                                                            Warning! Caution for professionals:  Numerous scammers are active online, offering supposedly similar products at prices hundreds of times higher than the real value, and trading products by the gram (!). This is clear fraud, often supported by certain European laboratories like IGAS or ICE. It's important to understand that these organizations are just laboratories, with no right to evaluate goods that are not separately listed on the London Metal Exchange (LME). Unfortunately, many traders blindly trust these dubious assessments, cluttering trading platforms with unreliable information. We hope that this site is frequented by real professionals, not intermediaries.  We appeal to you: be vigilant, beware of international fraud. Work directly with manufacturers, verify information, and don't trust excessively inflated prices and questionable certificates. Your awareness is the best protection against deception in the specialized materials trade.

                                                                警告！专业人士请注意：网上活跃着众多骗子，他们提供据称类似的产品，价格却是实际价值的数百倍，甚至按克（！）出售产品。这是明显的欺诈行为，常常得到一些欧洲实验室（如IGAS或ICE）的支持。重要的是要明白，这些组织只是实验室，无权评估未在伦敦金属交易所（LME）单独列出的商品。不幸的是，许多交易商盲目信任这些可疑的评估，用不可靠的信息污染了交易平台。我们希望本网站的用户是真正的专业人士，而不是中间商。我们呼吁您：保持警惕，谨防国际欺诈。直接与制造商合作，核实信息，不要相信过高的价格和可疑的证书。您的认知是防止在专业材料交易中受骗的最佳保护
