I Make Candles in Pune but Ship Across India — Should My Soy Wax Be Tested at Temperatures Higher than My Normal Workshop Temperature?
Share
Where do the temperatures come from? From a min/max thermometer or logger inside real parcels on your routes — not weather apps. See the route log.
Do I test every city? No. Band routes and test the worst one with margins: 24 candles instead of 42 for an example 6 routes.
What does it cost? ₹7,007.00 in CSI materials for Chunks vs CSI 468 with Jasmine. See the kit.
Yes — your workshop is the coolest stop your candle will see
The short answer is yes, and the more useful answer is how much higher and where the numbers come from. Your workshop is where the candle is made, cured and packed. It is also, almost always, the most controlled place in the candle's life: shaded, ventilated, perhaps air-conditioned, and checked by you every day. The moment a parcel leaves Pune it enters places you do not control — vans, hubs, loading bays, doorsteps — on routes that run into very different regional climates. Testing only at workshop temperature proves that the candle survives your workshop. You already knew that.
How much higher is where most heat tests go wrong. A temperature picked from a weather app describes the air outside, not the inside of a closed carton in a van. A temperature picked because it sounds safely high can push every wax into failure and tell you nothing. The way through is a ladder built from your own logs: the workshop at the bottom, the logged peaks of your actual routes above it, the worst logged route as the main test arm, and two margin arms above that — one hotter, one longer — that you choose and write down before you start. Every rung but the margins comes from a min/max thermometer or temperature data logger that travelled inside a real parcel (neither is a CSI item; buy one locally).
This page uses Luxury Soy Wax Chunks and Premium Coconut Soy Wax CSI 468 as the two waxes. Both product pages state a fragrance ceiling of up to 13%, and CSI 468's page also states a melting point of 50–53°C and a pour temperature of 58–60°C. Chunks' page gives no melting point. That difference in what is published is not a difference in how they behave in a parcel, and this page draws no conclusion from it. The ladder is how you find out.
Building the ladder: one logger, several routes
You do not need a logger in every parcel for a year. You need enough logged trips to know which of your routes is hardest, and roughly how hard. If you ship from Pune to several regions, the routes will differ in distance, days in transit, hub stops and destination climate. General knowledge says north-west India's May–June heat and long hauls are hard, and that coastal routes add humidity — but your carrier, your dispatch day and your packing decide the number inside your box. Log it.
| Route (yours) | Days in transit | Peak inside parcel | Hours above workshop temperature | Warm–cool cycles | Rank |
|---|---|---|---|---|---|
| Pune → local / same city | ___ | ___°C | ___ h | ___ | ___ |
| Pune → Mumbai | ___ | ___°C | ___ h | ___ | ___ |
| Pune → Delhi | ___ | ___°C | ___ h | ___ | ___ |
| Pune → Jaipur / Rajasthan | ___ | ___°C | ___ h | ___ | ___ |
| Pune → Chennai | ___ | ___°C | ___ h | ___ | ___ |
| Pune → (your sixth route) | ___ | ___°C | ___ h | ___ | ___ |
| Worst logged route → M arm | ___°C | ___ h | ___ | 1 |
Rank routes by the combination of peak and hours above workshop temperature, not by peak alone. A route that peaks a little lower but stays warm for two days can be harder on a candle than a short spike. That is why the ladder has two margin arms: one that raises the temperature, one that stretches the time. Rajasthan summer approval turns the duration margin into repeated day–night cycles for long hauls, and Chennai and Mumbai humidity covers what to watch on the coastal routes that a temperature log alone will miss.
The four arms and what each one proves
| Arm | Temperature | Duration | What a pass proves | What it does not prove |
|---|---|---|---|---|
| W · Workshop | Your workshop, logged | Whole test | The reference — your approved candle | Anything about shipping |
| M · Worst logged route | Peak inside your worst parcel | Its logged hours | The candle came through your hardest route, as logged | A hotter-than-logged day |
| HT · Temperature margin | M + a margin you choose (write it down) | Same hours as M | Headroom for a hotter day | A longer trip |
| HD · Duration margin | Same as M | A multiple of M's hours you choose | Headroom for a delayed parcel | A hotter day |
| Per wax | 12 candles | 24 for two waxes |
Why both margins? Because they catch different failures. A candle can tolerate a short spike and still sweat after a long warm soak, or ride out a long, moderate trip and still slump in a sharp one. A wax that passes M but fails only HD is telling you that parcel delays are your real risk — a packing and dispatch-day question as much as a wax question. A wax that passes M and HD but fails HT is telling you that a freak-hot day is the risk. Simulating hot courier conditions at home covers how to hold a chosen temperature for a chosen time without a kitchen oven or a heater aimed at the candles — both are uneven and a fire risk with fragrance oil.
Scoring sheet: four arms, one twin
One sheet per wax. Compare every exposed arm with W only, and write the pass rules before the first candle goes into heat. CSI publishes no numeric flame-height or jar-temperature limit; the burn rule is no worse than the W twin on every safety line, within your jar supplier's guidance and the candle fire-safety standard you work to (ASTM F2417 is a commonly cited US standard).
| Line | W | M | HT | HD | Pass rule |
|---|---|---|---|---|---|
| Condition received | ___°C | ___°C, ___ h | ___°C, ___ h | ___°C, ___ h | Record |
| Surface 0–3 (8%) | ___ | ___ | ___ | ___ | No worse than W |
| Dent change, mm (unscented / 8%) | ___ / ___ | ___ / ___ | ___ / ___ | ___ / ___ | Within your tolerance by 24 h |
| Blot 0–3 (unscented / 8%) | ___ / ___ | ___ / ___ | ___ / ___ | ___ / ___ | 8% no wetter than unscented |
| Glass contact, wick lean | ___ | ___ | ___ | ___ | Within standard |
| Burn vs W: flame, soot, jar | ref | ___ | ___ | ___ | Safety: no worse than W |
The priced test kit — and why banding routes saves candles
CSI's load convention: oil = 200 g × load. Each wax needs 2,272 g for twelve candles (2,385.6 g with a 5% pour-loss allowance, a working assumption); the sixteen 8% candles need 256 g of Jasmine, 268.8 g with the allowance.
| Item | Need | Buy | Price |
|---|---|---|---|
| Luxury Soy Wax Chunks | 2,385.6 g | 5 × 500 g | ₹1,495.00 |
| Premium Coconut Soy Wax CSI 468 | 2,385.6 g | 2 × 1 kg + 1 × 500 g | ₹1,625.00 |
| Jasmine Fragrance Oil | 268.8 g | 3 × 100 g | ₹1,290.00 |
| Eco Candle Wicks Thin C1 | 24 + 2 spare | 1 × 20-pack + 1 × 10-pack | ₹177.00 |
| White Matte Glass Jar | 24 jars | 5 × 5-pack | ₹1,770.00 |
| Premium Packing Tissue Paper (blot test) | 1 sheet per candle per check | 1 × 100 sheets | ₹650.00 |
| Kit total (loggers not included) | ₹7,007.00 |
Testing every route as its own arm is tempting and expensive. With an example 6 destination routes, a separate arm per route plus the workshop would need 42 candles for two waxes — about ₹12,262.25 at this kit's ₹291.96 per test candle — against 24 candles for the banded ladder. The ladder works because a candle that passes your worst logged route with margins to spare has, by construction, been tested harder than every milder route. You only add a route-specific arm when a route is different in kind, such as humidity — 5427.

Cost per candle, and the order that follows the ladder
At production packs (Chunks 5 kg, CSI 468 10 kg, Jasmine 1 kg, ₹5.90 wick, ₹70.80 jar; labour, packaging, freight and GST excluded) a 200 g candle at 8% costs ₹249.68 in Chunks (₹110.22 of wax) and ₹256.68 in CSI 468 (₹117.21 of wax). The ₹6.99 difference is wax price only — ₹62.77 of Jasmine, the wick and the jar are the same in both.
| Item | Need | Buy | Price |
|---|---|---|---|
| Chunks (if it passes) | 57,960 g | 11 × 5 kg + 3 × 1 kg | ₹34,742.00 |
| CSI 468 (if it passes) | 57,960 g | 5 × 10 kg + 1 × 5 kg + 3 × 1 kg | ₹36,985.00 |
| Jasmine (either wax) | 5,040 g | 10 × 500 g + 1 × 50 g | ₹19,840.00 |
Two buying notes. Chunks is cheaper in 5 kg bags than in 10 kg bags (two 5 kg bags cost ₹9.00 less than one 10 kg), so the month's order is built from 5 kg bags. CSI 468's per-kilo rate is the same at 5 kg and 10 kg (₹637.00), so the bag size is a handling choice. Neither wax has a published volume discount; larger quantities are quoted on WhatsApp. Jasmine's 1 kg bottle is ₹3.92 a gram against ₹4.30 at 100 g — one of the oils where the 1 kg size is genuinely cheaper per gram, which is rare on CSI's listed catalogue.
The decision rule
| Result | Decision | Purchase |
|---|---|---|
| Passes M, HT and HD | Approve for all logged routes | 10 kg pilot, then the monthly order above |
| Passes M and HT, fails HD | Approve with a dispatch rule: no parcels that can sit over a weekend in the hottest months | 10 kg pilot; revisit packing — 5434 |
| Passes M and HD, fails HT | Approve with a seasonal rule for the worst route | 10 kg pilot; summer vs year-round formula |
| Passes M only | Approve for milder routes only; re-test the worst route at a lower load | Load ladder before buying more |
| Fails M | Do not ship that formula on that route | No bulk order — 5422 or 5430 |
If both waxes reach the same row, the cheaper one per candle wins. If they reach different rows, the higher row wins unless the cost difference outweighs the restriction you would have to accept. The hub shows the same logic applied to a single route and a 100 kg order, and the full qualification adds warehouse storage and customer use.
CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished candles. We publish no heat-survival data for any of our waxes, and the one published melting point in our soy range (CSI 468's 50–53°C) is a pour-planning fact, not a shipping verdict. This page is written so that the cheaper wax wins whenever both pass.
Every wax price is CSI live pricing, re-checked 1 October 2026; Jasmine prices are from the 24 September 2026 pull; wick, jar and tissue prices are as verified on 10 September and 24–25 September 2026. Candle splits, per-candle costs, banding comparisons and pack rounding are arithmetic, shown to two decimals. Product-page statements are attributed to CSI's product pages.

Non-price figures and assumptions: CSI convention: load is a share of the finished candle (200 g at 8% = 16 g oil + 184 g wax). CSI publishes no heat-survival, softening or sweating data for any wax. Route temperatures are the reader's own logged readings; chamber, closed-car and cycle conditions are labelled example test conditions, not specifications or claims that any wax survives them. Margins, arms, candle counts, six-route example, 300-candle month, per-test-candle cost and 5% pour loss are labelled working practices and examples. CSI publishes no flame-height or jar-temperature limits; ASTM F2417 is named only as a commonly cited standard. Material costs exclude labour, packaging, freight and GST.
