Questions buyers ask
How do I choose a tablet manufacturer in the USA?
Start with the USA list, check the exact facility and its certificate scope, and confirm supplement tablet manufacturing. Ask for the minimum order, first-run and reorder lead times, testing plan and an itemized quote. Website capabilities are company claims unless a separate registry basis is shown; confirm the proposed work directly.
What should I ask a tablet manufacturer?
Ask which tablet types they make, how they handle formulas that do not compress well, and how they test disintegration and dissolution. Tablet types can include coated, chewable and effervescent; ask which excipients they would add to your formula. Ask for MOQ and lead time in writing; both vary by manufacturer.
What does NSF/ANSI 455-2 certification mean?
NSF/ANSI 455-2 is a good manufacturing practice (GMP) audit standard for dietary supplements. It is built around the US FDA’s dietary supplement GMP rule (21 CFR Part 111) and adds retailer-driven requirements, so facilities are audited against one harmonised checklist. Certification applies to a specific facility and is listed publicly by the certifier.
What should I ask for in a quote request?
Ask for minimum order quantity, lead times, formulation options, testing and certificates of analysis, in writing. In detail: ask about minimum order quantity (MOQ) per SKU, lead time for a first run and for reorders, whether they offer stock formulas or custom formulation, who sources raw materials, what testing they run (identity, potency, microbiological, heavy metals) and whether you receive a certificate of analysis (COA) per batch, and whether they support the label claims you plan to make. Terms vary widely by manufacturer, so compare written answers rather than assumptions.
How do I verify a manufacturer’s GMP certification myself?
Ask the manufacturer for their current certificate and the exact facility address it covers, then look that facility up on the certifier’s public listing (for NSF/ANSI 455, NSF’s online listings). Certificates apply to specific sites, so make sure the facility that will make your product is the one listed. Each profile here links to the public listing we checked and the date we checked it.
How do I compare tablet manufacturers in California?
Check the facility address and the scope shown on its registry record, then confirm that the proposed work will take place at that site in California. Ask for a written quote with minimum order, testing, packaging, freight and lead times. A company address alone does not establish where your order will be made.
