When Should Candle Businesses Start Production for Diwali?

Build the calendar backwards from the festival

Most festive schedules fail for the same reason: they are built forwards from today, so the cure lands wherever it lands. Built backwards from 8 November 2026, the schedule tells you something more useful — the date after which each decision stops being available.

Applied to 2026, with the festival on 8 November 2026, those blocks land on the following dates. They assume a cure of 14–21 days and a dispatch that leaves your hands by the start of November for anything travelling any distance.

Two things about that table are worth saying plainly. First, none of these dates is a supplier's delivery promise — CSI does not publish delivery timelines and this page does not estimate one. They are your dates, built around a cure you control. Second, the dates are deliberately expressed as "about", because a festive schedule that depends on a single exact day has no slack in it, and October is not a month that rewards plans without slack.

The one block that does not negotiate

A poured soy candle is not finished when it is solid. The wax continues to crystallise and the fragrance continues to bind into it for days after the top has set, and the difference between a candle burned at 48 hours and the same candle burned at 14 days is usually obvious in the room. That is why cure is the fixed block on a festive calendar and everything else is negotiable.

CSI's own pages are consistent with the general practice here, and it is worth quoting them rather than paraphrasing. The Luxury Soy Wax Chunks page states a cure minimum of 48 hours and ideally one to two weeks before burn testing. Several fragrance oil pages give 24 to 48 hours as a cure time. Across the trade, 14–21 days by fragrance family is the standard for soy container candles, with heavier vanillas, ouds and resins on the longer end and citrus and light florals on the shorter. Read the shorter figures as the earliest a candle can be tested, not the point at which it is at its best.

The calendar consequence is stark: between a 21-day cure and a 14-day cure there is exactly one week of extra pouring available, and between 14 days and nothing there is a reputation. If you are choosing what to cut on a tight schedule, cut the fourth scent, cut the second format, cut the printed box, and do not cut the fortnight.

How many pour days you actually need

Pour capacity is the block most people estimate wrongly, because they time one candle and multiply. What actually governs a pour day is melt capacity and cycle time: how much wax you can bring to temperature at once, and how long the whole loop takes — melt, add fragrance at the temperature the wax page states, stir, pour, set wicks, cool, clean the pitcher, start again. Here is that arithmetic for a 120 g candle, which is the size used for the worked run on this page.

Those figures are planning assumptions rather than tested rates, and your own kitchen will differ. What matters is the shape of the answer: at 25–30 candles an evening, a 300-candle run is ten to twelve pour sessions, which is three weeks of evenings with a weekend day in each. At 80 candles a fill, the same run is a long weekend. That is the entire argument for equipment, and it should be made with a number attached rather than with enthusiasm.

The honest version of that argument runs both ways. A 10 kg melter at ₹21,240.00 spread across a 300-candle festive season is ₹70.80 a candle, which is more than the wax in it — ₹63.93 at a 120 g fill and the 10 kg pack rate. Spread across 1,200 candles a year it is ₹17.70, which is a different conversation. A 1 litre Mini Electric Wax Melter at ₹2,360.00 across the same 300 candles is ₹7.87, which most festive runs can carry. Buy capacity when the calendar says you need it, not because the season feels big.

Three smaller purchases move a pour day more than most people expect. A Pen Thermometer at ₹354.00 ends the guesswork about when to add fragrance — the CSI 464 page gives 80–90°C as the working range for melting and pouring, and the Chunks page asks for fragrance at 80–90°C with two full minutes of slow stirring. A Steel Pouring Pitcher 600 ml at ₹708.00 or a Candle Wax Pouring Jug at ₹531.00 turns a wobbling pan into a controlled pour. And Wick Centering Devices at ₹118.00 each, or a Wick Setting Tool at ₹399.00, take the fiddliest minute out of every candle.

Your start date, by the size of the run

Run size changes the start date in two ways: more pour days, and more of the fiddly counted work at the end — wicking, labelling, boxing, packing. The table below assumes a single maker with a 1 litre melter for the smaller runs and help or a bigger melter for the larger ones. Every figure is a planning assumption.

The 300-candle run costed here is 300 jars at a 120 g fill in the Clear Glass Jar with Golden Lid, two scents, one wick size. In materials it is ₹19,281.20 of CSI 464 for 38 kg, ₹7,339.60 of Cinnamon Vanilla and ₹8,448.80 of Saffron Cedarwood at 1.6 kg each, ₹30,208.00 of jars, ₹3,020.80 of Eco Candle Wicks Thick (C2), ₹800.00 of wick stickers and ₹413.00 of care labels — ₹69,511.40 in all, or ₹231.70 a candle. The materials are the straightforward half. The ten to twelve pour sessions are the half that decides whether the date is met.

If you are already late: the recovery plan

This section assumes the worst version of the question: it is not 15 September any more, the plan exists only in your head, and the festival has not moved. There is a recovery path for each starting point, and they get shorter as the month goes on.

The last row is the one worth dwelling on, because it is the one nobody wants to write on a supplier's blog. If it is the end of October and you have not poured, buying 20 kg of wax will not produce a cured festive candle. It will produce excellent December and January stock, and a brand that quietly sells uncured candles into its biggest gifting week of the year has spent its reputation to make one month's revenue. Sell what is cured, be straightforward with late enquiries, and put the season's energy into the wedding and corporate orders that run from November onwards — the wax keeps, and the CSI 464 page states 60 months of shelf life in cool, dry storage.

Where a late run genuinely has to happen, four levers actually work and one does not. The ones that work: fewer scents, because every scent is a separate melt, a separate label and a separate test; one format, because a single vessel and a single wick size removes every changeover; a one-pour wax, because a second top-up pour costs a whole extra handling pass on every candle — Eco Soy CSI 400 is sold as a container wax that often needs one pour and no additives, and Premium Coconut Soy CSI 468 is described as a one-pour container wax; and a smaller fill, because 90 g candles pour faster and stretch the wax further, though they cure on the same clock as everything else. The lever that does not work is shortening the cure, and no amount of calendar pressure changes that.

What an Indian October does to the schedule

Two physical realities shape a festive pour in India, and both belong in the schedule rather than in a list of excuses afterwards.

Heat. In much of the north and west, October afternoons still run well above 30°C, and a room that swings from 24°C at night to 34°C in the day makes soy tops move. Candles set on a hot afternoon and cooled quickly in the evening are the usual cause of sunken centres, rough surfaces and wet-looking tops in a festive batch. Pour in the cooler part of the day where you can, let the candles cool slowly and undisturbed rather than in front of a fan or an air conditioner, and keep the cure space away from the window. A heat source passed briefly over a rough top will smooth it, but the better fix is upstream: pour a degree or two cooler and let the candle cool slowly in one place.

Humidity. On the coasts and in the east, October still carries moisture, and an opened bag of flakes left loosely closed in humid air clumps. The CSI 464 page asks for cool, dry storage away from sunlight and moisture, and in a Mumbai or Kochi workshop that instruction earns its keep. Reseal every opened pack, draw from one pack at a time, keep fragrance oil sealed and upright, and wipe jars with Isopropyl Alcohol Spray at ₹383.00 before pouring rather than after, because a dusty or damp jar is where adhesion problems start.

Traffic, in every sense. The fortnight before the festival is the busiest time of year for couriers, for markets and for your own household. Two practical consequences: dispatch outstation orders earlier than feels necessary, and do not schedule pour sessions in the last week, because that is the week family, stalls and deliveries will take. Build the schedule so the final ten days contain no production at all. If the calendar cannot accommodate that, the run is too big.

The 2026 festive calendar, week by week

Here is the whole schedule for a 300-candle run in the shape most people actually use it: one row a week, from this week to the festival. Adjust the numbers to your own run size; the sequence does not change.

Notice that production stops a full fortnight before the festival and that the last three weeks are entirely about getting candles to people. That is not conservative planning; it is what a 14–21 day cure and a busy courier network make necessary. A schedule where you are still pouring in the first week of November is a schedule that has already decided to sell uncured candles, whether or not anyone has said so out loud.

Finally, a short checklist for the last review before you commit. Is the last pour date written down and agreed with yourself. Is every material line confirmed as available rather than assumed. Has one candle in the exact vessel with the exact wick been burned. Is the cure space booked, level, shaded and out of the daily traffic of the house. Are the corporate quantities confirmed in writing before you pour against them. And is there a week of slack somewhere in the schedule — because there will be one batch that goes wrong, and the only question is whether you planned for it.
