I am reaching out to request a quotation for some taps that we need for our upcoming projects. We are interested in sourcing a total of 30 pieces, specifically in different sizes suitable for carbon steel applications. The sizes we are looking for include small, medium, and large options, and we would appreciate your best prices and lead times for these items. Could you also provide information regarding the quality standards and certifications for the taps? It's crucial for us to ensure that they meet our specifications. Additionally, if you have any recommendations for similar products or alternatives, please feel free to include those in your offer. Thank you for your assistance, and I look forward to your prompt response!
