Lavender grows almost anywhere. Bergamot does not.
That single difference explains most of what is worth saying about local versus imported materials in soap. Some plants are agreeable. They tolerate a range of soils and latitudes, and a maker on a coast in the west can grow a respectable crop within walking distance of the studio. Other plants are stubborn. They produce their best oil only in a narrow band of geography, and no amount of intention shortens the distance between that place and the bench where the soap is made.
What geography decides for you
Bergamot is the clearest case. The fruit grows commercially in usable quality almost nowhere outside a strip of the Calabrian coast in southern Italy, where the climate, the soil, and a century of cultivation produce an oil that plantings elsewhere have never matched. Frankincense comes from resin tapped from Boswellia trees in Oman, Somalia, and a few neighbouring regions. Sandalwood of any quality means India or Australia. Vetiver means Haiti or Java. These are not preferences. They are facts of agriculture.
For materials like these, “buy local” is not a principle a soap maker can honour. It is simply unavailable. The honest position is to source the best version of the material from wherever that version exists, and to accept that the place was decided long before anyone went looking.
The materials that genuinely could be local
The other half of the picture is more flexible than the slogan suggests in the opposite direction. Plenty of soap ingredients are now produced in many countries. Olive oil and sunflower oil are pressed across multiple continents. Shea butter, long associated with West Africa, is grown and processed in a widening range of regions. Lavender, rosemary, calendula, and many of the herbs and botanicals that find their way into a bar will grow in temperate gardens across the world.
For these materials, local sourcing is a real option, and often a reasonable one. A maker can grow lavender in their own region and still buy bergamot from Calabria. Both decisions can be correct at the same time. There is no contradiction in a bar that is partly grown down the road and partly shipped across a continent, only two materials, each sourced from where it happens to be best.
Why “local” runs out of usefulness as a rule
The trouble with local as a sourcing principle is that it tries to answer a question about quality and ethics by measuring distance. Distance is rarely the thing that matters most.
A locally grown oil produced with heavy irrigation, poor soil management, and exploited labour is not better than an imported one grown carefully and traded fairly. The questions that actually separate a good ingredient from a poor one are about cultivation method, harvesting practice, processing, and the conditions of the people doing the work. Where the field sits on a map is a weak proxy for any of these. This is the same problem that runs through most environmental shorthand, the label sounds decisive and tells you less than it promises. The same gap appears when soap is described as eco-friendly, a phrase that points in a good direction without committing to anything specific.
The same applies to materials that carry genuine ethical weight regardless of distance. Palm oil is the obvious case: where it comes from and how it is grown matters enormously, and “local” does nothing to resolve it. We have written about why palm oil resists an easy answer on its own terms.
The carbon argument, kept in proportion
There is a transport objection worth addressing directly, because it is often where the local case is made loudest.
Essential oils are used in soap at small fractions of the total weight. A few drops of bergamot scent an entire bar. The shipping carbon attributable to the oil in a single bar of soap is very small, far smaller than most people assume, and usually trivial next to the impact of how the plant was cultivated in the first place. Irrigation, land use, fertiliser, and processing energy almost always outweigh the freight. A material grown with care and shipped a long way frequently has a lighter footprint than one grown carelessly nearby.
The more meaningful environmental questions about a bar of soap sit elsewhere entirely, in how long the bar lasts, in what happens to it after it goes down the drain, and in what wraps it on the shelf. Transport distance is real, but it is rarely the lever that matters.
So the principle we work to is plain. Grow or source locally where the local version is genuinely the best. Buy from Calabria, Oman, or Java where it is not. Prioritise how a material is cultivated and who is paid to cultivate it. And accept that some materials, by their nature, have to travel.
