Lead Time and Shipping for CNC Parts from China

By CHX Metal Engineering Team · Published 2026-10-09

How lead time is built for CNC parts from China - quotation, material, machining, finishing, inspection, packing - plus shipping and Incoterms for the US/EU. Parts are machined from aluminium, stainless steel, brass, titanium and engineering plastics.

Lead time is not one number - it is a short sequence of steps, each with its own duration and its own risk of delay. Understanding the sequence lets you plan production instead of reacting to it, and it makes a supplier's quote easier to judge.

How lead time is built

1. Quotation and DFM. Usually the same day to a couple of days, depending on drawing quality and how much feedback is needed.
2. Material. Common grades are in stock; unusual sizes or grades are ordered in, which can add days.
3. Machining. The cycle time of the part times the batch size, divided across the machines running it.
4. Finishing. Anodizing, plating or heat treatment adds a step, sometimes with a batch-processing queue.
5. Inspection. Standard checks are quick; a full CMM layout on every part of a batch takes longer.
6. Packing and freight. Export packing, then the chosen shipping mode.

Typical durations

As a working baseline, prototypes typically ship in 3-7 days and production batches in 7-15 days after drawing approval. Where surface treatment is involved, add about 5-10 days for the finishing and its queue. These are working numbers, not guarantees - an unusual material, a very tight tolerance, or a design that is still iterating will move them, and a supplier should tell you when that is the case.

What delays a job

• Drawings that are incomplete or internally inconsistent - the clock only really starts once the revision is fixed.
• A late change of material or finish, which resets material or finishing lead time.
• Tolerances that turn out to need a process the shop did not plan for, forcing a re-route.
• A first-article inspection that fails on a dimension nobody flagged, which is why DFM feedback matters upstream.
• Shipping congestion, customs queries or an incomplete commercial invoice.

Shipping modes and when to use them

• Express courier (typically 3-7 days door-to-door). Best for prototypes and small batches where speed outweighs freight cost.
• Air freight (typically around a week door-to-door). A middle option for medium batches or time-sensitive production.
• Sea freight (weeks, plus port handling). The economical choice for large or heavy production orders where you can plan around the transit time.

The right mode is a planning decision, not a default: match it to how much you are shipping and how soon you need it.

Incoterms in plain terms

• EXW (Ex Works) - you take responsibility from the factory gate; maximum control, maximum work on your side.
• FOB (Free On Board) - the supplier delivers to the export port and clears export; you handle the main freight and import.
• DAP (Delivered At Place) - the supplier delivers to your address, but you are the importer of record and pay duty and taxes.
• DDP (Delivered Duty Paid) - the supplier delivers to your address with duty and taxes settled; simplest for you, and it should be quoted explicitly because duty rates vary.

Whichever term is used, make sure it is stated on the quotation, because it changes both the price and who is responsible for each step.

Packaging and documentation

Export packing should protect the parts and survive the transit mode. Ask how parts are protected against corrosion and impact, how they are counted and labelled, and whether the packaging suits your incoming inspection.

For customs you will normally need a commercial invoice, a packing list, and a description that matches the goods accurately. Getting the description right at the invoice stage avoids customs holds that can add days to a delivery.

Planning advice for US and EU buyers

• Plan the freight mode at the same time you place the order, not after the parts are made.
• Keep a small buffer on the first order from any new supplier, then tighten it as the process proves out.
• For recurring parts, ask about running a small safety stock or a kanban-style release so production is not exposed to a single shipment.
• Lock the drawing revision before production starts; a late change is the most common cause of a slipped date.

At CHX Metal, prototypes ship in 3-7 days and production batches in 7-15 days, with export packing and shipping arranged as part of the order, so the part and its logistics move on one schedule.

Frequently asked questions

How long does it take to get CNC parts from China?

Prototypes typically ship in 3-7 days and production batches in 7-15 days after drawing approval, plus about 5-10 days where surface treatment is required. Transit time then depends on the shipping mode.

What shipping method should I use?

Express courier suits prototypes and small batches; air freight suits medium or time-sensitive batches; sea freight is the economical choice for large or heavy orders where you can plan around the transit time.

What Incoterm should I choose?

FOB gives you control of freight; DDP is the simplest for you but should be quoted explicitly since duty rates vary; DAP leaves you as importer of record. Match it to how much you want to manage.

Can you ship to the US and EU?

Yes. We ship worldwide, including the United States and the European Union, with export packing and shipping arranged as part of the order.
