Checklist

• Keep certificates current and filed against the exact model name.
• Retain one sealed sample carton from every batch for reference.
• Record the arrival condition with photographs on the day of delivery.
• Confirm the exact configuration in writing before the deposit is paid.
• Agree in advance who pays for return freight on a defect claim.
• Log sell through by account for the first eight weeks.

Commercial terms

Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.

Freight terms should be named explicitly, because an unclear incoterm is the fastest way to lose a relationship.

Frequently asked questions

Which coil resistance suits Onnix 4 best?

Higher resistance suits tighter draws and salt liquids; lower resistance suits open airflow and freebase blends.

What happens if a batch fails inspection?

The agreed procedure normally covers replacement of affected units or credit against the next order, documented before shipment.

Can several models be mixed in one shipment?

Yes, mixing models and flavours within a carton or pallet is common and usually helps first time buyers test demand.

Can packaging be adjusted for our market?

Artwork localisation is straightforward; structural changes need larger volumes and a longer lead time.

Final word

The buyers who do this well are not luckier; they are simply more consistent about the basics.
