To maximize ROI, focus on Full Container Load (FCL) shipping, as tiles are heavy and high-volume; LCL (Less than Container Load) significantly increases the risk of breakage and unit shipping costs. Negotiate tiered pricing where a 15-20% discount is often achievable for orders exceeding 3,000 square meters. Additionally, consider the thickness-to-strength ratio; thinner 'slim' tiles can reduce shipping weight and logistics costs by up to 25% without compromising surface aesthetics, provided they meet the required breaking strength.
