M350 and M2000 Codes in Badminton Shuttlecock Wholesale

A purchase order lands with one line on it: MAVIS 350 / 2000. Which shuttlecock are you actually buying? The item code answers that, and nothing else on the line does. M-2000 is one model. The M350 line is six separate codes. Both lines use the same White and Yellow and the same Slow, Medium and Fast, so the printed color and speed word will never tell you which of the two you are holding.

Everything below stays inside the captured YONEX MAVIS 350 and MAVIS 2000 pages; nothing here predicts another shuttle, another factory or a private-label build. Inside that boundary the working rule is narrow: the item code is the only field in these documents that separates one model line from the other, which means every quote line has to collapse to a single code before anyone signs it.

What the M-2000 Code Actually Locks Down

The M-2000 page states the model as MAVIS 2000, the item code as M-2000, the quantity as 1 tube / 6 shuttlecocks, the speeds as Slow, Medium and Fast, and the colors as White and Yellow.

Read the structure of that page rather than the words. Speed and color sit as attribute rows under a single model, not as sub-codes branching off it, because the code itself stops at model level. Which means M-2000 pins the model and the packing unit, one tube holding six shuttles, and nothing narrower than that. A line reading M-2000 is a valid model-level identifier; it is still not a commitment to a specific speed or color, so those two items have to be confirmed on the same line before the tube count means anything.

The manufacturer also describes the Mavis 2000 as designed to be the ultimate practice and tournament shuttlecock for club players. Treat that as a positioning sentence, not a measurement. It was written about a finished branded product, it carries no test record in these pages, and it does not travel onto a private-label build that a factory runs for you.

Why White and Fast Cannot Name a Model

White and Fast are descriptions, not identifiers. Both appear on both product lines.

The M-2000 page lists White and Yellow under colors and Fast under speeds. The M350 page hands you M350F for White / Fast and M350YS for Yellow / Slow, the same words sitting on a different code. A unique key only works if the field takes different values across the candidates you are choosing between, and White, Yellow, Fast, Medium and Slow all fail that test because both models list them. Which means a buyer holding nothing but a color and a speed word cannot establish which model is being quoted, no matter how confidently the sales email words it. Only the item code changes across the two lines in these captured pages.

That is why the code has to carry the decision.

Parsing Six M350 Codes Without Guessing

The M350 page lists six codes: M350S for White / Slow, M350M for White / Medium, M350F for White / Fast, M350YS for Yellow / Slow, M350YM for Yellow / Medium, and M350YF, which the same table labels Yellow / Slow.

Six codes cover three speeds times two colors. In the first five the trailing S, M or F matches the speed word and the Y marks yellow, the reason being that the suffix system stays internally consistent across those five entries. The sixth does not fit: M350YF carries the F suffix and is still written Yellow / Slow on the page. That is a recording conflict inside the source, not a naming convention you get to finish for them. Do not rewrite it to Fast, and do not let anyone on your team assume it ships as a fast ball because of the F. Enter it exactly as the page has it, flag it as an open question in writing, and keep the original wording beside your own so the paper trail shows who said what.

The Order-Line Sequence From Quote to Confirmation

Take the quote and rebuild it line by line. First move: every quoted line gets rewritten as one of the seven codes, M-2000, M350S, M350M, M350F, M350YS, M350YM, M350YF, one code per line. A line that still reads 350 / 2000 is not a line yet; it is two product families wearing one price.

Second move: quantity goes down twice, in tubes and in shuttles, using the packing unit of 1 tube / 6 shuttlecocks. The two numbers have to convert into each other without a remainder, and if they don't, the quantity basis is not settled. Third move: put the color and the speed word to the right of the code as a description, never in place of it, and settle any disagreement in the code's favor while you write down that the disagreement existed. Fourth move: anything that cannot be expressed as one of those seven codes goes to a pending list instead of onto the order.

Price, MOQ, lead time, capacity and customization rights stay blank at this stage. Nothing in these pages answers them, and a blank you fill from memory is worse than a blank left open for a written reply.

Speed Caps Are Temperature Codes, Not Grades

The M350 page ties its caps to ambient temperature: green cap for Slow at 22–33 Celsius, blue cap for Medium at 12–23 Celsius, red cap for Fast at 0–13 Celsius.

Work back from air. A shuttle travels through a fluid, and how far it gets before it drops depends on how dense that fluid is on the day. Cold air is denser and drags harder, so the shuttle decelerates faster; you compensate with a faster grade, which is why Fast is the cold-weather code at 0–13 Celsius while Slow covers the warm end at 22–33 Celsius. Speed words are therefore a code for the conditions on the day, which means they are not a quality ladder you can rank one model against another. A fast M350 and a fast M-2000 are both fast under the same physics, and neither is the better shuttle for being fast.

The bands also overlap. 22–23 Celsius falls inside both Slow and Medium; 12–13 Celsius falls inside both Medium and Fast. That comes down to a boundary drawn by people, not a step change in physics, so at 22 Celsius either code can be defended on court. Neither can be defended on an invoice as the only correct one, which is why the buyer's job at those temperatures is to name the code the players want rather than to argue about which one is right.

The captured M-2000 page carries no cap colors and no temperature table at all. Do not paste the M350 ranges onto M-2000's Slow, Medium and Fast and call the result a spec. If temperature selection matters for your account, that is a question for the supplier, not an inference for the purchase order.

Three Checks That Confirm the Line Is Right

First check, code membership: every line's code must sit inside the seven recorded codes and match what your purchase order says. A code outside that set is unconfirmed by definition. Second check, packing math: shuttles divided by six has to give a whole number of tubes; a remainder means the quantity basis is still being negotiated, not a rounding problem to fix later. Third check, description consistency: the color and speed words must point the same direction as the suffix, and the one permitted exception is M350YF, which stays on the record with a written question attached.

A line is done when three things are true at once: the supplier gives one code per line, gives the quantity in tubes and in shuttles, and gives a clear written answer on M350YF. Two out of three is an unfinished line. Hold it.

What the Source Documents Leave Unanswered

There is no price, MOQ, lead time, production capacity or customization permission anywhere in these pages, and nothing here is backed by a sample you or I have tested, a batch run or a certification report. Those blanks are not a flaw in the method; they are the edge of what a model page can tell a buyer. The manufacturer's line about the Mavis 2000 being built for club practice and tournament play describes a finished branded product, and it does not become a promise about your private-label run.

So turn each gap into a question the supplier has to answer in writing: which code exactly, how many tubes and how many shuttles, what the M350YF speed actually is, and what the price and minimum are for that specific code. Items with no written answer stay out of any price comparison, because a comparison built on a fuzzy line compares nothing.

Back to that one-line quote. MAVIS 350 / 2000 has to come apart into seven codes, quantities carried in both tubes and shuttles at six per tube, and one written confirmation filed next to M350YF. A supplier who will only repeat 350 / 2000 back to you has given you nothing you can accept against, and the correct decision on that quote is to leave it unsigned until the codes are on the page.
