When sourcing aluminum carry-on luggage for a brand, compare complete outside dimensions, empty weight and the required configuration together. Models described as “20-inch” do not necessarily meet the same sourcing brief.
This guide explains how to turn market requirements into model-selection criteria, compare existing cases and decide whether a mismatch calls for another model or a design review.
Define the product brief before comparing factory models
When sourcing aluminum carry-on luggage for a brand or wholesale range, start with the requirements the product must meet. Set out the target market, relevant routes, maximum overall dimensions, empty-weight target and features that must stay. A request for a “20-inch aluminum carry-on” does not give a factory enough information to identify the right model.
For a range covering several markets, first compare their dimensional requirements. If a common specification rules out the intended case design, decide whether separate size versions make more sense. Resolve that choice before committing to a silhouette and discovering during sampling that its size and weight cannot meet the brief together.
Airline rules provide inputs for that brief. For example, the general Emirates Economy allowance is 55 × 38 × 22 cm and 7 kg, according to its official page checked November 4, 2026, with conditions for particular journeys. Select the relevant reference for your market rather than presenting one airline’s limits as a universal claim for the range.
Separate requirements that must stay from preferences you can reconsider. Full-aluminum construction, the dimensional envelope and a particular storage function may be essential, while the handle appearance is negotiable. Screen models in that order. If dimensions, weight, construction and interior are all fixed and no model meets them, resolve that conflict first. Customization alone does not establish that the combination is feasible.
The outcome should be a usable sourcing brief: maximum complete-case dimensions, target empty weight, whether full-aluminum construction is essential, and which interior and exterior features must be retained.
Compare complete-case dimensions across suppliers
Two catalogs can describe different products as “20-inch.” Compare the outside dimensions of the assembled case, including wheels, handles and hardware. Shell height, body dimensions and internal dimensions belong in separate fields. Mixing them can put an unsuitable model on the shortlist.
Each candidate should have a dimensioned drawing or image identifying height, width and depth, with an explicit statement covering wheels, stowed handles, feet and projecting hardware. If the specification gives only body dimensions, obtain the overall measurements before deciding whether it fits the brief.
| Information supplied | What is missing | Decision it supports |
|---|---|---|
| “20-inch” only | Complete outside dimensions for that size version. | Whether the actual model meets the brief. |
| Body dimensions only | Maximum dimensions after external components are installed. | Whether excess size comes from the body or external fittings. |
| Nominal size equals the project limit | Maximum finished dimensions allowed by the drawing. | Whether the design target must decrease or a smaller model is needed. |
If the brief limits depth to 22 cm and a complete case measures 23 cm, spare height or width does not make it a dimensional match. Establish whether that extra depth comes from the shell, frame or projecting fittings before reviewing a modification.
Will a smaller outside envelope still provide the interior space the range needs? Reducing the specified depth by 1 cm does not establish unchanged capacity or interior fit. Review clear internal space together with the frame, lining and intended fittings. If the brief requires a particular organizer module, compare its outside dimensions with the available space.
For a geometric example, the enclosing rectangular volume of 55 × 36 × 23 cm is 45.54 liters. At 22 cm depth it becomes 43.56 liters, a reduction of 1.98 liters. These are outside bounding volumes, not usable packing capacities. Rounded corners, the frame, trolley system and interior still need to be accounted for using the actual design and finished case. The sourcing decision is whether to accept the space change or compare another case design.
For a design close to the limit, account for permitted finished-size variation. There is no universal “allow 1 cm” rule for every project. Use the model’s drawing and measured dimensions rather than changing the nominal figure in a catalog.
Turn empty weight into a sourcing requirement
Empty weight needs to be judged against the intended use of an aluminum carry-on. A case can match the desired appearance and dimensions yet leave too little weight for contents to suit the range.
Suppose a project uses a 7 kg packed-bag limit and aims to leave 4 kg for contents. The empty-case target is no more than 3 kg. A 4 kg candidate has a 1 kg shortfall. The next question is whether another model or a proposed modification can resolve that shortfall, rather than asking for the case to be “as light as possible.” These figures illustrate a sourcing decision; they are not Aluvox model specifications.
Compare weights for the complete configuration intended for sale. Record whether dividers, straps and supplied interior accessories are included, and exclude the shipping carton and protective packaging from empty-case weight. A stripped interior is not directly comparable with another model’s complete configuration.
Compare layouts before deciding what to remove. A request for a lighter interior can remove the storage feature the brand intended to retain. Screen layout alternatives against the shortlisted case’s opening and interior space, then compare their complete configured weights. The following are directions to assess during model selection.
| Candidate layout | Arrangement | Sourcing decision |
|---|---|---|
| Simple clothing layout | A zippered divider on one side and retaining straps on the other, with necessary small-item pockets on the divider. | A candidate for a range prioritizing open main-compartment space. Choose pockets with a defined use, then check the complete interior weight. |
| Business organization | A padded device sleeve, flat document pocket and accessory pockets at suitable locations. | Check actual device dimensions and access order, then assess the remaining main-compartment space. Access to a laptop while the main case stays closed also involves the case opening; an inside sleeve alone cannot provide it. |
| Removable organization | Retain the main compartment and straps, with removable accessory, shoe or laundry pouches; identify which are supplied with the case. | Decide whether a pouch needs to be carried separately, then compare fit, attachment and complete configured weight. The case weighed without supplied pouches is not the weight of the complete supply configuration. |
Individual compartments or a pouch taken out as one unit? For defined locations for cables and small accessories, review pockets attached to the divider. For removing the accessories together, review a separate pouch. Compare both against the same intended contents; a version holding fewer items or supplied with fewer accessories does not establish a like-for-like weight or price advantage. Retaining straps are not automatically a compression-panel system, and an ordinary separating pouch is not a verified leakproof bag. Specify any required compression or moisture-separation function separately.
Before comparing supplier quotations, also check that the weights refer to the same size and interior requirements. If a lower figure comes from different construction or fewer accessories, the buyer needs to decide whether that tradeoff is acceptable.
Ask a weight-reduction proposal to show the saving from each actual change. For the hypothetical 4 kg model and 3 kg target, suppose an interior change saves 200 g and other fittings save 100 g. The total saving is 300 g: the revised case is still 3.7 kg, leaving 700 g unresolved. A feasible local saving does not establish that the complete case meets its target. Identify which functions remain or disappear so the buyer can assess the tradeoff.
If the proposal also changes shell or frame specifications, reassess the relevant structural and performance requirements. Do not assume lower weight with identical performance without evidence. The buyer can retain the construction and revise the empty-weight target, compare other models or pursue a structural development review. Those choices describe different products and should not be combined into one specification.
Keep overall dimensions, empty weight, material construction and interior version together in the model comparison. Capacity in liters helps describe space but cannot replace those sourcing requirements.
Decide whether to select another model or review a design change
Compare the shortfall and the parts involved before reviewing a modification. A model close to the target, with excess size concentrated in external fittings, may justify a component review. If the shell or frame itself is too large, compare other existing models first. This helps establish whether a modification is worth pursuing before defining development work.
| Mismatch | Check first | Sourcing decision |
|---|---|---|
| Excess overall height | Body height, installed wheel-assembly height and stowed top-handle projection. | If the body fits, review the reduction available from compatible fittings. If the body is too tall, compare shorter models first. |
| Excess width | Whether the widest point is a handle, foot, shell or frame. | Review more compact fittings where they cause the excess. If the body is too wide, compare narrower models. |
| Excess body depth | Complete closed depth across shell, frame and hardware. | Compare shallower cases first. If the silhouette must stay, review the body changes required. |
| Size fits but empty weight is too high | Required weight reduction, selected interior and actual weights of parts proposed for change. | Compare the proposed saving with the shortfall. If it remains unresolved, reconsider the model, construction or interior. |
A possible component swap is not yet an adoptable solution. Check whether the proposed part fits the model, what it changes after installation and whether the required functions remain. A smaller wheel does not establish an equal reduction in overall height. Removing organizers cannot be promised to resolve a 1 kg shortfall without their actual weights.
Review fittings in their installed state. For wheels, check mounting position, installed height and clearance from the case during rotation. For handles, check stowed projection and operating space. Recessing a wheel further or using a closer-fitting handle is a proposal to assess, not a confirmed solution for every model. Where the change reaches the shell, frame or mounting position, treat it as a structural review rather than an established direct replacement.
If the brief must retain a full-aluminum shell, the current silhouette and the complete interior, an available model may not reach the weight target. Make that conflict explicit so the buyer can choose another model, revise the target or review another construction before confirming the selection.
If alternatives include a PC shell with an aluminum frame, revise the material description and product positioning accordingly. Our aluminum versus polycarbonate guide covers that material decision.
Keep the selected model, measurements and configuration together
Identify the SKU, size and configuration version selected for further development. That record makes it possible to assess whether a later wheel, handle or interior change affects the original selection.
Brief: maximum overall depth 22 cm, maximum empty weight 3 kg, with the specified divider and straps retained.
Candidate A: overall depth 23 cm and empty weight 4 kg, including the selected interior. All figures are hypothetical.
Decision: depth exceeds the target by 1 cm and empty weight by 1 kg. Do not confirm A yet. Compare existing models meeting both targets first. If A is retained, the proposed change must explain how each shortfall will be resolved.
After a modification, update the selection record with the revised complete-case dimensions, empty weight and actual configuration. Wheel and handle changes call for renewed checks of outside dimensions, installation and operation. Interior changes call for weighing the complete revised configuration. Once size and weight meet the brief, continue with the relevant sample review.
What supports moving the model forward? Mark each requirement as met by the current configuration, awaiting confirmation after a change, or not met. A model meets the sourcing brief only when complete-case dimensions and configured weight have corresponding results and the required functions remain. A model awaiting changes may still be worth developing, but its status should stay distinct from a model already meeting the brief.
The selection record should explain why this model suits the sourcing project, which requirements it meets and which changes remain outstanding. It does not replace sample approval or durability results.
Send Aluvox the product targets and shortlisted models
Shortlist candidates from our aluminum luggage range, then provide the target market, maximum overall dimensions, empty-weight target and interior and exterior requirements that must stay. Those details allow a comparison around specific models rather than repeated requests for a “20-inch case.”
For a candidate that meets the brief, continue with project review. Where it falls short, identify the difference before discussing another model or a modification. For logo, color and range development, see our private label service.
