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 per shipment 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 per shipment 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:

Test Result

The sample tested was 18mm 13-ply birch (Birch) HWPW-VC, surface uncoated.

SampleFormaldehyde Emission
260457-10.040 ppm
260457-20.038 ppm
260457-30.038 ppm
Average0.039 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. Equivalent compliance level to AS/NZS 1859.1 E0 for the Australian/New Zealand market.

How to Independently Verify Mill No. ICTT-18073

  1. Visit CARB Composite Wood Products Program registry at ww2.arb.ca.gov/our-work/programs/composite-wood-products-airborne-toxic-control-measure
  2. Locate the Approved Third-Party Certifier (TPC) list for ICTT Corporation (TPC-43)
  3. Cross-reference Mill No. ICTT-18073 in the certified mills list

If MJK ever changes its primary plywood mill, this page will be updated within 30 days of the supply agreement effective date.

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.

Per-Shipment Testing via Accredited Laboratories

Supplier-held documentation tells you what the mill is approved to produce. Per-shipment testing tells you what was actually shipped to you. These are different evidentiary categories, and serious B2B buyers usually want both.

Why Per-Shipment, Not Per-Product

Most factories of our size present "all products certified to [standard]" as a marketing claim. We do not, for three reasons:

  1. 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.
  2. Material lots change over time. A certificate issued in 2023 says nothing reliable about a 2026 shipment.
  3. Per-shipment 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 per-shipment third-party testing 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 per-shipment 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:

StandardRegionScope
ASTM F963USToy safety, mechanical & flammability
CPSIAUSLead content, phthalates, third-party testing
16 CFR 1303USLead in paint
16 CFR 1307USProhibition of children's toys containing specified phthalates

What We Don't Claim

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 seven things MJK does not claim, and why each matters.

Seven 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 per-shipment, 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.

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.
