My Calculation Says I Need 46 Kg of Soy Wax for an Order — Should I Buy Exactly 46 Kg or Round Up to 50 Kg for Production Safety?

What "46 kg" and "50 kg" actually mean on this catalogue

Most rounding-up advice in maker groups comes from suppliers who sell wax in 25 kg cartons — a real constraint, because if the only unit on offer is 25 kg then 46 kg forces you to 50 kg. CSI does not sell a 25 kg pack of anything; checked across the whole catalogue in September 2026, zero. The ladder here is 500 g, 1 kg, 5 kg and 10 kg, and one wax carries a fifth rung.

The exception, precisely: Natural Soy Pearl Wax is sold in 1 kg (₹450.00), 5 kg (₹2,124.00), 10 kg (₹4,248.00) and 50 kg (₹21,240.00) — the only wax pack above 10 kg on the store. CSI 464, Luxury Soy Chunks, Soy Pillar Wax and Coconut Soy CSI 468 all stop at 10 kg; Eco Soy CSI 400 stops at 5 kg.

So the real decision is narrower than "46 or 50". On Natural Soy Pearl Wax you are genuinely choosing between assembling 46 kg from smaller packs and buying one 50 kg bag. On every other soy wax you are choosing between six packs and five 10 kg bags — not a rounding decision at all, but a decision about whether you want 4 kg of spare wax.

The arithmetic, wax by wax

Every figure below is a published September 2026 variant price, multiplied out: the cheapest real combination making 46 kg, what it costs, what the round-up costs, and what the leftover is worth at the wax's own rate. Where a finding runs against CSI's commercial interest it is stated plainly.

Read the last column twice. In every row, the extra you pay to round up is almost exactly the market rate for the extra wax — four kilograms of wax at the price of four kilograms of wax, plus or minus tens of rupees. In the plainest possible terms: rounding up on this catalogue is not a saving.

Rounding up is a risk decision, not a price decision

Strip the discount out, as the table above does, and rounding up is a plain insurance question. You pay a known premium — ₹1,597.00 on Eco Soy CSI 400 up to ₹2,535.00 on Coconut Soy CSI 468, always at the wax's own rate — to cover one event: discovering mid-run that you are short. Price both sides of it.

The fourth row decides it for most people. 4 kg of spare wax is only a cost if you never use it. If you pour CSI 464 every month, buying 50 kg instead of 46 kg is not wastage — it is 4 kg of next month's wax at this month's price, and because the rate is flat you have not even lost the option value of buying later. Soy wax kept cool, dry, dark and sealed holds fine between runs. For a one-off wax the surplus is a genuine loss, and you should buy the exact build.

Where your 46 kg came from, and why it is probably already short

A figure like 46 kg comes out of a spreadsheet, and the spreadsheet usually contains two things you have stopped thinking about: a fragrance-load convention and a buffer. Both change the answer, and one changes it by more than the rounding decision does.

Start with the denominator. Fragrance load is a percentage of something, and which something moves the wax figure. Take 250 candles of 200 g at 8%. If that means 8% of finished weight, each candle is 16 g of oil and 184 g of wax, so 250 × 184 g = 46.0 kg — very likely where your number came from. If it means 8% of the wax weight, the same candle is 14.8 g of oil and 185.2 g of wax, so 250 × 185.2 g = 46.3 kg: three hundred grams apart at 250 units, widening in proportion to the order. Both conventions live inside CSI's own catalogue, because the Luxury Soy Chunks listing states its 13% ceiling as a percentage of total wax weight. Write down which convention your 46 kg used before anything else. Those ceilings — 13% on Chunks, 10% on CSI 464 — are wax-manufacturer formulation limits, not regulatory ones.

Then count the units you have not counted. A 250-candle order is not a 250-candle purchase. You need approval samples for the client to sign off and retained samples — jars from the run, labelled with the batch, kept on your own shelf — so a complaint in eight weeks is answered with the actual candle rather than a memory of it. Add two approval and three retained: 250 becomes 255, and at 184 g each, 255 × 184 g = 46.92 kg. Your 46 kg was already short before any buffer.

Six packs, and the order that shifts colour halfway through

One argument for the single big bag has nothing to do with money. Assembling 46 kg from six packs may mean more than one production lot, and soy wax from different lots can differ slightly in shade and crystal texture. On a single jar nobody notices; across one client's 250 candles side by side, a faint difference between the first eighty and the last eighty is exactly what a buyer photographs and sends back to you.

Where shade consistency across one large order genuinely matters — a hotel amenity run, wedding favours, anything seen as a set — the single 50 kg bag of Natural Soy Pearl Wax stops being about price at all. One bag is one lot. That is a specification argument, and a legitimate reason to pay ₹1,674.00 over the 46 kg build. On any other wax, ask about lot consistency on WhatsApp before assuming six packs match — the wax verification guide covers what to check on arrival.

The other rounding decisions in the same order

Wax is not the only line that needs rounding, and the other three behave differently — so buffer per material, never one flat percentage across the order. The failure modes are not the same: glass breaks and wax does not. Leftover wax is stock, so its buffer can be thin; jars arrive broken or crack on the pour, so theirs must be real; wicks weigh nothing and cost ₹5.90, so theirs should be generous; fragrance oil keeps but is the dearest line per gram, so it wants the tightest count. Figures continue the same worked order — 250 candles of 200 g at 8% of finished weight, so 46 kg of wax and 4 kg of oil — and the complete raw-material list is where to start that sheet.

Fragrance rounds in 1 kg steps, and there is no pack above 1 kg anywhere in the catalogue — not 2 kg, not 5 kg, not a drum. A 4 kg requirement is four 1 kg bottles of the same oil; the multiplication is the whole answer. The ladder tilts here too: Citrus Lemon is ₹2,832.00 at 1 kg (₹2.83/g) against ₹1,420.00 at 500 g (₹2.84/g), so buy in kilograms rather than halves. Message +91 7397976926 to discuss volume, but again: no slab, rate card or discount tier is published, so do not cost your candles against one. How much fragrance oil a candle business needs and buying fragrance oils in bulk in India work the volume side properly.

Wicks are the easiest decision on the list, because the ladder does not move at all. Eco Candle Wicks in Thin (C1) are ₹5.90 per wick at every pack size — ₹59.00 for 10, ₹118.00 for 20, ₹295.00 for 50, ₹590.00 for 100, ₹2,950.00 for 500, ₹5,900.00 for 1,000. Six sizes, one rate; Thick (C2) is likewise ₹9.44 per wick. Fifty spare C1 wicks therefore cost ₹295.00 against a ₹23,340.40 wax line — about 1.3% — for full cover against mis-centred wicks, wicks trimmed short and the two you drop on the floor. Buy the spares. The wick guide by diameter will save you a test batch, and the Candle Wicks collection is seven products.
