When Should a Distributor Stock Multiple Shisha Charcoal Cube Sizes?
Add another cube size only when the customer need, actual device fit, repeat demand and fulfillment scope support it. Use the decision tree to choose routine stock, a bounded trial or a confirmed-order route.

01 · A reason for the second size
Stock another size when it solves a distinct, evidenced need.
A distributor should stock multiple shisha charcoal cube sizes when the additional size meets a verified customer or equipment requirement, has credible replenishment demand and can be handled economically as a separate stock position. If those conditions are still unclear, a bounded trial or a separately confirmed customer order is a more useful next step than routine stocking.
A shisha charcoal cube size assortment is not stronger simply because it contains more dimensions. Each stocked size needs identification, product approval, allocation, picking controls and its own demand record. Dividing one pool of demand across several similar sizes can leave each variant moving slowly.
This guide answers whether a second size deserves recurring stock. Use the broader SKU assortment guide to plan the full range, including packs and price positions. A proposed dimension in this decision process is a buyer requirement, not a statement that Unimax currently produces or stocks it.
02 · Actual HMD compatibility
Verify the setup before treating size as a market gap.
Record the exact heat-management device model and version, bowl and operating setup associated with the request. Ask what the current cube cannot do and what the alternative is expected to change. A request for a larger or smaller cube is useful input; it is not proof that the size is necessary or that it performs better.
Evaluate identified samples against the written dimensions and tolerances, then check fit in the intended setup. Use consistent conditions for observations such as space, clearance, arrangement and handling. Link the result to the device and sample reference. The specialist HMD guide contains the detailed checks; this article uses their outcome to decide on stocking.
If the current approved size already meets the customer requirement, clarify whether the new request reflects a preference, pack difference or a separate use case. There may still be a commercial reason for another size, but record it honestly. Do not present a preference as a demonstrated compatibility failure.
When results are unresolved, keep the size in evaluation. Do not make a general statement that one dimension fits all HMDs or that a larger cube always provides a better session. Neither conclusion follows from a single setup.
03 · Customer concentration
One large request is different from diversified repeat demand.
Build a customer-by-size register showing unique account, relevant setup, requested quantity, time period, evidence type and repeat-order status. Remove overlap between a distributor forecast and the downstream accounts already included in it. Distinguish confirmed commitments from expressions of interest.
Calculate concentration using a defined basis: demand for the size from the largest account divided by total demand for that size over the same period and unit. A concentrated size is not automatically unsuitable. It requires a clear plan for what happens if that account delays, changes equipment or stops ordering.
Illustrative arithmetic only: if one account represents 80 of 100 planned cartons for a proposed size in the same period, it represents 80% of that forecast. The other 20 cartons do not establish enough independent demand to absorb the full stock if the main account pauses. These numbers are not a market benchmark or an approval threshold.
Where demand depends on one account, compare routine stock with a confirmed account-specific order or a limited allocation. Confirm feasibility and the actual commercial arrangement with the supplier and buyer. Do not assume a forecast reserves stock or guarantees that the account will take it.
04 · Order velocity
Measure each size in a comparable time window.
Track completed orders, net quantity dispatched, repeat accounts and usable stock separately by size. State the period and unit. Opening placements, samples, promotions and returns should remain identifiable so launch activity does not look like established replenishment.
Look at the time between meaningful orders and the quantities per order. One large opening delivery can create a high monthly average while leaving no evidence of the next order. Conversely, a stockout can suppress observed sales. Keep availability and lost-request notes alongside the movement record.
Compare the proposed opening quantity with lower-demand as well as base-case assumptions. If 60 hypothetical cartons are available for sale and the scenario assumes 15 cartons per month, simple coverage is four months. At five cartons per month it is twelve months. This is planning arithmetic, not a prediction, shelf-life statement or recommended stock level.
There is no universal order-velocity threshold for adding a size. Set your review conditions using your actual replenishment scope, storage, customer commitments and tolerance for remaining stock. Record what evidence would justify moving from trial quantities to recurring stock.
05 · Split-case costs
Check whether the warehouse can fulfill the demand you expect.
A customer asking for a few packs of each size may require opening cases, counting units, maintaining size identification and handling leftover packs. Record which configurations the supplier can confirm and which activities your own warehouse would perform. A mixed customer order does not establish that a factory mixed case is available.
Observe picking time, additional handling materials, leftover quantities and size-mix errors for a defined set of comparable orders. Separate measured costs from estimates. Keep the original pack and lot identity usable through the fulfillment process so a smaller order does not become an untraceable mix.
Calculate incremental fulfillment cost per completed order using the extra costs attributable to splitting and picking, divided by the matching number of fulfilled orders. For example, 120 currency units of additional handling across 30 comparable orders is four units per order. This hypothetical example is not a service rate or a margin claim.
Compare full-case demand, small mixed orders and account-specific supply as separate service options. Confirm the offered case configuration and order constraints before deciding. A second size with apparent demand can still be unsuitable for routine stock if the practical fulfillment burden remains unresolved.
06 · Make and revisit the decision
Approve a stocking route with conditions and an owner.
Use the decision tree below in order. It is a buyer planning tool, not an industry standard or an automatic supplier approval. Treat unknown evidence as pending rather than answering yes just to reach the stocking outcome.
Routine stocking needs an approved product reference, a distinct supported buying reason, credible repeat demand, understood concentration exposure and workable fulfillment. If the product is suitable but demand is early, define a limited trial quantity, target accounts, evidence fields and review point. If only one customer is ready, consider a separately confirmed order rather than pooling its forecast into general stock.
After a trial, review actual movement, repeat orders, remaining usable stock, handling exceptions and customer feedback by size. Ask whether the new size adds supported demand or mainly moves customers away from the current one. Keep total channel demand visible to avoid calling substitution growth.
Record the decision as stock routinely, continue a bounded trial, supply against a confirmed order, or defer. Name the product and pack reference, unresolved conditions, approval owner and next review date. Review the decision again when a major customer, equipment requirement or case configuration changes.

| Decision gate | Question to resolve | Branch / next action |
|---|---|---|
| 1 · Distinct need? | Does the proposed size solve a documented requirement the current size does not cover? | Yes → check fit. Unclear → clarify buyer evidence. No → defer routine stock. |
| 2 · Fit approved? | Has an identified sample met the agreed requirement in the actual intended setup? | Yes → review demand. Pending → evaluate samples. No → revise or defer. |
| 3 · Repeat demand credible? | Do account records support replenishment rather than just initial placements or interest? | Yes → assess concentration. Early evidence → bounded trial. No → defer or review a confirmed-order route. |
| 4 · Concentration understood? | Can you explain exposure if the largest account pauses, without double-counting demand? | Yes → check fulfillment. Unclear → resolve assumptions. Concentrated → review account-specific allocation. |
| 5 · Fulfillment workable? | Are case configuration, split-case handling, identification and extra costs understood? | Yes → confirm supply scope. Pending → measure and clarify. Unworkable → revise the service or pack proposal. |
| 6 · Current scope confirmed? | Are product, pack, order constraints and timing confirmed for the proposed commitment? | Yes → approve the selected stocking route and review date. No → keep the order release pending. |

Multiple-size stocking questions
Does a larger cube always fit an HMD better?
No. Evaluate the identified cube in the exact device and operating setup against the written requirement. General size labels do not establish compatibility.
Is one large buyer enough to justify a second size?
It may support a defined account order, but assess what happens if that buyer pauses before treating its demand as general recurring stock.
How many repeat orders are enough?
Set the evidence period and approval conditions for your account and replenishment scope. This guide does not impose a universal order count or velocity threshold.
Can a distributor combine sizes in one case?
Confirm the current packing offer with the supplier. If your warehouse would split cases, assess handling, identification, remaining packs and costs before offering that service.
