What importers should confirm before placing a first order with a Chinese low voltage electrical manufacturer: OEM terms, compliance documents, HS classification, QC and shipping.
Most first orders from a Chinese electrical manufacturer fail for commercial reasons, not technical ones. The product is fine; the paperwork, the labelling or the freight terms were never agreed in writing. Here is the sequence that keeps a first order boring — which is exactly what you want.
A quotation is only as good as the input. Send rated voltage and frequency, rated current or breaking capacity, pole configuration, mounting standard (35 mm DIN rail, panel cut-out diameter, fixing centres), terminal capacity in mm², enclosure IP rating and the ambient temperature range. If you are replacing an existing part, send the manufacturer and model number of the part you are replacing and the ratings it must match.
For low voltage equipment entering the EU, the applicable directive is LVD 2014/35/EU and, where EMC applies, 2014/30/EU. The declaration of conformity is issued by the manufacturer and must list the harmonised standards applied, the responsible person in the EU and the manufacturer's identity. Ask for a copy of the current declaration for the exact model you are buying, not a generic one for the range, plus the test reports behind it. Where CB scheme certificates or RoHS test reports exist, request those too.
If your market is not the EU, state the destination country up front. Requirements differ materially between the EU, the UK, the Gulf, Brazil (INMETRO) and North America (UL/ETL), and retrofitting a compliance file after production is expensive.
"OEM available" means very little on its own. Define: whose model number appears on the product, whether the mould or tooling is dedicated, carton size and print, label content, barcode or QR requirement, master carton quantity, and who owns the tooling. Put all of it in the proforma invoice or a signed specification appendix. If you want your own model numbering, agree the numbering scheme before the first production run, because printed artwork is usually ordered in batches.
The HS heading depends on the product family, not the brand: circuit breakers, sockets, lamps and meters all sit in different headings, and the duty rate, licence requirement and inspection regime follow from that. Agree the code with your customs broker before shipment. For Incoterms, FOB Ningbo or Shanghai is the common starting point for a first order because it keeps control of the freight with you; ask for both FOB and CIF pricing so the difference is visible.
Ask for the pre-shipment inspection criteria table: what is measured, on how many pieces, and against which limits. For a first order a third-party inspection is cheap insurance. The shipping documents you should expect are the commercial invoice, packing list, bill of lading and, where applicable, a certificate of origin. Test reports travel by e-mail; keep them with the invoice because customs brokers ask for them.
Order a small quantity, install it, and confirm the mechanical details you could not check on a datasheet: does the DIN clip release cleanly, does the terminal accept your cable, does the label survive your warehouse. Then scale. This costs less than one air-freighted emergency shipment.
ELEHPD manufactures in Yueqing, Zhejiang and exports to distributors, panel builders and OEM buyers worldwide. If you send the specification of the part you are replacing, we will confirm the closest match, the compliance documents available for it and the lead time.
Send the ratings, dimensions and quantities you are working to and we will confirm the closest match from the ELEHPD catalogue, the compliance documents available for it and the lead time. OEM branding, private model numbering and buyer-specific cartons are available on qualified volumes.
