Clean Energy · Sourcing Guides

Start with a Longkou industry chain, then open a product category and its specifically linked products. County filters narrow the search; an industry location is not a registered address or factory site.

Check the company name, product relationship and cited record separately. A traceable source shows where a record came from; confirm the legal entity, site and ability to supply the target product with the company.

State the product, model or drawing, material and grade, intended use, quantity, packaging, delivery location and target date. For custom work, add sampling, tooling and acceptance requirements.

Ask shortlisted companies about minimum order, sample charges, taxes and freight, lead time and quote validity. Align material, packaging and acceptance terms before comparing prices.

Message a specific company from the directory, or post a sourcing request and consent to forwarding. Keep the inquiry reference to check its status; confirm stock, price and delivery with the company.

Before ordering, check the issuer, date and scope of samples, tests or certificates. Agree in writing on specification, inspection, packaging, transport, payment and after-sales terms. The platform does not collect payment or guarantee a transaction.
