MOQ is usually driven by transport economics and packaging. Bulk tanker deliveries often require a minimum full load to justify freight, while drums and IBCs have lower MOQ but higher unit cost. Constraints include availability of heated or insulated tankers, delivery lead time during peak season, and the buyer’s ability to store the emulsion within temperature limits. Shelf life and batch age matter, so long transit or warehousing can reduce usable life. Some suppliers require returnable containers or charge cleaning fees. Contracts should define delivery windows, sampling rights, and rejection handling.
