Fix Amazon feed issues

Amazon requires either an ASIN (Amazon Standard Identification Number) or a GTIN for every listing. Without one, the listing can't be created. Brand-gated categories require additional verification on top.

Affects: gtin

The product type assigned to the listing isn't valid for Amazon's category system. Amazon uses a deep, specific product-type taxonomy that doesn't accept free-form values.

Amazon's main-image policy is stricter than other channels — pure white background required, no logos, no watermarks, product fills at least 85% of frame. Failures suppress the listing.

Affects: image_link

Amazon requires fulfillment configuration on every listing — either FBA (Fulfilled by Amazon), FBM (Fulfilled by Merchant), or SFP (Seller Fulfilled Prime). Without it, the listing can't activate.

Amazon detected another listing for the same product (matching GTIN, brand, and key attributes). Amazon's catalog policy is one ASIN per product — duplicates are merged or suppressed.

Affects: id

Amazon gates many brands behind explicit authorisation. Without approval from the brand owner (or proof of authentic sourcing), you can't list products under that brand.

Affects: brand

Listing exists and is technically active, but Amazon has hidden it from search results due to data quality issues. Items don't appear in user searches even though the listing technically works.

Listing-specific buyer detail page has data inconsistencies. Often happens when seller-provided data conflicts with Amazon's canonical catalog data for the same ASIN.

Amazon's variation theme (how variants are grouped — by size, colour, etc.) doesn't match the actual attributes. Common when child SKUs have inconsistent attributes that don't fit Amazon's expected variation pattern.

Affects: item_group_id

Amazon's listing quality score is below the threshold for full visibility. Listings serve but get suppressed ranking — they appear lower in search and rarely win the Buy Box.

The brand value in the feed doesn't match what's registered for the ASIN in Amazon Brand Registry. For brand-registered ASINs, only the brand owner can edit canonical brand data — other sellers must match.

Affects: brand

Amazon gates entire categories — automotive parts, jewellery, watches, toys, beauty, supplements, fine art — behind approval gates. Without category approval, new sellers can't list in those categories regardless of brand.

Amazon's inventory count differs from your seller-reported quantity. For FBA, this means physical count differs from system count (lost/damaged units). For FBM, your system reports more units than Amazon shows available.

Item listed but not winning Buy Box. Listing appears in search but customers default to a competitor's offer. Driver of significant revenue loss because Buy Box wins most clicks.

Amazon's pricing algorithm flagged the price as anomalously high vs the typical range for the ASIN. Listing suppressed until price is adjusted or seller appeals.

Amazon flagged the price as suspiciously low. Common counterfeit-protection trigger. Listing may be suppressed pending verification.

Item appears to contain hazardous materials (battery, flammable, pressurised) but hasn't been classified. Amazon requires hazmat classification before items can ship.

Reported dimensions in the listing differ from what FBA measured at intake. Amazon adjusts dimensions to actual measurements; large discrepancies trigger this warning.

Listing condition (used, refurbished) is restricted in this category or for this brand. Listing exists but doesn't appear in search results.

Affects: condition

Amazon's tax compliance review flagged the seller account. Could be missing tax registration in nexus states, incorrect VAT collection, or sales tax filing gaps.

Brand owner has locked the ASIN's canonical attributes (title, description, images). Other sellers can only attach offers — they can't edit listing content.

Amazon requires two-step verification (2SV) on seller accounts. Accounts without 2SV are flagged and may face restrictions on listing changes or fund withdrawal.

Amazon refused to receive your inbound FBA shipment at the warehouse. Items intended for FBA storage couldn't be processed, leaving them in limbo.
