Manufacturing
What is the difference between OEM, ODM and CDMO?
These are commercial service descriptions whose practical scope varies by supplier. Clarify who owns the formula and design, who develops and manufactures the product, and which party handles testing and documentation. A service acronym does not establish licenses, capacity or regulatory responsibility. Put the actual work and deliverables in the agreement.
Read the answer & sourcesWhich supplier documents should I request?
Request the legal entity, relevant facility and product documentation, formula version, raw-material specifications, batch traceability, test scope, packaging information and the basis for shelf life. Verify issuer, scope, validity and product identifiers. The needed documents depend on the product and target market; one generic certificate is not a complete qualification.
Read the answer & sourcesCan I assume a manufacturer minimum order quantity?
No. Minimum order quantities depend on the supplier, formula, packaging, printing and order conditions. Record only a current published or directly confirmed quotation, including its date and assumptions. This directory does not invent MOQs, prices, production capacity or lead times for listed businesses.
Read the answer & sourcesHow does formula mass balance work?
Add the specified ingredient masses and compare the sum with the target filling mass on the same basis. The remainder is unassigned mass, not an automatically chosen carrier. A balance using incomplete quantities remains incomplete. Our tool checks arithmetic and highlights over-allocation; it does not approve ingredient selection, stability or manufacturing suitability.
Read the answer & sourcesShould I copy a competitor ingredient list?
A public list can support category research, but it does not reveal the full formula or confer permission to copy protected branding, confidential information or product materials. Develop and document your own specification, then verify the relevant ingredients, claims and market requirements. Ingredient order alone is insufficient for a production recipe.
Read the answer & sourcesWhat do overages mean in formulation?
An overage is an intentional amount above a target declaration under a documented rationale. It must not be assumed from a label-to-test difference. The relevant ingredient, assay, process losses, stability data and market rules need assessment. This site does not calculate automatic overages or treat extra active content as inherently better.
Read the answer & sourcesWhat should support a shelf-life claim?
Ask for data on the actual formulation and final package under stated storage conditions, with defined methods and acceptance criteria. Ingredient certificates or another product’s shelf life are insufficient substitutes. Document how changes to material, flavor, process or package affect the evidence and the approved specification.
Read the answer & sourcesWhat is batch traceability?
Traceability links a finished batch to relevant material lots, production and packing records, specifications, test results and distribution records. A batch code on a can is useful only when the supplier can connect it to those records. Keep document versions and sample identifiers when comparing a certificate with a delivered product.
Read the answer & sourcesCan a facility certificate certify every product?
A certificate has a named subject, scope, issuer and validity period. A facility-related certificate does not automatically establish the composition, clinical efficacy, registration or batch compliance of every product made there. Check the certificate itself and obtain the separate documents relevant to the product and intended market.
Read the answer & sourcesHow should a pouch sample specification be written?
Identify formula and drawing revisions, filling mass and tolerances, wrapper material, finished dimensions, seam details, package, pouch count, test methods and acceptance criteria. Separate confirmed values from development targets. A photograph or a size label is useful context but cannot replace the written and measured specification.
Read the answer & sourcesHow do I calculate cans and cartons?
Use the requested pouch quantity, verified pouches per can and cans per carton, rounding up at each packaging level where full units are required. Any planned scrap or reserve percentage is an explicit assumption. The packaging calculator handles those counts; factory yield, capacity, freight and final commercial packing still require confirmation.
Read the answer & sourcesDoes a food-contact declaration cover the whole package?
Check exactly which material, component, use conditions and jurisdiction the declaration covers. A statement about the base resin does not necessarily document a liner, colorant, adhesive or the complete closure. Keep the issuer and revision with the package specification, and request relevant supporting tests for the intended contact conditions.
