Materials & Certification
A trigger-based compliance framework — built to AU/NZ standards, available to wholesalers worldwide.
MJK Furniture is an OEM/ODM children's furniture manufacturer operating from a 3,000 m² industrial-CNC factory in Xuzhou, China. Since 2015, we have produced wood storage, shelves, lockers, tables, and chairs for B2B wholesalers and educational space design firms, with products designed for Montessori-aligned classroom environments.
Our compliance approach is intentionally different from most factories of our size. We do not claim per-product certifications we have not earned. We document what our material suppliers hold, we trigger third-party testing for qualifying orders when buyers need formal proof, and we openly state what we do not claim.
This page documents three things, in order of evidentiary weight: what our suppliers hold (Section 2), what we trigger for qualifying orders via accredited labs (Section 3), and what we will not tell you we have (Section 4). If you are evaluating MJK as a supplier, this page is designed to give you everything you would otherwise have to ask for in a 30-minute call.
Supplier-Held Certifications
Our primary plywood supplier (referred to throughout this page as "the mill") holds the following certifications. We do not claim these certifications as our own. We attribute them to the supplier, with verification paths where independently confirmable. Unredacted scans are available under NDA after supply agreement.
Plywood Mill: CARB Phase 2 Verified
The mill is CARB Phase 2 registered with Mill No. ICTT-18073, verifiable on the California Air Resources Board's public registry. This registration covers Hardwood Plywood with Veneer Core (HWPW-VC) — the substrate used in MJK's storage, shelf, and locker products.
The mill additionally holds the following certifications. All scans are available under NDA after supply agreement; the CARB registration is additionally verifiable on the public CARB.ca.gov registry without NDA:
| Certification | Authority | Scope | Verification |
|---|---|---|---|
| FSC Chain-of-Custody | FSC C141103 | Wood traceability (supplier-held) | Scan under NDA |
| CARB Phase 2 | California ARB | Formaldehyde emission, plywood (Mill No. ICTT-18073) | Public registry at CARB.ca.gov + scan under NDA |
| EPA TSCA Title VI | US EPA | Federal formaldehyde, plywood | Scan under NDA |
| EUTR | European Commission | EU Timber Regulation due diligence | Scan under NDA |
| F17 / AS/NZS 2269 | Standards Australia/NZ | Structural plywood | Scan under NDA |
| ISO 9001 | International | Quality management system | Scan under NDA |
Independent Test Report (Q1 2026, Quarterly)
The most recent quarterly test was performed by Shanghai Hongjun Science & Technology Co., Ltd. (SHST)— a laboratory accredited by:
- IAS (International Accreditation Service)
- ilac-MRA (International Laboratory Accreditation Cooperation — Mutual Recognition Arrangement)
- CARB & EPA TPC-43 (Third-Party Certifier authorization, subcontractor to ICTT Corporation)
Sample chain of custody for this report:
| Stage | Date | Notes |
|---|---|---|
| Production | 2026-03-10 | Mill production batch |
| Sampling | 2026-03-20 | Sampled by SHST representative per ATCM regulation (not self-supplied) |
| Receipt | 2026-03-24 | At SHST testing facility |
| Test window | 2026-03-24 to 2026-03-30 | ASTM D6007-22 small-chamber method |
| Report issued | 2026-03-31 | Report No. HJ-QAT-260457 |
Test Result
The sample tested was 18mm 13-ply birch (Birch) HWPW-VC, surface uncoated.
| Sample | Formaldehyde Emission |
|---|---|
| 260457-1 | 0.040 ppm |
| 260457-2 | 0.038 ppm |
| 260457-3 | 0.038 ppm |
| Average | 0.039 ppm |
Limit under 40 CFR Part 770 (EPA TSCA Title VI) & CARB 93120 Table 1 Phase 2 for HWPW-VC: 0.05 ppm
Result: 22% safety margin below regulatory limit.
AU/NZ reference point: plywood emission classes are defined in AS/NZS 2269, not the AS/NZS 1859 series — 1859 covers reconstituted panels (particleboard and MDF), which we don't build with. EWPAA's published comparison of the AS/NZS 2098.11 desiccator method against ASTM D6007 places the AS/NZS 2269 E0 class at a level comparable to the 0.05 ppm EPA hardwood plywood requirement, and Super E0 at the 0.04 ppm ULEF level. Our 0.039 ppm sits below both. This is a method-to-method comparison, not a substitute for direct testing — AS/NZS 2098.11 desiccator testing can be arranged for qualifying orders through CTI, issued in your name.

Other Supplier-Held Certifications
The above documents the plywood mill, which represents the highest-risk material in MJK's product line (formaldehyde emission from engineered wood). For solid wood components (beech tables, chairs, accents), supplier-held documentation is similarly available under NDA after supply agreement. MJK does not at this stage maintain its own FSC Chain-of-Custody certification — see Section 4 for our planned timeline.
Order-Triggered Testing via Accredited Laboratories
Supplier-held documentation tells you what the mill is approved to produce. Order-triggered testing tells you what was actually shipped to you. These are different evidentiary categories, and serious B2B buyers usually want both.
Why Order-Triggered Testing, Not Per-Product
Most factories of our size present "all products certified to [standard]" as a marketing claim. We do not, for three reasons:
- Per-product certification is rarely actually performed at the volume implied by such claims. The certificate often covers a single sample, not every variant in the product line.
- Material lots change over time. A certificate issued in 2023 says nothing reliable about a 2026 shipment.
- Order-triggered testing is more honest and more defensible in customs disputes, recall scenarios, and importer due diligence.
For these reasons, MJK's compliance posture is:
- We share what the mill currently holds (Section 2)
- We trigger third-party testing for qualifying orders when the buyer needs formal proof
- The test report is issued in the buyer's name, not MJK's
Standards Coverage Matrix
The following standards are available on an order-triggered basis via Centre Testing International (CTI) — a globally recognized testing organization with laboratories accredited by CNAS, CMA, and equivalents. Coverage spans US, EU, and AU/NZ regulatory regimes:
| Standard | Region | Scope |
|---|---|---|
| ASTM F963 | US | Toy safety, mechanical & flammability |
| CPSIA | US | Lead content, phthalates, third-party testing |
| 16 CFR 1303 | US | Lead in paint |
| 16 CFR 1307 | US | Prohibition of children's toys containing specified phthalates |
| TSCA Title VI | US | Formaldehyde emission, finished goods level |
| AS/NZS 4610 | AU/NZ | Furniture — School and educational (covers MJK's storage, shelves, lockers, tables, chairs) |
| AS/NZS 2098.11 | AU/NZ | Plywood — formaldehyde emission (desiccator method) — the test method behind the AS/NZS 2269 emission classes |
| AS/NZS 8124 | AU/NZ | Toys and children's product safety — available on request for toy-classified items |
Each shipment-specific report is issued in the buyer's name, valid for customs and importer-of-record purposes.

In an industry where most factory websites read like a list of every possible certification logo, what a supplier explicitly refuses to claim is often more informative than what they boast about. Below are the things MJK does not claim, and why each matters.
The Things We Will Not Tell You We Have
1.We do not hold our own Montessori manufacturer certification.
Montessori is a pedagogy, not a regulated manufacturing standard. We design products informed by Montessori principles, but we are not certified by AMI, AMS, or any other Montessori organization as a manufacturer. Anyone who tells you otherwise is misrepresenting how Montessori certification works.
2.We do not yet hold our own FSC Chain-of-Custody (CoC) certification.
Our plywood supplier holds FSC C141103 (Section 2). MJK’s own FSC-CoC is in planning for Q3–Q4 2026, scheduled after our first OEM order to justify the audit cost. Until then, we cannot label MJK-manufactured finished goods as “FSC certified” — only the input plywood is.
3.We do not hold CE or REACH certification.
Wooden children’s furniture exported to Australia and New Zealand does not require CE marking (CE is for European Economic Area products) or REACH registration (REACH applies to chemical substances, not finished wood furniture). We list these here so you don’t have to ask.
4.We do not perform per-product completion-tense certification.
All formal compliance testing is conducted on an order-triggered basis via CTI, with reports issued in the buyer’s name. See Section 3 for the mechanics.
5.We are not a “Best Seller in AU,” a “Customer Favourite,” or an “Award-Winning manufacturer.”
We have no such accolades to claim. We are a small-to-mid OEM operating from a 3,000 m² factory and looking to grow our AU/NZ wholesale relationships methodically. Anyone making such claims at our company size should be questioned.
6.We do not operate as a sourcing agent or trading broker.
All products on this website are manufactured in our own Xuzhou factory. If a product is outside our wood-based capability, we say so and decline — we do not subcontract to factories we don’t control.
7.We do not claim FSC-certified product status for our finished goods.
Only the input plywood is FSC-certified (supplier-held). Finished MJK goods are FSC-input but not CoC-certified output — see point #2.
8.Order-triggered testing in the buyer’s name applies to qualifying orders, not every order.
Smaller orders are supported by our rolling 12-month factory test report. The trigger threshold is subject to order size and project scope — disclosed in quotation.
Why Reverse Transparency Matters
If you have spent any time evaluating Chinese furniture suppliers, you have seen the pattern: a logo wall of certifications, most expired, most issued for samples that bear little relation to production, and almost none verifiable independently. The information asymmetry favors the supplier.
We believe the asymmetry should run the other way. Telling you what we do not have is the fastest way to earn trust on what we do have. Sections 2 and 3 of this page are the part that matters. Section 4 is the part that makes the rest credible.
Next Step
If MJK's compliance posture aligns with your sourcing standards, the next step is a quotation conversation. Standard turnaround on first contact is under 30 minutes during Beijing business hours, typically from Evan (founder, operating principal) directly.
