Most recycled yarn suppliers are based in Asia or Southeast Asia, where production costs are lower and supply chains are more established. ESB Trading Company is headquartered in the United States, which gives it access to North American markets and potentially better compliance with local environmental and labor standards. However, no phone, work email, or business documents have been verified — this raises concerns about legitimacy and responsiveness. Being founded in 2000 shows the company has been in business for over two decades, which suggests stability and experience. Without verification, buyers should treat the company as a potential risk and request additional proof before placing large orders or sharing sensitive requirements.
