These organic traits come from the rattan palm&#8217;s natural fiber structure and are not defects. They reflect the authentic character of genuine rattan and are expected across all but the highest premium grades.<\/strong><\/p>\n<p>But that does not mean every dark mark is harmless <a href=\"https:\/\/www.fao.org\/3\/t0119e\/t0119e03.htm\" target=\"_blank\" rel=\"noopener noreferrer\">rattan palm&#8217;s natural fiber structure<\/a> <sup id=\"ref-2\"><a href=\"#footnote-2\" class=\"footnote-ref\">2<\/a><\/sup>. Some spots signal moisture damage or mold. Knowing the difference protects your investment. Let&#8217;s walk through exactly what to look for, what each grade allows, and how to manage expectations across your supply chain.<\/p>\n<h2>Why does my rattan cane webbing have black spots and uneven colors?<\/h2>\n<p>When we first started processing raw rattan at our Indonesian facility, even our own quality inspectors questioned the dark spots on freshly peeled cane <a href=\"https:\/\/www.fao.org\/3\/t0119e\/t0119e04.htm\" target=\"_blank\" rel=\"noopener noreferrer\">boiling and drying stages<\/a> <sup id=\"ref-3\"><a href=\"#footnote-3\" class=\"footnote-ref\">3<\/a><\/sup>. The truth surprised us. Most of those marks were already inside the plant before it was ever harvested.<\/p>\n<p><strong>Black spots in rattan cane webbing result from natural pigmentation in the rattan palm&#39;s outer skin, environmental exposure during growth, and minor caramelization during the boiling and drying stages of production. Uneven colors reflect natural fiber density differences across each vine.<\/strong><\/p>\n<p><img decoding=\"async\" style=\"max-width:100%; height:auto;\" src=\"https:\/\/rattanwholesaler.com\/wp-content\/uploads\/2026\/03\/v2-article-1772916828966-2.jpg\" alt=\"Rattan cane webbing with black spots from natural pigmentation and environmental exposure (ID#2)\" title=\"Causes of rattan spots\"><\/p>\n<h3>Where Do Black Spots Come From?<\/h3>\n<p><a href=\"https:\/\/en.wikipedia.org\/wiki\/Rattan\" target=\"_blank\" rel=\"noopener noreferrer\">Rattan palms grow<\/a> <sup id=\"ref-4\"><a href=\"#footnote-4\" class=\"footnote-ref\">4<\/a><\/sup> in dense Indonesian tropical forests. During their 7\u201310 year growth cycle, the vines encounter insects, mineral deposits in soil, and varying sunlight exposure. All of these leave traces in the outer peel. When we harvest and boil the cane, these traces become visible as small dark spots <a href=\"https:\/\/www.conservation-wiki.com\/wiki\/Rattan_and_Cane\" target=\"_blank\" rel=\"noopener noreferrer\">UV exposure<\/a> <sup id=\"ref-5\"><a href=\"#footnote-5\" class=\"footnote-ref\">5<\/a><\/sup>.<\/p>\n<p>The boiling process itself also plays a role. Boiling softens the rattan for peeling and kills potential pests. But the heat causes natural sugars in the cane to caramelize slightly. This creates subtle brown or black marks, especially where the fiber is denser.<\/p>\n<h3>Why Colors Vary From Roll to Roll<\/h3>\n<p>No two rattan vines grow in identical conditions. A vine growing in partial shade develops lighter, greenish-toned cane. One in full sun produces deeper golden tones. When we peel and dry these vines, the color differences become permanent.<\/p>\n<p>Even within a single roll of woven webbing, you can see shifts from pale straw yellow to warm sandy tan. This is because weavers pull strips from multiple processed vines to complete one sheet.<\/p>\n<h3>Processing Steps That Affect Appearance<\/h3>\n<table>\n<thead>\n<tr>\n<th>Processing Stage<\/th>\n<th>Effect on Color<\/th>\n<th>Effect on Spots<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Boiling<\/td>\n<td>Darkens overall tone slightly<\/td>\n<td>Can intensify existing natural spots<\/td>\n<\/tr>\n<tr>\n<td>Sun Drying<\/td>\n<td>Creates golden-yellow hues<\/td>\n<td>Minimal effect<\/td>\n<\/tr>\n<tr>\n<td>Machine Drying<\/td>\n<td>More uniform pale color<\/td>\n<td>Minimal effect<\/td>\n<\/tr>\n<tr>\n<td>Peeling<\/td>\n<td>Exposes inner color variations<\/td>\n<td>Reveals hidden pigmentation<\/td>\n<\/tr>\n<tr>\n<td>Singeing<\/td>\n<td>Smooths surface, slight browning<\/td>\n<td>Can add tiny scorch marks<\/td>\n<\/tr>\n<tr>\n<td>Bleaching<\/td>\n<td>Lightens and evens tone<\/td>\n<td>Reduces visibility of spots<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Our production team in Foshan has tracked these patterns across thousands of rolls. The takeaway is simple: natural color variation is built into the material at every stage. Bleaching can reduce it, but it also changes the authentic look many designers specifically want.<\/p>\n<h3>Mold Spots vs. Natural Spots<\/h3>\n<p>Here is the critical distinction. Natural pigmentation spots are flat, embedded in the fiber, and feel smooth to the touch. Mold spots sit on the surface, feel slightly raised or fuzzy, and often have a musty smell. If you rub a mold spot with a damp cloth, it may smear. A natural spot will not.<\/p>\n<p>Mold develops when rattan is stored in humid conditions above 70% <a href=\"https:\/\/www.conservation-wiki.com\/wiki\/Rattan_and_Cane\" target=\"_blank\" rel=\"noopener noreferrer\">relative humidity<\/a> <sup id=\"ref-6\"><a href=\"#footnote-6\" class=\"footnote-ref\">6<\/a><\/sup> without proper ventilation. This is a storage and shipping issue, not a manufacturing defect. We always advise buyers to inspect shipments immediately upon arrival and store rolls in dry, ventilated spaces.<\/p>\n<div class=\"claim-pair\">\n<div class=\"claim claim-true\">\n<div class=\"claim-title\"><span class=\"claim-icon\">\u2714<\/span> Natural black spots in rattan are caused by organic pigmentation and heat during processing, not by decay or contamination. <span class=\"claim-label\">True<\/span><\/div>\n<div class=\"claim-explanation\">These spots originate from mineral deposits, insect contact during growth, and caramelization of natural sugars during boiling. They are structurally harmless and embedded within the fiber.<\/div>\n<\/div>\n<div class=\"claim claim-false\">\n<div class=\"claim-title\"><span class=\"claim-icon\">\u2718<\/span> All black spots on rattan webbing indicate mold or water damage. <span class=\"claim-label\">False<\/span><\/div>\n<div class=\"claim-explanation\">Most black spots are natural pigmentation. Mold spots are distinguishable by their raised, fuzzy texture and musty odor. Confusing the two leads to unnecessary product rejections.<\/div>\n<\/div>\n<\/div>\n<h2>How can I tell if these color variations mean my rattan is low quality?<\/h2>\n<p>During trade shows and factory visits, purchasing managers often hold two rattan samples side by side and assume the whiter, smoother one is always &quot;better.&quot; In our experience exporting to over a dozen countries, that assumption costs buyers money \u2014 because the answer depends entirely on the intended use.<\/p>\n<p><strong>Color variations alone do not indicate low quality. Rattan quality is determined by a grading system (A through D) that evaluates elasticity, surface smoothness, crack frequency, and fiber consistency. Minor color shifts exist even in A-grade material, while severe roughness and poor flexibility signal genuinely lower grades.<\/strong><\/p>\n<p><img decoding=\"async\" style=\"max-width:100%; height:auto;\" src=\"https:\/\/rattanwholesaler.com\/wp-content\/uploads\/2026\/03\/v2-article-1772916833773-3.jpg\" alt=\"High quality rattan grading system evaluating elasticity and surface smoothness despite color shifts (ID#3)\" title=\"Rattan quality grading system\"><\/p>\n<h3>Understanding the Rattan Grading System<\/h3>\n<p>The international rattan trade uses a four-tier grading system. <a href=\"https:\/\/wikieducator.org\/Bamboo_and_Rattan\/Rattan\/Course-2_Unit-7\" target=\"_blank\" rel=\"noopener noreferrer\">rattan grading system<\/a> <sup id=\"ref-7\"><a href=\"#footnote-7\" class=\"footnote-ref\">7<\/a><\/sup> Each grade has specific visual and structural characteristics. Here is how they break down:<\/p>\n<table>\n<thead>\n<tr>\n<th>Grade<\/th>\n<th>Surface Texture<\/th>\n<th>Color Consistency<\/th>\n<th>Elasticity<\/th>\n<th>Typical Defects<\/th>\n<th>Best Use<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>A-Grade<\/td>\n<td>Very smooth, fine<\/td>\n<td>Most uniform, whiter tone<\/td>\n<td>Excellent, highly flexible<\/td>\n<td>Virtually defect-free<\/td>\n<td>High-end furniture, restoration, premium DIY<\/td>\n<\/tr>\n<tr>\n<td>B-Grade<\/td>\n<td>Slightly coarser<\/td>\n<td>Minor color shifts<\/td>\n<td>Good flexibility<\/td>\n<td>Small cracks, occasional spots<\/td>\n<td>Mid-range furniture, visible applications<\/td>\n<\/tr>\n<tr>\n<td>C-Grade<\/td>\n<td>Noticeably rough<\/td>\n<td>Pronounced variation<\/td>\n<td>Average<\/td>\n<td>Frequent spots, visible cracks<\/td>\n<td>Budget furniture, non-visible panels<\/td>\n<\/tr>\n<tr>\n<td>D-Grade<\/td>\n<td>Roughest finish<\/td>\n<td>Most uneven<\/td>\n<td>Poor, brittle<\/td>\n<td>Many defects, rough edges<\/td>\n<td>Cheap products, practice material<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>What to Actually Test<\/h3>\n<p>Color is just one data point. When we send trade samples to potential buyers, we always recommend three hands-on tests:<\/p>\n<p><strong>Bend test.<\/strong> Take a single strand and bend it 90 degrees. A-grade rattan springs back without cracking. D-grade snaps or splinters.<\/p>\n<p><strong>Surface feel.<\/strong> Run your finger along the weave. A-grade feels almost silky after singeing. Lower grades catch on rough spots and raised fibers.<\/p>\n<p><strong>Smell test.<\/strong> Fresh, clean rattan smells faintly like dried grass. A sour or musty smell indicates moisture problems during storage, regardless of grade.<\/p>\n<h3>When Color Variation Is Actually a Red Flag<\/h3>\n<p>There are situations where color signals a real problem. If an entire roll shows large, irregular dark patches \u2014 not small spots but broad discoloration \u2014 it may mean the rattan was improperly dried. Uneven drying creates weak zones that crack under stress.<\/p>\n<p>Also watch for rolls that are extremely white and uniform. Aggressive bleaching achieves visual consistency but strips natural oils from the fiber. This makes the rattan brittle over time. We have seen bleached rattan crack within months on furniture that sees daily use.<\/p>\n<p>The sweet spot is rattan that has gentle color variation, a warm natural tone, and smooth flexibility. This signals proper processing without over-treatment.<\/p>\n<h3>Grade Selection for Common Applications<\/h3>\n<p>Most of our wholesale buyers do not need A-grade for every project. A purchasing manager ordering rattan for cabinet door inserts, for example, often finds B-grade perfectly suitable because the webbing sits behind glass or in recessed panels. Saving the A-grade budget for visible headboard panels or chair seats makes better financial sense.<\/p>\n<div class=\"claim-pair\">\n<div class=\"claim claim-true\">\n<div class=\"claim-title\"><span class=\"claim-icon\">\u2714<\/span> Rattan quality is best assessed through elasticity, surface smoothness, and structural integrity \u2014 not color alone. <span class=\"claim-label\">True<\/span><\/div>\n<div class=\"claim-explanation\">The grading system prioritizes physical performance. A roll with slight color variation but excellent flexibility and a smooth surface is superior to a uniformly colored but brittle roll.<\/div>\n<\/div>\n<div class=\"claim claim-false\">\n<div class=\"claim-title\"><span class=\"claim-icon\">\u2718<\/span> The whitest, most uniform rattan webbing is always the highest quality. <span class=\"claim-label\">False<\/span><\/div>\n<div class=\"claim-explanation\">Excessive whiteness often results from aggressive bleaching, which degrades fiber strength and natural oils. Properly processed A-grade rattan has a warm, natural tone with minimal \u2014 but not zero \u2014 color variation.<\/div>\n<\/div>\n<\/div>\n<h2>What steps can I take to minimize color inconsistencies in my bulk rattan shipments?<\/h2>\n<p>When we prepare orders for furniture material wholesalers in the Netherlands or Australia, color consistency is always near the top of their concern list. Over years of refining our processes, our production team has developed a practical approach that balances natural material reality with commercial expectations.<\/p>\n<p><strong>To minimize color inconsistencies, request single-batch sourcing, specify your target grade clearly, ask for pre-shipment photo approval, and store received goods in climate-controlled environments. Communicate acceptable color range using physical samples rather than digital images to align expectations with your supplier.<\/strong><\/p>\n<p><img decoding=\"async\" style=\"max-width:100%; height:auto;\" src=\"https:\/\/rattanwholesaler.com\/wp-content\/uploads\/2026\/03\/v2-article-1772916837374-4.jpg\" alt=\"Minimizing color inconsistencies in bulk rattan shipments through single-batch sourcing and photo approval (ID#4)\" title=\"Managing rattan color consistency\"><\/p>\n<h3>Work With Your Supplier Before Production<\/h3>\n<p>The most effective step happens before a single roll is woven. Send your supplier a physical sample of the color range you find acceptable. Digital photos shift color depending on screens and lighting. A physical reference removes ambiguity.<\/p>\n<p>At our Foshan headquarters, we keep reference samples from every major buyer. When their next order comes in, our Indonesian facility matches against these saved samples. This simple system has reduced color complaints by a significant margin across our export orders.<\/p>\n<h3>Specify Single-Batch Sourcing<\/h3>\n<p>Rattan harvested from the same forest area and processed in the same batch window will have the most consistent color. When suppliers mix batches from different harvest periods or regions, color shifts increase.<\/p>\n<p>Ask your supplier: &quot;Can this order be fulfilled from a single processing batch?&quot; Not every supplier can guarantee this for very large orders, but the request signals your quality expectations clearly.<\/p>\n<h3>Pre-Shipment Inspection Checklist<\/h3>\n<p>Before your shipment leaves the factory, a structured inspection catches problems early. Here is what we recommend buyers verify:<\/p>\n<table>\n<thead>\n<tr>\n<th>Inspection Point<\/th>\n<th>What to Check<\/th>\n<th>Accept\/Reject Criteria<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Color range<\/td>\n<td>Compare against approved sample<\/td>\n<td>Reject if &gt;20% of rolls fall outside approved range<\/td>\n<\/tr>\n<tr>\n<td>Black spots<\/td>\n<td>Flat, embedded, smooth to touch<\/td>\n<td>Accept natural spots; reject raised\/fuzzy mold spots<\/td>\n<\/tr>\n<tr>\n<td>Surface cracks<\/td>\n<td>Bend-test random strips<\/td>\n<td>Accept hairline surface marks; reject through-cracks<\/td>\n<\/tr>\n<tr>\n<td>Smell<\/td>\n<td>Sniff test for mustiness<\/td>\n<td>Reject any roll with sour or moldy odor<\/td>\n<\/tr>\n<tr>\n<td>Roll edges<\/td>\n<td>Check for fraying or breakage<\/td>\n<td>Minor fraying acceptable; torn edges rejected<\/td>\n<\/tr>\n<tr>\n<td>Packaging<\/td>\n<td>Moisture barrier, ventilation holes<\/td>\n<td>Reject if packaging is damp or sealed without ventilation<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Storage and Handling After Delivery<\/h3>\n<p>Even perfectly graded rattan can develop color problems after delivery if storage conditions are wrong. Keep rolls in a space with 40\u201360% relative humidity and temperatures between 15\u201330\u00b0C. Avoid direct sunlight, which causes oxidation and darkening over days.<\/p>\n<p>Stack rolls horizontally on pallets, not directly on concrete floors. Concrete transfers moisture upward. Place a moisture barrier sheet between the pallet and the first layer of rolls.<\/p>\n<h3>The Role of Bleaching and Finishing<\/h3>\n<p>Some buyers request bleached rattan for maximum color uniformity. Our facility offers this option, but we always discuss the trade-offs. Bleaching lightens color effectively but slightly reduces fiber elasticity. For decorative panels that won&#39;t bear weight, bleached rattan works well. For chair seats or structural weaving, we recommend natural-finished A-grade instead.<\/p>\n<p>A middle path is light bleaching \u2014 just enough to even out major tone differences without stripping the fiber completely. This approach satisfies buyers who want a cleaner look while preserving the material&#39;s natural strength.<\/p>\n<div class=\"claim-pair\">\n<div class=\"claim claim-true\">\n<div class=\"claim-title\"><span class=\"claim-icon\">\u2714<\/span> Physical reference samples are more reliable than digital photos for communicating acceptable color ranges to rattan suppliers. <span class=\"claim-label\">True<\/span><\/div>\n<div class=\"claim-explanation\">Screen calibration, lighting conditions, and camera settings all distort color in digital images. A physical sample provides an objective, unchanging reference that both buyer and supplier can match against.<\/div>\n<\/div>\n<div class=\"claim claim-false\">\n<div class=\"claim-title\"><span class=\"claim-icon\">\u2718<\/span> Bleaching rattan cane webbing is a cost-free way to achieve perfect color consistency with no drawbacks. <span class=\"claim-label\">False<\/span><\/div>\n<div class=\"claim-explanation\">Bleaching strips natural oils and reduces fiber elasticity. Over-bleached rattan becomes brittle and prone to cracking, especially in applications that involve bending or load-bearing.<\/div>\n<\/div>\n<\/div>\n<h2>Should I be worried about the durability of rattan webbing with natural dark spots?<\/h2>\n<p>One of the most common questions we hear from furniture factory procurement teams is whether those dark spots weaken the material. It is a fair concern \u2014 if something looks different, maybe it performs differently. We ran our own internal tests at our processing facility to find out.<\/p>\n<p><strong>Natural dark spots do not compromise rattan webbing durability. These pigmentation marks are cosmetic, embedded within the fiber structure, and have no measurable effect on tensile strength or flexibility. Rattan&#39;s durability depends on grade, proper processing, and post-installation care \u2014 not on the presence of natural color markings.<\/strong><\/p>\n<p><img decoding=\"async\" style=\"max-width:100%; height:auto;\" src=\"https:\/\/rattanwholesaler.com\/wp-content\/uploads\/2026\/03\/v2-article-1772916841427-5.jpg\" alt=\"Durable rattan webbing with cosmetic dark spots that do not affect tensile strength (ID#5)\" title=\"Rattan durability and spots\"><\/p>\n<h3>Structural Integrity Is Independent of Spot Color<\/h3>\n<p>The dark spots in rattan come from localized concentrations of tannins and minerals absorbed during growth. These substances are distributed throughout the fiber. A spot is simply a place where the concentration is slightly higher. It does not create a weak point any more than a freckle weakens human skin.<\/p>\n<p>When we pull-test rattan strips \u2014 stretching them until they break \u2014 strips with natural spots break at the same point as spot-free strips of the same grade. The failure point is always determined by fiber density and moisture content, never by surface pigmentation.<\/p>\n<h3>What Actually Affects Rattan Durability<\/h3>\n<p>Understanding the real durability factors helps buyers focus their quality control on what matters:<\/p>\n<p><strong>Moisture exposure.<\/strong> Sustained humidity above 70% weakens rattan over time. The fibers absorb water, swell, and eventually break down. This is why rattan is best suited for indoor use unless treated with moisture-resistant coatings.<\/p>\n<p><strong>UV exposure.<\/strong> Direct sunlight causes oxidation. The rattan darkens, becomes brittle, and loses flexibility. Indoor rattan near windows should be protected with UV-filtering glass or curtains.<\/p>\n<p><strong>Mechanical stress.<\/strong> Rattan has excellent <a href=\"https:\/\/en.wikipedia.org\/wiki\/Rattan\" target=\"_blank\" rel=\"noopener noreferrer\">tensile strength<\/a> <sup id=\"ref-8\"><a href=\"#footnote-8\" class=\"footnote-ref\">8<\/a><\/sup> for its weight. But repeated sharp bending in the same spot \u2014 like a chair seat flexing at the front edge \u2014 will eventually cause fatigue cracking. Proper frame support distributes this stress.<\/p>\n<h3>The Beauty of Natural Patina<\/h3>\n<p>Here is something our long-term buyers have learned to appreciate. Over months and years, rattan develops a warm patina. The initial pale straw tone deepens to rich honey gold. Natural spots blend into this deeper tone and become nearly invisible.<\/p>\n<p>This patina is not degradation. It is a surface-level color change caused by gentle oxidation and oil absorption from normal use. Furniture makers in the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Wabi-sabi\" target=\"_blank\" rel=\"noopener noreferrer\">Wabi-Sabi and biophilic design movements<\/a> <sup id=\"ref-9\"><a href=\"#footnote-9\" class=\"footnote-ref\">9<\/a><\/sup> actively seek this aging character. It signals authenticity in a way that synthetic rattan simply cannot replicate.<\/p>\n<h3>Natural Rattan vs. Synthetic: A Durability Perspective<\/h3>\n<p>Some buyers consider switching to synthetic rattan to avoid color variations entirely. That is a valid choice for outdoor applications. But for indoor furniture, natural rattan offers distinct advantages.<\/p>\n<p>Natural rattan breathes. It allows air circulation through woven panels, reducing trapped moisture behind cabinet doors or headboards. Synthetic rattan \u2014 typically made from polyethylene or PVC \u2014 does not breathe and can trap humidity against wood frames, potentially causing wood rot over time.<\/p>\n<p>Natural rattan also ages gracefully. Synthetic rattan maintains its original color for years, then suddenly fades or becomes chalky when UV degradation reaches a tipping point. There is no gradual, attractive aging process.<\/p>\n<h3>Maintenance Tips to Maximize Lifespan<\/h3>\n<p>Caring for rattan is straightforward. Dust regularly with a soft brush or vacuum with a brush attachment. For deeper cleaning, wipe with a cloth dampened in mild soapy water, then dry immediately. Never soak rattan. Avoid chemical cleaners, which strip natural oils and accelerate brittleness.<\/p>\n<p>Once or twice a year, apply a thin coat of <a href=\"https:\/\/www.conservation-wiki.com\/wiki\/Rattan_and_Cane\" target=\"_blank\" rel=\"noopener noreferrer\">linseed oil<\/a> <sup id=\"ref-10\"><a href=\"#footnote-10\" class=\"footnote-ref\">10<\/a><\/sup> or a dedicated rattan conditioner. This replenishes natural oils, maintains flexibility, and enhances the developing patina. Our buyers in drier climates like Saudi Arabia and Australia find this step especially important.<\/p>\n<div class=\"claim-pair\">\n<div class=\"claim claim-true\">\n<div class=\"claim-title\"><span class=\"claim-icon\">\u2714<\/span> Natural dark spots in rattan are cosmetic pigmentation and do not reduce the material&#8217;s tensile strength or structural durability. <span class=\"claim-label\">True<\/span><\/div>\n<div class=\"claim-explanation\">Pull-testing confirms that spotted and spot-free strips of the same grade break at equivalent stress points. Spots are tannin concentrations, not structural flaws.<\/div>\n<\/div>\n<div class=\"claim claim-false\">\n<div class=\"claim-title\"><span class=\"claim-icon\">\u2718<\/span> Rattan webbing with visible dark spots will deteriorate faster than spot-free rattan. <span class=\"claim-label\">False<\/span><\/div>\n<div class=\"claim-explanation\">Durability is determined by grade, moisture management, and UV protection \u2014 not by surface pigmentation. Dark spots blend into the natural patina over time and have no bearing on lifespan.<\/div>\n<\/div>\n<\/div>\n<h2>Conclusion<\/h2>\n<p>Natural rattan&#39;s black spots and color variations are authentic traits, not flaws. Understanding grading, proper inspection, and correct storage turns these organic characteristics from a source of worry into a mark of genuine quality that synthetic alternatives simply cannot match.<\/p>\n<h2>Footnotes<\/h2>\n<p><span id=\"footnote-1\"><br \/>\n1.
