FAQ
Buyer questions
Who is the seller?
The manufacturing plant. CompressorB2B is the English specification desk and RFQ router — not a trading company.
Do you sell as a trader?
No. The plant remains the seller. CompressorB2B is the English specification desk and RFQ router.
What HS code applies?
Most air compressors ship under HS 8414. The packing list states the commodity code and wood treatment.
Are listed plants verified factories?
No. Listing is from public factory data and files we hold. It is not a factory-verification badge or exclusive agency. Plants that finish onboarding receive RFQs in the factory desk.
