How to Confirm Ball Screw Quotation Validity and Payment Terms

Write quotation validity clearly

Ball screw quotation validity is usually linked to material price, exchange rate, stock status, and machining schedule. Before ordering, confirm whether the quotation validity still applies instead of paying from an expired quotation.

Payment terms affect production scheduling

Payment terms should state deposit ratio, balance timing, payment before shipment, split payment acceptance, and bank fee responsibility. End-machined or custom parts usually start after payment and drawing approval.

Quantity change needs reconfirmation

If quantity change, model mix, or nut quantity changes, unit price, packing, freight, and lead time may also change. Batch orders should reconfirm quantity and delivery batch for each model.

Freight and lead time should not be assumed unchanged

Freight depends on destination country, packing volume, long-part length, and shipping method. Lead time may be recalculated because of stock, cut length, end machining, inspection report, or packing request.

Typical buyer situations

This topic usually appears in distributor stocking, repair replacement, machine retrofit, automation projects, and drawing-based purchasing. If a buyer sends only one model number, the supplier cannot judge the real use, packing risk, or whether machining upgrades are needed.

Details to confirm before quotation

To reduce repeated questions, the RFQ should cover product specification, use case, and delivery expectations together. The following points can be copied into the RFQ form or email.

Purchase purpose: distributor stock, repair replacement, machine project, or sample testing.
Specification: diameter, lead, overall length, thread length, nut type, and quantity.
Machining: cut-to-length, end machining, and whether BK/BF, FK/FF, EK/EF, or other supports must be matched.
Delivery: target quantity, expected lead time, packing, labels, shipping method, and whether shipment photos are required.

Common mistakes

A common mistake is asking only for unit price without application, quantity, or packing details. Another is sending photos without dimensions. This turns quotation into guesswork and can create errors in end machining, nut matching, or long-part shipping.

Next step

If the specification is clear, submit an RFQ directly. If the model or accuracy grade is still uncertain, describe the machine use and old part details so the supplier can recommend a standard part, bar stock, cut-to-length, or end machining route.
