Trade between the two countries is heavy and well established, which is good news if you are building a business around china singapore import export. Container routes are frequent, the paperwork is largely digital on the Singapore side, and both markets are used to dealing with each other. That said, the details trip up newcomers: which permits you need, when duties and Goods and Services Tax apply, how your documents must match, and how to get paid safely across the border. This guide gives you the shape of the process both ways, so you know what to prepare and which authority to confirm the current rules with.
This is general information, not personalised legal, tax, or customs advice. Duties, thresholds, controlled-goods lists, and forex rules change on both sides, so verify current requirements with Singapore Customs, IRAS, and Enterprise Singapore on the Singapore side, and with Chinese Customs and the relevant Chinese authorities, or the Chinese Embassy or Consulate in Singapore, on the China side.
Getting Set Up to Trade
Before your first shipment moves, put the foundations in place. In Singapore you will typically:
- Register a business entity with ACRA, usually a private limited company, so you can invoice and hold a trading account.
- Activate a Customs Account with Singapore Customs. Almost every importer and exporter needs this to transact.
- Apply for permits through TradeNet, Singapore’s single electronic window for trade declarations, either directly or through a declaring agent or freight forwarder.
Enterprise Singapore is the government agency that supports companies trading internationally and can point you to schemes for market entry and capability building. On the China side, your supplier or buyer will have their own customs registration and declaration obligations, so agree early on who handles the export formalities in China and who handles the import formalities in Singapore, and vice versa.
Duties, GST, and Classifying Your Goods
Every product you move has a Harmonised System (HS) code, and that code drives how the goods are treated at the border, including duty and any controls. Singapore is a largely free-trade port, so many goods attract no customs duty, but a specific set of categories does, and imports are generally subject to Goods and Services Tax. Do not assume a rate from memory: check the current GST rate and the duty status for your exact HS code with Singapore Customs and IRAS, because these are updated and the classification detail matters.
Working out landed cost matters more than founders expect. The elements usually include:
- The supplier price and the agreed Incoterms, which decide who pays freight, insurance, and which customs charges.
- Freight and insurance to Singapore.
- Any customs duty on dutiable goods, plus GST on the import.
- Handling, storage, and your forwarder’s fees.
On the China side, exports may involve their own procedures and, for some goods, VAT and rebate mechanics handled under Chinese rules. Confirm those with the relevant Chinese authorities or a licensed agent in China, since they differ by product and by city.
Documents That Must Line Up
Cross-border trade lives and dies on paperwork that matches. A mismatch between the invoice, the packing list, and the permit is the most common cause of a held shipment. The table below shows the core documents and who usually issues them, so you can see what to collect for a typical shipment in either direction.
| Document | Issued by | Purpose | Watch-out for China trade |
|---|---|---|---|
| Commercial invoice | Seller | States value, terms, and parties | Value and description must match the permit |
| Packing list | Seller | Details cartons, weights, contents | Quantities must match invoice exactly |
| Bill of lading or air waybill | Carrier | Title and transport contract | Consignee details must be correct |
| Import or export permit | Via TradeNet (SG side) | Legal clearance to move goods | HS code must match the actual goods |
| Certificate of origin | Authorised body | Proves where goods were made | May affect preferential treatment |
For goods that need it, you may also require health, safety, or product certificates. Chinese buyers frequently ask for documents to be notarised or legalised, so if you are exporting from Singapore, factor in time to have corporate or product documents translated and authenticated for use in China.
Controlled Goods and Both-Sides Compliance
Some goods are controlled, restricted, or prohibited, and the lists are not identical between the two countries. Food, health products, pharmaceuticals, telecommunications equipment, certain chemicals, and dual-use items commonly carry extra approvals. Before you buy or sell, confirm on the Singapore side with Singapore Customs and the relevant controlling agency whether your item needs a special licence, and on the China side confirm import or export eligibility and any inspection or certification with Chinese Customs and the relevant Chinese authorities. What is freely tradable in one market may be restricted in the other, so check both directions.
Keep clean records of every declaration, invoice, and permit. Singapore Customs expects traders to retain trade documents for a set period and to be able to produce them, so treat good record-keeping as part of the business, not an afterthought.
Payment, Logistics, and Managing Risk
Getting paid across the border is its own discipline. New trading relationships often start with more conservative terms, such as a deposit with balance before shipment, or a letter of credit, before moving to open account once trust is built. Because moving funds out of the mainland is governed by China’s foreign exchange framework under SAFE, the State Administration of Foreign Exchange, your Chinese counterpart may face documentation requirements on their side, so agree the payment mechanics early and confirm current forex rules with the Chinese authorities.
A few habits reduce risk:
- Match your Incoterms to your actual capabilities, so you are not liable for legs of the journey you cannot control.
- Insure high-value shipments rather than self-insuring by hope.
- Use a reputable freight forwarder or declaring agent for your first shipments while you learn the process.
- Reconcile every shipment’s documents before it sails or flies, not after it is held.
Start small, get one clean shipment through in each direction, and scale once your documents, permits, and payment flow are proven. The system rewards traders who are precise.
