WEIMI / PHYSICAL SET · COMPONENT · ASSORTMENT GTIN
Define the physical assortment, its component trade items and the packaging hierarchy before accepting a substitution.
One combined physical item.
Separate identities for the defined components.
A hypothetical operator buys a fixed gift bundle for a vending assortment. The supplier replaces one included item while retaining the familiar bundle name. The refill team now faces two physical compositions and needs to know which assortment record describes each pack.
GS1’s predefined-assortment rule defines a fixed composition of two or more trade items combined and sold together as one physical trade item. A change, addition or replacement of an included trade item requires a new GTIN. The source also distinguishes the individual components’ identifiers from the assortment’s identifier.
This article addresses the physical combined item and its component record. It is separate from an on-screen discount, a printed-price change or a camera recognising several loose products. No real supplier bundle or vending deployment was tested.
Ask for the defined physical composition, the assortment GTIN and the separate component GTINs before accepting a substitution. When the fixed bundle changes, request the supplier’s new assortment identifier and the updated existing packaging hierarchy.
GS1 places the change at the retail consumer trade item or base unit and requires a unique GTIN at every existing packaging level above it. Receiving may use a case record while the machine presents the physical bundle, so confirm both relationships.
Establish the physical scope first. A dashboard offering two loose products at a discount does not itself prove a predefined physical assortment exists. Have the supplier and responsible data parties explain the actual trade item rather than classify it from a promotion name.
| Supplier statement | Identity question | Acceptance boundary |
|---|---|---|
| Fixed physical set | Which items form the one combined trade item? | Distinct from loose-product promotion |
| Component replaced | What changed in the defined composition? | New assortment GTIN under the rule |
| Component identifier supplied | Which individual item does it identify? | Separate from the assortment identifier |
| Case identifier supplied | Which combined retail units does it contain? | Existing hierarchy must be reconciled |
| Same outer set name | Which old or revised record applies? | Name alone does not settle identity |
The evidence questions identify the actual combined item. They do not approve its contents, decide every other GTIN rule or establish that a machine can dispense it.
Use this brief for operators buying fixed physical snack sets, personal-care combinations or other prepacked assortments sold as one retail item. It is useful for distributors handling substitutions and warehouse teams receiving old and revised compositions.
Confirm whether the supplier sells a combined physical trade item and whether its included items are explicitly defined. A general “mixed selection” description leaves the identification relationship uncertain.
For a software promotion involving separately selected products, first map the actual process. This article does not say that every price bundle is a predefined physical assortment. Nor does it establish food labelling, product-safety or local regulatory acceptance for the contents of a set.
WEIMI public hardware evidence was reviewed on 10 October 2026. GS1’s predefined-assortment rule was read on 11 October 2026. We use public descriptions and proposed acceptance questions. No physical bundle was dispensed, recognised or mapped through a vending host system during this research.
Begin with the supplier-defined composition. Retain the assortment identifier, each explicitly defined component identifier and the existing higher-level packaging relationships. Compare the old and revised records to identify the substitution instead of relying on the unchanged set name.
Ask the provider to demonstrate receiving and refill with approved test records. Record which identifier selects the assortment and how a case maps to its combined retail units. Scanning a component should not be mistaken for evidence that the whole assortment record was selected.
Evaluate hardware suitability separately with the physical pack. Request the agreed dispensing or recognition demonstration for its actual dimensions, presentation and packaging. A consistent data file does not prove the set fits a channel or is recognised by an AI retail workflow.
Fixed physical composition: establish what is combined and sold as one physical item. The source’s definition includes two or more trade items in a fixed composition. Do not replace that evidence with a broad marketing description.
Component separation: GS1 says individual trade items are explicitly defined by trading partners and have unique GTINs separate from the assortment. Keep those identities distinct in the supplier’s record.
Substitution trigger: a change, addition or replacement matters under the rule. Replacing one included product is not automatically neutral because the outer name stays the same.
Hierarchy: request the assortment and every affected existing level above it together. A receiving team working with cases needs the corresponding relationships, not only a new retail number.
Old and new stock: retain the earlier composition record while old bundles remain in the operation. Define the transition so the team can explain which physical set was loaded.
Pack acceptance: a new component may alter the physical package, but no effect should be assumed. Demonstrate the actual revised pack through the quoted mechanism or recognition workflow.
Content claims: a component substitution can raise separate information questions. Have the responsible reviewers assess the actual labels and product requirements; GTIN management alone does not approve the contents.
Applicable requirements: GS1 notes that local, national or regional regulations can require more frequent changes and take precedence. This guide does not replace that review or assign a regulatory outcome.
These three real WEIMI listings form a public-description equipment shortlist. “Best” means candidates worth evaluating for the intended purchase, not tested physical-bundle support. Compatibility and assortment identification are unverified for all three.
HARDWARE CANDIDATE 1 / ACTUAL SET TO VALIDATE
The single-door AI vision fridge listing describes camera-based packaged-goods checkout, five shelf levels with five baskets and top screen or lightbox options. Confirm cooling. It does not prepare juice. Its public description does not establish acceptance of a particular combined set; request actual pack-recognition evidence independently of the supplier’s assortment identifiers.
HARDWARE CANDIDATE 2 / ACTUAL SET TO VALIDATE
The WM22 page describes a 21.5-inch touchscreen, inventory-related management and cooling, with optional spiral, conveyor, direct-push or hanging mechanisms. Confirm the ordered mechanism. Conflicting generic capacity and energy figures are excluded. A physical set needs its own fit and dispensing review, while the application must select the supplier-confirmed assortment record.
HARDWARE CANDIDATE 3 / ACTUAL SET TO VALIDATE
The dual-cabinet listing shows a main display and an additional visible spiral stock area. Confirm the quoted arrangement. Shared software, independent cooling, a second screen and capacity are not established. Additional stock space does not prove that a combined pack fits or that component and assortment records are linked correctly.
| Public retail candidate | Confirmed description | Combined-pack check |
|---|---|---|
| Single-Door AI Vision Smart Fridge for Packaged Drinks | Camera-based packaged-goods checkout | Actual set packaging and recognition acceptance |
| WM22 Snacks and Drinks Vending Machine | Touchscreen and selectable dispensing mechanisms | Actual pack fit and selected assortment record |
| Two Cabinets, More Choice: Snack & Drink Vending Station | Main display plus visible spiral stock area | Pack handling and hierarchy for ordered arrangement |
Keep the combined pack’s identity and its hardware fit in separate evidence records. A host selecting the right assortment can coexist with unresolved dispensing or recognition acceptance.
Hypothetical physical-assortment review budget, not a supplier quotation or predicted return. Assume six hours to reconcile composition and hierarchy records at USD 70/hour, seven hours for controlled receiving and hardware checks at USD 70/hour and four hours to document the transition at USD 70/hour.
| Assumed task | Calculation | Illustrative cost |
|---|---|---|
| Composition and hierarchy review | 6 × USD 70 | USD 420 |
| Controlled host and hardware checks | 7 × USD 70 | USD 490 |
| Transition documentation | 4 × USD 70 | USD 280 |
| Total | 420 + 490 + 280 | USD 1,190 |
The invented USD 1,190 total excludes samples, barcode services, software changes, packaging development, travel and repeated demonstrations. Obtain actual quotes after defining the set and required acceptance scope.
At an assumed USD 14 contribution per sale, USD 1,190 represents 85 sales of contribution before other costs. This illustrates budget scale, not demand or payback. No reduced stock error, increased order value or customer saving was measured.
For a component replacement inside a fixed physical bundle, compare the supplier-confirmed old and new compositions and assortment identifiers. Retain the component identities rather than treat the bundle name as the record.
For an additional component, ask how the combined item and higher-level packaging records change. Do not assume the extra item can be represented only by an informal note in the refill schedule.
For old and revised bundles received together, define which case records lead to which assortment composition. Keep the transition visible to the warehouse and route team.
For an on-screen promotion involving loose items, establish the process separately before applying this physical-assortment rule. A purchasing checklist should not transform a software discount into a fictitious prepacked trade item.
A supplier change notice can specify the affected assortment, component substitution and new identifiers. The buyer can request missing hierarchy information before dispatch.
A commissioning exercise can use approved old and new records to demonstrate receiving and refill selection. The evidence should identify the assortment record actually selected, alongside a separate physical-pack acceptance result.
An operational handover can explain how remaining earlier sets are distinguished from revised ones. Preserve the composition record rather than overwrite it with the latest marketing name. These are proposed workflows, not customer cases or completed WEIMI bundle tests.
GS1 defines a fixed composition of two or more trade items combined and sold together as a single physical trade item.
Yes. GS1 says a change, addition or replacement of included trade items requires a new GTIN for the predefined assortment.
No. The source says the explicitly defined individual trade items have their own unique GTINs separate from the assortment identifier.
No. Establish whether there is a combined physical trade item. This article does not classify every software promotion under the rule.
No. Hardware descriptions form a public shortlist; bundle fit, dispensing, recognition and host mapping require separate acceptance.
GS1 calls for a unique GTIN at every existing level above the retail consumer item or base unit. Request the supplier-confirmed hierarchy.
Define the fixed physical set before reviewing its identifier change. Obtain the separate assortment and component GTINs, then request the revised assortment and existing higher-level records when an included item changes.
Demonstrate the host relationship and the physical pack through the contracted workflow. Keep software promotions, content compliance and pack suitability within their own evidence scope. One familiar set name does not establish one unchanged trade item.
Share the proposed physical assortment, supplier component records and any planned substitution. Request a configuration quote with the receiving, refill and actual pack-acceptance scope needed for that combined item.
Research: GS1 GTIN Management: Predefined assortment, definition, component changes and hierarchy, read 11 October 2026. Public WEIMI hardware evidence reviewed 10 October 2026. No candidate bundle compatibility, integration test or regulatory outcome is asserted.
