QC & Craftsmanship Standards for B2B Orders
Stable quality is not a slogan. It is a repeatable process: checkpoints, records, and release rules that protect your brand and reduce after-sales risk.
For OEM/ODM projects, QC starts from the approved sample and ends only when packing is verified. Explore OEM/ODM service here: OEM/ODM.
Our QC Philosophy
In B2B supply, quality is measured by repeatability. We treat each order as a program: specs are locked, processes are standardized, and inspection criteria are documented so your next reorder matches the last.
- Spec first: build to the approved sample and checklist—not “factory habit.”
- Process control: stop defects during production, not at the warehouse.
- Record & trace: lot tracking supports stable reorders and fast root-cause response.
- Packaging is QC: damage prevention is part of product quality.
QC Framework (What We Control)
Incoming Material Check
- Material consistency and visual grading (as applicable)
- Hardware and accessory verification (locks, zippers, fittings)
- Moisture/condition control for storage readiness (when required)
In-line Process QC
- Critical step checks to prevent cumulative defects
- Workmanship consistency (finish, assembly, fittings)
- Random sampling checkpoints per batch
Final QC & Release Rules
- Cosmetic inspection standard (surface, marks, color uniformity)
- Function check (fit, locks, moving parts, stability)
- Playability/setup check for instruments (where applicable)
- Only released after checklist sign-off
Packing Verification
- Carton integrity and internal protection confirmation
- Carton marks, barcodes/labels placement (if requested)
- Quantity verification and loading readiness
Packaging and delivery standards are documented here: Shipping / Delivery / Packaging.
Instrument QC Focus (String Instruments)
For instruments, QC must cover both appearance and performance. Our inspection points prioritize stable setup and consistent feel for your market tier.
Key Checkpoints
- Surface & finish: uniformity, dust points, scratches, edge consistency.
- Assembly & fit: seams, alignment, hardware seating, structural stability.
- Setup consistency: bridge shaping, string height, nut slots, tuning stability (as applicable).
- Playability check: basic response and functional performance verification by tier.
- Accessory match: bundles verified for completeness (case/bow/strings/rosin where relevant).
Accessories QC Focus (Bow / Case / Care)
Accessories affect user experience directly and often generate after-sales issues if not controlled. We inspect durability-critical components and packing protection.
Cases
- Shell integrity, surface defects, and edge finishing
- Zippers/locks/hinges function check
- Interior fit, padding consistency, and accessory compartments
- Handle & backpack system strength verification
Bows & Small Items
- Appearance, straightness, and basic balance feel (where applicable)
- Hair quality consistency and ferrule/eyelet finishing
- Hardware tightness and moving parts function check
- Small items packing protection to reduce damage in transit

Reports & Documentation (For Professional Procurement)
- QC checklist: configurable by product tier and your brand requirements.
- Photo confirmation: key checkpoints and packing status when requested.
- Lot traceability: supports repeat-order stability and fast problem isolation.
- OEM/ODM file control: artwork, packaging files, and approval records managed via the project workflow.
FAQ
Q1: Can you follow our QC standard or checklist?
A: Yes. We can align to your checklist and add brand-specific checkpoints for OEM/ODM programs.
Q2: How do you ensure reorder consistency?
A: We lock the approved sample and create a spec checklist, then maintain process checkpoints and lot records for repeat programs.
Q3: Can we request additional inspection photos or third-party inspection?
A: Yes. For certain orders, photo confirmation and third-party inspection can be arranged based on your procurement policy.
Q4: Is packaging included in QC?
A: Yes. We treat packing verification as part of final release to reduce transit damage and claims.
Build a Stable Supply Program
If you are sourcing for distribution or private label, we recommend starting with a simple brief so we can define QC priorities by tier.
- Product category and target tier (student / step-up / professional)
- Target market and sales channel
- Order plan (trial → repeat → program)
- Branding and packaging requirements
- Any specific defect concerns or standards you want to avoid
