How essential oils reach an export carton
Essential oils are taken from plant material by steam distillation or, for citrus peel, by cold pressing. Solvent-extracted absolutes and concretes are a different product, and should not be sold as essential oils. Distillation often happens close to the crop, in small units. The oil is then sold on to traders and exporters who bulk it, sometimes redistil or standardise it, and fill it into drums or retail bottles. The company on your invoice is often not the distiller.
That chain creates the main risks: an oil blended down with a cheaper oil or a synthetic, a lot made of several distillations under one batch code, oxidation from half-empty drums, and retail bottles filled from a different lot than the one the certificate of analysis describes. None of these can be seen by eye. What the inspector controls is that the containers, codes, labels and paperwork line up, and that the lab sample really comes from the shipped lot.
Cosmetic, aromatherapy oil or raw material: which rules apply
The same oil falls under different rules depending on how it is sold. Settle this in the specification before the labels are printed.
| Sold as | EU | US |
|---|---|---|
| Bulk raw material to a manufacturer | A substance under REACH and CLP: safety data sheet, CLP label on the drum, REACH registration by the EU importer or an only representative from 1 tonne a year | Industrial chemical paperwork; dangerous-goods rules for transport |
| Retail oil for diffusers or household use | CLP label in the local language, with child-resistant closure and tactile warning where the classification requires | FHSA cautionary labelling if hazardous; child-resistant packaging under the PPPA where it applies |
| Retail oil for skin, bath or massage | A cosmetic under Regulation 1223/2009. CLP excludes cosmetics in the finished state for the final user | A cosmetic under MoCRA; a drug if it claims to help sleep, relieve pain or treat a condition |
CLP requires child-resistant fastenings on packs sold to the public when the oil is classified for acute toxicity categories 1 to 3, STOT category 1, skin corrosion category 1 or aspiration hazard. Many oils rich in terpenes carry the aspiration hazard (H304) on their safety data sheet. Tactile warnings cover a wider list, including aspiration hazard, skin corrosion, acute toxicity and flammable liquids of categories 1 and 2. In the US, 16 CFR 1700.14 requires special packaging for liquid preparations with more than 5% methyl salicylate, the main component of wintergreen oil, and for some low-viscosity products with 10% or more hydrocarbons. Your compliance adviser decides which apply; the inspector checks the result on the goods.
What we check on essential oils
| Check | How it is checked | What fails |
|---|---|---|
| Drum condition and seals | Bungs, tamper seals and liners checked; drum seams and base inspected | Weeping seams, rust, dented chimes, seals broken or missing |
| Net weight | Drums and sampled bottles weighed on a calibrated scale, net of tare | Short weight against the packing list or label |
| Batch traceability | Batch on each drum and bottle against the certificate of analysis and packing list | Several codes in one lot without a record, codes that match no certificate |
| Hazard labels | Pictograms, signal word, hazard and precautionary statements, supplier and UFI where required, read against the SDS | Pictogram or H304 statement missing, label not in the destination language |
| Closures | Closure type against the certified child-resistant model; dropper insert fitted; tactile warning present where required | Plain cap on an oil that needs a child-resistant one; insert missing |
| Appearance and odour | Colour, clarity and odour against the retained sample | Cloudy oil, water layer, sediment, odour clearly off the sample |
| Dangerous-goods marks | UN number, proper shipping name, class label and UN packaging code against the forwarder's instructions | Missing marks, packaging without a UN specification mark |
| Organic paperwork | Certificate and transaction documents against the lot, quantity and certifier | Certifier not accredited for the target market, quantities that do not match |
Common essential oil defects and how they are classed
| Defect | Typical cause | Class |
|---|---|---|
| GC profile outside the specification, or a marker of adulteration | Oil cut with a cheaper oil or a synthetic | Critical |
| Child-resistant closure missing where required | Generic caps used for all oils | Critical |
| Hazard pictogram or statement missing | Label not updated from the SDS | Critical |
| Leaking drum or bottle | Bung not torqued, liner missing, damaged seam | Major |
| Short weight | Filling by volume with a temperature change | Major |
| Lot made of untraced batches | Trader bulking several distillations | Major |
| Smudged or lifting label | Label stock not resistant to the oil | Minor |
Your defect list decides the final class.
Dangerous goods and organic claims
Transport. A liquid with a flash point of 60 °C or below, closed cup, is a Class 3 flammable liquid. Packing group II covers flash points below 23 °C and group III covers 23 to 60 °C. Many essential oils fall in these bands. The UN Model Regulations now use UN 1197, "extracts, liquid, for flavour or aroma", which replaced the older UN 1169 entry for aromatic extracts. Some oils also carry the environmentally hazardous substance mark. Your forwarder decides the entry; the inspector checks that drums and cartons carry the marks and UN-specification packaging it asked for.
Organic. The USDA ended its organic recognition arrangement with India in January 2021, so oils sold as organic in the US must be certified by a USDA-accredited certifying agent, and each shipment needs an NOP Import Certificate. Indian rules for organic exports apply as well. The inspector checks that the certificate names the same product, lot and quantity as the cartons; it does not test whether the oil is organic.
Samples for GC or GC-MS, and for allergens where the oil is sold as a cosmetic, go to an accredited lab through lab testing coordination.
Packing and your purchase order
Oils oxidise with air, light and heat. Bulk drums should be full or blanketed with nitrogen if you specify it, and stored out of the sun; retail bottles should be amber or opaque glass. The inspector checks drum headspace where accessible, upright packing with dividers for glass, absorbent material where your plan asks for it, and that sealed drums are not reopened after the inspection.
