# Sourcing candles home fragrance China: wax, burn tests, and packing
Sourcing candles home fragrance China is one of the more forgiving product categories to import, right up until it is not. Candles look simple: wax, wick, scent, glass. But the difference between a candle that burns cleanly for forty hours and one that tunnels, smokes, or cracks its glass is entirely in manufacturing discipline, and you cannot see that discipline in a product photo. The importers who do well in this category test the burn, specify the wax, and pack for transit. The ones who struggle buy on scent and price and learn about wick sizing from customer reviews.
This guide covers the sourcing candles home fragrance China checkpoints that matter: wax and fragrance load, burn testing, EU labeling rules, glass quality, leak-proof packing, and how to vet a candle factory before you commit to a container.
Wax and fragrance load: what you are actually buying
Every candle is a fuel system, and the wax is the fuel. The common waxes in Chinese production are paraffin, soy wax, and paraffin-soy blends, with beeswax and other waxes at the premium end. Each behaves differently: melt point, scent throw, burn time, and how it takes color all change with the wax. When you are sourcing candles home fragrance China, the first specification to pin down is the wax type and the blend ratio, in writing, because wax is the easiest place for a factory to substitute quietly.
Fragrance load is the second specification, and it is the one buyers misunderstand most. Fragrance load is the percentage of fragrance oil in the wax, and more is not automatically better. Too little and the candle has no throw. Too much and the fragrance oil can seep, sweat, or destabilize the burn, and some oils at high loads cause sooting. A competent factory will recommend a load for each wax and fragrance combination rather than letting you pick a number. Ask what load they recommend for your chosen scent and why. That conversation is a standard part of sourcing candles home fragrance China done well. The quality of the answer tells you how much they know.
Scent itself deserves a sampling discipline. Fragrance oils vary between batches, and the scent of the sample you approve should match the scent of production. Keep a retained sample from the approved batch, sealed and dated, and compare production samples against it. Noses differ, so do this comparison with two or three people and write down the verdict. In sourcing candles home fragrance China, scent drift between sample and production is one of the most common complaints, and a retained sample is the only objective reference you have.
Burn tests: the QC step that separates factories
Burn testing is the single most important quality step in sourcing candles home fragrance China, and it is the step most skipped by first-time buyers. A burn test means lighting the candle and burning it in cycles, typically a few hours at a time, and observing what happens: does the melt pool reach the edge, does the flame stay stable, does it soot, does the glass get dangerously hot, how many hours does it actually last.
Tunneling is the defect to watch for: the wick burns a hole down the center while wax builds up on the sides, wasting half the candle. Tunneling is a wick-sizing problem, and wick sizing is specific to the wax, the fragrance load, and the container diameter. Change any of those three and the wick needs re-testing. This is why a factory that says "we use the same wick for everything" is a factory to avoid.
Sooting is the second defect. A little soot on the first light is normal for some waxes. Heavy soot, black smoke, or soot marks climbing the glass indicate the wrong wick or too much fragrance oil. Customers notice soot immediately, and it photographs badly in reviews.
Build burn testing into your order in two places. First, require a burn test report or tested samples before production approval: the factory burns your exact wax, wick, fragrance, and container combination and reports the results. Second, pull production samples during inspection and spot-check the burn. It takes a few days of cycles, so start it early in the inspection window. Factories that do their own burn testing routinely will have a testing area with candles in various stages of burn. Ask to see it. Its absence tells you everything. Burn testing discipline is the clearest signal in sourcing candles home fragrance China factory vetting.
CLP/GHS labeling for the EU
If you sell candles or home fragrance in the EU, labeling is not optional decoration. Candles and fragrance products fall under classification, labeling, and packaging rules, and the EU uses the CLP framework aligned with GHS for hazardous substance classification. Fragrance oils can contain allergens and sensitizing substances, and above certain thresholds the product needs hazard pictograms, signal words, and precautionary statements on the label.
The practical consequence for sourcing candles home fragrance China is that you need the safety data for your fragrance oils and the classification of the finished product before you print labels. Your supplier should provide the safety data sheet for the fragrance oil used. Your label designer or regulatory consultant then determines what the finished candle label must carry. Do not let the factory design the compliance label from a template without this input. Templates guess. Guessing fails audits.
Check the current official source for the classification rules at the time of ordering. Allergen lists and thresholds get updated, and the version in force when your goods ship is what matters. This is a check-current-sources item, not a memorize-once item.
For the US, labeling has its own requirements, and California adds its fragrance-allergen disclosure expectations for certain products. The pattern is the same everywhere: know your market's rules before you approve artwork, because relabeling a container of candles at the destination is one of the most expensive fixes in this category.
Glass and container QC
The container is half the product in home fragrance. Glass jars, ceramic vessels, and tins all have their own failure modes, and glass QC deserves its own section in any sourcing candles home fragrance China plan.
Glass defects to check: bubbles and stones in the glass, uneven wall thickness, chips on the rim, and base instability. A jar that rocks on the table is a reject, not a minor defect, because a rocking candle is a tipping candle. Check the rim for a clean, even finish where the lid sits, because lids that do not seal let fragrance dissipate in the warehouse.
Heat stress is the specific risk for candle glass. The wrong glass, or glass with internal stresses, can crack under the heat of the burn. Ask the factory what glass specification it uses for candle containers and whether it has had heat-cracking issues. This is another question where the speed and specificity of the answer tells you what you need to know.
For ceramic vessels, check glaze consistency and the fit of the lid. For tins, check the seam and the lid fit. And for every container type, confirm that the container plus the wax fill plus the lid all came from the same specification you approved. Container substitution between sample and production is a quiet, common problem.
Leak-proof packing for fragrance products
Candles are solid. Reed diffusers, room sprays, and fragrance oils are not, and liquid home fragrance products need leak-proof packing or they will ruin everything they touch in transit. A single leaking diffuser bottle can soak through a carton and stain dozens of neighboring products. This is the packing problem that sourcing candles home fragrance China buyers underestimate most.
The packing specification for liquid fragrance products should include: individually sealed bottles (check the cap torque and seal), each bottle in a leak-proof bag or with absorbent protection, dividers between bottles, and cartons that can survive a leak without disintegrating. Test it: during inspection, invert sample bottles, shake them, and leave them upside down overnight. If the seal weeps, the packing plan is wrong.
For candles, the packing risks are different: glass breakage, wax damage from heat, and scent contamination. Specify dividers or individual boxes for glass candles, double-wall outer cartons, and container loading that keeps candle cartons away from heat sources and heavy goods stacked on top. Heat in transit can soften wax and shift wicks, so the shipping season matters. Summer containers need more care than winter ones, and this is worth discussing with your forwarder, not just your factory. Seasonal heat planning is an underrated part of sourcing candles home fragrance China logistics.
Vetting a candle factory
The right factory for sourcing candles home fragrance China answers questions about wax, wick, fragrance load, and burn testing without hesitation. The wrong factory sells you a scent and a price.
Start with the burn testing area. A factory that takes quality seriously has a dedicated space with candles at various stages of burn testing, labeled by batch. Ask to see burn test records for products similar to yours. Then ask about wick sourcing and sizing: who decides the wick size for a new product, and what happens when the wax or container changes. "The boss decides" is not a process. A testing-based answer is.
Ask about fragrance oil sourcing and batch control. Fragrance oils are the most variable input in candle making, and a factory that cannot tell you where its oils come from or how it handles batch variation will give you scent drift. Retained samples of approved fragrances, dated and sealed, are the mark of a controlled operation.
Check export-market experience with your market. A factory that already ships to the EU knows what CLP labeling requires and will have opinions about your label artwork. That experience saves you a relabeling disaster. Market-specific experience shortens every learning curve in sourcing candles home fragrance China. A factory that has only sold domestically can learn, but you will be the teacher, and teaching costs time.
Finally, separate factories from traders. Many candle "suppliers" are traders buying from small workshops, and the workshop is where the wax, wick, and burn discipline live. If you work through a trader, make sure the testing and specification requirements reach the actual producer, in writing.
Timelines: order seasonal fragrance months ahead
Home fragrance is seasonal, and the calendar is the strategy. Christmas, autumn, and spring collections all have ordering windows, and missing the window means missing the season. A realistic sourcing candles home fragrance China timeline for a seasonal collection: sampling and scent approval first, then burn testing of the approved combination, then production, then sea freight. Each stage takes weeks, and burn testing cannot be rushed because the candle has to actually burn.
Order seasonal goods months ahead of the selling season, and build buffer into every stage. Scent approval alone can take several rounds: the factory's version of "vanilla sandalwood" is rarely your version on the first try. Fragrance oil lead times add another wrinkle, since custom or unusual scents may need to be compounded to order.
For evergreen products the timeline is kinder, but the same sequence applies. The importers who struggle with sourcing candles home fragrance China timelines are almost always the ones who treated burn testing as optional and discovered the wick was wrong two weeks before the ship date.
Conclusion: sourcing candles home fragrance China rewards the testers
Sourcing candles home fragrance China is a forgiving category for buyers who test and an unforgiving one for buyers who do not. Specify the wax and fragrance load in writing, require burn testing of the exact combination you will sell, get the EU labeling right before artwork approval, check the glass, pack liquids against leaks, and vet the factory on its testing discipline rather than its price list. Do those things and candles become what they should be: a steady, repeatable product line.
FAQ: sourcing candles home fragrance China
### What is the most important quality test for candles?
The burn test. It checks the wick sizing, wax, fragrance load, and container as a system: melt pool, flame stability, sooting, glass heat, and actual burn time. No other test tells you whether the candle works.
### How do I prevent scent differences between sample and production?
Keep a sealed, dated retained sample of the approved fragrance batch and compare production against it with more than one nose. Put fragrance batch control in writing with the factory.
### Do candles need special labeling for the EU?
Yes. Fragrance products fall under CLP/GHS classification and labeling rules, and fragrance allergens above thresholds require specific label elements. Get the safety data for your fragrance oils and confirm the label requirements before approving artwork.
### What causes candle tunneling?
Wrong wick sizing for the wax, fragrance load, and container diameter. Any change to those three inputs means the wick needs re-testing.
### How should I pack reed diffusers for sea freight?
Individually sealed bottles with verified cap seals, leak-proof bags or absorbent protection per bottle, dividers, and sturdy cartons. Test seals by inverting samples overnight during inspection.
### When should I order Christmas candles?
Months before the season. Sampling, scent approval, burn testing, production, and freight each take weeks, and burn testing cannot be compressed. Work backward from your needed arrival date and add buffer.
