When choosing a portable metal tool box supplier in China, pricing deserves careful checking. A low unit price may exclude tooling, export packaging, inspection, or inland transport. Compare complete quotations, not attractive headline figures. Ask about steel thickness, surface treatment, drawer slides, locks, handles, and load capacity. Details matter.
Customization usually affects both cost and timing. Buyers can request dimensions, colors, logos, foam inserts, tray layouts, and locking systems. Start with the sample. A physical sample reveals sharp edges, weak welds, uneven paint, or difficult drawer movement. Confirm whether sample fees become refundable after a production order. Also check the minimum order quantity and tooling ownership. I have seen projects delayed because a small logo change required new artwork approval.
Shipping needs more than a freight estimate. Confirm carton size, gross weight, pallet requirements, shipping terms, port handling, and insurance responsibilities. Sea freight is often economical for larger orders, while urgent samples may need air transport. Shipping changes everything. Build extra time for production checks and customs documents. A pre-shipment inspection can verify quantities, dimensions, packaging, and visible defects before release. However, inspection cannot replace clear specifications. That is where buyers sometimes fall short. They approve a drawing, then expect details that were never written. A reliable supplier should explain limitations, provide production updates, and show consistent quality records rather than making broad promises.
