LiUNOVA supplies OEM/ODM architectural door hardware from verified factories in China, including locks, hinges, handles, cylinders, and complete door hardware sets for wooden, steel, and aluminium doors in residential, hospitality, and commercial projects. Ranges can be configured by lock type, backset, handle style, finish, cylinder system, and door standard, with project kitting for consistent installation across multiple units. LiUNOVA manages AQL-based QC on material/finish quality, machining accuracy, function testing, and packing completeness, with CFR / FCL export and consolidation alongside doors and other building materials in one LiUNOVA container (scope-dependent).

At Liunova, we focus on simple and reliable international shipping. All products are shipped directly from China’s major seaports to ports worldwide. Our main goal is to give buyers clear cost, safe transport, and predictable delivery time.
We mainly support the following international shipping terms:
1. CFR (Cost and Freight)
Most Recommended for Buyers
Under CFR, we handle:
- export customs clearance
- trucking from factory to port
- container loading
- sea freight cost
- vessel booking
Buyer only handles:
- destination port charges
- customs clearance in their country
- local delivery to warehouse
This method gives stable cost and easy planning for buyers.
2. FCL (Full Container Load)
Best option for bulk orders
FCL means the container is only for your goods.
It is safer, faster, and cheaper per unit.
We recommend FCL because it offers:
- lower freight cost
- faster customs clearance
- zero mixing with other shipments
- less damage risk
- better packing control
This is the ideal method for serious buyers and repeat orders.
3. LCL (Less than Container Load)
Available but not recommended
We only use LCL for:
- small test orders
- small mixed orders
- first-time sample shipments
Why we do not recommend it:
- higher cost per unit
- risk of mixing with other suppliers
- slower customs clearance
- higher VAT and inspection fees
- more chance of damage or missing cartons
FCL is always the better choice for long-term business.
4. EXW / FOB (Optional on Request)
Available for buyers who want to manage their own freight.
- EXW: Buyer handles pickup from factory
- FOB: We deliver goods to the Chinese port, and buyer pays sea freight
These terms are used less often because CFR and FCL provide better cost control.
Why Source with Liunova?

How is Liunova different from a normal sourcing agent?
Most agents focus on price and communication. Liunova is built as an end-to-end quality and compliance partner:
- We start with a technical brief (spec, standards, usage) instead of just a product photo.
- We work only with verified factories that have passed our internal audit.
- Every order is linked to a master specification + approved samples.
- We run independent QC at the factory before goods are shipped.
- We manage export documents and CFR/FCL shipping so the same team controls quality and logistics.
Therefore, you get one responsible partner for the entire process, not multiple disconnected middlemen.
How does your quality control (QC) process work in China?
Liunova uses a multi-stage QC system based on AQL:
- Pre-production – confirm raw materials, trims, tooling, artwork, labels and packaging against the approved spec.
- During-production inspection (DPI) – visit while production is running to check workmanship, dimensions and process control.
- Final random inspection (FRI) – AQL sampling on finished goods (critical / major / minor defects, measurements, appearance, function).
- Packing & labelling check – confirm inner/outer packing, barcodes, shipping marks and palletising.
Each inspection produces a written QC report with photos, measurement tables and defect statistics that you can review before shipment approval.
How do you keep quality stable when using many factories and product categories?
We work with a controlled supplier base, not open-market suppliers:
- New factories go through a vendor approval process (legal check, capacity, machines, export history, key customers).
- We create a Liunova QC checklist for each product type (textiles, machinery, chemicals, building materials, etc.).
- Approved golden samples and lab reports are stored and used as the reference for repeat orders.
- Supplier performance (defect rate, on-time delivery, response speed) is tracked so that poor-performing factories are corrected or replaced.
This turns a fragmented China supply base into a managed, measurable network for our clients.
Can I see QC reports, test results and photos before shipment?
Yes. Transparency is a core part of our model:
- For each inspected order you receive a full QC report with:
- Inspection date, location and AQL level
- Photos of goods, labels, packing and any defects
- Measurement sheets and functional test results
- Where lab testing is required (e.g. OEKO-TEX, REACH-related, CE-type tests), we share copies of certificates and test reports.
No shipment is released without your written confirmation when critical issues are found.
How do you handle non-conforming or failed inspections?
If an order fails our agreed QC criteria:
- The shipment is put on hold and the buyer is informed immediately.
- We issue a non-conformity report listing the exact problems and root-cause feedback from the factory.
- Corrective actions can include rework, sorting, replacement production or commercial compensation, depending on severity and timing.
- A re-inspection is arranged to confirm that corrective actions were effective before goods are loaded.
This process protects you from quietly shipped problem goods and surprise claims at destination.
How do you manage compliance (CE, REACH, OEKO-TEX, FDA, etc.) for different products?
Compliance is treated as part of QC, not an afterthought:
- During factory approval we check existing certificates and test reports for scope, validity dates and issuing bodies.
- For new projects we align product spec, test plan and documentation at the quotation stage (not after production).
- Where required, we coordinate third-party lab testing and ensure reports match the exact product and batch produced.
- For chemicals and lubricants we ensure MSDS/TDS, hazard labelling and UN packaging are correctly prepared before shipment.
This reduces the risk of customs issues, retailer rejections and liability problems in your home market.
What part of QC is linked to packing, loading and shipping?
Quality does not stop at the factory gate. Liunova also controls:
- Carton strength, packing method and palletising to reduce transit damage.
- Container loading checks (for key projects) to verify carton count, container condition and securing of cargo.
- Accuracy of export documents (CI, PL, HS codes, weight/volume) to avoid customs queries and port delays.
Because we combine QC + CFR/FCL logistics, we can track your order from production line to port, giving a more secure and professional sourcing experience than simple price-based agents.
