METHODOLOGY

How the numbers are calculated

This page reads the same rules list the app calculates from, so the two always match.

Obligations

For each state you sell into, we compare your global annual revenue with the state's small-producer revenue threshold and, where a state has one, your supplied tonnage with its tonnage threshold. Below a threshold reads likely exempt. If a state has published no threshold, we treat you as covered until one is confirmed; we never mark it exempt.

Supplied weights

Weight = approved component weight (grams) × units sold into the state in the reporting year, converted at 453.592 g per lb and 2,000 lb per short ton. Only reviewer-approved components count. Draft or AI-proposed values are excluded.

Fee estimates

Estimated fee = pounds per material category × the published rate for that category and year. Where a state has not published rates, we show weights only. Preliminary rates are labeled preliminary.

Estimate based on published rules and your inputs. Not legal advice. Confirm borderline cases with your PRO or a qualified advisor.

Maryland and Washington have no published thresholds or rates yet, so they have no rows above. See state obligations.
