This becomes more important as the catalogue grows. A Korean food importer may begin with fifty products and gradually expand to two hundred or five hundred. New beverages, snacks, flavours and brands are easy to add because every supplier has something new to offer. Removing products feels harder. A product may have a few loyal customers, the sales team may want to keep it available, or the buyer may remember that it performed well during its launch. Over time the catalogue can accumulate products that continue to exist without making a meaningful contribution to the business.
A useful SKU review starts with a different question. Instead of asking whether the product sold, ask what the business had to commit in order to generate those sales. The answer includes inventory capital, container space, warehouse space, sales effort, compliance work and the opportunity cost of not using that money for stronger products.
Suppose Product A generates USD 30,000 of annual sales and Product B generates only USD 20,000. Product A initially appears more important. A closer look shows that Product A requires around USD 15,000 of inventory to remain available and turns slowly, while Product B needs only USD 4,000 because it sells quickly and can be replenished several times during the year. Product B may be using the importer’s capital much more productively despite generating lower total revenue.
This is why catalogue decisions should be based on the behaviour of the product inside the business, not simply its position on a sales report.
Start with repeat demand, not shipment-out numbers
The first useful signal is whether customers actually reorder the product.
Initial sales can be misleading. A distributor may place a new Korean snack into fifty stores and count the entire shipment as sales. From the importer’s perspective, the stock has moved. From the market’s perspective, the test has only started.
If those fifty stores do not reorder, much of the original sale was pipeline filling. The product moved from one warehouse to another but may not have moved through consumers.
Compare that with a product initially placed into only fifteen stores. If twelve of those stores reorder it every month, that product is producing much stronger evidence of underlying demand.
For this reason, an importer should know not only how many cartons were sold but how much of the volume came from repeat customers. A product that continuously needs new customers to replace the customers who stopped ordering it is very different from a product that builds an expanding base of repeat buyers.
Reorder frequency also matters. A retailer buying ten cartons every month provides a more predictable demand signal than one buying sixty cartons once a year. The annual volume may look similar, but the first pattern is easier to plan, replenish and finance.
This is particularly useful when evaluating trendy products. A viral Korean snack may sell extremely quickly during its first two months. If retailer reorders collapse after that, the importer should recognise the change before placing another large order based on historical averages that include the launch period.
Sales velocity should therefore be calculated over recent periods as well as over the full year. A product that averaged 100 cartons per month over twelve months but sold only 30, 25 and 20 cartons during the last three months is no longer behaving like a 100-carton product.
Purchasing should respond to the current pattern.
Gross margin is not enough
A product with a high gross-margin percentage can still make poor use of inventory capital.
Imagine a product landing at USD 10 per carton and selling at USD 15. The gross contribution is USD 5 per carton, or roughly 33% of the selling price before operating expenses.
Another product lands at USD 20 and sells at USD 24, producing only USD 4 per carton and a much lower percentage margin.
If the first product sells once every eight months while the second turns every six weeks, the second SKU can produce much more annual contribution from the same amount of working capital.
The importer should therefore look at gross contribution together with inventory turnover.
Suppose USD 10,000 invested in Product A produces USD 4,000 of gross contribution but completes only one inventory cycle each year. The same USD 10,000 invested in Product B produces only USD 2,000 per cycle but turns four times. Product B can potentially generate USD 8,000 of contribution over the year from the same capital base.
This is one reason aggressive purchasing discounts can be deceptive. A supplier may offer a very attractive price if the importer buys 300 cartons instead of 100. The unit margin improves, but if the larger quantity increases the holding period from two months to six months, the capital productivity may become worse rather than better.
The question should be how much gross contribution the SKU generates for the amount of money and time committed to it.
That is much closer to how the business actually experiences the product.
Inventory days reveal problems that sales reports hide
A normal sales report tells management what moved. An inventory-ageing report shows what did not.
Both are needed.
Suppose a product sells 200 cartons each year. That number sounds respectable until the importer discovers that 150 of the cartons sold during the first three months after launch and only 50 sold during the following nine months.
Another product may also sell 200 cartons annually but move at a steady rate of roughly 16 or 17 cartons every month.
The second product is far easier to purchase.
Inventory days also show whether too much capital has been committed relative to current demand. If a product sells twenty cartons per month and the warehouse holds 180 cartons, there are roughly nine months of supply already on hand.
Placing another order simply because the supplier is preparing a shipment makes little sense unless demand is expected to change substantially.
The importer’s purchasing system should therefore distinguish between a good product and a good reorder.
A product may remain commercially attractive while the correct purchasing decision is to buy nothing for several months.
This distinction prevents buyers from treating every active SKU as something that must appear in every container.
Shelf life changes how long the importer can wait
Food inventory cannot always be held patiently until demand returns.
Suppose a Korean snack has 500 cartons in stock and sells around 50 cartons per month. Ten months of inventory would already be uncomfortable. If the stock has only seven months of remaining shelf life and retailers stop accepting it with three months remaining, the business has an even shorter commercial window.
The importer may need to intervene long before the printed expiry date.
A healthy SKU review should therefore compare stock coverage with usable shelf life. If there are eight months of inventory but only five months of realistic selling time, the problem already exists even though none of the stock is technically near expiry.
This is also why older stock should not be hidden inside aggregate inventory numbers. If 100 cartons expire in four months and another 200 expire in ten months, the importer does not simply have 300 interchangeable cartons.
The older batch requires attention first.
A product that repeatedly creates expiry pressure deserves investigation even if the final stock is eventually sold through discounts. The buyer should ask why the problem keeps appearing. The MOQ may be too large. The supplier may be providing older stock. Sales may be weaker than expected. The business may be purchasing too frequently.
If the underlying issue cannot be fixed, the SKU may not belong in the catalogue.
Some SKUs look profitable because their real costs are hidden
A product-level margin report often includes landed cost and selling price. It may not include all the work required to keep the SKU alive.
Consider a slow product that sells to only four customers. The sales team repeatedly follows up with those accounts. Small orders have to be picked from the warehouse. The importer carries certificates and product information specifically for that line. Its label requires separate compliance work. The MOQ forces a quantity much larger than current demand, and the product takes a disproportionate amount of container space.
The nominal gross margin may still look healthy.
Operationally, the SKU may be weak.
This does not mean every internal cost needs to be allocated perfectly to every carton. That can become more complicated than useful. Management should at least recognise products that create unusual levels of work.
Compliance can be particularly important here. If a product requires additional registration, laboratory testing, special documentation or label treatment in the destination market, those costs should be justified by the commercial opportunity.
A high-volume product can absorb significant compliance work easily. A product selling twelve cartons per year may not.
The same issue arises when regulatory requirements change. A SKU that was previously simple to import may require new documentation or revised packaging. The importer should then reassess the product using the new economics rather than maintaining it automatically because it has always been listed.
Compliance is part of the SKU’s cost of existence.
Container space is capital too
For an importer using FCL shipments, weak products do not only occupy warehouse shelves. They occupy container capacity that could have been used for faster products.
Suppose a bulky Korean snack occupies 4 CBM in a container and generates USD 4,000 of expected gross contribution. Another category could use the same 4 CBM and generate USD 9,000 while turning faster.
The first product needs a strong strategic reason to keep receiving the space.
Perhaps it completes an important retailer assortment. Perhaps it attracts customers who then purchase other products. Perhaps the supplier requires it as part of a broader brand arrangement. Those can be legitimate reasons.
The important thing is to know that a trade-off is being made.
Container space should not be allocated simply because the product was included in the previous shipment.
As the business grows, the strongest SKUs should naturally take more of the available capacity. Weak products should either earn their space through margin, customer importance or strategic value, or gradually lose allocation.
This is one of the ways a mixed-container business becomes more efficient over time.
Early containers contain many experiments. Mature containers should contain more evidence.
Not every low-selling SKU should be removed
Purely numerical pruning can also damage a catalogue.
Some products have strategic value that is not visible in their direct sales.
A retailer may expect an importer to supply a complete range from a particular Korean brand. One slow flavour may need to remain available because the retailer wants the entire range.
A niche ingredient may sell in small quantities but attract restaurants or specialist customers who purchase many other products from the importer.
A product may also help establish a category before demand becomes large enough to justify stronger volumes.
These reasons are valid, but they should be explicit.
Management should know that the SKU is being retained for a strategic reason rather than mistakenly believing it is commercially strong.
This distinction helps determine how much inventory to hold. A strategically useful but slow product may deserve one or two months of carefully controlled stock rather than the same purchasing depth as a core seller.
It can remain in the catalogue without consuming unnecessary capital.
Reducing the quantity is often better than immediately dropping the product
SKU management should not become a binary choice between keeping everything and discontinuing everything.
Many weak products can be repaired through lower purchasing quantities.
Suppose a Korean sauce sells steadily but only at ten cartons per month. The importer has historically ordered 120 cartons at a time because the price is better at that quantity.
Every order therefore creates a year of inventory.
If the supplier or exporter can reduce the purchase to 30 or 40 cartons, the product may become perfectly healthy despite a slightly higher unit price.
The lower inventory commitment can reduce shelf-life risk and release working capital for faster products.
MOQ negotiation, mixed consolidation and ordering less frequently can all change SKU economics.
The importer should therefore diagnose why the product is weak before removing it.
If customers like the product but the MOQ is too large, the sourcing structure is the problem.
If the landed cost is too high because the carton is bulky, freight economics are the problem.
If the product receives strong first orders but no repeats, demand is probably the problem.
If retailers repeatedly ask for it but stock is unavailable because the supplier’s lead time is unreliable, supply is the problem.
Different problems require different decisions.
Dead stock needs an exit decision
Some products will eventually reach a point where waiting is more expensive than accepting a lower margin.
Suppose the importer has USD 8,000 tied up in a slow SKU. The stock has already been in the warehouse for five months, demand remains weak and the remaining shelf-life window is narrowing.
Management can protect the original intended margin and continue waiting, or it can reduce the price and recover perhaps USD 7,000 of the cash quickly.
The second option records a disappointing margin. It also releases capital that can be put into a product that turns several times per year.
The correct decision depends on the expected future sales and the size of the discount required, but the original purchase price should not become a psychological anchor.
That money has already been spent.
The relevant question is what decision creates the best result from today onward.
This becomes even more important as expiry approaches. Protecting a USD 2 margin per carton until the product becomes unsellable can destroy far more value than accepting a USD 1 margin several months earlier.
Good inventory management accepts small mistakes before they grow into large ones.
Build the catalogue from evidence
Over time, every SKU should begin to fall into a recognisable role.
Some products are core lines. They have repeat demand, healthy margins, predictable replenishment and deserve deep stock.
Some are supporting products. They sell consistently but in smaller quantities and should be purchased more carefully.
Some are tests. The business is intentionally learning whether demand exists and has limited the capital committed to them.
Some are strategic lines retained because they support an important customer, category or brand.
And some are exit products. The business has enough evidence that the capital belongs somewhere else.
These categories do not need to become a complicated scoring system. The purpose is to stop every product from receiving the same treatment.
A core beverage selling 500 cartons a month should not be managed like a new snack that has sold eight cartons.
A strategic niche line should not be judged purely on annual revenue.
A failed experiment should not quietly become permanent inventory because nobody made the decision to discontinue it.
The catalogue should change as evidence accumulates.
A mature Korean food importer is not defined by how many SKUs it can list. It is defined by how well those SKUs use capital, container space and shelf life while producing repeat business.
Adding a product is easy.
Knowing when it no longer deserves another carton is where the real purchasing discipline begins.
