In the current market, the name of " mahogany furniture ", the origin of the specification should be China's light industry standard QB / T2385-98. The standard name is "Furniture-Dark Color Hardwood Furniture" (hereinafter referred to as "Standard"). In the preface of "Standard", there are the following contents: "Dark and precious hardwood furniture (redwood furniture is only a part of it), as a traditional solid wood craft furniture in China, has a long history and exquisite workmanship. It is a treasure in China. Considering the historical evolution , Taking into account the national customs and innovation, this standard stipulates that the furniture must be named and marked according to the name of the product mainly using wood species. " From this we know that "mahogany furniture" is just a kind of "dark and precious hardwood furniture". It is a type of furniture named and marked mainly by the name of certain wood species. So, what kind of wood species can be named as "mahogany furniture"? The scope of "mahogany" in Appendix A of the Standard includes: red sandalwood, yellow rosewood, rosewood, rosewood, ebony, wenge , Lattice wood, lattice wood, iron wood and wood pod wood, etc. Only these tree species are furniture that mainly uses wood, can they be called "mahogany furniture".

Dark hardwood furniture has a long history in our country, especially the dark hardwood furniture in the Ming and Qing dynasties, once wrote a glorious page in the history of furniture in the world. As the successor of Chinese civilization, our mission is not to imitate and repeat history, but to create a new and more glorious history. Today's furniture industry is still difficult to surpass the ancestors' achievements in the short term due to various reasons, but at least we should not do stupid things that cannot be explained to future generations in the selection of furniture materials.

Questioning the standard of mahogany furniture
Â
The "Standard" QB / T2385-98 for mahogany furniture was published on May 14, 1998 and was implemented on March 1, 1999. It has not been revised so far, and no new standard replacement has been seen. Obvious lag. What is more important is that the author believes that the main content of the Standard is questionable. First of all, "Standard" stipulates that "the furniture must be named and marked according to the name of the product mainly using wood species". It also specifies the specific types of mahogany furniture wood species, such as rosewood, huanghua pear, rosewood, etc .; then there are definitely some "beautiful heartwood patterns, hard, hard, heavy, corrosion-resistant and anti-corrosion" in addition to the "standard" "Moth, stable wood properties" are tree species that are very close to the content of the "Standard". Are these tree species regarded as mahogany? In addition, the wood species of the "mahogany furniture" specified in the "Standard" are rare and wild in the tropical and subtropical regions. Tree species, which grow slowly, have a long timber cycle, and have few survivors. The red sandalwood, Huanghua pear and other tree species specified in the "Standard" have been included in the scope of the "National List of Key Protected Wild Plants".
Â
On the mahogany furniture market
Â
According to statistics reported by the Consumers Association of China in the past year or two, the pass rate of the mahogany furniture market is only 40%, while consumer complaints about mahogany furniture are increasing year by year. As a consumer of mahogany furniture in real life, very few people have the expertise to identify mahogany materials, and it is difficult to understand the authenticity of the furniture materials purchased. In the event of a consumer dispute, our country does not have a statutory appraisal agency authorized by the state. Therefore, in the process of consumer rights protection, furniture material test reports issued by some scientific research institutions are often difficult to obtain legal approval.
Â
This undoubtedly makes the consumers of the mahogany furniture products in the disadvantaged group even worse, which increases the difficulty of defending rights. The reason why unscrupulous manufacturers make great fuss about the use of furniture materials is because the materials of mahogany furniture determine the price of furniture to a large extent. In addition to the confusion of the mahogany furniture material types, the moisture content of mahogany furniture products is another common problem that triggers consumer disputes. Manufacturers have at least two outstanding difficulties in controlling the moisture content of mahogany timber: First, among the mahogany tree species listed in the Standard, the drying process of many tree species is extremely complicated. For example, red sandalwood is due to its special pipe hole structure. So far, only a few manufacturers can control its drying process.
Â
In addition, China has a vast territory, and the dry and humidity of the air varies from place to place. Therefore, the country has made different regulations on the moisture content of furniture materials in various regions. If the moisture content of mahogany furniture is not properly handled in the drying process, or its products do not meet the moisture content requirements of the consumption area, it will cause the furniture to crack or deform during use. In addition, consumers also need to distinguish the manufacturing process of mahogany furniture, because in the manufacturing process of mahogany furniture, whether it is by hand or by machine, not only the technical effects of the finished furniture, but also the production costs are very different. All of these are numerous, causing unavoidable chaos in the mahogany furniture market. (Editor: Peter)
