07. Non-Transparent Exchange Rate & Tax

Overview

A supplier quotes a price without saying whether it's tax-inclusive, or lures you with a no-invoice low price, then charges extra later for "paying tax" or "issuing an invoice." They may also play word games on exchange-rate settlement, so you quietly overpay or fall into a compliance trap.

How It Works

Tax side

1. Tax-exclusive trap — the quote is a low tax-exclusive price; you think you got a deal. When it's time to clear customs for export, you need a VAT invoice (fapiao), and only then the factory says "an invoice costs 13% VAT extra."
2. Consequences of no invoice:
   • Can't legally clear customs or claim export tax rebates.
   • Funds can't settle through legitimate forex channels (corporate accounts need a real trade background to receive foreign exchange).
   • You may be pushed toward personal accounts or underground money changers — non-compliant.
3. Invoice-type confusion — special VAT invoice vs. ordinary invoice, with different rates (13%, 9%, 6%, 3% for small-scale taxpayers), deliberately left unclear at quoting.

Exchange-rate side

1. Offshore-rate trap — quoting USD using an exchange rate worse than market, or a fixed rate unfavorable to you.
2. Volatility dumped on you — after signing, demanding a price adjustment because "the RMB appreciated / USD depreciated."
3. Vague settlement currency — not specifying USD or CNY, or which day's rate applies.

Why It's Harmful

• Inflated cost — back-tax and exchange-rate gaps push the real cost far above the quote.
• Compliance risk — no invoice + personal-account payment can drag you into tax evasion, money laundering, or forex violations.
• Export blockage — without proper invoices, the whole chain of customs clearance, tax rebate, and forex verification is blocked.

Red Flags

• The quote doesn't say "tax-inclusive / tax-exclusive."
• Vague about "can you issue an invoice," or says "invoices cost extra."
• Suggests personal accounts, underground money changers, or offshore accounts.
• Exchange-rate terms are unclear or clearly off-market.

Solutions

1. Clarify price terms (mandatory)

• Every quote must explicitly state:
  • Tax-inclusive / tax-exclusive (with 13% VAT)
  • Incoterm (FOB / CIF / DDP, etc.)
  • Currency (USD / CNY)
• Reject any vague quote.

2. Insist on an invoice

• Require a special VAT invoice with a header matching the contract.
• The tax rate must be stated (13% for general taxpayers is standard).
• The invoice is the basis for lawful customs clearance, rebate, and forex settlement — it can't be skipped.

3. Lock the exchange rate

• The contract must specify the settlement currency and the rate mechanism (e.g., "settled at the Bank of China mid-rate on the payment date").
• For large orders, consider forward settlement or rate locking to hedge volatility.

4. Demand an all-in price

• Have the supplier quote an all-in price: tax-inclusive, packaging-inclusive, and including port-delivery logistics, to eliminate any later "back-tax" or "extra fee."

5. Settle via compliant channels

• Insist on corporate account + legitimate forex channels.
• Settle large orders via bank T/T or L/C, keeping the full document chain.
