When importing welding parts from Vietnam, how should I plan my procurement schedule in advance to account for public holidays like the Lunar New Year?

We often see clients panic when their welding frames get stuck in Hai Phong port during February Hai Phong port ¹. Missing critical project milestones because of foreseen holidays is painful and preventable.

To avoid disruptions from Vietnam’s Lunar Lunar New Year ² New Year, finalize your welding part orders by early November, aiming for a shipping deadline three weeks before Tet. This schedule accounts for the typical 10-day factory shutdown, pre-holiday labor shortages, and severe logistics congestion at major ports like Cai Mep.

Let’s break down the exact timeline and strategies needed to keep your supply chain moving.

How many weeks in advance must I confirm my welding parts orders to beat the Vietnam Lunar New Year shutdown?

Our local team in Vietnam spends weeks securing production slots before the holiday rush hits Катлай ³. Without early confirmation, your custom metal orders risk indefinite suspension until March.

Confirm orders at least 10 to 12 weeks before the Lunar New Year begins. Since Vietnamese factories face high labor turnover and raw material shortages a month prior to the holiday, locking in production by mid-October ensures your goods depart before the logistics freeze.

Planning your procurement schedule for Vietnam is significantly different from sourcing in Western nations because of the fluidity of the Lunar New Year (Tet). Unlike the fixed Gregorian calendar, Tet shifts annually Gregorian calendar ⁴, generally falling between late January and mid-February. For importers of custom welding parts, this means the "danger zone" for production delays shifts every year.

When we manage supply chains for our clients, we treat Tet not just as a week-long holiday, but as a six-week disruption event. The disruption begins well before the first official day off. Suppliers stop accepting new orders for pre-holiday delivery as early as December. If you need complex aluminum frames or steel structures delivered to the US by February, placing an order in December is often too late. By then, raw material suppliers are already winding down, and production slots are fully booked by domestic buyers trying to stock up.

To help you visualize the necessary lead times, we have developed a standard procurement timeline. This schedule assumes a typical Lunar New Year start date in early-to-mid February, which is common. You must adjust the specific dates based on the actual lunar calendar for the specific year (e.g., 2026 or 2027), but the intervals remain constant.

Critical Procurement Milestones for Welding Imports

Beyond the timeline, financial planning is crucial. Vietnamese factories often require significant cash flow to secure steel and aluminum before the holiday. If you delay your deposit, the factory may reallocate your raw materials to a paying domestic customer. We always advise our clients to clear payments promptly in Q4 to ensure their production run takes priority.

What specific risks does the pre-holiday rush pose to the quality control of my custom metal fabrication projects?

We have witnessed rushed welding seams fail inspection because factories prioritized speed over precision. Ignoring the pre-holiday quality dip can ruin your entire assembly line.

The weeks preceding Tet carry a high risk of welding defects due to worker fatigue and rushed production schedules. To mitigate this, you must schedule third-party NDT inspections 15 days before the shutdown and strictly forbid any production activities during the volatile final week.

Quality control is the first casualty of the pre-holiday rush. In the metal fabrication industry, welding requires a steady hand, focus, and adherence to strict procedure specifications (WPS). procedure specifications ⁵ However, the atmosphere procedure specifications (WPS) ⁶ in Vietnamese industrial zones changes drastically in January. Workers are anxious to return to their home provinces, often booking tickets weeks in advance. Management pushes for higher output to clear backlogs, leading to extended overtime shifts.

Fatigue is a major enemy of quality welding. quality welding ⁷ When welders work 12-hour shifts to meet deadlines, the incidence of defects like porosity, undercut, and lack of fusion increases. For custom parts like the aluminum frame shown above, aesthetic finish is also critical. aluminum frame ⁸ Rushed grinding and polishing can lead to uneven surfaces or scratches that would normally be rejected. Furthermore, during this period, factories often utilize temporary labor to fill gaps left by early departures. These temporary workers may not be familiar with your specific quality standards.

Common Pre-Holiday Welding Defects and Causes

We utilize a strict audit protocol during this season. We specifically look for these issues which spike in frequency during the "Tet Rush."

To protect your interests, you must enforce a "Quality Cut-Off" date. We recommend stating in your contract that no critical welding or finishing steps can occur in the final 7 days before the factory closes. That final week should be reserved exclusively for packaging and loading. If fabrication is pushed into that final week, the likelihood of receiving a container full of reworkable parts skyrockets. Additionally, third-party inspection agencies are often fully booked. You must schedule your inspectors at least a month in advance to ensure they can visit the factory before the shutdown.

How should I adjust my inventory buffer to cover the extended factory closures during Vietnam's Tet holiday?

Our warehouse managers always advise clients to stockpile critical consumables before January. Running out of stock while factories are closed creates unnecessary financial bleeding.

Increase your inventory buffer by 20% to 30% to bridge the four-week gap caused by the holiday shutdown and the slow post-Tet ramp-up. Analyze your sales velocity for Q1 and secure stock of long-lead items like custom aluminum tubing well before December.

Many importers mistakenly believe they only need to cover the 7 to 9 official days of the Tet holiday. This is a dangerous miscalculation. In reality, the production gap is much wider. While the official government holiday might last just over a week, the industrial reality is different. Factories often stop production a week early for cleaning and year-end parties. More critically, the return to full capacity is slow.

In the welding and heavy industry sectors, labor is physically demanding. Many migrant workers from rural provinces return home for Tet and decide not to return to the city, or they delay their return until weeks after the holiday concludes. It is common for a factory to operate at only 40% to 60% capacity for the first two to three weeks after reopening. This "post-Tet hangover" means that even if you place an order on the first day back, it will sit in a queue.

Calculating Your Q1 Safety Stock

To determine the correct buffer, you cannot use your standard lead time formulas. You must account for the "Blackout Period" where no output occurs, plus the "Recovery Period."

• Standard Lead Time: 45 Days
• Tet Blackout: +14 Days (Pre-holiday stop + Holiday)
• Recovery Lag: +14 Days (Slow ramp-up)
• Logistics Lag: +7 Days (Port congestion clearing)

If your typical reorder point is 100 units reorder point ⁹, you likely need to carry 135-150 units into January to remain safe.

We also suggest a strategy of diversification. If your volume allows, do not rely 100% on a single Vietnamese supplier for critical welding components during Q1. Having a backup supplier in a country with different holidays, such as Thailand or India, can save you from a stockout. However, if Vietnam is your sole source, you must pull forward your Q2 demand. We often help clients identify "fast-moving" versus "slow-moving" SKUs. For custom aluminum frames that are project-specific, we expedite the entire batch. For standard recurring parts, we ship a larger sea freight container in December and keep a small budget for emergency air freight in late February if demand spikes unexpectedly.

What logistics and shipping delays should I expect at Vietnamese ports leading up to major public holidays?

We constantly monitor trucking routes to Hai Phong as drivers leave early for their hometowns. Ignoring inland logistics bottlenecks often leads to missed vessel cut-offs.

Expect severe congestion at ports like Hai Phong and Cat Lai starting three weeks before the holiday. Trucking availability drops by 50% as drivers return home, so you should book ocean freight space six weeks out and move cargo to port warehouses early.

The logistics ecosystem in Vietnam is heavily reliant on trucking to move goods from industrial parks (like VSIP in Binh Duong or Bac Ninh) to the major ports. The trucking workforce is predominantly male and from the provinces, meaning they are the first demographic to exit the city for the holidays. Approximately two weeks before Tet, finding a container truck becomes a bidding war. Prices can surge by 30-50%, and confirmed bookings can be cancelled last minute if a driver simply decides to go home early.

At the ports, the situation is equally chaotic. Exporters are rushing to get goods on the water before the break, leading to massive queues at the terminal gates. Ports like Cat Lai in the south and Hai Phong in the north Катлай ¹⁰ operate with skeleton crews during the holiday, but the weeks prior are characterized by "rolled cargo." This happens when your container is delivered to the port, but the vessel is overbooked, and your box is left behind for the next sailing—which might not be for another week or two.

Logistics Bottleneck Checklist

To navigate this, we use a checklist to ensure our clients' goods make it on board.

Another factor to consider is the "Cut-Off" time. Usually, you might deliver cargo 24 hours before the vessel departs. During the pre-Tet season, terminals may close gates 48 or 72 hours early due to yard congestion. We always advise shipping via a "Split-Shipment" method if you are behind schedule. Send the absolute critical quantity (e.g., 10% of the order) via air freight or LCL (Less than Container Load) immediately, and let the bulk follow via sea freight. It is expensive, but cheaper than a line-down situation at your facility.
