GOTS certifies how a pad is made, OEKO-TEX tests what it contains, FDA registers the factory. Decode the marks on non-toxic pads.
The marks that matter on non-toxic sanitary pads are GOTS (supply-chain organic), OEKO-TEX Standard 100 (finished-product testing) and FDA establishment registration. USDA Organic and OCS cover less. Read the tier, not just the logo.
You want non-toxic sanitary pads and the shelf answers with a wall of logos. GOTS. OEKO-TEX. USDA. OCS. They are not interchangeable. Some are supply-chain audits; some test the finished pad; some only certify the cotton and say nothing about the glue. Here is the decoder.
GOTS — the supply-chain gold standard
GOTS (Global Organic Textile Standard) covers the whole chain: fibre, processing, bleaching, labour and wastewater GOTS official site. A GOTS pad means the cotton was grown without synthetic pesticides, bleached without chlorine, and made without toxic heavy metals or aromatic solvents. It has two tiers: "Organic" (≥95% certified organic fibre) and "Made with Organic" (≥70%). For truly non-toxic sanitary pads, you want the higher tier.
OEKO-TEX Standard 100 — the finished-product test
OEKO-TEX Standard 100 is a product-level test, not a farming standard OEKO-TEX official site. It screens the finished pad for 100+ substances — formaldehyde, heavy metals, pesticides, chlorinated phenols, phthalates. It is renewed yearly with unannounced factory audits. The catch: it does not prove the cotton was organic. A pad can be OEKO-TEX certified and still use conventional cotton. Pair it with GOTS for the full story.
FDA — registration, not approval
The FDA does not "approve" a pad the way it approves a drug FDA site. What it registers is the establishment — the factory — and it expects Good Manufacturing Practice. A serious non-toxic sanitary pads maker shows the establishment registration number, not a badge that says "FDA Approved." For brands, this is the line that lets product land in the US.
| Certification | What it proves | What it does NOT prove |
|---|---|---|
| GOTS | Organic fibre + clean processing end-to-end | Nothing about non-textile additives beyond scope |
| OEKO-TEX 100 | Finished pad free of 100+ harmful substances | That the cotton was organically farmed |
| USDA Organic | The cotton was organically grown | Clean adhesives, dyes or processing |
| OCS | Verified organic fibre content | Any restriction on chemical processing |
Two questions that expose greenwashing
Ask any supplier: "Is the whole product GOTS-certified, or just the cotton?" and "Can you show a batch-level OEKO-TEX certificate for this SKU?" If the answer hedges, walk away. The pad-ingredients guide explains why the whole product matters, and the OEM sourcing guide covers what to audit at the factory.
Frequently asked questions
Is GOTS better than OEKO-TEX?
They measure different things. GOTS certifies how the product is made; OEKO-TEX tests what the finished pad contains. Best pads carry both.
Does USDA Organic mean non-toxic?
Only for the cotton. The pad can still use synthetic adhesives and ECF-bleached pulp. It is a starting point, not a full guarantee.
What is OCS for?
OCS verifies organic fibre content only. A pad can be OCS-certified yet use chlorine-bleached SAP and petrochemical glue.
Why does FDA registration matter for export?
US-bound menstrual products need an FDA-registered establishment and GMP. Without it, customs becomes a wall.
