I’m Buying Jars, Wicks, Dyes and Moulds in Wholesale Quantities — Should Each Material Category Have Its Own Incoming QC Checklist?
Aktie
What goes in the shared header? Supplier and product, invoice number and date, quantity ordered versus received, packaging condition, status tag, and who checked it.
What if the supplier prints no lot number? Write the invoice number and delivery date on each inner pack. It lets you trace candles back to a delivery.
Which check matters most for jars? Damage. Chipped, cracked or hairline-marked glass never goes into production, so every jar gets a visual sort.
Why one generic checklist fails
Yes, each category needs its own checklist, but not its own paperwork system. The reason is simple: jars, wicks, dyes and moulds fail in completely different ways. A jar's worst failure is a safety one, a crack or chip that can fail under heat. A wick's worst failure only shows while burning. A dye's shows after the wax cures. A mould's shows after dozens of pours. A single generic form ends up either too vague to catch anything ("inspect for quality") or so long that nobody fills it in on a busy delivery day.
The practical design is two layers. A shared header, identical for every delivery, records what arrived and its status. Then a short category card, one per material type, lists only the checks that matter for that material, how many to look at, and what counts as a pass. The header gives you traceability across everything you buy; the cards give you checks that actually find problems.
None of this depends on supplier paperwork. CSI's product pages do not publish lot numbers, jar internal diameters or tolerances, wick dimensions or burn charts, dye concentration, or mould hardness and cycle life, and the same gaps are common across small-pack suppliers. Your cards are built around what you can see, measure and test yourself.
The shared header every delivery gets
Keep the header to one block at the top of each goods-in sheet. It should take under two minutes to fill in and it should be the same for jars as for moulds.
| Field | Example entry | Why it is there |
|---|---|---|
| Supplier and product | Clear salsa jar, 200 ml, golden lid | Identifies exactly what was ordered |
| Invoice number and date | From the GST invoice | Your trace key when no lot number is printed |
| Quantity ordered vs received | 100 ordered, 100 received | Shortages are found now, not mid-production |
| Outer packaging condition | Two cartons, one dented corner | Damaged cartons get checked first |
| Status tag | Quarantine / Approved / Conditional / Rejected | Nothing moves to production without one |
| Checked by and date | Initials | Accountability, and who to ask later |
The four category cards
Each card below is a suggested starting point. Sample sizes, limits and test lengths are yours to validate against your products and your history with each supplier; they are not standards and not CSI policy. The key idea is that each card is weighted towards that material's most serious failure.
| Material | Critical check | Other checks | Suggested sample | Release only after |
|---|---|---|---|---|
| Glass jars | Chips, cracks, hairline marks: remove any damaged piece | Rim smoothness, lid fit, internal diameter and height by caliper, bubbles in glass | Every jar looked at for damage; measure 10–20 from different cartons | Damage sort done and measurements inside your limits |
| Wicks | Tab firmly attached; wick straight and untangled | Count, length, obvious diameter change, coating look | 20 wicks from at least three bags or bundles | A test burn in your standard jar matches your approved wick |
| Dyes | Seal intact, no leaks, correct colour and pack size | Label units (gm or ml), settled or separated contents | One cured test puck per colour | Cured puck matches your retained colour standard |
| Moulds | Tears, holes, cavity damage, tacky surface | Number each unit, flex vs reference, cavity size | Every mould looked at; trial pour on the extremes | Trial pieces match your reference pieces |
Notice what the cards do not share. Jars get a full visual sort because a single cracked jar is a safety issue, not a statistic, and cracked or chipped glass never goes into production. Wicks and dyes are released on a functional test, because looking at them tells you little. Moulds get numbered, because they are used hundreds of times and one bad unit keeps causing problems until it is found.
Grade defects the same way on every card
Although the checks differ, the grading language should not. Use three levels on every card. Critical: a defect that could make a candle unsafe, such as a cracked jar or a wick tab that pulls away; any single one is removed and the lot is looked at more closely. Major: a defect that would change how the candle performs or looks to a customer, such as a dye that cures a shade off. Minor: a cosmetic point the customer will never see, such as a scuffed outer carton. Consistent grading lets you compare suppliers and deliveries across all four materials.
Worked example: one wholesale delivery, four cards
A delivery arrives with 100 clear 200 ml salsa jars at ₹2,950.00, 1,000 Eco Candle Wicks (Thin) at ₹5,900.00, a 100 g bottle of red liquid dye at ₹900.00, and 10 Sunflower silicone moulds at ₹295.00 each, which is 10 × ₹295.00 = ₹2,950.00. The delivery total is ₹2,950.00 + ₹5,900.00 + ₹900.00 + ₹2,950.00 = ₹12,700.00.
| Category | Value received | Check work | Held until |
|---|---|---|---|
| Jars | ₹2,950.00 (₹29.50 each) | Damage sort of all 100, measure 15 | Same day |
| Wicks | ₹5,900.00 (₹5.90 each) | Count and inspect 20 from three bundles, one test burn | Test burn complete |
| Dye | ₹900.00 (₹900.00 ÷ 100 = ₹9.00 per g) | Check seal and label, pour one test puck | Puck cured and compared |
| Moulds | ₹2,950.00 | Number all 10, flex check, trial pour two | Trial pieces compared |
The wicks are the most valuable line in this delivery and the least visible. At ₹5,900.00 ÷ 1,000 = ₹5.90 each, the whole bundle is released on the strength of one test burn and twenty wicks looked at closely. That is proportionate. Spending an hour on the dye bottle and five minutes on a thousand wicks would be the wrong way round.
Notice too that release timing differs. Jars can be approved the same afternoon. The dye waits for a cured puck, the wicks for a burn, the moulds for a trial. The header's status tag is what stops a quarantined bundle of wicks from walking onto the pouring bench while the jars from the same box are already approved.
Making four checklists workable in a small business
For questions a card cannot answer, such as whether a jar design has changed or whether a dye formula is the same, ask the supplier and write the answer on the card. For CSI materials, that is WhatsApp on +91 7397976926. Material that fails a card stays in quarantine whoever supplied it, CSI included, and it is not mixed into approved stock to hide the shortfall.

CSI already has guides that cover parts of this question. This page covers the goods-in check for the question above; these go deeper on the rest:

CANDLEMAKINGSUPPLIESINDIA supplies raw materials and production equipment, not finished candles. This guide separates general quality-control practice from what CSI's own product pages state, says plainly what CSI does not publish (lot numbers, certificates of analysis, tolerances), and labels every sample size, tolerance or retained quantity as a starting point for your own validation.
Prices are live CSI prices from September 2026; product pages are authoritative. Where a spec is not published — such as a lot number, a jar's internal diameter or a wick's burn rate — this guide says so rather than filling the gap.

Assumptions: Fragrance load is a percentage of total candle weight (200 g = 184 g wax + 16 g oil at 8%). CSI product pages do not publish lot numbers, certificates of analysis, tolerances, jar internal diameters, wick dimensions or mould hardness; where this guide needs them, it tells you to measure or ask. Sample sizes, tolerances, retained quantities, test lengths and acceptance rules are suggested starting points to validate, not standards or CSI policy. Hypothetical supplier prices are CSI prices adjusted by the stated percentage and labelled as such. Worked examples are illustrations. Prices and availability change — product pages are authoritative.
