The Hidden Cost of Trading Companies
Most first-time vacuum bag importers start with a trading company — and leave 40-60% of their potential margin on the table. Trading companies don’t manufacture; they source from factories, add a markup (typically 15-30%), and resell. For a 40-foot container of vacuum compression bags worth $25,000 at factory price, the trading company markup alone can exceed $5,000-$7,500 per shipment.

Beyond the direct markup, trading companies introduce additional costs: communication delays (every question goes through a middleman), quality inconsistencies (they may switch factories between orders), and limited customization options (no direct access to the production line). This article breaks down the real numbers and shows how direct factory sourcing transforms your unit economics.
Cost Breakdown: Trading Company vs. Direct Factory
| Cost Element | Via Trading Co. | Direct Factory | Savings |
|---|---|---|---|
| Unit cost (Standard PA+PE bag, 60x80cm) | $0.22-0.28 | $0.12-0.18 | 30-45% |
| Custom packaging (header card) | $0.08-0.12/unit | $0.03-0.05/unit | 55-62% |
| Private label MOQ | 10,000+ pcs | 1,000-3,000 pcs | Lower barrier |
| Quality control | Variable (factory may change) | Consistent (direct relationship) | Lower return rate |
| Lead time visibility | Opaque | Transparent | Better planning |

Via Trading Company
- Unit cost: $0.25 × 20,000 = $5,000
- Packaging (included in trading co. price): $0
- Ocean freight (5 CBM shared container): $600
- Customs/duties (assume 6.5%): $364
- Total landed cost: $5,964
- Landed cost per unit: $0.30
Via Direct Factory (Qingdao Sanyuan)
- Unit cost: $0.15 × 20,000 = $3,000
- Custom packaging: $0.04 × 20,000 = $800
- Ocean freight (5 CBM): $600
- Customs/duties (6.5% on $3,800): $247
- Total landed cost: $4,647
- Landed cost per unit: $0.23
The Bottom Line
Savings: $1,317 per 20,000-unit order — a 22% reduction in landed cost.
Over 6 shipments per year: $7,902 annual savings.

If you retail these bags at $1.99 each on Amazon (after FBA fees of ~$1.30/unit, netting ~$0.69/unit), the $0.07/unit cost savings adds $1,400 in additional annual profit per 20,000 units sold — just from switching to direct sourcing.
Shipping Math: Optimizing Freight Costs
Vacuum compression bags are lightweight but bulky. Here’s how to optimize your shipping:

- Compression ratio matters: Vacuum bags can be compressed to 25-30% of their unpacked volume during shipping. Request vacuum-sealed master packs from your factory — this can reduce freight volume by 40-60%.
- HS Code 3923.21: Articles for the conveyance or packing of goods, of plastics — sacks and bags of polymers of ethylene. Duty rates: EU 6.5%, USA 3.0% (2024 rates).
- FCL vs. LCL breakpoint: For orders above ~15 CBM, a 20-foot container (FCL) is cheaper than shared-container (LCL). For vacuum bags, ~100,000-150,000 units fill a 20-foot container.
- DDP vs. FOB: For Amazon FBA sellers, DDP (Delivered Duty Paid) eliminates customs surprises. Expect a 10-15% premium over FOB for the convenience.
5 Signs You’re Ready for Direct Factory Sourcing
- You’re ordering 5,000+ units per shipment — this volume justifies the upfront work of supplier qualification
- You have a stable product specification — constant spec changes are difficult with direct factory relationships
- You want private label or custom packaging — trading companies charge a significant premium for customization
- Your current defect rate exceeds 3% — direct factory QC typically achieves <1%
- You’re planning to scale to multiple product lines — a factory partner can co-develop new SKUs
