Agarwood Incense Cones: A Buyer's Guide to Cones, Backflow Cones, Sticks and Coils

Agarwood incense cones are small, self-burning cones pressed from agarwood powder, a binder and usually some filler. You light the tip, blow out the flame and the cone smoulders down to its base.

The numbers explain the price. According to Liu et al. (2013), only about 10% of Aquilaria trees produce agarwood without human help, so most supply today comes from induced, cultivated trees.^[4]

They belong to the family of combustible incense, alongside sticks and coils. In other words, the cone carries its own fuel, so no charcoal or electric burner is needed. That separates cones from oud wood chips and bakhoor, which are heated from below.

For a shopper, the appeal is simplicity. A cone needs only a heat-proof dish, it gives a concentrated burst of scent, and it leaves no bamboo core behind. For a retailer, the appeal is a different shelf position from sticks, often at a different price point.

We do not list cones as a stock product. Our wholesale range covers agarwood powder, coreless and cored sticks, Japanese-style koh incense, bakhoor and chips. Cones are therefore a format you discuss with a supplier, and this guide covers what that discussion should include.

How a Cone Is Formed

The basic method is old and simple. Makers mix dry powders, add water until the mass behaves like stiff clay, then press or roll it into a cone. The cones dry slowly before packing.

Small workshops shape cones by hand or with hand-filled moulds. Larger makers use pressing machines with multi-cavity moulds, which keeps the size and weight consistent from cone to cone.

Drying matters more than most buyers expect, and we would ask about it first. A cone that dries too fast can crack, while one packed too wet can grow mould in transit. Ask any cone supplier how they dry and how they check moisture before packing.

Shape decides how much fuel burns at once. A cone starts narrow and widens towards the base, so the burning area grows as it burns down. Therefore cones give stronger scent per minute than a stick of similar weight, but they finish sooner.

Sticks give the most even burn and the widest range of formats. Our own agarwood incense sticks in cored and coreless styles cover daily-use and gift lines. We explain stick formats, kyara-grade sticks and quality checks in our guide to agarwood incense sticks.

Coils, to our mind, sit at the other end. They are built for long sessions in temples and large rooms, where a cone would finish too fast. However, coils need careful packing, and many retail buyers outside East Asia never stock them.

A backflow cone is a hollow cone designed to make smoke flow downwards. It sits on a special burner, often shaped like a mountain, a lotus or a small waterfall, and the smoke runs over it like mist.

Why the Smoke Falls

The hole in the base opens into a channel that runs up inside the cone. As the cone burns down, part of the smoke is drawn into that channel and cools as it passes through. Cooler, denser smoke then sinks out of the base and spills over the burner.

We should stress that the effect only works in still air. A fan, an open window or air conditioning will break the stream and lift the smoke instead. That is worth printing on a pack, because otherwise a customer may assume the cone is faulty.

The effect also depends on smoke density. A formula that burns very cleanly, with little visible smoke, gives a weak backflow. For that reason, backflow formulas are often built for heavier smoke than standard cones.

Trade-offs for Retailers

Backflow oud incense cones sell on looks. They film well, they suit gift sets with a burner, and they give shops a reason to sell accessories. Moreover, the burner itself becomes a repeat-purchase driver for refill cones.

The trade-off, as we see it, is the scent. A cone tuned for dense smoke is not always the cone that shows agarwood at its best. Fine agarwood character usually comes through better in a gently heated chip or a well-made stick than in heavy smoke.

So we suggest deciding early what the line is for. If it is a display and gift product, backflow makes sense. If it is a fragrance product for oud lovers, a standard cone or a stick may serve the customer better.

Every cone is a recipe of three parts: an aromatic material, a binder that holds the shape, and fuel that keeps it burning. In oud incense cones, the aromatic part is agarwood powder, sometimes with added oils or other aromatics.

Agarwood itself is resin-loaded Aquilaria wood. Its scent comes from sesquiterpenes and 2-(2-phenylethyl)chromones that form in the resinated wood, and heat releases them into the air.^[1] Pale, unresinated wood contributes bulk and burn, but very little oud character.

Binders: Makko, Joss Powder and Gums

The binder decides how a cone burns as much as how it holds together. Japanese-style incense traditionally uses makko, a powder from the bark of the tabu-no-ki tree, which binds and burns with little scent of its own.^[2]

Chinese and South Asian makers often use joss powder, a sticky bark powder, for the same job. Natural gums such as gum arabic or guar also appear, usually in small amounts, because too much gum makes a cone hard to light.

Some lower-cost cones add charcoal powder, plain wood flour or a burn aid so that they stay lit. Those additives are not wrong in themselves. However, they change the smoke, and a buyer should know they are there.

How Much Agarwood Is in a Cone?

There is no industry standard for agarwood content in cones. One maker's "oud cone" may be mostly agarwood powder; another may hold a little agarwood plus a synthetic oud fragrance oil.

No self-burning cone can be pure agarwood, because it needs a binder to hold its shape. Therefore the honest questions are how much agarwood the formula holds, what grade of powder it uses, and whether any fragrance oil is added on top.

In our view, grade matters as much as percentage. Powder milled from entry-grade D or C material burns with a lighter, woodier note, while powder from better-resinated wood smells deeper. Our agarwood powder for incense making starts from $10.30 per 50 g, and price rises with the grade of wood it is milled from.

We cover mesh size, makko blends and other powder applications in our agarwood powder uses guide. For cones specifically, a fine, even mesh presses more cleanly and burns more evenly than coarse powder.

Burn time varies, and in our view any fixed number on a pack should come from testing that exact cone. Size, density, binder, moisture and airflow all change how long a cone lasts.

As a general pattern, a cone burns faster than a stick of similar weight, because its base is wider. A coil of similar weight lasts longest, since it burns a thin strand over a long path.

What Changes Burn Time

• Size and weight: a taller, heavier cone holds more fuel and lasts longer.
• Density: firmly pressed cones burn slower than loose ones, but very dense cones can go out.
• Binder and fuel: makko and burn aids keep a cone lit; gums and heavy resins slow it.
• Moisture: damp cones light poorly and smoulder unevenly; humid storage makes this worse.
• Airflow: a draught speeds burning and, for backflow cones, breaks the smoke stream.
• Backflow channel: the hollow core removes material, so backflow cones are often shorter-burning than solid cones of the same size.

For private-label work, ask the supplier to burn-test several cones from each batch in still air and record the range. Then print a range, not a single number, and keep the test notes on file.

We would also check the ending. A good cone burns down to the base. A cone that dies halfway usually points to uneven density or too much moisture, and customers notice it at once.

Storing Cones and Burning Them Safely

Cones keep best in a sealed container away from damp and heat, because humidity makes them hard to light and dulls the scent. Retail packs with an inner bag or tin last longer on the shelf.

Burn cones on a heat-proof dish or a matching backflow burner, never directly on wood or fabric. Backflow cones need a hollow base and a burner made for them. Keep the room ventilated, as with any incense.

Cones pack more efficiently than sticks, because they are short and solid. However, they still need moisture protection. A sealed inner bag or a lined tin protects both scent and lighting quality, especially in humid markets.

Labels should state the main ingredients, safe-use guidance and, for backflow cones, the still-air note. Your market may have its own rules on labelling of combustible incense, so confirm them with your importer or regulator.

MOQ Reality for a Cone Line

Cone MOQs depend on the maker, the mould and whether the formula is custom, so we quote them per project. A custom mould, a custom scent blend or printed packaging will usually raise the first order size.

Our own published minimums give a useful reference point for adjacent lines. Bakhoor incense sticks and our other stick lines run from $2.35–$5.89 per box with an MOQ of 1 kg. Japanese koh incense starts from $6/g with an MOQ of 100 g, and oud wood chips start from $0.24/g with an MOQ of 100 g.

If you are building a cone line from our materials, the starting point is usually powder and an existing incense order. You can test our powder grades and our Japanese-style koh incense as reference scents before briefing a cone maker.

A gently heated chip is the best benchmark for what agarwood should smell like. Our guide to burning oud wood chips explains how to heat chips without scorching them, which makes the comparison fair.

Paid samples from us start from 100 g of plantation oud wood chips graded D to AAA or 1 g of oil. Samples are non-refundable, and we reply to enquiries within 4 business hours, Monday to Saturday, 9:00–18:00 China time, through our wholesale contact page.

Sometimes. All Aquilaria species have been listed in CITES Appendix II since 2004, and the listing covers many agarwood products, not only raw wood.^[3]

• Annotation #14: the listing carries an annotation that exempts some finished products packaged for retail. Check the current annotation text before you plan a shipment, because it can change at CITES meetings.
• Bulk powder and chips: powder and wood sold for further processing are not retail-packaged, so they may need an export permit.
• Bulk cones for repacking: unbranded cones in bulk bags may be treated differently from cones in retail tins. Confirm with the authorities before you choose your pack format.
• Our shipments: every wholesale shipment from us travels with a grading note or certificate, plus a CITES Appendix II export permit wherever one is required.
• Your side: importing countries can add their own rules. EU buyers should read our notes on importing oud incense into Europe.
