Lemons & Limes

Fresh lemon and lime trade begins by separating species, variety and grade—not treating all acid citrus as interchangeable. The current USDA lemon standard defines U.S. No. 1, U.S. Export No. 1, U.S. Combination and U.S. No. 2 and adds a measurable seedless claim. USDA lime grades are for Persian limes and attach firmness, form, surface texture, colour, juice content and defect tolerances. A comparable lot identifies lemon or lime, botanical and commercial variety, mature state, grade, colour or turning status, seedless claim and sample result where applicable, juice-content result where required, count and diameter distribution, shape, skin and internal-condition findings, origin and harvest, packer, package and net weight, treatment and cold chain, residue and plant-health evidence, quantity, currency, Incoterm, destination, delivery window and information vintage.

The figures below are current U.S. grading and marketing requirements from USDA Agricultural Marketing Service. The lemon standard took effect May 13, 2026; the lime grade index covers Persian limes. These requirements define product, grade, colour, condition, packing and claim boundaries. They do not establish current availability, certify a shipment, apply one species' specification to another, or provide a live delivered price.

Lemons and limes are separate trade identities

Lemons and Persian limes differ in grade language, colour expectations, maturity evidence, juice-content rules and buyer use. USDA lemon grades include U.S. No. 1, U.S. Export No. 1, U.S. Combination and U.S. No. 2. USDA Persian-lime grades use U.S. No. 1, U.S. Combination and U.S. No. 2 with Mixed Color and Turning designations where applicable. Atlas preserves species, variety and exact grade rather than applying one citrus specification to the other.

The 2026 seedless-lemon rule is a measurable claim

Under the USDA lemon standard effective May 13, 2026, a lot marked seedless may have no more than six fruit containing seeds in a 100-count composite sample, regardless of the number or development of the seeds in each fruit. At least 95 percent of containers, including consumer units, must be legibly marked seedless when the claim is used. Atlas retains the sample size, result and marking evidence with the claim.

Persian-lime colour and juice content belong with condition

The USDA lime standard attaches its grades to Persian limes. U.S. No. 1 fruit needs good green colour over at least three-fourths of the surface, while U.S. No. 2 uses at least one-half. The standard also sets a minimum juice content of 42 percent by volume or weight and grade-specific limits for decay, stylar-end breakdown, unhealed skins and other defects. Atlas records colour status, juice result, defect tolerance basis and inspection point together.

A grade standard is not a live physical price

Grades make lots comparable; they do not establish current supply or price. A delivered physical estimate still needs a defined species and variety, grade and claim status, size and count, maturity and juice evidence, origin and harvest, pack, condition and cold chain, current permitted observations, quantity, currency, Incoterm, destination, delivery window, freight and information vintage. Atlas withholds a physical estimate when those observations or usage rights are missing.

Questions procurement teams ask

Are lemons and limes one interchangeable Atlas commodity?

No. The page is a navigation cluster, but each physical lot keeps its species, commercial variety, grade, colour, maturity and buyer-use identity. Lemon requirements are not silently applied to Persian limes or vice versa.

What qualifies a lemon as seedless under the current USDA standard?

A 100-count composite sample may contain seeds in no more than six fruit. When the lot is marked seedless, at least 95 percent of containers, including consumer units, must carry the claim legibly.

What juice content does USDA require for Persian limes?

The USDA lime standard states at least 42 percent juice by volume or weight. The lot still needs grade, colour, condition, variety, size, origin and inspection evidence.

Which fields make fresh lemon or lime offers comparable?

Species and variety, exact grade, colour or turning designation, maturity, seedless claim and sample result for lemons, juice-content result for limes, count and diameter, defects and condition, origin and harvest, treatment and cold chain, pack, lot, quantity, currency, Incoterm, destination, delivery window and evidence date.
