Every buyer asks the same four questions before placing a packaging order: Can you meet quality standards? Are your materials traceable? Will my product pass customs? Are you authorized to produce for my brand? Our certifications exist to answer those questions with documentation instead of promises.
Why certifications matter more than a sales pitch
In custom packaging, verbal guarantees do not survive a customs inspection or a retail audit. Certifications are third-party proof that a factory’s processes, materials and environmental controls meet recognized standards. For buyers selling into regulated markets like the EU, US or Japan, they are often the difference between smooth delivery and a seized shipment.
Here is how our key certifications map to buyer concerns:
| Certification | What it proves | Buyer benefit |
|---|---|---|
| ISO 9001:2015 | Quality management system | Consistent output, documented QC, traceable defects |
| FSC Chain of Custody | Responsibly sourced paper | FSC-labelled retail packaging, sustainability claims |
| CE-RoHS compliance | No restricted substances | Electronics and toy packaging can enter the EU legally |
| Disney authorization | Licensed brand production | Eligible for Disney-licensed product packaging |
ISO 9001:2015: the operational backbone
We passed ISO 9001:2015 Quality Management System certification between 2022 and 2024. This is not a one-time badge; it requires annual surveillance audits.
What changed on our factory floor after certification:
-
Incoming material inspection: Every paper lot is checked for GSM, caliper and surface tension before entering production.
-
In-process checks: Color bars are pulled every 500 sheets during offset runs.
-
Final inspection: AQL sampling is applied to finished goods before carton packing.
-
Document retention: Production records are kept for at least two years for traceability.

FSC Chain of Custody: proving paper origin
On 23 July 2025, we received FSC Chain of Custody (CoC) certification. This is critical for buyers who need to print the FSC logo on retail packaging or make sustainability claims to consumers.
FSC CoC means we can:
-
Purchase FSC-certified paper from accredited suppliers.
-
Separate FSC and non-FSC materials during production.
-
Issue FSC transaction certificates for eligible orders.
If your brand sells in Europe or North America and your marketing mentions “responsible forestry,” FSC certification is usually mandatory. Without it, your retailer or distributor may reject the goods.

CE-RoHS: the electronics and toy packaging passport
On 29 October 2024, we obtained CE-RoHS Directive Compliance Certificate and the matching RoHS Environmental Test Report. These are essential for packaging that touches electronics, toys and children’s products sold in the European Union.
RoHS restricts substances like lead, mercury, cadmium and hexavalent chromium in packaging materials. Our compliance means:
-
Inks and coatings meet EU substance limits.
-
Test reports can be provided per material batch if required.
-
Packaging will not block CE-marked product imports.

Disney authorization: licensed brand production
In 2021, we received Disney authorization, allowing us to produce packaging for Disney-licensed products. This is not a generic quality certificate; it means our factory passed Disney’s social compliance and production-capability audit.
Disney authorization requires:
-
Acceptable working conditions and labor practices.
-
Adequate production capacity and quality control.
-
Secure handling of licensed artwork and brand assets.
For buyers holding Disney, Marvel, Star Wars or other licensed product lines, this authorization removes a major supplier-qualification hurdle.

How buyers can verify our certificates
We encourage every buyer to verify documentation independently. Here is how:
- ISO 9001 certificate: Ask for certificate number 19819QI4013R1S and check with the issuing certification body.
- FSC CoC: Request the FSC license code and verify it on the FSC website.
- RoHS reports: Cross-check test dates and material scope against your product requirements.
- Disney authorization: Confirm the authorization letter covers your product category and region.
What this means for your next order
When you work with a certified factory, you are not just buying boxes. You are buying:
-
Lower audit risk: Retailers and customs see recognized standards.
-
Faster onboarding: Large brands accept certified suppliers faster.
-
Market access: FSC and RoHS open doors that uncertified factories cannot enter.
If your packaging needs to meet specific compliance requirements, tell us during quoting. We can route your order through the correct material and process flow from day one.
