EXPERIENCE
I am Tzu-Ting Wang. I spent ten years at Amazon's European headquarters across product, finance, and compliance risk, leading marketplace compliance work across nine European marketplaces. In my final role I advised Amazon's European board members on risk strategy.
Before Amazon I advised large global companies on risk and tax at Deloitte and KPMG. I bring 15+ years across the advisory and operating sides. My education includes an MBA from IE Business School and study at Yale University. I work in English and Chinese from Luxembourg.
QUESTIONS I GET ASKED
These general starting points help frame the questions. Your products, markets, and channels determine the specific answer.
The DSA requires marketplaces that let consumers contract with traders to collect specified trader details, make best efforts to verify them, design interfaces so traders can provide required product information, and notify affected buyers when they learn that an illegal product was sold. Very large platforms can face added risk-management duties.
For an operator, these duties become product decisions: required fields, listing blocks, exception reviews, buyer notices, and evidence retention.
The General Product Safety Regulation has applied since 13 December 2024. It covers non-food consumer products and supplements sector-specific rules where they do not cover a risk. A product in scope needs an EU-established responsible economic operator, which can be a manufacturer, importer, authorised representative, or fulfilment service provider depending on the supply chain.
Marketplaces also need a Safety Gate contact point and processes for authority orders about dangerous products.
EPR obligations are country- and product-stream specific. They depend on the goods, whether the national rule treats you as the producer, and where you first make them available. Electrical equipment, batteries, and packaging have separate schemes.
A country-by-product matrix is a practical starting point before choosing markets or channels.

The One Stop Shop can let a business report eligible cross-border consumer sales through one EU member state. Holding stock in another country will commonly create a local registration requirement there. Eligible low-value imports can use the Import One Stop Shop.
The answer follows the supply chain: where the business is established, where stock is held, where goods enter the EU, and who is treated as the supplier.
Responsibility depends on the rule and the role the marketplace performs. Under the DSA, the conditional liability exemption does not apply under consumer protection law when the presentation would lead an average consumer to believe the platform, or a trader under its control, supplied the product.
The revised Product Liability Directive applies similar distributor rules to some platforms for products placed on the market after 9 December 2026. Separate DSA and GPSR duties can apply even when the marketplace is not the seller.

Since 1 July 2026, the EU no longer grants customs duty relief to e-commerce consignments worth no more than €150 that are sent from outside the EU directly to consumers. An interim €3 customs duty applies for each tariff item category in a qualifying parcel until 1 July 2028, unless extended. A separate handling fee is also planned.
Sellers should recheck landed cost, tariff classification, fulfilment location, and pricing.
I connect specialist advice to the business decisions, product changes, responsibilities, controls, and sequence of work. When a legal opinion, tax filing, product test, certification, or local registration is needed, I help define the question and coordinate the right specialist.
Send me your goal, the European markets in scope, and the decision that needs to move. I will review the situation and suggest the most useful next step.
