The first wire transfer is where an import project stops being research and becomes risk. What the 30/70 structure actually protects, why sample approval must precede the deposit, and how inspection, documents and credit instruments divide the exposure.
Quantity, material grade and packing each carry their own cost logic. How the tiers are built, which hidden variables separate two comparable quotes, and how to negotiate inside the structure instead of against it.
Minimum order quantities are not a marketing number. They fall out of sheet utilisation, press sizes, lacquer line changeovers and carton economics — and every one of those is negotiable once you understand which lever your order pulls.
