Scented Jar Candle Inspection in India

Scented jar and container candle inspection in India

A scented candle inspection checks that the wick is centred, upright and firmly fixed, burns a sample to a full melt pool to look for tunnelling, high flames and soot, compares cold and hot fragrance with the master, and checks the wax surface, fill weight, jar, lid and warning labels. Most jar-candle returns start with the wick, not the wax.

Typical materials

Paraffin, soy, rapeseed, coconut or blended waxes; fragrance oil; cotton or wood wicks on metal tabs; glass, ceramic, tin or concrete containers

Where it's made in India

No export cluster is verified, so we name none; jars and fragrance are usually bought in

Key rules

US: lead-wick ban (16 CFR 1500.17), ASTM F2417, F2058, F2179; EU: GPSR, CLP, EN 15493, 15494, 15426

Typical AQL

General II; 0 critical, 2.5 major, 4.0 minor; burn screen on a special sample

How scented container candles are made

Wax is melted, fragrance oil and any dye are stirred in at a set temperature, and the mix is poured into jars that already have a wick glued to the base on a metal tab. Wick bars or clips hold the wick upright while the wax sets. After cooling, sinkholes are topped up or smoothed with a heat gun, the candle is left to cure, and the lid and labels go on.

Each choice affects the burn. A wick that is too small for the jar tunnels down the middle; one that is too large gives a tall, sooty flame and overheats the glass. Fragrance load and the type of wax change how the wick behaves, so a wick that worked in the approved sample may not work after the supplier changes wax or fragrance.

Containers are usually bought from glass and ceramic makers. Candle exports are not small: India exported US$74.8 million of candles (HS 3406) in 2023, half to the US and about a fifth to the UK, according to TrendEconomy's UN Comtrade data.

What we check on scented candles

Check	How it is checked	What fails
Wick position	Measured from the jar wall in two directions; checked upright	Wick off-centre beyond tolerance, leaning, buried or too short to light
Wick tab bond	Light pull on the wick of an unpoured jar or a reject; tab position seen through clear glass	Tab lifts from the base or sits off-centre
Burn screen	A set of candles burned in still air for the time your plan sets, usually until the melt pool reaches the wall	Tunnelling, flame above the agreed height, black smoke, wick mushrooming, flame touching the glass
End of burn	Where agreed, one candle burned down to the base	Flame does not go out at the tab, glass cracks, base too hot to touch
Fragrance	Cold and lit, against the master, by variant	Weak, different or mislabelled fragrance
Wax surface and adhesion	Top surface and walls checked through the glass	Sinkholes, cracks, rough tops, wet-looking patches where wax has pulled from the glass, beyond the sample
Fill and weight	Net weight on a calibrated scale; fill line	Below declared weight, uneven fill across a set
Container and lid	Glass checked for chips, cracks, seeds and thin bases; lid fit	Chipped rims, cracks, loose or tight lids, rust on tins
Labels	Warning label, allergen and hazard statements, net weight, batch code and origin against artwork	Missing or wrong warning, wrong language, missing batch code

Common scented jar and container candle defects and how they are classed

Defect	Typical cause	Class
Glass cracks during the burn	Poorly annealed jar, wick too large, flame on the wall	Critical
Flame touching the container wall	Off-centre wick	Critical
Metal-cored wick without lead conformity	Unknown wick source	Critical for the US until proven
Missing fire-safety warning	Label skipped or wrong artwork	Major
Tunnelling or heavy soot in the burn screen	Wick size wrong for wax, fragrance or jar	Major
Weak or wrong fragrance	Fragrance load cut, wrong oil, batch mix-up	Major
Short weight	Underfill	Major
Frosting or wet spots on soy wax	Natural wax crystallising, temperature changes	Minor if within the sample

Your defect list decides the final class. Agree in advance whether frosting on natural waxes is acceptable, as it is cosmetic and common.

Market rules for container candles

US lead wicks. Under 16 CFR 1500.17(a)(13), candles with metal-cored wicks made or imported from 15 October 2003 are banned unless the core has no more than 0.06% lead by weight and the outer packaging says "Conforms to 16 CFR 1500.17(a)(13)". Most jar candles use cotton or wood wicks, but check the wick specification.
US standards. ASTM F2417 covers candle fire safety, ASTM F2058 the fire-safety label, and ASTM F2179 the annealing and thermal-shock performance of soda-lime glass made as candle containers. They are voluntary; many retailers ask for lab reports.
EU. Candles must be safe under the GPSR. EN 15493 sets fire-safety requirements, EN 15494 the safety labels and EN 15426 sooting behaviour. Scented candles are commonly labelled under CLP because their fragrance can contain skin sensitisers, which can bring hazard labels or an allergen statement; the classification comes from the fragrance supplier's data.
California. Some buyers ask for a Proposition 65 assessment of the wax, fragrance and container decoration.

Lab tests go to an accredited lab through lab testing coordination. If you sell the candle with a holder or lid accessory, see candle holder inspection.

Packing, heat and your purchase order

Heat is the main transit risk. In a hot container, fragrance can sweat to the surface, soft waxes can slump and lids can stick. Glass jars need dividers or moulded pulp so they do not touch, and the inspector checks that a packed carton survives a short drop without chipped rims. Candles should cure before packing for the time your supplier specifies, and the inspector notes the pour date.

Wax type, fragrance name and load, dye, and wick type and size.
Jar drawing, glass supplier and any thermal-shock test report.
Burn screen: how long, flame height limit and pass rules.
Net weight, fill line and lid type.
Warning and hazard label artwork per market.
Curing time, packing method and a carton drop test.

Frequently asked questions

Why does my candle tunnel?

The wick is too small for the jar diameter, or the wax and fragrance changed after the sample was approved. A first burn that is too short also starts a tunnel. The burn screen at inspection shows whether the melt pool reaches the wall in the agreed time.

Do you burn every candle?

No. Burned candles cannot be sold. A small set per fragrance and size is burned, agreed in the plan, and the rest of the sample is checked without lighting.

Is frosting on soy candles a defect?

Usually not. Frosting is a white crystal pattern that natural waxes form over time. It is cosmetic, and buyers usually accept it if it is within the approved sample. Agree it in your specification.

How do you check for lead in wicks?

The inspector checks whether wicks have a metal core and reviews the wick supplier's specification. If a wick has a metal core, lead content is measured by a lab.

Do scented candles need CLP labels in the EU?

Often yes, because fragrance oils contain sensitising substances. Whether a candle needs a pictogram, a hazard statement or only an allergen statement depends on the fragrance data. Your compliance adviser decides; we check the label on the goods.
