Some of the most expensive lessons in importing come from basic, avoidable mistakes. Not bad products — but overlooked details that turn a profitable order into an expensive headache.
Here are five mistakes that cost US importers real money, and how to make sure they don't happen to you.
Mistake 1: Looking Only at Price, Ignoring Certifications
It's the most natural thing in the world: you find a product on 1688 for $3.50, do quick math on your margins, and place an order for 500 units.
Then your shipment arrives at US customs — and gets held. The reason? Your product doesn't have the required FCC certification for electronics, or UL certification for appliances.
A common scenario: An importer brings in a container of electronic gadgets from a new 1688 supplier. The products arrive at US customs and get flagged because none have FCC certification. The shipment gets held, storage fees pile up, and they end up paying thousands to get it released or shipped back.
What to check before you order
| Certification | Required For | Cost If Missing |
|---|---|---|
| FCC | Electronics, wireless devices | Shipment seized, fines up to $100k |
| UL / ETL | Appliances, electrical products | Retailers won't stock |
| FDA | Food contact, cosmetics, medical | Legal liability, forced recall |
| CPC | Children's products | Amazon suspension, penalties |
Ask your supplier upfront: "Do you have [FCC/UL/FDA] certification for this product? Can you send me the certificate number so I can verify it?"
If they don't know what you're talking about, that's a red flag. Legitimate factories that export regularly will have certification documentation ready.
Mistake 2: Trusting a Middleman Who Says They're a Factory
On 1688 and Alibaba, many sellers list themselves as "factories" when they're actually trading companies. Nothing wrong with trading companies — but you should know who you're dealing with and pay accordingly.
The difference matters:
- Real factory: You pay factory-direct price, get direct quality control, and build a long-term relationship
- Trading company: You pay a 15-30% markup, have limited quality control, and don't know the actual source
How to spot a trading company
Check their business license (营业执照) — A factory's license will list manufacturing as its primary business scope. A trading company lists "wholesale" or "retail."
Ask for a video walkthrough — A real factory will show you production lines, raw material storage, and finished goods areas. A trading company will give excuses or show you a small office.
Look at their product range — If they sell 500 completely unrelated products (massage guns, kitchen knives, baby clothes), they're almost certainly a trading company. Factories specialize.
Use reverse image search — Upload their product photos to 1688 image search. If multiple sellers use the same photos, you're looking at a trading company's catalog.
A rule of thumb: If you're buying from a trading company, expect to pay 15-30% more than factory price. That's fine if the trading company provides value (quality checks, consolidated shipping). Just know what you're paying for.
Mistake 3: Negotiating Only Price, Forgetting Payment Terms
Many new importers focus all their energy on getting the lowest unit price — then get burned on payment terms.
Here's what can go wrong:
- You pay 100% upfront (common with new relationships), and the supplier ships late or sends low-quality goods
- You only discussed USD pricing, then currency fluctuations eat your margin during production
- The supplier demands a different payment method at the last minute, and you're stuck
Recommended payment structure
For first orders with a new supplier:
- 30% deposit when you place the order
- 70% balance before shipment, after you've approved photos/video of the finished goods
This protects both sides. The supplier has enough to cover materials, and you have leverage to ensure quality.
Payment method safety ranking:
| Method | Buyer Protection | Typical Fee |
|---|---|---|
| Alibaba Trade Assurance | High — Alibaba holds funds | 0-2% |
| PayPal Goods & Services | High — dispute resolution | 4-5% |
| T/T (Wire Transfer) | Low — hard to recover | 0.1-0.5% |
| Western Union | Very low — not recommended | Varies |
Mistake 4: Forgetting About Chinese Holidays
You place an order on January 15 and expect delivery in 3 weeks. But Chinese New Year starts next week, and factories shut down for 20+ days. Your order doesn't ship until March.
This happens every year, yet it catches importers by surprise every time.
2026 Chinese holiday calendar
| Holiday | 2026 Dates | Impact |
|---|---|---|
| Chinese New Year (Spring Festival) | Feb 17 — Mar 5 | Factories shut 2-3 weeks, everything stops |
| Qingming Festival | Apr 4 — Apr 6 | 3 days, minor impact |
| Labor Day | May 1 — May 5 | 5 days, some factories close |
| Dragon Boat Festival | Jun 19 — Jun 21 | 3 days, minor impact |
| Mid-Autumn Festival | Sep 27 — Sep 28 | 2 days, minor impact |
| National Day (Golden Week) | Oct 1 — Oct 7 | 7 days, many factories close |
How to plan around holidays
- Chinese New Year: Place orders before December, or accept that anything ordered after early January won't ship until March
- National Day (Oct 1-7): Plan inventory so you don't need orders during this window
- General rule: Add 2 weeks to any lead time that overlaps with a major holiday
Pro tip: Ask your supplier "Will your factory be open during [holiday]?" before you place an order. Honest suppliers will tell you straight. If they say "no problem" and then go silent for two weeks, you know what you're dealing with.
Mistake 5: Underestimating Hidden Logistics Costs
The product costs $4.00 on 1688. You plan to sell it for $19.99 on Amazon. The math looks great — until you factor in everything else.
The real cost breakdown for a typical import shipment:
| Cost Item | Amount | Notes |
|---|---|---|
| Product cost (500 units × $4) | $2,000 | The obvious cost |
| Domestic shipping to warehouse | $80 | China domestic freight |
| Sourcing agent fee (5%) | $100 | If using an agent |
| International sea freight | $350 | 1 CBM, port to port |
| Customs brokerage & duties | $120 | ~5-8% of value |
| US port handling & local delivery | $150 | Truck to your door |
| Total landed cost | $2,800 | $5.60 per unit — 40% more than product cost alone |
Most beginners only calculate the product cost. The real number is always higher.
How to estimate your true costs
Use this simple formula:
Landed Cost = Product Price × 1.4 (rough estimate)
+ Shipping per Unit
+ Duty per Unit
+ Agent Fee (if applicable)
For a more accurate picture, ask your supplier or freight forwarder for a full "DDP" (Delivered Duty Paid) quote. This gives you the all-in cost delivered to your door.
The Checklist: Before You Place Your Next Order
Print this and run through it before every order:
- Does this product require certifications (FCC, UL, FDA, CPC)?
- Have I verified the supplier's business license?
- Is the supplier a factory or a trading company?
- Have I negotiated payment terms I'm comfortable with (30/70 split)?
- Are there any Chinese holidays in the next 6-8 weeks?
- Have I calculated total landed cost, not just product cost?
