Manufacturing lead time in China: from RFQ to your dock

Lead Time · China Manufacturing lead time in China: from RFQ to your dock Lead time is not one number — it is a chain of stages, and a single missing document or long-lead part can stall the whole thing. This guide maps the realistic brackets, the holidays and customs that bite, and the moves that genuinely compress the clock. Request a quoteThe stages The stages, and their brackets A typical order moves through: RFQ response (hours–days), DFM feedback (days), prototype (days–weeks), tooling if needed (weeks), production (weeks), and shipping plus customs (days–weeks). The part you can control most is the first — a complete RFQ with drawing, quantity and finish turns around fast; a bare model waits while questions are answered one at a time. How NPI sequences these stages. Prototype vs production timing A CNC prototype can ship in days because there is no tool. A PCBA prototype follows the component lead times — if every part is in stock, days; if one is long-lead, the clock starts there. Mass production adds tooling and queue time, but the dominant variable is still components and documentation readiness, not the machines. CNC timing. Electronics timing. What blows up the clock Missing documentation. No tolerance notes, no finish spec, no BOM — each costs a round-trip. Long-lead components. A single 20-week part sets the production date regardless of everything else. Chinese New Year. The whole country shuts for 1–2 weeks (often longer in effect); orders before and after pile up. Plan around it or pay the wait. Customs and shipping. A smooth airway bill is days; a held shipment is unpredictable. Correct paperwork prevents most holds. Golden Week and regional holidays. Smaller but real local shutdowns.

The binding constraint is almost always documentation readiness and component lead time, not machine capacity. Lead time composition: the three blocks A quote like “two weeks” hides three independent blocks. Pre-production is everything before metal moves: RFQ response, DFM feedback, prototype and any tooling. Production is the run itself plus the queue ahead of it. Post-production is finishing, first-article inspection, packing, freight and customs. The block that bites you is rarely the machine — it is usually pre-production documentation or a post-production customs hold, and those are the two you actually control. On a Dongguan floor those brackets resolve into a concrete three-tier model. A fast prototype is a single part with no tool and few process steps; a standard order is a documented small batch with a standard finish; a complex or volume order adds the process depth and finishing that only a mature shop absorbs without pulling in a second vendor. The tiers below describe a no-MOQ partner — the minimum order is one piece. TierRealistic windowWhat sets it Fast / prototype~3 daysSingle piece, no tool, in-stock material, minimal process steps Standard order~7 daysSmall batch, complete drawing, standard anodize or passivation Complex / volume~30 days10–20 process steps, surface treatment, tooling or a deep queue These are planning brackets from a Dongguan facility, not commitments. The binding constraint is part complexity and process-step count; any surface treatment pushes an order into the 30-day tier. Urgent work has shipped in as little as one day when the package was complete and the material was on hand. What actually moves the number The brackets above are outcomes. The inputs that shift them are few and predictable, and they line up with what a shop floor actually experiences: Process-step count. A simple bracket is cut and done; a complex machined housing can run 10–20 steps — each setup, in-process check and handoff adds a slice. More steps means a longer clock, full stop. Surface treatment. Anodizing, plating, heat treatment and coating are post-machining operations. On this floor, a product that needs finishing is the canonical 30-day case, because the finish is a second process chain bolted onto the run. Component lead time. For electronics, a single long-lead IC or connector sets the production date no matter how fast the line is. This dominates any bracket you are quoted. Documentation readiness. A drawing with tolerances, finish spec and BOM turns around in one round; a bare model waits while questions are answered one at a time. Holidays and capacity. Chinese New Year closes the country for 1–2 weeks with backlog before and after; Golden Week and regional shutdowns add smaller but real gaps. A full queue ahead of your order is its own variable. The planning takeaway is blunt: the machine is rarely the constraint. Complexity, finishing and components are. Spend your energy there and the quoted window becomes real. A useful mental model is to treat every bracket as “documentation plus components, then machines” — if the first two are settled, the third is almost never what costs you the week. How to compress the clock Send a complete RFQ. Drawing with tolerances, finish, quantity, target date — one round, not five. Use a no-MOQ partner. Order exactly what each stage needs instead of waiting to accumulate volume. Why MOQ slows you down. Second-source long-lead parts during NPI. So a shortage never sets the production date. Plan around CNY. Place orders with the holiday buffer built in, or accept the wait. Parallelize. Run DFM feedback and component sourcing at the same time, not in series. Why a no-MOQ partner compresses your clock A minimum order quantity is a hidden lead-time tax. A shop with a 500-piece MOQ forces you to wait until you can fill a batch before anything moves — at every gate of development. A no-MOQ partner (minimum: 1 piece) lets you order exactly what each stage needs and keep moving instead of batching to hit a floor. In practice that means ordering five parts at EVT, fifty at DVT, five hundred at PVT, and only then committing to volume — with the same partner carrying the learning across every gate. The NPI path, EVT to MP. You never lose a week accumulating volume you do not yet need, and you qualify the process on real parts before the run. The compression is largest at prototype and low-volume stages, which is exactly where launch risk lives. With a one-piece minimum, the cheapest possible test of a shop is a single part. Logistics and customs: the tail you can control The part is only “done” when it clears your dock. Dongguan sits inside the Greater Bay Area, roughly an hour from Shenzhen’s Yantian and Shekou ports, Guangzhou’s Huangpu, and Hong Kong airport — with a dense field of freight forwarders who file export documentation daily. That geography shortens the tail: a part cut, finished and inspected in Dongguan is consolidated for ocean or air without a second inland transit leg. For the crossing itself, the lever is paperwork. A clean airway bill and declaration clear in days; a missing HS code, valuation or certificate turns the same shipment into an open-ended hold. Air freight typically lands in 3–10 days; ocean is cheaper and slower by weeks. Build the documents during production, not after it — the hold always starts where the paperwork stopped. Tariffs and what they change. Capacity on the floor: the queue you cannot see Brackets assume the shop actually has a machine free when your order arrives. They do not, when the floor is saturated — and a full queue ahead of you is the quietest way to miss a date. Capacity is the honest signal of lead-time risk, which is why it is worth naming in numbers rather than adjectives. A Dongguan facility running EMS and CNC under one roof carries 80+ production machines (50+ 3-axis mills, 20+ 4-axis and 20+ 5-axis mills, 25+ CNC lathes, 7+ grinders) and 100+ cross-trade technicians across a 6,800 m² plant established in 2006. Run as a production system rather than a jobbing corner, it ships 1,000,000+ parts a year for 100+ domestic and overseas customers. The practical effect on your schedule: a deep, balanced machine pool absorbs a rush without pushing your slot to the back of a thin queue, and first-article control — CMM inspection and SPC at Cpk ≥1.67 for critical characteristics, ≥1.33 for general — keeps the run moving instead of stopping for rework. None of this shortens the document and component constraints; those are still yours to solve. But it removes the most common “we are booked” surprise, which is exactly the variable a far-away shop is least able to show you before you have committed. Why location helps In Dongguan, the processes a product needs — PCB, SMT, CNC, finish, box build — are within an hour of each other. That density removes the logistics tail between sub-suppliers that quietly adds weeks in fragmented supply chains. A single partner running EMS and CNC under one roof collapses even more handoffs. The Dongguan advantage. Buyer’s checklist: compress the schedule A lead time is mostly a function of your own preparation. Run this list before you send the RFQ: Ship a complete package. Drawing with tolerances, finish spec, BOM, quantity and target date — one round, not five. Name the long-lead parts. Flag any IC or component over a few weeks and second-source it during NPI, so a shortage never sets your date. Pick a no-MOQ partner. Order the exact quantity each gate needs; stop batching to hit a minimum. Plan around CNY. Place orders with the holiday buffer built in, or accept the wait — do not discover it in week three. Parallelize. Run DFM feedback and component sourcing at once, not in series. Source EMS + CNC in one building. In Dongguan, a partner running both under one quality system removes the enclosure-vs-board handoff that quietly adds weeks. The Dongguan advantage. The one move that matters mostIf you do nothing else: send a complete, ready-to-build package to a no-MOQ shop inside the Dongguan cluster. Documentation readiness and local supply-chain density remove more lead time than any negotiation on the machine rate — and they are free. Air vs ocean freight: picking the mode at the tail Once the part is built, the last block is freight, and the mode is a cost-versus-clock decision, not a default. Air freight lands in roughly 3–10 days and wins for prototypes, small high-value builds and anything your launch date depends on — the premium is real, but it buys the days that matter most at EVT and DVT. Ocean freight is far cheaper per kilogram but slower by weeks, and it suits volume runs where the schedule has slack and the cost of a container spreads across thousands of units. Between them sit air consolidations and express services for the handful-of-boards cases that are too urgent for ocean and too light to justify a full air booking. The rule that usually holds: match the mode to the stage. Fly prototypes and first articles; ship production. Fly again for any late-stage change that would otherwise strand a committed production date — the air premium is almost always cheaper than the cost of missing a launch. Decide the mode when you place the order, not when the goods are packed, because the mode changes how you schedule the finish and the documentation. A worked timeline: where the 30 days actually go To make the brackets real, follow a complex order day by day. Assume a machined enclosure with anodizing and a small PCBA, ordered as a complete package. Days 1–3: RFQ response and DFM feedback, with any tolerance or finish question resolved in one round. Days 4–10: CNC machining and first-article inspection on the CMM, running parallel with component procurement for the board. Days 11–18: anodizing and any surface treatment, then the SMT build and test of the board. Days 19–26: box build, functional test, and the full documentation package assembled while the goods are packed. Days 27–30: export filing, freight and handoff to the forwarder. A rush version of the same order, with material on hand and no finish, collapses toward the 3-day tier — which is why a complete package and early component sourcing matter more than any machine-speed claim. Safety stock and buffer strategy: de-risk the schedule you cannot shorten Some lead time cannot be compressed — a custom connector, a long-lead IC, a finisher with a fixed queue. For those, the lever is not speed but buffer. Carry safety stock on the few parts that would otherwise set the date; agree a vendor-managed inventory program for steady-demand products; and order the long-lead items the moment the design is stable, not when production is scheduled to start. Buffer is expensive if you spread it across the whole BOM and cheap if you concentrate it on the two or three parts that actually gate the schedule. The discipline is to name those parts at the sourcing review, not to discover them the week they go on allocation. Chinese New Year: the calendar that moves your date Chinese New Year is the largest single schedule risk on the calendar, and it is predictable years in advance. The official holiday runs a week or so, but in practice the effect spans a month: factories wind down for staff travel before the break and ramp back up over one to two weeks after, with a backlog on both sides. Orders placed in the two weeks before the break can wait three to four weeks in real terms, and quality on the last shifts before shutdown deserves a closer first-article look. The fix is planning, not pressure: place the order with the holiday buffer built in, avoid scheduling first builds into the pre-holiday rush, and confirm the exact holiday dates with your supplier at the start of the year rather than the week before. Golden Week in early October and regional shutdowns are smaller versions of the same effect. When to pay for speed — and when not to Expedite fees are a tool, not a reflex. The time to pay for speed is when a day of lead time is worth more than the expedite premium: a launch date, a trade show, a customer deadline, or a late-stage change that would otherwise strand inventory. The time not to pay is when the bottleneck is documentation or a long-lead component — an expedite on the machine does not shorten a 20-week IC, so the money is wasted. The test is simple: find the real constraint first, then spend on it. Usually that means expediting the component, not the assembly, and paying the air freight, not the machine-rate rush fee. Partial shipments and consolidation: ship what is ready Lead time is not all-or-nothing. A mixed order — a few fast machined parts and one slow board — does not have to ship as one lot. Splitting it lets the fast parts arrive and be tested while the slow board finishes, which effectively pulls your schedule forward by the difference. The same logic applies in reverse with consolidation: grouping several small orders into one shipment saves freight and paperwork, at the cost of waiting for the slowest item. The decision is a simple trade-off between clock and cost, and a partner that offers both — partial shipments when speed matters, consolidation when cost does — gives you the lever instead of a single shipping date you cannot move. Frequently asked questions How long does Chinese manufacturing take?It is a chain: RFQ (hours–days), prototype (days–weeks), tooling if needed (weeks), production (weeks), shipping plus customs (days–weeks). The binding constraint is usually documentation readiness and component lead time, not machine capacity. What slows down a China order most?Missing documentation, a single long-lead component, and Chinese New Year. Each can add weeks. A complete RFQ and second-sourced critical parts remove most of the risk. How does Chinese New Year affect lead time?The country largely shuts for 1–2 weeks, with knock-on backlog before and after. Orders placed without the holiday buffer can wait a month or more. Plan the calendar around it. Can a prototype ship fast?Yes — a CNC prototype with no tool can ship in days; a PCBA prototype follows component lead times and ships in days if all parts are in stock. The faster path is a complete, ready-to-build package. Does a no-MOQ partner speed things up?It removes the wait to accumulate volume at each stage, so you order exactly what each gate needs and keep moving. It compresses the clock most at prototype and low-volume stages. Can you give a firm lead time?Send the drawing or BOM and target date to [email protected] — we will return a staged schedule with the binding constraint called out, so you know what actually sets the date. What are your real lead-time tiers?Three tiers from our Dongguan floor: roughly 3 days for a prototype, 7 days for a standard order, and 30 days for complex or volume work — set by part complexity and process-step count, where complex parts run 10–20 steps. The minimum order is 1 piece, so you can qualify the shop on a single part before scaling. Does surface treatment change the lead time?Yes. Finishing — anodizing, plating, heat treatment, coating — is a second process chain after machining, and on this floor a product that needs it is the canonical 30-day case. Flag the finish early so it is planned into the schedule, not discovered after the run. How close is the factory to the port?Our Dongguan facility in Hengli Town is about an hour by road from Shenzhen’s Yantian and Shekou ports, Guangzhou’s Huangpu, and Hong Kong airport, with freight forwarders filing export documents daily. Finished goods ship within days, not after a long domestic haul. Should I ship by air or ocean?Match the mode to the stage: fly prototypes and first articles (about 3–10 days), ship production by ocean to save cost. Fly again for a late-stage change that would strand a committed launch date — the air premium is usually cheaper than a missed launch. Can I split a shipment to get the fast parts first?Yes. A mixed order does not have to ship as one lot — we can send the fast machined parts ahead while a slow board finishes, and consolidate later to save freight. The trade-off is clock versus cost, and you get the lever instead of a fixed date. Sources & coverage note: Lead-time brackets are our own planning ranges for machining, EMS and consolidated freight, not carrier commitments; customs timelines follow US HTS and destination-country procedures and vary by port and season. Verify with your forwarder before quoting customers.
