Planning 1688 imports for the next Shopee or TikTok Shop sale season looks simple on paper until you do the math on lead times and realize you needed to place that order two months ago.
This post gives you a specific ordering calendar backed by real lead time data: air freight, surface freight, and the hidden delays that hit during peak sourcing season on 1688. If you run a shop on Shopee Vietnam or TikTok Shop and import regularly from 1688, this is the planning reference you want open when mapping out your Q3 and Q4 sourcing schedule.
Why Planning 1688 Imports for Sale Seasons Takes Longer Than You Think
Most shop owners underestimate total lead time by two to three weeks because they count only the international shipping leg.
Here are the actual numbers. From the moment you click "place order" on 1688 to the moment goods clear into your Vietnam warehouse, four legs add up:
- Supplier processing at 1688: 1 to 3 working days. Small suppliers and home-based sellers often run longer, especially for assembled or customized goods.
- Domestic China transit to border or air hub: 2 to 5 days. If your supplier is inland (say, Zhengzhou rather than Shenzhen), add another day.
- International transit: 3 to 7 days by air, 10 to 20 days by road or sea.
- Vietnam customs clearance and final delivery: 1 to 3 days under normal conditions.
Total: 15 to 20 days by air, 25 to 40 days by surface. Those figures assume normal operating conditions.
Now factor in what happens in the month before a major sale. Suppliers on 1688 are processing five to ten times their usual order volume. Processing time stretches by an extra 2 to 5 days, particularly for smaller sellers without dedicated warehouse staff. You see this clearly when you compare order timelines in August versus October versus a quiet February.
The business cost of getting this wrong is not temporary. When a flash sale SKU runs out mid-event, the platform algorithm logs a fulfillment failure. Both Shopee and TikTok Shop penalize shops that can't fill demand during peak windows, pushing competitors with available stock higher in search and recommendation feeds. That ranking hit outlasts the sale itself.
And if you're placing a last-minute order to cover a gap, you're locked into air freight. Depending on category and forwarder, that's 30 to 50 percent more per kilogram compared to booking surface freight six to eight weeks in advance.
Shopee and TikTok Shop Sale Calendar: Dates to Lock Into Your Plan
Nine major sale events run across the year: 3.3, 6.6, 7.7, 8.8, 9.9, 10.10, 11.11, 12.12, and Tet. Most operators know these dates. What matters for sourcing is deciding which ones to fully stock for, based on your category and available working capital.
One date that operators consistently miss: pre-sale opens 5 to 7 days before the headline sale date. Your goods need to be in your warehouse before the pre-sale window, not before the sale date itself. Pre-sale is where flash deal listings, bundles, and early voucher redemptions happen. Stock arriving on November 11 means you missed the pre-sale revenue entirely.
TikTok Shop adds a layer of complexity. Mega monthly sales are scheduled, but individual live flash sales are unannounced. If you're running live commerce on TikTok Shop, you need a baseline buffer stock that covers unplanned volume spikes throughout the month, not just the fixed sale calendar.
On relative sale weight: 11.11 is the highest-GMV event of the year. Plan your largest stock position and your largest ad budget here. 9.9 plays a different role. Experienced operators use 9.9 as a live test for new SKUs. The volume is lower, the downside is limited, and you get real conversion data to size your 11.11 order accurately. Import conservatively for 9.9, then use that data hard.
Lead Times Importing from 1688 to Vietnam: Breaking Down Each Leg
Each leg has variance, and that variance compounds across the full chain.
Leg 1: Supplier processing (1 to 3 working days). The time between payment confirmation and handoff to a freight forwarder or domestic carrier. Suppliers with integrated warehouse operations run closer to one day. Weekend orders and custom items stretch this.
Leg 2: China domestic transit (2 to 5 days). Goods travel from the supplier's location to a consolidation warehouse, air hub, or border crossing. Major freight hubs (Guangzhou, Shenzhen, Yiwu) move faster. Inland cities add a day or two.
Leg 3: International transit. Air: 3 to 7 days. Road through Lao Cai or Huu Nghi: 7 to 14 days. Sea: 12 to 20 days depending on routing and port congestion.
Leg 4: Vietnam customs and delivery (1 to 3 days). Accurately declared commercial shipments under standard value thresholds clear fastest. Flagged or underdeclared shipments can sit 5 to 10 days. Consistent, accurate declaration builds a cleaner clearance history over time.
On method selection: items under approximately 3 kg per unit can move viably by air. Above that threshold, air freight costs scale quickly. Heavy or bulky categories (furniture, appliances, large home goods) are almost exclusively surface freight, which means your planning window needs to be 8 to 10 weeks minimum.
Add 3 to 5 days of buffer during the four weeks before any major sale. Customs at Lao Cai and Noi Bai both see volume spikes during peak import periods. Build that buffer into your calculation, not just your contingency thinking.

Countdown Framework: Working Back from Sale Day to Order Date
The core formula:
Order date = Sale date - shipping lead time - 7-day safety buffer - 2 to 3 days for QC and labeling at your Vietnam warehouse
Applied to the three largest sale events:
9.9 (September 9)
Method | Order by |
|---|---|
Air freight | August 5 to 10 |
Surface (road/sea) | July 25 to August 1 |
11.11 (November 11)
Method | Order by |
|---|---|
Air freight | October 5 to 12 |
Surface (road/sea) | September 25 to October 1 |
12.12 (December 12)
Method | Order by |
|---|---|
Air freight | November 5 to 12 |
Surface (road/sea) | October 25 to November 1 |
These dates account for normal lead time plus peak-season buffer. They do not account for one common scenario: you're sourcing a new product and haven't confirmed quality yet.
If you're working with a new supplier or a new SKU, add 7 to 14 days for sampling. Order the sample separately, inspect it, then place the bulk order. This sequence is not optional if you're importing more than a few hundred units. Do not absorb sampling time into your main order lead time. If the sample fails, your timeline collapses.
Concrete example: a fashion accessories shop preparing for 11.11, new 1688 supplier. Working backward:
- November 11: sale day
- November 8: pre-sale opens (goods must be warehouse-ready)
- November 5: latest in-warehouse arrival, including QC and labeling time
- October 29: departure from China (air)
- October 26: goods at forwarder in China
- October 24: order placed with supplier
That's October 24 as the order date, assuming sample is already confirmed. If sample confirmation is still pending on October 10, you have two weeks to receive, review, and approve before committing volume. Miss that window and you're either importing untested product or skipping 11.11 on that SKU.
Inventory Planning: How Much to Import for a Sale Season?
The starting point is last year's data. Pull your GMV for the same sale event, check your sell-through rate, and use that as the baseline. If you ran at 80 percent sell-through, you likely under-stocked. If inventory was still sitting in late December, you over-bought.
Without prior data, the working estimate is: average monthly GMV multiplied by an uplift factor. For Shopee Vietnam, typical GMV uplift during major sales runs 2 to 4 times normal monthly revenue, depending on category, ad spend, and voucher depth. Use 2x as a conservative floor for your first sale season, then recalibrate with actual data.
Carry 20 to 30 percent above your baseline forecast as safety stock. Sales spike unevenly across SKUs. Some items outperform forecast by 3x while others barely move. The buffer protects your top performers. For a framework on calculating the right stock level without over-investing working capital, read how to calculate inventory turnover for 1688 imports.
Apply ABC classification to your SKU list before committing orders:
- Group A (bestsellers, proven conversion history): Buy to full forecast, carry the safety stock buffer.
- Group B (consistent but not top performers): Buy to forecast, smaller buffer.
- Group C (new, experimental, or slow-moving): Buy minimally before a sale. Do not front-load capital into unproven SKUs when cash needs to back your A-tier stock.
Before locking any quantity, calculate your actual landed cost per unit. The 1688 price is one input. Freight, forwarder service fees, import duties, and warehouse handling all stack on top. An item listed at 50,000 VND on 1688 can arrive at 85,000 to 100,000 VND all-in. That changes the math on how aggressively you can discount during flash deals. Get this calculation right before committing volume. The full breakdown is in how to calculate true cost of goods from 1688.
Six Mistakes Operators Make When Stocking 1688 Goods for Peak Season
1. Skipping the sample on large orders. Placing a 500-unit order without testing a sample first is how you end up with a warehouse full of defective goods the week before a sale. There is no recovery play for that. Require a sample on every new supplier and every new SKU, regardless of how tight the timeline looks.
2. Calculating landed cost from the 1688 price alone. Shipping, forwarder fees, and import duties routinely add 30 to 60 percent on top of sourcing price. Operators who miss this set sale prices too low, run flash deals at near-zero margin, and don't find out until month-end reconciliation. See full cost breakdown for 1688 imports to build a proper landed-cost model before your next order.
3. Consolidating all SKUs into a single shipment to save on freight. This makes sense for costs in isolation. It fails in practice because one delay, one customs hold, or one inspection flag takes down your entire pre-sale inventory simultaneously. Split shipments by SKU group, especially for A-tier products.
4. Ignoring QC and labeling time at your Vietnam warehouse. Receiving goods and having them shelf-ready are two different events. Counting, inspecting, barcoding, and repackaging a 300-unit shipment takes 2 to 5 days depending on your setup. Build this into the deadline. "Goods arrive November 8" does not mean "goods are live on November 8."
5. No backup supplier. Your primary 1688 source goes out of stock or misses the production deadline. Without a second option already identified, you enter the sale empty-handed on that SKU. Keep at least one alternative supplier noted for each A-tier product. You don't need to order from them regularly. You just need to know they exist and can deliver.
6. Paying in full before quality inspection. Full upfront payment before goods are inspected gives you no leverage when a shipment arrives wrong-spec or damaged. Use a payment structure that holds back a portion until quality is confirmed. The inspection process is covered in detail at how to inspect 1688 goods before paying.
FAQ: Planning 1688 Imports Before a Sale Season
How far in advance should I order from 1688 before a sale?
Minimum 6 to 8 weeks before goods need to be in your warehouse for air freight, and 8 to 10 weeks for surface. Count backward from your warehouse arrival date, not from the sale date. Pre-sale windows add another 5 to 7 days to the requirement on top of that.
How does inventory planning for 9.9 differ from 11.11 and 12.12?
11.11 is the peak event. Expect to stock 2 to 3 times what you'd carry for 9.9. 12.12 typically runs lower than 11.11. Many operators cover 12.12 using leftover 11.11 inventory on stable SKUs rather than placing entirely new orders. For 9.9, import conservatively and treat it as a data run for your 11.11 sizing.
Can I use sea freight to reduce costs before 11.11?
Yes, if you order at least 10 weeks out and can absorb the delay risk. Sea freight is the right call for large quantities of high-volume, stable SKUs where the cost savings justify the lead time. A practical hybrid: sea freight for core stock, air freight for a smaller top-up order if you're running low after 11.11 pre-sale opens.
How do I estimate order quantity for a first-time sale on Shopee or TikTok Shop?
Multiply your current average monthly revenue by 2 to 3 for a first sale event. Import that quantity, track sell-through carefully, then use the actual numbers to model the next event. First-sale estimates are inherently rough. The goal is not running out on your top SKUs while not over-committing capital to unproven ones.
What do I do if my 1688 supplier says they're out of stock close to the sale?
Search immediately for a secondary supplier using the same product keywords on 1688. If you can't get delivery in time, shift your ad budget toward SKUs that are fully stocked. Do not continue promoting a depleted SKU. It wastes ad spend and creates negative customer experience if orders slip into backorder.
If you want to apply this kind of timeline planning systematically across your full SKU catalog, that's part of what we're building at Ordinex. The Scout tool (currently in private beta) surfaces supplier lead time signals and helps map order windows to your sale calendar. The Orders module tracks per-shipment status so you can see exactly which leg each batch is on and whether it's on pace to arrive before pre-sale opens. If that's useful for how you run your shop, follow updates or join the waitlist at ordinex.cc.
