I Want to Make 100 × 200 g Lavender Soy Candles in 8 cm Glass Jars — Exactly How Much Soy Wax, Lavender Fragrance Oil, Wicks and Extra Material Should I Order?

The exact order, on one screen

Start from what the customer receives: a 200 g candle, wax and fragrance together. CSI writes fragrance load as a share of that finished weight, so at the 8% working load used here each candle is 16 g of Lavender and 184 g of wax. One hundred of them are 1,600 g of oil and 18,400 g of wax — the net bill of materials before a single allowance. Everything you order beyond that is cover for something specific: test candles, rejects, wax left in the jug, and glass that breaks. This page adds each one in a fixed order, names the figure it uses, and then rounds every line to a pack CSI actually lists in stock today.

That is ₹314.40 of CSI materials per saleable candle when the White Matte jar is used and Eco Thin C1 wins the wick test. It excludes labour, lids, labels, boxes, freight and GST. The White Matte jar is a candidate for your 8 cm jar, not a confirmed match: CSI does not publish its internal diameter or fill weight, so the section on your 8 cm jar shows how to settle it with one weighed test pour before you commit to 109 pieces.

Two numbers in the table matter more than the rest. The wax is 21.5 kg of bags for a 21.11 kg need — 387 g spare, roughly two candles' worth, and that is as tight as CSI's listed packs allow. The lavender is 1.85 kg for a 1.84 kg need — 14 g spare. Both are tight because every allowance was named and sized, not because anything was shaved. If you want more cover than that, raise one named allowance; do not add a vague "10% extra" on top, because that applies the same cushion twice. Whether to plan for 105 or 110 pieces is its own question in this cluster.

The bill of materials for one candle

A bill of materials (BOM) is the recipe for one finished unit, written as quantities you can buy. For a single-wick container candle it has six lines, and the first two come from one multiplication. Write it once, check it against a weighed candle, and every order after this one is the same table multiplied by a different number.

Wax and oil are priced at the average rate of the packs actually bought for this order: ₹598.98 a kilo for the Chunks and ₹5.26 a gram for the lavender mix of 1 × 1 kg + 1 × 500 g + 3 × 100 g + 1 × 50 g. The oil, at ₹84.16, costs nearly as much as the wax at ₹110.21 even though it is less than a tenth of the weight. That is normal for a scented candle and it is why the oil line deserves the most careful rounding.

The allowance stack, in the order it is applied

This is the step most shopping lists get wrong — not because the percentages are wrong, but because they are applied to the wrong things, or twice. Test candles are whole candles, so they come first and are counted like production candles. Rejects mean a candle has to be remade, so the wax, oil, wick and sticker inside it are lost; on this page the jar is cleaned and reused, and a jar that cannot be reused is breakage. Pour loss is wax and oil left in the jug and on the stirrer, so it applies only to wax and oil. Breakage is a glass problem, so it applies only to jars. Rounding to packs is last, because every earlier step works in grams and pieces, not bags.

Your 8 cm jar: what CSI can and cannot tell you

An 8 cm jar is your container, and its diameter is your figure. CSI does not publish internal diameters for any of its jars, and of everything in the catalogue only two fills are published: the Golden Aluminium Tin at 85 g and the Heart Cutout Velvet Jar at 50 g of wax. So there are two honest routes. Buy your own 8 cm jars from the supplier you already use and leave the jar out of the CSI order; or try a CSI jar as a candidate, and settle its fill with a weighed test pour before you buy production quantities.

The Salsa row deserves a sentence because it is the obvious mistake. "200 ml" is the volume of the jar to the brim, not a fill weight. Solid soy wax is lighter than water; using a labelled approximate range of 0.86–0.90 g per ml, 200 ml of wax weighs about 172 g–180 g at the brim, and a candle is never filled to the brim. A 200 g candle will not fit. The Salsa jar can still be the right jar for a smaller candle — the 150 g coffee post uses it — but not for this order.

Rounding to real CSI packs, and what is left over

Pack rounding is where a correct calculation can still become an expensive order. The rule is simple — the cheapest combination of listed, in-stock packs that covers each need — but the cheapest combination is not always the obvious one, so compute it. Here is each line for this order, with the leftover and what that leftover is worth at the price you paid.

Three pack quirks decide this order, and each one is worth knowing for every order after it. Chunks: the 500 g bag is ₹299.00, which is ₹598.00 a kilo — a rupee cheaper than the 1 kg and 5 kg bags at ₹599.00, and ₹1.90 cheaper than the 10 kg bag at ₹599.90 a kilo. Strictly, 43 bags of 500 g would be the cheapest way to buy 21.5 kg (₹12,857.00), but nobody wants to open 43 bags for ₹21.00; four 5 kg bags plus a 1 kg and a 500 g are the practical cheapest. Never buy two 10 kg bags here: they cost ₹18.00 more than four 5 kg bags for the same 20 kg. Lavender: its 100 g is ₹5.40 a gram, 500 g ₹5.24 and 1 kg ₹5.22 — a small but real step — while 50 g is the same ₹5.40 as 100 g, so a 50 g bottle is the cheapest way to cover the last few grams. Two 1 kg bottles would cost ₹10,442.00 and leave 164 g unused. Wicks: the Eco Thin C1 10-pack is out of stock on the 4 October re-check, so the smallest Thin pack is 20.

Every one of the four sits comfortably above an 8% working load where a ceiling is published, so the choice is not forced by the formula. It is a price and preference decision that only your own test candles can settle — CSI publishes no throw, frosting or adhesion data for any of them. If you have not chosen yet, the Bergamot Amber post builds the testing stage into the shopping list from the start, and the 50-candle vanilla post runs the same order in CSI 464.

The priced shopping list

This is the list to take to the store. CSI lines are priced from the live listing; non-CSI lines are examples you replace with your own quotes and are deliberately left out of the CSI subtotal, so the figure you compare against your budget is the figure you will actually pay CSI.

Tools are not in the subtotal because most makers already own them. If you do not, the ones that matter for this order are a scale (Candle Making Weighing Scale, ₹354.00), a thermometer (Pen Thermometer, ₹354.00) — Chunks' product page states fragrance addition at 80–90°C and pour at 75–80°C in its spec table — and centring help for 100 wicks (Wick Centering Device, ₹118.00 for 5). The full-plan post adds dye and the testing materials to the same list format.

Notice that the wax changes much less than the oil when the load moves, because the finished weight is fixed: every gram of extra oil is a gram less wax. That is the whole point of writing load as a share of the finished candle. 6% versus 8% and 10% versus 8% work through the purchasing difference in full.

What to buy now, and what to buy after the wick test

Not everything on the list should be bought on the same day. The rule this series uses: materials that every option shares can be bought early; the production quantity of anything that a test might change is bought after the test passes. On this order the wax, the lavender, the stickers and the jars are shared — whichever wick wins, you need them. The wick is not. CSI publishes no wick-size-per-diameter chart, so the wick for your 8 cm jar is decided by burning, and buying 100 of the wrong wick is the one avoidable waste on this list.

If you would rather hold back everything until the wick passes, the test stage on its own costs ₹2,563.42: 1 × 1 kg + 1 × 500 g of Chunks, 1 × 100 g + 1 × 15 g of lavender, one pack of 10 White Matte jars (or six of your own), the two test wick packs and one sticker sheet. The only reason to split the order that way is cash or uncertainty about the oil; on price alone the split costs you a little, because the 15 g and 100 g lavender bottles bought for testing are dearer per gram than the 500 g and 1 kg bottles in the full order. The wick-sample post covers how many wick options are worth testing, and the first-100-candles post applies the same now/later split to a first production run.

Which question in this series is yours

This page is the hub for the whole "exact candle BOM and shopping list" series, and for its first cluster: production shopping lists for 50 to 100 candles. Every post uses the same BOM convention, the same allowance order and the same rule about rounding to real CSI packs; each one starts from a different question. Find yours below.

Four more clusters start from a different pressure. The 500-piece wedding order scales the same method to large confirmed orders of 500–1,000 candles. The ₹10,000 start-up budget turns a fixed budget into a balanced first inventory. The 200 g luxury lavender candle in frosted glass starts from a product idea and builds its development BOM. Converting a finalised formula into a 30-day purchase order handles monthly, multi-SKU reordering.
