Questions buyers ask
How do I choose a pet supplement manufacturer in the USA?
Start with the USA list, check the exact facility and its certificate scope, and confirm dog supplement manufacturing and private label pet supplements. 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 pet supplement manufacturer?
Ask which facility makes the pet products and whether it is the certified one, which formats they make (chews, powders, liquids or tablets), which animals they formulate for, and how they support the label claims you plan to make. Check the rules for animal products in each market you sell in.
Do you verify that these companies make pet supplements?
No. A company is listed here when one of its facilities is on a public registry we check and either its USDA Organic certificate lists pet supplement items or its own website says it makes pet supplements. The USDA Organic item list is the certifier’s record of what the operation is certified to handle organically, as we found it in the USDA Organic Integrity Database on the date shown; it covers organic items only and is not a test of any product. A website claim is the company’s own statement: we keep the quote, the page and the date we checked. Each card says which applies. Confirm either with the manufacturer before you rely on it.
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.
