01 / Factory & textile credentials

Three credentials.
Different purposes.

Textile certification, organic production scope and a social audit each tell you something different about your manufacturing partner.

Textile certification

OEKO-TEX®
STANDARD 100

Textiles tested for harmful substances.

Our factory holds STANDARD 100 certification for the knitted socks and tights listed in its scope.

We confirm whether your chosen materials, grip application and finishing are covered before describing a finished sock as certified.

Scope & certificate details

Licence: GOTS-BVCN3609

GOTS Version 7.0. The product appendix lists socks, hosiery and baby accessories made from specified organic-cotton blends. The certificate runs from 8 May 2026 to 7 May 2027.

A scope certificate describes the factory’s approved activities. A matching transaction certificate is required to establish the GOTS status of delivered goods. We review the requirements for your design before you order.

Full monitoring by ALGI HOLDING COMPANY LLC. The report lists an expiry date of 13 July 2027.

This is a social audit of the factory, separate from product certification. Ask us about the audit information relevant to your sourcing requirements.

Certification applies to the scope stated in each document. We review coverage for your chosen sock specification.

02 / Grip material testing

The grip matters,
too.

Supplier reports cover specific silicone and PVC samples. We check material references against your order before sharing the relevant documentation.

01

Silicone
grip material

Liquid silicone rubber
Sample: AS8351(A/B)

Laboratory: SGSReport date: 20 May 2026

SVHC screening and selected chemical tests

The supplied reports cover REACH SVHC screening, RoHS-listed substances, selected California Proposition 65 chemical criteria and halogen testing.

See the testing scope

SVHC screening: Report SZXPC26002965604 screened 253 substances on the candidate list dated 4 February 2026, plus one potential SVHC. The report records results at or below 0.1% by weight for the submitted sample.

Other chemical tests: Report SZXPC26002965602 covers the stated RoHS substance limits, selected lead, cadmium and phthalate criteria associated with California Proposition 65, and halogen measurements.

The chemical-test report is specific to the submitted material sample and stated criteria. It does not establish complete regulatory compliance for a finished pair of socks.

02

PVC
grip material

Supplier-submitted PVC sample
Purple-brown adhesive

Laboratory: SGSReport date: 19 June 2025

Selected phthalate testing

The supplied PVC report records conformity with the specified phthalate criteria under REACH Annex XVII, entries 51 and 52.

See the testing scope

Report: NGBHL25003780801

The tested phthalates were DBP, BBP, DEHP, DIBP, DINP, DNOP and DIDP. Results were below the report’s stated detection limits for the submitted sample.

This report covers the selected phthalate tests. The material and testing requirements for your order are confirmed against your design and destination market.

Material test reports describe the samples tested on the dates shown. Your yarns, colours, grip formulation and finishing determine which documents apply.

03 / Before you order

A few useful
answers.

Have a specific standard in mind?
Tell us at the start of your project.

Are all custom grip socks covered by the same certification?

Coverage depends on the yarns, grip material, finishing and manufacturing specification. We check the relevant scope for your chosen design before confirming a certification claim.

Can I request GOTS documentation for an order?

Yes. Tell us you need a GOTS order before sampling. We’ll review the proposed materials and production requirements. The factory’s scope certificate alone does not certify a delivery; the goods need a matching transaction certificate.

How can I review the certificates and test reports?

Send us your sock style, destination market and the documents you need. Our team reviews your enquiry and shares the applicable documentation directly.
