How to Write Rust Prevention, Wooden Case, and Hard Tube Packing into RFQ

Rust prevention should follow the transport duration

Rust prevention should be more specific than saying protect against rust. The RFQ should state shipping method, expected transport duration, storage time after arrival, and environment. Sea freight, air freight, and short local transport need different rust prevention periods.

Wooden case, hard tube, and carton fit different orders

Short parts or small batches may use carton packing. Long parts or higher-risk transport may need hard tube or wooden case. Wooden case fits long-distance and heavy goods, hard tube protects single or small-quantity long parts, and carton fits light standard parts.

Distributor labels and long part support should be confirmed together

Distributor orders should state whether distributor labels, neutral labels, carton marks, carton numbers, and batches are needed. Long part support, end protection, nut fixing, and bending prevention support should be written together with the packing method.

RFQ checklist

Rust prevention: protection method, transport duration, sea freight or air freight, and storage time after arrival.
Packing: carton, wooden case, hard tube, internal fixing, and long part support.
Labels: distributor labels, neutral labels, model, length, quantity, batch, and carton number.
Shipment records: packing photos, label photos, loading photos, and carton mark photos.

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.
