I Need the Same Candle Fragrance for Several Years — What Should I Ask a Supplier About Batch Consistency, Availability and Reformulation Before Building a Bestseller Around It?

The eleven questions

Most makers choose a bestseller the same way customers do: it smells good and it sells. Nobody asks the supplier anything until the day a reorder smells different or a size is out of stock in October. By then you have labels printed, repeat customers and a festive order book, and every option is expensive. The questions below take ten minutes to send. Send them in writing so the answers are on record, and send the same list to any supplier you use, including us.

Read that last column honestly. For most of the questions that matter over several years — lot identification, single-lot orders, reformulation notice, shelf life, restock patterns, reserved stock — CSI's published data gives no answer. That does not mean the answer is no. It means you need to ask, for the specific oil, and keep the reply. What is published is modest but real: GST invoicing, MSDS and IFRA documentation on request, and quotes beyond the listed packs on WhatsApp with no published discount figure.

The stock picture on the pull date

Availability is the one part of this page where we can show you evidence rather than questions. On 24 September 2026 the Fragrance Oils collection listed 93 products. The table summarises how their sizes stood that day. It is a snapshot, not a trend, and it cannot tell you how often any oil has gone out of stock in the past — but it is a fair picture of the risk a multi-year plan has to absorb.

Two readings follow. First, stock-outs are real and they are not confined to obscure oils: Sacred Sandal Ember — an obvious candidate for a sandalwood-led line — had only its 500 g in stock on the pull date, with the 100 g and 1 kg both out. A plan that depends on a 1 kg every month from that listing would already be in trouble. Second, the majority of the catalogue was fully or mostly available. Building on an oil with all its sizes in stock today does not guarantee next year, but it is a better starting point than one whose production size is already out.

What you hold yourself

Take a Sandalwood line selling 120 candles a month — your own figure; replace it with yours. Each 200 g candle at 8% uses 16 g of oil, so the line uses 1,920 g a month and 23,040 g a year. At the 1 kg rate that is ₹1,15,817.47 of oil a year. Material cost per candle is ₹267.34 with Luxury Soy Wax Chunks, an Eco Thin C1 wick and a White Matte Glass Jar, before labour, packaging, freight and GST.

The buffer is the big number, and it is working capital rather than cost: you use the oil, you just use it later. Its size should follow your restock risk. Because CSI does not publish lead times, the two-month buffer here is a planning choice, not a recommendation from data. If the supplier confirms reserved stock or scheduled deliveries in writing, you can carry less. If the oil is one of the 14 with a size already out, carry more or build on something else. I'm Making 500 Candles Across Five Fragrances — How Do I Divide My Fragrance Oil Purchase When Some Scents Are Expected to Sell More than Others? covers how to split stock across several scents by expected sales.

The retained samples are smaller than they look. At one lot a month, keeping 50 g of each costs ₹3,016.08 a year, or 2.60% of the oil the line uses. If several 1 kg packs arrive in one delivery, ask whether they share a lot; if they do, one sample covers the delivery and the figure falls. How to use the samples is set out in the new-batch comparison. The short version: every new lot is poured beside the previous one, in the same wax, before it goes into production.

Qualifying a backup before you need one

A backup is only a backup if it has already passed your tests. Makers who wait until the bestseller is out of stock end up choosing a replacement in a week, testing it for two days and hoping. Qualify it while there is no pressure. For a Sandalwood line, two sensible candidates from the same catalogue are Woody Oud and Santal Noir. We are naming them because their names place them in a woody family and both had every size in stock on the pull date — not because we have data showing they smell like Sandalwood. Only your test, and your customers, can say whether either is an acceptable substitute.

Choosing the oil to build on

If the bestseller has not been chosen yet, availability deserves a place in the decision alongside how the candle performs. Three oils show the kind of profile worth building on: all five sizes in stock on the pull date, prices that make a monthly 1 kg reorder practical, and — for Jasmine — a real saving at the kilo. Jasmine's 1 kg is 8.8% cheaper per gram than its 100 g, one of only 24 oils in the catalogue with a 1 kg saving of 5% or more. For most oils the kilo buys stock security rather than a lower rate, which is still the right reason to buy it for a bestseller.

Whichever oil you choose, the questions come first. Send them for the specific oil, keep the replies, and review them every six months along with the MSDS and IFRA certificate. If an answer changes — a size becomes a limited run, a document is reissued — you will hear it early, with a buffer on the shelf and a backup already tested.
