RSC, HSC, OSC and FOL describe flap arrangements used in North American corrugated packaging. Identify the construction before comparing quotations or matching it to a FEFCO drawing.

AICC is an industry association, not a substitute for a box drawing. An ambiguous ASCC reference needs its original publication; do not treat it as a verified independent style-code system.

Box names and closure differences

The Fibre Box Association hosts transport classification material describing these constructions. The short names do not supply dimensions or material performance.

Reference	What it means	Design use
RSC	Regular slotted container; outer flaps meet.	Use for a conventional closed shipping case.
HSC	Half-slotted container; one set of flaps.	Plan open access or a separately specified cover.
OSC	Overlap slotted container; outer flaps overlap.	Specify the intended overlap, not just the abbreviation.
FOL	Full-overlap slotted container.	Review the complete overlap and sealing stack.
FPF	Five-panel folder, wrapped around the product.	A useful construction to compare for long articles.

Translate a brief without losing details

Supply a dimensioned drawing when translating between a supplier’s terminology and FEFCO. State whether a cover is included and how the case is joined and sealed.

AICC represents independent packaging businesses. Historical FEFCO/ESBO references should be checked against the publisher’s codebook rather than relabelled as an AICC or ASCC code.
