My Bestselling Candle Represents 40% of Production — Should I Dedicate Separate Bulk Fragrance Inventory and Production Days to That One SKU?

What 40% of production actually means

Take a unit making 7,500 candles of 200 g a month, where one scent is 40% of output. That scent alone is 3,000 candles, or 600 kg of scented wax: 552 kg of wax and 48 kg of oil at an 8% load on total candle weight. Planned in 10 kg loads of 48 good candles after 5% wastage, 3,000 ÷ 48 is 62.5, so 63 loads, needing 579.6 kg of wax and 50.4 kg of oil.

The other 4,500 candles are spread across the rest of the range. The bestseller is therefore not just the largest scent; it is larger than most of the others put together. That changes how its materials and melter time should be handled. It also means that any hiccup in its supply, its oil lot or its schedule is felt across the whole unit, not just on one shelf. The steps below reduce that exposure while keeping the rest of the range moving.

The question in the title is really four questions: should its oil be held separately, should it get its own days, should it get its own pouring equipment, and should it get its own melter. The answers come in that order, and each one costs more than the last.

Step one: its own oil inventory and reorder line

This is the step to take first, whatever else you decide. At 50.4 kg of oil a month, the bestseller uses more fragrance than any other single line in the unit. If it shares a general "fragrance" reorder check with the rest, a full-looking shelf of slow scents can hide the fact that the one oil that matters is nearly gone.

Give it its own reorder point, based on its weekly use and your own recorded supply gap, and count it every week rather than monthly. At about 50 kg a month, weekly use is around 11.7 kg over 4.3 weeks. As an example only, a two-week gap plus a one-week buffer would put the reorder point at roughly 35 kg.

A volume like this sits above the listed oil packs. Sandalwood, for example, is listed at 100 g ₹502.68, 500 g ₹2,513.40 and 1 kg ₹5,026.80. Anything larger is a quoted quantity, so ask on WhatsApp and request IFRA and MSDS documents for your records at the same time.

Step two: dedicated production days

Blocking the bestseller's loads together is the change that pays back fastest. Every switch between scents means cleaning the melter and pitchers, a new weigh-up of a different oil and a new batch sheet. Running the bestseller in a block removes those changeovers for 40% of your output.

How many days? That comes from your own measured loads per day. As an example: if your unit reliably completes six 10 kg loads a day, 63 loads is 10.5 days, so the bestseller gets about eleven production days a month, perhaps three days a week. At four loads a day it needs about sixteen days, which is most of the month, and the question of a dedicated melter starts to arise.

Write the block onto a fixed monthly calendar rather than deciding it week by week. When the bestseller's days are visible a month ahead, raw-material orders, staffing and D2C promises can all be planned around them, and nobody is tempted to give those days away when a slower scent looks urgent.

Step three and four: pitchers, then a melter

Dedicated pitchers are almost free by comparison. At ₹708.00 for a Large 600 ml Steel Pouring Pitcher, a set used only for the bestseller removes one of the easiest routes for another scent to carry over. Mark them clearly and keep them on their own shelf.

A dedicated melter is a real decision. The 10 kg Electric Wax Melter (Imported) is ₹21,240.00. It is justified when the bestseller's loads would keep that unit busy for most of its working week, and when your other melter can handle the remaining 60% alone. If the bestseller only fills two or three days, a dedicated melter sits idle the rest of the week, and dedicated days on a shared unit give you almost the same benefit.

What a bestseller week can look like

Using the same example of six measured loads a day, the bestseller needs about 15 loads a week to reach 63 in a month of roughly 4.3 weeks. One way to lay that out is two full days and a morning, with the rest of the range on the remaining time.

Placing the block at the start of the week has a practical advantage. The melter and pitchers begin clean after the weekend, so the first bestseller batch carries no residue from another scent. The full clean then happens once, on Wednesday, instead of after every batch. The figures are an example; build yours from your own measured loads per day and your actual share.

The risk of building around one scent

Dedicating inventory and days to one SKU makes production smoother, but it also concentrates risk. If 40% of your revenue depends on one oil, then a change in that oil, a delay or a lot that smells different affects close to half your business in one go.

Three habits reduce that risk. Keep a retained sample from each bulk lot so you can compare future lots and investigate complaints. Record lot numbers on every batch sheet so any issue can be traced to the candles it touched. And ask your supplier the continuity questions early: how long the oil has been made to the same formula, and how changes are communicated.

Keep the flashpoint on the batch sheet too. Sandalwood publishes 203°C and Jasmine 185°C, but some CSI oils publish flashpoints below 100°C, such as Roasted Coconut at 93°C. If your bestseller is one of those, its dedicated days need an especially firm rule: oil in only at the wax maker's stated temperature, never at the melter's top setting.

Finally, review the 40% figure every quarter. Bestsellers change. If the share drops to 25%, a dedicated melter may become the idle one, and the days you reserved should go back into the shared schedule.
