Importing chargers from China is a repeatable order journey once the documents and terms are aligned: the proforma invoice starts it, the payment structure funds it, the Incoterm decides who carries which cost and risk, and customs plus quality checks close it. This guide walks from the PI to the port — what each document does, how first-order payment usually works, how to choose the right Incoterm, what customs and logistics require, and how to check quality before and after shipment.
Key takeaways
- The proforma invoice is the order's contract draft: product, quantity, unit price, Incoterm and delivery window.
- Landed cost under the same Incoterm is the number that matters when comparing quotes.
- QC before shipment plus a document check at receipt keeps reorders consistent.

Starting With a Clear Proforma Invoice
The proforma invoice (PI) is the seller's formal quotation and the basis of the order. A useful PI names the product and model, quantity, unit price, total value, the Incoterm, the payment terms, the delivery window and the shipping destination. Every field is a control point: the model number should match the certificate, the Incoterm should match the price basis, and the delivery window should match your stock plan.
Review the PI against the approved sample before signing. A PI that lists a different model, a vague Incoterm or an open delivery window is not ready to fund. Corrections are cheaper before payment than after.
The order file grows around the PI. Once signed, it should hold the approved sample reference, the model-specific certificates, the packing-list template and the pre-shipment inspection scope. Every later step — payment, shipping, customs and receipt — reads from this file, so keeping it current is what turns the import into a repeatable process instead of a series of one-off decisions.
Version control is the quiet rule of the order file. When the PI is amended, the sample changes, or a certificate is updated, the file should show the change with a date, so every step reads the current version rather than an old one. Imports fail on stale documents more often than on bad products; a versioned file removes that failure mode.
Payment Structures for First Orders
First orders in cross-border charger importing commonly use staged payment: a deposit with the balance before shipment. Larger programs may use letters of credit or documents against payment, and samples often use lighter methods. The exact structure is negotiated and confirmed in writing per order — the payment methods page at WECENT documents the accepted structures, and the terms for your order are confirmed on the PI.
Two habits protect the buyer:
- Never pay the full balance before seeing the shipment inspection result. The balance-before-shipment structure exists to protect both sides.
- Keep the payment method aligned to the order size. A bank transfer for a container and a lighter method for a sample are different risk profiles.
Currency and timing deserve a line in the same plan. Cross-border quotes are usually priced in one currency, and the exchange rate between quote and payment can move the landed cost; locking the currency on the PI removes one variable. Timing matters because the payment schedule and the production schedule are linked — a deposit starts production, and the balance release is tied to the shipment step. Agree both on the PI so that a payment delay does not become a shipping delay.
Choosing the Right Incoterm
The Incoterm defines who pays for freight, insurance and duties, and when risk transfers from seller to buyer. The choice changes the landed cost even when the unit price is the same, so quotes must be compared under the same term.
| Incoterm | What the seller covers | What the buyer covers |
|---|---|---|
| EXW | Goods at the factory | All transport, export and import formalities |
| FOB | Goods to the loading port and export formalities | Ocean freight, insurance and import |
| CIF | Goods to the destination port plus insurance | Import duties and inland delivery |
| DDP | Goods delivered to the buyer's door, duties paid | Receiving at the door |
The table is a summary, not legal advice — confirm the exact obligations for the chosen term. The buyer who compares quotes at the same Incoterm avoids the classic trap of a low FOB price that becomes a high landed cost after freight and duties.
Logistics, Customs and Documentation
The customs file for a charger import typically includes the commercial invoice, packing list, bill of lading or airway bill, and the documents required for the destination market — certificates and test reports are often part of the import file, not just the sales file. Requirements vary by country and product, so confirm the current list with the freight forwarder or customs broker before shipping.
Two planning points keep the shipment on schedule:
- Confirm the model-to-certificate match before booking freight. A certificate that names a different model is an import problem, not a paperwork detail.
- Plan for inspection at the destination. Sampling and testing at receipt catch what the factory's outgoing check may have missed.
Three product-level details belong in the customs plan, with local advice confirming the specifics: the HS code classification for the charger type, the destination-market plug and packaging compliance, and any transport restrictions on the batteries inside the products. Each of the three varies by country and product, which is why the forwarder and broker confirm them per shipment rather than once per catalog.
Freight mode is part of the plan. Air freight is faster and more expensive; sea freight is the volume economics for containers but adds weeks and ties up capital in transit. The choice follows the order size and the stock plan, and the delivery window on the PI should match the mode. For a first order, many buyers use a smaller air shipment to validate the product and the process, then move to sea freight once the line is proven.
QC Before and After Shipment
Quality control has two sides in an import program: pre-shipment and at receipt. Pre-shipment inspection checks units, packaging and paperwork against the approved sample and the PI; it is the moment to catch labeling, quantity and configuration mismatches. At receipt, the buyer repeats the key checks — model, certificates, function and packaging — and logs the results with the batch records.
The inspection scope should be written before the order, not improvised at the factory. Decide what is checked — configuration, function, appearance, packaging, labeling — and how units are sampled, so the same standard applies to every batch. This is the same discipline as the production test flow the supplier publishes: incoming checks, functional testing and aging where the line requires it, and an outgoing inspection before shipment. The details are confirmed per order, but the framework should be agreed up front.
Consolidation is a planning lever for multi-model orders. When several SKUs ship together, a consolidated container changes both freight and customs handling per unit; the packing list should name every model and quantity so the batch records can be matched at receipt. The model-to-certificate check then runs once per line, which is faster and cleaner than tracing mixed cartons later.
How WECENT runs order files for imports: In import programs, the order file is the working document: PI, approved sample reference, pre-shipment inspection report, batch records and the receipt check. When every step names the same configuration, the reorder is a repeat, not a new gamble.
For the product side of an import, the WECENT homepage and the factory page describe the manufacturing and quality context, and the Quality Control page documents the production test flow. To start an import order cleanly, send the target markets, product mix and volume expectations to WECENT's project engineering team — the review returns an order structure with the PI fields, payment terms and inspection plan for the configuration.
Frequently Asked Questions
What is the difference between FOB and DDP for a charger import?
FOB transfers risk and cost responsibility at the loading port; DDP delivers the goods to your door with duties paid. The choice changes landed cost and who handles each step — compare quotes under the same Incoterm.
How long does a charger import take?
It depends on production lead time, the shipping mode and customs clearance at both ends. Confirm the delivery window on the PI and plan buffer for the first order, since the first shipment usually teaches the process.
What documents do I need for customs?
Typically the commercial invoice, packing list and transport document, plus any market-required certificates and test reports. Confirm the exact list with your forwarder or broker for the destination country.
Why does the model number on the certificate matter for import?
Customs and the market both check that the imported product matches its documentation. A certificate naming a different model can stop the shipment or create compliance problems after entry.
How do I protect myself on the first order?
Align the PI, payment structure, Incoterm and inspection plan before paying; use a pre-shipment inspection; and check the shipment against the documents at receipt. The order file is the protection.
What should I prepare before starting an import conversation?
The target markets, the product mix and volumes, the desired Incoterm and the delivery window. With those four fields, a supplier can return an order structure — PI fields, payment terms and inspection plan — instead of a generic price list.
