Recent seasonal comparison
Weighted average price = Σ sales value ÷ Σ quantity
Low-volume observation — trading volume is unusually low for this item and time of year; the weighted average price may not be representative.
5-year seasonal benchmark: The 5-year seasonal benchmark price is the arithmetic average of each eligible year's weighted average price for that month. It gives each eligible year equal weight and is not a single weighted average calculated by pooling five years of sales value and volume. Benchmark volume is the arithmetic average of eligible yearly monthly volumes. Missing observations are excluded, not treated as zero.

Prices and benchmarks: Weighted average price = Σ sales value ÷ Σ quantity. The 5-year seasonal benchmark gives each eligible year's monthly weighted price equal weight; missing observations are excluded.
Shipping origin: This is the reported shipping origin and may differ from the product's country of production.
Warnings: A low-volume warning appears when monthly quantity is below 10% of the median for the same month across up to five preceding observed years, with at least three preceding observations, and is 50 kg or less. A wide-price-range warning is interpretive only; reported observations remain unchanged.
Units and missing periods: Source quantities are stored in exact kg. Charts display volume in MT, while detailed values retain kg where appropriate. Missing periods are not filled or smoothed, and no observations are removed as outliers.
