Grading & Size Standards for Fresh Produce Export

Key definition: Fresh produce for export is graded into quality classes — Extra, Class I and Class II under EU marketing standards — and sized by diameter, weight, or count per carton. Citrus is sized by fruit diameter (oranges have a 53 mm minimum; mandarins and lemons 45 mm) or by count per carton, while mango is graded by fruit weight and count. Each class sets the allowed defect tolerance, and a 10% size tolerance applies across all classes.

Grading and size standards for fresh produce export: quality classes, size counts, Brix targets and defect tolerances for fruits and vegetables — Grading sorts produce into quality classes and size grades that buyers specify in every order.

What Grading & Size Standards Are

Grading is the sorting of harvested produce into uniform lots by quality and size so that buyers know exactly what they are purchasing. International trade in fruit and vegetables follows recognised marketing standards — principally the EU marketing standards under Commission Implementing Regulation (EU) No 543/2011, the Codex Alimentarius commodity standards, and the UNECE standards. These define quality classes, sizing methods, maturity, and the tolerances allowed at each marketing stage.

For an exporter, grading determines price, market access, and buyer satisfaction. A retail chain in the EU will specify a quality class and a size count; a juice processor will accept wider grades. This page summarises the grading framework for the produce Egypt exports most, and links to our product guides for variety-specific detail.

The Three Quality Classes

Under EU marketing standards, fresh produce is graded into three classes. The class determines how much visual imperfection is permitted while the fruit still retains its essential quality, keeping quality, and presentation.

Class	Quality Level	Defects Allowed	Typical Use
Extra	Superior quality	Virtually none; only very slight superficial defects	Premium retail, quality-focused markets
Class I	Good quality	Slight defects in shape, colour or skin permitted	Mainstream supermarket retail
Class II	Marketable quality	More skin blemishes and shape variation; still sound	Wholesale, food service, processing

EU quality classes for fresh fruit and vegetables (Reg 543/2011). All classes must be sound, clean, and free of decay.

Citrus Size Standards

Citrus is sized by the maximum diameter of the equatorial section of the fruit, or by count per carton. The EU assigns size codes referenced to diameter; in practice, importers order by count (the number of fruit in a standard carton). Smaller counts mean larger fruit.

Citrus	Minimum Diameter (EU)	Typical Export Counts	Sizing Basis
Oranges	53 mm	36–113 per 15 kg carton	Diameter / count; EU size codes 0–10
Mandarins & Clementines	45 mm	Count per 10 kg carton	Diameter / count; EU size codes 1–10
Lemons & Limes	45 mm	Count per carton	Diameter / count
Grapefruit	Sized by diameter / count	Count per carton	Diameter / count

Citrus minimum sizes and sizing basis under EU marketing standards. Popular orange export sizes are counts 48, 56 and 64.

For variety-by-variety specifications, sizing, and Brix detail, see our Complete Guide to Egyptian Citrus Export. The exact EU size-code to diameter table is set out in Annex I of Regulation 543/2011.

Mango Size Standards

Mango is graded by fruit weight and by count per carton rather than by diameter. A standard 4 kg export carton holds a fixed count, and the count corresponds to an average fruit-weight band. Smaller counts mean larger fruit.

Count (per 4 kg carton)	Approx. Fruit Weight	Size Grade
6–7	550–650 g	Extra large
8–9	450–550 g	Large
10–12	330–450 g	Medium
14–16	250–330 g	Small

Indicative Egyptian mango size grades by count per 4 kg carton. Exact bands vary by variety and buyer specification.

Mango grading also accounts for maturity, skin finish, and freedom from latent defects. See our Egyptian Mango Export Guide and Egyptian Mango Export Requirements for variety-specific grades and handling.

Brix & Maturity Targets

Brix measures total soluble solids (mainly sugars) and is a key maturity and sweetness indicator. Under EU standards, citrus maturity is defined by minimum juice content and a sugar-to-acid ratio rather than Brix alone, but commercial buyers commonly set Brix targets. The figures below are typical commercial targets, not regulatory minimums.

Produce	Typical Brix Target	Notes
Oranges	10–13°	EU also requires min. juice content & sugar/acid ratio
Mandarins	10–12°	Sweet, easy-peel preferred
Mangoes	12–16°	Rises during ripening; harvested mature-green
Table Grapes	16–18°	Min. ~16° for export quality
Pomegranates	15°+	High Brix with balanced acidity
Strawberries	7°+	Flavour-driven; varies by variety
Watermelons	10°+	Key acceptance criterion

Typical commercial Brix targets. Actual specifications are set per buyer and variety.

Defect & Size Tolerances

Standards allow a defined percentage of a lot to fall short of its stated class or size — recognising that perfect uniformity is impossible. For citrus under Reg 543/2011:

Quality tolerance — Extra: 5% by number or weight may fall to Class I quality.
Quality tolerance — Class I: 10% may fall to Class II quality.
Quality tolerance — Class II: 10% may fall short of Class II minimums (but must remain fit for consumption).
Size tolerance — all classes: 10% by number or weight may be one size larger or smaller than the marked size.
Size uniformity within a package: the diameter range must not exceed 10 mm (fruit <60 mm), 15 mm (60–80 mm), or 20 mm (≥80 mm).

In all classes the produce must be sound, clean, free of decay, pests, and abnormal external moisture. The exact tolerances differ slightly by commodity and standard.

Frequently Asked Questions

What are the quality classes for fresh produce?

Under EU marketing standards, fresh produce is graded into three classes: Extra (superior quality, virtually no defects), Class I (good quality, slight defects allowed), and Class II (marketable quality with more blemishes). All classes must be sound, clean, and free of decay.

How are oranges sized for export?

Oranges are sized by the maximum equatorial diameter or by count per 15 kg carton, with a 53 mm minimum diameter under EU standards. Popular export sizes are counts 48, 56 and 64 — a smaller count means larger fruit.

How is mango graded by size?

Mango is graded by fruit weight and count per 4 kg carton rather than by diameter. For example, a count of 6–7 corresponds to extra-large fruit of roughly 550–650 g, while a count of 14–16 is small fruit of around 250–330 g.

What Brix level is needed for export fruit?

Brix targets vary by crop: roughly 10–13° for oranges, 12–16° for mangoes, 16–18° for table grapes, and 7°+ for strawberries. These are typical commercial targets; EU citrus maturity is defined by juice content and sugar-to-acid ratio rather than Brix alone.

What size tolerance is allowed in a shipment?

Under EU citrus standards a total size tolerance of 10% by number or weight is allowed — fruit one size larger or smaller than the marked size. Within a package the diameter range is also limited (for example a maximum 10 mm spread for fruit under 60 mm).
