Payment & Buyer Protection

Cross-border buying works on trust. Here is exactly how we handle orders, how you pay, and how to check that a payment request really came from us.

How an order runs, end to end

Nothing is charged until you have approved a written quotation. This is the same sequence we use for a first sample request and for a 100,000-piece production order.

  1. You build an inquiry list — add part numbers and quantities on the site, or paste your BOM. No account, no payment details, nothing charged.
  2. We quote in writing within 24 hours — unit price, MOQ, lead time, Incoterm, freight and the validity date of the offer, sent from ben.jiang@chuainet.com.
  3. You approve, we issue a Proforma Invoice (PI) — the PI carries a unique reference, our full company details and the payment route you chose.
  4. You pay — PayPal for smaller orders, bank transfer (T/T) for larger ones. We start production or picking only after the funds are visible on our side.
  5. We ship and send documents — DHL / FedEx / UPS tracking number, commercial invoice, packing list, and Certificate of Origin on request.
  6. After-sales — 30-day quality window with replacement or refund for confirmed defects.

Two ways to pay

Pick the one that matches your order size. We do not accept Western Union, cryptocurrency or gift cards.

PayPal Best for small orders

Fast, and it keeps your card details away from us entirely — you pay inside PayPal, we never see your card number.

  • Good for: samples, evaluation batches, orders roughly USD 50 – 3,000
  • You pay to: ben.jiang@chuainet.com (verified business account)
  • Currencies: USD, EUR, GBP and more
  • Protection: PayPal Buyer Protection applies to eligible purchases
  • Speed: funds confirmed within minutes — we dispatch sooner

A PayPal fee is added by PayPal to the transaction; it is shown on the invoice before you pay, so the amount you approve is the amount you pay.

Bank transfer (T/T) Best for larger orders

The standard route for B2B semiconductor purchasing. No percentage fee, so it becomes much cheaper than card payments as the order grows.

  • Good for: production volumes, from about USD 3,000 upwards
  • Beneficiary name: Shanghai Chuai Network Technology Co., Ltd.
  • Terms: 100% before shipment, or 30% deposit + 70% before shipment for larger builds
  • Documents: Proforma Invoice for the deposit, Commercial Invoice for the balance
  • Speed: typically 1–3 business days to clear

Your bank and any intermediary banks may charge their own fees — please instruct your bank that all charges are for the remitter’s account so the full invoice value arrives.

Why we do not publish our bank account on this website. Published account numbers are copied by fraudsters and reused on fake invoices. We only issue bank details inside a numbered Proforma Invoice sent from ben.jiang@chuainet.com, and every invoice can be verified on our Track & Verify page before you send money.

How to be sure a payment request is genuine

Payment-redirection fraud is the single most common way cross-border buyers lose money. Four checks take under a minute and remove the risk entirely.

Stop and verify if any of these are true

  • The email asks you to pay a personal bank account or any name other than Shanghai Chuai Network Technology Co., Ltd.
  • The bank details arrived in a second email, or an email claiming our details “have changed”.
  • The sender domain is not exactly chuainet.com — watch for look-alikes such as chuainet-cn.com, chuainet.net, or a free mailbox such as gmail / 163 / qq.
  • Someone asks for Western Union, cryptocurrency, gift cards, or a payment to a “clearing agent”.
  • Anyone asks for your card number, CVV, online-banking password or SMS code — we never need these.
  • You are pressured to pay within hours to “hold the allocation”, or told the price is only valid for a few minutes.
  • A message on any chat app arrives from a number you have never spoken to, carrying payment instructions.

Four checks that confirm it is really us

  • Verify the reference. Paste the reference number from your Proforma Invoice into Track & Verify. A genuine document returns the matching company, part list and amount.
  • Check the sender domain. Legitimate mail comes from @chuainet.com only. Reply to that address rather than to a forwarded message.
  • Match the beneficiary name exactly. It must read Shanghai Chuai Network Technology Co., Ltd. in full — a mismatch of even one word means stop.
  • Write back to the address published on this site. Type ben.jiang@chuainet.com by hand — never hit reply on a forwarded message — and ask us to confirm the reference and the beneficiary name. Any genuine reply comes from @chuainet.com only.
✓ One official domain: chuainet.com ✓ One official mailbox: ben.jiang@chuainet.com ✓ Verifiable invoice references ✓ No personal accounts, ever

What protects your money after you pay

Before dispatch

  • Lot / date code recorded on every shipment
  • Packaging photographs sent on request
  • Anti-static (ESD) packaging and moisture-barrier bags
  • Commercial invoice and packing list with every parcel
  • Certificate of Origin on request

After receipt

  • 30-day quality window from delivery
  • Confirmed defects: replacement or refund
  • Return freight on defective material covered by us
  • Technical support on integration and firmware
  • Cross-reference help if a part is discontinued

Documentation you can request

  • Proforma Invoice (before payment)
  • Commercial Invoice + Packing List (with goods)
  • Certificate of Origin (CO / Form A / FTA as applicable)
  • RoHS / REACH declarations
  • AEC-Q100 qualification evidence for automotive lines

Compliance

We export in line with Chinese export-control and customs regulations. Depending on the part and destination we may ask you to confirm the end user and end use in writing before shipping — this is a legal requirement for both sides, and it protects legitimate buyers from being caught up in diversion issues.

Common questions

Do I have to pay before I get a quotation?

No. Submitting an inquiry list costs nothing and commits you to nothing. You receive a written quotation first, and payment is only requested after you approve it.

Which payment method should I choose?

PayPal is the quickest route for small orders (roughly USD 50–3,000) and gives you PayPal Buyer Protection. Bank transfer (T/T) is cheaper for larger orders because there is no percentage fee — we recommend it from about USD 3,000 upwards. Tell us your preference in the inquiry and we will follow it.

How do I know a payment request is really from you?

Every Proforma Invoice carries a reference number that can be verified on our Track & Verify page. Payment requests only ever come from ben.jiang@chuainet.com, and the beneficiary name must always be exactly “Shanghai Chuai Network Technology Co., Ltd.” — never a personal name, never a third party.

What if the parts are faulty?

Contact us within 30 days of receipt with photos and the test data. Confirmed quality issues are replaced or refunded, and we cover the return freight for defective material. Parts that fail our own pre-shipment check are never shipped in the first place.

Are the parts original and traceable?

We supply through authorised distribution channels. On request we provide the lot / date code, packaging photos before dispatch, and a Certificate of Origin. Counterfeit risk is the reason we keep traceability documentation on every shipment.

Who pays duties and import taxes?

Unless your quotation says DDP, duties, VAT/GST and customs clearance at destination are the buyer’s responsibility. We always declare the true commercial value and ship with a commercial invoice and packing list, so there are no surprises at customs.
