Amazon Hazmat Review: Why Your Listing Was Flagged and How to Clear It

The message usually arrives a few days after you create the FBA listing: the ASIN is blocked, Amazon wants a safety data sheet or an exemption sheet, and nobody on your team has heard of either. If the stock is already in a warehouse there is a deadline on it too. This is the Amazon hazmat review, and once you know what the dangerous goods team is looking for it is one of the more predictable parts of selling on Amazon.

This guide covers what triggers the review, how to choose between an SDS and an Amazon exemption sheet, the four tests Amazon applies to an SDS, how long it takes, what the result means for FBA and why documents get sent back.

What Amazon is checking, and why cosmetics law does not get you out of it

Amazon stores and ships millions of products, and some of them burn, leak, or are under pressure. To do that safely and within transport law (in the US, the DOT hazardous materials rules in 49 CFR, and internationally the IATA, ADR and IMDG rules), it needs to know which ASINs are dangerous goods. Amazon's dangerous goods identification guide says it plainly: the physical and chemical properties of the finished product decide whether it is a dangerous good, so there is no classification by product type, and Amazon asks for documents even when a product turns out not to be regulated.

Cosmetic brands often push back here, and the law is on their side up to a point. Finished cosmetics intended for the final user are exempt from the SDS rules in Article 2(6)(b) of REACH and from CLP classification under Article 1(5)(c) of CLP. In the US, cosmetics packaged for retail sale fall outside OSHA's Hazard Communication Standard. None of that matters to Amazon. It is not asking because chemicals law requires an SDS. It is asking because an 80% ethanol eau de parfum is a flammable liquid in a warehouse whether or not it is a cosmetic under Regulation (EC) No 1223/2009. Our guide to whether cosmetics need an SDS covers the legal side in detail; this one is about getting through Amazon.

What triggers an Amazon dangerous goods review

Amazon reviews each ASIN converted to FBA that looks like a possible dangerous good, and its main evidence is your own catalogue data: the title, bullets, description, attributes and images. On its review process page Amazon also mentions batteries named on the detail page or in buyer reviews. Its list of possible dangerous goods for beauty reads like a perfumer's stock list: spray deodorants, hairspray, hair dyes, perfume, self-tan, nail polish, shaving foams. Essential oils sit in the food section of the same list.

Two things catch sellers out. First, change the catalogue information later and Amazon may review the ASIN again, so a new title or new images can reopen a product you thought was settled. Second, a missing warning label proves nothing. Amazon notes that some dangerous goods, cosmetics included, carry no warning labels at all.

SDS or Amazon exemption sheet: the choice most sellers get wrong

Amazon accepts the exemption sheet for two categories only: battery and battery-powered products, and products without harmful chemicals. Send it for anything else and it will be rejected. The sheet is an Excel template you download from Manage dangerous goods classification; every red cell has to be completed, and it has to go back as an Excel file, not a PDF.

The phrase that matters is "without harmful chemicals". The template gives examples that rule it out (alcohol, isopropanol, acetone, hydroxides, sodium compounds, acids) and asks for an SDS for products such as essential oils. That excludes a lot of handmade cosmetics that are perfectly harmless in use. A lavender body butter will not set a warehouse alight, but an exemption sheet for it is likely to come back. For most fragranced products the SDS is the safer route, even when it ends up saying "not regulated".

Product	Document to send	Typical result
Alcohol-based perfume, body mist, aftershave	SDS	Class 3 flammable liquid (UN1266)
Aerosol deodorant, dry shampoo, hairspray	SDS	Class 2 aerosol (UN1950)
Nail polish and solvent-based remover	SDS	Usually Class 3 flammable liquid
Alcohol hand sanitiser	SDS	Class 3 flammable liquid
Essential oils and concentrated blends	SDS (Amazon's template rules out the exemption sheet)	Depends on flash point and environmental hazard
Reed diffuser	SDS	Depends on the solvent: alcohol or low-flash bases are Class 3, high-flash glycol bases often are not
Scented candle, wax melt	SDS for the finished product	Usually not regulated for transport; CLP labelling may still apply
Fragrance-free balm, butter or water-based lotion with no listed harmful chemicals	Exemption sheet may be accepted	Not regulated
The same balm or lotion with essential oils or fragrance	SDS	Usually not regulated, but the SDS is what proves it

The table shows typical outcomes, not guaranteed ones. The classification comes from the finished product's own data, mainly its flash point and composition.

Amazon SDS requirements: the four tests

Amazon's required information and documentation page sets out what a compliant SDS must do:

1. Be created or updated within the past five years. An undated SDS, or one from 2019, fails before anyone reads it.
2. Include current GHS/CLP hazard identification. Old-style risk phrases or a pre-GHS "MSDS" will not do.
3. Match the listing. The product name on the SDS must be the same as the title on the detail page, and the manufacturer or brand must match too.
4. Include all 16 standard sections. Not a one-page summary, a certificate of analysis or a test report.

The third test is where most sellers trip. "Lavender Body Oil 100 ml" on the SDS and "Calm Night Pillow and Body Oil with Lavender" on the listing look like two products to a reviewer. Make the SDS name match the listing, or change the listing.

The sections the reviewer leans on

• Section 1: product name and supplier, checked against the detail page.
• Section 2: GHS/CLP hazard classification, pictograms and statements.
• Section 3: composition, which has to make the classification believable. Seventy percent ethanol in section 3 and "not classified" in section 2 is a contradiction.
• Section 9: physical properties, above all the flash point. Under 49 CFR 173.120 a liquid with a flash point of 60 °C (140 °F) or below is a flammable liquid, and Amazon's listing form asks for the flash point in °C.
• Section 14: transport information: UN number, proper shipping name, class and packing group, or a clear statement that the product is not regulated. Amazon wants the UN number written as "UN1266", with no space.

A note for US brands. Under Appendix D of the OSHA standard, sections 12 to 15 are non-mandatory, so a US SDS written purely for OSHA can leave section 14 thin or blank. Amazon still wants all 16 sections, and for any liquid with alcohol or solvent section 14 is the one that decides the outcome. Make sure yours is filled in properly.

If you also sell in the EU or UK, the SDS for those markets follows Annex II of REACH and must be in the official language of the country where the product is supplied (Article 31). For candles, diffusers and other non-cosmetics that also means a CLP label and, in the EU, a poison centre notification with a UFI if the mixture is classified.

How to submit, and how long the review takes

Upload the document in Manage dangerous goods classification, using Upload document against the ASIN. Amazon says products with complete and correct information are classified within two business days, Monday to Friday, excluding public holidays. Submit on a Saturday and the clock starts on Monday.

That two-day figure is per attempt. A rejected document, or a request for more information, means another two business days after you resubmit, and so does every later upload. Three rounds of guesswork can cost you two weeks of sales.

Two more rules worth knowing:

• Stock already in a fulfilment centre. If Amazon flags a product that is already in its warehouse, it emails you, and you have 14 business days to supply documents. After that the inventory is disposed of at your expense.
• Bundles and kits. A gift set with a perfume, a body lotion and a shower gel needs an SDS for each chemical product in it, not one for the box.

Once you have uploaded, check the result with the Look up an ASIN tool before you build a shipment. Amazon warns that units sent before the classification is confirmed may have to be disposed of without reimbursement.

What the result means for Amazon FBA dangerous goods

• Not regulated. The product is stored and shipped like any other. Keep the document on file, because a later catalogue change can reopen the review.
• Regulated, but allowed. Amazon can take classes 2.1, 2.2, 3, 4.1, 5.1, 5.2, 6.1, 8 and 9 through FBA, but only in limited quantities and only for sellers in the FBA Dangerous Goods program. Amazon currently runs a waitlist for it, and adds sellers automatically when stock already in a fulfilment centre is reclassified. Until you are in, many brands fulfil their perfumes and aerosols themselves.
• Prohibited for FBA. Classes 1, 2.3, 4.2, 4.3, 6.2 and 7 (explosives, toxic gases, spontaneously combustible and water-reactive substances, infectious substances and radioactive material). Almost no cosmetics land here.

Why documents get sent back

• Wrong product. The fragrance supplier's SDS for the oil, uploaded for a finished candle or perfume. The name does not match and the hazards are for a different mixture.
• Name or brand mismatch. Even when it is your product, a different name from the detail page fails the third test.
• Out of date. Older than five years, or no date at all.
• Missing sections. Often a US SDS with sections 12 to 15 left out.
• Internal contradictions. A flash point of 21 °C in section 9 and "not regulated for transport" in section 14.
• Contradicting the listing. The SDS says no alcohol; the bullets say "with 80% organic alcohol".
• Wrong document type. An exemption sheet for a product that contains alcohol or essential oils, or a CPSR, test report or certificate where an SDS was asked for.

A worked example: one brand, four products

This is a composite of the kind of range we see most weeks, not a single client. A small fragrance brand converts four ASINs to FBA in the same afternoon, and all four are flagged.

• Eau de parfum, 50 ml, 80% ethanol. Flash point well below 60 °C. The SDS shows flammable liquid in section 2 and UN1266, perfumery products with flammable solvents, Class 3 in section 14. Amazon classifies it as a dangerous good. The brand joins the FBA Dangerous Goods waitlist and ships this one itself for now.
• Roll-on perfume oil, 10 ml, fragrance in fractionated coconut oil. No alcohol, and a measured flash point above 60 °C. The SDS states not regulated for transport in section 14, and it clears as not regulated. It still needed an SDS, because the listing says perfume.
• Reed diffuser, 100 ml. The first draft listing used the supplier's diffuser base SDS. Rejected: wrong product name. A finished-product SDS with the brand's own name, CLP classification for the fragrance load and a section 14 based on the base's flash point cleared it on the second attempt, two business days later.
• Lavender body butter. The brand sent an exemption sheet. Rejected, because the butter contains lavender essential oil. An SDS showing no transport classification cleared it.

Two of the four were rejected the first time, and both rejections were avoidable. Had the documents been ready before the listings went live, all four would have been classified in the first two-day window.

Disputing a classification

If you think Amazon has classified a product wrongly, its review page offers two routes: upload a new SDS or exemption sheet that supports your claim, or use Dispute classification in Manage dangerous goods classification. Either way, the document wins the argument, not the case note. If you believe your perfume oil is not a flammable liquid, the measured flash point in section 9 and a matching section 14 are your evidence. Resubmitting the same file gets the same answer, two business days later.

Before you list: a quick checklist

Classify before you list, not after the block. Write listings that describe the product honestly; a review with the right document is quick, and trying to dodge it only moves the problem to a worse moment. Keep one finished-product SDS per ASIN, named exactly as the listing, and diary its five-year renewal. Reformulate, change the fragrance or change the alcohol level, and the SDS has to change too.

If you sell across Amazon, Etsy and your own site, our overview of marketplace compliance documents shows which papers each platform asks for. For candles and wax melts, the CLP side is covered in our guide to the toxicological risk assessment for candles and wax melts.

Phoenix writes SDSs for Amazon US sellers and Amazon UK sellers, with section 14 completed for the way Amazon actually ships. If your range mixes cosmetics, perfumes and home fragrance and you are not sure which products need an SDS and which can go on an exemption sheet, a short regulatory consultation will sort them before you list.

Myths we hear

• Cosmetics are exempt from SDS rules, so Amazon cannot ask for one. The exemption is from the legal duty to supply an SDS under REACH. Amazon asks because it has to store and ship your product safely, and it can set its own conditions for using FBA.
• If there is no warning on the pack, it is not a dangerous good. Amazon says plainly that some dangerous goods, cosmetics among them, carry no warning labels at all. An 80% alcohol perfume is a flammable liquid whatever the box looks like.
• An exemption sheet is the quick option for any "natural" product. It is only accepted for battery products and products without harmful chemicals. A balm scented with essential oils falls outside it, and Amazon will reject the sheet.
• My fragrance supplier's SDS will do. That SDS describes the fragrance oil, not your finished candle, perfume or diffuser. The name will not match your listing and the hazards will be wrong.
• Leaving trigger words out of the listing avoids the review. Amazon reads images, bullets and even buyer reviews. A listing written to dodge the review is a misdescribed listing, and it usually gets caught after the stock has shipped.

What to do this week

1. List every ASIN you plan to send to FBA and mark anything with alcohol, propellant, essential oils, solvents or batteries.
2. For each one, decide: full SDS, or exemption sheet (only batteries and products with no harmful chemicals).
3. Get a finished-product SDS, dated within five years, with the product name and brand exactly as they appear on the detail page.
4. Check section 9 (flash point in °C) and section 14 (UN number, class, packing group) agree with each other and with section 2.
5. Upload in Manage dangerous goods classification, one document per product, and one SDS per item in a bundle or kit.
6. Check the result with the Look up an ASIN tool before you create the shipment.
7. Diary a review of every SDS before its fifth birthday, and redo it straight away after any reformulation.
