. Equally nonprobative is the body-contact occurring in the use of knapsacks. Exhibits 1-5 must be considered in the condition imported, that is, without the contact-preventing frames. Exhibits 6-8, the soft packs, like Exhibit 12, are worn in contact with the body.
The substantial identity of backpacks and knapsacks is reflected in dictionary definitions:
Backpack—“a pack or knapsack earned on the back, as by campers.” Funk & Wagnalls Standard® Dictionary of the English Language (International Edition) (1973);
Backpack—“a load carried on the back (as by knapsack) * * * Webster's Third International Dictionary (1966);
Backpack (noun)—“a camping pack (as of canvas or nylon) supported by a usu. aluminum frame and carried on the back * * * .”; (verb transitive) “to carry (food or equipment) on the back esp. in hiking”; and
Knapsack—“a bag (as of canvas or nylon) strapped on the back and used (as on a hike) for carrying supplies or personal belongings.” Webster's New Collegiate Dictionary (1977).
That inclusion of knapsacks as luggage exemplars in the 1962 Tariff Schedules was intended to have encompassed backpacks is consistent with the 1977 Summary of Trade and Tariff Information (USITC Series No. 841, Control No. 7-1-1, November, 1977 on luggage) ,4 This Summary states at page 2:
[L]uggage can be separated into a number of broad categories * * * (1) traditional hand luggage5 * * * (4) sports and recreational bags, such as golf bags, gun cases, fishing-rod cases, pool-cue cases, bowling bags, tennis bags * * * backpacks j *40knapsacks, haversacks, duffle-bags, binocular cases, and camera cases * * * . [Emphasis supplied.]
Exhibit 7 is labeled “Nylon Mini-Rucksack.” One of Standard’s witnesses identified Exhibit 8 as a “Nylon Hiker Rucksack.” Dictionary definitions equate rucksacks and knapsacks:
Rucksack — “knapsack” Webster’s Seventh, New Collegiate Dictionary (1963); Webster’s New Collegiate Dictionary (1977);
Rucksack — “a type of knapsack carried by hikers, bicyclists, etc. [G: lit., back sack] The Random House Dictionary of the English Language _ (unabridged) (1967);
_ Rucksack — “a kind of knapsack strapped over the shoulders” Webster’s New World Dictionary (College Edition) (1962); and
Rucksack — “knapsack carried by hikers” The American College Dictionary (1962).
Backpacks and rucksacks are within the common meaning of the 1962 tariff term “knapsack”. As “knapsacks” are an exemplar of “luggage” under headnote 2(a), we hold that Exhibits 1-8 were properly classified under item 706.24, TSUS, by the Customs Service.
The trial judge’s finding that the chief use of the imported merchandise is in the sport of backpacking was clearly correct on this record. The accompanying characterization of that use as “not the sort of 'travel’ for which the luggage provision * * * was intended” was in error. The term “luggage” in headnote 2(a)(i) covers “travel goods, such as * * * knapsacks * * * and like articles designed to contain clothing or other personal effects during travel.” “Knap-sacking” is defined as “travelling with a knapsack” in Webster’s New International Dictionary of the English Language (1949). Thus the sort of “travel” for which the luggage provision was intended includes knapsacking and its equivalent backpacking. It can hardly be said that one hiker wearing a knapsack was engaged in “travel” within the statute and that a companion wearing a backpack was not. Nor can it be said that the former was carrying luggage and the latter was not. We are impelled to the conclusion that backpacking is also “travel” within the meaning intended in headnote 2(a)(i).
Exhibits 9, 10 and 11 were specifically designed for backpacking and were also apparently unknown when the 1962 Tariff Schedules were drafted. To be classified under a specific tariff provision, it “would be sufficient if the new article possessed an essential resemblance to the former [exemplars] in those particulars which the statute established as the criteria of the classification.” Klipstein v. United States, 4 Ct. Cust. Appls. 510, 514, T.D. 33936 (1913); see Smillie & Co. v. United States, supra. The criteria for classification under item 706.24, TSUS is established in its accompanying headnote *412(a)(i), i.e., the imported bags must be “like” 6 exemplars and “designed to contain clothing or other personal effects during travel.” Exhibits 9, 10 and 11 possess characteristics common to knapsacks, duffle bags and satchels, respectively, and are used for the purpose set forth in headnote 2(a)(i). Exhibits 9, 10 and 11 were therefore properly classified under item 706.24, TSUS.
Standard argues that because backpacking is a sport, Newman Importing Co., Inc. v. United States, 76 Cust. Ct. 143, C.D. 4648 (1976), equipment used in that sport should be classified as sport equipment under item 735.20, TSUS. However, its accompanying headnote. specifically excludes “luggage” from 735.20 coverage. The exclusionary headnote directs a classifier to part ID, where headnote 2(a)(i) includes “knapsacks” and headnote 2(a)(ii) includes “golf bags” and “gun cases.” The 1977 Summary of Trade and Tariff Information, supra, lists “sports and recreational bags” as a broad category of luggage. Headnote 1 (vii), the headnote 2(a) exemplars, and the Summary thus indicate that although the imported bags are used in the sport of backpacking, they are nonetheless properly classified as luggage.
Responding to the Government’s position that exhibits 1-5 are unassembled or unfinished luggage, Standard assumes, arguendo that those exhibits are “luggage” when attached to frames. Standard then argues that, because they are imported without frames, they are at that time parts of luggage. Thus, argues Standard, they are not classifiable under item 706.24, TSUS, which does not provide for parts of luggage, but are classifiable under item 735.20, TSUS, which provides for sport equipment “and parts thereof.” The argument is without merit.
In view of headnote l(vii), supra, the classifications for luggage under item 706.24, TSUS, and for sport equipment under item 735.20, TSUS, are mutually exclusive. Exhibits 1-5 cannot be both parts of luggage and parts of sport equipment. As above indicated, Standard has failed to carry its burden of proving the correctness of its claimed classification as sport equipment under item 735.20. The importer *42cannot, therefore, establish its asserted classification for exhibits 1-5 as parts of sport equipment. Hence, exhibits 1-5 are presumed to have been properly classified as luggage.7 See United States v. A. Johnson & Co., Inc., 66 CCPA 35, C.A.D. 1218, 588 F. 2d 297 (1978); United States v. New York Merchandise Co., Inc., 58 CCPA 53, C.A.D. 1004, 435 F. 2d 1315 (1970); United States v. National Starch Products, Inc., 50 CCPA 1, C.A.D. 809, 318 F. 2d 737 (1962), cert. denied, 373 U.S. 923 (1963).
We conclude that the imported merchandise was properly classified under item 706.24, TSUS. The judgment of the Court of International Trade must therefore be reversed.
