Complete guide on the legal requirements for reselling Amazon returns. We analyze applicable regulations, tax obligations, labeling, warranties, and seller responsibilities. Ideal for entrepreneurs buying liquidation lots at LotesOnline.es.

Is it legal to resell Amazon returns in Spain?

The short answer is yes, but with important nuances. Reselling products from Amazon returns or liquidation lots is a perfectly legal commercial activity, provided you meet a series of legal requirements established by Spanish and European regulations. The issue is not the product's origin, but how you market it.

Every year, Amazon returns millions of items to the market through channels like Amazon Warehouse Deals or pallet auctions. Many entrepreneurs buy these lots on platforms like LotesOnline.es to resell them on Wallapop, Milanuncios, Vinted, or even in physical stores. However, ignoring the regulations can turn a profitable business into a legal problem with the Tax Agency, Consumer Affairs, or even the Spanish Data Protection Agency.

In this article, we break down, step by step, everything you need to know to resell Amazon returns in compliance with the law. From VAT to warranties, including labeling and civil liability.

Applicable legal framework: which rules affect reselling?

When you buy a lot of Amazon returns to resell, you become a professional trader for legal purposes. The regulations that affect you are the same as those for any store, even if you sell occasionally on second-hand platforms.

1. General Law for the Defense of Consumers and Users (Royal Legislative Decree 1/2007)

This is the key regulation. It establishes that any product you sell must be safe, conform to the contract, and, if defective, the buyer has the right to repair, replacement, or refund. Even if you buy liquidation lots, you cannot sell products that are dangerous, non-functional, or that fail to meet minimum specifications.

2. Law on Guarantees in the Sale of Consumer Goods (amended by Royal Decree 7/2021)

Since 2022, warranty periods have been extended. If you sell as a professional:

  • Legal warranty of 3 years for new products (since January 1, 2022).
  • Warranty of 1 year for second-hand products, if expressly agreed.
  • Reversal of the burden of proof during the first year: if the product fails, it is presumed the defect existed when you sold it.

Important: If you sell a lot of Amazon returns as "new" but it has a dent or is missing an accessory, you could be committing misleading advertising.

3. Retail Trade Regulation Law (Law 7/1996)

It regulates aspects such as opening hours, sales, and, above all, pre-contractual information. You must clearly inform the buyer that the product may be a return, that it is refurbished, or that it has minor aesthetic defects.

Tax obligations: the Tax Agency does not forgive

One of the most common mistakes among novice resellers is thinking that selling "occasionally" on platforms like Wallapop is not taxable. Serious mistake. If you buy liquidation lots for profit, you are carrying out an economic activity.

Registration with the Tax Agency and Social Security

  • You must register in the Business Census (form 036 or 037).
  • The most common IAE code is 611.5 (Retail trade of used products) or 659.9 (Retail trade of unspecified products).
  • If you exceed the SMI (around €1,080/month in 2025), you must register in the Special Regime for Self-Employed Workers (RETA).
  • If you sell occasionally (less than €1,080/month and without regularity), you could opt for the flat-rate VAT regime (if you sell to final consumers) or file form 303 quarterly.

VAT on reselling returns

The VAT treatment depends on whether the product is new or used:

  • New products (never opened, in original packaging): you apply standard VAT (21%) or reduced VAT (10% or 4% depending on the product type).
  • Used or refurbished products: you can apply the Special Regime for Used Goods (REBU). In this case, VAT is only calculated on the profit margin, not on the total sale price. This is very advantageous if you buy liquidation lots at low cost.

Practical example: You buy a lot of 10 refurbished phones for €500. You sell one for €100. Under the general regime, VAT would be €21. Under REBU, you calculate the margin: €100 - €50 (proportional cost) = €50 margin; VAT would be 21% of €50 = €10.50. You save half.

Invoicing obligation

  • If you sell to a final consumer, you are not obliged to issue an invoice (unless the buyer requests it).
  • If you sell to another professional (e.g., a store), you must issue an invoice with all tax details.
  • Since 2024, digital platforms (Wallapop, Vinted, etc.) are required to report sales exceeding €2,000 annually or 30 transactions to the Tax Agency. Do not forget this.

Labeling, safety, and product liability

This is where many resellers commit violations without knowing it. European product safety regulations (Regulation 2023/988, formerly Directive 2001/95) require that any product you place on the market must be safe.

Labeling requirements

Depending on the type of product, you may need:

  • Electrical and electronic products: they must bear the CE mark, the recycling symbol (WEEE), and, if applicable, safety instructions in Spanish.
  • Toys: they must have the CE mark, recommended age, safety warnings, and the manufacturer's or importer's name.
  • Textiles: composition, size, washing instructions, and country of origin.
  • Cosmetics: ingredient list, expiration date (PAO), and responsible party details.

Tip: If you buy a lot of Amazon returns, many products already come labeled. But if the packaging is damaged or the label is missing, you cannot sell it as new. You must label it as "refurbished" or "second-hand" and add the necessary warnings.

Civil liability

As a professional seller, you are responsible for damages caused by a defective product. For example, if you sell a charger that does not comply with regulations and causes a fire, you can be sued for damages. To protect yourself, it is advisable to take out civil liability insurance specific to your activity.

Data protection and resale platforms

If you sell through platforms like Wallapop, Vinted, or eBay, you must comply with the General Data Protection Regulation (GDPR). Although you do not collect data on a massive scale, you do manage names, addresses, and payment details.

  • Do not share buyers' personal data.
  • Delete any personal information that may come with the products (e.g., hard drives with previous data).
  • If you sell electronic devices, always erase the previous user's data before reselling them. Amazon does not always do this.

Practical cases: what you can and cannot do

To make it clearer, let's look at three real scenarios:

Case 1: Selling a used book with underlines

  • Legal: Yes, as long as you describe it as "used" or "with annotations."
  • Requirement: You cannot sell it as "new" or hide the defects.

Case 2: Selling a phone charger without CE marking

  • Legal: No. Even if you buy it in a liquidation lot, if it does not have the CE mark, you cannot market it in the EU. You could face fines of up to €600,000.

Case 3: Selling an expired perfume

  • Legal: No. Cosmetics have an expiration date or PAO. Selling them expired is illegal and dangerous.

Checklist for reselling Amazon returns without legal issues

Before launching your listing, review this list:

  • Are you registered with the Tax Agency as self-employed or a business?
  • Have you chosen the appropriate VAT regime (general or REBU)?
  • Is the product safe and does it have the CE mark if required?
  • Is the labeling complete and in Spanish?
  • Have you clearly described the product's condition (new, refurbished, used)?
  • Have you removed personal data from electronic devices?
  • Do you have civil liability insurance?
  • Do you know the warranty periods you must offer?

Conclusion: sell smart and comply with the law

Reselling Amazon returns is a scalable and profitable business, but it is not a legal gray area. Consumer authorities and the Tax Agency are increasingly attentive to second-hand platforms and professional resellers. Ignoring the regulations can cost you fines, seizures, or even criminal problems if you sell dangerous products.

The key is to professionalize yourself: register, keep clear accounting, label correctly, and offer warranties. This way, you can scale your business without surprises.
