Getting the 1688 import cost breakdown right before your first shipment is the difference between a profitable SKU and one that wipes its margin before it clears customs. Most operators starting out see the factory price, run a quick exchange rate conversion, and treat that as their cost. By the time the goods land, the actual cost per unit is 35-55% higher.
The reason is not complexity. The true cost sits across seven separate layers, and most sourcing guides only cover one or two. This post walks through all seven, with a worked example using 200 garments shipped from Guangzhou to Hanoi so you can run the same calculation on your own SKUs.
Why new operators consistently get their 1688 cost wrong
The 1688 platform surfaces one number prominently: the listed unit price in quantity tiers. Everything downstream is the operator's problem to figure out. Three specific gaps trip new operators up, over and over.
Domestic China freight. Moving goods from a factory in Foshan or Shantou to a consolidation warehouse is a real cost: 3-12 CNY per kg depending on province and carrier. For a 200-piece apparel order at 1.5 kg per piece average, that is 300 kg of domestic freight before anything crosses a border.
The exchange rate gap. Most operators check the mid-market CNY/VND rate on a banking app and use that to build their cost model. The problem is that 1688 Pay, Alipay, and most sourcing agent payment services apply their own rate running 2-4% above mid-market. On a 15,000 CNY order, that gap is 300,000-600,000 VND that disappears silently.
Import duty. A lot of new operators assume goods will clear under informal thresholds or apply a blanket 10% estimate. Vietnam's tariff schedule uses HS-code-specific rates from 0% to 30%, with 10% VAT added on the dutiable value. Estimating the wrong rate by 5 percentage points can flip a profitable SKU into a loss.
The result is predictable: you price based on a cost model that is 15-25 margin points too optimistic, and you either sell below true cost or reprice above what the market accepts.
The seven-layer structure below gives you a consistent framework for every order.
The 1688 import cost breakdown: 7 fee layers
Layer 1: Listed price on 1688
Factory gate price per unit, shown in tiered quantities. Read the tiers carefully. A supplier quoting 52 CNY at 200+ pieces may quote 68 CNY for 50 pieces. That 31% difference changes your whole cost stack. Always use the price for the tier you will actually order at, not the tier you hope to reach.
Layer 2: Domestic China freight
Factory to consolidation warehouse, priced per kg. Typical range: 3-12 CNY/kg depending on origin province and service type. Guangdong factories are cheapest. Zhejiang or Jiangsu factories add distance and cost. For a 300 kg order, budget 900-3,600 CNY before anything moves internationally.
Layer 3: Consolidation warehouse fees
If you order from multiple suppliers in one shipment (standard practice when testing several SKUs), each parcel arrives at a warehouse to be counted, inspected, repacked, and consolidated into one outbound box. Typical fee: 3-8 CNY per kg, or a flat 30-80 CNY per supplier parcel. Optional add-ons include quality photography and custom labeling.
Layer 4: International freight
Sea (LCL): priced by CBM. A 200-piece t-shirt order occupies roughly 0.3-0.5 CBM. South China to Hanoi via LCL runs USD 130-180 per CBM plus fixed handling. Total for a small apparel order: USD 50-90.
Air freight: priced by actual weight or volumetric weight (L x W x H in cm / 5,000), whichever is higher. Guangzhou to Hanoi runs USD 4-8 per kg. For the same 300 kg sea shipment, air would cost USD 1,200-2,400. The break-even: if you do not need the goods within 5-7 days and the shipment weighs over 10 kg, sea beats air on cost by a wide margin.
For a full comparison on choosing between modes, see the guide on shipping goods from China to Vietnam.
Layer 5: Import duty and VAT
Vietnam calculates duty on the CIF value (cost, insurance, freight) using HS-code-specific rates. For garments under HS 6109 (knit t-shirts, polos), the standard rate is 10-12%. After duty, 10% VAT is applied on the sum of CIF plus duty.
On a CIF value of USD 1,500 at 10% duty: duty = USD 150, VAT = (1,500 + 150) x 10% = USD 165, total tax = USD 315. That is 21% of CIF sitting on top of every other cost. Always look up the actual HS code for your product before the first order. For a breakdown by product category, see the article on import duty for Chinese goods entering Vietnam.
Layer 6: Customs clearance and port fees
Broker fee, customs declaration, terminal handling charge, document handling, warehouse release. For a small LCL shipment into Hanoi or Ho Chi Minh City, expect USD 70-120 as an all-in flat charge. This is a fixed cost, so it dilutes harder on small orders: USD 90 spread over 20 units is USD 4.50 per piece; over 200 units it is USD 0.45 per piece.
Layer 7: Exchange rate margin
When you pay through 1688 Pay, Alipay, or a sourcing agent's payment account, the applied CNY/VND rate sits above mid-market, typically by 2-4%. On a 10,000 CNY purchase at 3% above mid-market, that is 1,050,000 VND per order that is invisible in a standard cost model. Across 20 orders a month, it becomes a real line item.
The formula for calculating your true 1688 landed cost
Landed cost per unit = [(Purchase CNY x Actual gateway rate) + Domestic China freight + Consolidation fees + International freight + Import duty + VAT + Customs clearance fees] / Units ordered
Apply it with these adjustments:
Use the actual rate applied by your payment gateway on the day you pay, not the mid-market rate. Add a 2% buffer on top of that rate to cover movement during the shipping window.
As a rough proportion benchmark for garments and accessories: the purchase price accounts for 55-65% of landed cost, freight and fees account for 25-35%, and tax accounts for 5-15% depending on the HS code.
Add a 5-10% risk buffer if you are placing a first order with a new supplier, sourcing products that are hard to inspect remotely, or shipping during peak seasons when freight rates spike sharply.
For what to do with the landed cost once you have it, see the article on calculating margin when selling 1688 products.
Worked example: 200 garments from 1688, Guangzhou to Hanoi
Setup: T-shirt listed at 52 CNY/piece, 200 units minimum, shipped LCL sea freight from Guangzhou to Hanoi. Mid-market rate: 3,500 VND/CNY. Gateway rate on payment day: 3,605 VND/CNY (3% above mid-market). USD/VND rate: 25,500.
Layer | Item | Total VND | Per unit |
|---|---|---|---|
1 | Purchase: 200 x 52 CNY x mid-market 3,500 | 36,400,000 | 182,000 |
2 | Domestic freight: 300 kg x 4 CNY x 3,500 | 4,200,000 | 21,000 |
3 | Consolidation: 300 CNY flat x 3,500 | 1,050,000 | 5,250 |
4 | LCL freight: 0.4 CBM x USD 150 x 25,500 | 1,530,000 | 7,650 |
5 | Duty + VAT (HS 6109, 10% duty on CIF ~USD 1,502) | 8,030,000 | 40,150 |
6 | Customs + port: USD 95 flat x 25,500 | 2,422,500 | 12,113 |
7 | FX spread 3% on CNY layers: 41,650,000 x 0.03 | 1,249,500 | 6,248 |
Total | 54,882,000 | ~274,000 |
Mid-market spot value: 182,000 VND/piece. Actual landed cost: ~274,000 VND/piece. Gap: 51% above the naive spot conversion.
The practical rule for basic knit garments shipped LCL from South China: take the 1688 listing price, convert at mid-market, then add 50-55% to approximate landed cost. That ratio decreases for higher-value items (fixed fees shrink as a share) and increases for very small orders (fixed costs spread over fewer units).
Hidden fees that get missed and how to buffer for them
Even with all seven layers in your model, four costs surface regularly enough to plan for.
Customs inspection fees. Around 10-20% of first-time importer shipments get pulled for physical inspection. When that happens, you pay port storage during the delay (typically 50,000-150,000 VND per day per CBM) plus any recount or repack fees. Not common, but not rare either.
Port demurrage and detention. If customs documentation is incomplete or the shipment is held, daily storage charges at Vietnamese ports accumulate fast. Complete paperwork eliminates most of this risk, but missing a single document on a Friday afternoon can cost 2-3 days of fees before anyone processes the release.
Cumulative exchange rate drift. Each individual 2-4% FX spread looks manageable. Run 15-20 orders a month and you are looking at 300,000-1,200,000 VND per order leaking invisibly from your margin. Aggregate it annually and it is a meaningful cost center that most operators have never accounted for explicitly.
Defect and claims buffer. For garments, plan for 2-3% of units being unusable due to defects, wrong sizes, or quality issues. For small electronics, budget 3-5%. This is not a fee, but it is a real reduction in sellable units that raises your effective per-unit cost.
Tracking costs per SKU to avoid hidden losses
The most common error after learning the formula is applying it to the whole shipment rather than per product code.
Import three SKUs in one order: a cotton tee at 52 CNY and 1.5 kg/piece, a synthetic jacket at 88 CNY and 0.3 kg/piece, and a canvas tote at 15 CNY and 0.4 kg/piece. The freight cost per kg is identical for all three, but the ratio of freight cost to purchase price is completely different across them. Blending the cost across the order means you under-cost the heavy item and over-cost the light one. You will not know which SKU is actually profitable until you separate the math.
The minimum viable cost sheet: one row per product code, seven cost columns, updated after each shipment. If actual margin runs more than 10 percentage points below the estimate across two consecutive orders, one of the seven layers has changed or there is an untracked cost being absorbed silently. For more on diagnosing these gaps over time, see the article on hidden costs when importing from 1688.
FAQ: common questions about 1688 import costs
Which CNY/VND exchange rate should I use for cost calculations?
Use the rate your payment gateway applies on the day you actually transfer funds, not the mid-market rate from a banking app. 1688 Pay, Alipay, and most sourcing agent payment accounts run 2-4% above mid-market. Add an additional 2% buffer on top of the gateway rate to cover rate movement during the shipping window. Using mid-market as your baseline for a shipment that takes 15 days can easily produce a 5-6% rate variance that quietly eats into your margin.
How is import duty calculated for 1688 goods entering Vietnam?
Duty is based on the CIF value of the shipment (cost plus insurance plus freight), at the HS-code-specific tariff rate for your product category. Rates range from 0% to 30% depending on the product. Vietnam then applies 10% VAT on the sum of CIF plus duty. Look up the HS code for your product at customs.gov.vn before placing your first order. A generic 10% estimate will be wrong for most product categories.
Sea freight or air freight from 1688: which is cheaper and how do I choose?
Sea freight runs 60-80% cheaper per kg than air but takes 10-20 days from South China to Vietnam. Air makes sense for high-value, low-weight products where the cost per kg of the goods is above roughly USD 70, or for urgent restocks where a stockout costs more than the freight premium. The practical break-even: if your shipment weighs more than 10 kg and you have 2-3 weeks of inventory buffer, LCL sea is the better choice almost every time.
Is importing fewer than 50 units from 1688 cost-viable?
It works, but fixed costs (consolidation fees, customs clearance minimums, LCL freight handling charges) do not scale down with unit count. A USD 90 clearance fee spread over 20 units adds USD 4.50 per piece. Spread over 200 units it is USD 0.45. Two approaches help: consolidate several small test SKUs into one shipment to share the fixed cost, or treat the per-unit premium on small first orders as product validation spending rather than optimized buying.
Is there a tool that automatically calculates 1688 import costs?
Most operators currently track this in a manually maintained spreadsheet, updating exchange rates by hand and recalculating each time freight rates or customs fees change. Ordinex Scout (currently in private beta) handles landed cost calculation per SKU with live exchange rates, so you see the real cost at the point of sourcing rather than after the shipment arrives. If you want early access, the waitlist is open at ordinex.cc.
