Every week, our warehouse team in Foshan fields calls from buyers who just opened their rattan shipment and noticed an unexpected smell organic plant fibers ¹. Some describe it as earthy. Others say it reminds them of damp wood or even something sharper. The concern is always the same: is this normal, or did something go wrong?

Odors in natural rattan cane webbing come from four main sources: the plant’s inherent organic compounds, chemical treatments applied during processing, moisture-related mold or mildew growth, and environmental absorption during storage or transit. Most new-product smells are harmless and fade within one to four weeks with proper ventilation.

Understanding where these smells come from helps you tell the difference between a harmless new-product scent and a real quality red flag mold or mildew growth ². Below, we break down each cause, show you how to fix it, and explain what to demand from your supplier.

Why does my natural rattan cane webbing have a strong earthy or musty smell?

When we harvest and process rattan at our facility in Indonesia, the freshly cut cane carries a distinct plant scent Sulfur dioxide fumigation ³. Buyers who handle raw material for the first time often mistake this natural smell for a defect. It catches people off guard, but it rarely means trouble.

Natural rattan cane webbing smells earthy because it is made from organic plant fibers that retain residual sap, resin, and cellulose compounds after harvesting. This scent is normal in freshly processed cane and typically fades within two to four weeks when stored in a dry, ventilated space.

The Biology Behind the Smell

Le rotin est un palmier grimpant ⁴. Its stems are dense with natural oils, resins, and sugars. When we strip, boil, and dry the cane, most volatile compounds ⁵ evaporate. But some remain trapped in the porous fiber structure. These residual organics produce a mild, woody, or earthy scent.

The smell is stronger in certain species. Cane sourced from humid tropical forests in Kalimantan or Sulawesi tends to carry more resin than cane from drier regions. Thicker cane also holds more odor because the core retains moisture longer during drying.

When Earthy Becomes Musty

There is a clear line between "earthy" and "musty." Earthy smells are light and plant-like. Musty smells are heavy, damp, and stale. If your rattan webbing smells musty, moisture is the culprit. This can happen during transit when containers sit in port for weeks, or in warehouses with poor airflow.

Why Porous Fibers Trap Smells

Rattan fibers work like tiny sponges. Their cell structure is full of microscopic channels. These channels absorb airborne particles, humidity, and gases from the surrounding environment. Once absorbed, smells sit deep in the fiber and release slowly. This is why a roll stored in a smoky warehouse will carry that scent for weeks.

In our experience shipping to over 15 countries, the most common complaint comes from buyers who store rolls in basements or garages before use. The rattan absorbs ambient moisture and odors from those spaces within days. We always advise storing rolls in climate-controlled rooms, elevated off concrete floors.

The key takeaway is simple. A mild earthy smell is part of the material's identity. It is not a flaw. But if the smell is strong, wet, or pungent, you need to investigate further before using the webbing.

Is the odor in my rattan shipment a sign of poor quality or improper drying?

Our quality control team inspects every batch before it leaves the factory floor, and one of the checks they perform is a simple smell test. We learned years ago that certain odors reveal exactly what went wrong — and when — during production or storage.

Odor alone does not always indicate poor quality. Light plant or chemical smells in new rattan are normal and fade quickly. However, persistent musty or sour odors often signal improper drying, inadequate ventilation during storage, or mold growth — all of which can weaken the material and shorten its lifespan.

How Drying Affects Odor

Proper drying is the single most important step in rattan processing. At our Indonesian facility, we dry cane in open-air racks for several days, then move it to controlled drying rooms. If the la teneur en humidité ⁷ stays above 14–16%, the cane becomes a breeding ground for mold.

Underdried rattan smells different from properly dried rattan. The scent is heavier, damper, and more sour. When you bend underdried cane, it feels slightly soft or flexible in a rubbery way, rather than firm and springy.

Chemical Treatments and Off-Gassing

Many manufacturers apply chemical treatments ⁸ to rattan. These include:

• Sulfur dioxide fumigation — used to bleach and preserve cane, leaves a faint sulfur smell.
• Insecticide or pesticide dips — protect against wood borers, can smell chemical or medicinal.
• Varnish or lacquer coatings — seal the surface, produce a paint-like smell when new.
• Preservative oils — prevent cracking, may smell oily or slightly rancid.

These smells are strongest when rolls are tightly wrapped in plastic for shipping. The volatile compounds cannot escape, so they concentrate inside the packaging. Once you open the rolls and let them breathe, most chemical odors dissipate in three to seven days.

Red Flags vs. Normal Signs

The Mold Question

Mold is the biggest concern. It thrives in warm, humid, and poorly ventilated conditions. Rattan's organic composition provides an ideal food source for mold spores. Once mold colonizes the fibers, it produces metabolic byproducts that smell musty or sometimes like urine.

Here is what many buyers do not realize: mold can grow inside the fiber core without showing on the surface. This is because capillary action ⁹ draws moisture deep into the cane. By the time you see spots on the outside, the interior may already be compromised.

We have seen batches from other suppliers arrive with no visible mold but a strong musty odor. When our team cut cross-sections of the cane, they found dark, softened cores. This is core rot. It is irreversible. No amount of cleaning will fix it.

When to Accept and When to Reject

If you are a wholesaler or furniture factory receiving a large shipment, do a quick assessment. Open three to five rolls from different positions in the container. Smell them. Inspect the surfaces. Bend a few strands. If the odor is light and the material looks and feels healthy, you are fine. If the smell is intense and you see discoloration or softness, document it immediately and contact your supplier.

How can I safely remove odors from my rattan rolls without damaging the material?

Over the years, we have tested dozens of odor-removal methods at our Foshan facility and shared the results with buyers across the Netherlands, Australia, and the US. Some methods work beautifully. Others ruin the webbing. Here is what actually works.

To safely remove odors from rattan rolls, start by unwrapping and airing them in a dry, ventilated space with indirect sunlight for two to five days. For stubborn smells, wipe surfaces with a diluted white vinegar solution, sprinkle baking soda between layers, or place activated charcoal nearby to absorb residual odors without wetting the fibers.

Step 1: Ventilation First

The simplest and safest method is fresh air. Unroll the webbing or at least loosen the rolls. Place them in a well-ventilated room or covered outdoor area. Avoid direct sunlight, which can bleach and dry out the cane too quickly, causing cracks.

Most new-product odors — both plant-based and chemical — will disappear within two to five days of airing. If the smell persists after five days, move to the next level.

Step 2: Natural Absorbents

Natural odor absorbers are effective and safe for rattan. They work by trapping odor molecules without introducing moisture.

Step 3: Targeted Cleaning for Mold or Mildew

If you see mold spots or the musty smell persists after ventilation, you need to clean the webbing directly. Here is a safe process:

1. Mix a cleaning solution. Combine one tablespoon of mild dish soap and two tablespoons of white vinegar in one liter of warm water.
2. Wipe, do not soak. Use a soft cloth or sponge. Wring it out thoroughly. Wipe the affected areas gently. Never submerge rattan rolls in water.
3. Dry immediately. Pat dry with a clean towel. Then place the webbing in a ventilated area. Use a fan to speed up drying. The goal is to remove all moisture within a few hours.
4. Apply linseed oil or mineral oil. Once fully dry, a thin coat of oil conditions the fibers and helps prevent future moisture absorption.

Ce qu'il faut éviter

Certain common cleaning products will damage rattan. Stay away from:

• Bleach at full strength. It strips natural oils and weakens fibers. If you must use bleach, dilute it heavily — one teaspoon per liter of water, maximum.
• Steam cleaners. The concentrated moisture and heat push water deep into the core, promoting hidden mold.
• Pressure washers. They destroy the weave structure and force water into every crevice.
• Ammonia-based cleaners. They react with the natural tannins in rattan and can cause discoloration.

Preventing Odors Before They Start

Prevention always beats treatment. When we package rolls for export, we include sachets de gel de silice ¹⁰ inside the wrapping to absorb transit moisture. We also advise buyers to open shipments within 48 hours of arrival and let the rolls breathe before storing them long term.

For buyers who stock rattan in warehouses, keep humidity below 60%. Use dehumidifiers if needed. Store rolls on racks, not directly on concrete floors. And never stack wet or damp products next to dry rattan — moisture transfers quickly between rolls.

What should I look for in a wholesaler to ensure my rattan arrives fresh and odor-free?

When we started exporting rattan over a decade ago, we quickly learned that product quality means nothing if the material arrives smelling like a wet basement. The supply chain — from drying to packing to shipping — determines whether your rattan reaches you in perfect condition or with problems.

To ensure odor-free rattan, choose a wholesaler who controls their own drying process, uses moisture-resistant packaging with desiccants, provides documented moisture content readings below 14%, and ships through reliable logistics channels with minimal port delays. Ask for sample rolls before placing bulk orders.

Questions clés à poser à votre fournisseur

Before you commit to a large order, ask these specific questions:

1. What is the moisture content of your cane at the time of packing? The answer should be between 10% and 14%. Anything above 14% is a mold risk.
2. Do you control your own drying facility? Suppliers who outsource drying have less control over quality. We operate our own drying rooms in Indonesia specifically to avoid this problem.
3. What treatments do you apply? You have a right to know whether the cane has been fumigated, bleached, or coated. This helps you predict what smell to expect.
4. How do you package rolls for export? Look for suppliers who use breathable wrapping materials, include silica gel or desiccant packets, and avoid sealing rolls in airtight plastic for long periods.
5. What is your average shipping time? Longer transit means more time for moisture buildup inside containers. Suppliers with established shipping routes and reliable freight partners minimize this risk.

What Separates Good Suppliers from Great Ones

The Role of Packaging in Odor Prevention

Packaging is where many suppliers cut corners. Tight plastic wrap seals in moisture and volatile compounds from treatments. If the container heats up during transit — which happens regularly on routes through tropical waters — that trapped moisture condenses inside the packaging. This creates a mini greenhouse effect. Mold can start growing in as little as 72 hours under these conditions.

At Seafan Rattan, we switched to a hybrid packaging approach several years ago. We wrap rolls in a breathable inner layer, then add a moisture-barrier outer layer with ventilation channels. We also place desiccant packets at multiple points inside the packaging. The result is dramatically fewer odor complaints from our buyers.

Certifications and Documentation

Reputable suppliers provide documentation that goes beyond a basic invoice. Look for:

• Phytosanitary certificates — confirm the cane has been treated to international pest standards.
• Moisture test reports — show exact readings at the time of packing.
• Material safety data sheets (MSDS) — for any chemical treatments applied.
• Photos of storage and packing conditions — transparency builds trust.

Construire une relation à long terme

The best way to ensure consistent, odor-free rattan is to build a long-term relationship with one reliable supplier. When we work with repeat buyers — like our clients in the Netherlands and Australia — we learn their exact quality standards over time. We know which patterns they prefer, what moisture level their climate demands, and how they want rolls packaged. This kind of partnership eliminates surprises.

If you are sourcing rattan for the first time, start with a small trial order. Inspect it thoroughly. Test the smell, the flexibility, and the visual quality. If everything checks out, scale up gradually. This approach protects your investment and gives you leverage to negotiate better terms as volumes grow.

Conclusion

Odors in natural rattan cane webbing usually come from plant compounds, chemical treatments, moisture, or mold. Most new-product smells fade with ventilation. Persistent odors signal deeper issues. Choose a supplier who controls drying, packaging, and documentation to protect your investment.
