How Do I Identify Raw Materials That Are Shared Across Many Candle SKUs so I Can Negotiate Better Bulk Pricing Without Increasing Dead Stock?

Count SKUs per material, weight by spend, negotiate only the shared lines

Dead stock comes from one place: something you bought that no remaining product uses. A container wax that every candle in your range is poured in cannot become dead stock unless the whole range stops. A fragrance oil used in one scent becomes dead stock the week that scent is dropped. That asymmetry is the whole method. Count how many SKUs use each material, multiply by what you spend on it, and you have a ranked list of where volume buying is safe. The top of the list — shared, high-spend materials — is where a bulk price is worth asking for, because the extra stock will be used by whichever SKU sells. The bottom — single-SKU, low-spend materials — is where you buy small and often, whatever the price ladder says.

Before the method, one plain statement about pricing. CSI publishes no volume-discount figure. The listed packs are the only published price breaks — and for the shared materials in this example most are flat: CSI 464 is ₹507.40 a kilo in 1, 5 and 10 kg bags, White Matte jars are ₹70.80 each in fives and tens, Eco wicks are ₹5.90 (Thin C1) and ₹9.44 (Thick C2) in every pack. Quantities beyond the listed packs — wax beyond 10 kg bags, jars beyond the pack of 10 — are quoted on WhatsApp. So "negotiating" here means bringing CSI a clear, committed volume for a few shared materials and asking for a quote; this page shows how to build that volume without creating dead stock.

Build the commonality matrix

The example range is twelve SKUs: six scents, each sold as a 200 g candle in the White Matte Glass Jar (the reader's weighed fill — CSI does not publish this jar's fill) and as an 85 g candle in the Golden Aluminium Tin (CSI's published fill). All twelve are poured in Luxury Soy Wax CSI 464 at 8%. Burn tests approved Eco Thick C2 for the jar and Eco Thin C1 for the tin — the reader's own results; CSI publishes no wick-size chart. Three SKUs are coloured with red liquid dye. Monthly sales are the reader's examples: 150 jars and 120 tins.

The ranking is stark. Materials used by six or more SKUs account for 70% of the monthly CSI spend (₹37,700.00); the six oils and the dye together account for 30%. CSI 464 alone is 37% of the spend, and because all twelve SKUs depend on it, only ₹1,649.05 of its monthly stock rides on any single SKU. Japanese Cherry Blossom, the biggest oil, has ₹2,250.00 riding on each of its two SKUs. That is why the wax is the first line to negotiate and the oils are the last.

Raise commonality before you negotiate

Commonality is not fixed; it is a design choice. This range uses 13 distinct materials, an average of 4.8 SKUs per material. If one wick could serve both the jar and the tin, the range would drop to 12 materials and the average would rise to 5.2 SKUs per material — more volume on fewer lines, a stronger case for a quote, and less dead-stock risk. The catch is that a wick change voids burn tests. Whether one Eco size works in both containers is a test question, not a purchasing one: CSI publishes no wick-size-per-diameter chart.

These moves are covered in detail by standardising wax, jars, wicks and dyes across 10 SKUs and how much inventory complexity one wax, one jar and a small wick range removes. The point here is narrower: every move that raises a row's dot count makes that material safer to buy in volume, and every move that lowers it makes a volume deal riskier.

What to ask for, and how much to commit

When you ask for a quote on a shared material, the volume you commit to is the dead-stock lever. Commit to the forecast and a slow quarter leaves you holding the difference. Commit to a floor — the volume you are confident of even in a weak period — and the risk shrinks to almost nothing for a shared line. This page uses an example floor of 85% of the average month; use your own lowest recent month instead if you have it. On that basis the commitments for a quarter are about 99.12 kg of CSI 464, 395 White Matte jars and 314 Golden tins.

Ask about structure as well as price. A committed quarterly volume taken in monthly deliveries keeps cash and shelf space free while giving the supplier the volume certainty that justifies a quote — ask CSI on WhatsApp whether that arrangement is possible for your lines; it is not a published offer. Bring the matrix: material, SKUs using it, monthly need, the floor commitment and the pack sizes you want. A clear request is easier to price than "can I get a discount?".

This month's consolidated order

Until a quote changes anything, the right purchase is the monthly order at listed prices, bought in the cheapest real packs. Here it is in full — ₹53,496.84 of CSI materials for 270 candles, before labour, packaging, freight and GST.

Keeping shared stock from turning dead

Review the matrix every quarter, and immediately when you drop or add a SKU. Dropping a SKU removes dots: a material can fall from "shared by six" to "shared by three" without anyone noticing, and the volume commitment that was safe last quarter is no longer safe. Adding a SKU that reuses existing materials is the cheapest growth there is, because it raises commonality without adding a row. Safety stock by material role uses the same commonality idea to size buffers, and the reorder sheet carries the SKU count as a column so a falling count is visible.

Finally, keep the bulk decision and the stock decision separate. A quote can improve the price of a shared material; it does not change how much you need. Order quantities still come from monthly sales converted into requirements and one consolidated monthly order, with per-material reorder points deciding when.
