CSI Bulk Orders · Deadline Buffers
Expected rejects belong in the pour count; the unexpected belongs in the calendar. Build the buffer from its parts, promise the later date, and run the workshop to the earlier one.
2 days on 16
time buffer (12.5%) for 1,500 wedding candles (worked example) · CSI live pricing, October 2026
Quick answers — read this first
How much spare capacity should I keep when I promise a bulk deadline? Build it from four parts: expected rejects (poured up front, from your history), breakage (spare pieces on the shelf), one remake day for defects found at final QC, and one lost day per couple of weeks of pouring. In the worked example (1,500 wedding candles at a demonstrated 100 a day) that is 2 buffer days on 16 production days, a 12.5% time buffer, inside the 10–15% band many makers use.

How do I express it? As two dates. Plan to finish on day 24 (the internal target); promise the client day 26. The naive sum, 1,500 ÷ 100, would have promised day 17.

Is two days enough? It absorbs one bad thing: a lost day, a reject rate double your history, or a late remake. Two bad things land exactly on the client date. A late material delivery misses it, which is why materials are confirmed before day 1.

Does it change what I buy? The time buffer and the material buffer must match: 1,590 pours of wax and oil (extras and 5% loss inside), 1,622 jars and wicks with 2% breakage. CSI materials: ₹3,91,222.00.
The short answer
The formula: time buffer = remake time + lost-day allowance, on top of production days that already include your expected rejects. Here 1 + 1 = 2 days on 16: 12.5%.
Two dates: internal target day 24, client date day 26. Never tell the client the internal date.
Stress-tested: one lost day or rejects at 10% finish day 25; both together, day 26; jars three days late, day 27: a miss.
Never spend the buffer on: a client change request (that is a new date or a fee), or a shorter set time on the last pour.

Straight answer
How much spare production capacity should I keep for breakage, rejected candles and remakes when promising a bulk-order deadline?
Keep two kinds of spare and do not mix them up. Expected losses go into the pour count: pour your order plus planned extras plus your historical reject rate (1,590 pours for 1,500 in the worked example, at 5%), and hold spare jars and wicks for breakage (2%). That is the material buffer, and the days to pour it are already in your production days. The unexpected goes into a time buffer: one remake day for defects found at final QC (a remake needs a new melt and a fresh set), and one lost day for every couple of weeks of pouring. In the example that is 2 days on 16 production days, 12.5%, which sits in the 10–15% band many makers use as a judgement. Then turn it into two dates: plan to finish on day 24, promise day 26. Stress-test the promise: if one bad thing still lands before day 26 and two land on it, the buffer is right. If the client's date is earlier, cut quantity, add capacity or split delivery; do not cut the buffer.
One line: rejects in the pour count, the unexpected in the calendar: 2 buffer days on 16 (12.5%), finish day 24, promise day 26.
The breakage buffer lives in the jars: 1,622 Clear Glass Jars with Golden Lid (150 gram) for 1,590 pours (₹1,53,872.00 for 1,630). It is in stock on 7 October 2026 in packs of 10 and 20, the same price per jar in either; confirm batch and dispatch for this quantity on WhatsApp before you promise.

The order and your real rate, as numbers

The title has no figures, so this is a worked example. The one input you must not guess is your rate.
Worked-example inputs · a wedding order
All figures labelled worked examples · "demonstrated" = the average of five real production days, not your best day
Input Figure Note
Saleable candles 1,500 The wedding order
Fill and load 150 g at 8% = 12 g oil + 138 g wax Clear Glass Jar with Golden Lid (150 gram): page states "150g fill capacity"
Demonstrated rate 100 candles a day Wick, pour, QC, lid, label, pack, all included
Planned extras 15 Client samples, QC retains, burn checks (1%)
Historical reject rate 5% Sinkholes, off-centre wicks, chips, label errors
Pours 1,590 = 1,500 + 15 + 75 Expected rejects poured up front, not remade later
Base production days 16 (15.90) 1,590 ÷ 100
Set-up and tail 2 + 3 working days Sample, PO, materials in; 72 h set, final QC, pack
Week 6 working days, day 1 a Monday Calendar day = working day + Sundays passed

"Demonstrated" matters. A maker who poured 140 on her best day and averages 100 over a normal week has a rate of 100. Plan on the best day and the buffer is spent before the first problem. If you have never run five consecutive production days at this jar and this fill, time a trial before you promise anything (the timed-trial capacity post).

The naive count, 1,500 ÷ 100 = 15 days, forgets extras and rejects (90 more pours), set-up, the set and the pack, and the bad day. It would put the hand-over on day 17: nine days early on paper and impossible in practice.

Building the buffer, part by part

Expected losses are a quantity. Unexpected losses are a calendar. Stack them once, not twice.

The commonest mistake is to add a percentage for rejects to the pours and another percentage to the days for the same rejects. The table separates what is counted where.

The buffer, part by part · 1,500 × 150 g · worked example
Where each risk is covered: in the pour count (material buffer) or in the calendar (time buffer) · never both
Risk How big (worked example) Covered by Days it adds Why there
Expected rejects 5% = 75 pours Pour count 0.75 (inside the 16) You know it will happen; pour it while the melter is hot, same lot
Planned extras 15 pours Pour count 0.15 (inside the 16) Samples and retains are part of the job
In-house breakage 2% of jars and wicks Spare pieces none A broken jar is replaced from the shelf, poured with the next melt
Defects found late 2% = 30 candles at final QC or packing Time: remake day 1 A remake needs a new 4.54 kg melt and its own 72 h set
A lost day power, illness, a melter fault Time: lost-day allowance 1 One per about two weeks of pouring (judgement)
Time buffer 2 days 12.5% of 16 production days

Why is the remake day separate from the reject pours? Because the rejects you find early, at each day's QC after the 72-hour set, are replaced from the loss-buffer pours already made. The ones you find on the last days, in final QC, packing or a dropped carton, have nothing left to replace them from, and a candle poured today is not ready for three days. The remake day is where those 30 get poured, early enough to set inside the tail. Its material is about ₹7,234.99 at bulk prices; its real cost is the day.

To size your own, work through it in this order, with your records beside you:

1
Measure your demonstrated rate.Average candles a day over five real production days in this jar and fill, every station included: 100 in the example.
2
Pull your reject history.Rejects as a share of saleable candles over your last few runs. No history? Use a cautious figure and say so: 5% here.
3
Build the pour count.Order + planned extras + expected rejects = 1,590. This is the material buffer, and its pouring time is in your production days.
4
Add a remake day.For defects found in final QC and packing (30 here), poured early enough to set before cartoning.
5
Add lost days.One for roughly every two weeks of pouring; more in monsoon, during power-cut seasons, or with a new team.
6
Check the percentage and stress-test it.2 on 16 is 12.5%. Then run the table below: one bad thing must finish before the client date.
Where 10–15% comes from
It is not an industry statistic; it is what the parts usually add up to for a two-to-four-week run: one remake day plus one lost day on 14–20 production days is 10–14%. A first run in a new jar, a reject rate you don't actually know, or monsoon humidity in a non-air-conditioned room are reasons to go higher. A product you have made for a year, on a short run, can go lower, but rarely below one remake day.
Mistake: using an 8% reject rate in the pours "to be safe" and then a 15% time buffer as well. Why it fails: both cover the same rejects. You buy material you won't use and promise a later date than you need, and a client comparing quotes notices the date first. Fix: rejects go in the pour count at your measured rate; the time buffer covers only what pours can't (late defects and lost days). The material side is the production-buffer post and the 4% reject-rate post; whether samples and retains are separate lines is the samples-and-retains post.

Two dates: the internal target and the promise

The buffer is real only if the workshop works to the earlier date.

Lay it out in working days, then convert: 2 set-up + 16 production + 3 tail = 21 working days, calendar day 24. Add the 2 buffer days and it is 23 working days, calendar day 26. The first is the internal target on the workshop wall; the second is the date in the client's purchase order.

From working days to two dates · 6-day week, day 1 = a Monday (worked example)
Calendar day = working day + Sundays passed · the buffer sits before the tail so remakes can set
Block Working days Calendar days What happens
Set-up 1–2 1–2 Signed sample, PO and advance, materials in and checked
Production 3–18 3–20 1,590 pours at 100 a day; daily QC from day 6 after each 72 h set
Buffer 19–20 22–23 Remake day and lost-day allowance; if unused, the tail moves up
Tail 21–23 24–26 72 h set on the last pours, final QC, cartons, hand-over
Internal target 21 day 24 Buffer unused
Client date 23 day 26 Buffer fully used

Run the workshop to day 24. Track it daily: candles poured against the plan, rejects against 5%. When you fall behind, you know on the day which part of the buffer you are spending, and you can still choose overtime before the buffer is gone. A team that is told the client date works to the client date, and the buffer evaporates in small slips.

Mistake: putting the buffer at the very end, after the tail. Why it fails: a remake poured after final QC needs another 72-hour set, so a buffer day at the end cannot actually be used for a remake: it only covers packing. Fix: place the buffer before the tail, as here, so anything poured in it still sets in time. Cure is calendar time, not labour (shortening cure for a corporate order explains why squeezing it is a throw risk).

Stress-test the promise before you make it

A buffer is the right size when one bad thing is absorbed and two land on the date, not after it.
Stress tests against day 24 and day 26 · worked example
Each row: what happens, the working days it adds, the finish day · rejects at 10% means 1,665 pours, 17 production days
What goes wrong Working days Finish (calendar day) Against the client date
Nothing: buffer unused 21 24 2 days early
One production day lost 22 25 absorbed
Rejects at 10% instead of 5% 22 25 absorbed (and the extra material must exist)
30 late defects remade 22 25 absorbed by the remake day
A lost day and 10% rejects 23 26 on the date, nothing left
Jars arrive 3 days late 24 27 misses by a day

Two rows deserve a second look. Rejects at 10% are absorbed in time, but only if the material is there: 75 extra pours need about 11.36 kg more mix, 75 more jars and wicks. Either buy that cover or accept that a doubled reject rate means a short delivery. The late delivery is the one the buffer cannot save, because it pushes every day after it. That is why materials are confirmed in writing before day 1, and why "it usually comes in two days" is not a plan. CSI does not promise dispatch or transit times for bulk quantities; confirm on WhatsApp before you give the client a date.

The decision rule. Promise a date only if it is on or after your internal target plus the time buffer: here, day 26 or later. If the client needs day 24, the honest answers are a smaller first delivery (keeping the buffer, 14 production days fit 1,400 pours, about 1,319 saleable candles), more capacity (a second person, which you must prove with a timed trial), or the rest a few days later. Promising day 24 with no buffer is betting the wedding on nothing going wrong in three and a half weeks.

Material buffers that match the time buffer

A remake day is useless without the jar, the wick and the wax to remake with.

The purchase sheet carries the same assumptions as the calendar: 1,590 pours (extras and 5% loss inside), 1% heel, and 2% extra jars and wicks for in-house breakage, which also supplies the remake day. The sheet assumes your proven formula is Luxury Soy Wax Chunks, Japanese Cherry Blossom at 8% and an Eco C1 wick in the Clear Glass Jar with Golden Lid (150 gram).

Purchase sheet · 1,500 × 150 g at 8% · CSI live pricing, 7 October 2026

CSI materials ₹3,91,222.00 ₹260.81 per saleable candle

₹260.81 per saleable candle is CSI materials only, buffers included; it excludes labels, cartons, labour, freight, GST and marketing. One poured candle carries about ₹241.17 of CSI materials at these prices, so the 90 extra and loss-buffer pours are about ₹21,704.96: the price of turning "about 1,500" into "exactly 1,500 on time". How rejects and failed batches change your true cost per candle is the true manufacturing cost post; whether wax left in pitchers belongs in that cost is the pitcher-heel post.

Argued against our own interest: nothing in this sheet gets cheaper per unit in a bigger pack. The jar is ₹94.40 in 10s and 20s, C1 is ₹5.90 at every buyable pack, and the Chunks 10 kg bag costs ₹9.00 more than ten 1 kg bags. Buy for the pours, round to the smallest covering packs, and do not "round up for safety" a second time: the buffer is already in the count.

Spare pieces are cheap insurance; spare oil is not
Eight spare jars and 18 spare wicks cost little and let you remake on the spot. Spare oil is different: 229.2 g of Japanese Cherry Blossom remains, enough for about 19 more candles. If your reject rate is genuinely unknown, buy the 20th kilo (₹96,840.00 for 20 kg) rather than discover a short melt on day 17, and keep one lot. Jar pieces get their own buffer logic in the jar-and-wick buffer post.

Guarding the buffer

A buffer you give away in week one is not there in week three.

Client changes. A new label proof on day 8, a scent swap on day 10, an extra 100 candles "while you're at it": each eats buffer days the client does not see. Write in the order that changes after sample approval move the date and may carry a fee, and that the date is "calendar day 26 from signed sample and advance". Practical judgement, not legal advice; the advance itself is the advance post.

The never-skip list. The buffer is for remakes and lost days, not for skipping a test. The candle must already be proven in this jar with this wick and oil at 8%, burned to the end; burn-check candles from early and late melts are burned during the run against the approved sample; the last pours get their full set before cartoning. Cutting any of those to rescue a date turns a late order into a bad one (the never-skip post).

Lot changes. If a second lot of jar, wax or oil arrives mid-run, compare it with the first before using it: jar dimensions and lids; wax and oil by cold sniff, colour in wax and a short burn. That check costs part of a day, and it belongs to the buffer only if you planned for it. Ask about lots before day 1 instead.

Mistake: telling the client "we have a buffer, so we can absorb your change". Why it fails: the buffer was sized for your bad luck, not their new requirement, and once it is spent on a change, the next power cut misses the wedding. Fix: keep the buffer private, price and date changes separately, and hold the internal target on the wall. The scored version of whether to accept at all is the go / no-go matrix.
This page is for you if you have a firm quantity and a measured daily rate, and you are about to give a client a delivery date. It is not enough if you have never run five straight days at this jar and fill (measure first), or if the candle is new (development first). Ask the client first whether a split delivery is acceptable: it is often the cheapest buffer of all (6319 covers the intake questions).

What to buy, and how much spare

Four items for the worked-example wedding candle, chosen on page statements, price and stock on 7 October 2026. CSI publishes no burn or throw data, so nothing is ranked on performance. Each card says how much spare to carry and when not to buy.

1
jar · 150 g fill · the piece that breaks
Clear Glass Jar with Golden Lid (150 gram)
The worked-example wedding jar, and the line where breakage buffers matter most: it is the dearest material in the candle at ₹94.40 a jar. The page states "150g fill capacity", an outer diameter of 7 cm and "Safe for hot pour up to 85°C"; it states no internal diameter. Argued against our own interest: it costs the same per jar in 10s and 20s, so cover 1,622 with 81 × 20 + one 10 (₹1,53,872.00) rather than 82 × 20 (₹1,54,816.00). Limitation: the largest pack is 20, so 1,630 jars is 82 packs: ask on WhatsApp whether they can come from one batch before you promise a date.
Pack Price Per jar For this order
Pack of 10 ₹944.00 ₹94.40 the top-up pack
Pack of 20 ₹1,888.00 ₹94.40 81 of these + one 10 = ₹1,53,872.00

wax · container soy · no bulk saving
Luxury Soy Wax Chunks for Jar / Container Candles
The worked-example wax, assumed proven in this jar. The page claims "up to 13% fragrance load capacity" and "Clean burning with minimal soot"; in the text we captured it states no pour temperature, so follow your proven process and keep the pour within the jar's stated 85°C. Argued against our own interest: the 10 kg bag costs ₹9.00 more than ten 1 kg bags, and the 500 g bag is the cheapest per kilo: 222 kg as 500 g bags would be ₹1,32,756.00, ₹420.00 less, at the price of 444 bags to open. Buy whichever your floor can handle.
Size Price Per kg 150 g candles at 8% (138 g wax) Note
500 g ₹299.00 ₹598.00 3 cheapest per kg
1 kg ₹599.00 ₹599.00 7
5 kg ₹2,995.00 ₹599.00 36 same per kg as 1 kg
10 kg ₹5,999.00 ₹599.90 72 ₹9.00 more than ten 1 kg
222 kg = ₹1,33,176.00. Buy 10 kg — ₹5,999.00

fragrance oil · floral · the wedding scent
Japanese Cherry Blossom Fragrance Oil
The worked-example wedding scent. The page describes "sweet cherry and soft pink petals opening into a rose and jasmine heart, grounded by warm sandalwood and musk" and states "6-13% for candles". Chunks also claims up to 13%, and the lower ceiling governs; 8% is well inside both. The 1 kg is the cheapest per gram (₹4.84 against ₹5.00), ₹158.00 less than two 500 g bottles. Limitation: 19.5 kg is a big draw on one oil, and a second lot found mid-order is a buffer day you did not plan: ask about lots first.
Size Price Per gram 150 g candles at 8%
15 g ₹104.00 ₹6.93 1
50 g ₹270.00 ₹5.40 4
100 g ₹500.00 ₹5.00 8
500 g ₹2,500.00 ₹5.00 41
1 kg ₹4,842.00 ₹4.84 83
19.2708 kg needed: 19 × 1 kg + 500 g = ₹94,498.00. Buy 1 kg — ₹4,842.00

wick · pre-tabbed · flat per piece
Eco Candle Wicks — Thin (C1)
On the sheet only because the worked example assumes C1 is the wick this 7 cm jar was burn-tested with; the page states no length or jar range in the text we captured, so a wick is proven by a burn test, never by a size chart. Every buyable C1 pack is ₹5.90 a wick; the 10-pack is out of stock on 7 October 2026, so 1,622 wicks are covered by 1,000 + 500 + 100 + 20 + 20 = 1,640 (₹9,676.00), cheaper than adding a 50 (₹9,735.00).
Pack Price Per wick For this order
Thin (C1) / 10 ₹59.00 — Out of stock on 7 October 2026
Thin (C1) / 20 ₹118.00 ₹5.90 top-up
Thin (C1) / 50 ₹295.00 ₹5.90
Thin (C1) / 100 ₹590.00 ₹5.90 top-up
Thin (C1) / 500 ₹2,950.00 ₹5.90 part of 1,640
Thin (C1) / 1,000 ₹5,900.00 ₹5.90 core
₹5.90 a wick at every buyable pack. Buy C1 1,000 — ₹5,900.00

Skip: extra wax "for safety" beyond the sheet (the loss pours are already there), and a second fragrance as a back-up you have never burned in this jar. Argued against our own interest: don't order the 1,630 jars until the client has signed the sample and paid the advance; a buffer on an unconfirmed order is just stock.

Wedding season is commonly cited as roughly November to February, and Diwali falls on 8 November 2026, so jar and oil demand can be high just when your buffer needs materials to arrive on time. CSI cannot promise dispatch dates, lot continuity or stock depth for these quantities in advance, so send your list on WhatsApp before you give the couple or the planner a date; we will confirm what we can supply and when it ships, with a GST invoice.

The CSI principle
Put expected losses in the pour count and unexpected ones in the calendar, then promise the later date and work to the earlier one.
Worked example: 2 buffer days on 16 (12.5%); internal target day 24, client date day 26; one bad thing absorbed, two on the date.
"Your buffer is for the day the power goes, not the day the client changes the label."

Why trust this guide

CandleMakingSuppliesIndia sells the jars, wax, oil and wicks named here, and does not sell finished candles. This page still tells you that nothing on this sheet is cheaper per unit in a bigger pack, that our 10 kg Chunks bag costs more than ten 1 kg bags, not to round up for safety twice, and not to order jars before the client signs.

Every CSI price was checked on the live store on 7 October 2026, size by size. Every item priced here is in stock on that date; the Eco C1 10-pack is out of stock and is not used. Stock depth, batch continuity and dispatch times for bulk quantities are not published on product pages: confirm them on WhatsApp.

The order, daily rate, extras, reject and breakage rates, late-defect rate, set-up and tail days, lost-day allowance and stress-test delays are labelled worked examples, and the 10–15% band is a judgement, not a statistic; replace them with your records. This is practical business judgement, not legal advice. For bulk pricing, stock confirmation, GST invoicing, and MSDS and IFRA documentation on request, message us on WhatsApp at +91 7397976926.

Frequently asked questions

How much buffer time should I add to a bulk candle order deadline?
Enough for one remake day and one lost day per couple of weeks of pouring, on top of production days that already include your expected rejects. In the worked example that is 2 days on 16, 12.5%, inside the 10–15% band many makers use.
Should I add rejects to the quantity or to the deadline?
Expected rejects go into the quantity: pour your order plus your historical reject rate (1,590 pours for 1,500 at 5%). The deadline buffer covers only what extra pours cannot: defects found late, which need a fresh melt and set, and lost days.
How do I set an internal deadline for a candle order?
Plan the job without the buffer: that finish date is the internal target (day 24 in the example). Add the buffer days to get the client date (day 26). Run the workshop to the internal target and track it daily.
What breakage allowance should I use for candle jars?
Use your own breakage history. Without one, many makers start around 2% of jars for in-house handling, kept as spare pieces so a broken jar can be replaced and poured with the next melt. Transit breakage is a separate packing question.
Can I shorten the cure time to make up lost days?
Not without risk. The set and cure are calendar time, and shortening them can leave hot throw weaker than the approved sample. Place your buffer before the final set so remakes still get their full time.
What if the client's date leaves no room for a buffer?
Offer a split delivery, a smaller first batch (about 1,319 saleable candles fit by day 24 with the buffer kept in the example), or more capacity you have actually proven. Promising with no buffer means any lost day misses the date.
Spare capacity for a bulk deadline
Rejects in the pour count, the unexpected in the calendar, and two dates on the wall.
2 buffer days on 16 production days, day 24 internal and day 26 promised, ₹3,91,222.00 of CSI materials in the worked example. Send us the list before you give the date, and we will confirm stock and dispatch, or tell you plainly what we can't promise.

Editorial standards & sources
About this guide: part of CSI's cluster "Can I actually accept this order?" (6301–6320) in the series on bulk corporate and wedding candle orders × raw materials. It covers how much spare capacity to keep for breakage, rejects and remakes when promising a deadline: the buffer built part by part, two dates, stress tests, and a purchase sheet whose material buffers match the time buffer.

Customer reviews: The six reviews at the top of this page are genuine, published Judge.me reviews left by CSI customers on the product pages named on each card — Black Glass Jar with Black Lid (150 gram) (Deliveries Starting 5th Dec), Ceramic Jar for Candle Making, Clear Glass Jar with Golden Lid (150 gram), Luxury Soy Wax Chunks for Jar / Container Candles. They are general product reviews, not assessments of the bulk-order advice on this page. Names, star ratings, dates and products are as recorded by Judge.me and wording is unedited. "Verified buyer" appears only on reviews Judge.me recorded as verified — Soumili Gope, Biny Abraham, Sakshi Jain, Kaushiki Satarkar, Jinal Patel.

Non-price figures: the title gives no figures. The 1,500 × 150 g order, 8% load (on total weight: 12 g oil + 138 g wax), 100 candles a day demonstrated, 15 extras, 5% rejects, 2% breakage, 2% late defects, 1% heel, 2 set-up and 3 tail days, the one-remake-day and one-lost-day allowances, the stress-test delays and the 6-day week with day 1 a Monday are labelled worked examples; the 10–15% band and the 72-hour set are judgements. Wax and oil ceilings are as the pages state (Chunks up to 13%; Japanese Cherry Blossom 6–13% for candles): formulation limits, not regulatory ones; the jar page's "Safe for hot pour up to 85°C" is a pour limit. Costs are materials only and exclude labels, cartons, labour, freight, GST and marketing. Diwali 8 November 2026 is a calendar fact; the November–February wedding season is a commonly cited pattern.
