Buyer questions
Practical answers before sending an RFQ.
Can undercarriage parts be quoted from machine model only?
Machine model helps, but part numbers, item photos, and item mix reduce mismatch risk, especially for similar model variants.
Can one RFQ include several crawler models?
Yes. Separate the requested part number, item type, and quantity for each model so the factory review can be accurate.
Are lead times fixed for undercarriage items?
Lead time depends on model mix, stock status, production batch, and packing scope, so it is confirmed after manual review.
Quote review
Send model, drawing, material, quantity, and destination details.
Final price, samples, lead time, payment terms, and compliance details are confirmed manually after factory review.
