MOQ & tiering: lock capacity before you lock price

What drives MOQ on 2g programs

Coating and assembly windows, color-match targets, and packaging tray availability often push 2g runs into higher tiers than 1g. Tie quotes to a dated production schedule and line capacity statement.

How to negotiate tiers

Request a three-tier matrix (pilot / scale-up / steady state) with unit price, cycle time, and scrap assumptions. Clarify whether cosmetic rework is included. For category navigation, start here → aces 2g in bulk.

Finish options and their impact

Brand coatings and foils affect cure time and yield. Agree on ΔE color tolerance and Taber/adhesion targets in the PO to avoid re-quotes later.

Forecast buffers: keeping launches on-time

Lead-time math that actually holds

Combine supplier cycle time with your inbound QA and labeling steps. Hold a rolling PO for hero SKUs and a 10–20% buffer for seasonality or promotions.

Rolling samples and retainers

Before each run, pull retain samples from the prior lot to confirm adhesion, gloss, and fit; this keeps variance low and prevents last-mile surprises.

When to split POs

For new finishes or tight timelines, split the first mass run into two drops to reduce exposure while you validate retail velocity.

Logistics & compliance: documents that speed acceptance

UN 38.3 test summaries for integrated cells

If the housing integrates a rechargeable cell, keep the exact cell/pack UN 38.3 test summary on file. U.S. PHMSA’s updated 2024 guidance standardizes required elements and clarifies availability. :contentReference[oaicite:2]{index=2}

IATA’s 2025 Lithium Battery Guidance aligns with the DGR and includes classification flowcharts, SoC practices, and example test summaries—use them to brief carriers and freight forwarders. :contentReference[oaicite:3]{index=3}

Safety practices to align with QA

Map supplier controls to IEC 62133-2 (portable lithium systems under intended use and reasonably foreseeable misuse) to reduce field failures and RMAs. :contentReference[oaicite:4]{index=4}

Warranty terms: define evidence, timelines, and thresholds

Cosmetic vs functional fail

Set separate criteria and remedies. Cosmetic: speckle/micro-scratch windows and polish/recoat rules. Functional: adhesion loss, cracked ports, or leak beyond tolerance bands.

Bench data you should require

Pressure-drop vs flow; output curves; heat-soak and altitude leak tests. Record test rigs and conditions so results are reproducible across lots.

Timelines and lot traceability

Agree on RMA response time (e.g., 5–7 business days), root-cause window, and replacements/credits process. Ensure serial/lot mapping back to coating line and oven profile.

Buyer checklist (clip into your PO)

• Specs & drawings: assembly drawings; o-ring durometers; cap compression; port reinforcement; window geometry.
• Bench methods: pressure-drop/output curves; heat-soak/altitude leak tests; pass/fail bands tied to your viscosity window.
• Docs: UN 38.3 test summary (if integrated cell); QA sheets; dielines; packaging tray counts and carton strength.
• Supply: MOQ tiers; cycle/lead time; warranty triggers; lot traceability; after-sales SLA and evidence requirements.
