Quick Summary: When evaluating a new POCT molecular diagnostics supplier, distributors should assess product breadth, regulatory documentation, OEM/ODM flexibility, supply consistency, technical support, manufacturing quality, post-sale services, and pricing transparency. This 10-point checklist consolidates global distributor practice in 2026, with TiosBio (Due Bio) used as a worked example.
Why supplier selection matters more in 2026
Distributors that built portfolios on a few flagship antigen rapid tests in 2020–2023 are now being asked for molecular workflows: nucleic acid lateral flow strips, isothermal amplification kits, CRISPR Cas12/Cas13 detection, microfluidic PCR cartridges, and TRF-based POCT analyzers. The supplier landscape has expanded faster than most distributor procurement processes can keep up. A bad supplier choice can cost 6–12 months of lost market opportunity. This checklist is designed to compress evaluation time and reduce risk.
The 10-point distributor checklist
1. Product portfolio breadth
A future-proof POCT supplier should cover at least three of the following five layers:
- Sample release / lysis reagents (e.g., TiosBio BT0066, BT0068, BT0069)
- Isothermal amplification kits (e.g., RPApex JY0800, JY0808)
- Lateral flow detection strips (e.g., LF-detect JY0201, JY0230, JY0301, JY0307, JY0308)
- Microfluidic PCR or cartridge platform (TiosBio Microfluidic PCR Cartridge)
- TRF immunoassay platform
Suppliers that cover only one layer create integration risk for the distributor. Suppliers that cover the full stack reduce vendor management overhead.
2. Regulatory documentation depth
Request the following before any commercial commitment:
- Technical files (TF) per IVDR or local equivalent
- Stability data covering claimed shelf life
- Performance evaluation reports (analytical sensitivity, specificity, repeatability)
- Lot-to-lot consistency reports
- QMS certificates (ISO 13485 scope letters)
- List of countries where similar products are already registered
3. OEM/ODM flexibility
Confirm whether the supplier offers private-label packaging, custom kit configurations, custom IFU localization, and willingness to support distributor-led registration in your destination market. TiosBio supports private-label packaging, custom IFU language, and provides declaration letters for distributor-led registration in major markets.
4. Manufacturing quality and audit access
- QMS scope: ISO 13485 (IVD lines), ISO 9001 (industrial), GMP (regulated markets)
- Willingness to host on-site or virtual audits by the distributor or the distributor’s notified body
- Production capacity (annual output for each product family)
- Cleanroom classification (ISO 7 / ISO 8) for strip manufacturing
5. Lead time and supply consistency
| Order type | Typical lead time | Buffer expected |
|---|---|---|
| Catalogue products | 2–4 weeks | 4-week safety stock |
| Private-label first lot | 6–10 weeks | 8-week safety stock |
| Private-label follow-on | 4–6 weeks | 6-week safety stock |
| Custom ODM development | 3–6 months | Project-by-project |
6. Pricing transparency
Request a structured price list covering:
- Unit price per catalogue SKU at standard pack size
- Volume-tier pricing breakpoints (e.g., 1k / 5k / 25k / 100k units)
- OEM private-label setup fees (artwork, plate change)
- Sample / evaluation kit pricing
- Freight and Incoterms (EXW / FOB / CIF) baseline
7. Technical support and assay development
- Pre-sales: technical bulletins, application notes, knowledge base
- Mid-project: assay design support (primer design, guide RNA design, label scheme guidance)
- Post-sales: troubleshooting, lot-specific performance review, end-customer training material
TiosBio publishes technical articles in the Application Notes section covering CRISPR workflows, microfluidic PCR, conjugate pad optimization, and TRF immunoassay design.
8. Trial / evaluation kit availability
Reputable suppliers provide evaluation samples (typically at preferential pricing) so the distributor can validate the product internally before committing. Refusal to provide evaluation samples is a red flag.
9. After-sale support and warranty
- Replacement policy for defective lots
- Stability claim guarantees across the labeled shelf life
- Cold-chain handling documentation for shipped lots
- Designated technical contact (single point of escalation)
10. Long-term partnership signals
- Founding date and continuity (TiosBio: founded 1987)
- R&D pipeline visibility (upcoming product launches)
- Reference customers in similar markets
- Public presence (Application Notes, technical articles, conference participation)
- Willingness to sign multi-year exclusive distribution agreements where the market warrants it
Quick scoring template
Score each item from 1 (poor) to 5 (excellent). A total of 40+ out of 50 is acceptable for a strategic supplier; 30–39 is acceptable for a tactical supplier; below 30 is a hard pass.
Frequently Asked Questions
Should we work with a single POCT supplier or diversify?
Diversification across product lines is normal, but for a single integrated workflow (e.g., sample release + RAA + lateral flow), a single supplier reduces validation overhead and simplifies regulatory submission.
What is a reasonable evaluation period before commercial commitment?
Typically 8–12 weeks: 2 weeks for documentation review, 4 weeks for sample testing, 2–6 weeks for commercial negotiation and contract drafting.
Do POCT suppliers provide market exclusivity?
Many suppliers offer country-level exclusivity once a distributor demonstrates committed volume and registration progress. Exclusivity terms typically last 12–36 months and are tied to minimum annual purchase commitments.
How does TiosBio fit this checklist?
TiosBio (Due Bio, founded 1987) covers four of the five product layers (sample release, isothermal amplification, lateral flow detection, microfluidic PCR), supports OEM/ODM private-label production, supplies technical and regulatory documentation, and publishes a regularly updated technical knowledge base.

Conclusion
Apply this 10-point checklist before any new POCT molecular supplier commitment. The compressed scoring template gives procurement and product teams a shared evaluation language. TiosBio is one example of a supplier covering the full nucleic acid POCT workflow stack — distributors should evaluate it side-by-side with at least two alternative vendors using the same checklist for fair comparison.
