What is an HS code and why does it matter?

The Harmonized System code is the international product classification customs uses worldwide to apply duty rates, import restrictions, and statistics. The same product can carry different duty under different codes, so a wrong or lazy classification either overcharges you or exposes you to penalties on inspection. Classify deliberately — from your country's official tariff lookup — and keep the code consistent across invoice, transport document, and declaration.

Import duty & paperwork: what your shipment needs to clear customs.

Q: Do I pay customs duties in China or in my own country?

Export side: China's export formalities are normally handled as part of the export declaration and are not your cost item to manage — the exporter of record files them. Import side: duties, taxes, and clearance fees are charged by your own country's customs authority when the goods arrive, and they are based on the declared value, the HS classification, and your country's tariff schedule for that code. Check your national customs website for the actual rate before you order.

Q: What documents do I need to import from China?

The core set for most small shipments: a commercial invoice (value, seller, buyer, terms), a packing list (cartons, weights, dimensions), the transport document (bill of lading for sea, air waybill for air), and product-specific certificates where your market requires them — plus the HS classification your customs authority uses to apply duty. Your forwarder or exporter of record prepares the export side; the invoice accuracy on your side is what customs in your country checks.

The goods are made, inspected, and boxed — the last thing standing between you and your order is a stack of documents and your own country's customs. Here's the small-buyer version, without the freight-forwarder jargon.

Check your paperwork

Export documents for a small shipment prepared in Shanghai — Four documents decide whether your boxes sail through or sit in a warehouse.

First: duty is paid at your end, not ours

Two sides, two jobs. On the export side, China's export formalities are filed by the exporter of record — that's the structure discussed in export agency vs. buyout, and it's not a cost you manage. On the import side, your own country's customs charges duty and taxes when the goods arrive, based on the declared value, the product's HS classification, and your country's tariff schedule. Nobody in Shanghai can tell you your duty rate — your national customs website can. Always check it before you order, not when the boxes land.

The core document set

Commercial invoice. The value declaration: seller, buyer, goods description, unit prices, totals, and trade terms. This is the number your customs duty is computed from — and the single most abused document in shipping. It must be true.
Packing list. Cartons, contents per carton, gross and net weights, dimensions. Customs and your forwarder use it to check what's physically there.
Transport document. Bill of lading (sea) or air waybill (air) — the contract of carriage and the document you (or your bank/agent) need to take delivery.
HS classification. The product code your customs authority uses to apply duty. See below — this is where small buyers most often overpay or trip an inspection.
Product-specific certificates. Depending on product and market: origin certificates, safety or compliance marks, labeling approvals. These are your market's requirements, not China's — verify with your national authority or a licensed broker before production, so labels and tests are built into the run instead of bolted on after.

HS codes: the expensive detail

The Harmonized System is the worldwide product classification customs uses to set duty rates and spot restricted goods. The same product can carry different duty under different codes, and a lazy description ("plastic goods") invites either overpayment or an inspection penalty. Two habits keep you safe:

Classify deliberately from your country's official tariff lookup — for US imports that's the USITC HTS database; most countries publish an equivalent. It's free and takes minutes.
Keep it consistent across invoice, packing list, and transport document. Mismatched codes are the most common reason small shipments get pulled for inspection.

Three small-buyer traps

Under-invoicing "to save duty." If it's found, the penalties, delays, and record flag cost far more than the duty saved — and honest agents won't touch it. We don't.
Discovering certificates after production. If your market needs a mark or test, it must be planned into the run. Retrofitting means redoing goods.
Assuming freight quotes include duty and clearance. They almost never do. Ask what's included before comparing quotes — apples to apples.

The export side of your shipment — declaration, licensed structure, documents in your name — is part of our sourcing & export service. The import-side check (your country's rate and rules) stays with you by design, guided by the safeguards page. That division is what keeps your exposure honest.

Common questions

Do I pay customs duties in China or in my own country?

In your own country. China's export formalities are filed by the exporter of record; duty and taxes are charged by your customs when goods arrive, based on declared value, HS code, and your tariff schedule. Check your national customs site before ordering.

What documents do I need to import from China?

Commercial invoice, packing list, transport document (B/L or air waybill), HS classification, and any product-specific certificates your market requires. Your exporter/forwarder prepares the export side; invoice accuracy is what your customs checks.

The worldwide product classification customs uses to set duty and spot restrictions. Wrong codes mean overpayment or inspection penalties — classify deliberately from your country's official tariff database and keep the code consistent across all documents.
