Is 327331 the right code for a concrete block or paver manufacturer?

SBA uses that number for loan eligibility and federal agencies use it for small business set asides. A firm above it can still qualify for SBA 7(a) and 504 loans under the alternative standard of $15 million tangible net worth and $5 million average net income.

How do block and paver plants handle seasonality?
