What to look for when buying American spice blends

What to take away

• Read the declared quantity, not the container. Tins and jars are designed to look larger than they are.
• Ingredient order tells you whether you are buying spice or salt.
• A bioengineered disclosure is a marketing label required by a standard. It is not a safety or quality statement.
• Packaging matters. Light and air degrade a blend, so a clear jar on a bright shelf is a worse buy than a tin.

Start with quantity and price per gram

Compare on price per gram, always. Two tins of the same height can hold quite different weights, especially across grind sizes, because a coarse blend takes more volume for the same mass.

The rules behind that printed quantity are updated regularly. NIST announced the 2025 editions of Handbooks 44, 130 and 133, noting changes across the scales section of Handbook 44 and updates to the uniform regulations in Handbook 130, and that these editions are moving to fully electronic formats. Handbook 130 carries the uniform packaging and labelling regulation that many states adopt, which is why the declaration on the back of a spice tin is consistent from state to state.

The five things to check on the shelf

• Declared net quantity, and the resulting price per gram.
• Ingredient order by weight, especially where salt and sugar sit.
• Whether ingredients are specific or hidden inside the word spices.
• Packaging type. Opaque, sealed and small beats clear, loose and large.
• Any date on the package, and whether it refers to packing or to best quality.

Bioengineered disclosure, read correctly

Some blends carry a bioengineered food disclosure. AMS explains in its information for consumers that retail products that are bioengineered or contain bioengineered ingredients say so on the label through words, a symbol, a scannable link or text message instructions, and that only foods meeting the agency's definition carry the disclosure. It also states plainly that the disclosure is a marketing label and conveys no information about health, safety or environmental attributes compared with non bioengineered counterparts, and that food from very small manufacturers and food served in restaurants is not required to bear it.

That last point matters for spice shoppers, because the absence of a disclosure on a small blender's tin tells you nothing either way.

Buy the size you will finish. This is the most reliable saving available in the spice aisle and the one shoppers most often get wrong. A large container bought at a lower price per gram is a false economy if the final third is dull by the time you reach it, and for most households that happens well within a year on ground blends.

Two questions worth emailing

Ask when the blend was mixed, and ask whether the spices were ground in house or bought pre-ground. Neither answer is on the label, both are known to the maker, and the willingness to answer separates a business that tracks its stock from one that does not.

Answer you get	What it suggests
A specific mixing month	Stock is rotated and recorded
Ground in house to order	Fresher aromatics, smaller runs
Bought pre-ground in bulk	Cheaper, and likely older
No answer at all	Reseller rather than blender

Common questions

Is a tin better than a jar? For light exclusion, yes. For seeing what you are buying, no. Buy small either way.

Does a best before date mean much? For dry blends it is a quality date. Aroma is the better test.

Should I avoid blends listing spices generically? Not automatically, but a specific list is worth paying a little more for.

Is bulk cheaper? Per gram yes, in practice often not, because the last third is usually stale before you reach it.
