Every answer on this page comes from documents Handcraft Blends posts on its own product pages, read on 4 November 2026. We didn't test the oils, and a document posted by a brand is the brand's claim, so each one is named for what it is.
A Handcraft Blends product page can carry up to three files, and they prove different things.
The GC/MS report comes from a lab. It lists the compounds found in a sample of the oil, which is how adulteration with cheaper oils or synthetics usually shows up. Handcraft Blends files these as GC-FID/MS reports.
The Product Quality and Origin Declaration is written by Handcraft LLC itself. Each one we read is dated 17 December 2025 and gives the botanical name, extraction method and country of origin. It states the oil is 100% pure, undiluted, free of synthetic additives, non-GMO and vegan. The brand says this is "to the best of our knowledge based on information from our suppliers", and its own disclaimer adds that the document represents general quality and "is not strictly lot-specific".
The safety data sheet covers handling and hazards. It says nothing about purity.
Botanical name, origin and method are as written in each oil's quality declaration. The last column says whether a GC/MS report is posted on the product page and what its file name says about the batch.
| Oil | Plant and origin, per the declaration | Method | GC/MS report posted |
|---|---|---|---|
| Lavender | Lavandula hybrida grosso (lavandin), France | Steam distilled | Yes, titled Lavandin Oil, code LAVN0525 |
| Tea tree | Melaleuca alternifolia, Australia | Steam distilled | Yes, code TTRE0525 |
| Eucalyptus | Eucalyptus globulus, China | Steam distilled | Yes, code EUCL0525 |
| Peppermint | Mentha arvensis, India | Steam distilled | Yes, lot 250122142, dated 03/2027 |
| Rosemary | Rosmarinus officinalis, Spain | Steam distilled | Yes, code ROSE0525 |
| Cedarwood | Cedrus deodara, India | Steam distilled | Yes, code CDRW0525 |
| Ylang ylang | Cananga odorata macrophylla, Madagascar | Steam distilled | Yes, code YLAN0525 |
| Lemon | Citrus limonum, Mexico | Cold pressed | Yes, lot 250110218, dated 03/2027 |
| Bergamot | Citrus aurantium bergamia, Italy | Cold pressed | Yes, code BRGM0525 |
| Frankincense | Boswellia serrata, India | Steam distilled | No report posted |
| Clove leaf | Eugenia caryophyllus, Indonesia | Steam distilled | No report posted |
Seven of the nine report file names carry a code ending in 0525 rather than a lot number. Peppermint and lemon carry a lot number and the date 03/2027. The product pages don't say which lot is in the bottles shipping now.
None of the carrier oils we read has a GC/MS composition report or a quality declaration posted.
| Oil | Documents posted |
|---|---|
| Organic castor | Phthalates report from Applied Technical Services, 6 January 2026, and a safety data sheet |
| Fractionated coconut | Safety data sheet only |
| Sweet almond | Safety data sheet only |
| Organic jojoba | Safety data sheet only |
| Organic rosehip | Safety data sheet only |
| Grapeseed | No documents posted |
| Avocado | No documents posted |
The castor oil report is a phthalate test. Applied Technical Services used GC/MS to look for 14 phthalates in a bottle of the organic castor oil and found none above 5 ppm. That checks for plastic-related contamination. It doesn't show what the oil itself is made of.
Every product page we read, carrier oils included, shows a "GC/MS TESTED" badge. Most pages also have an Independent lab reports panel that says every batch is tested by a third-party lab before it ships, followed by "These are the reports on file for this product." On the frankincense, clove leaf, fractionated coconut, sweet almond, jojoba and rosehip pages, the files under that sentence are a declaration or a safety data sheet, not a lab report. The grapeseed and avocado pages carry the badge and no documents at all.
The brand may well test those oils. The pages just don't show it, so for those products the testing claim is one you have to take on trust.
The label says Lavender Essential Oil. The declaration gives Lavandula hybrida grosso from France, and the GC/MS report is titled Lavandin Oil. Lavandin is a hybrid, not the Lavandula angustifolia most lavender research uses. More in our lavender review.
The declaration gives Mentha arvensis from India. That is a different species from Mentha x piperita, the plant most recipes and studies mean by peppermint. If a source tells you to use peppermint for a specific purpose, check which species it tested.
The declaration gives Boswellia serrata from India. Guides to frankincense often describe Boswellia sacra or Boswellia carterii instead, so what a guide says about one species may not hold for this oil. This is also one of the two essential oils with no GC/MS report posted.
For the nine essential oils with a report, you can open the lab result and see what was found. It's still one report per oil, and the declarations say they aren't tied to a lot, so neither document is proof about the bottle you receive. For frankincense, clove leaf and every carrier oil except castor, the pages carry the testing claim without a report behind it. Whatever you buy, read the botanical name on the label before the common name.
The brand says so in writing. Each essential oil we read has a Product Quality and Origin Declaration from Handcraft LLC, dated 17 December 2025, stating the oil is 100% pure, undiluted and free of synthetic additives. The declaration is the brand's own statement, based on what its suppliers tell it, and it says it is not strictly lot-specific. For nine of the eleven essential oils we read, a third-party GC/MS report is also posted; frankincense and clove leaf have none.
Nine of the eleven essential oils we read have a GC/MS report posted on the product page, each from the same lab batch series. Frankincense and clove leaf have a quality declaration but no GC/MS report. The carrier oils we read have no GC/MS composition report; organic castor oil has a lab report for phthalates only.
The bottle says Peppermint Essential Oil. The brand's own quality declaration gives the botanical name as Mentha arvensis from India, which is a different species from Mentha x piperita, the plant most recipes and studies mean by peppermint. If you need piperita, look for that name on the label.
Not from what the product pages show. Each page posts one report per oil. Two report file names carry a lot number, the rest carry a batch code. We found no way to look up a report by the number on your bottle, so if you need it, ask the brand with your lot number.
