长三角地区进出口14万亿元，同比增长6%；粤港澳大湾区内地9市进出口7.52万亿元，同比增长4%；京 津冀区域进出口3.91万亿元，其中出口再创新高，连续7个月保持增长……今年前10个月，中国区域外 贸呈现向新向优的升级趋势，展现出强劲韧性。 外贸主体作用日益凸显。前10个月，长三角地区民营企业进出口7.83万亿元，同比增长9.7%，占长三角 地区进出口总值的55.9%，民营企业作为外贸主力军的作用持续显现。 国光电器股份有限公司是广州市一家专注于音响及电声元器件设计的民营企业，其生产的蓝牙音响等产 品远销海外。"我们非常重视产品的原创设计，公司在第138届广交会上推出的明星产品便携式蓝牙音响 吸引了巴西等多个国家和地区采购商的青睐，目前已收获意向出口订单超2700万元。"该公司销售经理 谢武斌介绍。 业内人士认为，未来随着大湾区建设的深入推进和各项政策的落地实施，大湾区的进出口规模将继续保 持增长态势，电子信息产业也将迎来更加广阔的发展前景。同时，基础设施建设的不断完善，也将为大 湾区的内外联通和协同发展提供更加有力的支撑。 贸易多元化格局持续深化。前10个月，京津冀地区与240多个国家和地区保持稳定贸易往 ...

Group 1: Core Concept - The DOE (Department of Energy) certification aims to promote energy efficiency and reduce energy consumption in electronic and electrical products, thereby contributing to lower energy demand and mitigating greenhouse gas emissions [1]. Group 2: Products Requiring DOE Certification - Products that require DOE certification include small battery charging systems (e.g., Bluetooth headphones, smartphones), power supplies (e.g., chargers), televisions, audio/video devices (e.g., DVD players), information devices (e.g., set-top boxes), transformers, household appliances (e.g., refrigerators, air conditioners), motors, and bathroom products (e.g., faucets, toilets) [4][5][6][7][8][9][10][12]. Group 3: Water Efficiency Requirements - The DOE mandates water efficiency standards for bathroom products, with specific flow rate limits: - Bathroom/kitchen faucets: maximum flow rate of 2.2 gallons per minute (approximately 8.3 liters per minute) at a pressure of 60 psi (414 kPa) [13]. - Showerheads: maximum flow rate of 2.5 gallons per minute (approximately 9.5 liters per minute) at a pressure of 80 psi (552 kPa) [13]. - Urinals: maximum water usage of 1.6 gallons (approximately 6.0 liters) per flush for trough urinals [14]. Group 4: DOE Certification Process - The certification process involves several steps: 1. Confirm if the product falls under DOE certification requirements. 2. Prepare necessary documentation and samples, including specifications and circuit diagrams. 3. Select a compliance organization and apply for certification services. 4. Conduct sample testing for energy efficiency. 5. Obtain a detailed energy efficiency test report from the laboratory. 6. Register with the DOE by submitting the test report and required information online. 7. Update the Amazon backend with certification documents and energy efficiency labels [16].
