| Product Material | Confirm the base material used for the rack, hooks, screws, and concealed mounting parts. | Common options include 304 stainless steel, 201 stainless steel, brass, aluminum, and zinc alloy. Grade 304 stainless steel is widely selected for humid bathroom environments. | Material certificates, alloy test reports, product drawings, and independent sample inspection. |
| Surface Finish | Evaluate resistance to corrosion, fingerprints, scratching, cleaning chemicals, and color variation. | Typical finishes include polished chrome, brushed stainless steel, matte black, brushed gold, and PVD-coated finishes. | Written finish specifications, coating-process details, salt-spray or corrosion-test results, and production samples. |
| Manufacturing Capability | Check whether production is performed in-house or outsourced, including stamping, casting, welding, polishing, plating, and assembly. | A capable factory should clearly identify its production processes, equipment, quality checkpoints, and subcontracted operations. | Factory audit, process-flow chart, equipment list, workshop photographs, and an approved production sample. |
| Product Range | Determine whether the supplier can provide coordinated bathroom accessories rather than only one towel-rack style. | A broader range may include towel bars, towel rings, robe hooks, toilet-roll holders, shelves, and freestanding racks. | Current catalog, dimensional drawings, finish cards, and matching-product samples from the same collection. |
| Customization Support | Review the supplier’s ability to modify dimensions, mounting systems, finishes, packaging, and logos where legally permitted. | Customization normally requires technical drawings, sample approval, tooling review, and a confirmed minimum order quantity. | Signed drawings, prototype samples, tooling quotations, change-control records, and packaging artwork approval. |
| Minimum Order Quantity | Compare the MOQ for standard items with the MOQ for customized products and special finishes. | MOQs vary by material, finish, packaging, tooling, and production schedule; customized items generally require higher quantities than standard items. | A formal quotation stating MOQ by SKU, finish, packaging type, and order value. |
| Lead Time | Separate sample time, standard production time, customized production time, and shipping time. | Actual schedules depend on product complexity, quantity, finish, raw-material availability, and factory workload. | A written production plan with sample approval date, manufacturing date, inspection date, and dispatch date. |
| Quality Management | Assess incoming-material inspection, in-process checks, final inspection, defect handling, and corrective actions. | A documented quality system should define inspection criteria, sampling levels, tolerances, and nonconformity procedures. | Quality manual, inspection checklist, inspection reports, corrective-action records, and third-party inspection acceptance. |
| Load and Safety Performance | Verify mounting strength, weld integrity, screw quality, wall-plug compatibility, and resistance to repeated use. | Performance depends on design, wall type, installation method, fasteners, and load distribution; no universal load value applies to every rack. | Test method, load-test report, installation instructions, fastener specifications, and approved engineering drawings. |
| Packaging and Drop Protection | Check protection against scratches, deformation, moisture, and movement during container or parcel transport. | Suitable packaging commonly includes individual bags, protective films, molded inserts, cartons, and export pallets where required. | Packaging specification, carton dimensions, drop-test results, loading photographs, and barcode or labeling samples. |
| Export Documentation | Confirm the supplier can provide accurate commercial invoices, packing lists, shipping documents, and product information. | Documentation requirements vary by destination, product classification, packaging, and buyer’s customs procedures. | Sample invoice, packing list, HS-code proposal, country-of-origin information, and destination-market compliance documents. |
| Commercial Terms | Compare quotation validity, payment terms, Incoterms, tooling charges, sample fees, warranty, and replacement policy. | The final landed cost includes product price, packaging, tooling, inspection, freight, insurance, duties, and local delivery. | Signed quotation, pro forma invoice, warranty terms, payment schedule, and a total-cost comparison sheet. |
| Supplier Verification | Confirm the supplier’s legal identity, production address, export capability, ownership of certificates, and consistency between documents and factory operations. | Online information alone is not sufficient; independent verification is recommended before a large purchase or long-term agreement. | Business license, factory audit, certificate-validation records, reference orders, video inspection, and pre-shipment inspection. |
