When it comes to factory strength, this manufacturer is an industry leader that excels in certifications, production capacity, and technical prowess. It holds a suite of international authoritative certifications, including SGS, FDA, ISO 9001, and HACCP—testaments to its adherence to global quality standards. Its facilities feature clean workshops and end-to-end production lines designed for food safety, covering every critical step: raw material extraction, precise powder blending, portioning, and final packaging. With an annual production capacity supporting a 100-million-yuan output value, it effortlessly handles both small-batch orders (starting from 500 units) and large-scale production runs (10,000+ units). A key advantage is its in-house plant extraction line, which allows it to control the purity and activity of core ingredients like L-carnitine and collagen from the source—ensuring the efficacy and reliability of every batch.
The L-carnitine black coffee itself is engineered to meet the core needs of weight-conscious consumers, boasting three competitive edges. First, safe and proven efficacy: Infused with dual active ingredients—caffeine and L-carnitine—it boosts energy metabolism, burns excess fat, and blocks the absorption of new fat. Its formula is "0 fat, no artificial sucrose, no non-dairy creamer," delivering a "burden-free" drinking experience that avoids the side effects of traditional slimming products, making it suitable even for athletes. Second, strong scenario adaptability: Packaged in 8g individual sachets, it’s lightweight and portable—perfect for on-the-go consumption. When brewed, it retains the rich, original aroma of coffee, balancing convenience with great taste. Third, flexible customization: Brands can tailor every aspect to their needs, from core ingredients (e.g., adding collagen for added skincare benefits) and flavors (chocolate, original, etc.) to packaging 规格 (300g bottles, sachet packs, etc.)—enabling unique market positioning.
In terms of service support, the manufacturer offers a one-stop OEM/ODM solution that minimizes collaboration barriers for clients. Early on, it provides free samples, letting brands test quality firsthand. Mid-project, it covers full-process support: formula R&D, packaging design (including LOGO customization and label template refinement), and real-time production tracking. It even offers insights to optimize functional messaging—such as highlighting "basal metabolism boost"—to resonate with consumers. Post-production, it partners with global logistics giants like TNT, FedEx, and EMS, paired with flexible payment options (T/T, PayPal, L/C) to streamline cross-border delivery and settlement. Plus, a 24/7 online customer service team ensures prompt order responses, and the controllable timeline from sample approval to bulk delivery helps brands get products to market faster.
