What exactly has to appear on a candle label before I can legally sell it at a market?

A candle sold in the United States carries two separate sets of label copy, and they come from two different places. The first set is federal consumer packaging law: the Fair Packaging and Labeling Act requires a statement of identity, a net quantity of contents, and the name and place of business of the responsible party. The second set is the fire safety warning built on ASTM F2058, which is a voluntary consensus standard that has become the practical expectation of every insurer, every wholesale buyer and every market organizer you will meet.

So the short answer is: what the candle is, how much of it there is, who is responsible for it, and a warning block telling the buyer to burn it within sight, keep it away from anything flammable and keep it away from children and pets. If your California customers matter, a Proposition 65 assessment sits on top of that.

None of it is difficult. It is just unforgiving about details, and the details are the part that gets missed when you are printing labels at eleven at night before a Saturday market.

The three FPLA panels: identity, net quantity, responsible party

Federal packaging law thinks about your label in terms of panels, not stickers. The principal display panel is the surface the buyer is most likely to see when the product sits on a shelf. For a tin, that is usually the lid. For a straight sided glass jar, it is the front curve of the wrap.

Two things belong on that principal display panel.

• The statement of identity. What the product actually is, in plain words. "Soy wax candle" is an identity. "Cedar and Smoke" is a fragrance name, not an identity, so it cannot do this job alone.
• The net quantity of contents. The weight of the wax, not the weight of the jar, and not the fill capacity of the vessel.

The third element, the name and place of business of the manufacturer, packer or distributor, can sit on an information panel instead. That is any other reasonably visible surface. If you use a business address rather than a home address, you still need a real street address or a listing under that business name in a current directory. A bare Instagram handle does not satisfy this.

What "responsible party" means when you did not pour it

If a contract pourer makes your candles and you sell them under your own brand, you are the distributor. Your name goes on the label, qualified so the buyer knows the relationship: "Distributed by" or "Manufactured for" before your business name. Only say "Manufactured by" if you poured it.

How net weight is expressed in both US and metric units

The net quantity has to appear in both inch and pound units and metric units. For candles that means ounces and grams, in that order, on the principal display panel, in the bottom thirty percent of that panel, and separated from other print.

The number is the wax, plus fragrance and dye, that you actually poured. It is not the vessel capacity that your supplier lists. An eight ounce tin does not hold eight ounces of wax. Fill an eight ounce tin to a normal fill line and you will typically land nearer six and a half ounces of soy. If you label that as 8 oz you have misstated net quantity, which is the single most common labeling error in this trade.

Get the figure from your own scale. Weigh the empty vessel, weigh it after cure, subtract. Do it across a full batch and take the low end of the spread as your declared weight rather than the average, because the declaration is a minimum, not a target.

Rounding and the metric conversion

One ounce avoirdupois is 28.3495 grams. A 6.5 oz fill is 184.27 grams, which you would declare as 184 g. Round the metric figure down rather than up, for the same reason: you want the printed number to be one every jar in the batch can meet.

The ASTM F2058 fire safety label and where it belongs

ASTM F2058 is the standard practice for candle fire safety labeling. It describes a warning block with four parts working together.

1. A signal word, in practice the word WARNING, with a pictogram of a burning candle inside a prohibition or alert symbol.
2. Burn within sight.
3. Keep away from things that catch fire.
4. Keep away from children and pets.

Most makers add supporting instructions underneath: trim the wick to one quarter inch before each lighting, burn no more than four hours at a time, stop use when a half inch of wax remains, never move a burning candle, place on a heat resistant surface. Those instructions are what a product liability adjuster looks for when a claim lands, so they are worth the label real estate.

Why the warning goes on the container base or vessel wall

The warning has to survive the life of the candle and stay legible while the candle is burning. That rules out anything printed only on a box the buyer throws away, and it rules out a lid sticker on a jar whose lid gets set aside the first evening.

The base of the vessel is the usual home for it. It is permanently attached, it stays with the product, and it does not compete with your brand design. If the candle is a pillar or a taper with no base to speak of, the warning goes on a hang tag or wrap that the standard treats as the labeling of last resort, and you accept that some buyers will remove it.

Practical detail that catches people: heat and wax weeping will lift a paper label off a warm tin. If your base label is peeling off units in a customer's home, the warning is not on the product any more. Use a label stock rated for the surface and test one by burning a unit to the end.

State level additions and Proposition 65 for California buyers

California's Proposition 65 requires a warning before knowingly exposing a person to a listed chemical above the safe harbor level. It applies to businesses with ten or more employees, but the practical risk sits with sellers of every size, because online orders shipped into California are what draw private enforcement letters.

The route through it is documentary rather than creative. Ask each fragrance supplier for the Prop 65 statement that goes with the specific fragrance oil, by name and batch code, and keep it with the record for the batches you poured with that oil. Most reputable fragrance houses publish these. If a fragrance carries a listed chemical above threshold, the short form warning goes on the label, naming at least one chemical and the Prop 65 website.

A few states also regulate specific ingredient disclosures for consumer products. Those change, so the reliable habit is to re-request supplier documentation annually rather than to trust a PDF you downloaded three years ago.

Scent and fragrance claims that create liability

The words around the scent are where a candle quietly changes category. Describing a candle as relaxing is marketing. Describing it as relieving anxiety, easing headaches or purifying the air is a therapeutic or performance claim, and a claim like that can push the product toward drug or air treatment territory and out of your product liability policy's coverage.

Two other traps worth naming:

• "Essential oil" on a candle blended with fragrance oil. If the blend is mostly synthetic aroma chemicals, say fragrance. Mixed blends should say so.
• "Non toxic", "clean burning", "eco friendly". These are substantiation claims. If you cannot produce the testing behind them, do not print them.

A label proof checklist before you send a print run

Run every proof against this before the order goes out. A print run of a thousand wrong labels is a real cost, and the errors are always small.

Check	What passes
Identity on front	Names the product type, not only the scent name
Net weight	Ounces and grams, bottom third of front panel, weighed not assumed
Responsible party	Business name plus street address, with the correct qualifier
Warning block	Signal word, pictogram, three core statements, legible size
Warning placement	Base or vessel wall, stays attached through a full burn
Prop 65	Supplier statement on file for this fragrance lot, warning added if needed
Claims	No therapeutic, no unsupported safety or environmental language
Batch code	Present, and traceable back to a pour record

That last row is not a legal requirement, and it is the one that saves you. A batch code turns a customer complaint into a ten minute investigation instead of a guess about which fragrance lot was in the jar.

Where this gets easier

The reason candle labels go wrong is rarely ignorance of the rules. It is that the label lives in a design file and the true fill weight lives in a notebook, and the two drift apart across a season of new scents and new vessels.

WickAndWax closes that gap by generating the label from the batch record itself. You log the pour, the fill weight, the fragrance lot and the cure date, and the label comes out with the identity, the dual unit net weight, the responsible party line, the warning block and a batch code that ties back to that exact pour. When a buyer emails about a jar they bought in November, you look up the code and see the record.
