How to Create a CE Declaration of Conformity

If you are importing physical products into the European Economic Area (EEA), you cannot legally sell them without a CE Mark. However, many importers mistakenly believe that the CE Mark is simply a sticker you buy and slap onto a product box.

In reality, the CE Mark is a visible declaration of a much deeper legal process. The cornerstone of this process is the EU Declaration of Conformity (DoC).

The DoC is a legally binding document drafted and signed by the manufacturer (or the importer assuming the manufacturer's liability) stating that the product meets all essential health, safety, and environmental protection requirements of the applicable European directives. If a customs officer at an EU border, a distributor, or an online marketplace like Amazon requests this document and you cannot provide a valid, properly formatted copy, your shipments will be seized, and your listings will be suspended.

Here is the definitive, step-by-step guide to creating a legally compliant CE Declaration of Conformity.

B2B Vegan and Allergen Declarations

If you are manufacturing cosmetics, food products, dietary supplements, or even textiles, your commercial success depends entirely on securing shelf space with major retailers and listings on online marketplaces.

However, before a supermarket chain, specialty boutique, or pharmacy distributor signs a purchasing agreement, their procurement and quality assurance teams will send you a detailed compliance packet. Near the top of their list will be a mandatory request for a Vegan Declaration and an Allergen Declaration.

With consumers increasingly demanding transparency regarding ingredients, and with strict food allergen labeling laws globally, retailers cannot afford the massive liability of a mislabeled product. If a consumer suffers a severe allergic reaction due to an undeclared ingredient, or if a vegan product is found to contain animal-derived gelatin or animal testing traces, the retailer faces a PR nightmare and potential class-action lawsuits.

To protect their business, buyers require you to legally certify your product's ingredient purity. Here is how to write a legally robust, audit-ready B2B vegan and allergen declaration.

UKCA Declaration of Conformity: Complete UK Guide

In March 2026, the UK government published updated guidance reaffirming that CE marking remains accepted in Great Britain until December 2027, with UKCA becoming mandatory from January 2028. The Product Regulation and Metrology Act 2025 also introduced Fast-Track UKCA, allowing manufacturers to use EU conformity assessment procedures to apply the UKCA mark. Despite this flexibility, many manufacturers still struggle with the transition because the legal references are fundamentally different — UK Statutory Instruments instead of EU Directives.

Most manufacturers assume a UKCA Declaration of Conformity is just a CE DoC with the logo swapped. It is not. We help electronics and machinery clients transition from CE to UKCA on the Sustalium platform, and the UK statutory instrument mapping is consistently the part that trips teams up.

For goods placed on the market in Great Britain, the UKCA (UK Conformity Assessed) marking replaces the European CE Mark. The legal backbone is the UKCA Declaration of Conformity (DoC) — a formal legal document signed by the manufacturer stating the product complies with all relevant UK statutory instruments. If British Trading Standards audit your product, this is the first document they request.

Here is the step-by-step guide we use with our clients.

GPSR Compliance Checklist: EU Product Safety Rules

Amazon, Ebay, Vinted, and marketplace sellers are getting blocked daily because they lack a GPSR-compliant file for their products. On the Sustalium platform, the #1 question we get from new clients is: "What exactly do I need to document to stay compliant?"

The EU General Product Safety Regulation (GPSR — Regulation [EU] 2023/988) is now in full force, and it specifically targets e-commerce, third-country imports, and direct-to-consumer brands. Online marketplaces like Amazon, Zalando, eBay, Vinted, and Shopify now act as legal gatekeepers — if you cannot provide a verified compliance dossier for every SKU, your listings get pulled.

Here is the step-by-step checklist we use internally when onboarding sellers onto our platform.

In June 2026, German and French market surveillance authorities jointly flagged over 2,000 ASINs for missing Responsible Person data, and Amazon has begun sending final-notice compliance emails with 14-day deadlines before permanent ASIN removal. The message is clear: GPSR enforcement is no longer advisory.
