Why Besos for B2B Programs

If you’re scaling a white-label or wholesale program, Besos hardware stands out for consistent housing tolerances, clean assembly paths, and predictable fit with standard ceramic cores. For storefronts and fulfillment teams, that translates into fewer DOAs, fewer leakage-related returns, and more repeat orders. If your catalog includes screen or non-screen variants, a focused SKU set reduces training and QC overhead while keeping replenishment simple—especially where master-case velocity matters.

Looking at switching costs? Keeping a compatible ecosystem across carts, disposables, and chargers makes mix-and-match replenishment easier when retail demand spikes. If you currently list premium alternatives like ACE Ultra Premium, Besos fills the “value-reliable” slot without compromising on the compliance cues buyers expect.

COA Essentials: What to Verify

A COA is only as credible as the laboratory behind it. Prefer reports issued by ISO/IEC 17025–accredited labs—this standard defines competence, impartiality, and consistent operation for testing/calibration laboratories, giving buyers defensible, repeatable results in audits and product complaints. Cross-check the accreditation body, scope, and validity dates on each report. :contentReference[oaicite:5]{index=5}

For empty hardware (no fill), a practical COA review should cover:

• Metals screening on wetted components (e.g., lead, cadmium, mercury, chromium). Request method notes and reporting limits. RoHS-aligned expectations help when selling into the EU. :contentReference[oaicite:6]{index=6}
• Organic residues (manufacturing residues, solvent traces) with method references and LOQs.
• Materials declarations (stainless grades, polymer resins, seals/gaskets) and any applicable extractables/leachables notes for intended temperature ranges.
• Battery safety data for integrated disposables (cell make/model, protection IC, and transport test references—see UN 38.3 section below).

Tip: insist on a complete sample trace (batch ID, sampling date, who sampled) and verify QR/serial ties back to your inbound cases. That linkage is critical when a retailer asks you to produce records within 24–48 hours.

ISTA 3A Packaging Notes (Parcel Systems)

Most DTC/wholesale replenishment for vape hardware rides small-parcel networks. ISTA 3A is designed precisely for individual packaged products moving through parcel delivery systems (air/ground) up to 70 kg, simulating drops, vibration, compression, and environmental cycles typical in UPS/FedEx/USPS style handling. Request the test plan and a short summary of results for your Besos master cases and inner packs. :contentReference[oaicite:7]{index=7}

What to ask your lab or packager for:

• Package style tested (standard/small/flat/elongated) and acceptance criteria (product/pack condition at test end). :contentReference[oaicite:8]{index=8}
• Drop heights/vibration profiles used and whether conditioning was applied.
• Number of samples (3A can be run with 1 sample; request rationale if sample size is minimal). :contentReference[oaicite:9]{index=9}

Why it matters: fewer transit-damage claims mean stable retailer relationships and less margin erosion. For export lanes, 3A documentation also accelerates claims with carriers and 3PLs.

Battery & UN 38.3 (If Applicable)

If your Besos configuration includes an integrated rechargeable cell (e.g., USB-C rechargeable disposable), logistics teams will expect a UN 38.3 Test Summary. The US PHMSA clarifies that lithium cells/batteries must pass the UN Manual of Tests and Criteria subsection 38.3; distributors should hold the updated Test Summary on file for each battery design. :contentReference[oaicite:10]{index=10}

When auditing supplier paperwork, confirm the battery model, protection circuitry, and the actual standard revision referenced (UNECE maintains current revisions). :contentReference[oaicite:11]{index=11}

Materials & RoHS Alignment

For cross-border programs, RoHS is still the simplest common denominator to communicate substance restrictions for EEE. The EU lists 10 restricted substances (Pb, Cd, Hg, Cr(VI), PBB, PBDE, DEHP, BBP, DBP, DIBP). Ask suppliers for materials declarations or third-party screenings that align to these limits where applicable. :contentReference[oaicite:12]{index=12}

RoHS-aligned messaging is not a cannabis-specific rule; it’s an electronics materials expectation that helps customs and retail compliance teams triage risk quickly. :contentReference[oaicite:13]{index=13}

Optional: Child-Resistant (CR) Packaging Classes

If your market or retail partners request CR features for outer packaging, use the ASTM D3475 classification language when engaging converters and labs. It provides a shared taxonomy across reclosable/non-reclosable types and is referenced by the US CPSC indices. :contentReference[oaicite:14]{index=14}

Spec Checklist You Can Copy

• Model & finish: Besos housing (finish/colorway), mouthpiece type, reservoir volume.
• Core compatibility: ceramic spec, target viscosities, recommended preheat/pulse ranges.
• QA artifacts: COA from ISO/IEC 17025-accredited lab; batch IDs and sampling notes. :contentReference[oaicite:15]{index=15}
• Transit docs: ISTA 3A summary for inner/outer packs; acceptance criteria. :contentReference[oaicite:16]{index=16}
• Battery (if any): UN 38.3 Test Summary with battery make/model and protection IC noted. :contentReference[oaicite:17]{index=17}
• Materials: RoHS-aligned declaration for metals/flame retardants/phthalates where applicable. :contentReference[oaicite:18]{index=18}

Quick FAQ for Procurement

Q: Do I need ISTA if I ship only pallets?
A: If your channel is primarily LTL pallets, ISTA 3A (parcel) may be less indicative; discuss alternatives (e.g., other ISTA projects) with your lab. For parcel-heavy flows, 3A is the right baseline. :contentReference[oaicite:19]{index=19}

Q: What if my vendor’s lab is not ISO/IEC 17025-accredited?
A: You can still review data, but for retailer audits and border checks, 17025 accreditation materially strengthens credibility and traceability. :contentReference[oaicite:20]{index=20}

Q: Where can I see Besos form factors before sampling?
A: Start with the brand hub and the disposable line overview here: Besos and besos disposable vape pages—they summarize housings, finishes, and MOQ options for B2B buyers.
