Long Island and the wider East Coast are crowded with supplement contract manufacturers. Buyer-intent search surfaces private-label catalogues, NSF claims and facility tours — useful background that still leaves the RFQ incomplete. Before you award a custom formula or private-label run, lock the commercial and quality details in writing. The checklist below is what Zenith asks East Coast brand teams to confirm with every co-man, including us.
1. Scope the dose form and ownership
State whether you need custom formulation, a private-label stock formula, or full contract manufacturing of your existing recipe. Confirm who owns the finished formula, artwork and batch records, and that finished goods ship under your brand with no manufacturer branding on the pack. Zenith’s model is explicit: you control actives, doses, dose form, pack format and artwork; we control specification qualification, batch records and release documentation through an FDA-registered, cGMP (21 CFR Part 111) partner network.
2. Put MOQs and timelines on the quote
Ask for unit and powder minimums separately. Zenith’s published programme starts at 3,000 units for capsules, tablets and tinctures (liquids), and 500 kg for bulk powder blends. First bench sample is typically 10–15 working days from a written brief; a production run is typically 4–6 weeks from artwork approval. If a competitor quotes “startup-friendly” without those numbers, treat lead time as unknown.
3. Map dosage forms you actually need
Confirm capability for the forms on your roadmap — not a generic “we do supplements” claim. Zenith runs capsules, tablets, powders, tinctures (liquids), sachets, stick packs and bulk blends, plus custom blending/milling, packaging/labelling and empty-capsule supply into the same project conversation.
4. Demand the document pack before PO
Every serious RFQ should name the release pack: lot-specific COA, SDS, specification sheet, stability data where claimed, and full lot traceability. A marketing PDF is not a COA. Align allergen, GMO and any Kosher/Halal claims with what will appear on your label before artwork freezes.
5. Connect ingredient stock to the fill date
East Coast launches slip when actives are “US stock” with no city, or when empty capsules arrive on a different clock than the blend. Zenith holds bulk nutraceutical ingredients and primary packaging in Ronkonkoma, Long Island, New York, with typical stocked-ingredient ship windows of 3–7 business days after a cleared order (made-to-order programmes take longer). For many powders the ingredient MOQ is 25 kg. Asking one technical team for both the active and the fill reduces hand-offs.
6. Score the RFQ before you award
- Written MOQ by dose form and by bulk blend
- Sample timeline and production timeline from a fixed milestone (brief / artwork approval)
- Facility registration and cGMP framework named (FDA-registered; 21 CFR 111)
- Document list that matches release, not brochure claims
- Named warehouse city for critical inputs and empty capsules
- Clear ownership of formula, artwork and finished goods
Send dose form, target label claims, estimated first run size and any existing COA or competitor sample. We will confirm feasibility, propose a development path when needed, and quote sample plus production timelines against the published programme.
