Harmonics color finder: Costco laminate part numbers
Harmonics was the warehouse-club laminate Costco sold, a line associated with Mohawk. Buyers mention Premium Oak from about 2004, Vintage Chestnut around 2009 and Golden Aspen until about 2014. Costco carried a color for a while and then cleared it. The style later showed up on manufacturer depleted lists, so there has never been a store reorder path for an old Harmonics floor.
Harmonics cartons use three kinds of code. Some carry a short part code such as AH404S, RM203S or VC403S. Others carry a longer Mohawk-style string such as 33280-FO201, and some show only a Costco item number such as 1054504 or 511430. Several colors, including Skyline Maple, Brazilian Cherry, Cottage Oak and Harvest Oak, often appear on depleted lists with no code at all, so the brand strip and color name have to carry the match. Published thickness figures are rare. Before buying, measure a spare plank including any attached pad, and compare the click joint.
Costco shoppers tended to buy whole rooms at once, so surplus cartons are common. FlooringFX has years of Harmonics offers and requests in its comment archive, and sellers often hold several boxes of a single color.

Discontinued means a dated retailer or manufacturer page, or an archived copy of one, says the floor is no longer sold. Depleted means the color appears on a manufacturer depleted list, which is how Costco and Lowe’s house-brand floors usually show up once they are gone. Not dated marks colors from reader cartons in the decoder, where the model string is on file but no dated status source is. Still listed when checked means a store page was live at the last check; the model number is here so you can match leftovers exactly.
