How a Buyer Shortlisted R290 Heat Pump Suppliers in China
A buyer was looking for China-based suppliers of R290 heat pumps and wanted help narrowing down options by certification, factory profile, and model-level verification. SourcingX compared candidate products and suppliers, then highlighted where specifications still needed confirmation before a shortlist could be finalized.
The Buyer’s Request
Find China B2B suppliers for R290 heat pumps. Prioritize suppliers offering R290 propane refrigerant heat pump systems, and verify model-specific heating capacity, COP, operating ambient range, certifications, MOQ, lead time, and export experience.
What SourcingX Analyzed
- Supplier type and factory/trading-company classification
- Listed certifications for candidate products
- Refrigerant and heat-source configuration
- MOQ and lead time
- Price range across shortlisted products
- Model-level verification needs for capacity and COP
Key Findings
The following findings were identified from the data reviewed for this sourcing task.
Two candidate products were compared with different supplier profiles
The comparison covered two R290 heat pump products: one listed as a manufacturer/factory and the other as a trading company.
Why it matters: Supplier type can affect factory access, product control, and how quickly a buyer can validate technical details.
Note: This reflects the listed platform information; a deeper factory verification was not confirmed in the trace.
Both candidates showed low-entry commercial terms
Each product listed MOQ 1 and a 23-day lead time, with the first product priced at $1,470–$1,630 and the second at $1,759–$2,188.
Why it matters: These terms make it easier for a buyer to request samples or start a small test order before scaling.
Note: Pricing was shown as listed ranges on the platform and should still be confirmed with the supplier.
Certification evidence was present, but model-level confirmation was still needed
The first product listed CE, ISOCCC, CB, and RoHS, while the second listed CE, RoHS, CCC, ISOCB, and SASO.
Why it matters: Certification coverage is a key filter for heat pump sourcing, especially when the buyer needs compliance confidence before contacting suppliers.
Note: The trace also noted that model-specific certification evidence for the first product should still be confirmed.
One product clearly stated R290 refrigerant, while the other did not
The second product explicitly listed R290 refrigerant and air-source plus water-source operation, while the first product did not show a refrigerant value in the comparison.
Why it matters: For a buyer prioritizing R290 refrigerant systems, missing refrigerant detail is a critical gap that can affect shortlist quality.
Note: The first product may still have an R290 configuration, but that was not confirmed in the trace.
The search returned a larger supplier pool than the two products shown in the comparison
The offline search summary reported 30 suppliers and 62 products, with 24 of 30 suppliers showing system certification hits.
Why it matters: A broader pool gives the buyer more alternatives, but it also means the shortlist should be narrowed using the buyer's technical and compliance criteria.
Note: Only a subset of the ranked results was shown in the trace, so the public page should not imply a final ranking beyond what was reviewed.

Data Reviewed and Notes
Data reviewed
- Buyer request for R290 heat pump suppliers
- Offline product-search result set and supplier summary
- Two-product comparison report
- Ranked supplier output preview
Limits to keep in mind
- The trace did not confirm a final supplier selection or purchase decision.
- Export experience was requested, but it was not clearly verified in the reviewed result details.
- Model-specific heating capacity, COP, and ambient-range data were not confirmed in the comparison output.
- Only a subset of supplier records and product details was visible in the source trace.
Recommended Next Steps
Based on the available findings, the buyer could consider the following actions:
- Request datasheets for the shortlisted products to confirm heating capacity, COP, and operating ambient range.
- Ask for proof that the first product is truly R290-based and not only similar in naming.
- Verify certification documents for each model, not just the supplier listing.
- Confirm whether the trading company can provide direct factory documentation and sample support.
- Compare shipping terms, warranty coverage, and after-sales support before final shortlist approval.
