Pricing starts with specifications, not the catalogue photo. A basic one-piece toilet may cost less, but rim design, ceramic thickness, flushing system, seat quality, and water-efficiency testing change the final quotation. The World Bank’s 2023 Logistics Performance Index shows that customs, infrastructure, and shipment reliability strongly affect landed costs. Request FOB and CIF prices separately. Include packaging, spare parts, inspection, and documentation. Small omissions become expensive.

Customization is possible, but every change needs technical confirmation. Buyers should check rough-in distance, inlet position, trapway size, glaze colour, carton strength, and local certification requirements. A mould change can require new tooling and longer production time. Ask for a pilot order. It exposes problems early. Do not trust only a digital sample. A physical flushing test is more useful.

Shipping needs careful calculation. Box dimensions often matter more than product weight because toilets consume container volume. A 40-foot high-cube container may hold roughly 200–300 boxed units, depending on packing design. UNCTAD’s Review of Maritime Transport has documented continuing freight-rate and schedule volatility, so shipment dates should include contingency time. Supplier selection should include factory audits, batch inspection records, export experience, and clear warranty terms. I would also compare rejection rates, not just the lowest unit price. The cheapest offer can be the least economical.
