What should a B2B buyer include in a pet supplement OEM or ODM brief?

A useful brief identifies the destination market, animal species and life stage, intended product positioning, dosage form, pack size, target cost, forecast volume and launch timing. It should separate desired ingredients from non-negotiable specifications and explain which party will own the formula, artwork and market review. Buyers should also state required testing, documentation, sample stages and approval contacts. This gives the manufacturer enough information to flag feasibility and regulatory questions before pricing or pilot work begins.
