Longan binchotan charcoal is a premium fruitwood white charcoal that VUTRUX carbonizes from longan (nhan) wood and exports FOB Hai Phong. Denser and more characterful than fast-grown species, longan produces a binchotan that burns long, hot and clean, with the fine grain and low ash that serious grill kitchens look for. This guide explains what sets longan apart, its typical specifications, how it burns, where it shines, and how to order it for export.
Key takeaways
- Longan binchotan is a dense fruitwood white charcoal with high fixed carbon (typically ~95%) and low ash (~3%).
- It delivers a long, stable, almost flameless burn with clean, subtle heat suited to premium grilling.
- Offered in Grade A and Grade B, round or split, in sizes from roughly 80 to 200 mm, packed in 10 kg cartons.
- One 20ft container carries about 9.6 MT net; samples are available before you commit to an order.
Why Longan Wood Makes Exceptional Binchotan
Longan (nhan) is a tropical fruit tree whose wood is prized for being hard, heavy and tight-grained. When trees are pruned or rotated out of orchards, that dense wood becomes an excellent feedstock for white charcoal. The same density that makes longan slow to season is what gives longan binchotan charcoal its weight-in-the-hand feel and its long burn.
Binchotan itself is a production method: hardwood is carbonized at high temperature, then raked out and smothered in a damp earth-and-ash mix so it cools fast and hard. If the category is new to you, start with our primer on what binchotan white charcoal is. Applied to longan, the method yields a charcoal that rings when tapped, holds its shape in the firebox and resists crumbling, so more of every carton reaches the grill as usable, full-length pieces.
Longan sits alongside lychee as one of the two classic fruitwoods in the Vietnamese binchotan tradition. The two are often compared, and you can read how the sister wood performs in our guide to lychee binchotan charcoal.
The Specifications of Longan Binchotan Charcoal
VUTRUX longan binchotan charcoal is tested by the independent laboratory Vinacontrol. The values below are typical ranges rather than fixed guarantees, and every shipment carries its own per-lot certificate of analysis.
| Property | Typical value | Why it matters |
|---|---|---|
| Fixed carbon | typically ~95% | More carbon means hotter, cleaner, longer-lasting heat. |
| Ash content | ~3% | Low ash keeps the grate clear and airflow open. |
| Moisture | ~3% | Dry charcoal lights faster and burns hotter. |
| Sulfur | ~0% | Near-zero sulfur means no acrid smell or off-flavors. |
| Calorific value | ~8,300 kcal/kg | High energy density for sustained service. |
Those figures describe a fuel that lights to a steady ember and then radiates heat for hours with minimal attention. There is little visible flame, almost no smoke and no harsh smell, so the charcoal never competes with the food. For a buyer, the practical payoff is consistency: batch after batch behaves the same way on the grill, which makes portioning fuel and planning service far easier.

How Longan Binchotan Burns
The defining quality of good binchotan is radiant, infrared heat rather than open flame, and dense fruitwood expresses that character especially well. Longan gives:
- Long burn time: heavy pieces hold usable heat for hours, so kitchens refuel less often than with lump charcoal.
- Stable temperature: even radiant output makes it easy to build hot and holding zones on one grill.
- A clean profile: near-zero sulfur and low volatiles mean minimal smoke, little flare-up and no acrid smell.
That combination lets a single cook manage many skewers at different stages without the fire surging or dying back. Because the pieces are so dense, partly burned coals can be smothered at the end of service and relit the next day, which meaningfully lowers cost per hour of cooking heat.
Buyers sometimes ask how longan compares with heavier oak binchotan. For the great majority of restaurant work the two are interchangeable in heat and burn time, with longan usually landing at a friendlier price. Where a kitchen needs the very hardest, longest-burning grade for marathon service, oak may still edge ahead, but for daily yakitori and robata longan is hard to beat on value.
Sizes, Grades and Packing
Longan binchotan is offered in two grades and a choice of formats so you can match it to your grills and your market:
- Grade A: the most uniform, straight and crack-free pieces, ideal for premium counters and retail.
- Grade B: sound, functional charcoal with a little more variation, a strong value for high-volume kitchens.
- Round or split: rounds burn slower and longer; splits light faster and pack more tightly.
Pieces typically range from about 80 mm to 200 mm, packed in 10 kg cartons with liners to control moisture and fines. Cartons stack cleanly, rotate easily and protect the product far better than loose bulk bags. Buyers building a full range often stock more than one size, larger pieces for longevity and smaller pieces to fill gaps and fine-tune heat.
Not sure which format to order? Share your grill type, bar spacing and service style, and VUTRUX can recommend a size blend and grade mix, then hold that specification across repeat orders so your results stay predictable.
Best Uses, Ordering and Export Terms
Longan binchotan is a natural fit for yakitori, robata and konro grilling, for steakhouses that sear over live coals, and for premium retail where a characterful fruitwood commands a better shelf price. If you are shaping a grill program, our guide to the best charcoal for restaurants puts longan in context with other fuels.
For export, a single 20ft container holds about 9.6 MT net (roughly 960 cartons of 10 kg), the practical minimum for a full-container order. VUTRUX ships to more than 40 markets on FOB, CIF or DDP terms with payment by T/T or L/C, and every lot comes with a COA, MSDS and phytosanitary certificate, plus EUDR due-diligence support for EU buyers. Vinacontrol self-heating tests conclude the charcoal is not IMDG Class 4.2, though carriers may still book it under UN 1361. Approve a sample first, then request a quote and a sample to confirm the grade suits your kitchen.
Storage and Getting Consistent Results
Longan binchotan reaches you dry and dense, and a little care in storage keeps it that way. Charcoal absorbs ambient moisture easily, and damp charcoal lights slowly and can spit, so treat storage as part of quality control:
- Store cartons off the floor in a cool, dry, ventilated area, away from rain and humidity.
- Keep liners sealed until use and rotate stock first-in, first-out.
- Handle gently to minimize breakage and fines.
Consistency also comes from how you buy. Approve a sample, tie the grade to a per-lot COA, and order against that specification every time so your chefs receive the same fire in every shipment. At the grill, smother and reserve unburned pieces at the end of service; longan's density means reclaimed coals relight readily and still burn hot, which improves your cost per hour of heat over a season.
Frequently asked questions
What is the difference between longan and lychee binchotan?
Both are dense fruitwood white charcoals that burn hot, long and clean, and for most restaurant work they perform very similarly. Longan tends to be exceptionally heavy and hard, while lychee is the other classic fruitwood in the Vietnamese tradition. Many kitchens choose based on availability, price and a slight preference in fire character.
Does longan binchotan add flavor to food?
Only subtly. Like all good binchotan, it burns almost smoke-free with near-zero sulfur, so it does not impose a heavy smoke flavor. Instead it delivers clean radiant heat that lets the ingredient and seasoning lead, which is exactly why it suits delicate poultry and seafood.
How long does longan binchotan charcoal burn?
A full load typically holds cooking heat for several hours, depending on piece size, airflow and how the coals are managed. Larger rounds burn longest; smaller or split pieces light faster but are consumed sooner. Partly burned pieces can be smothered and reused to stretch value.
What is the minimum order quantity?
Longan binchotan is normally ordered by the container, about 9.6 MT net in a 20ft, with mixed loads across grades and sizes often possible. Ask for a sample first to confirm the grade suits your kitchen, then discuss MOQ, packing and Incoterms for your market.
