| Machine type and use | Confirm whether the machine is manual, drop-weight, electronic constant-pull, or another configuration, and whether it supports the intended racket types and stringing workflow. | Model-specific specification sheet, operating manual, and a demonstration using the buyer’s intended racket type. | Machine features and compatibility vary by model; a general product description may not confirm suitability for a particular shop or service. |
| Tension range and settings | Check the stated tension range, units, adjustment increments, supported measurement units, and whether the operating instructions explain the settings. | Technical specification and user manual for the exact model; request clarification for any unspecified tolerance or unit. | Clear specifications help buyers compare equipment and avoid misunderstandings about operating settings. |
| Clamps and mounting system | Confirm the included clamp type and quantity, mounting supports, turntable arrangement, and which parts are included in the quoted configuration. | Parts list, product photographs, and written confirmation of included accessories and optional items. | Accessories may affect setup and usability, and may be priced separately from the main machine. |
| Electrical compatibility | For powered models, verify input voltage, frequency, plug type, rated power, and whether a power adapter or transformer is required for the destination. | Rating-plate image and model-specific electrical specifications. | Electrical requirements differ by destination and model; confirm compatibility before payment and shipment. |
| Calibration and quality checks | Ask how tension is checked, what inspection is performed before dispatch, and whether calibration guidance or service procedures are provided. | Documented inspection checklist, calibration instructions, and any available test record for the shipped unit. | Written procedures make acceptance checks easier and help buyers understand ongoing maintenance needs. |
| Warranty and spare parts | Confirm warranty duration, coverage, exclusions, claim process, service responsibilities, and availability of commonly replaceable parts. | Written warranty terms, spare-parts list, and service contact procedure. | Warranty conditions and after-sales support should be clear before an overseas purchase is finalized. |
| Quotation and order terms | Check model and configuration, quantity, currency, payment schedule, production lead time, quote validity, and the named delivery term and place. | Pro forma invoice or sales contract with specifications and agreed terms stated in writing. | A complete written order record reduces ambiguity about price, delivery responsibilities, and what is being supplied. |
| Freight and packaging | Request packed dimensions and gross weight, packaging details, dispatch point, estimated transit arrangement, and responsibility for freight and cargo insurance. | Packing list, package measurements, shipping quotation, and written confirmation of the agreed delivery term. | Freight cost, handling, insurance, and delivery responsibilities depend on the shipment details and agreed terms. |
| Customs classification and taxes | Ask for a proposed product description and tariff classification, then verify the applicable classification, duties, taxes, and import requirements with the destination-country customs authority or a licensed broker. | Commercial invoice, packing list, country-of-origin details, and any available product information needed by the broker. | Classification and import charges depend on the product and destination; do not assume one tariff code or rate applies everywhere. |
| Regulatory documents | Identify destination-market rules applicable to the specific machine, especially for powered equipment, and verify that any claimed conformity documentation covers the exact model. | Applicable declarations, test reports, labels, or other documents requested by the destination authority or importer. | Requirements differ by jurisdiction and product configuration; confirm them before ordering rather than relying on a generic compliance claim. |
| Pre-shipment acceptance | Agree on how the machine will be checked before dispatch, including model identification, included parts, visible condition, and operation where practical. | Pre-shipment inspection checklist, dated photos or video, and a final packing list. | A documented inspection can help confirm that the ordered configuration is prepared for shipment. |
| Receiving and damage reporting | Ask the carrier and seller about delivery inspection, visible-damage notation, reporting deadlines, and the process for missing or damaged items. | Written claims instructions and shipment documents; photograph the package and contents when receiving the goods. | Prompt documentation supports communication with the seller or carrier if a shipment arrives incomplete or damaged. |
